just an FYI since your stock ROM is gone.
You have SAVED MY WORLD!! HUURAAAAYYYYY!!!!!!
The OpTimized ROM was PERFECT in bringing back my GPS, it locked in seconds. It took me a few tries to get it active on Carbon4.3, so I'm going to give my "steps" for successful completion.
I FULL WIPED before flashing OpTimuS_V4.4 (ODEX) - that's Data, System, Dalvik and Cache. (Obvious? I first ran a full TWRP Backup of the system, data, boot)
Then I flashed, booted, and let it go through its process. It took its own "soft reboot" which I thought would turn "Bootloop" but it did NOT... rebooting to the "Semi Stock OpTimuS" perfectly. It did the "Activate" process on its own.
Then - I went to System Updates. PRL first, then Profile. Then the VITAL UPDATES were Google Maps and Play Services.
After this, I rebooted to let it reacquaint, and then installed FasterGPS, using it to clear the current aGPS. Next, installed FreeGee.
Opening the updated Google Maps, I IMMEDIATELY got the lock, but let it sit for 5 minutes. (reset "display time" to 5 minutes to keep track.)
Next - AFTER the GPS locking for 5 minutes, I did a backup of EFS with FreeGee. If you have PREVIOUS BACKUPS on the Internal Storage, they need to be replaced. This can be easily done with ES File Explorer, or any which allow root access. Go to the active (sdcard on LS970) FreeGee, copy the EFS settings, and replace those in the "/0" or Legacy FreeGee folder.
This may be "overkill" but I went back into Google Maps, got a Lock again, let it sit a few minutes and "tested" the navigation function.
While still in Maps, I powered down. Booting into Recovery (I use TWRP), I ran a RESTORE of my TWRP Backup, since the backups aren't "install" compatible. My fear was the "Restore" would override my updates, but when you run it, just "uncheck" EFS in the restore choices and you're
My LS970 booted up LOVELY, ran its normal boot process, and when I opened Google Maps .... ~*Aaaaaaaahhhhhh~* light from the Heavens! It locked FAST, and the Nav even worked!!
I have been trying to find this Fix for almost TWO MONTHS so I am on Cloud 9 right now!! Thank You @etownguy
