Hey guys.
I have litening rom v2.1 ICS on my GS2. I have been having several issues with it. Such as super battery drain when connecting to 3g. I have tried ununstalling some apps but the drain seems randomised. I have installed better battery stats but it doesn't really find anything of interest. I am getting the old ANDROID OS drain. Although i do really like ICS, If i want to go back to the old GB nandroid backup what steps need to be taken.
1. From what i have read is flash a stock rom first. Does this rom need to be a 3 file rom or can i use the vodafone stock rom which is all of the 3 combined into one file "GT-I9100T_VAU_I9100TDUKF4_I9100TDUKF4_I9100TVAUKF4" is the stock rom i have on file. If i need a 3 file can someone link me up a stock 3 file gb rom? Do i need to flash a GB bootloader first? Do i need to add a PIT file when flashing the stock rom?
2. Do i wipe the phone after installation or before. I heard it's back to wipe the phone before going ICS -> GB
3. After flashing stock i assume i need to cf-root the phone again then i can restore a nandroid backup is this correct?
Alternatively is anyone on a ICS rom that is stable? Which rom is it? Hows the process from litening to a different rom? Just a wipe then flash? Thanks guys.

Hi,
Can anybody tell me if i root my s2 (currently on KF3 firmware) with cf method and flash stock kernel,will i be able to install new ROMS like litening etc,how ?, and will i be able to come back to my stock firmware and kernel,and how ?
thanks in advance !
You can flash any Custom firmware anytime, without root. And you can go back to Stock firmware and kernel anytime.
Regards.
so if i root(by a method you earlier told me),can i also use any rom on that ?if yes then how and also can you please tell me how to come back to stock rom(before flashing with custom rom) state ?
You just need to add the .tar file of the Custom firmware in PDA section of Odin and flash, same for Stock ROM.
Regards.
you can root your phone as ihappy said but use the threads on the forums to find the stock kernels and roms that suit you. and i mean by what region you at. most of the custom roms come with root anyway so i would not worry about rooting. the thing is though whenever you do flash always make backup. first time i flashed i did not do backup and i was panicking on how to go back to stock.but thankfully the guys in this community are the best around and helped me out. hope my post helped in anyway
Hi everybody. Im coming from a DroidX and now i bought this piece of art, the Galaxy S2.
I have a question, if i install Cyanogenmod ROM and then i want to install a MIUI or another rom, do i need to use the Odin software for wipe al the content in my device or just flash like normal in clockwork?
My question for this is because in the DroidX if i want to change the ROM from froyo to gingerbread in a custom rom, i need to SBF.
Thanks in advance.
you can wipe in clockward recovery and install it no problem
just keep a nandroid back up incase something goes wrong
if you want to flash a CM7 based rom like miui or galnetmiui just do it as if you were upgrading from an older version o CM7, but if you want to flash a samsung stock based rom you have to use odin and then flash it
Thanks A loooot guys!!! YOU ROOOKS!
You need to wipe using the custom recovery and then install the zip from the recovery to .
Hi,
Apologies in advance for what is probably a very obvious question for those that know. I'm two days into my rooting experience and currently I have rooted my SG3 and then also installed the Omega v13 ROM. I haven't done anything with the kernel up to now.
My question is - when the official JB release happens (hopefully tomorrow) and I want to upgrade to it and then also install the new Omega v16 ROM, do I:
a) wipe everything, install the Samsung Official JB firmware and then install the Omega ROM again on top of it, OR
b) do I just wipe everything and install the Omega ROM directly.
I'm a little unsure of the difference between the firmware and the ROM (unless they're the same thing). Does the Omega ROM contain the actual firmware or is this a separate thing?
Any advice appreciated.
Thanks,
Adam.

Rom is usually the firmware but custom rom may not include the modem .
Uses existing modem .
You will need to root your phone before installing Omega or any custom rom .
Best is to wait for Omega build after the full release of JB then just flash that over current .
JB will not be released to all and sundry on day one it will start the rollout on day one and gradually work its way eventually to all phones .

Thanks jje. As I have already rooted and then installed a custom ROM over the official firmware, I thought it might be "better/cleaner" to do it from fresh. I have not great battery performance and still some redraw issues so I thought starting from scratch might be advisable. I would rather not though - I haven't' tried a restore from Titanium yet and not certain if it will recreate all my apps/widgets including their positions and data.
I'll wait for the release and then figure it out.
Adam.
Agree once JB is released and i decide on a rom it will be with a total wipe .
TB will create all apps but not layouts or folders organization .
A workaround is to install rom boot to recovery mounts and storage and format data .
Then go to your ICS Nandriod backup and advance restore data only will bring back layouts .
But you may find some apps FC or fail to open .

I am still new at this stuff, and did research on the forums, but cant find an answer
For example, one of the Roms I want to install had this description;
(http://forum.xda-developers.com/showthread.php?t=2133763)
YOU MUST BE ON THE VERIZON (USA) JB KERNEL(either through dualboot or the leak) TO FLASH THIS ROM
YOU MUST FOLLOW THESE INSTRUCTIONS EXACTLY.
~~~~
I am using Safetrap 3.11, and my stock rom is running just the regular stock that came with the phone (4.0.4) android
(My phone is CDMA too I think.).
Does that mean I have to install a different rom that has a JB kernel on slot 1, and then I can install this rom into slot 2,
does it work like that? It can get a little iffy for me trying to understand rom requirements.

No,you just install JB kernel and then Jb rom on system 2 (if you want) and you´ll still have ICS on system 1.
Be sure that before anything,you do a backup of kernel and cid,so you can go back to ICS if you want.
Here is the very good rom http://forum.xda-developers.com/showthread.php?t=2142593 ,everything is working,good battery life...
Just follow the instructions
Hi,
I have an i9300, stock ROM version 4.1.2 and baseband i9300xxema5 w/ custom kernal 3.0.31-Siyah-1.9.1+.
When I try to upgrade, it says my system has been modified.
What steps should I take in upgrading? Bear in mind that I want to keep all my files intact.
Should I begin by finding the stock kernal? Would that work? or should I find a stock 4.4 rom and flash it? But then, I'd lose my files. I don't want that. .-.
You have to install stock ROM via Odin.
