Availability of broken phones in my area has been rather low, however aliexpress has cheap motherboards available, and I have already ordered one.
It would just be interesting to try to rescue the phone seeing how all data should be intact, just inaccessible.
This phone is near useless with the sony partitioning layout, I will attempt this again (after doing backup of trim), just so that it can run play updates normally without having to uninstall and reinstalling half the apps.
