My Z Ultra (C6833) was running stock Lollipop, with stock locked boot loader. I.e. the phone was completely stock.
I somehow managed to crack the bottom corner of the screen, which rendered the digitiser useless. I replaced the LCD/digitiser assembly, and have had nothing but problems since. First of all, since installing the new LCD/digitiser, the battery was idling at ~60 degrees, which was killing battery life and made the phone unusable. At this point, I unlocked the bootloader and flashed CyanogenMod CM11. CM11 solved the battery issue straight away (normal idling temperatures and excellent battery life). However, at this point neither of the cameras worked (black screen on opening any camera-using app). The app's controls were functional, but the app would eventually freeze with one of the well-known 'camera not available' etc. errors.
I figured that I may have accidentally left one of the camera's PCB connectors unattached, so reopened the phone to confirm. I downloaded a system profiler app, which clearly showed that both cameras are connected. Given the known camera-related issues with CM11, I figured I'd try another custom ROM. I flashed Resurrection Remix 5.5.9 this morning, which again worked beautifully, but the issues with the camera remained.
My last attempt was to flash stock 5.0.x Sony Android back onto the phone, and then re-lock the bootloader. Again, this whole process worked as planned, but the cameras are still non-functional. Given that the system profiler sees/lists in detail each of the cameras, I'm on the belief that the flex cables/PCB connectors are intact, as the camera modules themselves are communicating with the motherboard.
This is my first foray into custom ROMs and flashing, so please excuse my ignorance. Are there separate drivers for each of the modules, like you'd expect on a computer, or are the drivers combined with the ROM? I.e. could the camera module drivers have been corrupted in some way? All the evidence suggests that there's a software/firmware issue here, not a hardware one.
Given that camera-related issues are common for this phone and custom ROMs, I've been through just about every forum post/video/HOW-TO guide on the matter, so I'm afraid the solution won't be as simple as "clear the camera app's cache and restart the phone in safe mode" ;)
Any input would be great!
Thanks :)
