[Q] Won't get past boot! - Galaxy S II Q&A, Help & Troubleshooting

So I've been on CM9 since October, everything has been all well and good! Today I decided I wanted to flash a unbranded GS2 ICS ROM onto my phone so I could then update via KIES to the new JellyBean one. But now my phone will not go past the boot logo since I flashed I9100XWLPT via ODIN in the PDA section just as the guide told me. The boot logo moves but will not go past it. I have flashed a new kernel, I then tried Syiah Kernel. Now I've reflashed Cyanogen mod 9 via CWM and it is doing the same thing. The boot animation just moves forever. Can anyone help?

yes flash jb straight up.
Sent from the little guy

Wipe data/cache and dalvik-cache then re-flash a JB ROM (since you want to use Jelly bean) via Odin. You can get JB Roms from here

I've wiped all caches then flashed the JB SII ROM and still the same problem, it boots up to the samsung logo then just replays it over and over again without getting into the phone

And factory reset does nothing?
Flash this. See how you do.
PS: Flash only CODE, PHONE and CSC.

Boot Loop, Can't Access Recovery Mode

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.

Stock ROM doesnt work

Hi there.
I had a custom rom on my Galaxy S3, and I wanted to go back to stock rom. Before I had a custom rom, I checked my product code, just in case if I ever wanted to flash stock rom. So, I downloaded a stock rom from sammobile and flashed it with Odin. I had a successful flash, but when the phone rebooted, it stopped at the samsung logo and it's like that every time I turn on the phone.
I aslo tried to flash it with the same rom, but from a different site (androidfirmwares), but every time I treid to do that, Odin crashed ( Odin downloader has stopped working).
I can't even boot into CWR to flash any custom rom, cuz it's gone. There is only stock recovery.
Please help
Which Rom were you trying to flash when this happened, and give details of how you flashed please

if you are getting stuck on the boot screen after you flashed the stock rom this always works..go to recovery do a data reset and wipe cache.
this is really weird and a stupid thing I did when I was completely new to android..a little over a month ago.I got stuck on the boot screen and accidentally flash CF-Root instead of the stock firmware..when the phone rebooted it worked just fine.I dont think its supposed to work that way..:S

[Q] CM7 Bootloop

Well, this is what happened.
My phone was using cMiui 4.1.2 with the default kernel, and this morning I tried to flash CM7. I wiped everything as always before flashing, after I pushed reboot system and it got stuck in the "Galaxy s2" screen and keeps turning on and off endlessly.
I pulled out the battery, try to get back into recovery, but it hadn't been a successful attempt.
I stayed claim and flash back to stock 4.0.4 via Odin, god-bless I made it through.
I installed a custom kernel and flash to CM9 for temporarily use. Now I don't know what to do.
I really want to try the taste of CM7, please help.
Edit: I also tried various way of flashing, such as flash a codeworkx kernel before flashing, and flash back into GB 2.3.5 before flashing CM7, both didn't work out
it was making me crazy for weeks and here is the solution i found 5 minutes ago :
when it gets bootloop
go to download mod and flash siyah 2.6.14 via odin!
then it boots.

[Q] I9100 bootloop after flashing stock 4.0.3

Hi all,
Having a strange issue. After giving my phone in for servicing, Samsung wiped it and put 2.3.6 Gingerbread back on. Naturally, I got a stock 4.0.3 file to flash (XXLPQ at first) and did so (well-versed with all of this). However, ever since that first flash, the phone's been stuck in a bootloop, usually at the "Installing applications" screen, but sometimes just a normal bootloop at splash. I've re-flashed with different stock ROMs, followed the soft-brick guide and flashed the bootloader and kernel, nothing's working. The first flash was clean, but after that I haven't been able to access recovery, only DL mode, so no way to wipe first.
Any thoughts?
Thanks
Change CSC it will wipe your data or XXLSJ with all components(PDA,PHONE,CSC)

[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

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:
