Reinstall on Proscan PLT7650G Tablet? My son has a Proscan PLT7650G tablet that will not get past the ProScan startup logo.  I have tried a factory reset and its still a no go.  Before I throw in the towel I want to try an OS reinstall but I am not sure how to go about it.  I am a programmer/dba/sys admin and I am not afraid to take it on but my knowledge of Android is very limited.
Try this:


Download the firmware from this site
Extract downloaded .zip (Should contain a .img file)
Rename .img file to update.img (If it isn't already)
Copy update.img onto SD card (Should be the only thing on the card)
Reboot. Should install the file.
