I bricked it trying to get back to 893 from 901 and have spent 2 days trying to fix it. I did manage to get it back using rsd lite and the flashme file but when i did the OTA update it is bricked again and will only on to the battery ok screen says fastboot invalid at top and such. I have tried so many files to fix it now but everything i try to run says it is for the 32 bit system and I am a 64 bit syatem. I dont know how to write the command promp screen correctly to try it my self. I am on a vista OS and if that is what I need to do can someone tell me exactly what to write. i have tried dropping the fix files into it but it says it cant run it due to the 32 bit operating system proble.
