Moto E 1st gen bootloop and no recovery all of the blue? - Moto E Q&A, Help & Troubleshooting

Hello!
I'm one of the folks who did OTA update on my Motorola Moto E (1st gen) and after that the phone became unusable due to lacking internal space. After that my phone started to restart randomly on daily basis (according to other posts it was caused by almost no free internal memory).
I was so tired of not being able to install apps that I decided to root my phone, I've never done it before but somehow I managed to root it, unlock the bootloader, install twrp, su and then downgraded my phone to 4.4.4, I'm not sure but most likely from there:
https://forum.xda-developers.com/moto-e/general/video-tutorial-downgrade-moto-e-android-t3032738
Anyway it's been working perfectly fine but the phone was still reseting itself (which was odd, having over 500 MB of free internal memory). About 4 months passed by and I'm unable to turn on the phone, it's stuck on logo. Pressing power and volume down gives me access to factory and recovery options but factory worked only once and now doesn't work and when I try to do recovery I'm getting red triangle with Android robot on his back.
How do I fix that? Recovery is unusable. I've got https://dl.twrp.me/condor/twrp-2.7.1.0-condor.img, did
HTML:
fastboot boot recovery-twrp.img
but still recovery doesn't work.
Any hints?
[edit]
I managed to install twrp using "fastboot flash recovery recovery-twrp.img", installed latest Linage OS from official thread on our forums, did everything as in: https://www.youtube.com/watch?v=9esNxdH8-eA and I was stuck on loading screen (blue swiping dot along a curved line), but after like 10 minutes the OS finally booted. Not sure what caused my problems, but they seem to be resolved.
[edit 2]
The OS reseted itself right after booting. I guess I might have some hardware issue after all Can I somehow find out what's the state of my internal memory? I think it might be corrupted. Damn.

XT1225 Boot Looping issues, Lost IMEI and No TWRP Recovery

Hello Everyone,
I own a Motorola quark XT1225 64GB indian version. I had earlier rooted it and installed Lineage OS 14.1 (Unofficial) in it. The installation was without any issues and worked for few months then one day i pressed the power button to turn on the phone and it went into a boot loop and nothing would work. i gave it to a repair shop and he installed android 6.0.1 in it and gave me back. But my phone wont connect to WIFI and later i found out that there was no IMEI or any network related information left in it. only the OS booted and nothing else was working. Even the Developer options were not available as for some reason tapping the build number was not giving any result. he refused to fix it. I tried a factory reset from the settings menu with no result. even the recovery was not available any more in the phone. I tried installing new android stock images both for android 5 and 6 first from RSD lite and fast boot mode which kept failing and then i tried it using the command promt. After installation was complete the phone rebooted and android appeared with erasing written under it but then it went into boot loop and would keep restarting every time android appeared. I tried installing TWRP recovery from the command promt the initial image of the recovery appears but then next second it says unable to mount data and keeps rebooting again and again. Kindly suggest ways to fix my OS as well as have my IMEI restored.
Really need help.
Thanks a lot.

SGP311 boot loop (might be HW bricked)

So mom dropped off her old Xperia Tablet Z SGP311 as a "gift". It did not work for her anymore, so if I wanted it and could fix it then I would have another tablet in the pile.
Her description of what did not work was what you would expect from a non-techie aka "some error turned up but I cannot remember what the screen said, so can you fix it?".
In the beginning I thought the problem was the common USB/charging problem, however I feel anything about this tablet seems different than other Android tablets, so after finally managing how volume buttons along with power buttons work, I could rule out it was a charging issue.
Getting the Tablet to boot it seemed that it had been updated and was booting into OS doing the "optimising applications 1 out of 258". However going to the step "starting applications", then tablet would just reboot a few times and then start over with optimising applications, starting applications, reboot and repeat all over. So some sort of bootloop.
I then used Sony's Xperia Companion to repair the tablet from fastboot (volume up + power) which succeded until it should reboot the tablet, then I was stuck in the same loop as above.
After a few tries I then managed to unlock bootloader and get TWRP 3.2.2 booted onto the tablet (booted NOT installed since I have no root).
With TWRP I tried deleting Dalvik cache etc., which did not help the situation, same bootloop.
With TWRP I then gave LineageOS a shot, but LineageOS experience kinda the same bootloop (both LineageOS 14.1 and 15.1).
LineageOS boots fine and proceeds with the fresh install questions (region, timezone, Internet access) but as soon as I hit next on the "Location Services" page the tablet will reboot.
Since this tablet has no value to me, I have tried deleting all data on all partitions from TWRP, I have checked the filesystem with e2fsck on the tablet which shows no errors, but in any attempts it simply reboots at the same stage every time.
So are we at the level where this might be some internal hardware failure (GPS/WiFi chip, NVRAM)? Or is there any suggestions of what else to try other than throwing this to recycle bin.

Emmc error in boarddiag

Hello guys, hope you doing well... I've an serious problem with my main phone. First, thank you for taking the time to read my story.
I have an Sprint LG G3 32GB since 2 monts ago and it was performing very well. Then I've flashed Resurrection Remix and a custom kernel on it and everything worked perfectly until some days back. I came back from school and left my data opened since the morning and the phone was discharged. I putted it in charge and was sending some messages on whatsapp. I tried to play some music but the phone was not making any sound and it locked on lockscreen and wasn't able to unlock it. Thought it was an OS bug and tried to reboot. While trying I felt asleep and left the phone in charge. Some hours later, the phone won't just boot and in TWRP, it shows Internal storage OMB.
I've waited some time and tried again then it came and I've restored the KitKat stock ROM. After that, the phone started bootlooping and freezing in logo. I was always facing Internal storage OMB and corrupted partition (cache, userdata, system, etc...).
2 days after, I've managed to flash an stock and fresh install TOT via LG FLashTool. The first time, the process didn't worked and I re-tried and then it flashed successfully the phone rebooted to Factory Reset Status 2. I've rebooted and it started with the QHS 9008 Loader COM. I've used boarddiag and restoring stock partitions and tried to flash again via LGFlashtool but the phone will just reboot during flashing in Download Mode and come back in QHS Loader.
This morning, I've sucessfully restored everything and the phone even booted up. It was discharged so I turned it off and left it in charge. Since 3 hours ago, when I try to start the phone, it may freeze on LG Logo or just stay in QHS with everything black. Managed to try AP CHECK and EMMC TEST but AP Pass and EMMC gives me "Error while trying to read partition from EMMC". Basically, that means that my EMMC has fried out or have been damaged. BUT, SURPRISE, sometimes the phone will boot up normally and work for 2 to 5 minutes and power off again and going back to QHS.
NOTE:
-I can't access download mode
-I've flashed the ZV6 cause that's the only ROM who restored via boarddiag and flashed successfully via Download mode
- Also, I've remarked that in the storage page in settings, the phone will show 9GB available and put 21GB in MISC unusable. That's anormal...
THANKS YOU for reading until here.
This is my main phone, any help would be appreciated thanks a lot for responding.
SOLVED
Unmonted the phone and heated a little bit the EMMC chip and putted an small paper in other to make some pressure and remounted.
Everything worked nicely.
Am know facing unlocking issue

New Post ... Old Nook HD+ Boot Problem

My Nook HD+ bootloader won’t launch the installed OS, CM 13. The Nook screen appears, and then gives way to the Cyanogenmod Universal Bootloader. After a bit the blue android image appears. It pulses normally at first, then the pulsing pauses, and finally the process starts all over … and over, and over, and over!
At first I thought there was a problem with the OS, so I booted into recovery (TWRP 3.1.1-0) and tried to flash CM 13 for ovation. That didn’t work, so I tried flashing other ovation ROMs. None will install. They all report an ERROR 7. I’ve attempted to work around that error, but none of the methods I’ve found made any difference.
It seems that I may have to reinstall the factory/stock ROM, and I’m okay with that. But it seems I can’t do that either. The stock rom download is in a CWM backup format, and I have TWRP, not CWM. So I tried to flash CWM with TWRP, but in order to make that work one has to reboot into recovery via TWRP, The problem here is that the TWRP boot menu has just two options … System and Power Off. The Recovery option that is supposed to be there isn’t!
So I tried to replace TWRP with CWM via ADB. I can sideload a CWM zip without a problem. I then issue an ADB Reboot Recovery command. But, instead of rebooting into recovery, the bootloader launches instead. As a result, when I go into recovery it’s still TWRP. I’ve also tried powering on with the CWM bootable image file on an sd card, but no matter how many times I power off and back on, my tablet never recognizes that the file is there and my problem persists.
Is there a way to boot into CWM or swap CWM for TWRP in a situation like this? I’ve seen postings that suggest fastboot may the be solution, but that requires that debugging be enabled, and it was not enabled when my problems began. Apparently there is no way to enable debugging without launching the OS.
Help!
Update:
My Nook HD+ has not rewarded my attempts to bring it back to life Perhaps I’ve made things worse. I certainly haven’t made things better. Here’s the latest.
When booted up, little or nothing has changed. At bootup the Nook screen is followed by the Cyanoboot Universal Bootloader screen. Sometimes it gets no further, and reboots. More often the android image appears with a halo pulsing in the background. Sometimes the halo pulses a couple of times before the device reboots. Sometimes is pulses a bit longer before rebooting. Sometimes it never stops pulsing (until I press and hold the power button to shut the bloody thing down, that is).
Thinking the problem was related to the OS (I had been running android 7.1.1 (an unofficial HD+ release, but from a very reliable source), I've tried in vain to flash another OS. I've tried multiple android releases, from 7.1.1 down to 4.4.4. I've also tried flashing several versions of the HD+ factory stock OS. I’ve done all this using TWRP, and also by booting CWM from an sd card. No matter which recovery I've used or which OS I've attempted to install, the process always ended with an ERROR: 7.
So, I got my hands on a good Nook HD+ running android 5.1.1. I made unbundled TWRP backups of the System, Boot, and Apps partitions using release 3.1.1-0. The System and Boot partitions each restored without a problem. The Apps would not restore, ending with “extractTarFork() process ended in ERROR: 255." That error probably isn’t related to my problem, which is that I can’t get the system to boot up. More telling is the fact that after successfully restoring the System and Boot partitions using the backup from a good HD+, when I power up the device appears to be launching 7.1.1, not 5.1.1. The android image displays in portrait mode on the good HD+ running 5.1.1, but displays in landscape mode on my HD+ ... and the boot loop continues, of course.
At this point, at the $7.25/hour minimum wage rate I’ve spent enough time that I could have earned many times the original cost of the HD+. So, am I giving up? HELL NO! Now it’s personal!!
My HD+ boots into TWRP flawlessly, so I still have that going for me. My HD+ is not rooted and did not have USB Debugging enabled when it crashed, so any solution requiring SU or flashboot is a non-starter. Otherwise, I’m willing to give anything a try. Maybe I should be looking for an exorcist?
Thanks for reading this, and for your suggestions, words of encouragement, and expressions of sympathy.

Question [Solved] BOOTLOOPED phone after A12 update. NANDroid restore caused Camera/Fingerprint to become completely disabled

================
Update 4: All issues fixed! I'll briefly explain all my issues, what I think caused them, and how i resolved them incase it helps others.
(You can find 3 posts of my original issues by scrolling down, but TL;DR)
4th post (at the top) : Brief summary of all solutions for my 3 big issues.
3rd post: nandroid backup applied, fingerprint+camera stopped working. Fix: reflash Persist partition manually, using the "persist_image.emmc.win" file from the TWRP backup folder
2nd post: Bootloop due to... miscelaneous user errors. Fixed by using TWRP reformat then restoring to nandroid backup.
1st post: Bootloop due to wrong boot.img. Fix: reflashed boot.img downloaded from post#8 of this thread
================
context: I'm using a DN2103 (international Nord 2) phone variant, which received the .A12 operating system update in the past couple days. Meanwhile, Indian users received the .A13 update.
In my process to unroot and update to the new OTA operating system, I used the stock boot.img provided by an indian user, which was the boot.img for the .A13 update which was incompatible with the european .A12 OTA operating system.
Basically I had the wrong boot.img
BOOTLOOP FIX: (this assumes you have the appropriate MTK drivers and ADB drivers, if not, lookup how to get those installed or you can't run ADB or fastboot commands)
Download the correct stock boot.img for your version: I got mine from https://mega.nz/folder/fZx2nBaR#Q33lJstFRMQg6_0j7Z0TJw
Transfer the new boot.img and a copy of vbmeta.img (optional) into the folder where your adb.exe is located (usually platform tools folder). I use the stock vbmeta from the OTA updates from from: https://mega.nz/folder/rQhhHQpA#nNHvPlmzBXwPjmaFpuDa2Q
Reflash your downloaded stock boot image using commands "fastboot devices" to see if you device responds, if it does, then send "fastboot flash boot boot.img".
Reboot phone. If it's still stuck in a bootloop, try flashing vbmeta with command "fastboot flash vbmeta vbmeta.img" similar to the boot image flash.
If you don't have ADB and Mediatek drivers installed, but have TWRP installed, you can do the same from Step 2: Transfer files onto phones internal storage, and step 3) Use the install button in TWRP to flash boot.img to the "Boot" partition. You can also do the same for vbmeta.img to the vbmeta partition if you phone doesn't boot after that.
Hopefully it works. If not, I'm afraid you'll need to boot into TWRP, (if you ahve it installed) and press Wipe, and wipe data/dalvik/cache, then press Wipe again, and reformat the whole phone. If you can get into stock recovery, then you can also use that to format all data. That should get your phone completely wiped to fresh and should boot into a welcome screen, for first time setup.
(note: If you used TWRP to restore or wipe all partitions, PERSIST partition will not be functional leading to camera/fingerprint issues, solution below)
To get into TWRP whilst your phone is bootlooping, you can hold volume up + power to force your phone to reboot, as soon as logos fade, you can press volume down + power to get your phone into fastboot mode. Connect PC, open powershell terminal, phone should respond to "fastboot devices" command. You can then send "fastboot reboot recovery" comand to get it into TWRP.
Fix for Fingerprint scanner and Camera not working:
Apparently when you restore to a TWRP backup, TWRP does not correctly flash the PERSIST partition, so you simply need to do it manually. The persist partition contains sensor calibration data for the fingerprint and camera.
Steps I took for this fix
1) Went to my nandroid/TWRP backup which I had saved to my PC
2) Located file "persist_image.emmc.win"
3) On PC, open ADB terminal in the same folder containing the "persist_image.emmc.win" file (on windows shift+right click to open powershell)
4) Connected phone to PC, sent command "adb devices" to check if device responds, if listed, sent command "adb reboot bootloader" to get device into fastboot mode
5) Sent command "fastboot devices" to see if device responds, if listed, sent command "fastboot flash persist persist_image.emmc.win"
6) Took 1.5 seconds to send 54000 ish KB. Shoud see OKAY's on powershell screen
7) sent command "fastboot reboot" to boot phone up.
Big thanks to @HofaTheRipper for providing the stock A12 boot.img and the persist partition fix!
===============
Post 3 (you can find original post and 2nd post below too)
Phone no longer bootloops, but fingerprint scanner +camera no longer work.
Solution in post #24 of this thread by @HofaTheRipper
Basically caused by TWRP not flashing the Persist partition correctly, so it's solved by finding the "persist_image.emmc.win" file from a Nandroid backup, and flashing that manually.
===============
So phone no longer bootloops which is great, but the camera and fingerprint sensor currently don't work or respond at all
Fingerprint scanner: Trying to register a fingerprint results in the phone vibrating nonstop saying "TRY AGAIN" in big letters, with small letters "unable to complete finger print settings please retry". It continues to vibrate until the settings app is closed or minimised, and won't register a new finger at all. In fact, the fingerprint sensor doesn't even light up, and hte vibrates are the kind of vibrate the phone does to let you know theres an "error" or "not accepted try again" kind of vibration.
Camera issues: Using the option to register facial recognition in the settings app can't open camera due to error message; "camera being used by another app. Please retry later." Even just opening the stock camera app itself instantly crashes. All other apps that use a camera say they do not have permissions to access the camera, despite very clearly having been granted permission.
What I've tried so far:
-Rolling back to A11 OS
-OTA updating afresh back to A12 (again)
-using TWRP wipe darvik/cache/data
-using TWRP to reformat all data
-using settings app, android's wipe data and factory reset option
-googling and searching xda a tonne to find any possible leftover remnants of fingerprints left behind from my previous OS install
One of the thread i found suggest there could be fingerprints i could delete; https://forum.xda-developers.com/t/...ng-or-not-working-after-flashing-rom.3858845/ but I can't find the relevant files on my device.
My 2nd bootloop did indeed force me to do a TWRP wipe+reformat whilst the device was encrypted/ had a pincode, so perhaps theres some kind of security feature that's getting tripped here.
I tried the backup to Nandroid on A11, then used the OTA update to update to A12, so something tells me that perhaps a stock os reflash wouldn't help in my case.
It would be nice to have to full stock OS's for A11, A12, and A13 just to try them out and help troubleshoot.
Any help finding a solution to the camera/fingerprint issue is appreciated, or any help hunting down where I can download the full OS versions. (even for older OS's for the nord2)
My new working theory is perhaps android's innate permission system is messed up, or there's some data stored in the security module that isn't being wiped that's withholding these features relating to the fingerprint/facial unlock security features.
Every single app that tries to access camera is giving back a "please grant permissions" error, despite very clearly have permissions to use the camera.
Any ideas on how to resolve this would be great!
=============
EDITTED: Part 2, BOOT LOOPING AGAIN. Flashing boot.img doesn't resolve bootloop this time around and the phone has a pincode that I forgot to remove.
This is most likely caused due to magisk trying to modify the boot.img for the wrong stock A13 boot image, which no longer existed as I had flashed in the boot image for stock A12 as part of my first bootloop fix; But the phone still had its old data and magisk installation running.
Solved it by using TWRP Wipe option to factory reset and format data. After that, I was able to get the device to boot - current issue is just that the camera and fingerprint sensor don't work
=============
SECOND BOOTLOOP DETAILS; (resolved)
After flashing boot.img for A12, I managed to boot the phone, solving the initial bootloop. However, it didn't take me long to notice issues, and walk straight into another bootloop.
Series of events;
-Phone asked for initial setup including forcing me to apply pincode (can't skip that step)
-Part of pin setup, noticed fingerprint reader not working (vibrates and error message "unable to complete finger print settings please retry")
-Part of pin setup, noticed comera not working during facial recognition step (error message "camera app used by another app")
-Noticed camera app crashes instantly.
-forgot to remove passcode as was in the app drawer and was exploring what was going on, got distracted.
-I checked settings page -> About phone -> Phone is running A12
-checked for latest update to see if A13 is available for OTA update in my region; Nope. "You are up to date!"
Then I made the big mistake. As I was in the app drawer and just checking the state of the phone, and concerned about the fingerprint scanner and camera app not working, I found the magisk app still in the app drawer. Curious as to magisk's state; I clicked on the app and launched it.
-Note; my initial boot loop (orignial post below) was caused when I clicked magisk for the first time after rooting phone, let it the magisk app do it's first time setup thing about "installing full version"; As soon as i hit reboot it bootlooped phone. Now that i resolved that bootloop, I figured magisk might be fine now? Was curious to see what happened to magisk hence my temptation to click it and see. Didn't think to remove pincode first.
-This time, as soon as I clicked magisk, the screen IMMEDIATELY went black, popped up a message saying "restarting", and the phone immediately rebooted.
Phone is now stuck in bootloop again. And to make matters worse, phone has a pincode, which i didn't have time to remove, so stuff is encrypted.
Obviously I tried what worked before; Booted to TWRP, this time, TWRP had to ask for my pincode to decrypt device, but accepted my pincode and decrypted User0 successfully.
-Flashed boot.img for A12 device again, rebooted.
Still stuck in bootloop. Same symptoms as before; Stuck on 2 rotating white dots around the big red dot; If i wait long enough it reboots and shows 1+ symbo land orange state warning message, after a few reboots it boots to TWRP.
So now I have a pincode, and same problem as before, aka bootlooping, TWRP is still installed and working, but also probable issue with fingerprint scanner and camera (remnant from last bootloop perhaps?)
Most likely because magisk is still set to reboot when launched and to modify the boot.img, as thats the step where my first bootloop happened.
===============================
ORIGINAL POST BELOW;
initial bootloop was fixed by flashing boot.img for A12 provided in the comments below
Supposedly the boot.img I originally used was for A13; Supposedly these boot images are similar enough that they seem to mostly work for each other, until magisk touches it - issues with magisk in my 2nd bootloop post above.
================================
My Nord 2 is stuck in a bootloop
TL;DR
I was running a rooted .A11 update just fine, updated to .A12 following a guide, lost root access, so re rooted phone just like i originally did. Got to the point where i used TWRP to flash magisk.zip, that part worked fine, phone booted just fine, launched the magisk app from the app drawer, let magisk install full version, it automatically rebooted, then immediately got stuck in a bootloop.
Full story for troubleshooting context: (in case you can see where I goofed)
- I updated from .A11 to .A12 successfully which meant the phone was unrooted; Followed @pankspoo 's guide except using my own OTA update.zip after clicking download in my settings app (I'm EU region); https://forum.xda-developers.com/t/...rooted-nord-2-any-incremental-update.4347813/ (following the comment to find the update.zip folder at /data/OTA-package/update.zip
- Verified my phone was fine running the .A12 update properly; opened settings app, checked about phone page, .A12 listed and "newest version installed". Launched the root checker app and confirmed phone was "not rooted" anymore so proceeded to follow @pankspoo root guide again https://forum.xda-developers.com/t/tutorial-twrp-and-root-nord-2.4340477/ , the same guide I originally used successfully back on .A11 (worked great!)
- Got to the point in the guide where I flashed and installed TWRP, it worked just fine. Nothing unusual so far.
- Used TWRP to flash magisk.zip, also worked fine. Still nothing unusual.
- Used TWRP to make a full backup (ticked all boxes) here, but this backup file seems to be GONE (did not transfer it to PC)
- Rebooted to system, phone booted just fine, found magisk icon in the app drawer, launched the magisk app and let it do its first time setup thingy, where it "installs full magisk" and so on. I let it do it's thing, eventually it rebooted the phone;
- Phone now immediately stuck in bootloop. Don't know if Magisk even installed itself properly; Waited out the first bootloop long enough that the phone ended up rebooting multiple times and ended up automatically booting into TWRP so its not a "just wait longer" issue.
Symptoms:
Its a standard bootloop aka stuck on 2 rotating white dots around the larger red dot. If i wait longer enough, phone reboots, initially shows the 1+ icon and the "orange state not trusted boot in 5" message that we're probably all used to seeing. After a few reboots it eventually ends up booting into TWRP.
Holding Volume up+power forces the phone to reboot, but obviously, still gets stuck in the same bootloop.
Holding Volume down+power when the phone reboots places the phone into fastboot mode, which lets me connect my computer, open the powershell window, and use the "fastboot reboot recovery" command to get into TWRP instantly.
TWRP is working fine! I can still flash things and do all the normal stuff in TWRP... But not idea what to do right now.
Stuff I've already tried: (against my better judgement)
-Clicked "restore" button on TWRP; I made a TWRP backup whilst on A11, and the device does not seem to want to boot with that A11 boot image and old nandroid restored.
-renamed magisk.zip file to uninstall.zip and used TWRP to flash it; Nothing seems to have happened. Error code: "magisk will not be uninstalled please uninstall manually"
-Tried reflashing magisk.zip normally.
-Tried to manually reflash my old boot.emmc.win file form TWRP backup on the phone (this is most likely my old A11 boot image)
How do I proceed from here? All help appreciated. Edit: Turns out, i was flashing the A13 boot image from indian devices whereas I have a phone running A12. Bootloop issues were instantly resolved when the A12 boot image was flashed again;
However, magisk was still set to reboot the phone and patch the boot.img so I ended up having to wipe all data to get rid of magisk and stop magisk from corrupting the boot image.

I did not transfer it to my computer so no idea where it went.
-renamed magisk.zip file to uninstall.zip and used TWRP to flash it; Nothing seems to have happened. I did read the text on the phone and saw a bit saying "magisk will not be uninstalled please uninstall manually" so i guess something went wrong.
-Tried reflashing magisk.zip normally.
-Remembered I made a TWRP backup a few weeks ago, so used TWRP's Restore feature to restore to that backup. This is a backup was when the phone was running .A11 and obviously working fine, not sure if that matters much. (didn't help either so I assume TWRP backups don't restore stock os or anything like i thought it did?)
Obviously, none of the above resolved the boot loop and I have no idea what to do from here. Phone still stuck in the same old rotating 2 white dots around the larger red dot animation.
Not sure if I should reflashed anything at all as I'm pretty inexperienced. Scared to try anything else without consulting you guys for help first. Most google results for bootloop fixes seem super sketch and outdated so I'm scared to try much else, and already thinking I may have made things worse with the things I did already do.
How do I proceed from here? All help appreciated. Not sure if using .A12 was the wrong call here but i suspect it was.

Hey thanks so much for posting the guides!
OHHHHHHHH I see now. I updated to .A12 using the European OTA update.zip file, and the boot.img I used was from your guide which you said was
"2) upgrade from v11 to v13(indian)"
That must be why. Do you have a boot.img for .A12?
Or do you perhaps think I should download .A13 because it's more recent?

Do you mean I have to find the boot img for A12 and nothing else will work? I'm not too sure where to find boot images.
Do you think If i download the update.zip for A13, I can flash that, while the device is bootlooped, and it might work? Would I need to use incremental update from A12 to A13 or would I use incremental from A11 to A13?
Also, I don't know how to download from your telegraph links, it doesn't seem to work for me, clicking the file doesn't download.
Is there another way to resolve the bootloop, including wiping all data just so the phone works again?

@Zombnombs u got it do it now
The a12 boot image worked a charm! Thanks guys!
Okay. Phone's in a bootloop again! Literally about to cry or something
I think I need a recovery image or something? OR a way to get phone back to completely stock.
Full story;
After flashing a12 boot image, phone booted up andI checked
-Phone was running A12(checked "about phone" in settings app)
-Root access was granted (used "Root Checker" app)
-Magisk app still in the app drawer
At this point for some reason I ran the "click here to set up your phone" because the popup/notification was annoying. During this, you're forced to enter a passcode. I never got the chance to remove the passcode so the device is now "encrypted"
Things I did notice during this time whilst exploring the phone;
-Fingerprint scanner is totally broken; The white light doesn't even appear, phone vibrates constantly like it's error'ing out, and shows "unable to complete finger print settings please retry" as an error on screen
-Facial recognition step of the setup wizard also had a strange error message, saying "Camera is in use by another app".
-Camera app immediately crashed when I click it to check why facial recognition was failing.
Anyway, still thinking i was just exploring the state of the phone, I decided to click the magisk app in the app drawer to see what was happening with it;
IT INSTANTLY RESTARTED MY PHONE. Screen went black, the words "restarting" popped up and the phone rebooted without any chance for me to stop it.
And what do you know, PHONE IS BACK IN A BOOTLOOP.
First thing I tried was booting into TWRP again, which had to decrypt User0 now that I have a passcode on, but that was fine, because entering the pincode worked. I flashed the boot.img for A12 again; But it didn't help.
What should I do now? boot.img didn't work, I'm really inexperienced with this stuff. I'm new to rooting, but keen to learn and get into modding/rooting androids so I guess this is a good learning experience, albeit extremely frustrating >.>
Due to issues with finger/camera, and the fact it's still bootlooping anytime I click magisk, best option is probably to restore to complete stock? Google search says I need a recovery image for my device, but i can't find Oneplus's recovery image for Oneplus Nord 2 so I guess I'm back to asking here for help.
@HofaTheRipper @pankspoo (sorry for the tag) do either of you happen to have a recovery image?
^ Phone is back in a bootloop.
Updated the initial post again because this problem is getting kinda long winded.
TL;DR for my 2nd bootloop boot.img isn't working to fix the bootloop. Bootloop occured after clicking on magisk app, which instantly restarted phone without warning (before I could remove pincode), and put the phone into bootloop state.
Phone has a pincode on it now so TWRP has to decrypt User0, not sure if that's the reason why boot img doesn't resolve this boot loop. Even though I can enter pincode when TWRP asks for it, and TWRP manages to decrypt User0 successfully.
I did notice after fixing first bootloop, fingerprint scanner and camera didn't work, so it's probably best to just start over anyway. Add in the new bootloop, and I don't really see any reason to continue with this attempt at the root, probably best to fully reset to stock and try again, try get the fingerprint and camera working again.
Recovery Image time I guess?
Ok

TL;DR of what worked for me was making sure i had the right boot.img flashed and then also flashing vbmeta afterwards. That's all it initially took.
I also seemed to solve another one by using TWRP to wipe cache/dalvik/data, then also pressing wipe, and hitting reformat (losing all data)
Finally I think if you made a TWRP backup, you should be able to restore to that, then wipe do a dalvik/cache/data wipe.
Just what worked for me, I'm pretty new at this stuff so I literalyl don't really know what I'm doing either

how do you enter recovery mode without waiting for a couple of reboots ?

You can hold power+vol up to force a reboot, and when the logos disappear, hold Vol down + power to enter fastboot mode. You can then plug in your computer and send powershell window to send "fastboot reboot recovery"
