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.

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.

If i flash boot.img extracted from AJK, will i be able to boot into the stock 4.1.2 which i already have, or should i directly start proceeding with CWM and the new ROM, just want to make sure before i start.
...side note warning... Do not use Rom Manager with the i777. If ya do u could possibly brick ur phone. There is a Stickied thread in this forum warning of this.
....no back to the regularly scheduled topic.

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.

Thanks, guys i was able to flash noswap and was able to boot up into existing 4.1.2
I I rooted my S2 I777 using Frameroot-1.4.2 and flashed via Odin CWM 5.0.2.3 then I flashed AoCP KitKat from from GalaxyS2Root.com and now my phone is in a loop entering in recovery mode.
I flashed the rom on CWM and when I asked to reboot the system it start reboot and enter in recovery mode again.
I tried to flash the official rom from AT&T with Android 2.3.4 and even after I flash this rom it doesn't stop to enter in recovery mode.
First thing to do: perform a wipe/data from within recovery.

It was done and still reboot in recovery.
I tried to install a stock rom via Odin 1,85 but I failed in all the tries then I tried via Odin 3.07 and it worked and I did a full wipe and rebooted the system and it got back to recovery mode then I did it again and it worked.
Now I'm using a stock Rom with Androind 4.2.1.
Before it works I've tried to install the stock Rom and it worked then I rooted the phone and installed CWM and it always reboot in recovery mode.

This part makes me think you use Rom Manager, and that would explain why it keeps rebooting. There's no need to install CWM separately as it's included in i777 kernels. Rom Manager will ruin your phone, stay away from it (see the sticky).

I don't use Rom Manager.
It was rooted before and I was using a KitKat Rom but I tried to flash the Rom I mentioned and it bricked.
I unbricked it and rooted and installed CWM then it started with the problem.
As I said now I'm using a stock Rom with Android 4.2.1.
You said CWM is included in i777 Kernels so if I root my phone I can simply get in recovery mode and use the stock recovery to flash the Rom?
You mentioned that you rooted the stock firmware and installed a custom recovery, but without knowing your root - recovery process, it's hard to say where things went sideways.
The kernel of the i777 does include the recovery, but the stock kernel cannot be used to flash custom firmware.
>>this guide<< is one of the more reliable ways to go from stock to custom firmware.
summary;
-framaroot to establish root
-mobile odin to install custom kernel
-custom kernel to install custom firmware

I tried to follow the instruction in the link you sent me but I failed doing it.
I searched on google and I saw that Odin has an option OTA / Update zip but mine doesn't have this option.
Is there something I should do before flash a custom rom?

Agreed, the instructions in that guide can be a little confusing.
First, are you sure you are using the AT&T Galaxy S II SGH-I777? Because you said several times in this thread that you are now running 4.2.1, but there is no such version of the os for this phone. The latest official AT&T stock firmware is I777UCMD8 which is 4.1.2.
If you affirm that your phone is SGH-I777 running UCMD8 firmware, and that you have root, then the next step is to use mobile odin to flash AJK v4.9 NoSwap kernel. Download the zip file from the Kernel thread. Open the zip file with an archiving tool such as win-zip, 7zip, etc. and extract the boot.img. Mobile odin will not recognize the zip file, but it will recognize the boot.img as a kernel, and will flash that. So transfer the boot image to the phone sd card and flash with mobile odin.
Next, you will find that the phone buttons don't work. Transfer the AJK v4.9 zip file to the sd card, enter into Clockwork Mod recovery and flash the AJK v4.9 zip file. This will fix the buttons. Now you have a working stock UCMD8 with custom AJK kernel. Now you are ready to flash what ever firmware you want. Hope this helps, and feel free to ask questions.

I did exactly what you said and it worked but when I tried to flash a custom Rom it failed and bricked my phone again.
And now I'm back to the first topic, it always reboots in the recovery mode.
I'll try to fix it again.
I didn't see the error it showed me when failed in flash the custom rom. I know I should have seen it.
Here is a video of my phone rebooting in the recovery mode.

What firmware did you try to flash? If you tried again to flash the "AoCP KitKat from GalaxyS2Root dot com" that you mentioned in your first post, that in itself could be the problem. In the past, many products from the GalaxyS2Root website have caused numerous and various types of problems, including similar to your issue. For most of the past two and a half years, we have been advising people to avoid the Galaxy S2 Root website and products. It is best to flash firmware downloaded from XDA-Developers.
If you are trying to install a version of kitkat on your phone, then you also probably need advice from someone more familiar with kitkat, like cyril279 or SteveMurphy. Maybe one of them will jump in and help.

Just breezed through this and didn't see this mentioned but in the aocp kitkat forum here it states in the op you must be on cwm 6.0.4.4 or higher to flash their ROM. This is true for all kitkat ROMs I've tried so far. This may have been the source of your problem although usually most report getting a status7 error at this point but I'm not familiar with that cwm version you mentioned.
Also twrp works really well and it's touch based.

If you go back to AT&T stock 4.1.2 I777UCMD8 to start over, here are a couple of ways to get the kernel you need. Please bear in mind that the only kernel that will boot UCMD8 into system is the AJK v4.9 kernel that you used before. When you install another kernel such as RenderBroken's CWM or TWRP kenrel, or the one from OmniRom, the system will no longer boot, but you will be able to boot into recovery, so just avoid trying to boot the system, and choose the option to boot directly into recovery. Or... pull the battery and then use the button combo to enter recovery.
1) Extract the boot.img directly from the OmniRom zip file, and flash that using mobile odin. In this case, once you have UCMD8 rooted, you can skip the step of flashing AJK and flash the OmniRom kernel directly. Reboot into the new recovery and flash OmniRom.
2) Flash the AJK kernel as in my previous instructions. Then enter recovery and flash RenderBroken's kernel. Boot directly into recovery and flash OmniRom.

Hey guys,
I am trying to flash CM 11 M8 on my i9300 but I get stuck on the bootloader screen.
This is how it looks:
http : //i . imgur . com/qJAqYf2 . jpg
The only ROM that I could flash on this device is [Resurrection Edition] CheckROM EvoHD™ V4 [ODIN ROM] http : //tinyurl . com/mothcldto
It will boot but it's a 4.0.4 ROM and somehow can't be updated.
I'd prefer to install CM or at least the latest stock firmware.
Not even the stock ROM (I9300XXUGND2; Downloaded from samsung-updates.com) would boot.
Can anyone help me?
Recovery: CWM 6.0.4.3
Sorry for the messed up links. This is my first post, so I am not allowed to post links.
Ok so I have successfully flashed Stock ICS ROM over Odin and CM 9 over PhilZ Recovery.
For some reason I am not able to install JellyBean/KitKat ROMs.
I hope this Information helps.

I am using PhilZ Touch 6.48.4 and wiped everything. The latest CM Milestone doesn't boot. I think this might be a bootloader related problem, but I'm not sure.
I also tried installing Stock ICS Rom, but when I try to do an OTA update the resgistration of the device fails.
EDIT: If I try to read my IMEI it says "null / null". I guess that isn't good.

I have the Samsung GT-I9100.
I have the same problem.
I have installed a TWRP over the the CM13 Recovery, but the TWRP does not find any partition, or file on my System. Even no OS.
So wanted to get back to my old PhilTouch Recovery, but the TWRP always overwrites the Philz Recovey.
I can use the old Philz Recovery only one time after flashing it new with Odin. After Boot the useless TWRP is back.
How can i delete the TWRP Recovery so that my old Philz Recovery will keep installed?
Cheers,
Foh
