Search this forum for stock rom & flash it via odin by putting mobile in download mode by pressing power + middle + volume down!!

Then your mobile should work!!

After that search for clockwork mod & find appropriate version for you & flash it again via odin!!

I did all the procedure and my phone worked perfectly, using XXKG5 firmware. Everything went well, my phone was good, fast, basically perfect! But after 4 hours, it get stuck again like before, so I had no choice but to restart the phone. When I did it hanged again like before...boot loop!

I tried Recovery mode but this time it was all red, cannot mount, blah blah, E: something mount, copying media failed, and it hangs when I reset to factory setting. So what I did, I tried to to go download mode and tried to flash from Odin (Kies service is ended), but it get stuck! I left it for an hour and nothing happened. So I restarted the phone. The error comes as follows:

[Mobile image]---[Yellow triangle]---[Computer image]

"Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."

Please advice.

Stopped Boot Loop. Now Frozen at Startup.

[never mind problem fixed!!]

I initially had the boot loop problem after trying to flash lite'ning rom. Then after following the instructions on this thread my phone goes to the 'Samsung Galaxy SII GT-19100 Screen' (black and white) and just freezes there. I can only turn off the phone my removing the battery I can go to recovery/download mode also. I've tried wiping and then flashing the stock rom a couple of times already and still it's stuck at this screen upon start up. Any suggestions?

[Q] Samsung Galaxy S2 - Bootloop stuck, no recovery mode but do have download mode!

Hello there!

I have read through all the Boot loop posts before anyone asks!

My phone is stuck on the Samsung galaxy s2 boot up with the yellow triangle and the black "!" inside (Boot loop). This happened after flashing the wrong kernel on the device first time. Here is the thing, no matter how many times I try to flash the Kernel which I think is "KH1" (99% sure) in download mode with Odin and all the right drivers installed right from Kies, it still won't work! I've tried stock kernels, insecure kernels... you name it I've tried it!

The phone it's self will go into DOWNLOAD mode (which works fine) , but not RECOVERY MODE at all! :@

I have been trying for days to fix it, but nothing on here will work.

Please some one get back to me and try to help me fix this problem as I want to use my galaxy s2 again. :/

Thanks, Sam

Okay, may not be in the good place... tried to search a bit around but didn't find anything relevant >_>

Problem history is now getting quite long so I'm gonna get it tidy :

Installed Litening Rom (I think it was version 2 or 3) a few weeks ago with Odin 1.85

Got some random crashes, thought last version would fix it, flashed to Litening 6.1 (again with Odin 1.85), that was yesterday evening

Everything runs smoothly, plug it to AC, leave it charge for the night

Wake up with alarm, surprise : no SIM service. Wasn't a carrier failure as I got a second smartphone with the same carrier that was still working. Tried swapping SIM cards, but still isn't recognized... or whatever it is (when I went to "mobile networks" [not sure about the english term since I'm using a french version], I got a message like "no sim inserted")

Since I thought it was a Litening Rom failure, I tried to flash it to Cyanogen (and it was a "good opportunity" to test it)

Read thoroughly the wiki about flashing, copied the rom in my EXTERNAL SD and got into Recovery mode with Clockworkmod

Followed the manual up to point 4 of "Method via Recovery" and DIDN'T chose to backup since I thought my datas were safe 'cause I backed them up already on my comp

Wiped as mentionned, reached the "Choose Zip from sdcard". And then, first problem, I couldn't access my external SD card... since I noticed the nice "mount SD" on it, I mounted the SD and copied the .zip in the "sdcard"

Tried installing it... error.

Tried to reboot, looping boot

I then tried various things... can't remember all of them, but here is the situation :

- I can't boot, pressing the power button gets me the "Samsung Galaxy S II I9100" with the yellow triangle for about a few seconds before getting me to ClockworkMod

- Recovery gets me into ClockworkMod

- I can mount the device via recovery

- Download gets me into ODIN download mode. Even though it's marked Odin, I can't get it to appear into Odin PC Manager (v1.85 as usual)

- In download mode, I can get something into Heimdall... but I don't have any .tar working right at the moment. Litening 6.1 one is getting me a "Firmware.xml is missing from the package" and Cyanogen mod (zip file) gets me a "Tar header contained an invalid file size" error.

I hope I've detailed my problem enough... does anyone got an idea from now on ?

Awesome Thanks You!!!! Saved my butt!!! Can anyone help me Root My Galaxy S II? I'm stuck at some hat logo when I choose to install from sd card where I have the custom rom. it's at the root level so I believe I've done everything riogh, or totally wrong. I can reformat to factory if necessary, just want the darn thing rooted for a few apps I use.

Thanks!!!

some details:

If someone could PLEASE tell me what up with my Galaxy S II I did all the steps in odin to prepare for root...I don't care about any particualr roms per-say, just want to run a few apps that require root. and when I select install from sd card (which the file are on at the root level of card (I'm using su-3.0.5-efgh-signed.zip) it just hangs at this lil hat icon....how can I proceed to root this? It is the Samsung Galazy S II SGH-1777, Android Version 2.3.4, Baseband version I777UCKH7, kernel version 2.6.35.7, build number GINGERBREAD.UCKH7

How can I root this puppy? I got it yesterday when my Infuse just died on me. ATT didn't have any in stock so the have me a Galazy s 2 instead . All I wanna do is root it if someone can tell me the best/easiest way to do so without bricking.

Thanks XDA!!!!

I have the same problem with my Galaxy S2 but I haven't managed to fix it. The only way to use my phone is with the Stock ROM (I miss several features on MIUI u.u). I've read the entire post and tried everything. From flashing the stock ROM/Kernel with the repartition ticked and the .pit file then installing a CWM kernel and it boots on CWM but when I flash MIUI, Galnet MIUI, CM7.1 it just goes into the restart loop at the "Samsung Galaxy SII" screen with the yellow triangle. Is there anything else I should do? It all began when I tried to install CM 7.1 by flashing it 2 times and wiping data, sdcard, dalvik cache, etc. Now it won't let me boot anything but the stock rom by repartitioning. Any suggestion bros?

[Galaxy S II Q&A, Help & Troubleshooting] mayhem_vader:
Folks,

I just joined due to the huge problem that I encounter. I just bought my Samsung Galaxy S II a week ago. Two days ago, I left it charging overnight, and bam! it wouldn't boot.

The phone powers up and freezes on the SAMSUNG logo. I tried VOL UP + HOME + POWER to go into recovery mode, which does not work.

However, I can go into download mode by VOL DOWN + HOME + POWER.

I am not at all experienced at flashing, rooting or etc. But I have been reading forums for two days now, still found no solution to my problem. A detailed description is this:

The ROM of my 'soft-bricked' phone was a Turkish region stock ROM, most probably I9100XWKF3. (I am not very sure, but don't think this would matter much) I downloaded different versions of Odin, ranging from 1.3 to 1.85. I also downloaded some stock firmware from samfirmware.com, which are I9100XWKF3 and I9100XWKG1.

I tried flashing first the I9100XWKG1, which is a single PDA. I unchecked 'Re-Partition'. I tried on Odin 1.3, 1.7, 1.85. No result, it always gets stuck on BOOT.BIN.

Then I tried flashing I9100XWKF3, which has 5 files (CODE, EFS, MULTI-CSC, KERNEL, MODEM). There I put CODE to the PDA field, MULTI-CSC to the CSC field and MODEM to the PHONE field in ODIN, I also included the EXT4 pit file and checked Re-Partition. No result, Odin would get stuck on 'DO NOT TURN OF TARGET' in the partition subsection. When I uncheck and give it another try, it again gets stuck on BOOT.BIN.

I tried disconnecting the phone, removing the battery and waiting a while, giving a try to different usb ports and even to a different pc. I also tried many versions of the Odin, still no result.

I need help with this one, any help would be much appreciated. :(

Sorry if this is a repost but I couldn't find the solution to this one around.

[Galaxy S II Q&A, Help & Troubleshooting] mayhem_vader:
There is no return policy, where I live, in all kinds of shops. Actually I paid a visit to the shop, and found out that they would forward the device to an official Samsung technical center, which would take a month to get back, as they said.

Since the download mode works, I wanted to give it a try.

Still, any help would be much appreciated.

[Galaxy S II Q&A, Help & Troubleshooting] mayhem_vader:
Thank you mr_tris,

I can already get into download mode. My problem is not being able to flash stock firmware.

Guys, i need help...
[Galaxy S II Q&A, Help & Troubleshooting] qureyoon:
If you can go to Download mode then search for your official firmware (see here: http://xdaforums.com/showthread.php?t=1075278)

And flash as usual using Odin.

It will bring back your phone to the usual one (without root etc.)

You can flash other official firmwares as well.

Mine was 2.3.3 DXKI2 previously, my country have not released the 2.3.5 officially, so I just took the latest XWKI8 and flashed it.
[Galaxy S II Q&A, Help & Troubleshooting] mayhem_vader:
Thank you qureyoon, but I already tried all these, with numerous official firmware packages. I talked about this in my first post, maybe I wasn't clear. ANY flashing via Odin stucks at BOOT.BIN. I can't flash KERNEL either, it gets stuck at NAND WRITE START and I wait around 30 minutes (which is huge) or so then I give up.

:( :( :(

Edit : Would it help if I ticked the 'Phone Bootloader Update' on Odin, or would I just mess things up???

Ugh..

So I had the boot loop problem, then I attempted to do this flashing when it got stuck on the flashing (under the "o" in not).

I am assuming this is because after I rooted I turned off debug mode to load some stuff to SD and didnt turn it back on, I DONT THINK. I can't be sure.

I'm freakin out at this point. Its 8am and i've been at this since 3am.

Anyone have any suggestions? I'm afraid to unplug the phone...

[Galaxy S II Q&A, Help & Troubleshooting] neobirdrio:
Simple! What rom u flashed? Miui? Cm? If so, after flashing, u got boot loop there, that a nice boot animation u ever have dude. Haha.

Simple way, boot into recovery, full wipe, then flash any kernel that compatible with the rom. Your phone will successfully boot up as usual.
[Galaxy S II Q&A, Help & Troubleshooting] neobirdrio:
If your phone running stock rom and rooted, what file u flashed then? Rom? Themes? Kernel? Or any oddon? If you flash something not compatible with the rom, then for sure u got boot loop there. If you flash custom rom, make sure full wipe. Same goes to kernel, kernel no need to full wipe, but u need to mount the system. Sometime your cwm doesnt load the system so u need to check it. How to know the system loaded? It should be like this = unmount / system

This mean your system currently loaded. Then ur safe to flash any kernel.
