First, I wanted to flash Cm11 (by TheWhisp), but something went wrong during flashing process, and my device bootlooped.
I tried to go into recovery, but it didn't work.
Than I thought it might be a good idea to flash stock ROM via odin. I did it once in the past, with a succesful outcomes, so I fought it will work again.
This ended with a bootloop, only change was the logo during boot process. Than I tried to flash recovery but it didn't change anything.
So my phone is in bootloop, stock ROM flashing doesn't help, and I can't run recovery.
Any ideas how can I fix it?
