Extreme Noob question.. if offended please look away now.............
I am currently running stock ics 4.0.3 firmware rooted with cf-kernal on my galaxy sII (i9100),
I want to go back to cm9 nightlys, i had it on previously to this rom im running now,
With all the brickbug posts floating about im paranoid at whether i could safely return to cm9 nightly or any cm9 builds.i have the bugged emmc chip as gotbrickbug v1.1 tells me but im guessing it should be fine to flash back? though wanted feedback as to whether that would be ok,
ive also had various other roms on this phone too, im sure i also had siyah kernal rc3 i think?? not ure on build but all worked fine.
would (in your opinion) flashing back to cm9 brick my phone?
Thanks in advance and please bare in mind i have read around the forum but all the info is confusing when you read multiple threads on the subject.
Only way to get brick bug active on 4.03 if you are on that old siyah with bricking bug.
So if you are stock or cfroot for 4.03 you can use cwm data wipe, restore backup...etc. but if your backup is on 4.04 brick bug kernel your in trouble.
Hope this helps.

still confused
I'm sorry to bump this thread, i tried searching but did not find a final answer.
I'm going to root my phone, and possible install CM9. But the emmc bug confuses me, i have checked with the app and it tells me i have the faulty chip. Is CWM dangerous to use? I read somewhere that you should not use CWM if you had the bug, but others again seems to use it without problems. I also read somewhere that a normal factory reset (without any root or flash) also could brick the phone, is that true? I would really appreciate some good answers on whats safe, and whats not. I will off course press the thanks button a lot!
The phone is stock, i have never rooted or flashed anything.

The ones causing the bricks mate is the stock kernel from sammy's 4.0.4 rom with CWM. Wiping using stock recovery is okay (i tried it). If you use other kernel like siyah you will be safe. In short, Stock kernel from samsung's 4.0.4 update + CWM Recovery + Wipe = Hard brick. As long as you avoid that, you will be safe
Bdw, it is good that you bumped this thread rather than making a new one

You could try that. Bdw, Stock kernel (sammy 4.0.3) + CWM (just like CF-Root) is safe. If you ever wanna try going to another rom and you are on a stock 4.0.4 rom, flash siyah first before doing a wipe
Never wipe using a stock 4.0.4 kernel + CWM recover

Wouldn't using ext instead of internal slow things down? I have a sandisk ultra class 10

Hello everybody,
I have got a Samsung Galaxy SII with stock firmware ICS 4.0.3 which is brikkable for the emmc.
I would like to flash the Cyanogenmod 9; could it give me problems?
Before doing this, I would like to make a nandroid backup by the temporary ClockWorkMod Recovery.
If I would flash the Cyanogenmod 9, and then I would like to restore the old nandroid backup (always by using the temporary ClockWorkMod Recover) ,could it give me problems?
Thanks everybody.

Since you're on 4.0.3., you cant be affected by that particular brick. Only on 4.0.4. with stock kernel and those based on it.
If you backup or wipe in Cwm, there wont be any problems. After that I recommend Siyah kernel if you're gonna flash roms.

Maybe you mean that soon after the flash of the cyanogen9 I should flash the Siyah's kernel?
Hasn't the cyanogen9 an own kernel, or there is still the stock one after the flash?
I would like to try not to increase the internal counter for the warranty..

Cm9 comes with its own kernel which has Cwm. From there you can flash anything you want.
The counter will stay the same unless you flash with Odin in D/L mode.

There have been a few issues with Siyah 4.0, hence a quick beta available to 4.1. I'd suggest you use 3.4.1. Seems to work perfectly for me. You could flash 4.1 once it is out of beta.

Hello everybodies,
I want to give my Samsung Galaxy S2 to my mum after buying myself a nice and warm S3! ^_^
Here's what I'm planning to do:
1/ Wipe with CWM: /cache, /data, /system, dalvik, battery stats, sdcard and external-sdcard, so really everything!
2/ Reboot into Download mode afterwards and flash a stock ROM
My question is: can I do that? Or if I wipe all this stuff I risk not being able to boot in Download mode?
I'm currently using OlloS2 LPX based ROM.

it shouldn't give u any trouble
Download Mode is part of bootloader, so don't worry and wipe freely :good:
Thank you guys!
I know I could find the answer by myself, but I heard that the ROMs LQ5 and LPM have a chance to brick the phone. Therefore, which is the latest safe stock ROM?
U could tru any aokp based rom...they are all safe...
If not search safe ics kernel in search tool and u ll find.some post about wich kernel is safe and.wich not
Sent from my GT-I9100 using xda premium
Thanks for all. I just flashed LPX and everything ran smoothly.
I did some research for a friend, that needed an ICS sammy rom and just for sum up, any ICS sammy version released or built befor july are safe. Since 9 of july samsung included the erease_emmc_cap lineain their Kernels. so...
the problem is triggered when u want to make a wipe/factory reset. if not u can use them without problems
Yeah I also read that ROMs LQ5 and above have a high risk to brick the phone if any wipe is used with CWM using the CF-Root kernels of these ROMs. Is this what you're talking about?
I've actually formatted the internal memory many times when changing ROMs. The bootloader and kernel is on a hidden partition.

First up, sorry for the new thread....
Now....i've just (this morning) upgraded to the S2 (international?)
I live in the UK and my phone is locked to 3 mobile UK.
I'm not totally new to the Android scene....my last phone was a Galaxy W that i rooted, flashed CWM to and flashed unofficial CM10 to.......
Believe me when i say i have put in the screen time on this....i've read xda, android forums, google searched, visited the cyanogen website and even tried github......
The trouble is that every method i've seen says something different....or it's for a different version of the OS....or it's for a different varient of the phone....etc, etc......
All i want to do is root, install CWM and flash JB to my phone with little or no chance of bricking it......

IMHO, the most important thing to do before anything else is to confirm whether your phone has an "insane" EMMC chip affected by a superbrick bug. You have an ICS 4.0.4 installed, which might be a recipe for big trouble if you ever try wiping your data from recovery. Read this for more details: http://forum.xda-developers.com/showthread.php?t=1756242. There is an app here on XDA to verify your chip: http://forum.xda-developers.com/showthread.php?p=27014974.
The rest (rooting, CWM) has been covered extensively. If you want a stock or stock-based ROM, taking a quick glance over General or Development forums will give you sooo much info...
Try to stick to xda forums only.

If you're honestly that terrified, leave it. There's always going to be risk if you flash. How much risk is determined by how poorly you follow instructions/learn (as opposed to having someone give you a bunch of steps to follow you don't understand). If you can follow instructions/learn, that risk is small. The risk increases exponentially with how badly you do those two things.

Read carefully the first thread I referenced - it tells you how to avoid a brick, and it's not that complicated. As already said, you need to understand the steps, rather than just follow them. I have a bad chip, and I am still OK after about 10 or so full ROM flashes (both through Odin and recovery), and probably twice as many kernels... There is always a chance of something going sideways, so you have to decide for yourself. Some phones are easier ro screw up than others. I also have an LG P990 - that phone is literally unbrickable, short of physical damage. Unfortunately, can't say the same about SGS2, but I am still flashing it...
Good luck!
Thats the thing...i CAN follow instructions and read threads etc....(i created a help thread over on the galaxy W forum which was sticky'd that was based on what i'd read and understood)
It's just that i select a thread that might be of use, read it, and discover it applies to a different varient of the phone....or a different OS version...........

-take necessary backup (sms/contacts/apps etc)
-download stock JB 4.1.2 from sammobile.com
-flash it via odin
-if you are stuck in samsung logo, reboot in recovery mode and factory reset & reboot it would be fine
-to root, download Philz latest CWM and flash it.
-you can also try NeatROM lite (which has samsung boaltware removed)

I've been looking at the Dorimanx kernel....if i read it right it includes root and cwm.....is this a good choice? Also am i right in thinking that i can go on to flash ANY cusROM once that kernel is installed?

Yes, it includes root (using Chainfire's SuperSU) and touch CWM. Dori seems to work very well for me. Stable, with nice customizations. Many people would consider it the best kernel, but we know there is no such thing...
Nobody can guarantee that ANY ROM will work with a particular kernel. It's always best to read both ROM and kernel threads about compatibility. Some ROM/kernel combos are known for problems. But Dori is supposed to be compatible with most of the ROMs.
One thing to keep in mind is that CWM will not do a complete Nandroid backup for you - it doesn't include Preload partition. Workarounds are available, like hawkerpaul's scripts, or Onandroid.
Thanks again kt-froggy for your reply and info....
So the steps i need to undertake are.....
1) flash dorimanx kernel via odin.
2) create a nandroid backup (without using cwm)
3)Wipe cache, dalvic and data.
4) flash this ROM....
http://forum.xda-developers.com/showthread.php?t=1794758
And it's associated gapps via the newly installed cwm.
5) wipe cache and dalvic again and reboot.....
Edit....just read further down the install instructions for the Rom and it mentions cwm flashable modem....do i need to worry about that?....

I am not an expert by any means, so don't take my words as the ultimate truth... Others may have better advice. Besides, I know almost nothing about CM, as my preference has always been towards stock-based ROMs... The best option would be to follow instructions in CM thread you mentioned -- it tells you exact steps for installing it. Flash Dori kernel (or any other safe kernel, for that matter) first using Odin, to make further steps safe for you (because of a brick risk with your current 4.0.4 stock kernel). It is supposed to be compatible with CM10 (Dori was saying that CM10.1 is broken). The latest version (7.46) has some mixed reviews, so you may want to use 7.45 - it is available in both TAR and ZIP versions for flashing via Odin or recovery. You can make a nandroid backup using CWM, just run hawkerpaul's script to also backup Preload partition.

Modem (or baseband) is something you can flash separately from a kernel or ROM. Different basebands work better than others, depending on your area and your carrier. I'd say you don't need to worry about it, but you can always try flashing a different baseband if you have some problems (cell and WiFi signal strength, overheating, etc.)

Technically, you didn't need to root your current ROM, since it has no relevance to your ability to flash CM10... For TAR version of Dori kernel, look here -- Kernel-V7.45-[01-10]-[29-01]-TAR-FOR-ODIN.tar. This download link is posted in the kernel's thread.

Not sure if I understood the question exactly... CM10 that you referenced includes its own kernel, so your stock kernel is irrelevant and doesn't have to support CM10 -- it will be replaced the moment you flash it. The only thing you really need to flash a custom ROM is a custom recovery (CWM or TWRP). BUT, as you already know, you have a 4.0.4 stock kernel that is affected by a superbrick bug, and you are not sure about your EMMC chip. So, flash a safe kernel first (Dori is a good option, but it can be a different one). It will include the CWM recovery (permanent -- not temporary, like you used for rooting). After that, you can safely flash your CM ROM from CWM, followed by gapps.
Once you are on CM, your kernel (the one that you flashed before) will be gone and replaced by the CM kernel. You can keep it, or, if you want, you can then re-flash another kernel of your choice (Dori or other).
Hi Everyone!
This is my first thread on XDA.Hope I'll get quick and helpful replies
I just bought a samsung galaxy s2 at&t variant.
1 - The phone is rooted and superuser is intalled but when I go into recovery its something like android 3e recovery which is stock recovery I guess,so my question is will I be able to flash using this stock recovery if not should I re-root my s2 to get clockworkmodrecovery or is there any other method to get cwmr?If I have to re-root my s2 then whats the easiest way to do it?
2 - How to flash custom rom without risk of getting bricked?
3 - How to make backup of stock ROM and other things?
4 - Another question is my phone is unlocked now and will I loose it after flashing?Suppose my phone is locked again so will I get my phone unlocked again through galaxsim or similar softwares without any hazard and use any sim I want?I read somewhere that its important to use the same software for unlocking again that u used before,is this true?
5 - My phone is running on 2.3.4 and I want to upgrade to either ICS or JB.Are there stable JB and ICS roms available for s2 i777?

Hi Everyone!
This is my first thread on XDA.Hope I'll get quick and helpful replies
I just bought a samsung galaxy s2 at&t variant,the phone is rooted and superuser is intalled but its not rooted with clockworkmod bcz when I try to go into recovery it takes me to something like android 3e recovery,so my question is will I be able to flash s2 using this android 3e recovery if not should I root my s2 again and if yes then how,whats the easiest way to root it again with cwm?I've experience rooting with odin...
Once the rooting is done then how to flash custom rom without risk of getting bricked?
Another question is my phone is unlocked now and will I loose it after flashing?Suppose my phone is locked again so will I be able to unlock it through galaxsim or similar softwares without any hazard and use any sim I want?I read somewhere that its important to use the same software for unlocking again that u used before,is this true?
My phone is running on 2.3.4 and I want to upgrade to either ICS or JB.Are there stable JB and ICS roms available for s2 i777?
Is there any official update of android for I777?
Some more info:
Baseband Version:I777UCKH7

I'll give you a quick head-up then you go off and do your own.
In the bold, since it's rooted, get the Odin Mobile, flash the custom kernel which should already included the CwMR. From there, boot into CwMR and flash any custom ROM you want.
The open sentence, you said the phone is rooted, then you asked how to root, I think you need to understand more. Anyway, read those Stickies threads more and more. For the starter, search for "creepyncrawly" and read ALL threads in his signature.

Do cwm and rooting have any relation?
The phone is rooted but when I go into recovery its other than cwm and through which I can't install custom rom so I asked if I have to "re-root" to get cwm or not...
Things are little clear to me after reading stickies.
Ignore the first two questions and answer the others plz.

Root and CWM have no relation. Having root will allow you to obtain CWM by flashing a kernel that includes CWM. All of the kernels for our phone on this site include CWM. So as votinh mentioned, install mobile odin (which you can find on this site), and then flash one of the kernels from this forum, which will give you CWM.

If you get and get to know with 1 and 2 then question 3 will be easily answered.
Get into the recovery, play and understand all options, it's not many though.
About 4, I said 80% you will not lose the unlock if you understand the factors. It means 20% is your fault if you do not follow the instruction so go off and hunting that 20%. Be sure of what you do.
About 5, do you know what version of OS currently on your phone? Get it right first before doing anything else.

I777UCKH7 Gingerbread 2.3.4 (original release firmware)
I777UCKK6 Gingerbread 2.3.6 (various issues)
I777UCLE5 ICS 4.0.3 (the kernel may have contained eMMC cap erase bug)
I777UCLC3 ICS 4.0.4 (serious sleep of death issue)
I777UCLL6 ICS 4.0.4 (fixes sleep of death issue)
See the links in my signature for 1,3 and 5 firmware downloads. Also see my signature to discover my favorite Jelly Bean.
Ok so before flashing custom kernel and rom after that,should I backup stock ones ?
"Nandroid" will this app help me in making backup of stock rom and kernel and also to recover whenever I want?I am just asking bcz I had bad experience with it when I made backup of stock rom on my galaxy mini.I was confused between root and cwm bcz when I rooted my mini cwm was included with it without flashing custom kernel.
Which kernel to flash,any specific?

Sure.
Use the UCLL6 plus root package from the link. The one-click downloader is easiest. Then, if you want, install Mobile Odin lite or Mobile Odin pro and use it to flash a custom kernel such as AJK or Siyah.
And... I would suggest you read through the first link in my signature to learn the basics.

Dude is there any risk of getting my phone locked after updating to this package?
And what would u suggest me to install custom ROM or the official one!

Not really sure, but probably not. AFAIK, most of the lost unlocks happen with Jelly Bean. But if it does happen, you should be able to unlock it again with galaxsim unlock.

Depends on what you want. UCLL6 is Ice Cream Sandwich, 4.0.4. If you prefer Jelly Bean, there are several great firmware distributions, both Samsung based and AOSP based, available in the development section of this forum.

1. Enter recovery and perform a wipe data/factory reset.
2. Open one-click downloader on your pc's desktop.
3. Put your phone into download mode.
4. When the phone is recognized in the one-click downloader, press start.
If you need detailed descriptions of these steps, read the guides linked in my signature.
After the phone restarts with UCLL6 stock plus root, I would suggest you use Mobile Odin to install a custom kernel as I mentioned before. The phone will run better, and you avoid the possibility of the eMMC cap erase bug, if that still exists in the stock UCLL6 kernel (which is unknown).
If you want custom firmware instead of stock, you are now ready to use ClockworkMod Recovery to flash that new firmware.

Not trying to be mean here, but every single question you asked has already been answered and is freely available here on xda to read. Read every sticky note (those are important threads) and search for any issues you have questions about, either using google or xda searche. I realize its easier for you just to ask. But a lot of time and effort was made to make the threads that already exist to help new members and allow our forums to remain unclogged with many threads pertaining to the same questions. I do wish you all the best, and it can be overwhelming. But we've all got to be held to the same standard .

Your friend most likely corrupted his efs while trying. Did he back up the original efs?
He should try this tool to see if that fixes it.

Well I got this device from a great friend of mine @DowntownJeffBrown. Its a T-Mobile Vibrant (US). Now I'm using it in India.
It came to me with a CM10.1 ( thanks to my friend there ). My previous phone was a tiny Galaxy Y. It had just GB and no ICS. We just got CM7 a month back. After using that... the transaction is a bit difficult. (I just got the phone yesterday though ).
My questions are just basic noob ones but reading through guides here..most of them are solved. I still have some thus the thread. Well let me start.
As I have CM10.1 now... If I have to change the ROM...do I HAVE to flash froyo? And after the Odin... can i directly flash the ROM.zip or do I have to install a kernel or flash a CM7 or a CM9 or a CM10 before proceeding?
Can I get a temporary CWM or is it available only with kernels?
ROM zips come with an included kernel? If then... Can I flash them directly from froyo?
I read in one guide that I'll have to flash the SAME Rom.zip twice (after a reboot ). Is it necessary? And can someone explain why that is important?
Can I flash the modems? I saw that the modems listed are for US ONLY. Well the phone was from the US but right now its half way around the world...will it work?
What is the necessity of a bootloader?
I appreciate every help I get

Hi,
Q: As I have CM10.1 now... If I have to change the ROM...do I HAVE to flash froyo? And after the Odin... can i directly flash the ROM.zip or do I have to install a kernel or flash a CM7 or a CM9 or a CM10 before proceeding?
A: NO. you can flash ROM without flashing froyo (go back to stock before flashing a new ROM). You can directly flash through CWM the ROM.zip
Q:Can I get a temporary CWM or is it available only with kernels?
A:There are two options here. Choose which is best for you, before you start.
ROOT ONLY METHOD:
A – This is an update.zip (633KB) that roots your phone only. You can then install Rom Manager from the Market to flash CWR (Clockwork Recovery) and install custom ROMs.
INSTALL CLOCKWORK RECOVERY AND FLASH A ROM THAT WILL GIVE ROOT ACCESS (MY PREFERRED METHOD):
B – use the other update.zip (1.7MB) and this will flash CWR for you – allowing you to immediately flash a custom ROM.. I do this because it's faster.
source: ★★★ NOOB GUIDE :: Root :: Odin :: Files :: Guides ★★★
Q:ROM zips come with an included kernel? If then... Can I flash them directly from froyo?
A: withing a ROM the kernel is also included. But It can be changed later by flashing a different appropriate kernel. YES, you can directly flash from froyo without any issue.
Q:I read in one guide that I'll have to flash the SAME Rom.zip twice (after a reboot ). Is it necessary? And can someone explain why that is important?
A: Yes it is needed sometimes when you get a boot loop after flashing a new ROM b/c to update the recovery.
Q:Can I flash the modems? I saw that the modems listed are for US ONLY. Well the phone was from the US but right now its half way around the world...will it work?
A:YES. you can flash modems. Only thing matters is choose a modem based on your OS (ICS/JB/CM7 etc)
Q:What is the necessity of a bootloader?
A:Bootloaders were introduced for solve recovery and rainbow issues on Gingerbread ROMs.
When we got Gingerbread ROMs, we also faced the issue of not being able to see the Recovery on the GB Kernels and having to see our screens go funny which were safely called Rainbows! Well, no more !!

I prefer Bootloaders b/c it gives better key combination

Great!
Let me clear myself...
1. I don't need to flash froyo every time I want to flash a new ROM. Even if I'm on any ROM(GB or ICS or JB )
I just boot boot into recovery >wipe data and system and Mount everything back flash my new Rom and done? And oh... Flash the zip again.
( how do I know when I have to flash it twice?? )
And about bootloaders... Do I HAVE to flash them? Can I do stuff without them? ( i never had to deal with it before )
And...
Since the phone is a US phone... Which firmware do I chose? US or Indian (if any is available that is )

Bootloaders are unlocked so that u can flash things like new radio's. So if u are only going to flash roms and kernels u will never have to worry about the bootloader.
I'm pretty sure that radio's are universal as in there is no Indian radio and USA radio. There is just vibrant radio's that work all around the world universally. But I may be wrong this because it's been so long since I used the vibrant.
As far as flashing a new Rom you should just have to reboot into recovery, wipe data and system, then just be able to flash a new Rom. I'm not quit sure why that one Rom u showed me tells u to flash it twice. But again it's been so long since I used the vibrant that I'm not sure. I can tell you this when I flashed cm10.1 on it before I sent it to u I just use these steps
Reboot recovery
Wipe data/system/caches
Flash Rom
Flash gapps
Reboot
But let some of these guys clarify it for u because they are the experts on this phone at this point not me.
Cheers brother

A: Yes. you don't need to flash froyo (which means ODIN back to stock) prior flashing a ROM. You can simply boot into recovery and do a FULL wipe (data/system, cache, dalvik) and if needed format the system under mounts (please refer the installation guide provided with the ROM ). Also re-flashing the ROM depends. It will not happen all time. BUT if it has to be done it is inserted in the OP. Further If the 1st boot after flashing ROM is unsuccessful don't panic and do a battery pull and re-flash the ROM.zip b/c sometimes recovery needs to updated
Q:And about bootloaders... Do I HAVE to flash them? Can I do stuff without them?
A: No. its not essential to flash bootloaders. You can proceed without them.
Q:Since the phone is a US phone... Which firmware do I chose? US or Indian
A: You can use any firmware (I think you are referring to radio/modem) which supports vibrant and the OS you are running. Modems are not based on location BUT the results depends on various locations.

OK... Kinda got it all the way Thanks Haarsh and Jeff
Just one thing for now...
The last part... The firmware is the PDA CSC and modem thing we flash right? At least that walhat was for me before ( galaxy Y ). We had to flash back to the stock firmware every time we needed to flash a different ROM. It used to be region specific and kept updating... But here its just the froyo one right?

Yes. PDA and PIT are used when going back to stock using odin. This link shows [GUIDE] How to Restore or Recover Your Samsung Vibrant using those files.
A Samsung Galaxy S ROM has a few parts :
kernel -> includes the linux kernel, which is the core of the Android OS, drivers to communicate with the hardware. Froyo includes Linux 2.6.32. Gingerbread is 2.6.35.
PDA -> most of the stuff, android and samsung applications, ringtones, etc.
Modem (or phone) -> the radio firmware. Without this you have 0 communication with the cell tower.
CSC -> customisation for a particular provider or country
The PDA can also include the kernel (zImage file)

I meant in my old phone... There were three files ( PDA , CSC and modem ) that we had to put in Odin while flashing but here its just one file ( froyo stock image I guess ) in the PDA slot. And also the pit file ofcourse!

Just to maybe save you some trouble in the future.......
Froyo is 2.2 and stock for the vibrant is Eclair 2.1, you can find froyo odin images but that is not stock.
With the vibrant you can flash roms without needing to go to stock everytime if the os is the same or if you are upgrading, never downgrade through recovery mode.
You only have to flash back to stock (or froyo) if you plan to downgrade, for example you are on jelly bean 4.2 and want to try gingerbread 2.3.
The only time you should have to flash twice is when you are upgrading, for example you are on 2.2 froyo and want to try jelly bean 4.2, recovery is updated with first flash then second flash installs the rom.
Everything else has been answered by haarsh in deatail, refer to his posts.

Yes it will be wiped, that is where your apps are stored. Just back them up first and and restore (app only) after flashing a new rom. Things like pictures and music will not be wiped though.

Take a look at this thread and read it from front to back. It was when we got ICS, but there are many bits of info in there for bootloaders, why we have to flash certain things in certain order, hazards and pitfalls.

Hi, yesterday I bought a Galaxy S2 from AT&T and I'm a newbie at this. I want to know which is the best kernel for this phone without any brick possibilities.
Because I know the Siyah kernel, but I don't like it just because the Ying-yang symbol at booting process (That's really stupid) and I heard that the Jeboo Kernel leaves your phone with the triangle and without the possibility of booting the phone. Stuck at "Samsung Galaxy S2" and the triangle, so first of all... Is this true? (I mean the bug of the Jeboo Kernel)
And second, if it's true... Which kernel can I use?
I forgot to say...
The S2 has 4.1.2 Stock Unrooted.
Thanks in advance.

Stock unrooted. First you'll need to follow one of many threads detailing how to root the phone, and get cwm onto the i777. Then you'll need to read each kernel forum with recent support for the i777 to determine which is best suited for your needs (stability, rom choice, vanity, whatever). A few big names around here are AJK, jeboo (which works fantastically for it's designed application), and STI.
Happy flashing.
Ok. I'll do that.
Thanks.

Then you'll need to read each kernel forum with recent support for the i777 to determine which is best suited for your needs (stability, rom choice, vanity, whatever). A few big names around here are AJK, jeboo (which works fantastically for it's designed application), and STI.
Happy flashing.

One thing more. If I leave the phone with stock unrooted kernel and I do a Factory Reset, will the phone brick?
Because of the eMMC bug with stock unrooted kernel.

I'm pretty sure that stock 4.1.2 left the eMMC bug behind, the details are in creepyncrawly's repository. Creepyncrawly's signature is the best starting point for modding the I777.

Hi, yesterday I bought a Galaxy S2 from AT&T and I'm a newbie at this. I want to know which is the best kernel for this phone without any brick possibilities.
Because I know the Siyah kernel, but I don't like it just because the Ying-yang symbol at booting process (That's really stupid) and I heard that the Jeboo Kernel leaves your phone with the triangle and without the possibility of booting the phone. Stuck at "Samsung Galaxy S2" and the triangle, so first of all... Is this true? (I mean the bug of the Jeboo Kernel)
And second, if it's true... Which kernel can I use?
I forgot to say...
The S2 has 4.1.2 Stock Unrooted.
Thanks in advance.

If I'm bad at English is because I'm from Argentina and I'm learning.

To your initial question, there is nothing wrong with the Jebo kernel. It was, however, built specifically to go with the SHOstock3 rom. There are a variety of things that can cause the problem you stated. Flashing the wrong kernel for instance, as in flashing an ICS or Gingerbread kernel to a Jelly Bean system, will prevent the phone from booting. As far as the warning triangle at boot, that is caused by flashing a custom kernel using Odin or Heimdall. The screen can also be removed by flashing a stock kernel using Odin or Heimdall.
As far as the cap erase eMMC brick bug is concerned, that showed up in the ICS versions, and was possibly present in the 2.3.4 stock kernel. It may have been present also in the 2.3.6 stock kernel but there was never any direct evidence that it was. The 4.1.2 stock kernel is almost certainly safe. If it were my phone, I would not hesitate to perform a wipe data/factory reset with the 4.1.2 stock kernel.

Tour explained me very well, I understood everything! So thanks.
I will choose the kernel later.
