Thanks again for help..so I can flash any rom..

[Galaxy S II Q&A, Help & Troubleshooting] BlurrOVO:
Ok, I'm having a nightmare in what I'm trying to do!:(:confused:

I'm currently on ICS, but this custom ROM:

http://xdaforums.com/showthread.php?t=1527861, requires that I have GB running. I'm finding it difficult reverting.

Do I need to flash a Kernal that is comptabible for GB and not ICS?

Also, my GSII is unbranded, which official, unbranded ROM do I download? I live in the UK, so I'm assuming it's the European one?

Anything would be grateful :)

In the custom ROM thread, I can only read that it needs GB bootloader ... or am I mistaken?!

Having a nightmare trying to root my phone. Followed all the instructions to no avail. It still won't give me root access.

Followed Cnet guide to rooting to a T

Got the insecure kernel

Got the .net framework and odin and s2root

Flashed to the insecure kernel that was provided on lyriquidperfection [sic] page and it still won't give me root access. Superuser app was installed but titanium backup and others say I don't have root priveledges despite S2root saying it's been successfully rooted.

Then I flashed back to the secure kernel and tried rooting by the chainfire method. That hasn't worked for me either. I've no idea what's going on with it. I don't know whether there is some kind of conflict between lyriquidperfection's rooting method and the chainfire root or what. I followed the instructions down to the letter.

---------- Post added at 04:09 PM ---------- Previous post was at 04:04 PM ----------

I've got the following if this helps

GS2 (UK) GT19100

ICS 4.0.3

I recommend to flash CF-Root kernel.

Use the XWLP7 version.

Maybe you will have to flash the stock kernel on your phone, and afterwards try to flash the CF-Root kernel.

Good luck !
[Galaxy S II Q&A, Help & Troubleshooting] tiincandroid:
I've tried flashing the kernel to

CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5

I believe that's by Chainfire.

It installed Superuser and CWM but still won't give me root access. It's really frustrating. Especially considering that the instructions were so simple and weren't complex at all.

Is there anyway that I can remove CWM and Superuser so that when I go to reflash it has to install them again. Maybe that's what's causing the error. I did briefly get it working once, but cocked it up by trying to use S2root over the Chainfire method. Now I get the feeling that the two methods used together are causing some kind of conflict.
[Galaxy S II Q&A, Help & Troubleshooting] It_ler:
As I wrote before:

Flash the stock kernel for your ROM (=> that will unroot your phone and remove CWM recovery).

Then flash CF-Root kernel again.

Have a look into Intratech's Official Firmware thread to find the stock kernel => http://xdaforums.com/showthread.php?t=1075278
[Galaxy S II Q&A, Help & Troubleshooting] tiincandroid:
So I flashed to the stock kernel and then back to Chainfire's using the page that you recommended.

Still no root access. It's a real pain in the ass now.

Any ideas?

Should I disable anti-virus on the phone.

I don't really understand what the issue is. Would flashing the firmwear help restore things back to how it should be?
[Galaxy S II Q&A, Help & Troubleshooting] It_ler:
Just try it.

Flash the whole stock ROM and do a factory reset/wipe data in recovery mode after flashing it.

Then try to flash CF-Root kernel again.

You flashed an GB kernel on an ICS ROM.

Not a good idea.

Please flash an ICS kernel to the phone to get it work again.

If you don't know the exact ROM version, just use latest SpeedMod K3-25 kernel => http://xdaforums.com/showthread.php?t=1574218

But you can also flash another "universal" kernel (such as Siyah v3.3.3) ... as long as it is for ICS.

If your phone can boot normally, you can check the exact ROM/PDA/Build version number and search for another kernel, which is specific for your ROM (such as CF-Root).

Or just stay on SpeedMod/Siyah kernel, as they both are rooted, stable, smooth and will work fine on your phone.

[Galaxy S II Q&A, Help & Troubleshooting] It_ler:
There are significant differences in ICS ROM versions.

Most issue can be solved by wiping cache (and Dalvik cache) in recovery.

Just try it.

Shut down the phone, press Volume UP + Home + Power until recovery menu appears, select wipe cache (and in CWM recovery Advanced > wipe Dalvik cache), then reboot.

If this doesn't help, you may have to do a factory reset / wipe data ... or just flash another ICS ROM version.

CWM = ClockWorkMod

For our phones, the recovery mode is included in the kernel.

So, when you want another recovery mode, you will have to flash another kernel, which contains the recovery mode you want.

Stock kernel has the stock recovery.

There you don't have many options (no wipe Dalvik cache, no backup/restore, no fix permission, no install zip, etc.).

Those extended option are part of the CWM recovery, which is contained in most custom kernels, such as Siyah, CF-Root, SpeedMod, etc.

To find the corresponding CF-Root kernel for your ROM, have a look at your Build/kernel version number.

Or dial *#1234# into your phone and look at PDA.

Then download and flash the CF-Root kernel for this version ... and your phone will be root, you will have CWM recovery and CWM Manager app for easy usage of some CWM recovery options.

Edit: Now for a question. Another thread on here suggested changing /efs/imei/mps_code.dat to contain "XEO"(w/o quotes) to solve the problem. My file contains "NEE"(also w/o quotes). Don't XEO and NEE have something to do with the firmware region/version? Is it safe to change? I currently have CM9.

Either Google enabled Navigation in Finland, or CM9 has some modded version by default. Because today I was able to use it, which I've never done before.

I have less time. But not every kernel is suitable for each rom. Take Siyah as first base. Then flash a suitable kernel for the rom you want to flash and reboot to recovery. Then you can flash the rom you have chosen.

im just curious though.. despite flashing all stock ICS and GB ROMs the phone was still bootlooping .. most of the posts ive read would say once you go all stock then phone is OK.. someone told me i may not have a regular soft brick issue and could have issues with phone memory.. they say that odin writes on the 1st gig of the phone memory and if that part is a bad sector my phone won't boot with any rom's stock or custom.. suggestions say i may need to repartition phone and try to write on the 2nd gig.
[Galaxy S II Q&A, Help & Troubleshooting] albertholl:
First, assume that you don't have a hard brick.

Put Siyah kernel on your phone with Odin.

After reboot (also when you get a bootloop), get you battery out.

Then put the battery back.

Go to recovery with 3-buttons.

From there go to advance.

There you choose reboot to recovery. Execute that.

If you phone does reboot to recovery, then thats good.

Now...

If you already have downloaded a rom, read the thread of this rom and look witch kernel is been advised.

Download this kernel.

Also download this script.

This script "super wipe script by biftor" cleanse your phone.

If not go to recovery and go to mounts and storage.

Put your USB cable in your phone and in your computer.

Then go to mount USB storage and execute that.

I everything is alright then you can see tbe USB storage of your phone on your computer.

Copy the kernel and rom you have downloaded to your Internal SDcard.

Wait untill it's ready.

Exit mount USB storage and remove the USB cable.

Go back to the beginning of CWM.

Choose Install zip and "Choose zip from Internal sdcard.

Flash super wipe script by biftor and wait until it's ready.

Then you can flasf the kenel you have downloaded.

If thats done you can reboot in recovery.

Your are now running your downloaded kernel .

You can now flash the rom you have downloaded.

Reboot.
