It’s time to restore Samsung Galaxy S2 with ClockworkMod Recovery when you face issues like applications always force close, data loss… Of course, you need to have a backup Samsung Galaxy S2 with ClockworkMod Recovery first in order to do a restore. You can use CWM Manager application to restore if you install CWM through CF-Root. Else load ClockworkMod Recovery to restore. CWM has Advanced Restore feature which can restore each component individually like boot, system, data, cache and sd-ext. Below video will guide you to restore Samsung Galaxy S2 by using CWM Manager. Read the step by step guide for more information…
Restore via CWM Manager
- Open CWM Manager.
- Click on Restore ~ Restore an existing backup.
- Select the image that you want to restore then click Restore.
- That’s all.
Restore via ClockworkMod Recovery
- Turn off Samsung Galaxy S2.
- 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.
- Go to backup and restore.
- Select Restore (or Advanced Restore).
- Choose the image that you want to restore.
- That’s all.
Enjoy new revive Samsung Galaxy S2!
thank you. very good video.
one more Q.
cwm will work when i uprade from current rom (tgy,2.3.3) to XXG5 ?
Yes, CWM Manger should be there. But you will need to reinstall ClockworkMod Recovery back by install CF-Root for KG5 again.
hi there. just want to check while doing nandroid backup to sd card …do u mean to external sd card or internal phone memory??
Internal phone memory – sdcard.
hi jayce…some more doubts.
1. the stock rom which i back up using nandroid will be stored in the internal memory right? if yes when i install the new custom rom, will that backed up will be erased?
2. when i restore back the original stock rom in any case will that rom will still be rooted?
3. in any unfortunate incident if my phone refuses to start up after installing a custom rom how should i restore the original rom…i mean can i still load the clockworkmod even if the phone is bricked?
4. in such case should i place my stock rom backup in internal memory or the external sd card.
im a newbie..thanks a lot for your patience in answering my queries. im learning a lot form u. thank u once again 🙂
1. No, it is stored at sdcard\clockworkmod\backup folder. Unless the custom firmware delete all internal USB storage (but this is very rare).
2. No. You need to root it again after back to stock firmware.
3. You can’t do anything if fully brick (won’t power on at all, again this is very rare). It is still okay for half brick (hang at SGS2 logo). You can boot into CWM or Odin to install firmware.
4. Personally, I keep a copy of CWM backup & Titanium Backup at external SD card and PC. 🙂
hi jayce,
i dont have a external sd card. is it compulsory? when i open my file manager on sgs2 i can see my internal memory named as sd_card. i tried backing up using mybackup pro and it backup everything to my internal memory..
and any custom rom which u would suggest which is by far the most stable without any issues :)..
thanks so much..u are doing a great job with this website..
No. It should be sdcard not sd_card, right? Custom ROM on your own taste. I still don’t have the time to test them thoroughly.
Hi Jayce! Can you tell me if this makes a total restore? or if after stock rom backup may i do my updates threw kies again?
Yes, it is a full system backup. If your stock firmware has CWM, then you can upgrade through Kies.
through KIES lol sorry my bad
hi jayce~ am a bit confuse here~
if i restore the backup-system after flashing a new different rom (not upgrading) does it mean i go back to the previous rom? or does it restore the data;apps;setting?
Personally, I did not use the advanced restore to restore each component. I use normal full system restore which will restore back everything (data, apps and settings).
so the newly installed rom is still intact and won’t be overwritten, isn’t it?
No, it will be restored with previous backup.
i have flashed my gs2 with the lite ning 6.1 custom rom after i felt that there is a battery drain more than usual “previous rom is the arabic one 2.3.3 kh1 i guess” i did a net search and find that lite-ning 6.1 is the most stable and less battery usage, but the problem persisted .. any suggestion , thank you
Try other firmware. Or tweak it – https://www.jayceooi.com/2011/08/22/how-to-improve-samsung-galaxy-s2-battery-life/
Hi Jayce,
I rooted my samsung galaxy s2 using CF root..
after that i loaded into CWM recovery mode but it shows E:failed to verify whole-life signature. E:signature verification failed..
FYI before this i installed ROM MANAGER and realised it wasnt compatible with CWM MANAGER so i uninstalled it..
My phone did load into clockwork mod recovery before but now no longer..it just enters into android recovery system 3e whenever i trying to get into recovery mode..
for now i cant restore my previous backup using Clockwork mod recovery and of course not to flash a new rom…
hope that you can help..thank you very much..
warmest regards,
May
You installed ROM Manager after CF-Root?
Yes I did. So any advices for me? 🙂
Try to reinstall CF-Root again then.
Do I have to wipe data and cache?
Wipe them if can.
NEw to this, I’m trying to recover my stock rooted rom at first i was receiving a mismatch md5 error then i ran shell command now I’m I’m getting a system error while restoring system
Look like a bad backup copy. Try to restore another backup copy.
Hi, i have a doubt (it may sound stupid). While backing up ‘data’, the CWM also seems to be backing up the internal sd contents. It it true? So if I restore the backup, will it also restore the internal SD contents to the previous state?
No, CWM does not backup internal SD card content.
hi, can u help me please. i want to know how to unroot my galaxy s2 with the lightning rom 6.1 installed on it. and i also want to know how to reverse it to the original stock kernel without any data being deleated
No idea on unroot Lightning ROM.
Just install stock kernel with Odin will do.
Hello Jayce, i’m using cwm to regular backup my sgs2. the last 2 times i have backedup tmy phone, while i restore the backup i receive “unable to restore /system” and restore process is interrupted so i can only partially restore my previous backup, loosing time each time.
i have also tried backing up on internal and external sd, and also format /system before restore…no difference, same “problem”
Are you using CF-Root kernel?
i am using cfroot only to root my rom, then i use other kernel like siyah
Then it might be siyah kernel issue. Consult siyah kernel developer.
So, anyone with custom kernel might have problem during restore made with cf-root’s cwm?
is there alternative ways to flash directly siyah kernel and backit up?
thank you
Simone
Might be. I have no issue to restore CF-Root CWM v4 backup with CF-Root CWM v5.
Hi jayce!
I can’t seem to restore my initial back-up when I just rooted my phone and not yet installed a custom ROM. My CWM Manager is v3.0 and my ClockworkMod Recovery is v5.5.0.4 . My back-up file is located in the external_sd should I transfer it in the /sdcard? I’m running in Redpill Kernel 1.3 and also I tried the Siyah Kernel 2.6.12 but still I can’t restore my initial back-up.
Transfer it yourself manually. Else find an option in CWM 5 to restore from internal SD card.
Hi jayce!
I moved the back up file to the internal sd card and tried to restore it using CWM v5 and CWM Manager v3.0 but still won’t work. I also tried the advanced restore for boot, system, data, cache, sd-ext but all results shows “MD5 mismatch” in both Redpill kernel 1.3 and siyah kernel 2.6.12.
Do you think I have messed up the back up file before? Or have not backed it up properly? I checked the initial backed up file (when it was first rooted without custom rom installed) and what I noticed is that all are in “disk image file” not like the other custom rom back ups which have “TAR archive file”.
Thanks!
MD5 mismatch == corrupted backup.
I see. Thanks jayce!
Hey Jayce …….do i need to do any wipes before restoring???…….. Thnx

Hi, my s2 is spoilt and i’m sending it for repair. But i want to back up my contacts and my apps, and my calendar which is linked to gmail, but i’m kind of a IT noob. Do i have to back up using this clockworkmod thing or is it in play store when everything resets? I seriously have no idea, i just connect the phone to my computer and transfer everything to my computer. Do you have any idea what i should do? I don’t want all my apps and data to be gone 🙁
Hi Myuki, please refer to this guide.

No, CWM restore everything – the full system with data.

Hi resul, ask the person who repaired it.
hi jayce
once restored …..would i have to back up my system again or it will remain backed up..?
the link you gave for galaxy note 2 gallery…well i installed it through cwm but nothing happened….should i try the link you gave for sgs 3 ?? any ideas ( sorry for asking this question here ).
i have backed up on ext sd card….still back up was in the folder clockworkmode in int sd…is it ok ?
It should stay in the place that you backup previously.
Sorry, not sure which one are you taking about. Better ask at that post.
Yes, you can have ClockworkMod folder on both internal and external storage.
