You can flash whatever rom you like over your existing rom. But follow the instructions for the rom you're going to flash to the letter; for example if it says to do a factory reset, do a factory reset, etc, etc.

root with flahing C-F root : http://forum.xda-developers.com/showthread.php?t=1103399
then from CWM recovery you can flash...

Ok so i dont need to flash 4.0.3 XWLP4 stock firmware using odin ?
My android XXLP2 version has already rooted wif cf root .
Now i jus follow the instructions ?
Thanks again.

Done all of that backup . But im afraid i'll get wierd thing like kernel panic mode .
Why would that happen ?
Sent from my GT-I9100 using xda premium

I had massive problems first time when i flashed, if you hit any bumps and cant start the phone after flashing, what i did was i flashed stock and then siyah kernel, put files on phone, boot to recovery and clear all data before flashing, that did the trick for my first flash
Hope you have a good time flashing and playing with your phone !

Best rooting method for stock 2.3.5.?

Hello,
Apparently, upd_1.zip method doesn't work, and SuperOneClick 2.3.3 can't root stock 2.3.5.
How can I root my Ace?
What's the error you are getting?
Is it something like status 7?
I also encountered similar issue.
1st time stock ROM root is OK. After roll back from custom ROM to same stock ROM, I got this error!
Try to wipe cache, format etc .. It works for me!
yeh I had that problem for like 5 weeks trying to root my ace but it had no root access !
OK so download cf-root b3
and flash with cwm 4
then just flash a different rom !
that simple
now I have root and a custom from!!!

I'm not getting any error, I read about experiences with both these tools and I'm pretty sure they can't root the device with stock 2.3.5. firmware. I want to know if anyone had success in rooting 2.3.5. and what tools had been used.

I don't want to flash a new firmware or a new recovery. I just want to root my phone so that I can remove some pre-installed applications.

Stock 2.3.5 ? I rooted it using the upd_1.zip file. Worked for me. Try the file posted in 'ZIP file to root ace" in this section. It might help.

Updated my brand new galaxy two days ago. Had no problems and was locked to the three network.
Used stock recovery to flash cwm v4 and then used this to apply the root update zip.
I am now running nimms amazing cm 7.2 rom and have had no problems.

no need to flash the firmware through odin..
go to cwm recovery.. wipe cache, wipe dalvik cache and factory reset(if you like) and flash it through the recovery!

the recovery you have is the stock recovery.. and for flashing roms and stuff you require cloxkworkmod recovery!
so i would have to ask are you rooted?! if yes then how did you root your device..?
ill guide you from there!

Start reading on how to root and installing kernel with CWM Recovery. SGS kernel and recovery parttions are the same.
Easiest way is flash Chainfire's CF-Root kernel with Odin here: http://forum.xda-developers.com/showthread.php?t=1103399
There are many other ways; Intratech has a quick root guide in post #1 here: http://forum.xda-developers.com/showthread.php?t=1075278
Read, read and read some more until your confident to do it. Otherwise don't.
Please also read the "Stickies" in each forum and FAQ etc and search for answers BEFORE posting.
Best of luck
And if you really want to try ice cream sandwich, i will advice you to go with cm9 first as it delivers the smoothest of the experience with almost no force closes or random reboots. You arr aware of the fact that you are going to flash an expermental build right. Its not stable for daily use yet.

XWLP7 is ics 4.0.3 which does not have the emmc bug, you will have no problem using CWM recovery to wipe data from your device before and after installation using odin.
Only firmware with 4.0.4 version is effected with the bug.

yes u can flash the same without any issues , since the EMMC bug is only with the leaked 4.0.4 firmwares.
also u can google for some youtube video tutorial on using 'ODIN' to flash a rom and follow the instruction carefully for a successfull flash

[Q] Root failed. please help

Hi all,
i am using sgs2 ics 4.0.3. I tried to root my phone using Odin and CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5.tar file. But it failed. I tried again but result was same. I have xwlp7 kernel version and latest Samsung kies installed in my computer. Can anyone explain what could be the reason? And what should i do to root my phone. Please help.
You could try flashing a custom kernel like siyah or dorimanx or use this method:

hi Haxtreme, the alternative method you suggested, didn't work. But flashing siyah kernel did it. Thanks to you. But suggest me what is the next step after rooting my phone. i have taken a back up of rom using cwm. i am a new root user.
Next step should be efs backup.
The next step!
You got root and CWM!
The next step!
Install custom ROMszZ
The next step!
Install custom kernels!
The next step!
Overclock/underclock! As you desire!
Backup apps with titanium backup!
Backup using nandroid!

If u wish to start something w/ odin (just use odin3 v1.85 for s2) then first time u must do is uninstalling kies as it's messed over both..
Then If u have stock rom zip, start flashing it again by ticking one packages & tick & browse pda to matched zip stock. Stay away from another option in odin then. If it's successful, mean ur phone had a full wipe reset to stock factory (that's why u need backup like TiB).
At this point I think u can root by rahmat3 methods without any issues if u run it carefully as his per. No worries..

Upgrade GB

Can someone tell me the descriptions of upgrading samsung s2 2.3.4 jokh8 to ICS
Sent from my GT-I9100G using xda premium
1. make a back up of your current firmware
2. In recovery, do a wipe of the cache then go to advanced and wipe daavik cache.
3. Using odin flash the ics firmware you like.
this tutorial should help .

Will it erase all data?
Sent from my GT-I9100G using xda premium
You already made 2 threads about rooting.
So since you "need" to be on ics,you open up another thread about gb-ics.
Whats next,a thread about how to use odin,or a thread about cwm.Or how about a thread for flashing kernel,or a thread about a rom.Then a thread about "help phone bricked".
Do us all a favour and read you lazy git.

1. Root your phone by flashing a rooted kernel containing CWM recovery (e.g. SpeedMod for GB ROMs), if not already done.
2. Make a nandroid backup of your current GB system in CWM recovery. (So you can restore it if flashing does not work or you don't like the new ICS ROM and you want to go back to GB.)
3. Have a look here for the latest ICS stock ROMs => http://forum.xda-developers.com/showthread.php?t=1544487.
There is also a description in the first post how to flash the new stock ROM with Odin.
I recommend to flash a pre-rooted ICS stock ROM from here => http://forum.xda-developers.com/showthread.php?t=1608071.
Download the ROM, extract the zip file, put the tar/md5 file into PDA section of Odin and flash it to your phone. (Be sure that no Kies process is running on your PC while flashing.)
4. Once you are on ICS and rooted, you can install TriangleAway (=> http://forum.xda-developers.com/showthread.php?t=1494114&highlight=triangleaway) app to reset the flash counter if needed.
5. Be happy and enjoy the new ICS ROM.
Good luck !
