[AT&T Samsung Galaxy S II SGH-I777] macr1408:
Hi, i bought an used galaxy s2 i777. It is stuck at Samsung logo, also for any unknown reason it doesn't charge the battery, if i try to enter in any charge mode (plug the phone to the charger for example) a gray battery icon appears with a circle in the middle (not moving) and stucks there forever.

Recovery doesn't work

Only download mode works

Stock binaries, nothing custom, i even think the phone is not even rooted

Tried flashing 3 different stock roms with odin, all of them fails at the beginning "Nand write start!" and then fail, it doesn't even start to write in the memory

Tried with heimdall, any partition that i want to flash stucks at 100%, and then after a long time, if i am lucky, i get a fail error, otherwise i have to unplug the phone

tried flashing Siyah kernel (idk for what, but just trying), still fails (upload 100% forever)

tried flashing a bootloader, still stuck at 100 (with heimdall) and then fails

tried with a .pit on Odin and it stucks on "Set pit file... DO NOT TURN OFF TARGET" forever, only tried with one pit found on a strange website, links here (dev-host) are dead

Here is what i got from Heimdall using "print-pit"

Do you think this can be solved? or is my phone totally dead? I would really appreciate your help

EDIT: right after posting this, i tried with a different pit file, which obviously failed and then my phone doesn't turn on, i guess that now is totally dead :(
