Have you tried reverting to factory recovery, if you are not rooted. If rooted you may need to unroot first and do a factory recovery but ensure you back up your personal data and APN settings to your pc first.

I have the same "issue" with mine. I have flashed via ODIN back to stock and still zeros. This might cause my other problem, no sim connection but I have not found a solution yet. Hopefully we can figure this out.

If you had a copy of your efs folder, use it to replace the current efs folder. That may help. On the other hand, if you can get a tab of the same specs, copy the efs folder there and use it to replace yours. The drawback may be that the two tabs will have the same IMEI number, which you can then change to your original number. There should be an app to change the IMEI number.

Hope this helps.
