I'm on eu dev 6.5.19 and I flashed stable 7.3.4.0 stable via TWRP, wipe dalvik/cache, rebooted and at the homescreen, some android process keeps popping out that is has stopped and I can't use the device. I think it had something to so with contacts/dialer because when I click the contacts app it keeps rebooting. Any work around on this? I want to flash stable 7.3.4.0. Thanks a lot!
