So I did a factory reset yesterday. Before hand I backed everything up in Appbrain. I also used Astro and backed everything up that way onto my SD card. I then put all of that onto my PC.
Everything went fine except for 1 app.
I went to appbrain and tried to get it, and it told me it was not there.
I went to the market and I could not find it.
I went to the backup dir from Astro and there was no APK for it.
I also checked my PC for the APK and it was not there either.
Am I just SOL now? Is there any way for me to get it back?
Log into the desktop version of the market and look for your download history. If it's not there then you are probably at a loss and can't retrieve it. Either the app was removed from the market or is no longer compatible with your device (which I don't think is the case).
