Moto 2nd gen XT1072 - ROM, Version and Camera problems

I've got a problem with Motorola Moto G 2014 LTE XT1072...
It looks like it is the MOTO G 2014 LTE version, from what I could read from the internet about XT1072. However, all ROMS for XT1072 are THEA, and my Motorola is TITAN. I don't understand why I've got TITAN -. everywhere I look, I see THEA XT1072 and TITAN for devices lower than 1072

Because of this thea/titan problem I flashed some ROMs dedicated for MOTO G 2014 version, hpwever:
1. Some ROMs are not compatible(can't even flash) because bootloader version 4882 is required. I've got 4821.
2. Older ROMs (Android 4.4 or 5.1) sometimes work fine, however on every single one of them the camera doesn't work. It did work on stock rom.

My questions:
1. Any ideas why my camera doesnt work?
2. How to update bootloader to 4882?
3. Is it possible to change my device from titan to thea?

Dead android with warning triangle on XT1072

Decided to OTA (not sure why) my Moto G LTE that was and was running stock but with an unlocked bootloader but have ran into issues and think i am now just digging a bigger hole for myself so I am asking for some help please.

I after the attempted update i started having issues with some apps not working and/or uninstalling themselves. Play store was the worst (tired wiping cache and data but no joy) then the camera decided it would uninstall and then any other camera apps in added wouldn't save pictures. Managed to get a fresh stock rom install.

So i though i'd update to CM13, downloaded the file, twrp and Gapps and set about booting into recovery to install twrp but initially i was unable to enter recovery and it stayed on the fastboot screen. Now i am getting the dead android and the red triangle but have a working stock rom.

I can now no longer use fastboot, all it does is start the rom as if i had just powered on normally.

Any help appreciated.
