Check definition of kernel here
The brick bug only affects the stock kernel of official ICS 4.0.4 firmwares.
Except you want to do something else, Why do you need any kernel if you only need to install?

Basicly kernel determine how your phone work mean kernel is connection between hardware-software for example with custom kernel u can change CPU/GPU OC/UV and few other things kernel determine how your phone react for touch that for basic

[Q] Just flashed Siyah Kernel on Omega Rom.. Gives black screen

Hey all,
I'll try keep this short and sweet. I just flashed Siyah Kernel 1.5.4 on my GS3 (currently running Omega v26) and it flashed fine, rebooted the phone and logo showed up all good. However, past that stage the screen goes black and I'm not sure if it's actually booted into the phone.
I can press the menu/back buttons and they respond, but nothing shows up on screen. I can also enter recovery/download mode, so I've tried reflashing the original CF-root kernel and still no luck.
Currently going to try a nandroid restore but does anyone have ideas what the case might be and how to fix it?
Cheers,
poopehz
You need siyah 1.6x for roms based on jb leaks.

Thank you Theshawty, this was it. I automatically assumed the kernel I downloaded from Omega Kitchen app would be compatible.. apparently not.
Appreciate the help.

i want to do factory reset so i can customize phone how i want and delete all pics, musics ... i should go to Settings > Back up and reset > Factory data reset, it's easy but i have question: i know for emmc bug, but i'm not 100% shure what he's doing, i know he is on stock 4.0.4 kernels, i have Model: i9100, Android version: 4.0.3, Baseband version: 3.0.15-I9100XWLP7-CL340913 [email protected] #3, Build number: IML74K.XWLP7, is safe to do factory reset ? and do i have emmc bug with that kernel and stock 4.0.3 rom ? Thanks and sorry if my english is wrong

If you're on 4.0.3, you dont have the emmc bug. but you can always download the got brickbug app from the playstore and check, just to make sure.

To be 100% safe, first flash a custom kernel like siyah via Odin. Then you can factory reset your phone without worrying.

From what I'm given to understand the app just checks the firmware and compares it to a known list of 'bad' chips.
If you're on gingerbread you surely have nothing to worry about.
However if you plan on rooting your phone don't directly flash siyah. There are guides in the general section. Look through those.

My phone is already rooted and the thread in post 5 is talking about 4.0.4 firmwares. isnt there anyway to solve this emmc bug problem?
brickbug ONLY applies when wiping data on STOCK 4.0.4 kernel... If you are on gingerbread or ics 4.0.3, you wont be affected.

I want to flash siyah kernel, what is a better way, to flash it via odin or to install it via recovery?
Sent from my GT-I9100 using xda premium
Flashing via recovery won't increase custom binary counter.
I dont care for that because my flash counter is already increased so i have yellow triangle but im ok with that, if i flash siyah v4.1.5 can i back to samsung stock kernel and how?

Sure, by flashing stock firmware via Odin.

Yes, you can downgrade to a Gingerbread stock rom from the ICS rom you're currently running.
You can download GB stock roms from Samfirmware.com or AndroidFirmwares.Net.

Sent from my GT-P6200 using xda premium
Glad you got it sorted
I always liked using Siyah on GB roms. But one thing you need to watch out for - make sure you flash a Gingerbread kernel now you're running GB stock. If you flash an ICS or JB kernel, your phone won't boot (doubt you'd brick it outright, but stranger things have happened here).
As long as you do that, you'll be fine Have a look in the development sections of the board & you should be able to find threads with GB kernels that work with stock.

Hi, if you are doing OTA it will be 4.2.2 or 4.2.3 at best, you will loose root, but not files or data.
Some apps may stop working or work differently, nothing to worry about.
Thanks and hows that? Major improvements? Something always weird with this one was the greenish tint when shooting with the flash... Is that fixed?
And there is a new chainfire's root out there i guess....

Just want to say this isn't correct. Don't know if it's mistyped or something else, but it should be 4.1.2 'at best'.
Last official (thus OTA available) update for S2 will be 4.1.2. Sad as it is, for today's standards it is still acceptable.
what do you guys think about the 4.3 like sentinel rom?

4.1.2 is the latest (and last) official Samsung update. There are 4.2 and 4.3 roms available, but those are custom ones.

Yes i was wrong, long time didn't have to use stock.
As for ROM selection, try PAC rom, (latest nightly 4.3.1) I am really happy with this rom as my dd.
thanks guys, I am about to upgrade, just a question, can I use the OTA update even if my phone is already rooted and I have Siyah kernel on? is it going to break or get stuck?

The OTA will probably fail.....the OTA package looks for a stock setup, and if you've modified that setup in any way (custom kernel) the OTA won't install.....even if it *didn't* fail, the kernel would be overwritten and you'd lose root.
If it were me, I'd make use of chainfires mobile odin, download a jb firmware from sammobile and update that way......

Did you enable the 'ever root' option in mobile Odin?
If not, you'll have to root the phone afterwards (if you want to)
A good place to start is the PhilZ kernel (rooted stock kernel + touch cwm)

thanks again for the help
Gab
Yeah....I guess that's 'project butter' or whatever it's called....it's supposed to give an overall smoother performance........
If you are going to stay with stock, my advice would be to 'de bloat' it.....I used Titanium Backup to freeze the bloat first, then delete it after I'd found out that it wasn't needed/critical for the phone to run.......
