I recently got a friend's GS2 (i9100T) which has stock JB 4.1.2 on it.
The friend has no idea what other roms and versions were installed on the device.
He wants me to root, install recovery and a custom rom (like CM or AOKP).
I've heard that depending on whether or not 4.0.4 was installed at some point on the phone, I could brick it if i wipe data in CWM during the above process. What precautions should I take to make sure I don't brick it?
(again, currently installed jb 4.1.2, I want to root, install recovery and then flash a custom rom).
Thanks
First of all take a nandroid backup (search around xda)
To root your device go Here read instruction, download philz same as your device model (PhilZ-cwm6 v5.06.1 with CWM 6.0.3.2 based recovery (i9100T))
flash via stock recovery.

1. Do I have to root before I flash this kernel/recovery or will flashing it make me rooted anyway?
2. I assume that after installing this kernel/recovery I can then flash whatever ROM I want (in CWM) and safely do wipe?
Thanks

You are going to root your device right? so flash via recovery (Volume up + Home + Power)
after flashing this kernel your device have CWM recovery and superuser,
Yes you can flash costom rom that is compatible with your device model (i9100T).

Great, thanks. I don't really care about rooting at this point, all I wanted was to (safely) get the phone to have CWM+non-dangerous-kernel so I can easily flash CM or AOKP (which are default-rooted anyway).
You've been helpful, thank you.
You say you're on 4.1.2 now? Don't stress at all about the brickbug. It only affects ICS 4.0.4 with the stock kernel (or any kernel which hasn't disabled mmc_cap_erase). So you're not brickbug susceptible at all. Only if you're on 4.0.4 do you need to worry about it. Doesn't matter if that's been on there in the past, if it's not on there currently, it can't affect you.

Yes,, you need to flash a custom kernel.
1. First post your full ROM details
2. Can you confirm that you have ROOT access?
3. If your USB is buggy, you still flash Siyah kernel using mobile Odin, or the temporary CWM recovery. Root access is needed.
Thanks for the really fast reply.

1. Stock 4.0.4 from samsung; Kernel version 3.0.15-I9100XWLPT-CL941023
2. 100% have root access. Running Droidwall (which is working) among other things
3. I'm unsure if it's the phone, USB port or drivers which are buggy.
Is it possible to get a definitive procedure to flashing Siyah with mobile Odin? (presuming it's safe to do so). After that, is it safe to just flash the full CM9 ROM with CWM?
The safest way to avoid the emmc bug is to flash a custom kernel. Like siyah or dorimanx. If you have root access, and CWM, you can install one of them. Do you have CWM? well then follow these steps.
-Download a custom kernel. Eg the .ZIP file of the latest version of siyah kernel for S2 from gokhanmoral's site.
-Store it in your internal SD card on your phone.
-Boot into recovery. ( Vol-up + Home + Power button )
-Go to: install zip from SD -> install zip from internal SD
-select the kernel's zip file
-select 'yes'
Let the phone reboot once your done. You should have a custom kernel and no chance of the emmc bug bricking your phone.
The reason I suggest using CWM rather than Odin, is incase you have a faulty usb port, that might pose a problem while installing via Odin.
Hope this helps.

I have root access but no CWM. When I originally rooted the phone the sole reason was for droidwall.
Is it safe to install CWM and flash a custom kernel as long as I don't do any data wipes?
Can I install a custom kernel and have the phone as is (without noticeable differences) until I flash a custom ROM?
What happens to SuperSU and it's settings when I flash a custom kernel (and will I still have root access)?
Finally, if anything screws up what is the recovery procedure? I don't have a copy of this kernel/firmware as I installed it as an OTA update.

You can make a nandroid backup with cwm. That will create an image of the current state of your phone to restore incase necessary. Just make sure u have a custom kernel and follow steps mentioned in the guides on this site and you shouldn't need to worry

I've installed Mobile Odin (v3.35)
I've installed FlashKernel (v2), there was a v1 higher up the page but I'm going to assume that v2 has some bug fixes or other updates (please correct me if I should be using FlashKernel-I9100-v1 rather than v2.
Now, I'm not sure where to go: Should I install CWM or flash straight to Siyah kernel. CWM seems safer since I can do a backup and hopefully have some access if anything goes wrong.
How do I flash CWM with Mobile Odin? Which flash (mode? partition? not sure about terminology here) do I choose (Kernel, ..., etc) and probably importantly: which version of CWM should I be using? I've seen many threads talking about CWM4/5/6. Are they simply updated versions? designed for different kernels/android versions? Are there any specific versions which try to mitigate the superbrick bug?

Flash Siyah kernel straight using mobile Odin. It comes with a permanent CWM recovery too.
Todays almost all kenels are safe
so resure yourself
And be careful, when you flash rom in recoverymod
if. battery is off when flash rom, your device have hard brick
so you must have change your main board

Siyah kernel flashed and working perfectly. Didn't realise how instant it would be. Thanks again to everyone, this community is friendly and helpful.
I'm just wondering as I'm in the same boat as the OP was once in.
When it comes to choosing the Kernel does it matter if its JB based or ICS because I'm on the stock ICS rom.

You don't have root access, right? Flash a custom kernel with Odin (like Siyah), but make sure it's compatible with your firmware. So if you're flashing Siyah, flash the version (v4 and/or v5 is what I thought) that's meant for ICS, otherwise your phone won't work.
Sent from the Matrix
Actually I used another method that allowed me to gain root access, but I'm on stock kernel and rom. I kind of feel safer when flashing a kernel and rom from recovery.
So say I use Siyah ICS for my Stock ICS rom, If I wanted to flash a JB rom like the one leaked from samsung would I need to also flash the Siyah kernel for JB too?
I have I9100T as well and 4.0.4 on it, what do I do? Will Siyah work for me?

1. Download any version of CWM from here
2. Get desired rom (kernel too if you want)
3. Place everything in Externel SDcard
4. Boot into stock recovery (Power+Home+Vol up)
5. Use stock recovery to flash CWM
6. Backup Current stock rom
7. Wipe the usual
8. Flash Custom rom (Or just kernel)
9. Reboot
10. ?? Profit ??
Now you got Custom rom or Kernel + Full stock rom backup (can always get stock rom from sammobile if you lose it)

Thank u for the response. But im a bit scared flash or wipe in temp touch recovery. Because a friend of mine got his s2 super bricked while trying to flash on stock 4.04 kernel. does this emcc bug affect 4.03 stock kernels as well? So can i just flash the latest Siyah Kernel using ODIN ??
Any time you root/flash a Rom theres a chance to brick your phone. What -Grift- said is the easiest and best way to flash a custom Rom in my opinion. Just make a Nandroid backup, delete data and cache, install the zip file from your SD card. I've flashed 4 Roms so far with this phone, all successfully. Currently I'm running Cyanogenmod 7 on my DINC 2. Good luck on whatever method you choose.

Go into download mode, connect your phone to your computer and use Odin to flash a custom kernel to your phone. That done, you have root and you're safe from the emmc superbug. (EDIT: although 4.0.3 doesnt have the bug, if thats what is bothering you) You can then flash a custom rom or whatever else you please. Use the TAR version of siyah v4.1.5 from www.gokhanmoral.com
Instructions on how to use Odin are available all over this site and on the web in general. Search and you'll get it.
If you don't wanna use Odin, your only other option is flashing temporary CWM. Search for rachmat3's method or use the one mentioned above. All three are equally safe provided you read up on the procedure adequately.
99.9% of the phones getting bricked is coz people jump headlong into the procedure without first bothering to educate themselves on how to go about it. They get what they deserve.

If noobs on xda have taught me one thing, its that smartphones just aren't for everyone.
Or just wipe only when you have flash the rom (custom recoveries are safe e.g siyah dorimanx)
Edit: AFAIK 4.0.3 are safe the bug is with leaked 4.0.4?

Thank you for the info. I know few things about rooting and custom roms. I have flashed so moany roms with my HTC. Im new to samsung and odin. Thats why i wanted to make sure before doing anything stupid.
Thank u all for the help. I successfuly flashed Siyah kernel to get root and CWM
Sorry for the noob question, but i really need some assurance before i proceed
My goal is to install CM10 for S2.
So in order to do that i need to:
1. Download ClockworkMod Recovery 5.5.0.4 and flash the kernal via odin
2. Download SuperOneClick to Root my S2
3. Proceed with CM10 flash -> then Factory reset.
So that's about it right? backup has been done. anything else i need? What about modem?
So pointer would be great. I'm kinda rusty, left the android scene for years.
PS - My S2 is stock, no mods.

Quite right.
You need CWM recovery to flash CM10.
The easiest way to get it IMO is to flash a rooted kernel which contains CWM recovery.
You can use SiyahKernel or PhilZ-cwm6 kernel ... it's your choice and depends on your current ROM version.
After flashing the kernel, your phone will be rooted and you will have CWM recovery.
You should create a nandroid backup in CWM recovery - just to have a complete system backup of your current ROM.
Then you can flash the CM10 in CWM recovery - stick to the installation instructions of the ROM. You may have to wipe data/do a factory reset.
Good luck !
So if i were to use PhilZ-cwm6, i dont have to use superoneclickroot? Correct?
- so no need for odin right?
About choosing PhilZ kernel, mine is XWLP7, so, i would download XWLPZ kernel? Correct?
im nearly getting it LOL.
You don't need superoneclickroot when using PhilZ-cwm6, it's already rooted.
Go to http://forum.xda-developers.com/showthread.php?t=1877270 and search for XWLP7 and download that kernel (I'm not sure XWLPZ is close enough in version, but as there is a XWLP7 kernel there, I would use that.)
superoneclick is obselete. If you have CWM then theres no need for Odin. You get CWM with almost all rooted Kernels. If you aren't currently rooted however, you wont have CWM. Imo, the best way to go from no root > root is to flash a rooted Kernel via Odin, and yes your kernel version should correspond to your ROM version.

Stock recovery DOES NOT include flashing through zips so even if you in fact can flash stock recovery through CWM you CAN NOT flash CWM through stock one.
And to be honest I can't see any reason why you'd like to do so.

i don't think that is possible! how could you enter a custom recovery through a stock ones?!
Its called fake flash and was invented by koushik Dutta and Paul O'Brien. I used it on my HTC desire for a while. You essentially flashed it into memory and was gone on a reboot. This method is pretty old hat now. Im not convinced anyone uses this anymore. It's certainly not available on the S3.
Actually earlier rooting methods of desire gave you a leaked engineering version of the recovery that had no signature verification. That's the only reason it was possible
Sent from my GT-I9300 using Tapatalk 4
you could try something similiar, for example mobile odin, there you can flash update.zips and keep your stock recovery. (but it has no other cwm abilities)
or you use syah or googy-max kernel, where you can boot from stweaks into 2nd rom utilities which is a full working cwm and disappeares after reboot. there you can keep as well your stock recovery (but you have to flash a custom kernel )

Thanks. I guess that is the OP's solution then!
maybe anpother suggestion, which i often use could be the app online nandroid backup (its on the market), which can perform nandroid backups whithout going into recovery.
So there is no need of a custom recovery as long as you do not want to restore your backup.
and in combination with mobile odin you can flash update.zips. so the basic cwm abilities are covered (as long you have root)
Hi ,
I am currently having 4.1.2 official on my SGH-I777, recently rooted it and have mobile odin lite installed.
Need CWM recovery installed so that i can flash SuperNexus2 rom. So i have downloaded recovery-clockwork-6.0.1.0-i777.zip file from clockworkmod dot com website . Can i flash it directly from the stock recovery which i have now? or any other safe method you can suggest.
In some thread, there was a mention to flash boot.sys file from other kernel using Mobile odin which will get cwm installed.
If this is the way to go, please suggest a safe Kernal. I am just looking to get a stable daily driver for now, as i dont have an alternate phone.
Thanks in advance
the stock recovery isn't good for much, so no, it won't allow you to directly flash the cwm recovery.
Once you're rooted and have mobile odin (&the odin i777 kernel) installed, you're halfway there.

I think the nomswap version will allow you to boot to stock 4.1.2, but I can't promise that, I've never tried it. You should prepare as though you won't be able to return once you hit [flash firmware] from Mobile Odin. It's all covered in the guide.

Yes, if you use AJK v4.8 NoSwap you will be able to boot into your 4.1.2 system.
Also, if you are new to the I777, you should know that the recovery, including CWM recovery, is a part of the kernel, and not in a separate partition, so it can not be flashed separately from the kernel.
