No need to flash cf root before update to ics

Just update to ics and then flash cf-root.

If you flash cf root in odin, you vet Yellow Triangle, but easy to remove with CF TriangleAway.

If you only need root and none of cf-root add-on features, root following link in my signature. Easy and no Triangle

There is also a thread to flash cf-root in recovery without odin. Look for it in dev section
[Galaxy S II Original Android Development] galaxys2s:
so wat i do first is to update to ics throuh ota

can i flash cwm 6 touch on stock ics

n make nandroid ??

after dis wat will u suggest me to flash to get root wid cwm 6 on stock ics ??

n also for unroot too ?
[Galaxy S II Original Android Development] It_ler:
I recommend to flah CWM and create a nandroid backup first.

So you will be able to restore your current system, if you want or have to.

Then update via OTA or just flash the ROM you want, root and be happy.

Good luck !

Hey guys I have the Bell Canada SGS2 using version of the 9100M; baseband is MUGLD3. What cf kernel would anyone recommend?
[Galaxy S II Original Android Development] It_ler:
Baseband is not important to find the correct CF-Root kernel.

Please post your Build number/kernel version. Have you got ICS (Android 4.0.3) or GB (2.3.x)?

Or dial *'1234# into your phone and have a look at "PDA".

This should lead you to the corresponding CF-Root kernel.

[Galaxy S II Original Android Development] It_ler:
You can try to flash CF-Root-SGS2_XW_KPN_LP9-v5.4-CWM5.zip, as XWLP9 is also Android 4.0.3 and it was released in the same month as your ROM.

Backup everything before flashing ... just n case.

As you don't talk about any other change, I assume that the "unsafe" stock kernel is untouched in this CF-Root kernel and the risk of the brick-bug is still existing.

Is the contained CWM recovery "safe"?

Ok, so my i1900 was on I9100DXLPB running ICS 4.0.3, never rooted before so I flash this file using Odin : CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER.zip to root. It showed pass on the Odin screen, the phone went to the bootscreen with the triangle warning logo there, then a black screen. I could go to download mode (thankfully), and flashed another kernel ( siyah 4.1.4) and phone rebooted and went perfectly fine. But I don't get why my phone got stuck on black screen when everything went perfectly fine; even Odin showed a pass so what exactly went wrong?
[Galaxy S II Original Android Development] It_ler:
Maybe wrong CF-Root kernel or some Kies processes were still running on your PC while flashing?!

[Galaxy S II Original Android Development] TTRpwnage:
I'm guessing it's probably the latter. I went into Rom manager and was notified that I didn't have CWM Recovery installed so does this means only CF kernels can access to CWM recovery?

MUG LD3 CF-Root

Chainfire or TWIMC

Will/can you create a CF-Root based on Canada's kernel, MUG LD3? (SGS2 ICS 4.0.3) I've read a lot of topics lately but don't see any solution for issues I noticed after rooting my phone. It was working prior.

- Can't install some apps from market, USB, or SD card. (Reason seems to be due to mismatched kernel not LD3.) Work around for most apps is to remove SD card, install app, and then add sd card again but at no time can you install to SD card.

- Yellow triangle. Goes away with Triangle Away or following shell steps to fix.

- Unable to encrypt phone while SD card is attached. Works if you remove the SD card, unsure if this was an issue before flashing.

I'd also like to ask if I have the following correct;

If I extract the I9100MUGLD3_I9100MBMCLD3_I9100MXXLD3_HOME.tar.md5 in linux, and then the zimage file, and put the zimage file in a new tar can I use that to flash back to stock and keep the root? (But lose the CWM you have added.) And then install a/the CWM apk?

The issue with the apk's not installing even from google play is really getting to be a problem and I'm having space issues. I'm hoping that my above questions and your answers might help resolve it for me and anyone else who's noticed this.

TIA

Won't boot after root

Hi All,

I think I've double tapped the USB debugging meaning that debugging was not enabled before rooting the phone. I then flashed the phone with odin which says it worked apart from the big yellow triangle and not booting. I've ditched the battery out and retried another 2 times with the same result. Any ideas?

[Galaxy S II Original Android Development] It_ler:
To confirm if you have flashed the correct CF-Root kernel, we must know the kernel/ROM version of your phone.

Have a look at menu Settings > Phone information > Kernel / Buid version number.

Or dial *#1234# into your phone and post the output for PDA here.

If flashing CF-Root kernel does not work at all, you can try to flash another (rooted) kernel, such as SpeedMod or SiyahKernel.

And you are sure that you've got the interational version of the SGS2 (GT-I9100)?!

Is replacing the Kernel via Odin not enough? (and then a new ROM)

Most custom ROMs are provided as CWM flashable zip files.

Stick to the installation description of the ROM and flash the custom ROM as zip file in CWM recovery.

You may have to wipe data (do a factory reset) before flashing the custom ROM ... should be in the installation steps for the ROM.

[Galaxy S II Original Android Development] Phil3759:
Sadly, I meant once you get a new phone. That one is dead
[Galaxy S II Original Android Development] Chainfire:
If the kernel has patched MMC_CAP_ERASE, it is 100% safe. CWM6 is not more or less safe than my CWM5 (my CWM5 also has MMC_CAP_ERASE patched). The only difference is that an update.zip can still cause a brick if the format command is issued in the update.zip, this is regardless of CWM version.

CF-Root is vulnerable only to the update.zip format command (why would anybody still use that? when it's known to brick devices? it goes beyond my comprehension)...

I'm not sure which kernel revision brings the actual fix from Samsung - I do know their current (internal?) sources have the issue fixed.
[Galaxy S II Original Android Development] Phil3759:
Thanks for the clarification. Entropy said once the cwm 5.x versions are affected and only fixed in 6.x, from there comes my doubt. But I guess your custom cwm is patched compared to Koush 5.x !

By patched kernel is not 100% safe, I mean, there's still a little chance the patched bytes get confused with another sequence. If by chance it still boots, it will be a buggy kernel, yet not patched... Recompiling from source after disabling the MMC_CAP_ERASE zero'es this very little risk, as I understand it

Also, what you say means we can still brick in 3e recovery if the signed update.zip has a format command? I was not aware of this risk in stock 3e

Any yes, so many custom ROMs still come with wipe and format commands in the updater-script
