NEED HELP

I have a brand new Pixel XL from Verizon that I received today and was successful in unlocking. However, I tried to root and now I am stuck on bootloop. I cannot post in DEVELOPMENT because I haven't posted here in years (haven't had ANDROID in a while). Can anyone help? I am able to access via fastboot (I believe) but I must be flashing the wrong images. I don't want to brick this nice new day-old device. I have been at it for 5 hours via research on my own, but now I am looking for someone that can help me via P.M. or what it may take. I really want to get back to enjoying this device! Thanks in advance!

Read the third post in the thread below to get set up and back to stock. Then we will work on root. If you tried to root and you bootlooped it then you used the wrong​ SU.
https://forum.xda-developers.com/pixel/help/stupidly-bootloop-help-t3554242

1. Download a ROM. A stock version is probably in the forums somewhere if that's what you want.
2. Download TWRP image and zip from the TWRP thread.
3. Download SuperSU from the SuperSU thread.
4. Download a vendor image. There's no "official" vendor image thread AFAIK, but you can grab one from the Pure Nexus rom thread. NMF26V is compatible with all 7.1.1 ROMs & stock.
Now you have two options:
Fast: Put the ROM, TWRP(zip only), SuperSU and vendor image on USB flash drive, then connect the USB 3 to USB C adapter to your flash drive. Don't connect it to the phone yet. An external HDD/SSD should also work if that's all you've got.
Slow: While in TWRP(Instructions below) push the ROM, TWRP(zip only), SuperSU and vendor image files to your phone through ADB with "adb push C:\file_path\ /sdcard/" sans quotes. You will need to do this for each file, or alternatively push a folder containing the four files. adb file transfer is very slow.
5. Boot your phone to the bootloader, and connect it to your computer. This can be achieved by holding volume down and power from an off state.
Note: If your device is still bootlooping you won't be able to get to the bootloader. Hold volume up and power until the device shuts off to get out of the bootloop temporarily, then boot to bootloader.
6. In a command window, "fastboot boot twrp.img"
7. Connect your flash drive to your phone if you chose that option, or push the files through adb if you chose that option
8. Flash TWRP zip, ROM and vendor image. STAY IN TWRP
9. Return to TWRP's home screen > advanced > file manager. Scroll down until you see 'fstab.marlin'(in the root '/' directory). Tap on 'fstab.marlin' and delete it. Skipping this step means SuperSU won't install.
10. Flash SuperSU zip, reboot to system and you're done.

Just thought I'd update you...And I know I sound like I have no idea what I'm doing but traditionally I've never had issues like this But I am trying to get ADB to show the flash-all command. The one I have installed doesn't show that feature so I can't follow the tutorial. If you have a direct link to what I may be missing I would appreciate it otherwise I will update you once I figure it out.

Thanks for your assistance. I now have root installed and I think I'm good except for one thing. I keep thinking TWRP is installed but for some reason when I reboot to bootloader, then select reboot recovery mode, it takes me to android recovery. I am used to recovery taking me to TWRP. I know TWRP works but I feel like I'm temporarily flashing it each time or something. I even installed the twrp app and I see I can flash zips that way, etc, but I wanted to know if you knew how to make the phone boot to TWRP in recovery? Or is that necessary?

I dont do it that way on this phone. TWRP and SU are modifying the same parts of the phone, and there are cases where it could conflict. Rare, not a big deal, but since i don't need TWRP installed i don't.
To install it ypu first boot to it.
Fastboot boot twrpFilename.
Then from within TWRP you install the TWRP zip.
Make sure it is TWRP RC1

All set
Thanks again for your help. I am running pure ROM as I mentioned and I seem to like it. Do you K or if Franco works with Pure or do you have a suggestion on a good rom/kernel? Is there anything else that you can suggest I should be using with the new phone? I remember there used to be tools that you could install that allowed you to customize the system even further but the name escapes me. . Is there anything like that or even a theme tool which is a must have when you are rooted and running custom roms? No big deal if not. Very happy with where I stand now. Really appreciate you getting me back up and running!

You are most welcome. I don't ROM so I don't know what kernels work with what roms for sure. But my understanding is that they are all pretty universal. I run stock with Franco.
Other than that i dont mod much. Ad blocker, black themes and a few adjustments to Franco.

Im running pure and elementalx with excellent results.
?Tapped from my pure pixelXl?

have you ever seen an issue where the phone boots to twrp even though everything was working fine? It starts happening if I do a restart. Then no matter what it boots into TWRP unless I wipe again? I believe it's happening after I flash root but I'm going out of my mind with trial and error. Any help would be appreciated.

HELLO!!! I understand any frustrations you may be having, as the pixel devices have changed a good bit for us as far as development. Anyways. I'm just going to throw some knowledge out there, then proceed to help get you up and running!
You couldn't post in the development section because of your post count, but even if you could, it would have been in the wrong section and it would have been removed, or moved to the questions section.
Also, I see someone has pointed it out earlier, but I'll say it again just to make sure everything is clear. The command you were running "fastboot boot TWRP.img" only boots TWRP temporarily. You are suppose to have two files, one IMG file and one zip file. You boot the IMG file, then once you're in TWRP, you flash the zip file, then reboot to recovery and you will have installed TWRP properly.
With root, flashing wrong files or using the outdated root method will cause boot loops. The correct way to root (again already been said) is the get TWRP up and running, delete the fstab file (see earlier post) then flash SuperSU and reboot. Just throwing this out there Incase someone comes across it, if you manage to boot loop your device due to to rooting, you can fastboot flash franco's kernel and it will fix the bootloop (,but you won't have root) this isn't the correct way to fix it, but it will get you back up and running without downloading the large factory image.
***About to edit this post to continue giving more info***
Here is a correct guide and good template to get you running.
start by flashing a clean factory image, then let it boot and get it set up.
Reboot to fastboot, fastboot boot TWRP IMG then flash TWRP zip using the latest versions (RC1 is latest, pm me for more info).
Reboot the phone to recovery to ensure TWRP stuck.
Go-to advanced, file manager in TWRP and find the fstab.marlin file and delete.
Then you can go ahead and flash the latest SuperSU (I use 2.79 sr3) and when it's done reboot to system and verify root.
After rooting you can go ahead and flash a kernel if you want, I use elemental which you can flash in TWRP, but see the kernel instructions prior to flashing.
Reboot and you have a nice stock ROM with root and kernel.
For flashing Roms, kind of follow the same template, most Roms require you to flash part of or the whole latest factory image.
If your on a clean install, go ahead and install TWRP as mentioned above.
Then use TWRP to install whatever ROM you want per ROM developer instructions.
Side note, some Roms replace the TWRP with cwm or stock recovery, so it's always nice to flash the TWRP zip after flashing a ROM.
After flashing ROM, boot to system to make sure all is well, then boot back to recovery and follow instructions above for root/kernel.
As far as the problem you're having now, it usually comes from flashing outdated SuperSU images. Do a search for 2.79 sr3 and use it to root (pm me if you need help)
You might have to start clean one more time, And flash factory image.

There is absolutely no need to delete the fstab file anymore. That only needed to be done when TWRP was still alpha 2, and almost three versions of su earlier.
ALL roms replace TWRP with stock recovery unless you are using lineage then you will get Cyanogenmod recovery, so reflashing TWRP before booting into system is a must.
If you are flashing root and or custome kernel and end up in a bootloop, flashing the stock boot.img to both slots via:
'fastboot flash --slot _a boot boot.img'
'fastboot flash --slot _b boot boot.Img'
will fix the issue and you will be able to boot up just fine. Again you will have to reboot into TWRP from the bootloader and reflash the zip. When you are done flashing the boot.img's you might as well just
'Fastboot boot TWRP-file.img'
Then install the zip!

Switching partitions in fastboot? Trying to remove root so I can log into snapchat

I read in another thread that I need to 'Just reflash the original boot.img on both a and b to unroot. Log in and then reroot'...how do I do this? I can flash boot.img via fastboot no problem...but how do I switch partitions? Also, this method doesn't result any data loss correct? Was going to do the 'full unroot' option in SuperSU but with the partitions stuff I'm not sure if that will work?
I'm running TWRP RC2 and SuperSU SR3 2.79. Phone is fully setup and functioning other than Snapchat. Went to bed at 5am after taking hours to log into all my apps, configure them again, etc....would HATE to do all that over again...so much that I would stop using Snapchat to avoid it.
Any help would be appreciated.

@blueyes, I saw you help another member out with something similar but not quite...any idea?

You can simply use the in app option it works just fine. Alternatively you can install Magisk without wiping to keep root and bypass Safteynet (will allow you to use Snapchat, Android Pay, etc..) I was running a nearly identical setup to you when I did it. Here's some instructions if you want to try that route https://forum.xda-developers.com/showpost.php?p=71629390&postcount=2394

That certainly sounds better as it will give me the perk of being able to finally use Android Pay. I'll investigate, but worst case I'll do the in-app solution and do the old method of logging in to Snapchat and then re-rooting. Thank you!

tdct12 said:
Quoted from another thread. Anyway I tried it out. Already had Pure Nexus, superuser, twrp RC2, and elementalx installed. Magisk fully working. Here are the steps I followed (no wipe)
Open SuperSu
Uninstall supersu from in app option
Reboot system
Reboot recovery
Flash Magisk zip
Wipe cache/davlik cache
Reboot system (creates bootloop back to recovery)
From twrp switch bootloader slot to the inactive slot
reboot recovery
From twrp switch back to the orignal boot slot
reboot system (these steps end the bootloop for some reason)
You might need to force close your root check app and reopen for it to detect root at first.
edit: Saftey net passed, just checked =)

So...I had different results.
When I remove SuperSU from in-app option, my phone was still rooted. It didn't actually unroot. Is that because I told it to not flash the boot.img?
#7 didn't result in a boot loop...proceeding on...

@IlyaKol you do need to let it reflash the original boot.img. Supersu modifies it to achieve root. Magisk is it's own root you probably shouldn't have flashed it until you verified that supersu had been removed. You can still try removing supersu from in app option I have no idea if it will effect magiskSu. After you remove supersu go the Magisk app (the zip installed it) and see if it's still rooted. If not just try reflashing the zip. All you can do is hope it works out. Once it's installed properly you go the app and enable Magisk Hide, there is a Safteynet test in status page along with root status, I will post a screenshot for clarity

Okay, I'm going back to recovery, will flash the Magisk Uninstaller followed by the SuperSU installer. Then I'll go into the app and this time tell it to restore the boot image but NOT the recovery. Right? lol.
That didn't work so I'm trying other methods to remove SuperSU...I'll report back later as I need to get going and will be doing this elsewhere lol.

@IlyaKol rather than reflashing supersu since the root is not removed you should instead just downloaded the supersu apo from the playstore then try removing the supersu root from there. If you get an "error no SuperSU binaries detected" then it is already removed.

It's still there even after running other tools found on XDA to try and unroot. I'll just flash the boot image manually when I get back home. Magisk sees it as such, not the Magisk root.
Thanks for the other steps...only remaining question I have is do I need to flash the boot image to both partitions? Or is whatever fastboot defaults to enough? If I do, what's the fastboot command for that?

If you use fastboot make sure it's on your current slot. I can't imagine why the unroot wouldn't work. Did you try clearing app data on your root checking app? Did the actual supersu app from play store detect supersu binaries? You might run into some data loss trying to remove root honestly if no methods are working. If all else fails do a wipe and then just install magisk when you've reinstalled the rom of your choice. I know it's not a pleasant solution but it's a solid last resort.

Eh, @tdct12, I finally caved and just ran flash-all.bat to get back to 100% stock. Third time redoing my entire phone (copying all the data back down such as pictures/videos, music, etc. and logging into each app and signing in, etc.). First time I forgot to unlock the bootloader first, so I had to wipe (DOH!), 2nd time was I didn't log into Snapchat before rooting (DOH^2) and now this is the 3rd time. #thirdtimesacharm
Yesterday (round 2) I finished at 4:45am. It's 1:13am now...so let's see how long the third time takes lol.
This time I added unlocked the BL, flashed TWRP RC2/Magisk 11.6 (from your quote)/ElementalX 1.09 right from the beginning lol. Taking no chances.

Sweet, I hope it works for you this time around!

So far so good. Magisk detected proper root and passed safetynet, allowing Snapchat to login. So I'm golden. Thanks again for the rest of the steps, etc.! Have a good one!

Glad it worked for you. Would you mind posting your steps on how to get it working. I have been having issues with Magisk passing the safety check. I have flashed to 100% stock as well. I'm also using Pure Nexus if there is something different I have to do since I'm running that. Thanks!
Edit: I have followed the steps listed above after flashing Pure Nexus and it still will not pass safety check.

Are you referring to "fastboot --set-active" a(or b) CMD. Run just fastboot and you'll see the available commands. After switching slots reboot bootloader to assure that you are in the opposite slot.
There's more commands available with fastboot oem... To see those (in Linux, i don't use Windows) pull your aboot.img and run "strings aboot.img | grep oem

Basically, the gist of what I did after I gave up and accepted the fact that I'd have to go back to 100% stock and rebuild my setup again:
1) Flash to 100% stock using Flash-All.bat from the Factory Image (using ADB/Fastboot tools)
2) Boot into the OS
3) Next I enabled developer options, allowed USB debugging and allowed for the bootloader to be unlocked
4) Plugged the phone into the PC, accepted the ADB fingerprint
5) Opened the platform-tools directory in my command window
6) Rebooted to the bootloader via 'adb reboot bootloader' command
7) Booted to TWRP using the 'fastboot boot *insert TWRP image name*' command (I used one of the alpha versions)
8) First thing I did in "Temp TWRP" was I flashed TWRP RC2 permanently and rebooted back to recovery
9) I then installed Magisk v11.6 (I did not have to do any of the additional steps to fix any bootloops with changing the boot slot, etc....might be a 7.1.2 thing vs 7.1.1, etc.)
10) *Optional* I flashed ElementalX 1.09 for Pixel
11) Wiped cache/dalvik (cache doesn't seem to wipe because it can't find /cache?)
12) Rebooted to system
13) In the Magisk Manager app, go to Settings and make sure "Enable BusyBox" and "Magisk Hide" are enabled.
14) Run the SafetNet check. It should pass.
DO NOT UPDATE TO v12.0 as I guess it's not ready for Pixel's yet.

Nexus 5X bricked trying to root via TWRP (SuperSu)

Hi,
Googled a while and looked around in the forum but did not find anyone with the exact same issue as me so here goes.
Maybe someone could tell me where exactly I am doing wrong.
I have a LG Nexus 5X, latest Oreo 8.1 official update.
I want to install a custom kernel to improve performance and/or battery life.
Never rooted or anything like that so I googled around to know what to do.
So I unlocked the bootloader and flashed the latest TWRP custom recovery (v3.2.1-0).
The first strange thing unlike what I kept reading in tutorials and forums is that, although I did reboot directly into recovery after flashing TWRP, and completed flashing TWRP using its interface, I was never able to reboot into TWRP unless I flashed it again. As if TWRP could not avoid being overridden by the stock recovery. So to get back to TWRP I always have to:
reboot into the bootloader: adb reboot bootloader
flash TWRP: flash recovery twrp-3.2.1-0-bullhead.img
reboot bootloader: fastboot reboot
immediately start into to bootloader (power + vol down)
choose 'Recovery Mode' from there
Which seemed odd, that TWRP wouldn't 'stick', although I was not root yet.
Which gets me to the second part. All I wanted was to root my phone.
So after not finding a consistent way to do it - it seemed every website I visited gave me slightly different instructions to do so, I took the chance and did the following:
download latest SuperSU flashable zip file (v2.82) and copy it to internal storage
go through the process I describe in the list above to get into TWRP
install SuperSU zip file (via Install TWRP option, logs seemed ok, warned me it would take a while to boot again)
reboot, wait until it boots
But the phone got stuck in the boot screen - OS does not start to load - for at least half an hour.
Luckily, probably because the OS did not load, TWRP was not overridden and so I have access to it.
My main problem at this point is that, as a newbie on this, I am not sure what can I do in TWRP to try to restore the OS.
I have tried to restore a Nandroid backup I performed before all this, and also tried to Wipe Data / Cache and Dalvik.
Both did not work - OS still won't load.
What can I do at this point? Wipe System partition? Wouldn't that delete my Nandroid backup?
Maybe 'sideload' (not sure if the right term) an official google image for my Nexus?
Sorry again if questions like this can be easily found around the forum, but from the threads I checked I did not bump into the exact same scenario...
Thank you in advance

So in the meantime I have wiped system partition, no success either.
Ended up restoring my Nandroid backup and sideloading the latest OTA from Google, which successfully restored my phone.
Of course TWRP was overridden once again.
So back to the start: can anybody help me out on the best way to permanently flash TWRP and root the phone?
Thanks!

Forget SuperSU - Use Magisk to root your phone. As for TWRP getting overwritten - any time you take an update from Google, it will generally (if not always) restore the stock recovery. The way to get around that is to download the entire current update from Google and then use fastboot to flash the individual parts (system.img / boot.img / radio.img / vendor.img)

Well yes, the last time I expected TWRP to be gone since I have applied the whole image, and I wouldn't expect otherwise. My problem is that TWRP is always getting overridden each time I reboot my phone. Do you have any idea why?
Regarding Magisk, I will look around to see how to use it. Could you point me in the right direction?
Also I think I read somewhere that the kernel I wanted to flash in the end - Franco's Kernel - required SuperSU and did not work with Magisk. Am I wrong?

Just curious you are using "fastboot flash recovery ....." and not "fastboot boot recovery...."? The "boot" method doesn't do the install.
As for Magisk. There is a whole forum dedicated to it - https://forum.xda-developers.com/apps/magisk - Short story install the latest stable version (16.0) and call it good. I haven't had any issues with recent kernel builds including Franco, EX, etc.... One thing to keep in mind is that Magisk always gets flashed after the kernel install as it does some patching of the boot.img as part of its process.

Yes, flash, not boot.
Thanks a bunch for all your help. I didn't meant to be lazy to start by reading sticked topics, but it's so much new information for a newbie that I didn't exactly know where to start. Thanks again for sharing the links.

I'm not sure if you got this fixed. But if not, first fastboot boot twrp. Then flash supersu or magisk. Then boot back into the bootloader from twrp and fastboot flash twrp. That'll solve the problem.

I tried that but I'm getting no luck with SuperSU, always gets me in a bootloop (actually, technically not a loop since it remains Frozen with the Google logo)
I'll give magisk a try and come back with feedback. Maybe it has something to do SuperSU incompatibility with Oreo 8.1..

V2.82 Stable, not Service Release. Is the last stable not compatible with Oreo? Official website is not specific about it, so I just assumed it was ok.

3 or 5 work on Oreo. I'm not sure about stable. I don't use it.

SR5 worked like a charm. I just wish there was a compatibility matrix somewhere in their website to avoid so many forum threads and misinformation on the subject and avoid all the hustle. The whole process is dead simple but it took me days and tailored help from you guys to figure this one out.
Thanks again to all of you for your assistance.

i had that issue with a nex 6 and flashing supersu fixed it. when i got a 6p i tried the same and get stuck on the boot logo and had to sideload factory firmware to get back to go. i have a 5x on the way maybe i will try magisk.

so after i flash twrp reboot the bootloader, i open twrp and flash supersu sr5 and all is well, no more disappearing act for twrp and no more stuck on the "google"?

Same issue. So how would we go about flashing properly?

Search for recovery.img and boot.img in stock rom and flash in fastboot mode.

We would need further details on which device (region) which MIUI version (number, android, region) you were on when you attempted to install Magisk. Of course we assume here you had unlocked your bootloader first, otherwise any attempt to flash anything will result in bootloop.
Many have successfully rooted on Android 9 regardless of MIUI version.
Complication often comes with Chineses devices from what I read, Global not so much so if you are on Global device consider yourself lucky
Easiest root is probably to flash LR team TWRP If you can still access fastboot mode (voloume - + power) version 09.24 or 11.04 if you are on Android 9 or version 12.10 if you are on Android 10. Note that you probably have more chances of success being on Android 9.
And use the root feature from WITHIN that TWRP to install root on your device.
You have a complete guide of the steps to reproduce here:
Guide
I have tested on Android 9, EEA device, EEA rom MIUI 11.0.2.0 and it works without an issue if you follow the guide provided above.
If you still want to manually flash Magisk from any other recovery, make sure to use version 19.04 which seems to have the higher odds of success (update afterward from Manager).
Also as mentioned by @wang1chung do not forget to close avb 2.0.
Myself I also had RM Force encrypt option used (just in case) even if not mentionned in the thread.
But unlike what was suggested in those threads I did not wipe data.
That said since I do not want to have TWRP to stick for now, I actually want it to automatically be replaced by stock recovery all went fine for me, and Magisk is there.
And when I need TWRP for something I just flash it again and do my stuff.
Hope this helps.
Good luck!

Same problem here. Luckly fastboot was still working (vol down + power after Redmi logo gets off). Then, I've downloaded stock ROM, and tryied manually execute fastboot commands, without success. Then, I've found a .bat file inside the root folder of the stock ROM .tar.gz archive, then executed the .bat file. Phone is working back. So, whats the catch about install Magisk? Any tips?

Personally I used the hassle-free method pressing the button to root directly from within the LR-TWRP (09.24, or 11.04 on Android 9 MIUI), swiped, then pressed that other provided button to close AVB 2.0, swiped and it worked on first attempt.
Of course TWRP got replaced on first reboot by system recovery, but I dont care as I do not want it to stick on my device. I just flash it again when I need it.
Magisk stayed, updated it from Manager (well manager updated first to that new ugly theme.... yurk!), then Magisk updated, no problem.
Note that I am on EU Phone running EEA MIUI 11.0.2.0. You might get a different outcome with other devices/roms.
Side note, LR-TWRP 09.24 installs Magisk 19.04 which has been reported numerous time to work on most Android 9 MIUI regional versions. LR-TWRP 11.04 howevers installs Magisk 20.0 fyi.
Hope this helps,
Regards,

regarding the thread title, i had the same problem. right when i was about to retart everything all over from 0, i was glad i was able to just go into twrp and just unroot. rebooted and it started as if nothing hsppended. now i jjust gotta find which module made me bootloop.

try this n give us the result

Magisk version

I'm currently on Magisk 20.4
Is it safe to update to 21.4?
I heard some updates didn't go well on our phone.
Thanks

Yup, did both updates this morning. Working fine on 21.4

Quick question - I was going to do this myself to provide another datapoint, but I'm wondering about the "Preserve AVB 2.0/dm-verity" option. It's unchecked, which I think is correct... but what does this mean, and how should we have this set (ie, if we think for ourselves, what's this about?)

For some reason, the "Direct Install" (or whatever it's called) option in Magisk Manager didn't work. It just said "download complete" and didn't actually install it. Maybe that's why you heard that the update didn't go well. I had to do the "Download zip only" option, instead, reboot into recovery and install it there. It seems to be working fine. It's just the update option in Magisk Manager that didn't.

Weird, direct install has always worked for me. Other devices not so much, but always on the V30.

Sorry to repost, but for you guys who did the Magisk install, can you please answer this question? Do we leave this preserve option unchecked (that's how it's coming up on my phone).

Anyone would know better than me, but I've done it checked and unchecked without issue. I lean toward checking it when updating, not really sure why.

Yeah, it's always worked for me, as well. This was the first time that it didn't, which is why I mentioned that it could be an issue with this particular version.

I didn't get a "preserve" option (or any options). Maybe that's only if you're coming from certain versions, like 20.x versions, since I believe that I updated from 21.0.

Nope, it's there on mine when I upgraded from 21.X to 21.X. It's right there when you expand Option when you start the Install process.

I get no such option when I install it from recovery. Maybe it's only if you install it through Magisk Manager.

Well, I went ahead and installed it with the option unchecked. It applied and booted with no issues. Looks like it worked.
I figured leaving it unchecked makes sense, since I believe we disable dm-verity during the WTF process anyway, so we shouldn't need to touch it. I wanted to be sure before I did it myself, but it seems I didn't have to worry. Unchecked worked for me.

I know, and I did the opposite. I was just speaking it out loud for the sake of discussion.
Speaking of things that should've been clear earlier, it's occurred to me that that "Preserve AVB 2.0/dm-verity" probably does exactly what it says. Remember that, until about a year ago, it was recommended to flash a "dm-verity" zip in recovery when installing a ROM. I don't remember the order, but it could've been that we were supposed to flash Magisk first and then dm-verity because Magisk erased the latter. That "preserve" option, therefore, likely allows you to flash Magisk without erasing dm-verity and having to go into recovery after to re-flash it. Now, we haven't needed to flash dm-verity for a year, so the option may not matter if you're using a ROM version that's less than a year old, though there's probably no harm in being safe and checking it. Anyways, that's my guess.

My attempt of update Magisk from 21.4 to 22.0 brought me completely forgotten fastboot screen. Phone no longer boots. Just fastboot screen.
Magisk's direct install seemed to do nothing for unknown reason. Later I needed to reboot and was surprised to see fastboot screen.
Which partition should I flash using fastboot to fix this (especially preserving data, root, twrp etc.) ?
boot or boot + system? I do have a TWRP backups of these, but they are in WIN format. Can Ijust flash them with fastboot?

There's more to this -
fastboot devices
list no devices.
Reinstallation of the LG drivers didn't help.

You need to flash the original boot image from your stock or custom ROM via the flash boot using the command "flashboot flash boot <boot_file>
Then reflash TWRP and re-install magisk. Maybe the v21.4. The latest one broke my boot too. Good luck!

I've got TWRP flashable TWRP-H93030b_00_OPEN_EU_0704.zip with two files: boot.img, and boot-original.img.
If I recall correctly boot.img is pre-patched? Which of these should I use?
I finally managed to connect over fastboot.

boot.img should be good. You can always flash the other boot image if it does not boot up.

Managed to flash "boot.img", TWRP and boot to TWRP, but... got "Mount Decrypt Data Enter Password".
I haven't encrypted purposely any partition.
Furthermore TWRP locked and doesn't unlock when I try to "swipe to unlock"...

Forced reboot. Android started. Phone works, but Magisk isn't installed. Rebooted once again into TWRP and installed Magisk ignoring data decrypt message. TWRP said it failed, but after reboot Magisk Manager sees Magisk installed and so TitaniumBackup
Seems it solved the prolem.
