G7 Power with Magisk 21.3 won't power on. - Moto G7 Power Questions & Answers

In case anyone else has the same problem:
After installing Magisk v21.3, the phone wouldn't power on. The usual post-install reboot did nothing. Pressing the power button did nothing.
Fixed it by accessing bootloader (power + vol down), then
Code:
fastboot boot twrp-3.5.0_9-0-ocean.img
and flashed the previous version.

Magisk v21.4 is working OK.

Wouldn't power on? Then how did you get it into fastboot mode?

It wouldn't power on using just the power button. I was able to get into fastboot mode using power + volume down.

Have you tried to fastboot a recovery image?
Code:
fastboot boot recovery.img
Where recovery.img is the full path to your correct recovery image on your computer
ie:
Code:
fastboot boot C:\recovery-RA-sapphire-1.5.2.img
i tried doing that but it said
FAILED <data transfer rate failure <too many links>>
**nvm, it worked now**
hm i'm still relatively new to Android, but don't you enter recovery mode through home + power and not menu + power?
wow, I could of sworn I used to be pressing menu + power..Guess I haven't flashed a new rom in a while.
I thought it was Back + Power!?
back + power (and volume down + power) gets you to a boot screen/status screen where you can check motherboard and radio.
home + power is how I've always gotten to the recovery screen

Battery discharge solved this problem. After that my S860 boot normally.

TWRP won't boot from device, only from PC.

I bought a cheap G8141 on ebay with a cracked screen and replaced the screen myself.
I unlocked its bootloader.
Then I attempted to flash twrp into its recovery with
Code:
fastboot flash recovery twrp-3.2.3-0-maple.img
using the latest twrp maple image.
It says it succeeded, but I can't actually get it to boot into TWRP using
Code:
fastboot reboot recovery
or
Code:
adb reboot recovery
or by using any of the button press combinations (hold volume up or down + power, or power on and repeatedly press volume up or volume down).
I can only boot to twrp using
Code:
fastboot boot twrp-3.2.3-0-maple.img
instead.
I did root with magisk, and I also attempted to flash twrp to recovery from within twrp after booting directly like above, but it still won't work.
make sure your device is OFF and is NOT connected to a charger.
Then, while holding VOL-, press and hold PWR, and wait till you see TWRP.
Mine wouldn't boot into TWRP if it's on a charger, or if i'm rebooting. Only from the Device Off state.
I thought I tried it without the cable in, but i tried it again and it worked.

I think I just bricked my phone, Please help

Don't know what I did in TWRP recoverty, now I can't boot into to fastboot or recovery. Black screen with `MI` logo stuck there.
I did tried connecting with PC, adb showing
Code:
no device found
.
What can I do?
Try to enter twrp by pressing Volume up + Power button or fastboot mode - Volume down + Power button. Or let the phone discharge completely and then try the above key combinations.

[Bricked?] Stuck on Unlocked bootloader screen

Uninstalled magisk to update OTA to 6.8 (because it wouldnt work) then it just reboots and now its stuck here on the "blah blah your bootloader is unlocked"
OS: 11.0.6.7.kb05aa
wtf can i do, pc doesn't detect it?
Try the below hardware key combination to get into fastboot and flash your stock boot.img (from the correct rom) and see if that fixes it.
If not you can try to flash the latest rom through fastboot.
If that is not working you can always use the MSM/Unbrick tools (see posts in Guide forum) to restore completly to stock (Warning this will wipe your phone !)
To enter Fastboot and Recovery Modes using the physical button combination, you will first need to power off your OnePlus 8T completely. To do this, simply press and hold the Power button to bring up the Power menu and select ‘Power Off’.
Once you have done that:
Press and hold the ‘Volume Up’, ‘Volume Down’, and ‘Power’ keys together to enter Fastboot Mode
Press and hold the ‘Volume Down’ and ‘Power’ keys together to enter Recovery Mode
