In Topic: XZ2 Locked Bootloader DRM Fix

18 February 2019 - 02:11

I don't know if it's because of drm or because of faulty hardware. I know for sure that it's impossible to unlock bootloader in phones with "Bootloader unlock allowed: no" and then relock it so most likely some prototype tester in Sony factory was playing with that phone. Anyway, enjoy it like it is =)

In Topic: XZ2 Locked Bootloader DRM Fix

I recently had the luck to get 2 XZ2 prototype phones.


Congratulations :)



Both phones had a user debug firmware with issues(notifications which you couldn't disable, lag, proximity sensor, camera).


That's typical for prototypes which are under development.



I managed to flash them both with latest firmware.


In my opinion terrible mistake. Usually prototypes works with prototype firmware. Also flashing retail firmware makes them unique no more.



The other XZ2 was T-telecom branded sim-unlocked but with bootloader unlock allowed no. This one works fine except from camera and x-reality features.
Although Bootloader is locked is like someone unlocked and relocked it so drm keys were lost.


Only Sony factory can do that.



I tried to unlock the bootloader so I can try a drm fix but it doesn't let me.


You have prototype phones stolen from Sony factory. Do you really think, that connecting them to Sony software is a smart decision?



I wanted to ask, is there anyway to fix the drm with locked bootloader?


In Sony factory, and only there. Sony service centres does not have required access level to do that. Also don't forget that you have stolen phones so i would not show them to Sony workers :)


Btw. you've lost unique prototype firmware, at least you have cool 0044 imei ;) And don't misunderstand me, i don't blame you for flashing retail firmware - your phone your decission. Just in my humble opinion if you have something unique like prototype Sony phone where there is maybe a few units around the world (because all prototypes are being destroyed), it's very valuable for collectors. By flashing retail firmware you are making not even a noromal phone, because prototype is always a prototype - not everything may work properly like in retail phone so it will be loosing on value even faster. But that's just my opinion ;)
