Root (CF-Kernel) --> Stock Firmware --> S2 just booting, no reacrtion - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I installed the CF-Kernel to my S2. After that, I installed the resurrection remix rom.
Now I wanted to install the stock firmware again, so I downloaded the stock rom, where I thought, that this is the one that my S2 had after starting it the first time.
I installed this official firmware: http://androidfirmwares.net/PhoneFirmware/Download/35
DBT seems to be the right for my german S2, and it had the number "XWLP7"
It's also a Galaxy S2 i9100. Not the G version.
Could someone please help me out? My S2 is just booting, it won't start. It's just showing the official boot screen for over 30 minutes now. Even a reinstall via odin didn't work.
Thanks a lot in advance!

when changing from a custom rom to a stock rom, it is essential to perform a wipe / factory reset. shut down the phone (if you are still booting ) and boot into recovery and do the wipes from there, format data, cache, dalvik cache and fix permissions.

[Q] Can I fix Galaxy SII after a failed rooting?

Hi,
I updated my Galaxy SII to ICS (BVLPB) via Kies and I lost the previews root, now I tried to root it again with method from Chainfire but with no luck and my phone don't start anymore. I tried to put back the stock kernel from intratech but still with no luck.
I can still go to download mode or recovery mode, but this is the only thing I can do.
Now the question is: What can I do to fix my phone, can I fix it?
Thank you very much.
yes you can
go into download mode use fusdownloader to get a ICS stock rom for your galaxy
open odin 1.85 plug in phone select pda and add the downloaded rom (from fus) and then apply the update
this should fix your phone and restore it to ics
...
Did you try: Wipe data/factory reset and wipe cache ?
Try a wipe data/factory reset, if it still doesn't fix it, grab an official ICS version here and flash it with Odin.
Btw, be sure to read the instructions for flashing on that thread.
Thank you all... I manage to make him start again... I didn't try flashing the stock rom because I was afraid that I'll lose all my data.
Thank you all again.

Desperately need help with my S3 PLEASE

I am unable to get my phone to boot up. I was running resurrection remix fine with no problems, but decided to change ROMS. I did a full wipe and flashed Criskelo ROM through CWM, all looked well, but my phone wouldn't boot. I get the samsung sound and then my phone gets stuck on the Samsung screen. I restored my backup of resurrection remix, but again, my phone wouldn't fully boot. I then decided to flash the original firmware through Odin, which went well also, and passed. But again, my phone wont boot. I know i am using the correct firmware as i have used this firmware before. My phone will charge with no problems, but i cannot get past the Samsung screen. Can anyone help???

Roms will not flash.

I have a galaxy S2 I9100M with bell mobility with ICS 4.0.3. It is rooted and running siyah kernel 4.1.2. And for some reason it will not flash ANY Rom. I do the whole wipe process. install the rom. and the phone just gets stuck on the Samsung screen. Won't boot into recovery only download mode? so i have to re flash my stock firmware through odin. I have tried many roms, all with the same outcome? I had previously flashed paranoid 4.1.1 and CM9 9.0.0 before but now it will not let me boot either. Is anyone else having this problem or does anyone know what I'm doing wrong?

Sorry about that bro.
Visit this thread, for possible solution to your problem
Good luck
Something I do now after flashing a custom ROM is to "format /system" from the mount menu in recovery and also "fix permissions". Might be worth a try. Also, you could try removing folders on your SD card that contain data that are interfering with booting a custom ROM.

Sorry, I should clarify what I said above, as format /system is done prior to flashing. What I do is:
Wipe data/factory reset
Mounts and storage-> Format /system
Flash custom ROM
Wipe Cache
Advanced-> Wipe dalvik cache
Fix permissions
Reboot
Thank's for the responses. I have tried both options and neither work. I managed to flash cm9 through odin but the gapps won't flash threw cwm and the home button is unresponsive in the rom. Very frustrating.

[Q] [Strange] [HELP] problem with flashing my S II

I have a very strange problem with my Galaxy S II
I was on RR rom and then moved to leaked JB 4.1.2 and stayed on it for months,, A few days age I tried to install Thebyani stock rom which is just an deodexed rom of the official Spain LS8 firmware. when the device boot up after flashing the rom via recovery I had no Lockscreen at all!! and the device restart after long pressing power button and in other instances too.
I was so confused and went back to the leaked LSJ via odin and my problem was that the welcome screen doesn't show up!! I mean the first boot up options. I tried everything possible to reset the device completely and non of them could bring that welcome screen appear. I tried factory reset from recovery with wiping all kind of caches, then I reflashed the LSJ firmware with .pit file and re-partition option and still no welcome screen. I also tries Phzilla kernel to use its option of wiping everything before flashing a rom but nothing happened. The last thing I did was resetting the phone from settings with formatting SD and Internal storage and removing the sim, but of course none of it worked.
I wonder if any one suffered from this problem and what to do whit it!!.
Could you please help? Thanks in advanced.

Boot into stock recovery Volume up + Home+ Power then factory reset wipe cache and reboot do this after every flash as standard to stop bootloops.
i tryed everything is it possible that it is a hardware problem? should i keep trying?
As the above senior member mentioned.
You could try it.
You can also re-flash the latest stock OS. You can download it from sammobile or you can plug in your device in computer and update or re-flash the OS via KIES.
