Hi guys, Android 10 update is out now. Maybe this time this trick will work just like the Mi A1 ? Can anyone confirm it please.

No. I tried today. All it does is showing the bootloader unlock screen to select weather or not to unlock.

I have a Motorola lapdock, I was just wondering if I could get a Nexus 5, and just use it as a laptop via the slimport adapter.
[Nexus 5 Q&A, Help & Troubleshooting] digitalsonar:
Well, you can mirror the screen to any hdmi port with a miracast dongle. And you can connect a bluetooth keyboard and mouse. I'd post the relevant links but apparently new users aren't allowed to post external links.

1. buy a nexus 5

2. buy a miracast dongle

3. install ubuntu touch - very easy with the ubports installer

4. enable screen mirroring

5. connect bluetooth mouse and keyboard

---------- Post added at 11:29 PM ---------- Previous post was at 10:58 PM ----------

If you search the instructables site there's a guide on connecting a rasp pi to the lapdock. I suppose, in theory, any device with hdmi and usb ports could be connected with the proper adapters. But I can't imagine using android as a desktop environment. I'd be interested to find out how the "rasp pi zero w" works with the lapdock. Dirt cheap and has all the necessary ports with wifi/bluetooth.

came out today. bricked my lg v20 h918

come up showing red text with number of times bootloader is unlocked and will not boot further..

tried direct install.

had to hold button down like going into recovery then select yes twice then getg into twrp then restore boot and lafs etc.

then when all working i tried to install the same version via twrp install same issue. apparently installing to wrong partition..

reinstalling the older 20.1 (hopefully you have it downloaded) from twrp worked fine.

I was able to get up and running again by flashing H91820h.zip in TWRP, then flash Magisk-v20.1.zip and finally TWRP 3.3.1-0 2019-05-17 .img

Phone booted normally after this process. Hope this helps!

Similar situation. Fortunately, I did a nandroid backup first, so I restored it to get the phone up and running again.
[LG V20 Guides, News, & Discussion] James.ptrsn:
My Success Story

For those of you who, like me, didn't have a known good backup to work with, here's what I did:

Determine ROM version installed if you don't know what it is (I was able to check the /system/build.prop file from TWRP under ro.lge.swversion)

Grab the appropriate ROM .zip file (I got my h910-10r zip file from the H910 Root Post)

Unzip the ROM file

Grab the "boot" file from the ROM and place on an SD card as boot.img

Flash boot.img to the boot partition using the TWRP install function (you'll have to toggle it to show Images in the install screen)

Reflash Magisk v20.1 (you can download it from github)

Wipe Dalvik and Cache

Reboot

Wait for the LONG boot process which will go through the nerve-wracking android is staring screen with the percentage bar as it rebuilds the Dalvik cache (I think that's what it's doing)

As a note, this did not clear any of my data.

Good luck, YMMV.

Unfortunately i wasn't lucky with this.. got stuck in fastboot, my sd and internal storage are both wiped, Rip years of data on that sd.. Can't get a system on the SD or internal storage, Fastboot isn't helping, ADB sideload won't load in twrp, LG Bridge won't detect my phone Am i screwed with this? I can boot to twrp but thats about it
[LG V20 Guides, News, & Discussion] omega552003:
TWRP on my US996 automatically made the phone a usb drive when it got plugged in. Have you looked for it as a usb drive? also have you checked your usb drivers?
[LG V20 Guides, News, & Discussion] pendgy:
Fortunately there is even more easy way to recover. :D

My H990DS has been also affected by Magisk update. Luckily I discovered that Magisk itself makes a backup of the boot image during update from previous Magisk version. It is located in the /data/magisk_backup_<very long sequence of characters and digits>. The name of the backup archive file is boot.img.gz

So I booted to TWRP, unziped the file boot.img from the above archive and flashed it to the boot partition using TWRP. Then rebooted to system.

And that's all folks! No data loss, no need to look for original ROM.zip, no need to look for and re-flash Magisk 20.1 (the system has been restored automatically to Magisk 20.1), no need to wipe Dalvik and Cache!

I think that this solution is the most simple and easy, so need to be in sticky post.
[LG V20 Guides, News, & Discussion] majhau:
I'm in the TWRP Recovery file manager and I can't see magisk backup folder.
[LG V20 Guides, News, & Discussion] fatappel:
Thank you. This helped a lot. Can't remember ever being without my phone for this long. Very stressful. This worked for my LG V20. Few things to add. I was super nervous to boot into twrp using the hardware "factory reset" option. Normally it just asks to wipe data once before booting into TWRP but after this happened, it asked two times. Was worried the magisk "update" wiped out my twrp and I was going to actually wipe all of my data using the recovery option. After unsuccessfully trying multiple ways to install twrp via fastboot as a safety net, I bit the bullet and did the double factory reset. Thankfully, it brought me to TWRP. Those of you worried, hope this helps ease your mind that twrp is intact after this debacle.

Next, using [MENTION=5429267]pendgy[/MENTION] help, I found the boot.img.gz but was unable to unzip in twrp. I copied the file to the internal sd so I could view on my pc. Connected to pc while in twrp and unzipped the boot.img.gz folder. Then extracted the boot.img into the internal sd. Was then able to install image to boot partition. Rebooted and everything was exactly as it was 17 hours ago when my heart sank. Yay!
[LG V20 Guides, News, & Discussion] Snakecharmed:
Thanks to everyone for the reports and warnings. I saw the update to Magisk Manager yesterday on my Shield K1 and allowed that to update. I didn't update Magisk itself because I don't trust the direct install method through Manager. I saw the notification on my sandbox V20 this morning and dismissed it. My daily V20 hasn't received an update notification yet, but I think I disabled status bar notifications for Magisk on my daily. I'll be sure to not install 20.2 on either phone.

Magisk Manager's update notifications are pretty annoying to be honest. My devices are already rooted. An updated version of Magisk isn't going to make them rooted better.
[LG V20 Guides, News, & Discussion] Khiraji:
Oh boy. Learning a lot of hard lessons this morning.

Apparently my TWRP install has been broken/corrupted for who knows how long. I'm now several hours into restoring my phone from basically scratch (had to retry a bunch of times because I'm a dumbdumb and haven't poked around at Android recoveries in ages).

Moral of the story: BACK UP EARLY and BACK UP OFTEN. If you don't have a backup (any kind of backup), the day will inevitably come when you wish you did. Sigh.

Oh well, maybe my phone will run a bit smoother now. Good luck everyone.
[LG V20 Guides, News, & Discussion] Attila17:
How did you unzip the archive with TWRP?

Edit: Nevermind, copied the archive to external SD und unzipped it with 7z on my computer.
[LG V20 Guides, News, & Discussion] pendgy:
In fact I did the same :) I didn't menioned all the stuff with connecting to PC, copying files to PC, extracting archives and copying back to the phone the boot.img file for subsequent flashing via TWRP. This is because I know the forum members here are experienced guys :)

The lesson learned is that TWRP is rock solid and we shall trust to it :)

Sorry, didn't see your last post in time. Just thought that you did it with TWRP, so there had to be a way. :silly:

Thanks for your help!
[LG V20 Guides, News, & Discussion] pendgy:
If you had TWRP installed you

shall not try

to install it again. TWRP is very stable and protected, so it survived the buggy Magisk update. Just do the following:

1. Power-off the phone. That is the beauty of our V20s - you can do this even when stuck in fastboot screen, just remove the battery :)

2. Put back the battery

3. Press Volume-down button and while keeping it pressed press and hold the power button.

4. Wait untill LG logo appears on screen. Release the power button for a moment while still keeping Volume Down pressed and press te power button again (Volume Down should be hold pressed all the time).

5. You will see the Factory Reset Menu. If you have TWRP installed you may answer with "yes" on both subsequent questions and will end up with TWRP main menu. If you have not TWRP installed, answering both "yes" will reset your phone to factory defaults.

It's a gzip file, not a Windows zip. To unzip, use the gzip command with the -d (decompress) option on the phone

gzip -d boot.img.gz

Big thanks to pendgy for the quick solution! I had that awful feeling in the pit of my stomach after the phone rebooted to the bootloader screen, but after some coffee, I found his solution and it was a quick fix.

FYI this was on an LG V20 US996
[LG V20 Guides, News, & Discussion] escueto33:
Hello, how do you unzip the file? is it possible from TWRP?

Thank you
[LG V20 Guides, News, & Discussion] pendgy:
No, it is not possible to unzip from TWRP. I've connected the phone to my PC, transferred .gz file, unziped it, and transferred back the unziped boot.img to phone (in particular to the MicroSD card). Then flashed it to boot partition using TWRP.

EDIT: See the above post by [MENTION=4584245]solo2racer[/MENTION]. It is possible from TWRP also.
[LG V20 Guides, News, & Discussion] bamboozed:
Well I should have checked the forums before updating Magisk on my H918 this morning. Unfortunately I did not.

After updating, I had the same issue as the rest of you guys. However, even after using TWRP to install the boot.img from the Magisk Backup it still takes me to the fastboot screen.

Any ideas of what I should do next (trying to avoid finding the original rom, losing data, etc).

Here is what I did after the Magisk update:

* Uninstalled Magisk using the uninstaller via TWRP (from XDA forum)

* ReInstalled Latest Magisk (just thought something went wrong with the original update)

* Created a TWRP backup just in case something got worse (other update is 2 years prior)

* Tried to flash boot.img as direct in post #13 of this thread
[LG V20 Guides, News, & Discussion] pendgy:
I think you did wrong performing first 3 bullets above. Yes, I know and I understand how terrible is the feeling when your phone stuck in fastboot. I was in the same situation. But managed to keep calm, read the forums and performed any actions only after careful study. The right reaction of the case shall be to perform te bullet No.4 immediately after failed magisk update.

It think you may survive if you find the original ROM boot.img. Flash it via TWRP and immediately after that flash the Magisk 20.1

WITHOUT REBOOTING

between these two actions.
[LG V20 Guides, News, & Discussion] bamboozed:
Oh I agree that my knee-jerk reaction was likely the incorrect thing to do.

Just to verify, I should do the following steps:

Flash Magisk boot.img to boot

Flash original rom boot.img to boot

Reboot

No clearing of Dalvik?

I'll give this a shot and report back. Time to go find that rom. Thank you for the prompt response

Edit: My post history says my rom is 20g-prerooted (https://xdaforums.com/showpost.php?p=79164023&postcount=529)
[LG V20 Guides, News, & Discussion] pendgy:
No, no, no! The "normal" procedure is just to flash boot.img from Magisk backup and then reboot. This should work if you just updated Magisk 20.1 to 20.2 and stuck in fastboot.

But you already did some wrong things (uninastalled Magisk, intalled it again, etc.). So now you should choose the longer route. Now you should flash the original boot.img from your original ROM. It could be a challenge to find it. Then you should flash Magisk 20.1. You shall not reboot between flashing boot.img and flashing Magisk.

Before going to longer route you may try again the first option.
[LG V20 Guides, News, & Discussion] bamboozed:
Ah, I misunderstood you.

Tried the shorter route again just to ensure, and its a no go.

So I just need to follow this process (https://xdaforums.com/showpost.php?p=81372967&postcount=8)

So just flash the rom boot.img, then magisk 20.1, and I should have all my previous data still? If so, the next step is a fresh backup :D
[LG V20 Guides, News, & Discussion] pendgy:
Yes, follow the process in https://xdaforums.com/showpost.php?p=81372967&postcount=8

[LG V20 Guides, News, & Discussion] jjcf89:
I got a little stuck here, so I'm going to take your method and break it down into steps. Hope you don't mind.

Note: I couldn't find the /data/magisk.... folder from the usb mounted drive so used TWRP file manager

Using a PC:

Boot into TWRP. https://xdaforums.com/showpost.php?p=81381337&postcount=22

Goto Mount and Make sure Data and Micro SD card are checked

Go home and goto Advanced -> File Manager

Navigate to /data/magisk_backup_<long string>/ and click boot.img.gz

Copy File to /external_sd (sd card location)

Go home and goto Mount

Select Enable MTP

On computer, find boot.img.gz file on Micro SD card and extract it to desktop. I used PeaZIP but 7zip or Winrar should work too.

On computer, copy extracted boot.img back to Micro SD card.

Disable MTP

Go home and goto Install

Select Install Image in bottom right to switch to looking for .img files

Navigate to boot.img file on /external_sd and click on it

Select Boot partition and swipe to flash

Reboot System

Click Do Not Install, to avoid installing the TWRP app

Using Terminal in TWRP

After going through this, I noticed a shortcut that wouldn't require a PC if your comfortable using a terminal.

Thanks to [MENTION=4584245]solo2racer[/MENTION]

Boot into TWRP. https://xdaforums.com/showpost.php?p=81381337&postcount=22

Goto Mount

Make sure Data is checked

Go home and goto Advanced -> Terminal

Type cd /data/magisk and hit the Tab button in top left of software keyboard. This should auto-fill the whole magisk path. Then press the checkmark button on the keyboard.

Type ls and press the checkmark button to see the contents of the directory which should contain the boot.img.gz file

Type gzip -d boot.img.gz and press the checkmark button.

Type ls and press the checkmark button to see the contents of the directory which should now contain the boot.img file

Go home and goto Install

Select Install Image in bottom right to switch to looking for .img files

Navigate to boot.img file at /data/magisk_.../ and click on it

Select Boot partition and swipe to flash

Reboot System

Click Do Not Install, to avoid installing the TWRP app

To reiterate, if you don't have a magisk boot.img.gz backup, you can follow the steps on post #8. https://xdaforums.com/showpost.php?p=81372967&postcount=8

Same on my Zenfone 2 (ze551ml) it would boot and lock up, Then reboot and lock up over and over. I just went into recovery used the magisk uninstaller and installed 20.1 again. Seems to be working fine with the 7.5 manager but the 20.2 update kills it.

[LG V20 Guides, News, & Discussion] Snakecharmed:
Agreed. Turn off the update notifications. There really isn't a good reason to blindly chase the latest Magisk update. The vast majority of the time, there will no improvement to your user experience, and even then, those improvements are more likely to happen in Magisk Manager than Magisk. The way 20.2 nuked so many installations across so many phone makes and models has been brutal.
[LG V20 Guides, News, & Discussion] pendgy:
Thank you for doing that! You may add that issue affected a variety of LG models with varieties of ROMs (at least I've spotted LG-G5, LG-G6, LG-V20-all variants) and maybe some other brands also. There at least 5 threads in the forum - in LG sub-forums and in Magisk sub-forum. I hope the developers will take care about as this is not a single-failure issue affecting only a particular ROM and phone configuration.

And thank you also for your post#39 describing my method in steps.
