If you phone doesn’t get any GPS signal then this is the solution:
- Install latest rooted TW (original Samsung Touch wiz rom) like (Alexandr ROM )
- Install from play store Shortcut Master (https://play.google.com/store/apps/d…cutmaster.lite)
- Open ‘Secret Code Explorer’ menu, scroll down to 27663368378 and launch it (select ‘Launch 0’, root is required).
- Then select the latest menue option Hardware sensors
- Then the latest option restore (rebuild) NVRAM (or something like that. I’m writing this from my memory )
- Reboot the phone
- Try GPS – it should work
- Now you can install new CM rom or restor version from TWRP or any other recowery
