i'm using twrp, and i had tried to install cyanfox, and a slimrom, both failed in the installation, saying 'could not read zip file' or something along those lines. so a few times i recovered using a backup i had made of my aokp rom.
the installation directions i was following indicated that i should be formatting a lot of things, including the system partition, so the next time i rebooted into twrp, i pressed 'wipe', and then pressed the format button on the right (can't remember the label) rather than just swiping, which i believe formats the main partition. i thought this was what i was supposed to do...
now i can't reboot into recovery or download mode. all i get is the galaxy s iii and aokp logo screen.
which unbrick method do i need to use?
is it that easy to mess up my phone beyond repair?
