I just got my new ZTE Awe changing carriers to Virgin from ATT (overpriced, wow.) I'm new to rooting of course (why else would my phone be bricked). I liked the phone a lot but hated the virgin bootup sound (so noisy and awful). So I deleted that file, I think it was called Bootsound_virgin.ogg in the system/etc folder. To do this I had to change permissions to write: (chmod 777). But then... When I finished, I thought "gee I should change permissions back." As a linux-like newbie I changed it to 444. I think doing this wrecked my phone's needed permissions, because now my phone won't boot. How do I get back in there and reset that permission? I can boot the phone in FTM mode but I'm not sure what to do from here. Thanks so much. Will update as I progress. update #1: I can boot into "android system recovery <3e>" also. update #2: I tried a factory reset, no luck. md5 check reveals: ---begin md5 check--- -system/etc/Bootsound_virgin.ogg <long hash> +system/xbin/su 100452 <long hash identical to next hash> +system/xbin/su 100452 <long hash identical to last hash> Diff sum:3 System files are different with the official ---end--- Update #3: I tried wipe data/factory reset but phone still won't boot. The Virgin Mobile animation will play, but then the phone will hang on "ZTE" Update #4: I learned how to use android SDK with adb shell in order to get a shell command on the phone.
