I resurrected my screen damaged OPO using a display bought off aliexpress.
I am observing a problem after that. Not sure what caused it
1) When the phone is off, if I plug in the charger, the screen does not turn on and the battery charging icon is not shown. Even the LED is off
2) When the USB cable is connected to a computer, I am unable to enter recovery mode or fastboot mode using adb. If I give the command adb reboot recovery for example, the screen goes off and stays off. If I remove the cable and then long press the power button for 30 seconds, the phone boots up. If cable is connected, no matter how long I press the power button or any combinationof buttons, the screen stays off
3) Same observation with wall charger connected. Using Advanced reboot options, if I reboot to recovery/boot loader, the screen goes off and does not turn back on
oem device info shows below.
The device is an international version not a chinese one.
./fastboot oem device-info
(bootloader) Device tampered: true
(bootloader) Device unlocked: true
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
(bootloader) console_enabled: 0
(bootloader) exec_console_unconsole: 0
Any help is appreciated. Thanks

Can someone please tell me what to do in order to connect my surround to my computer in bootloader mode? Is there an app I have to download?
Disconnect the phone from the USB plug (but make sure its battery is charged!) and turn it off. Press and hold the Volume Down button, then press Power while still holding it. You'll get a screen with bands of color and yellow text; this is the SPL (bootloader) screen.
Yes, I know, I need to know how to find the drivers but I think I got it thanks.
The phone is switched off due to a fall impact which caused slight movement to the battery interrupting the power. Is there any way to boot without those important keys? It's stuck on the battery charging screen when I plug in the cable and I can't think of any other way to bypass that to access recovery or download mode because if I do, I can boot the phone from either of those two using adb or fastboot commands. I can't do anything on the battery charging screen. Is there a reset pinhole or something in this phone? Is this a dead end?
Should be able to short the power switch pins, I replaced the switch in my nexus 5 ages ago and couldn't tell you which pins did what, but it's 100% possible with a small length of wire/paperclip.
Run fastboot oem off-mode-charge 0 on the bootloader the next time you can and you'll be able to turn on your nexus just by plugging it in into a computer or charger. Quite useful when your power button doesn't work.
And yes, shorting the power button is the only way you're going to turn it on, careful though.
To access the bootloader without volume down you can use adb reboot bootloader

Hello there!
I tried to replace the battery of my phone with another one, but the phone doesn't boot up at all.
Shortly after I switched the battery, I managed to boot the phone: the HUAWEI writing showed up and then the phone shut down.
The red led was blinking while charging and other tentatives of boot-up failed with only a vibration shot and nothing more, with the screen still black.
Just out of curiosity, I tried to go to fastboot mode (by holding DOWN volume and plugging the USB cable on pc) and surprisingly enough the "plug in" Windows sound played but the phone remained pitch black.
The curious thing is that if I type
Code:
fastboot devices
It shows a number and the writing "fastboot" so I guess that the phone is recognized by the pc.
Is it bricked or something?
Or maybe the battery was faulty and ruined the motherboard?
Or maybe it is just the screen broken...
I don't really know how to proceed.
I have had my OPO for about 4 years and am currently running Lineage 18.1 with no issues. However the Power button on the phone stopped working and will not do anything. I inadvertently put it in Fastboot and cannot get out of Fastboot and reboot to normal. I have tried adb to see if I could do a reboot there but it is not detecting any devices. Before this incident the phone was unlocked, in developer mode with usb debugging set. Is there some other sequence to try. I have tried vol down and plug in usb, and vol up and plug in usb, and held vol up and down and plug in usb but none have worked. Any suggestions please.
Update: I just got Fastboot on the PC to reboot the phone. Yea. The Power button is shot. It has been in a case for years and I hardly ever use the Power button anymore. Don't know why it has failed, no abuse, maybe lack of use. Thanks anyway.
If I take the button out, does anyone know if the inner switch could be pressed with something to turn it on and off. I assume there would be somethin like that although I have not been inside one of these before. If I ever lose power on the phone I will not be able to turn it back on without the power button/switch.
I completely drained a OnePlus 6 (6 gb) running Lineage OS 18.1 with Magisk root. When I plugged it into the OnePlus charger that came in the box, it started to boot loop, showing the 1+ logo, the unlocked bootloader warning, then "Battery is too low" warning (red text, different languages), then shutting off to repeat that. Sometimes it would not do the "Battery is too low" warning.
I've left it to charge for 2 hours now with no luck. After a while it stops boot looping then just stays black. When I click the power button once it shows a charging screen, a circle with a lightning symbol and shows a charge going into the circle.
It does not boot when not plugged in.
When I try to boot it and it goes onto the 1+ logo screen or any screen, then I unplug it, the screen will completely turn off.
I've tried to access fastboot mode and change chargers but both don't work. Holding the volume button and power button just starts the boot loop from a black screen.
Is there anything I can do to fix this problem? Or another forum that might have a solution? Thank you.
Edit:
I am able to get it into fastboot mode, but I cannot boot into twrp through "fastboot boot" or from the recovery mode option.
When I use "fastboot getvar battery-voltage" I get either 4329 or 1802.
