I recently acquired a Samsung Galaxy S2 (AT&T - SGH-i777, upgraded to ICS via Kies), my first Android.
After a bit of root researching, I installed Odin (1.85) and then the Siyah kernel
I proceeded to follow the steps listed on a walk through website and everything went smoothly, however when the phone rebooted, the Samsung screen loaded first, followed by the Siyah ICS logo screen, and then blackness.
I can boot into the recovery and want to just erase everything and start over. Yet, because of my noobness, I'd rather ask experts before I go off and really fudge this phone up. WHAT SHOULD I DO NOW?!

Your problem is not clear. What are you facing after rebooting.
Also, what rom specifically did you install? It could be something as simple as an incompatible kernel, in which case it's an easy fix. But we do need a bit more information, please.

It sounds like he didn't install a rom, just a kernel. Yes, I think it is an incompatible kernel.
@dimintia,
My guess is that you tried to install a Jelly Bean version of the siyah kernel, and maybe one that is not built for the SGH-I777. To recover, you can flash an ICS kernel built for the SGH-I777. Or the easiest way to recover would be to use Odin to flash stock Jelly Bean, UCMD8, which you can download from the Download Repository at the bottom of the page. You can then use the Framaroot application with the Aragorn exploit to root.

Hello fellas! This will be on my first post on the XDA Forums. I decided to ask a question in reference to a Kernal Update. I recently got the S3 and decided to follow through with a flashing of a custom ROM followed by a Kernal that gave me an OverClock feature.
ROM: KyanROM
Located: http://forum.xda-developers.com/showthread.php?t=1751595
Kernal: [Sammy] KT747 by ktoonsez
Located: http://forum.xda-developers.com/showthread.php?t=1756776
I really like the ROM and I might be sticking with it until Jellybean. But more over, like I mentioned before, I felt like trying out an OC feature and KT747 Kernal gave me that. My problem is that when I plug the S3 into the PC, it'll sometimes fail recognize that it is indeed plugged in and if it does recognize, my PC won't install the drivers properly until I reboot my phone then re-connect.
So, to fix, I reflashed back to stock kernal and the USB recognition/Driver installation seemed to revert back to it's consistency in function.
Since I can't post in the dev. side of the forum yet, I decided to ask here; Is the issue with the custom Kernal, or could the problem derive from my PC USB ports?
I'm guessing it might be a Kernal bug. Correct me if I'm wrong. I know very little when it comes to Android Developing
Hi, I looked around but can't find a thread similar enough to mine to be helpful.
I have a Galaxy S2 i9100T with Vodafone Australia running 4.0.3 ICS
Earlier, I did a lot of research and absorbed a lot of knowledge, and attempted my first root.
Off to a bad start, as it is not working, and my phone will not boot.
My aim was to root, and root only. Not flash any custom firmware etc.
My kernal version was i9100TDULPB, so I downloaded a modded kernal version, which was CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5
from Chainfire's thread > http://forum.xda-developers.com/showthread.php?t=1103399
and Flashed it on the phone using Odin, the process went well and Odin gave me a 'success'.
However, the phone started up and showed the typical Samsung Galaxy SII boot page, with the yellow triangle down bottom, but then just turned off. I tried booting again, same thing. Vice verca, I could not get the phone to boot past that page.
I can get into Download mode and CWM recovery, I tried booting from CWM recovery to no luck.
So I downloaded another similar kernal from Chainfire, this time it was called > CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER
Which still gave me the same problem. And that is the kernal which is currently on the phone.
And that brings you up to scratch, I'm unsure of what to do now and don't want to risk screwing up my phone any further.
Please explain (Noob friendly ) On what I can do to fix this, I am still interested in having the phone rooted, is there a different kernal you can reccomend I flash? Or a quick fix from CWM recovery? I am new to this, and any advice is helpful.
Thankyou in advance
I think Cf-root is intended only for i9100, not i9100T.
Anyway, try this.

If you want just root then flash back your stock ROM and use method 1 from guide in my signature.
Hi guys.
First up hello. Im a refuge from the Ace section, have a Galaxy SII due for delivery over the next couple of days so Im moving over. On the Ace I flitted between CM7, CM10 unofficial, Lewa and a few others.
Im generally used to rooting via stock recovery and then using CWM to do everthing else, not familiar at all with ODIN as I have never needed to use it. Standard UK SII, unlocked running Gingerbread.
Have read around this section and will continue to do so for a few days, but a few starting pointers would be nice.
Rooting/CWM/Kernels
Whats the easiest way for rooting the SII, preferably from stock recovery
Whats the easiest way for installing CWM?
What the best basic Kernel out there, or Kernel that will do an AIO Root/CWM/Kernel job?
Im reading a lot about this hardbrick lark with ICS, is this purely an issue with stock ICS roms, and its fine to go down the CM10 route?
I can use the search feature, but as Im sure you know thats not always the most productive route.. Although I shall use it in the meantime.
Cheers.
You can learn a lot just by reading peoples problems, and the answers given.
For rooting, you would normally just flash like a siyahv4+ kernel with Odin.
That gives you root, cwm and safe from brickbug.
Theres several other ways also like exynos or doing stuff via recovery.

How have i avoided ODIN so long.. hmm, Siyah 4.
Do you know how cumbersome the search feature is here, finally found the download for v4.1.15 (and then realised it was in your signature), now im trying to find the instruction to install via ODIN,. If you happen to know offhand, the exact thread that would be appreciated.
Regarding roms, Im assuming CM10 is the standard, not familiar with any of the devs over on this side of the fence.
Ok, from what I can gather
Download Keis and make sure all drivers for the SII installed
Download Siyah-s2-v4.1.5
Disconnect your phone from your computer
Start ODIN
Click the PDA button, and select Siyah-s2-v4.1.5
Put phone in download mode
Connect the phone to computer
Make sure repartition is not checked
Click the start button
Wait for the phone to reboot
correct???
(sorry, i suffer anxiety, one of the side effects is double checking anything before doing it)
If your on ICS, you can download that siyah kernel, but make sure you get the .zip type.
Get the 1st and 3rd file in the ics rooting guide in my sig.
Stick them all on sd card.
Boot into recovery.
Flash the 1st file-which is temp cwm
Flash the 3rd file-which is su/busybox
Then flash the siyah file-which gives you permanent cwm and safe kernel.
Then reboot phone.
Then you are rooted, with cwm and safe kernel.
The easier way is obviously using odin.
Ps.hope you aint got the g model.

No, its not the G..
It is on gingerbread currently though, not ICS.
GB ffs......lol.
Right you can update to ICS (pain)
or
Set up Odin and flash siyah s2 v2.6.14.tar file
or
Try exynos abuse (may not work on GB).

I shall go S2 v2 route then. assumedly i can then just flash cm10 iwthout any problems.
Yes GB model, but no, not GT-I9100G
Youll need to check what the install instructions are for the rom
Eg if you need to be on GB or ICS.
Ive never used it, Ive just read you need cwm though.
If possible I would first update to ICS via Kies or OTA then afterwards flash Siyah v4 via ODIN. Once you have done this you are ready to reboot into cwm and flash away. Remember to wipe data/factory reset in CWM though after flashing Siyah kernel and before flashing new rom.

Ah, ive been reading on problems with ics and hardbrick, i guess that is prevented by flashing siyah post update.
Thanks guys, sorry for the noob questions, im not a noob, but rooting always makes me nervous (a hangover from the days when flashing the bios on the pc was a dangerous hit and miss affair), i just like to double check.
Once im rooted and got CWM im back in familiar territory.
Any other general tips on making the leap from Ace to SII appreciated.
Dont you just love it, when the phone arrives and its pre rooted with siyah and cwm
I have a GS 2 I777 on AT&T that ran 4.0.4 with the latest update from AT&T. I used Odin to install Siyah version 3.4.2 and since i have, the phone is in an infinite loop when booting. I get the first screen with the yellow warning icon and the device name, then it goes to the siyah kernel logo, and then back to the device name screen. This repeats over and over.
I've tried putting different versions of Siyah back on the device: 3.2.6 and 5.0.1, but none work and leaving the battery out for 15 minutes
What can I do to fix this?

1)u are in the first place on a wrong thread (meant for I9100).
2)And foolish enough to flash a kernel meant for I9100 on ur I777 phone (which is quite Different hardware wise compared to I9100).
3)U should feel lucky that ur phone is still ON.
4) Visit www.sammobile.com and download a stock firmware meant for ur I777 AT & T version.
5)flash the same from ODIN to get rid of the mess.
6)Finally put some sanity into ur brains and Do some reading before doing anything silly
Good Luck!

You may be able to fix it by flashing a version of siyah or another similar kernel which is compiled specifically for the SGH-I777. If that doesn't work, then as someone stated, you should flash back to stock, or stock plus root if you plan to modify the firmware. See the links in my signature for more information, and after you have read, feel free to ask any questions here.

Hey.
I've been working recently with my brother's AT&T i777 Samsung Galaxy S2. I couldn't root it at first, then i found the note that i777 does not have the bootloader lock, and then i proceeded with installation of CM stable version, step by stop, according to this page:
Install_CM_for_i777 (cannot post links)
So...i downloaded file, renamed it and placed it in my Galaxy S2 internal memory (the same folder where i put files to my Galaxy Nexus).
Phone does not have stock recovery, so i thought about flashing it via Odin after changing file format in Total Commander.
Anyway, i took out battery, placed it in again and...BANG! Phone only boots while on charger or USB cable. I am able to get it into Download mode. That's why i tried to repair it using almost all firmwares (via Odin 1.85), i used Siyah kernel to get it right, and i even flashed the proper bootloader to make it move. On the way, i also flashed some i777 firmwares that were already rooted. No results.
IT ONLY SHOWS THE EMPTY BATTERY SCREEN, FLASHES, AND BACK AGAIN. LOOP.
I would reallly, Reallllly appriciate help.
Thanks!
You've mentioned a lot in your post, some of which isn't very clear to me, so I'm going to ask a few questions in an effort to fully understand where you are. (I'm less worried about how you got there).
The immediate goal will be to get your pone booting into the stock samsung distribution.
We'll cover rooting and custom firmware later.
You are able to get into boot mode (that's a good sign), but are you flashing the stock UCMD8 firmware via desktop Odin?
If no, then flash the stock UCMD8 firmware (see sig)
If yes, when the flash is complete, does the screen show the result: pass?

Thank you for your answer and concern Cyril. But i don't know how (i'm still wondering why) i managed to get it right. In rage, i pushed the battery from the model i9100 (GSM Galaxy S2) and....it BOOTED! The rom and kernel was not right so i flashed already rooted version of firmware 2.3.6 and from that step, when i noticed i had superuser, i installed CM 10.2 stable ROM. During the process of installation of CM 10.2 i had to switch batteries (at most 3 times change battery in order to push phone to recovery and escape bootloop during installation of gapps). Now the phone works well with both batteries and is safe and sound. BUT STILL!!! I wonder why it reacted on the battery from i9100 model? Why this was the factor the phone needed to procede with further modifications? Any ideas? Feed my curiousity, lol.

I've raged on this device a time or three myself, I promise.
The most abnormal part of each of your posts is the battery involvement. You shouldn't have to touch the battery at all for recovery mode, download mode, or flashing, so I would guess that you're up against dirty or failing charge port, a near-dead or failing OEM battery, or similar issue which made your flashing journey more troublesome than it should have been.
There are several posts [like this one] about troubles using i9100 batteries. They fit and function, but exhibit undesirable charging issues, which consequently tend to get blamed on some other aspect of the device.
The symptoms of a dirty or failing charge port also commonly mis-direct users to blame firmware, batteries, and everything-else.
