Is there another way I can flash back a stock ROM and unbrick my phone? Thanks in advance for the help, I hope you can help me out, I'm a total noob, it's the first time I tried to flash a custom ROM
EDIT: BTW, I hard reset the phone several times in attempt to turn it off and boot in flash mode, since the phone will not shut down.
2nd EDIT: I can't get into recovery either.
3rd EDIT: SOLVED using the x86 version of flashtool instead of the x64.
