I got a Zeki TB-782b off Amazon as a replacement for another Zeki TB-782b that had a cracked screen and was bought from K-Mart. The first one had a perfectly functional GPS and a good one at that. The current one does not seem to even have a gps I installed Google Play to both of them successfully using the same method for both. Google Play says the new one is listed as incompatible with a whole bunch of GPS apps, often the same apps the first one was compatible with. Opening the lid both appear to be structurally identical. Outside Both serial numbers start with 020 and end with AA Above the serial # both have FID:BN written on them. There are subtle differences. outside the old one has the FCc logo standing alone. The new one has a box to the right of it reading "C8OTB782B" This could be explained by parts sourced from more than one factory. Under "About Tablet" I think I may have found the problem. The old one: Kernel Version 3.0.8+ szg@server124 , Build number crane_dlyx-eng 4.0.3IML74k20120327 test-keys. I have read that this is the standard and confirmed other owners who have this version. The new one: Baseband Version 1.2 (not even listed in about tablet in old one), Kernel Version 3.0.8 szg@server #1 , Build number crane 4.0.3 IML74K 20120510 Both do have the file dev/gps_gpio but the built in document viewer can't do anything with that kind of file so I have no way of knowing if it is blank/corrupted. How do I fix the gps problem in the new tablet and is it even doable? I don't want to spend $70+ on fixing the screen on a $120 tablet if I don't have to. Ideally I can fix the gps on the new one and get Sears/Kmart to fix the screen on the old one for a good price.
