POCO X3 Pro stuck in bootloop even after reparation of the fles

[matalena]

Hi,
Two days ago my Poco X3 Pro, as I was playing a game, froze and switched off. Since then it' has been in bootloop.
I searched in many forums and tried all sorts of solution pressing buttons, trying to boot in safe mode etc but nothing changed.
Today a local mobile reparation shop changed the flex cable of the power button but also this did not solve the problem. Still in bootloop.
Should I just give up and buy a new phone? Or has anyone here any other suggestion. All that is the forums here I have tried so no need to repeat the same suggestions...
Thanks in advance!

Can you give us more detail about what happened when you tried the safe mode? Because many things can cause bootloop

everything goes back to the Poco logo and bootloop! Safe mode too!

So it doesn't boot in safe mode? It may be due to power button getting stuck. You can give it a try if you haven't. Try lifting the motherboard

Cibillik thanks for your reply. As I said in the initial post, the repair guy opened the phone, changed the flex, he tried to get it to work and I trust he is good at his job. Still it did not work and he was at a loss. It's a shame to waste a good phone like this so I asked here to see if there was something else to do. I already bought a new Xiaomi redmi note 13, still what a shame...
Maybe I should somehow close this thread but don't know how to do that...
Thanks again!

I am sorry for what happened to your device. I hardly doubt that this bootloop is caused by a software issue. My device was bootlooping once because the power button was stuck or something. I didn't think this would be the case because it appeared out of nowhere and I didn't drop it or splashed water maybe it was the dust but I don't know. I tried to solve it thinking it was a software issue but when I tried to enter fastboot it rebooted again so I was sure that it was a hardware issue. I don't know the exact reason. I tried lifting the power button with a pry tool which increased the period of the bootloop so I thought if I disconnect it it would boot. I "fixed" it by putting a tape between the pins at the bottom of the power button. But before that I though it was the flex cable on the top but it turned out the be fingerprint sensor cable. I used my phone for weeks without using the buttons. It worked after removing the tape so I don't know exactly what fixed it. I think its worth giving another shot to fix the phone.
