Ok, here it goes. A few weeks ago I bought a used galaxy s II in perfect condition. It had the latest resurrection remix rom when I bought it. All good, right? Well today a new update for the rom came out. I downloaded it, installed it and it started messing up my phone. The play store wouldn't work anymore, google play music wouldn't work anymore, etc. Reinstalled it, fixed some of the problems, but the store disappeared. Factory reset it, the store was still not there. Started searching on the net how to bring it back to its original firmware ( I am a total noob with roms and all ) and read somewhere to go into the volume up, menu, power combination menu and wipe it all out. Now the phone won't start anymore. It's stuck at the dorinmanx splash screen. Also it starts itself on no matter what (unless it's connected to a computer ).

I am really desperate. I only wanted to bring it back to where it was when originally bought. Now I feel like I've messed it up completely. Please, help me!

P.S - maybe I can put a stock/custom rom on the micro SD and install it?

PLEASE HELP ME!

THANKS IN ADVANCE!

 

I did manage to get into the download mode at some point, BUT it just got stuck on the DOWNLOADING, don't turn the device off screen and that's it. It won't advance further. Also, I am really not sure if USB debugging is enabled.

 

Fixed it. Thanks for the links geoffibs. Now I have the unofficial Samsung JB... AND I finally have the FM Radio back... YAY!

 

OK, another problem appeared. I did install the Samsung JB update, as suggested by geoffibs, BUT now the phone asks for the SIM unlock key and I don't know where the efs folder/partition is, so that I can access the bin file and generate a key via the Samsung Unlocker.

Everything else is working fine, but I really need this file, so that I can generate the key and start using the phone, you know... as a phone

Thanks in advance!
