Unfortunately this process didn't work for me. The various market fixing apps on the market don't work either (it's hard enough just trying to find their .apks since I can't download them over the market) and my CleanRom lost its keyboard and launch buttons thanks to trying this method. Looks like I'll have to wipe the device tonight. *sigh*
Some days ago I flashed a ICS Rom, all went good but the only thing that i noticed was that my phone name had changed to lt18i in the market. Today I decided to go back to my previous GB Rom so I restored it from my nandroid backup. Now my phone is still identified as a lt18i and cannot download anything from the market. I tried to wipe the app data of the play store app but didn't do anything. Also the remote download from the pc doesn't work at all.
What other things I could try? I really want to avoid a factory reset if possible.
EDIT: Found a solution, i moved/deleted the /data/system/accounts.db, wiped the app data from the Play Store and restarted the phone, added my google account again and the market updated my device name and the downloads are working again.
