Stuck in Bootloop - OnePlus 7T Questions & Answers

I installed magisk module to give my phone some Pixel features, and now the phone is in bootloop. I can't even turn it off to boot fastboot and try to remove the module?
Help!

Press vol- and power button to boot into Bootloader and follow this tutorial.
https://forum.xda-developers.com/oneplus-7t/how-to/magisk-twrp-root-module-uninstall-t4002843

I got it to boot into fastboot after the battery died, then I fired up twrp and did a factory reset. Used to be able to uninstall a module that was causing problems, but not anymore.

plug it in to charge for a few hours, then use adb to reboot into bootlaoder or recovery. Flash away from there.
Code:
adb reboot recovery

Hi sorry I can't remember when adb kicks in, maybe the fastboot commands become available earlier.

Bootloop problem

Hello,
I have a problem; I recently tried to root my device running on Android 6.0 sense 7. I unlocked the bootloader and installed Twrp recovery and then flashed SuperSU zip, after that I wiped the cache and rebooted, but now it's stuck in a boot loop, I can't do anything, also I can't adb into the device. It is stuck on the HTC logo with powered by android below it. My pc recognizes the device I think because it makes the sound but when I try 'adb devices' it says list of devices attached and nothing. also fastboot can't seem to find the device. What do I do?
Have you tried restoring a backup or flashing a custom rom?

Hold volume up and power button to restart phone from any hang keep holding the buttons for 5 seconds. Or use volume down + power button and same hold for 5 seconds to go to fastboot

I also had the same issue but what I did is, I let my device to drain the battery, and then I press the Volume Down + Power and plugin the charger and it gets me to Bootloader ^_^ I don't know what your bootloader combination is but just press them before putting the charger. And oh, DO NOT REMOVE THE CHARGER UNTIL YOU ARE FINISHED FLASHING THE boot.img of your ROM.
it's fixed, flashed stock rom and recovery. Thanks guys
I also have the same problem. Can you provide a link to stock rom and recovery PLEASE. Thanks!!

Stuck :( TWRP flashing screen

So I was trying to install TWRP on my phone. I have a Mac and was looking at some online guide. I had a pin set-up, and this is what I did:
1. Installed ADB and fast boot
2. Unlocked the boot loader on the phone
3. Check the terminal commands that the device is connected correctly
4. Had the ABD and TWRP img files on the phone.
5. Tried to fast boot TWRP.
What is happening now is that I'm stuck on a boot loop of a TWRP screen, the screen if flashing and won't load. I'm guessing to let the battery die out over night
I was looking at a few threads and some say that I should flash the factory image. Everyone is saying flash the stock file... However, I can't even get the phone to turn off or go back into bootload mode for my computer to recognize the phone.
Any tips?
Hold volume down and the power button down. Keep it held down might take sometime but you should get to the loader. boot twrpRC1 flash rc2 after getting in twrp. You could also start fresh by fishing factory once you get back to bootloader
Long press power button to shut it off
or press power button and vol down together and will take you to fatsboot mode and from there you can use volume button to seltect bootloader or recovery
I don't do pin's so I'm not familiar with the hangups involved with those and TWRP.
But I guess the first thing I'd do is remove the pin lock.
Then power down phone.
Wait 30 seconds!!!!!
Press power + volume down until phone powers on, then let go.
Should boot right into bootloader.
Fastboot boot twrp.
Install TWRP from the fastbooted TWRP.
I'm not familiar with the Mac process but on a PC we need to fastboot into TWRP from an image file on our computer first, and then flash the file on the phone.
I recommend keeping a copy of the boot signer on your device, flashing this fixes most of these types of issues I have found, especially with new rom upgrades etc.
Did you let the phone fully boot into the system after unlocking the bootloader, or did you immediately try and boot twrp?
I've had this problem twice before, both after a fastboot unlock, and I had to let it fully boot into the system before proceeding

Thank you you too. That was the problem, my patience. I didn't hold it down long enough for it to boot back into boot loader mode.

Hey I think that was it. I immediately tried to boot twrp without letting the system fully boot.
Thanks you all for the support. Go XDA!
The first question everyone should be asking is if OP was on the O Beta previously.. If that is the case Op needs to flash the factory image in both slots.
Put phone into the bootloader
Flash all bat
Put phone into the bootloader
fastboot --set-active=other
fastboot reboot bootloader
flash all bat
fastboot boot twrp
Even if OP wasnt on the O beta, this should fix the issue.
After successfully flashing Oreo, I am seeing the same flashing/looping TWRP (twrp-3.0.2-0-RC1).
Long press of Pwr restarted the phone.
Rinsed & repeat a few times.
Any thoughts to flash TWRP (temporarily)?

Stuck in Bootloop, reboots every 15 seconds, holding power button does not stop it

The first problem I encountered while rooting my phone was that TWRP wouldn't stick, even though I didn't choose read only (ie i allowed it to make system modifications on the first TWRP boot) after rebooting
and booting back into recovery I would boot into stock recovery, instead of TWRP. So I tried flashing twrp, booting into it and rooting the phone, which was successful!
THE ROOT was successful, TWRP still didn't stick, every time I want to boot into TWRP I have to boot into it via fastboot.
Getting to the main problem, I booted into twrp, flashed a custom rom and got stuck in a bootloop while rebooting. It reboots every 15 seconds, I have kept the power button pressed for almost 2 minutes it doesn't stop the bootloop, I tried other combinations of vol buttons and power buttons does nothing.
One weird thing is that while it's in the loop I just have to press the vol down button and it boots into fastboot (as opposed to both the power button and vol down) when I boot into fastboot it stays there for about 6-7 seconds before rebooting, I tried booting into twrp through fastboot, but before I am able to enter the decryption password to start twrp, the phone reboots.
Should I let it run out of battery? will that stop the bootloop? I have a backup in twrp but I can't access twrp!
Does anyone have a solution?
[update] I let it run out of battery and on charging it continued the bootloop, with great difficulty i managed to install stock img file but the device just wont quit the bootloop

1. Try flashing new recovery image using TWRP booted via fastboot.
2. Does your phone had contact with any fluid or was in place with high humidity level for longer time? Your power button is short circuited. In other words it is in pressed state all the time. I had same problem on my previous P2 when I came from 1h running session in light rain. Some sweat and/or water got inside my volume down button and same thing happened.
In my case the phone button recovered itself after drying and clicking it a lot of times

I can't access TWRP as the phone doesn't give me enough time to enter the password for decryption, which is asked at the start every time you boot into TWRP, I get like 5 seconds in TWRP before the phone reboots
It is possible that the power button is spoilt as I have sweaty hands...

That's the reason. I know that pain. You should try pressing that button with different pressure (but be careful) and move you finger while doing it. Maybe it will recover itself. If not you should find someone trusted who will open the phone and clean the buttons from the inside. It's a shame that Lenovo just left this construction vunerable like that.
After you get your P2 working properly again then just buy case that will cover whole buttons to prevent situations like this next time. Also make sure to clean it regullary inside.

Help - Soft bricked brand new Z2 Force (XT1789-06)

Hi guys,
I just recently bought a Z2 Force EU model (XT1789-06) and thought i better get it unlocked and rooted a.s.a.p.
The first order of work was to boot it up and perform an update to the latest updates available (November 2018, IIRC).
Following the update and after making sure there weren't any more updates, i proceeded to unlock the bootloader using the official Motorola method and it was successful.
I then copied over SuperSU-v2.82.zip to storage and downloaded twrp-3.2.3-2-nash.img to my PC.
I followed this guide in order to run TWRP and root: https://forum.xda-developers.com/z2-force/how-to/oreo-nougat-how-to-root-z2-t3756669
After installing SuperSU and rebooting the phone, the Motorola logo was displayed and stayed there for a while. I remembered the verbose logs after installing SuperSU syaing that first boot could take a long time.
I didn't risk rushing anything so i left the phone and planned on picking up where i left off the next day. It has now been 14 hours since the phone rebooted and it is still stuck at the Motorola logo.
I have tried to power it down by holding the power key but that does not work. I could only force it to react by holding down vol down + pwr button, then doing the same again to enter the bootloader.
I then tried to do a factory reset by performing the following:
vol down + pwr button > select recovery mode > hold pwr 2 seconds then vol up > Wipe data/factory reset > reboot
I am now back to a stuck boot procedure at the Motorola logo I did some more reading and found many threads explaining the procedure and what to look out for.
It seems like my safest bet now is to avoid SuperSU and install Magisk instead. However, before I attempt to root again, I would like to have the phone boot up normally again.
Would a kind sould please point me in the right direction of a guide that can help me out of this mess?
Please note, I am already using the latest software update version.
EDIT: Software is 8.0.0/OPXS27.109-34-17
fastboot --set-active=other
fastboot reboot
Take the update again then flash magisk after rebooting from the update.
What happens? You are swapping slots back to a working bootable slot, then updating to the latest update to fix the broken slot. Once it is fixed, follow the rooting procedure and flash magisk 16.7 or higher in TWRP and reboot. (Be sure to fastboot boot TWRP and not flash)
