Boot Loop, Can't Access Recovery Mode - Galaxy S II Q&A, Help & Troubleshooting

After hours of searching and flashing roms I've decided to give in and start a thread:
I downloaded a jelly bean rom, using CWM, It then preceded to install. Stupidly I didn't opt to factory reset and wipe everything (I thought CWM would take me to recovery mode before flashing the rom). That left my phone in a boot loop. I then flashed a stock rom (4.0.3) but it still was boot looping.
From the past few hours I've spent in these forums it seems by best bet it to flash a rom that has all the parts (phone, csc, modem etc) but I can't find one anywhere. Does anyone know where I can find one or of any way of getting into recovery mode? Any help would be much appreciated, thanks.
Device: Samsung Galaxy S II - UK - O2 (Was running CM9 before I ruined everything).

Hi mate,
The best thing for you to do is enter download mode (hold volume down+home key+power) and connect to Odin and flash an official firmware again
I know that XWLP7 contains everything in the 1 file as this is the one I flashed. Simply place the file in PDA section of Odin.
check out this thread:

Good luck mate!!

Thanks for the reply. I had tried flashing a stock rom a while back but to no avail. A couple tries later and it worked - I'm now running Jelly Bean but more importantly I have a working phone!
For anyone having similar problems (which seemed to be a few). Just keep flashing stock roms and remove the battery a few times, cross your fingers and at some point you should be able to get into recovery mode to do a proper install. Also I was mistaken about it being a boot loop, I was actually just stuck on the starup, galaxy s II, screen.
But anyways, cheers for your help.

[Q] Samsung Galaxy Tab 10.1 bricked?

Hi I hope someone can help me. I have searched this forum but could not find a similar situation to what I ended up in...
I tried to install a custom ROM on my Galaxy Tab 10.1 using the CWM/Odin.
This seemed succesful but was not, it did not start but was stuck in the Samsung logo.
So I tried entering the CWM and download and install an original Samsung ROM. I can get it into CWM, but CWM cannot enter the download mode only the other mode.
In this mode all options are available:
- reboot
- apply update from SD card
- wipe data/factory reset
- wipe cache partition
All options have been tried without any luck. In the update from SD card it only shows ...
or Error opening /data/media: no such file or directory
Any ideas how I could get this directory back or put a ROM on the Samsung in this situation.
Odin does see the Galaxy but as I cannot get it into Download mode I am unable to download anything to it.
All or any suggestions are very welcome!
1. CWM (Clockworkmod) =! Odin.
In the beginning, you don't have CWM installed. You install CWM, by flashing CWM on your Phone with odin.
Odin is the Windows Programm, that is used to flash Recoveries/ROM's/Kernels onto your device.
2. it seems, that you still have the default Samsung recovery installed, that meand CWM is not yet flashed on your device.
If the flashing process was succesful (I suppose it was done with odin), but you can't get past the Samsung logo, that means, you probably flashed a rom, that isn't made for your device(ex. a GTab 10.1v Rom).
If you DID flash a wrong rom, then you probably ****ed up the partition table and removed the Download Mode(Odin Mode). Strange thing is, that you still have the Stock recovery.
Could you please redirect us to the rom you downloaded?
Also, did you flash with a repartition on and/or a .pit file?
hi Kaukassus,
thanks for the reply.
OK I checked the files and what I did.
I think I totaly screwed this up. It was a theme I tried to install the AOSP_HC_v1.3_3G+KI1.
I rooted the Tab. So first when the Tab was still functioning installed it on the TAB via USB.
Than tried to install this via update from SD card.
This appeared to work initially. But hung at the start.
After that I tried (via Power Volume Up) wipe data/factory reset.
No luck.
After that I tried wipe cache partition followed by wipe data/factory reset.
And this is what I got now..
Bad news is the Tab was/is a X-mas present and I managed to screw it up even before I officially got it !-(
The valuable lesson you're learning is that you need to be aware exactly what things you're flashing and their compatibility with your device and the software it's running.
You haven't mentioned what specific device you're using or the specific things you've tried to flash (as kaukassus pointed out, direct links to threads where you got the files you tried to flash are best). Not sure if you're aware but not all GT 10.1's are equal; there are several models out there and each and every ROM is specific to a particular device. Verizon LTE GT 10.1's like mine can't take ROMs from any other device for example, it's likely that the new T-Mobile 4G one's wont be able to trade ROMs with Verizon ones . . you get the point.
When you say you installed via USB what exactly did you mean? If you simply copied a zip file via USB to the tab to flash in recovery mode that's not installing; the flashing from recovery may be but the file copy operation is not. If on the other hand you pushed things via ADB or you flash using Odin software then that's a different story.
Best thing to do at this point is to properly identify your device, look for a stock recovery image for Odin and flash that via Odin to your device. At that point you can start from scratch again to build what you want.
Thanks Muzzy996.
You are right. I was in a rush and should have taken more time.
However I am getting somewhere. Managed to get in download mode twice today, don't ask me how. This Tab just will not go into download mode!
However I did not have the stock ROM ready to be installed.
Will keep you updated.
i have the same problem. i just rooted my device was going to overclock. decided to save my rom with rom manager. saved it device went to reboot now the samsung galaxy 10.1 shows up screen goes dim then shuts off, and will cont. do this. i can get into download mode but recovery will not work. is there anyway to download my stock rom. im using verizion 4g 10.1 any help would be great, btw sorry to thread jack
Problem solved.
Managed to get it in download mode again and install stock rom via Odin.
Appeared to work fine. But kep switching off, even after full night of charging.
This morning Tab was dead after recharging whole night..
Got it back on by holding volume down and power button down.
i found a stock rom and im trying to upload it via odin, however odin does not find my tab? any ideas. btw congrats on getting ur tab back
I crashed both my I9000 (galaxy s) flashing custom roms and my tab 10.1 (editing some system files) both ended up just looping but managed to get both back. I purchased a small connector of ebay £1.59 that has just a resistor accross pins 4&5 331k I think anyway plugging this into most samsung devices boots them into download mode. Even before getting my resistor I managed to get things working I think that you'd have to be properly unlucky to really brick a samsung I've flashed both my devices with all sorts of crap with my little resistor I just reset them with ease.

[Q] Galaxy S 2 Boot Error

Hi Everyone! just a rookie here in need of a bit of advice.
I'm a Galaxy S II I9100 owner and have my phone rooted and all setup with custom roms and been comfortable with flashing for some time now. My ROM of choice recently was Vanilla Rootbox and have to say the ROM has been fantastic with very few bugs to report. Last night i recieved the OTA update via Goo Manager for Vanilla Rootbox 3.4. I downloaded the full update over wifi and flashed with all wipes no worries. Next step was to flash the latest GAPPS and i figured there would be nothing wrong with flashing the GAPPS zip i had on my sd card that i had downloaded the last time i was notified of a GAPPS update via Goo manager as well. After flashing, wiping everything and rebooting again. My phone then booted up to a series of dialog boxes indicating that many google processes had stopped functioning. apps.google.com etc etc. A similar error has been reported in the Vanilla Rootbox thread by another user but i wasnt able to report this bug their either because my post count is too low to post in a development forum. So after seeing this error i rebooted into recovery to flash my last backup but CWM recovery came back with an error messaging stating it couldnt mount either ext or int sdcard. i did a factory reset which made no difference to the problem whatsoever. I then downloaded ODIN and the latest stock ICS Rom and flashed it via ODIN with no reported errors. My phone now boots through the optus boot animation and is stuck at the Galaxy S 2 screen with the flashing red and yellow animation over the S. If i turn off the phone with the power button, the phone turns off and immediately starts again and gets stuck at the flashing s screen. I've taken the battery sim and ext sd card out and put it all back in only for the problem to persist.
If anyone could help me there's a donation and my thanks in it!
Much appreciated
Nick
tried to re flash another stock ROM?
If so, tried factory reset the phone after the flash?
As long as you can get to DL mode, you are good to keep on flashing till you are up & running.
And then you got this
Remember to update your kies and make sure you close it all up before flashing with odin. If you are in 4.0.4 beware of the brick bug.

Kies has never been installed on this computer but i did use the usb drivers mentioned in the soft brick recovery guide you linked. I used some information from the guide to flash this stock rom but i couldnt flash or wipe the partition because im unsure where to get the .PIT file required? i cant get past the boot animation so no factory reset possible and yes i can still get into download mode!

wow wow, leave pit files alone for now, they are nasty.
What stock ROM did you flash? 4.0.4 or 4.0.3?
You can factory reset via recovery mode.
Try installing kies anyway, it can't never hurt. Just make sure all applications are closed before you re-flash.
here's jb leak, might help:

[Q] Odin/Recovery Install Failing

Device: AT&T Galaxy S III (SGH-I747) Rooted
ROM: Cyanogenmod 11
I have had my phone rooted and running a custom ROM for a few months now and I have decided that I no longer want to run a custom ROM. I looked up how to go back to stock ROM and everything said to: wipe cache and do a factory reset, download latest stock ROM off of Samsung's firmware website and flash the ROM from Odin. Every time that I did this, it would always fail even if i tried to install from recovery mode. I tried a few more times and it still didn't work. One post said that it was because TWRP, i downloaded and installed the stock recovery (which was the only successful install) and the other installs still didn't work through odin or recovery mode.
Is there anything that I am doing wrong, am I leaving a step out, or is something just flat out wrong with my device?
Assistance would be greatly appreciated!

[Q] I9300 stuck at samsung logo, even after installing stock rom

Hello everyone,
I had CM11 installed on my Samsung galaxy S3 I9300. But I wanted to trade my phone with my dads and he wanted the simple stock rom (Android 4.3). I tried flashing the stock rom on it which went good until the last step when it should reboot itself. But i'm stuck at the samsung logo, I tried everything (pulling out battery, rebooting it, install stock rom again,...).
And I even can't get in recovery mode. The only possible mode in can get in is download mode. What can the problem be? Have I done something wrong? Should I try to install another stock rom from another country? Is there another way to get in recovery mode? I am from Belgium and I can't find the "Belgian stock rom", so I tried installing it from the Netherlands, is that the problem?
Thanks already.
What is the filename of the stock ROM you flashed and which options did you select in Odin?

First thing you should always do after flashing stock rom or any rom that causes a boot loop is to boot into recovery and factory reset then wipe cache this solves 90% of bootloops. Now I know you said you can't get into recovery so try flashing a custom recovery with odin then try booting into that and then factory reset.

[Q] Phone won't get past recovery

I'm trying to fix an ace gt-s5839i (rooted with stock ROM) that won't boot up, it always goes straight to recovery.
I've searched for fixes on this forum (and others) and the fixes i have tried so far have not worked, these include flashing a new recovery (clockwork), flashing a whole new custom ROM (razordroid and CM) and flashing stock ROM through Odin, also it won't even let me wipe data through recovery as it will just stick on formatting data.
Any idea what is up and how i can fix it? The phone belongs to a relative of mine and he said he woke up one day and the phone was in bootloop, he took out the battery and put it back it back in and ever since then it just goes straight to recovery.

Ok , I did mention troubleshooting method for similar cases like you in many posts here mate ,, Just get yourself stock s5830i firmware compatible with your Region/Carrier and make a wipe / split packages with the help of splitfus2 or simply use one of the pre-made packages >> Follow my instruction @post#4 from the line :"1. Download one of the newest ,,," to the end of the post .
btw razordroid was obsolete and buggy at the best of the times anyway , try newer/more stable from development sub forums .
After resolving your boot loop and partition issues you may flash your newer s5839i stock fw from i,e: sammobile database on top of your s5830i over Odin ( normal flashing procedure ).
Hope I did Help you
