[Q] Safest way to avoid superbrick bug? - Galaxy S II Q&A, Help & Troubleshooting

Galaxy S2 i9100.
Bad chip.
Bad Firmware: Stock 4.0.4 with (Stock) Kernel XWLPT.
Rooted with S2Root+Using SuperSU.
Searched forums, only similar thread is for Galaxy Tab. I'm assuming it's not relevant enough for me to follow it directly.
If possible, explain it like I'm 5:
What is the safest way to install a custom ROM? (Ideally, I want to install CM9 and later CM10 when it is more stable). I've seen people saying to flash Siyah kernel first, then do whatever afterwards. How can I do this? Almost a complete noob here, what buttons do I press in Odin and what procedure do I follow to flash a safe kernel then a custom ROM.
NB: USB is a little buggy, on-device flashing preferred for that reason.

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.

yeah it is. Even wiping data won't cause problems. Siyah isn't affected by the emmc bug.

yea your phone will still look the same. A custom kernel doesn't change your ROM or data.

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

Thanks for all the help so far.
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
I'm korean.. so my english speak is not so good.

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?

[Q] Need help with rooting [official ICS 4.0.3][UCLE5]

Hello guys, So I'm fairly new to rooting (first android/smartphone/ but good experience with PCs) and was wondering if anyone could help me out. I'm using the ICS 4.0.3 build from kies, with the UCLE5, and build number IML74k.CLE5.
*from reading the stickies I've learned to NOT use ROM manager, galaxys2root.com, and to not use the STOCK ICS method as it has a brickbug ( the ones on forum)
Last night I tried rooting my phone by using Doomlord's guide but it didn't work ( I had unknown sources, and USB debugging on*but my phone was on and not on download mode or anything* )
Then I tried SuperOneClick root and it was just stuck on one of the steps, and the only way to stop it was to end task the program and ADP...any tips on what I'm doing wrong? Sorry for being a nub lol
*please move to Q and Q accidently posted in general section
Just use Odin to flash any ics kernel u want.
so I guess Ill try to flash using step 3. on http://forum.xda-developers.com/showthread.php?t=1285894 using ODIN3, then install a kernel ( i want to use 3.3d Siyah ) and then flash a custom ROM (like semi_v17) *the guide from here http://forum.xda-developers.com/showthread.php?t=1650948 correct?
I also want to add that after i Root using 2c.) How to root by flashing Entropy512's Return/Unbrick to Stock, Kernel + Rooted System Package with Modem using Odin3 One-Click Downloader (Windows) that method, I boot into 3E recovery and perform data/factory wipe, wipe cache, dalvik and reset extweaks profiles...then install semi_v17 ROM while in recovery mode and done? Just making sure before I do anything with my phone
I know that relying on the sticky posts leaves some confusion because of Gingerbread and ICS versions. The Entropy512 stock plus root is a Gingerbread firmware with stock kernel and root. If you go that route, you then need to install a Gingerbread custom kernel, and then you can flash Semi from ClockworkMod Recovery if that is what you want.
In my opinion, since you are already on UCLE5 stock, the best route would be to flash the UCLE5 stock plus root package that you can download from the development section, and then install a custom ICS kernel. I know you were trying to avoid the Emmc Superbrick Bug, but since you have stock UCLE5 with the stock kernel on the phone now, you already (supposedly) have the Emmc Superbrick Bug present in the stock kernel. All the instructions needed to install a custom kernel are contained in the OP of the UCLE5 stock plus root thread.
If you have additional questions, just ask.

So I flash the build from this [Heimdall][Odin][Stock][Root]UCLE5 Stock ICS with Root..(no need to flash according to thread)
pick one of the the three kernels (prob going with AJ siyad) and install using Odin lite..then ROM? (like Semi v17?) it gets confusing at some parts cause on the Stock ICS + root section is says to wipe before flashing if coming from another base (im guessing since im on the UCLE5 base i dont need too)

Yeah just use mobild odin to flash a kernel and then boot into recovery then wipe then flash semi. I really wish we could update those stickies. They are pretty confusing
One last question...sorry for being a complete noob lmao after I get the kernel, I boot into CWM recovery wipe...and use mobile odin to flash semi?

Cf root will give u root and CWM recovery, so u're be able to install custom rom
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?

4.Flash SiyahKernal

So CF-Root have CWM(i i guess that is Custom recovery?)

Yes cwm is custom recovery.
First install rom than kernel. Wipe your phone from cwm before you install a new rom.

Do you know WHY you want a custom recovery?
Are yo udoing it because other people told you to or because you know what are the pros and cons of doing so?
If you just want root, you can just install Siyah kernel using Odin. That will give you a custom kernel + root. You can only use MobileOdin (which is great!) if you are already rooted.
There is no need to flash CWM or anything else, unless you know exactly what you'll be gaining or losing from it.
I suggest you take a look at the posts from the past 2 weeks and you'll notice that a lot of people are having problems with CWM. The most common is the lack of USB connectivity to the computer.

When i flashed my SGS1. I used ClockWorkMod. So i was thinking i will be needing that for flashing CM10 and Siyah Kernel.
And no. I don't know the pro's and con's with CWM(?).
Do i need cwm when, flashing a ROM and a Kernal?
You need a custom recovery to flash, yes. Root your device, install a recovery, and flash you Rom. There are guides here where all is already written.
As we can't do things for you, it's good to read a bit...

No, you don't.
Just flash SiyahKernel using Odin3 through a USB connection. That's it.
I've done it on SIII of several friends, and in no moment I used CWM.
CWM is so full of bugs it is more trouble than a solution.

Until you fully understand the pro's and con's of a custom recovery, I advise you to keep the stock one.
Read more of the post in these forums, specially the stickiers, read reports of users with problems, and so on. You'll come to the conclusion that a custom recovery, such as CWM, is uncessary for most users.
For what you want, however (which seems to be flashing a custom kernel + rooting), they aren't necessary.
Like I've written, you can flash Siyah using Odin. This will also root your device automatically. From then on, you can simply use MobileOdin to flash kernels and ROMs, while keeping your phone rooted.

From:
http://en.wikipedia.org/wiki/CyanogenMod
The CyanogenMod source code repository also contains the ClockworkMod Recovery (a "recovery image", maintained by Koushik "Koush" Dutta), which is used to install CyanogenMod and other custom upgrades. A recovery image is a special boot mode, which is used to backup or restore the device's storage and repair or upgrade system software. ClockworkMod Recovery can be automatically installed onto many rooted devices supported by CyanogenMod with Dutta's companion app, "ROM Manager", which is available on the Play Store. CyanogenMod does not need to be installed with a ClockworkMod Recovery, others such as TWRP (TeamWin Recovery Project) work just as well. Some users have experienced hard bricks from "ROM Manager".
Just to clear thing's up here!
This is what í will do?(i have choosen to use CWM)
PS. I Don't want to use ODIN(Desktop)
1. I root my phone with CF-Root and install CWM automatic i guess(?)
2. Than i use CWM Manager to flash CM10(?)
3. Than i use ODIN Mobile to flash SiyahKernal(?)
Or could i flash SiyhaKernal first. And than flash CM10 with CWM Manager for example?
Or could i just flash the kernal via odin without rooting my phone before i flash it?
1. Root your phone
2. Install Cutom ROM (CM10)
3. Use CWM (if installed) to flash SiyahKernal
I used Odin to root my phone and I have a CM10.1 nightly installed right now. I am about to flash the Siyah Kernel but I wonder - since I like being up to date with CM nightlies, will installing a new nightly override the Siyah kernel? Will I have to reinstall it every time?
The way I get it is a kernel sits between firmware and hardware - so by installing new FIRMWARE the kernel is untouched. Is that correct? I am glad for any information on this.
Thank you a lot in advance!

The CM nightly roms as with all other s3 roms have boot.img in the zip (i.e the kernel) so yes, flashing a new rom overwrites the kernel.

Yeah, all good but, have you read this?
Is your device a GT I9100? Are you on 4.0.4? Got the brick bug? You know siyah is a safe kernel?

The thing is where you're flashing from.
And yes, only 4.0.4's kernel's dangerous.

If you want to go from stock ICS to stock JB you have no need to root.
All you do is simply reboot into download mode (Power on using Volume Up + Home + Power) then flash the JB md5 file via ODIN.
Once you have flashed the file you may find system wont boot into rom (this is normal). Just reboot into download mode and flash latest version of Siyah kernel (.tar file) which will be Siyah v6 beta4 (or above). This will give you cwm recovery, better battery life, root access, SU etc.
Go and have a look at some topics/search etc, All the info you need is already on here and if you try and take some shortcuts you may run into problems or even possibly brick your device so take some time and learn.
PS. Yes the eMMc brick bug is part of stock 4.0.4 kernel so just dont go into stock recovery. You can also brick device by your flash process getting interrupted so make sure you have drivers installed correctly (install kies) and taht you're not running any other programs while flashing and also that you have at least 55% battery.
It's a very good thing you are reading before getting the bad boy you intend to flash.
See the thing about this bug is when you make a back up, wipe things up from the recovery, and flash via oding. Once you do the wipes, you are kinda screwed.
Now, you got a couple of choices here:
1) Your device arrives with 4.0.4 ICS, flash siyah kernel (I'll get you off the hook).
2) Arrives with 4.0.3, you are good to go, no danger.
3) You can try mobile odin, it flashes with its own kernel and, apart from being fast, it's easy.
4) If you get a gingerbread version, you good as well.
That being said, I'd advice you to play with it for a couple of days instead of flashing right away.
Check out some videos, read something about ExynosAbuse (It'll get you rooted with one click) and revolv around the q&a section looking for "not to do list".
good luck and remember, keep on reading.

Thanks a lot for all your help
the ressurection remix rom i downloaded came as zip file.I can flash it from cwm itself right?
and regarding the kernel im a bit confused between siyah and dorimanx .I know it depends on phone but what would u suggest?ur personal choice
and i need one more help.I need a vanilla jb rom.Not too much bloatware and with less bugs as possible and tweaked for performance and battery.The problem is net speed is very very low...trust me..i cannot try most of them unless i wait for weeks.So if anyone can suggest i can download that alone and do

Android wont boot up after CWM

Hello. I have galaxy S2, and I wanted to install CWM. I installed it (CWM-KitKatCompatible-i9100) with odin with auto reboot unchecked and after that it doesn't boot up. It can go to odin and CWM modes, but the android doesn't launch. I did a recovery to phone storage, but still I cant launch the phone... Can anyone help me?
Flash a compatible kernel to your installed rom via recovery. Or you can flash an insecure kernel via Odin.
Simple cwm flashing won't boot up your phone.

Would you mind explaining how to flash a compatible kernel to my phone via recovery? Also I didn't install any rom just cwm. And where should I get a proper kernel to my android? Sorry for dumb questions, but I'm not experienced enough as you see...

Well, there are 3 kernels which are quite popular here which have their depth range till kitkat roms.. A simple search on xda for them will lead you to the respective threads.
1. Gustavo's
2. Dorimanx
3. Apolo
If you want a KK rom then download a KK compatible kernel mentioned in the op for those threads, put that on external sdcard and boot to recovery. There you can flash the Kernel file. As you don't have a rom on your phone it would be better if you download a rom and gapps package too and flash them. After flashing a kernel, reboot to recovery and then flash rom and gapps.
If it's difficult for you to put those files on sdcard, you can flash a stock rom via Odin, flash a kernel e.g. philz, apolo,hirox via Odin. Search for these keywords here on xda. Once you have a working kernel and rom, you can download a custom rom and gapps, put it on your phone and follow the procedure which I mentioned first.
If my steps are still confusing to you then you require to search for these terminologies here on xda,read and understand them carefully and then proceed.
You didn't mention what OS/Firmware was on your phone before you started.....this is VERY important to know as it will decide what you can / cannot flash.....
Custom kernels are OS version dependent.....some will only work with ICS, others will only work with JB.....some are exclusively for KK.
You need to check this.....
My wife says I'm a phone geek....She's probably right

well I couldn't check cause it couldn't boot up, unless there's another way... But whatever I managed to write 4.4.2 Kitkat on my S2 and there's alot missing feature's like, I cant organise my program menu, I cant add many widgets that I had used in my previous android, there are no notes, phone file explorer and other what is irritating... Maybe there's some another pack that I missed when installing or what?
