Phone currently stuck in fast boot screen, any help? - OnePlus 7 Pro Questions & Answers

Hi guys,
I need a bit of help in regards to my oneplus 7 pro 5g edition (GM1920) I previously attempted to root the phone as always and have accidentally wiped the system via twrp, i am now currently stuck in fastboot mode and it appears that the phone has now wiped the factory recovery as every time i attempt to go into it via the fastboot screen or reflash twrp, it shows the 1+ logo for a split second and reboots to fastboot, usually with previous devices reflashing twrp would have been enough but it seems that there is nothing i can do at the moment, any help or advice would be much appreciated.
Thank you
SOLVED: Turns out it was rather simple, the phone wasn't flashing to the correct partition and wouldn't let me change, but randomly after a few tries it finally let me change to the correct partition and everything now works like a charm again.

So if you are flashing TWRP through fastboot, it does the same and reboots to fastboot? Are you able to flash twrp successfully? If yes try power+volume down to go into twrp. Then change the slot

in fastboot use your vol buttons and scroll to RECOVERY and click power button after you flash TWRP

Hi guys,
Thank you for the suggestions but i manged to finally figure it out after hours of racking my brain, turns out it was a very simple solution, for some reason the phone was trying to flash to the wrong partition and wouldn't let me change partition, then randomly out of nowhere it did, so i was finally able to reinstall the stock rom and twrp and am now fully rooted with no issued at all.
Thanks again.

Soft bricked OPO - Stuck in Fastboot mode

Hi. I dropped by OPO recently and had to replace the screen + digitizer myself. After doing it, i decided to wipe my phone and re-install Android again. I did a factory reset, flashed a custom rom, gapps and a kernel and i am not able to boot into the OS. When I reboot the device or power it on, I always end up in the Fastboot mode. I am able to get into recovery, but no matter what I flash, whenever I hit reboot into system after flashing, the phone goes back to Fastboot mode.
When in Fastboot mode, I'm able to flash stock images of 44S , but any reboot doesn't take me to Android, it keeps pushing me back to Fashboot. Flashed multiple TWRP versions, tried restoring to 44S/38R through fastboot, but none of them work. Any restart takes the phone back to Fastboot. Any ideas on how this could be fixed?
Any help is much appreciated.

HELP! Bootloop after flashing TWRP

Hey folks,
my S10e (G970F) is bootlooping after flashing TWRP via Odin. The flashing process via Odin did PASS and I could enter TWRP afterwards because the file "Encryption_Disabler" needed to be installed while still in TWRP but I messed up since I've forgot to put that very specific file to the internal storage before and my PC doesn't seem to mount the S10e after being in recovery mode (TWRP). I was cursing myself and in a fit of distress I decided to reboot the S10e into system and that was when it doesn't boot past the SAMSUNG booting screen anymore. I'm stuck with bootlooping.
As for now, I can enter the download mode , my bootloader is unlocked and I'm back on stock recovery but the device deprives itself from booting up which resulted in a never ending bootloop. And let me tell you, bootlooping can cause extremely distress and you feel like sighing every other seconds because it keeps messing with your brain.
Can you guys help me out here? Thanks for your efforts!
I've managed to fix it myself. YAY! I'm happy!

Device stuck at bootloader unlocked screen

Today I had a strange issue with my Oneplus 7 pro GM1913 running OOS 9.5.5, device unlocked, twrp and rooted. My device ran out of charge and was turned off. When I plugged into the charger, it boots up and for a few second the oneplus logo and charge the device for some time page came in and then the bootloader unlocked screen came in. I haven't charged the device offline after the battery ran out, it was my first time and i thought it was supposed to be like that. But after some time also it was on the same page. Then i plugged out the device and it was stuck on that page. I tired hard reboot, tried to connect to computer. Nothing was successful. Computer showed unknown device and failed to successfully connect. Not recognised as adb device shown nor fastboot device. Then atleast I tried entering into fastboot mode by pressing power button + volume up. At that time it rebooted into system and then everything was okay. But then i noticed i also lost the twrp recovery. Then i had to flash twrp through magisk manager.
Anyone has any idea what happened? Thanks in advance
You have to flash magisk again after flashing TWRP.

Stuck at the bootlogo
Hey guys, i hope i get some help from here.. tried to root my one plus 7 pro international version installed twrp everything worked fine... and after that i tried to reboot in system mode.. now im stuck at the bootlogo with the red middle dot and the 2 white ones. i cant even turn it of now.. no command are working... can anybody help me to fix this pls?
Thanks!!!
I had exactly the same problem. System was running fine with just Magisk installed (I boot TWRP with fastboot on a computer).
Then I ran completely out of charge, and the OP7Pro wouldn't boot anymore: at power on, it shows briefly the OnePlus logo, then displays the boot loader unlocked warning for a very long time (a few minutes), then goes to the bootloader menu.
I can boot TWRP and unlock the data partition. I will try flashing the stock boot and see what happens (and report).
Edit: I had to reflash stock boot and system to have the device boot again.

I figured it out. basically when i get to the above attached image I was required to hold volume up+down+power key until the fastmode doesn't comes up. It will take 20-25 seconds. So you will be required to hold it for that long.

Huawei Watch 2 Pro (Shawshark) stuck in horrible bootloop

My relatives have gotten this watch gifted to them a while back but it was in chinese so to get it to English I had to unlock bootloader and flash the room. But while doing so I by mistake flashed twrp instead of booting into it on the Recovery Partition right after unlocking bootloader and after rebooting, it was stuck in a horrible bootloop. Why is it horrible?
So the problem is, it keeps booting into twrp, fails to mount data cache and everything, shuts down and reboots again, shows a warning that it can't detect an operating system and continues to boot into the same twrp recovery and so on. When I try to boot into bootloader, it says to go to g.co/ABH and read instructions to proceed, but after holding down the button to continue to boot, it goes back to the same bootloop.
I cannot boot it into bootloader or get it into fastboot, I can't do anything in twrp and I can't boot into os (cause of course, there is none). Does anyone know how I can fix this? I've been struggling for 4 hours with this today. I'm really scared that I've completely bricked it and can't restore it .
I can see it in adb devices while it's in twrp and twrp is freaking out then shutting down, but I can't even side load a rom to even install something I can boot into.
Link me a thread if there is one where this problem gets fixed or help me please. Thank you!

Device stuck in boot loop with no access to twrp or usb debugging

Hello everyone, I was wondering if anyone might be able to provide some assistance to help me solve my problem here. Basically I was attempting to flash havoc os to my oneplus 7 pro and I think I wiped both the a/b partitions by accident as now it’s stuck in boot loop.
basically it will constantly boot loop where it goes to the unlocked boot loader warning and then reboots. If I attempt to boot to recovery, it will flash with the twrp screen for 1-2 seconds and then reboot. Will boot to fast boot mode but cannot enable usb debugging.. any help would be greatly appreciated, and If anyone needs me to clarify anything I will do my best but its been a week or two since it happened and I can’t seem to find a working solution anywhere. Thank you.
I know this is an older post, but as a thought, when you go to the fastboot menu, if you wait, does it reboot there too?
If so, I think this may be your power button acting up. I had that problem with my phone. I could boot to fastboot or recovery, but couldn't stay in them long enough to do anything. First time it happened, I took the phone apart and disconnected the power button and I was able to get it to boot up successfully. Next time it happened, I just hit the power button multiple times until it started booting up properly.
If this is not the case for you, I would try to fastboot boot the latest version of TWRP rather than from the recovery process (holding down buttons and hoping it boots). I've read that on some devices (with older versions of TWRP), it was recommended to fastboot TWRP rather than flash for better compatibility.
