Question device is not working after entering fast boot and exiting it

[1_coems]

mine phone is NOT working after entering the fastboot and exiting it so it ONLY works after the battery fully discharges. So can anybody help me so a don't have to go through this again?

I won't be able to help, but someone else probably could if you tell us what device you have, and what Android version it's running.

Different devices have different ways of doing some of these things. Staying vague about it doesn't help.

It's also not entirely clear what's happening. Are you saying that after entering fastboot at one point and then exiting, the phone won't boot up normally until the power runs out? Or are you saying the phone wil only boot into the fastboot screen, and you can't get anywhere from there?

To the joeldf (its a samsung s24 chinese copy bought from aliexpress it runs on android 8)
to diddy (the first things you said was what i had when it exits out it doesnt respond to anything just like it was bricked but if battery will discharge fully it will work after charging)

Since it's a Chinese fake/knockoff, all bets are off. Those devices have zero quality control (both for hardware and software), are full of lies when it comes to specs, and have no support whatsoever. Unfortunately, I doubt we'll be able to help with that. If it works reasonably well without trying to get into Fastboot, then just avoid Fastboot. But even then, you're taking some risks, especially if you want to use it for anything sensitive (like banking). There's a fairly high chance that these knockoffs have malware/spyware that's sending data back to unsavory servers somewhere for who knows what purpose.

try this combination of keys: hold power+vol up buttons for 15 sec then, When it shuts down, hold power+volume up again for a few seconds
