I’ve posted a little lately about playing around with Android. One of the things I had done was installed CyanogenMod on my Samsung Galaxy Tab (P1000) for my wife. She was having problems with it, so I tried to update it to KitKat. The upgrade went fine, but I couldn’t get the Google Play store to work, so I decided I’d just revert back to the original Gingerbread that was on it when we bought it. However, the backup I had done originally didn’t work.
I ended up following the instructions on a web site that isn’t live anymore. However, thankfully Google Cache had a copy of it. I also followed the instructions at http://www.youtube.com/watch?v=nk_TNy-h2Bs and it is back to the way it was.
Note: Depending on the tablet you have, you may need a proper modem file which you can get at http://forum.xda-developers.com/showthread.php?t=1069727
