After installing the latest update, the smartphone rebooted and black and white stripes appeared on the screen instead of the desktop. Rebooting didn't help. I can't restore the SOFTWARE using Xperia Companion because the smartphone can't be unlocked and the screen doesn't respond to touch.
Same story XA2 H4113 todays update around 950Mb. Boots after update, white screen for 3-5 mins, then black, screen itself acts like alive, i hear button clicks but screen is black.
Made full off (PWR+VOLdown) nothing helps
Tried to recover using sony companion software in recovery mode (when device can't be switched on) it downloads same update (...342 or something like that), on boot story repeats.
Emma software says im locked bootloader (tried to downgrade to oreo), i can't unlock bootloader since u must allow it from live phone....
Total stucked. Only chance they re-call back update in companion software so we can flash oreo with without service center/unlock bootloader etc.
I will not pass it to service, i better throw it in trash bin and flame XDA/4PDA/GSMARENA with tons of hate.
Please act quick Sony, or cancel biz if you your R&D can't test software prior launch. This is not allowed for brand name like you, only cheap china oems can afford such failfest with excuse of their low-cost products.
P.s. sorry im over hyped with anger
