CyanogenMod 9 is a free, community built, aftermarket firmware distribution of Android 4.0 Ice Cream Sandwich. It is designed to increase performance and reliability over stock Android firmware. Yup, I revisit CyanogenMod custom ROM after signed petition to Samsung Mobile. CM7 ROM for Samsung Galaxy S II was not that good during my testing last year. How about the latest nightly CM9 Android 4.0.3 ICS ROM for Samsung Galaxy S2? Let’s find out while waiting for the official ICS firmware from Samsung…




CM9 Android 4.0 ICS ROM for Samsung Galaxy S2 definitely looks better than before. It is fast, smooth and looks great. However, it still has several bugs / missing features on the nightly ROM that I tested. I can’t play video at all. Non-functional MHL TV-Out yet. By the way, Google Applications like Android Market does not come along with CM9 ROM. You need to install them yourself with CWM manually. Try it out, you might love it.

hello again,
im addicted with this phone, now i want ICS, i searched the net and found this version what do you think about it? XXLPB Firmware
thank you
No idea as I did not test it. I will wait for official ICS firmware which will be released in this month.
Hello,
Now i am confused which one to download STABLE or NIGHTLY? Whats the difference between them?
And which of Gingerbread are good on SGS2? 2.3.6 or 2.3.5?
Thank you,
Nightly is the latest build but might contain bugs.
Both are the same to me.

hey jaycee,
i wanted to install custom rom on samsung galaxy s2 which is some OLLEH carrier, i dont know where it is from.
anyway, i downloaded the ke7, ke2 and ke4 versions, but everytime i try installing a cm7,cm9 rom from clockworkmod it gives me status 7 issue and aborts it.
am i missing something? kindly reply me asap.
Sorry, no idea about it. Try to ask other at XDA website see.
I can recommend WanamLite ICS Rom V.9. It’s bug free fast and very battery friendly.

In all honesty I did have some troubles with keyboard lockup in V8.9. It was fixed by using a market keyboard. Don’t know if that bug is in 9.0 but if so it’s a minor issue imo.
Looking forward to try stable CM9
hi jayce .. is this is good as checkrom hd revolution?,, thanks

Not perfect yet.
hi jayce i m running cm7 on sgs2 and not happy with it how can i go back to stock without losing root.

Stock firmware does not have root access by default. You need to root it manually after installed it.

thanks again for all your help.

i keep pending on loading…which show “S” galaxy s2…
so..i there anything i did wrong..n any idea how to fix?? T.T
Hi husny, did you wipe data and cache in CWM?
yes..i did..
Weird… You should be able to load into Android OS after wiping all. Try to wipe and install firmware again.
that the problem…i cant go into OS..it keep loading ><
i can only go into odin mode (power+home+volume down)
how to wipe out if i cant go into OS??
Load into recovery mode ( power + home + volume UP ) . Not Odin.
aahhhh..i dont try that..lol..
my bad..worst case scenario..i already send back my phone to home town T.T
i will came back to you later with go0d news..i hope so =)

Ps: i have some kind of problem,
it looks like there is a small part out of my glass
But isn’t gorilla glass really though? 2 months old phone
Pss: sorry if this is messy, on my gs2 right now
for my case…cm9 nightly (29/04/2012)
i can play some video…the only thing i concern is mobile data…
cant do nothing about it..even cant create & save new APN.
still no idea admin…need help..huhu
Try to consult CM9 developers.
problem solved after reboot..APN setting for celcom was there…only prob it show no services at notification even tho my phone line work just fine.. ^^
Hi
I’m problem pls tell. cm9 zip install is not working . E:signature verification failed ?
if i not mistaken…you need to flash clockmod recovery 1st (at ROM Manager)
select your phone model..then proceed…

Hi Jayce,
There is no chinese (简体) input on the cm9, it just doesnt appear on the list, i was wondering if you know how to add in the chinese input language for the keyboard.
Hi Esmond, just install Google Pinyin IME.
https://play.google.com/store/apps/details?id=com.google.android.inputmethod.pinyin
Thanks for the quick reply jayce!
I am fairly new to android and of coz flashing. Another question i have is how do i access files on my internal sd card. On the stock OS, there was this app called “my files” but on CM9 i cant find the equivalent.
Take your time to wonder around Google Play Store then. Lot of useful applications there. Just use the search function. You will find most of the stuffs you need.

Hi Ahmed, can you still load CWM or Odin Download mode?
No way, its not even start, not detecting completely Dead.
Sorry Ahmed, I have no idea then. Please consult Samsung Support.
Dear Ahmed,
It is probably too late now. But if your phone is still “dead”, then you may want to try a so called JIG plug. In many cases it can make your phone boot into download mode:
– remove the battery of yor phone,
– plug in the JIG,
– waiting 30 seconds
– put the battery back in
and then your phone hopefully boots into download mode, where you can use Odin as usual.
There are many places, where you can buy such a plug.
Good luck
Francesco
