There are several places to get the ota update files for .901, but to flash it from stock recovery you must be completely stock with no frozen or deleted system apps and an unedited build.prop. I don't know about the your overclock situation, but I think it could be a problem, too. I had a copy named build.prop.bak because I edited it with Root Explorer which made an automatic backup. Don't know about your rom toolbox editing the file, but you could look for a backup. If you have to use P3's method to go back and try again, stop after the .893 update and get root and forever root. Then you'll keep root when updating to .901 by flashing it in stock recovery.
