CyanogenMod 7.1 is out. CyanogenMod is an aftermarket firmware based on open-source Android operating system. It is a light and fast Android ROM for my HTC HD2. If you want the latest Android version, CM is the one that you want to get. There are stable mod, experimental mod and nightly build for you to play with. And good news for Samsung Galaxy S II users because official CyanogenMod support for the Samsung Galaxy S II was added in CyanogenMod 7.1.

CyanogenMod 7.1 Stable Version
These are the latest supported devices in CyanogenMod 7.1 – HTC Desire S, HTC Incredible S, HTC Incredible 2, LG Optimus 2X, T-Mobile G2x, Motorola Backflip (Motus), Motorola Cliq / Cliq XT, Motorola Defy, Motorola Droid 2, Motorola Droid X, Samsung Captivate, Samsung Fascinate, Samsung Mesmerize, Samsung Showcase, Samsung Vibrant, Samsung Galaxy S, Samsung Galaxy S2, Sony Ericsson Xperia X8, Sony Ericsson Xperia Mini, Sony Ericsson Xperia Mini Pro, Sony Ericsson Xperia Neo, Sony Ericsson Xperia Play, Sony Ericsson Xperia Ray, Sony Ericsson Xperia Arc and ZTE V9…
Try CyanogenMod 7.1 out if you anyone of the above Android phone. Download CM 7.1 stable version here.

wow,finally CyanogenMod stable rom has arrive so how can i install tis stable CyanogenMod .
Use ClockworkMod Recovery to install.
Hi Jayce,
Which ROM should I select coz HTC HD2 is not in the list. Can’t wait to try this stable ROM.
Thanks
Oh, there is no official CM support for HTC HD2. You need to wait for HD2 ROM chef to cook from HTC Desire build.
Guess I have to wait. Lately just know how to install thru CM Recovery successfully. I know is very slow pickup of me. But how to back up and install back all the setting from old to new ROM installed.
Thanks

Thanks for the info. It helps a lot
Hi Jayce,
I have big prob here. I did the BackUp with Titanium. Then moved all the apps to SD by Titanium. When Switch OFF and On again. All the apps seems to vanish when Reboot. Why this thing can happen? I even try to Restore by Titanium buy crash in half way.
This problem really troubling me. Please help…..
Thanks
I did not try to move apps to SD with TB before. You might want to check with TB developer on your issue.
Ok. I moved all the apps back to internal memory. Which I suppose should be in Ext3 of SD card. Then all the apps remains after each Boot up. That shouldn’t be an issue to slowing down the speed of the processor right? Cause the phone assume that Ext3 is the whole memory space for it. My Ext3 is 1024Mb and still has 660Mb free after all the apps moved in.
Thanks
u mean follow the same procedure as Download Androidmeda HyperDroid ROM for Samsung Galaxy S2 (CWM)
Yes, most of custom firmware use CWM method to install.
Dear Jayce,
I’ve visited the cyanogen wed and find this update on stable mode: update-cm-7.1.0-GalaxyS2-signed.zip
Is it the file is the right one? since it just 99.47mb compare to others rom like androidmeda and darky which is more than 300++mb
Yes, CM is a light ROM. So the size is smaller than normal Samsung firmware. Err… I can’t confirm the exact file size as CM website is down now.
after installing Androidmeda HyperDroid ROM ,i can,t find my titanium apps in my phone??
Wipe data and cache delete all previous installed applications. You need to install Titanium Backup back yourself. Then use it to restore other apps and data.
hi Jayce,
does “stable” mean it can run most apps/games for sgs2?
what is the quadrant score of this rom?
No idea. I am still having problem to download the firmware. CM website is down…
Personally, I will stay with custom firmware based on official Samsung firmware. CM7 is still new for SGS2.
jayce, i alry install CyanogenMod 7.1 but after reboot it juz stuck at galaxy logo not moving . first i copy zip file than paste to sdcard than follow all cwm procedure to install.
Go back to clockwork recovery and install it again.
Need urgent Help!! : [
hi jayce…when i try to install it says intsalllation aborted…files not found …i have copied the stable rom .zip file to the root of sdcard..but some issue..pls helpp.
CM server is quite busy and down during my download. My downloaded zip file was not completed. Make sure that your downloaded zip file is not corrupted.
jayce, juz wan to tell u tat finally i got CyanogenMod on my phone .i redo all the procedure again & it work,it look so beautiful & classic juz love it.CHEERS
Weird… I have the same problem on CM nightly. Need to install the zip twice. Then okay.
hi jayce
the error says
E: failed to verify whole file signature
E: signature verification failed.
hi, chetan u must copy the zip file to ur com do not extract the zip file than copy & paste to sdcard,from there juz follow all cwm procedure to install.
Currently using CM7.1 on my SGS2 for about an hour now.
-Do not detect external SD
-Camera crashes most of the time
-Cannot install apps from market several times.
Overclocked to 1.6 ghz, Quadrant Standard Score : 4448
Thanks for the info. Guess that the stable version for SGS2 is still not that stable.
Wow, your SGS2 can go up to 1.6 GHz. Mine always crash at that speed. How much voltage did you use?
I’ve OC’d the phone by tweaking the performance setting in CM setting, with both Min and Max frequency at 1600 MHz just to test how long will it take to crash the phone. I didn’t tweak the voltage though.
Been using this OC’d setting since morning , played almost all the Gameloft games. streaming youtube, playing HD videos and browsing the Internet, but no crashes yet.
Quadrant Standard Score is around 4800-5200
but the camera and other camera related apps crashes a lot though. Sigh.
btw, all the SD card contents can be accessed in /mnt/emmc/
Cool… Will test to overclock when I am free.
CM 7.1 is not at all stable..installed and used it for 6hrs..not stable..when i press the power or home button screen stays black..
my CM 7.1 so far so good but wit sme minor problem. -how can i get back my stock video player -i can’t find my cwm & android market – external SD totally empty -MAP app gone
Stock video player only come with Samsung firmware. Or I should say all the Samsung apps are gone…
yep,samsung apps all gone : ) must i root again to get cwm apps.
CM builtin video player not so good.
android market gone.
external SD totally empty.
MAP app gone
Just boot into CWM will do.
how??????
http://www.jayceooi.com/2011/08/03/samsung-galaxy-s2-clockworkmod-recovery-mode/
jayce,after install CM 7.1 do i need to root my phone again?
It should be rooted by default if not mistaken.
why i cun dowload android market apps : [
Did you connect to Internet? It will show up when you are connected.
refer this , maybe this will help http://forum.xda-developers.com/showthread.php?t=1297557&page=9
I installed the recovery boot and i booted it on this cm7.1 and then i used odin and downloaded a random code CF-root so does any1 know the CF-root for this so i can open my phone now it wont open or get up only way is via usb and then u can get it into odin mode.
Err… What is your issue now? I don’t get it.
Market missing and 3G internet doesnt work
Morning jayce, i juz did cwm recovery mode but still cun find cwm on my phone?
Turn off Samsung Galaxy S 2.
Press and hold down Volume Up + Home + Power buttons at the same time.
Release all buttons when you see SGS2 Logo.
ClockworkMod Recovery will be loaded then.
press reboot .
Then what does it load?
@Antonio: Personally, I don’t feel any slowness with apps in EXT3 partition. And what choice do we have since HTC HD2 does not have much internal disk space…
-reboot system now
-apply update from sdcard
-wipe data/factory reset
-wipe cache partition
-install zip from sdcard
-backup and restore
-mounts and storage
-advanced
-power off
-++++GO BACK+++
Yes, this is CWM. What do you want to load then?
load? wat i mean is before i install CM7.1 i got cwm app on my phone but after i install CM 7.1 i cun find cwm app on my phone.
Err… CWM and CWM Manager is 2 things la.
CWM Manager comes with CF-Root. Installing CM7 already deleted it.
huh! how stupid i am : (
hey,how ur xxki3 going….isit good
Nobody is stupid. We all are here to learn. And learn…
XXKI3 serves me well so far.
u r right ,we r here to learn.: )
1) if i wan to install XXKI3 from CM 7.1 wat r the thing i need to do.
2)i cun even install market or titanium to my phone. : [
1. http://www.jayceooi.com/2011/09/25/download-official-android-2-3-5-gingerbread-rom-for-samsung-galaxy-s2-odin/
2. Install Google Apps addon with CWM. Like the way you install CM7 zip.
jayce,i juz check the other posts by adzha and refer this , maybe this will help http://forum.xda-developers.com/showthread.php?t=1297557&page=9

Noob question .. WHERES THE MARKET?
Install Google addons. After that add google account. You’ll see the market.

Nope.
BRO Thanks for the info, It helps a lot. : )
hey jayce have you tested this one before i install
Not yet. Maybe I won’t test it after reading other comments.
yeah, me too. scary
Hi all, it seems CyanogenMod 7.1 stable is now reclassified to a “release candidate” status due to the bugs found and feedbacks gathered.
http://forum.cyanogenmod.com/topic/33171-what-happened-to-stable/
jayce, i’m not sure if posting the above link on your blog is a violation of your policies. apologies if it is. my intention is just to share the news.
Yup, I read this too. Thanks for the info. No worry about posting useful link.
Ok. Cool:) I hope the new stable release is out soon.. So that I can use it before ICS is released on SGS II in the near future:D
Sorry if i made u mad was not my intention. Im having trouble loading the android rom when im in clockwork mod i followed your video to a tee when i press install from SD card it starts to load then it Aborted dont know why any tips thanks very much
Which ROM did you install?
the new CM Roman 7.1 I transfer the Rom went threw the steps and when I select install Rom from SD card it aborts action.
You are installing on your HTC HD2 or Samsung Galaxy S2? Or other device?
on the hd2
Oh dear, CM does not have official version HTC HD2. Use custom CM7 ROM for HD2 like http://www.jayceooi.com/2011/10/04/download-android-2-3-7-cm7-nand-a2sd-zip-rom-for-htc-hd2/
hi,jayce i hav been using CM 7.1 for 6 days everything fine tats no hang or lag until now.smooth & faster scrolling between apps & after install google addons now i can use android market again : )
Hi, Kelvin. how about the battery life and temperature?
hi,DM21 my stock rom battery within 1 day of moderate use,temperature within abt half 2 1 hr u can feel the heat now using CM 7.1 ROM can feel the diffference alot.
Battery moderate use abt 2 days. : )
temperature use mre than few hrs dun really feel much heat. : ]
hi jayce, why my CWM is not working when i’m trying to back up my file and restore it, but while when i’m using titanium back up its working properly bot back up and restoring save files,, also i would like to ask i can’t install cyanogenmod-7-1 using CWM… appreciated your feedback
Are you using CF-Root CWM?
CM7 is a bit special for Galaxy S2. I need to wipe data and cache then install firmware. And repeat this process again in order to get it installed. Failed boot loop on first installation.
yeah i’m using CWM did you remember when i’m facing recovery to my old file,, when i root my sg2 change the room to ginger bread 2.3.4 i go to http://androidadvices.com which is totally different from your instruction, but the same ODIN i use when i root,, do you think it affect.. when i update to 2.3.4 rom i follow the instruction as follows from http://androidadvices.com i dowloaded the 2.3.4 Package from this site,, then i extract,, after then i open odin 1.83, the extracted file has consist of the following file CODE_I9100XXKG2_CL375027_REV02_user_low_ship.tar , GT-I9100-CSC-HOME-MULTI-OXAKG2.tar ,GT-I9100-CSC-MULTI-OXAKG2.tar.md5, KERNEL_I9100XXKG2_CL375027_REV02_user_low_ship.tar.md5, MODEM_I9100XXKG2_REV_02_CL1037208.tar.md5 and i inserted to odin ,, not only in PDA as well as bootloader, phone and PIT,, and i successfully updated my mobile to 2.3.4 and now i change my rom to K13 which i get in your blog/site i mnage to update also,, but the CWM is not properly working for both backup and restore…please advice what will be the best remedy to my problem…thanks pLEase note that i cannot install also CM7 using CWM when i load through CMW its stock only in MID of installation
I don’t see that you are using CF-Root…
WHEN I INSTALL K13 I INSTALLED IT ALSO CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4 THIS IS THE RIGHT CF ROOT FOR K13 ISN’T
You should use XX_OXA_KI3 CF-Root.
yeah i used that
SEE, IN MY ABOUT PHONE IT SHOW EXACTLY;
MODEL NUMBER :GT-1900
ANDROID VERSION: 2.3.5
BASE BAND VERSION:I900XXK13
KERNEL VERSION: 2.6.35.7-I9100XXK13-CL577579
SE.INFRA@SEP-55#2
BUILD NUMBER:GINGERBREAD.XXK13
ITS SHOULD BE LIKE THIS?
We can’t know with these info because rooted and non rooted are having the same issue.
Are you able to load Android system recovery or ClockworkMod Recovery?

http://www.jayceooi.com/2011/08/03/samsung-galaxy-s2-clockworkmod-recovery-mode/
android system recovery! how can i load this CWM recovery…. i did press and hold volume up+home and power then i release when i see the sg2 logo but but when its loading it will appear
Android system recovery now CWM..may be there a problem inn my mobile and also when i’m trying to back up my files cwm is not working it will only create the back up file folder and and the it will prompt to reboot now and then it will will back-up,, but when you already rebooted if you will go to my files/clockwork-mode/backup it’s not appearing in the files?…thanks
You did not install CF-Root in this case. Else you will have ClockworkMod Recovery…
how can i install ClockworkMod Recovery? if i did not install Clockworkmode recover why the titanium back is working ?
As I mentioned, install CF-Root. You may have rooted your SGS2 but not with CF-Root. Rooted does not meant that you will have CWM.
hi jayce i try to root again and it is successful. one thing i have notice when i update my super user back up and restoring my files it didn’t work but now its ok and also i can access the root access menu . and one question when i rooted again my mobile its show the same in about my phone:

Hey Jayce!
I have a problem, i have installed the CM7 on my hd2 and everything works great.
BUT i cannot download any apps or games because I only have around 8mb internal memory.
How do I change so that the apps and games are downloaded directly to my SD?
I’ve tried to change it through the phone but the only option is to install them on the SD.
But I cannot download anything because of the low memory. Please help!
Which CM7 ROM are you using? And how much ClockworkMod Recovery Partition did you install?
http://www.jayceooi.com/2011/08/15/how-to-install-cwm-nand-android-on-htc-hd2-video/
added a new comment by mistake, but I use Typhoon CM7 3.6.8.
I used the same partition you did.
I have no further idea if you are using the same CWM partition as I did. Sorry…
TyphooN CM7 3.6.8
I dont remember but i read on one of your tutorials and i took the same amount of partition.
If you are able to check somewhere on the phone, I can do that if you tell me where.
Also, I have changed OS on my hd2 many times but i never seem to find one that is really good!
Is there anything you could suggest? I want something good with alot of available games and apps, that works!
CM7 ROM is great. MIUI ROM is good too. You can install apps and games from Android Market yourself.
jayce, now my browser force close everytime any idea to fix it.
Maybe you can hard reset it.
how??
Boot into CWM. Then wipe data and cache.
now i can use the browser again,thanks jayce u r great. : ]
hi Jayce
Got the below error
E: failed to verify whole file signature
E: signature verification failed.
What had you done until you got this error?
hi,if anyone is having problem wit MARKET FORCE CLOSE u can try tis menthod
GO to setting than go to language & keyboard
Change your phone language to anything other than ‘Hd (United States)
hi,jayce it me again now whenever i try to make out going call the call will call ended straight, pls advice : (
Look like not stable anymore. Try to wipe data and cache…
hi,jayce i found out why i cun call out it bcause my topup
validity day expires . : }
Morning Jayce,
I was just experimenting with this ROM this morning… After installing, i noticed i have no 3G connection. Unable to connect to the internet. Did i do anything wrong?
http://www.jayceooi.com/2011/01/20/apn-settings-for-android-to-enable-internet-mms/
it works now!!! haha. thanks a lot man:)
oh man… i think i messed up big time:( just now i wanted to restore my old backup through CWM recovery but i didn’t wipe data/factory reset or wipe cache. and it failed. so i just reboot again. it went on to load the cyanogenmod 7.1 but kee getting FC on android.process.acore (if i’m not mistaken). So i reselect reboot to recovery from the ROM manager. Now my screen is stuck at the Samsung Galaxy SII part and would not load into recovery mode. Any hope? Please say yes…
i can go into download mode.. maybe if i try flash back the stock firmware it will help?
Yes. http://www.jayceooi.com/2011/08/14/how-to-restore-stock-firmware-on-samsung-galaxy-s2-video/
Just boot into CWM if can. Wipe data and cache. Then restore it again.
I’m stuck at the boot logo at the moment. Will try to restrore the stock firmware when i get back tonight. Hopefully can go into recovery mode by then. Wish me luck!! hehe.
oh ya, since i cannot go into recovery mode at the moment, is it ok for me to skip step 1 to 6 in the video? I just need the recovery mode back… so i can restore my backup…
You can try since you can’t boot into CWM.
Phew…. luckily it worked. I managed to restore it to stock xxki3 before rooting and reinstalling checkrom revolution HD on my s2. Don’t want to ever go through that experience again. Haha!
What the different between CM7 Stable Mod,Experimental Mod and Nightly Builds.
It is stable to install in my galaxy s 2.
I don’t know the details too. But the naming explains them well. Stable, experimental and nightly.

Hi Jayce its me again! How can i install this cyanogenmod7 stable? i am coming from checkrom revolutionHD 2.0 which is not that stable(for me).. tnx!
Install like other CWM ROM. But CM7 needs to run the whole process twice. First time might have boot loop issue.
ahh there is no need to install the ROM Manager thing? so if i face a boot loop issue..i just need to go back to recovery mode and repeat the whole process again? is it ok if im coming from checkrom?
No. Yes. Ok.
Ah okei sir thank you!
worked fine but missed my old stock rom.
am using cm7 sd version of android on my htc hd2, works very smooth but unable to sync with my pc using htcsync, there isnt any option to choose usb connection tyoe after connection usb to pc. Pls help.
HTC Sync only work on HTC Sense build Android ROM. CM7 ROM cannot.
do u have any link where i can download
Android CM7.1 – 2.3.7 Gingerbread SD on my HD2
http://forum.xda-developers.com/forumdisplay.php?f=735
why this rom doesnt contain android market…and from where to download apps in this rom
No idea. But you can install it youself with Google Apps addon.
http://forum.xda-developers.com/showthread.php?t=1297557
then what are d benefits of using cynogenmod rom over stock android rom
CM7 is lighter and faster on HTC HD2. But on SGS2 is not really that great because not all the functions are working smoothly yet.
Jayce, what is the best ROM you have used on your SGS2 so far?
I also want to know..which best rom on galaxy s2??
Using CheckROM RevolutionHD now.
I prefer CheckROM RevolutionHD.
what is difference among different mods like nightly,stable,experimental……..
which one is the best………
Please refer CyanogenMod team for detail. For me, stable is the best.
Hi Jayce thanks for your support
but there is no market in it
Install Google Apps addon from XDA.

Hi Jayce, I have a T-Mobile G2x and I want to dowload ” CyanogenMod 7.1 ” Do I need to root first or just use ClockworkMod Recovery ? This will be my first custom Rom on this phone, I also have a HTC-HD2 but don’t remember what I did first…lol
I don’t have T-Mobile G2x. But I think you just ClockworkMod Recovery to install CWM type Android ROM.
i need a real time hep jayce……!!!!

Sorry, I don’t have ZTE Blade. No idea…
Jayce,I flashed CM7 but camera isnt working and sdcard is not being detected.
now,when i try to restore from CWM,after clicking restore,no files are being displayed(though I have taken NAND backup before flashing CM7)
How do I restore back now?I didnt want to flash stock through ODIN so I ensured I would just back it up with NAND,but no files being displayed,probably because I took back up on ext sd and CM7 fails to detect it
The backup file should be stored in either internal or external SD card. Just copy it to other one that don’t have it.
i am using HTC Desire S phone and lately i upgrade my android version 2.3.3 to 2.3.5. after upgrading it started giving me problem. the dislpay give problem after receving a call on the phone. please help me out.

Sorry sunil, I don’t have Desire S. Not too sure what is your problem. You can try to factory reset your phone see.
lots of errors than its benefit, i will stick to stock rom + speedmod instead…
Hi, I have a few questions:
1. On what Android version is CyanogenMod 7.1 based on ?
2. Now I have Gingerbread 2.3.5 is it safe to install this one ?
3. Does it matter what ROM i have before I install a custom ROM ? For example can I go from CyanogenMod 7.1 to Lite’ning lets say or the other way around ?
1. 2.3.7 if not mistaken.
2. Yes.
3. No, just make sure that you wipe data and cache in CWM before install new ROM.
Thanks so much for your response Jayce, I have one more question,
Where do I copy the two files to install CM 7.1 and gapps for Google Apps,
in the Internal SD or the External SD Card ?
Depend on your CWM version. External SD card for CWM v5.
Right, thanks Jayce !
Hi Jayce,
I have LG T-Mobile G2x (P999DW), I was trying to upgrade and during upgradation the phone hanged and it just shows me that S/W upgrading, nothing else happens.
Can you please guide how should I reload the software (if there is any link on Youtube or something) or could you please guide?
Sorry Mowgli, I don’t have LG T-Mobile G2x. No idea at all. Sorry…
I tried all the options from unlockr.com by reinstalling CWM but still when i re-boot the same screen pops up of S/W upgrading please wait…
My screen is just showing a CM animation over and over, what’s happening?
Hi Darren, try factory reset it. And reinstall Android ROM again.
