So I decided to root my Samsung S2 i7777. Had years of experience flashing HTC hero and Hp touchpad. Thought this might be straightforward as well. Proceeded to get ODIN and ATTGalaxyS2RootStockZedomaxKernel.tar. Flashed it and got pass. Phone proceeded to reboot and was stuck on the Exclamation mark. Tried restarting but no luck same thing. Initially had CWM coming in when I tried the Volume and Power button trick but could not do anything beyond that.
Then I decided that maybe my flash was not proper with that file so I took the siyah kernel and flashed that. This was a pass as well and then back to...the exclamation mark. Now, I cannot get CWM and retarating the phone with the USB connected lets me get into the Downloading window, but I cannot do anything beyond it.
What can I do? Do I need to flash a ROM- is that why I am stuck? How should I flash the ROM from ODIN- if I do get CWM back, can I put the ROM on the SD card and flash it using CWM?
Please help- I am getting stressed out and if I do recover from this, I am going to take a break from rooting :laugh:

I think you should head over to the stickies and look for creepyncrawly's thread. It sounds like you should also be able to flash firmware through download mode if kernels are working. Also, stay away from galaxys2root and zedomax in the future

You shouldn't take a break from rooting. You are just one of a very large group of people that have been blindsided by the galaxys2root website and its rogue developer zedomax. The firmware tools from that site have caused untold problems for people, similar to your problem.
To recover your phone, you need to first flash back to stock. Since you want to root the phone, and ultimately install custom firmware, you should first flash UCKH7 stock plus root package using the one-click downloader which you can get from the guide about how to flash custom binaries without incrementing the flash counter. The link for the guide is in my signature. Read the guide and follow it's directions. That should get you going again. If for some reason you have any trouble, post back here and we'll try to help you out.

Thanks I checked it out..seems like putting the Stock back on might help me. Just so that I understand this better before I do it, am I installing the UCLE5_Stock_Rooted.tar using ODIN and that is enough to get me through.
Thanks

Thanks for stopping by. I did not see your post when I posted my reply to the previous poster..I am so worried that I might screw it up more that I wanted to be doubly sure about this. from what I read, I am doing Step 2c as indicated below. Am I correct?
Thanks
2c.) How to root by flashing Entropy512's Return/Unbrick to Stock, Kernel + Rooted System Package with Modem using Odin3 One-Click Downloader (Windows)
UPDATE: I did download the "Odin3 One-Click Downloader Stock I-777 UCKH7 with Root no BL" package and extracted the file. Double clicked on it with the phone connected and all I see are the words I777- UCKH7 with Root with a lot of empty boxes below. Went to Odin and I see the phone connected (Com has yellow box) but nothing else is ticked off. Clicking Start does not do anything at all.
At my wits end- will not get any sleep tonite if I don't fix it.
Thanks in advance
I had a similar thing happen after trying to make a backup of the stock rom with Rom Manager (Yes, I know now, thanks much.)
If you keep trying new kernels/roms and it never clears up, you're pretty much stuck with wiping data. It won't wipe your sdcard, but more and more apps are sticking their data in the phone's memory rather than on the sdcard, so if you can get a backup at all, you really should.
Source: Was up until 2:30 the other night trying to make my phone work again. The above is a GUESS - it's probable I missed something that creepyncrawly wouldn't.
Ok more progress..turned off the phone and started 'I777UCKH7 OCD With Root.exe". Got the same window with lot of empty boxes. Had turned off the phone by this time and disconnected it. Now, I connected the phone and pressed the volume buttons. Phone goes into Download mode. Now, the Odin3 window has a Com port for the phone. Now I press start and it goes through a bunch of things before it declares "FAIL" in red. What do I do?
Evidently, the zedomax product you originally flashed, or perhaps the siyah kernel that you flashed second, has made some undesired modification. I'd like to know exactly which package you flashed for each one of these first before I suggest which way to start correcting the problem. Can you please post working links for each of the two downloads that you used? You should still be fine, and will be able to recover the phone.

The zedomax rooting kernel you flashed first is for Gingerbread version UCKH7, and was posted last October, shortly after the phone was released. If you had UCKH7 on the phone before you flashed that, it should have booted up fine. Most people I have heard about are able to use that rooting kernel successfully. So I need more information in order to be able to trouble shoot your situation.
First, are you sure your phone is SGH-I777, and not SGH-I727?
What firmware was installed on the phone before you flashed the zedomax kernel?
Has any other modification been done on the phone since or even before you had it?
The second kernel you flashed, the Siyah kernel, is an ICS kernel, version 3.4.2. The phone will not boot if the kernel and the system have different versions installed. So I need as much detailed information as possible so know what to do next.

The phone is SGH-I777 from AT&T. (I'll check the phone when I get home and reconfirm) The phone had the ICS installed (through the Kies update) before I (stupidly) tried the Zedomax Kernel. I just bought the phone new so no other modification had been done. After I had installed the Zedomax I had been able to see CWM if I did the power Volume trick but I cannot do it now since I installed the Siyah.
Hope that helps. Let me know if you need more info.

OK. The phone was new, and most likely came with Gingerbread 2.3.6 UCKK6 installed. You updated it using kies to ICS 4.0.3 UCLE5. Just asking for your confirmation here.
Then you tried to root with zedomax kernel, which is a Gingerbread 2.3.4 UCKH7 kernel, which explains why it flashed successfully, but failed to boot, since you can't have a Gingerbread kernel and an ICS system together. You were able to boot into ClockworkMod Recovery in the kernel though. We can't blame this problem on zedomax. That kernel usually works ok. You started modifying your phone before you were familiar enough with the phone and it's firmware. The error of flashing a Gingerbread kernel onto an ICS system was yours.
Next you flashed the Siyah v3.4.2 ICS kernel. This kernel should be compatible with the UCLE5 system files that are on the phone. It seems to me that the phone should now boot, and I'm not really sure from this sequence what might have been altered that prevented the phone from booting and also prevented the Odin flash back to stock from succeeding. The only thing you have flashed so far is two kernels. No other partitions should have been touched.
What kind of error message do you get when you try to boot into recovery mode using vol+ vol- Pwr?

That seems correct (with regards to the sequence of events of the phone).
The error message is just the words "SAMSUNG GALAXY SII GT1900"..with a huge exclamation at the bottom. It stays like that until I do a battery pull.

Please verify this - the screen says "Samsung Galaxy SII GT-I9100" assuming yours was a typo. Yellow triangle with exclamation mark?
This is what you get when you try to boot the phone normally, and also when you try to enter recovery mode using the three button method, vol+ vol- and power?

Yes, that is correct. It was a typo. I get the exclamation mark when I do the normal boot. I am going to confirm this evening if I get the same error with the 3 button method.

I'm not working from first hand experience, but I'm fairly good at correlating information and making deductions. Something in the sequence of events doesn't add up to me. You're sure you have the I777? You pulled the battery and looked at the label?
At this point any suggestions that I can offer are based on educated speculation. The first thing to try would be to flash an ICS kernel using Odin, but you have already done that. I would suggest that you try that again, but discard the tar you already have and download the tar again, from here. That may be the same place you downloaded it before, not sure. Be sure to use the original USB cable that came with the phone.

So I tried to use odin to root my device. I was following a guide on youtube but XDA won't let me post it. I got to where I run odin while my phone is in download mode. Everything goes according to the video, however, when the phone reboots it freezes at the Samsung splash screen with the yellow ! at the bottom. I've tried putting the phone back in download mode and running it through Odin again but the problem is not fixed. Does anyone know how I would go about fixing this?
Try restocking. If you repartitioned you may be in trouble. Go to cm7 website and follow their instructions.

I made sure the repartition option wasn't selected before I ran odin in both cases. I'm assuming by CM7 you mean cyanogenmod? Sorry for the ignorance, I just want to make sure I'm doing what I need to to get it back in working condition
Dont know why should you go to cm7 website.
Follow this: http://forum.xda-developers.com/showthread.php?t=1103399
use an appropriate kernel for your phone.
Or get a stock kernel and use odin to flash: http://forum.xda-developers.com/showthread.php?t=1075278

I've got no idea what boxhead72 is going on about, but anyway, to be able to help you, we need to know what you've done. Generally, you need to make sure you're flashing a correct ROM/kernel/modem for your device. You also might need to reset to factory settings. But without knowing what you've done, it's impossible to say.
You can find stock ROMs and a guide for I9100 (if that is your phone's model) in Intratech's thread here: [ROM+Guide]Official i9100 Firmwares KG, KH1/2/3/4, KI1/2/3/4/8, KJ1/2 Download.
On the plus side, if you can get to the boot screen, you are far better off than those who get NOTHING. I know it doesn't make you feel that good right now, but if you can get this far, your chances of recovery (if you follow instructions) are near 100%.
If you told us that you get no response at all from the phone when the power button was pressed, you might have room to worry a bit.
Now, not so much. Just take a minute to breathe and read through your steps as outlined in the above mentioned threads. You'll be fine in all likelihood.
Okay, I did some more searching and realized I was on the completely wrong forum... I have the AT&T U.S. I777 Galaxy S2. So exactly what I did was install kies, close out of it, put my phone into download mode, connect it to my computer, install what I assume was an incorrect .tar file using Odin while it was in download mode, let it reboot and am now seeing it hang at the boots screen with the yellow exclamation mark. I wouldn't mind reformatting it if someone could show me how, but I mainly want to use this guide:
http://forum.xda-developers.com/showthread.php?t=1285894
to root it and install CM7. Could I just run odin again and install the .tar file given in these instructions? Or does it not quite work like that? Thanks for all the help you guys are giving by the way!

I don't know anything about that phone, but a quick look in those forums shows:

Thanks for those, I was actually reading through them when I noticed you posted them. I have another problem now though, I ran the stock rom through odin in this guide:
http://forum.xda-developers.com/showthread.php?t=1286432
but it failed in Odin and upon reboot it says firmware upgrade encountered an issue. Please select recovery mode in Kies and try again. I didn't know kies had a recovery mode, but when I connect my phone it always fails to connect. Note that I CAN still get into the download menu, but that's it. At this point is there anything else I can do?

I presume Kies recovery mode is in Kies -> Tools -> Emergency firmware recovery.
I noticed that as well but like I said I cannot connect to Kies so any recovery mode isn't very helpful

I guess if you've done everything on [Guide] How to Prepare Your Phone to Return to the Store or for Warranty Replacement (which is linked at the bottom of the thread I linked earlier), then your next port of call should be Recovering an ATT Galaxy S2 after flashing GT-I9100 Firmware.
I'm an admitted noob, but my hope is that somebody here will take pity and be able to shed some light on what I've done and how to fix it.
Here is a general high-level list of what I've done:
1. I attempted to root my phone with SuperOneClick (I think 2.3.3)
2. It hung one Step #7 (as I recall) for about 10 minutes.
3. I disconnected USB cable and reset the phone - it wouldn't boot
4. Started researching, discovered Recovery Mode, selected reset to factory.
5. Reset appeared successful, but then phone went into reboot loop.
6. Tried to access Recovery Mode again, but this time it came to different screen, saying "Deleting cryption meta data".
7. Tried flashing several times with odin and stock PDA's suggested in this forum.
8. Same behavior, so flashed CWM 4.0.0.2 (unfortunately it was for I9100)
9. Flashed new CWM 5.0.2.3
10. When I enter Recovery mode now and I select the wipe data/factory reset option, it just goes to a hat icon with a circular arrow and stays there.
Like I said, I'm new here and have already given up hope on recovering any useful data on my phone. I just want to get it working again so I don't have to buy a new one.
Thanks in advance!
In you item #10, that's a common mistake. The 5.0.2.3 version does not use the power button to select. Use the home softkey to select and the back softkey to go back.
Try to wipe data/factory reset again from this version of CWM Recovery, and then try flashing the one-click downloader return to stock in the "Return to the store or for warranty replacement" thread stickied in general.
Post your results back here and I'll try to keep an eye out to help, but I won't be on the computer every minute.

This guy is right. The power button is the menu/logo button in that version. The newer version changes that mapping though.
You'll likely need to flash the return to stock image. One of them is already prerooted, too!

Thanks so much for your quick reply and help. I followed the instructions you outlined and all went as outlined. Upon final reboot I'm back at Stage 6 in my original post. The original Samsung logo is back (which is a relief), but so is the incessant rebooting and upon trying to enter Recover Mode, I get the Deleting cryption meta data message and then more reboot loop.
Looking forward to your next suggestion(s) and a little sleep.
Oh, by the way, the wipe data/factory reset within CWM appeared to run properly but made no apparent change.

Tried to answer you this morning, but didn't hit the submit button until a few minutes after 8:00. Let me see if I can do it again.
You did a factory reset and then installed the stock firmware. Now try a factory reset again to see if that will clear the bootloop.
If that does not do it, then you may need to replace another part of the system. We need to know exactly what you flashed for the I9100 while you were trying to fix the original problem (point 8 in your list.) So far, you have flashed everything in the stock UCKH7 firmware except the bootloaders and the param.lfs. You may need to flash param.lfs next to see if that will do it. Is there any chance that what you flashed for the I9100 contained bootloaders?
...........
By the way, having Super OneClick hang on step #6 is a known issue, and the solution is posted in the Super OneClick thread OP as well as in the Library sticky thread in the development section of the I777 forum. If you had been better informed, you could have avoided this problem.

First, you're a true gentleman (assuming 'creepyncrawly' to be male) for sticking with me on this issue - Thanks!
To address your first point, I could't do a factory reset after this most recent flash because that dialog doesn't exist any longer. All I get is the "Deleting cryption meta data" message when I try to enter recover mode.
As for the I9100 flash, I used CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4 first which took me to 4.0.0.2 and then realizing what I'd done, flashed with SGH-I777_ClockworkMod-Recovery_5.0.2.3 which took me to 5.0.2.3, though the I9100 logo still showed during boot.
Thanks again for your help. I will "flash at will" whatever you suggest as at least I feel I'm making progress now.

First, you're a true gentleman (assuming 'creepyncrawly' to be male) for sticking with me on this issue - Thanks!
To address your first point, I could't do a factory reset after this most recent flash because that dialog doesn't exist any longer. All I get is the "Deleting cryption meta data" message when I try to enter recover mode.

The CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4.tar contains only the kernel zImage, so it doesn't flash any of the wrong bootloaders or param.lfs, so no clue there.
However, the message "deleting cryption meta data" seems to be associated with the lfs, so I would suggest that you try flashing just the UCKH7 param.lfs file using Odin3. Go to the Download Repository where you will find the Odin3 flashable tar of the UCKH7 param.lfs.

I successfully flashed the I777 param.lfs from your download repository. Unfortunately, with the same results. I still get the boot loop and when trying to access recover mode I get "Deleting Cryption Meta Data".
Would you suggest I try flashing the secondary boot loader or .pit files?

Well, I had a little extra time tonight so I tried a couple more things after my last post. I went back to the Download Repository and got the secondary boot loader (i777 UCKH7 sbl), flashed with that. No change. Then I got the full set of binaries (I777UCKH7-CL503881-Full), flashed that, and still no change. I think I've tried everything except the .pit and that appears the most risky so I'll await further instruction before trying that.
Am I running out of options at this point?
I had a similiar problem with the deleting meta cache data. I couldn't get it back to working order although I didn't flash pit either. Luckily mine was within 30 days so I gave up and returned for a new one.
Hopefully this deleting meta cache thing can be figured out to see what the cause is. Mine happened from a working rom browsing the web, not from flashing. So I believe it was from aftermarket charger creating some hardware problems to my phone, but not sure what it could have messed up.
If ya can't exchange yours, I hope you figure it out.

I have always understood that if a phone will boot in any way, or show any sign of life, then it can be recovered. Since you can still get into download mode, you should be able to recover your phone. However, since I am not an Android developer, and I don't really understand the low level workings of the phone, I can't offer any more suggestions myself.
You have flashed the complete I777UCKH7 software package including bootloaders and param.lfs, which also rebuilds the csc, so I don't know what is causing the bootloop.
You need to seek the help of someone more experienced. I have two people on xda in mind who specialize in recovering hard bricked phones, and both have a better understanding of the low level workings of the phone.
Adam Outler is a fantastic hardware level developer who published the unbrickable mod for the Galaxy S series of phones, and is currently moving into the Galaxy S II phones. I have heard that he wants an I777 to work on to try to make the unbrickable mod for our phone. He would probably not charge anything since he is using the phone to learn how to do it, but he might keep the phone for a while.
Connexion2005 of Mobile Tech Videos offers hard brick recovery on the Galaxy S and Galaxy S II series of phones. He also has a very good understanding of the low level functions of the phone.
If it was my phone, I would be contacting these two to see if I could get any guidance about how to recover the phone, probably Adam Outler first. I would try to pm them and I would try to get phone numbers and talk with them in person.
You are not hard bricked. And about the pit, that re-partitions the phone. But I don't have enough experience to know if partitioning could cause the problem you are experiencing.
Good luck moving forward.
Any chance flashing a ROM would do the trick...like Unnamed or SHOstock? Just thinking that maybe he's flashed so many things nothing is playing nice anymore. Just a thought, not necessarily a suggestion. ;-)
Also, how long are you letting it sit in boot loop now? It might be taking a while to rebuild everything...?

So, had you rooted and put a custom rom on prior to yours going south, or was it completely stock? What made you think it was related to the aftermarket charger?

Thanks for your thoughts. I had a similar thought last night and so let it sit through the night rebooting. Sure enough, when I checked it (roughly 8 hours) this morning, it was nice and warm, but still rebooting away.

Thanks very much for all your help! I'll try to reach out to these other gentlemen as well.
I've seen other people on these forums with the same problem, but unfortunately, every thread seems to end unresolved. I still hold out hope as I really don't want to eat the cost of the phone and start over.

I figured it was the charger because it was connected when it happened. Was driving home from a Christmas vacation, with maps navigation going, stopped at a rest stop surfing the web. Also on another thread that I read that had a similiar problem, they too thought it was the charger.
And no it was not stock, running unnamed at the time, (though I doubt that is the cause). Like yours I think, I could flash from cwm without success. Wasn't until I flashed stock with stock recovery that I got the deleting meta cache or whatever it is.
Sent from my SAMSUNG-SGH-I777 using XDA App
Any luck so far? I think I'm having the same issues. Although I can flash the stock rom, then a CWM .tar file and get into recovery. But no matter what I do, after boot, the phone starts boot looping.
You can see my thread in the Q&A section.

Hi, did anybody tried this solution??? I'm having the same issue, even tried to contact JTAG unbrick service but these guys told me I'm having a emmc chip failure.
I recently rooted my phone to the latest Siyah version. I noticed the capacitive buttons not working correctly and then I noticed the version I had was for I900. I went into cwm and installed the correct kernel for my phone but it did not fix the problem. I realized after that I didnt clear the cache. So I went into clockwork recovery and tried to fix that but I hit something to cause my phone to go to a black screen and had litle flashes every once in a while. I took out the battery and the galaxy screen with the triangle pops up but then goes to black. If I hit the power button it will show the battery charging button briefly but then goes away.
After all that. My question is can my phone be saved?
Thanks,
Mike

Yes, almost certainly.
First, please confirm the model of your phone. Do you have SGH-I777?
You will need to boot into download mode, and install the stock Gingerbread firmware UCKH7 that the phone originally came with. From that point, you can update or modify the phone as you prefer.
From what you say, it sounds like you need to do a fair amount of reading of the sticky post items such as the faq and guides and elswhere in this forum to get a good foundation of information about the phone and how it works. Understanding makes it much safer to work with your phone.

Yes. I have the I777. When I originally installed the kernel I downloaded it from the I777 section and it was supposed to be a 1 click thing till I realized those little issues of the I900.
I finally got into odin mode and it says its downloading. I can also now see it on my computer. Not sure what its downloading but its better than the black screen i was getting. Been on the downloading screen for 5 minutes or so. Just gonna leave it downloading till it does something or someone tells me something better to do
Thanks for your help!
***Update I downloaded the UCKH7 on to the phone and Odin(on the computer said successful) The phone is still stuck on Downloading... Do not turn off target. I didnt have the auto reboot selected on Odin. Should I try diusconnecting the phone and rebooting with the power button or just wait until it does it? been hung on it for 10 minutes even though the computer said it was done.

Go to the guide how to install custom binaries... which is linked in my signature. Read it untill you understand the basics. It will explain how to use Odin and download mode. Once you understand, flash the UCKH7 stock plus root package that is linked in the guide. This is assuming that you want root and to customize your phone.

if u follow the guide then u prolly have a rooted stock(assuming u used the rooted stock package) which Kies is not friendly with maybe due to having a non-stock kernel, also 2.3.4 is GINGERBEAD. Now if u plan to flash ICS ROM's i suggest forget bout Kies & go back to the guide & learn how to flash a kernel w/ CWM.
Hi all!
I have a Samsung Galaxy S2 which I since a week cannot start. It get stuck on the black/white samsung logo. I cannot enter recovery mode, nothing happens when releasing the power button after pressing volumeup+home+power buttons. I can however reach download mode. I'm not sure what caused this problem, one day I just couldn't start it. I read on forums that many similar problems seem to have occurred when upgrading android but I'm not sure this is the case here (unless the phone made an automatic update while I was asleep). I'm not sure what version of android I'm running, but I'm pretty sure it is at least the ICS.
I would like to hard reset my phone if possible. It seems to be easiest through the recovery mode which I cannot get into.. I read things about Odin, connecting the phone to the computer and downloading android to the phone but haven't quite grasped it. Could anyone explain this option for me or point me in the right direction? Are there other options?
I would appreciate any help, especially since my 1-year warranty expired a month ago!
Best regards,
Marcus

Sounds like the symptoms of a NAND RW corruption. Try this http://forum.xda-developers.com/showthread.php?t=1457458
Hi Marcus,
I had the same problem few days back.
If it's not broken by you trying something fancy, the best solution is to take it to service centre. If you have rooted your device, had installed some custom firmware or are not willing to visit the service centre for some other reason, please read ahead.
All I did was,
Installed USB connectivity drivers through Kies.
Installed ODIN 1.83
Ensured that Kies or any of its processes are not running in background.
Downloaded the official SGS2 firmware
Flashed the firmware through ODIN.
It took around 10 minutes for the full process and I was having my mobile up and running. Using ODIN sounds scary initially if you haven't used it. I have slowly started gaining confidence in it after using it a few times.
Please note that though the process is well proven to be safe, there is still an amount of risk involved.
Sent from my GT-I9100
Download a siyah kernel(like v4.0.1) .tar file and flash through odin.
See if that makes it boot/lets you into recovery.

A couple of things..ensure KIES is not running on your computer in the background. If possible delete it completely. Also ensure your phone is connected to a USB port directly on the computer and not via a hub or to a USB port on a keyboard or something. Odin is a finicky s/w..so..
Also, try different versions. If v1.85 doesn't work try v3.4

Lol at underlining. if you flash a custom kernel like siyah, you'll be rooted and get CWM. Using that you can install a custom ROM.
Sent from my GT-I9100 using xda app-developers app
And youll be safe from the 4.0.4 brickbug if you flash siyah.
You flash a kernel for various reasons like it has emmc cap disabled,you can tweak it etc.
You can flash siyah kernel and stop there.Or you can move onto a custom rom.
Whatever,when its done-backup your efs and make a nand backup.
And yesterday I was downgrading my wifes phone onto 4.0.3.I was using odin and kept getting "failed".After 3 attempts I realised I hadnt put the phone into download mode..........how stupids that......lol
hi there, just wondering, after Flashing the stock firmware through ODIN, do you lose everything in your phone? i need to get all the notes that I have in my phone (notes from the samsung stock apps). I dont have any external sd card in the phone. thanks in advance for the reply.

Hi there sir,
Has the problem solved ? Care to share the solution ?
Thanks.
i had the same exact problem, i tried flashing with odin n stock firmware but stuck in NAND write start, i didnt try flashing with PIT & repartition though, i couldnt be bothered anymore, so i took it to samsung service plaza, they told me the problem is in the main PCB (hardware issue), so all they did was replace that n it got fixed! i didnt pay because it's still under contract/ carrier warranty

I had a similar problem, stuck at boot with Biftor v12, which happened after I tried to update SuperSU binary through CWM/TWRP. I don't know why it stuck at boot and why it wouldn't reboot to Recovery. Download mode was still working, so I had no choice but to flash new kernel through ODIN and see if it works.
So if your symptoms sound similar to mine, here's what I did to be able to boot again:
I REPEAT, SIMILAR TO MINE. MY SOLUTION MIGHT NOT NECESSARILY APPLY TO YOURS.
1. Download a suitable kernel in tar.md5 format. I used PhilZ-cwm6 v4.93.6 for XWLSN firmware (see OP http://forum.xda-developers.com/showthread.php?t=1877270)
2. Download ODIN, if you don't have it, found here http://forum.xda-developers.com/showthread.php?t=2189539
3. Once installed, boot your phone in Download mode by pressing Vol Down+Home+Power together until you see a warning dialog. Press Vol UP to get into download mode.
4. Make sure ODIN is running, and NO KIES processes are running.
5. Connect your phone with USB cable to your PC.
6. In ODIN, you should see a COM port with yellow background.
7. Click the PDA button ONLY.
8. Select the kernel file you downloaded.
9. Press Start and nothing else.
10. If everything went as expected, your phone should reboot after a while with a working Recovery.
Only do the steps if you are absolutely sure. This worked for me, and I hope it gives some tips for your problem as well.

I have the exact same problem with SuperSU on my rooted Galaxy S2. I updated the SuperSU app, and when I opened it, it recommended me to update the binary, I selected the CWM/TWRP option and then my phone tried to reboot but is now stuck. It can only access download mode.
In doing the process above, you only flashed the kernel? Did this totally work? And all your apps/messages were left intact on your phone?
Any help is appreciated.

when ur updating the binary u should always choose the 'Normal' thing instead of the 'CWM/TWRP' one ma8
if u flash a kernel it will not delete anything on ur phone, all u have to do is to select the right kernel like 'Philz' for example (if ur on a stock JB firmware) and flash the same through 'ODIN' and reboot ur phone

Thanks for your help. I've originally had Jeboo 1.2 kernel on my phone and tried to reflash that again through Odin. It passed, however I'm still encountering the same problem of the bootloop.
Would flashing a different kernel help? I'm on stock JB firmware but with a Jeboo kernel. I am happy to try another kernel (if that would not brick my phone)
Do you have any other suggestions to help me solve this?
Again thanks for your help

You could try flashing hawkerpaul's kernel wiper first and then install another stock kernel like PhilZ or Apollo, and see if that helps.
Neat Rom lite,suddenly struck in boot loop after 1 month of operation.
Dear All,
I have installed the "I9100XWLSZ_NeatROM_Lite_v5.0.1" custom rom and after 1 month of successful usage, today suddenly the phone was dead.(probably due to autoupdates over wifi) . I tried to reboot, but didnt. Tried to restart but got stuck in the logo screen with yellow triangle.
Tried to enter recovery mode, but no use. Only download mode is possible.
Tried to flash the stock rom using odin, but no use, Nand write failed.
Can somebody help me how to come out of this situation. Shall I install a different kernal and see?
Regards,
Maka11
Hi Guys,
Sorry to bother you with this, but I'm out of ideas...
I decided to root my i9100 using this guide9.
As I was doing this, the recovery rom would reboot when using the volume buttons to navigate (only on the first "page") - This was easily worked around by using the touchscreen, but now I'm wondering if this was the start of my issues...
I applied the SU busy box installer, and got root. I installed rom manager, and noticed that it seemed to lock up when doing certain things. I put this down to CWM saying there was no official mod for the i9100.
The next day I decided to try and install a CM10.1 nightly, so I took a backup, wiped cache and data, and applied the rom and gapps.
When I rebooted, the phone wouldn't finished booting, it just sat at the initial logo screen.
After that, I tried following this recovery guide but the odin flash failed at around 80% (I retried and the same happened again).
Since then I've had difficulty getting in to recovery mode. I've tried flashing various stock roms with odin, and trying to restore with Kies.
In Kies I get as far as it conencting to the phone in download mode, but it pops up a "notice" in a foreign language - presumably Korean (and I can't copy the text to even attempt a google translation).
I tried flashing Siyah-s2-v5.0.1 to get a different recovery - that seemed to have a garbled progress bar, before hanging when I tried to wipe /data again.
When I use odin to flash a stock rom - is it supposed to restore absolutely everything? I'm not sure how I'm still getting problems if this is the case. Any ideas on what to try next?
(The current stock rom I'm try ing to use is this one)
Let me know if I'm missing any info, and thanks in advance for any help.
Using rom manager would have been the start of your problems-not the temp cwm recovery in the rooting guide.
If you can boot into download mode then I would download LP7 stock rom, disable kies and flash that with Odin.

Thanks for the reply.
Rom manager didn't work properly for me, so I stopped using it. I used the temp cwm recovery to install the CM nightly.
I can boot in to download mode, but I've already tried an LP7 rom, - as with the others, it doesn't boot.
Any ideas on how to tell why it isn't booting? logcat doesn't seem to want to to work. Not sure if it's broken / too early in the boot process / etc

I9100 right?
Try this:
- Download this ROM.
- Kies installed? uninstall it, re install it. Close it all up with Task manager (3 or 4 applications running).
- Flash ROM via Odin (CSC, MODEM, PHONE).
- If that doesn't fly, try another usb port & usb cable. Another PC would also be recommended.
- Repeat the process.
- Still no luck? try flashing a previous siyah version.
- No go? repeat all the above.
- Let us know how you did.

Thanks, I'll give it a go. (Will take a while for the file to download from hotfile...).
Are odin images for stock roms supposed to restore the stock recovery, or do they leave that alone?

As a matter of interest, how far did you go with Phistachios repair guide.

Focus on getting a ROM to boot.
That ROM will install stock recovery.

For some reason, I can't get Odin to flash that rom - it just hands for a while at the start of data.img, before saying "Complete(Write) operation failed."
There a .pit file in the archive, although the link says not to repartition (so I didn't).
Some roms seem to get written, some don't, I'm not sure why...

Odin failed about 80% through flashing (step 4, after taking the ICS steps). I tried flashing the kernel afterwards, which flashed, but didn't help with my boot issues.

Of course, I was just trying to get a better understanding of how things work - I'd settle for anything booting right now.
I was meaning how far did you go with his guide.He says (near the end) to flash a bootloader/kernel/rom.
You can try everything in his guide, but understand about the risks involved with pit and bootloaders.

He's right.
Keep trying, consider pit files & bootloaders as a last resort.
Tried everything?
Used another usb cable for the flash? tried in another PC? tried in a laptop?
Are you sure kies is all shut down?
I've read about so many people having the same issue than you, they keep on flashing as in trial & error and most times they come out winners.
GL!

I guess I'll keep at it then.
I'd tried another cable with kies shut down. Just tried a different machine, and flashed the ROM you suggested with heimdall. It flashed without complaining (unlike odin), but I'm still getting a boot loop.
Looking at the initial recovery guide I was following - I suspect that I might've flashed the bootloader (the guide shows in bold which file goes in which box, so I probably loaded them all). Maybe this is the source of my troubles...
I also noticed that heimdall can pull data from the phone too - if I can pull and mount these, am I likely to find any useful log files?
For completeness (and anyone else who finds themselves with the same issue): It seems I hit the EMMC brick bug, which rendered some of my EMMC storage unusable.
This helpful chap came up with a workaround to partition around the dead space. (Please read the post carefully and make sure this really is your problem before flashing!)
That method will let you know what part of your memory is corrupted. It's done via recovery as far as I remember.
Did you bring your device back to life?

Yes, that's right. IIRC, I flashed a working recovery with Odin, then did most of the work from adb shell.
I got my device back to life for the most part. I get the occasional hang but haven't investigated much (have since bought a Nexus 4, so not using the S2 so much).
Just thought I'd share for the next poor soul who has the same problem
