Hello, I'm going to buy another Galaxy S2 as it is perfect phone form my persnal needs. No comments, no laughs, it's just me.
My current phone runs stock 2.3.6, but what I want is to get another one but with 4.1.2 to check if my setup on 2.3.6 let me get as much long battery life on 4.1.2.
I got CWM backup of my current 2.3.6 system and first thing I will do to new 4.1.2 is to make CWM backup, too.
I read that these systems are writetn in phone memory in a different way, something aboout different partitions, etc, you know. So my question is: can I transfer and restore CWM backup from one to another (I read about IMEI issues after restoring backup from another phone).
Another question is: if I flash 4.1.2 via ODIN to my current phone and I don't like, do I have to install 2.3.6 via ODIN then restore CWM 2.3.6 backup or can I restore CWMbackup over 4.1.2?

IMEI issues shouldn't be a problem if both phones are the same varient (i9100, etc). Just make sure that the recovery supports the backup file. In most cases, it should work. But beware, older recoveries may not fully support backups from newer recoveries. With your other question, it really doesn't matter how you restore android 2.3.6.

Hello all XDA users,
Many apologies for the noobish questions, I am new to this forum and this is my first time posting. Although a first time smartphone owner, I decided to be brave and attempt to root and flash my phone, which worked fine under Gingerbread until I wanted to upgrade to ICS. I have a International GT-I9100 SGS2 purchased in Singapore. I rooted it by installing a custom kernel and flashed a new Lite'ning Rom V3.2 with Gingerbread.
In order to upgrade to ICS, I tried through KIES and the "Software Update" function to no avail. I then tried to do so manually but Odin would not complete the process with the original I9100XWLP3 rom I downloaded on this site. I left it running on my computer for 2 hours only to come back home with the progress incomplete.
My questions are:
1) I live in Taiwan now. My other friends who purchased their SGS2 locally here all have gotten ICS through KIES. Am I unable to do this because I purchased it from Singapore and must wait for the Singapore rom to be uploaded? Is there no way for me to flash to the local Taiwanese I9100ZSLPE rom?
2) How long does an ODIN flash take to complete? Should I be more patient and waited longer than 2 hours for it to finish?
3) Does KIES no longer recognize my phone because I rooted it? It always fails to download the driver whenever I plug in my phone. Do I need to unroot to an official ROM such as I9100XWLP3, and then download through KIES to get ICS, or is I9100XWLP3 already packed with ICS?
Again, many apologies if these questions are elementary in nature, and thanks in advance for the help. Attached you will find a picture of my phone's current firmware state.
[1) you must be on a stock rom as your friends had, since you have rooted and installed a custem rom, keis will not recognize your phone. you can flash it from ODIN also, if you really need official update from Kies, you want to flash the same stock ROM your friends had in their mobile at your region...
2) Maximum 5 minit, something wrong with your connection, it is strange finally you got installed after 2 hours waiting...
3) same answer as #1, + you dont need to unroot, mere rooting will not effect Keis update, XWLP3 is an ICS rom
Should I perform a full wipe before upgrading my rom?
Thanks for your response, all the way from Kuwait. I backed up most of my files via Titanium backup. Should I now perform a factory reset before upgrading to ICS? Wouldn't the factory reset also wipe out my Titanium backup, or is this somehow protected? Do I need to transport my backup to my pc first? I tried to backup via kies, but the driver issue prevented my phone from being recognized.

on which firmware are you currently?
it is always good idea to transport to PC your back-up, even wiping and factory reset will not touch your own stuffs on SD card, also while you are flashing a ROM from ODIN and CWM.
also take care when you restore your backup from tintanium, uncheck all the system data, it will mess up your phone, if you had made the backup from a GB Rom, install only user applications.
Your backed up data will be on the SD card a folder named Titanium backup, you only need to download the application titanium backup from market, after rooting your phone.
Edit : sorry I did not notice your picture uploaded, that means your attempt on ODIN did not do anythig and luckly it did not hurt phone too, I think your PC connection or driver is not proper....google more about usage of ODIN....

if you are already rooted, and CWM installed you can find plenty of custom ICS roms on I9100 develeopment threads
trouble upgrading from gb to ics
i am experiencing the same lack of completion at the odin step. will the ics rom provided work with a virgin mobile phone in australia also?
Hello I am from Argentina, desperately need help.
I rooted my SGSII ICS 4.0.3 phone with CF Root LPJ everything went as expected. Odines PASS! and all but when my phone reboots it just turns off after logo screen with triangle.
I can get into recovery and download mode but that is all.
What should I do?
Might commit suicide if there is no fix.
Flash stock rom.
You can find it at sammobile.com.

If you can get into recovery and download mode, you are only softbricked. It could be worse.
Please be more precise, I lack experience but I will understand.
Which stock ROM should I flash now?
Because I got a downloaded I9100UHLPS_I9100AROLP4_ARO but it is not LPJ.
I also managed to find Kernel_I9100XXLPJ at intratech. Would flashing this kernel fix it? Could it possibly mess my recovery mode and brick my phone?
Flash the same ROM again using Odin, do not flash the wrong kernel.
ARO is a good ROM, just flash it again, it will boot, then root with the cfroot for that ROM later.
What do you mean by the SAME rom? I got this problem flashing a CF-Root kernel not an entire ROM.
The ROM I had before was ICS 4.0.3 which I upgraded officially via Kies.
Should I flash ICS 4.0.3 UHLPS that is for my region? I9100UHLPS_I9100AROLP4_ARO
I'm pretty sure that's what Atifsh meant, yes.
Thank you all! Thanks given with the button for all!!!
I flashed stock ICS 4.0.3 for my country downloaded from sammobile.com and the phone recovered with no trouble! I got my soft bricked SGSII working again!
Is there anything I need to wipe now to make sure there is no crazy leftover from the CF-Root boot fail?
If it's working fine, then probably not. I mean, you could always backup your contacts, call logs, SMS, etc and your apps with Titanium, do a factory reset, and then restore contacts, call logs, sms and user apps/data only (do not restore system apps or data).
But if it's working fine now, I don't see the point.
I want you to do two things for me tho.
First, get kTool either from Google Play (it's free) or from Hellcat's thread on here. Then backup your EFS. Keep one copy on your external SD card in your phone, and keep another copy on your PC. Then I want you to do a Nandroid backup in CWRecovery.
That way if anything does ever go wrong, you should be able to recover/get up and running again easily without losing your stuff. For example, if your phone ever borked & you had to send it in for warranty service/replacement, you could restore that backup when you get your phone back/a new phone.
Do a backup at least once a week and certainly every single time before you flash a new kernel/rom or if you make major changes to your system.
I am afraid of doing anything with this phone now. First experience = soft brick.
Damn I almost die. Now I need to find a way to get out of this stock 4.0.3 ICS because it is ramming through my battery and is as slow as a potatoe.
4.0.4 is eMMC hard-brick possibly if I wipe after flashing.
Now I feel like an expert.
I also tried flashing cf root today and it softbricked my phone. Weird.... next time I try to root my phone, I wont be using cf root.
Which Kernel was yours? Leave it here logged for future brickers.
Mine was LPJ
Is this possible? The full details are I had my phone stolen, and got a new one with android 4.0.4 on it. I have on my computer a copy of my latest backup of my old cognition gingerbread rom. Can I just use CWM to recover to my old rom, or do i need to first downgrade to a gingerbread rom, and then recover?
Thankyou very much for assistance
Edit: Also, I don't actually want to use the old rom, I just need the contacts it saved, afterwards I'll wipe everything and install a clean ICS mod. In case there's any way of doing this without having to revert
You'll probably need to restore the backup with a version of CWM close to the one the backup was made with, you can often have problems restoring if you're using a CWM version a lot (say 12 mths or more) newer than the one you made the backup with.
So I'd probably go GB/with a rooted GB kernel first, restore the backup & go from there. I mean, it could work first try with an ICS kernel that's running a recent CWM build, but there's a fair chance it won't.
Edit - And be really careful with stock 4.0.4, don't do a wipe while you're running that.
Wow. I just... wow.
Ok, so I did the stupid thing and just tried to restore my old backup without doing proper downgrading first and it ended up soft bricking my machine, couldn't get recovery mode up, but I got into download mode. So I downloaded my country's stock gingerbread rom from samsung's site and flashed it with odin just to see what happens, and somehow my old rom was working again, and I have all my contacts and data. saved everything up to google, upgraded to ICS, import.
Everything went better than expected.
Thanks for the help
Told you Important thing is you managed to fix it yourself without asking silly questions in Q&A. Not many people seem to be able to do that these days.
Well done. I'm glad you got it sorted
Edit -You're welcome
is it possible to backup my current ROM and restore it to another phone? of the same make and model? current phone 4.2.2 sentinel ROM (AOSP/AOKP) other phone 4.0.4 (Cyanogenmod)
my worries are would it:
1. overwrite the EFS?
2. Would the ROM fall to work or boot as two different phones have two different hardware
if somebody had tested this let me know.
also is there a way to mount a ROM/run/test it on the pc like some sort of emulator??

Yes. You can restore a nandroid backup from one SGS2 to another. Make sure you use the same version of CWM to do the restore tho.
No, it can't overwrite the EFS/IMEI, which is a unique identifier for the device & 'baked' into the hardware (tho you can trash it with firmware gone bad). No, why would the rom fail to boot if it's the same model phone ? Many people here have restored a nandroid made with one S2 to another.
'Test' a rom on a PC ? Unlikely. Some developers use specially designed boards with the right hardware mounted onto the board, completely separate from a PC. You're overthinking this a little methinks.
As long as you restore the backup with the same version of CWM, you should be fine, so when you get the other phone, install the same rom/kernel you're currently running on this phone, restore the backup (backup your external SD separately), done.
Edit - This all assumes you're getting another I9100 (assuming you have one now), do not try to restore the backup to another SGS2 variant.
great !! thanks.... for the detailed info. I will try.
also with regards to the CWM recovery does it have to be the EXACT EXACT version?? like can't I restore a ROM which was backed up with CWM recovery 6 and restore it with CWM recovery version 5? our vice versa? both phones are on AOSP/AOKP ROMs so maybe their recoveries could be some what compatible??or ?? unlike if one was running on a Samsung base ROM and another on AOSP/AOKP?
Sent from my GT-I9100 using Tapatalk 2
There's a fair chance you'll have problems if you use a different version of CWM (especially if there's a big difference in versions), but it might work restoring a backup made with V6 to a phone with V5. Tho if it were me, I'd get it done right the first time/without headaches by using the exact same version.
cool I will do that.... thanks

Hi guys,
Can I perform downgrade simply by just restoring backup of 4.1.2, created with latest CWM?
Or do I need to do it via Odin?
I rather do it from backup to save my time on restoring phone with all apps and customisation...
Please could you advise?
Thank you
Yes, factory reset and format internal media before you restore. I did the exact same thing (back to 4.3) last night after trying 4.4 for an hour, too many things don't work in Kitkat.
Make sure your 4.1.2 was at least EMG4 or later to avoid efs problems.

Backup is the easiest thing to restore from as it replaces everything on your current rom including the rom itself. BUT i wouldnt advise that as it may cause IMEI problems encountered when downgrading from 4.3 to lower due to the format of the efs being changed(which is modem related). Your phone would no longer receive calls etc.
Ive personally experienced this by flashing a 4.1.2 rom over a 4.3. As for a restore i am very sure it will not cause a problem but it can. In any case you can backup your efs partition by various programs and then restore by nandroid. If any problem occurs then restore your efs partition or upgrade to 4.3 again and flash MG4 modem.
thanks a lot for your responses guys!
I have formated cache and dalvik, formated data and system and hit restore afterwards.
Worked a treat!
Downgraded to EMC2. No problems with IMEI or phone calls.
Everything works fine.
