A05 - ONE UI 7 - BLACK SCREEN

[xlrdrgz]

Has anyone here experienced a bug regarding the official one ui 7 update for A05 causing a black screen?

Was excited to have finally received the update so i hurriedly installed it. To be very cautious, I even left it plugged in so there would be no interruptions during the process. The installation was smooth and it rebooted properly. I even saw the one ui logo loading bar where it would show "optimizing apps".

But when it was done, nothing. Display won't turn on, was able to turn on Talkback able to hear something. At first, i thought it was just the display so i carefully disassembled the device and reseated the cable, nothing. Bought a new display and installed it properly, nothing.

My biggest mistake was that i didn't considered first that this was a software issue before buying a display replacement. Never thought about it because why would an official samsung update would cause such issue.

So what i did was reflash the one ui 6 firmware using ODIN, managed to put it on download mode without having a display confirmation and guess what... THE DISPLAY WAS ACTUALLY WORKING. To confirm if this was really the case. i tried reflashing the one ui 7 firmware on it and the display won't show anything again. Plugging in, i can only hear the charging sound but no display. Just reverted back to one ui 6 for the meantime.

Hoping someone has the same case as mine that's been solved because i really want that one ui 7 update.

teardown your phone then try plug and unplug the display port. I had this problem with other Android phone, and i was able to fix it by this method

How you do it mate?

use ODIN, you can lookup tutorials on youtube on how to use it, if you manage to trigger download mode. for firmware, i used samfw.com, it has a neat feature where it can detect the suitable firmware for your device if you allowed permissions on your browser.
