Hi,
I experienced black rear camera bug on Official LOS16 (I have to admit that i had made backup and tested carbon and LOS17) Now i installed 17 to test if is it ROM problem but i think it is unfortunatelly hardware problem. I saw other threads and searched internet and decided to install stock branded marshmallow, lock bootloader (Yes, I had backup TA before UB) and send it to official Sony service because I should still have warranty.
But...
I don't know how to install stock ROM. I downloaded branded software from XperiFirm and stopped there. How to flash it and not brick device? Newflasher is for newer models. Flashtool needs .ftf file. I searched how to convert XperiFirm package to .ftf on other model but there is step where you have to decrypt some files (I couldn't find them in downloaded software package).
I thought about second option - format and wipe in twrp all internal partitions and use Xperia Companion Software Repair. Actually I don't know does it work properly with UB devices...
I decided to go to the unofficial Sony devices service if it'd be problem with sending it to official Sony service.
What do you suggest? Is it easy and cheap enough repair for unofficial service not to damage device? I have no tools in home neither any preferences or experiences to do that by myself. Should I skip installing stock and go straight to the unofficial service?
If you suggest relocking device please help me and write step by step, noob friendly instruction how to flash XperiFirm package by flashtool or post made that way tutorial.
If you can help me, thank you!
