Bootloop issue

Hi,
maybe anyone can help me getting out of the bootloop(LG G6 H870)? reason, why I'm stuck in bootloop: I installed magisk v13.0 (beta) and magisk manager 5.0.3 after unlocking my bootloader to gain root access. A new version came out and I decided to installed it because it switched magisk 13 from beta to stable. I opened magisk manager, updated the manager, downloaded magisk v13.2 and flashed it through recovery (twrp). But i wasn't able to get root access (rebooted a few times, but no difference). So my next plan was to uninstall magisk using the magisk-uninstaller.zip and flashed it using twrp. After this step, my phone rebooted over and over again. The only thing i can do is to get into the factory data reset screen. While booting , i connected my phone to my laptop, but obviously its not recognized so I can't execute any adb commands.
Any suggestions how to access recovery mode or how i can leave the bootloop?
Thanks
edit:
I managed to solve my issue in following way:
1. booted into download mode like Killua96 suggested while connected to my computer
2. opened lgup on and flashed the factory image
3. rebooted into bootloader and flashed twrp image
4. copied my backup (which i made with twrp) into the BACKUP folder
5. restored my backup with twrp
6. after reboot I wasn't able to unlock my phone, because my correct unlock pattern wasn't accepted
7. booted again into twrp, navigated into /data/system and deleted locksettings.db-wall, locksettings.db-shm and locksettings.db
8. rebooted one more time and everything was fine again!

Try to connect it to the pc while bootlooping, then turn it off by keeping pressed power and vol- when the display turns off quickly keep pressed vol+ and it should boot in download mode... Good luck

Ok, I'm able to access the download mode now. I only have access to a laptop running Linux right now, when I'm back home, I try to flash the stock ROM using the official LG Tools! Thanks for your help!

Sprint S6E+ and Twrp Issues

I'm hoping someone can help as I a seem stuck trying to reinstall Twrp on my Spring S6Edge Plus G928P phone. I previously did have twrp installed but needed to reinstall stock nougat after a failed lineage os install attempt.
After each attempt to install twrp with Odin and attempt to access recovery I get a blank/dark screen, and no default or twrp recovery screens.
As far I know I have done everything correct.
11. Have developer mode turned on and OEM Unlock and Usb debugging turned on.
2. Press Vol-Down, Home, and Power to access to download mode.
3. With odin, installing the latest twrp for Sprint; twrp-3.2.3-0-zeroltespr.img.tar
4. I have auto reboot turned off in Odin when flashing the twrp file.
5. After the successful flash, I then unplug from USB. hold Vol-down, Home, Power till it turns off, then immediately over to Vol-Up, Home, Power.
And then just on a black screen.
I am then forced to enter download mode again via Vol-Down, Home, Power and with Odin reinstall the stock image.
Is there something I'm missing?

Finally had success tonight. I'm not sure why but I think maybe there is an issue with installing the latest twrp version 3.2.3 directly.
I had success getting twrp 3.0.2 installed after first using CFAR and the twrp app. After that again with the twrp app was able to get the latest 3.2.3 installed.
Now hopefully I get the lineage OS installed for a test run.

Root, flash recovery and custom ROMs. Only for LG G6 H872 (20g original firmware)

This is a much easier way to flash a new recovery and custom roms. Besides using a PC / USB cable for unlocking the bootloader, all the process can be done straight from your device.
IMPORTANT: This procedure is only valid for LG G6 H872. Other G6 variants will end up bricked. All partitions will be wiped, this means that all the files needed must be saved to your external SD. It’s been tested with 20g firmware.
Prerequisites:
LG G6 device with original Oreo 20g firmware and fully charged
External SD card
Download and install su98.apk, Root Checker and Flashify
Download this specific TWRP version and save it to your external SD
Download Magisk and save it to your external SD
(Optional) Download latest TWRP to flash A10+ custom roms and save it to your external SD
0. Backup everything
1. Unlock your bootloader, otherwise you will brick your device. You can follow this guide.
2. Disable Google Play Protect (from PlayStore) or you won't be able to go on with the next step
3. Install su98.apk, open it and tap INSTALL NOW (leave the checkbox blank)
4. Install Root Checker and open it to verify that your device is rooted
5. Install Flashify and open it to flash TWRP (recovery_h872_20180813-1.img)
6. Turn off the phone (at this point, if the phone boots to Android you will have to start over from step 3).
7. Reboot into recovery (press and hold Volume Down and Power buttons together for a few seconds. When the LG logo appears, release the Power button while keep pressing the Volume Down and then press the Power button once more. Once you see a white screen, use Volume keys to choose "Yes" and Power button to select the option, you will have to press “Yes” twice).
8. Once in TWRP (be patient, takes some time to load) a “decrypt data” legend will appear. Press cancel. Then swype to allow system modifications. After that, go to Wipe / Format data and confirm by typing yes.
You are now able to flash any Stock ZIP (not KDZ). If this is your choice, remember to flash Magisk after flashing the ROM. If you want to flash any other custom ROM, jump to the next step.
9. Still in TWRP, flash Magisk to keep your device rooted
10. Flash the latest TWRP. Go to reboot options and tap Recovery
11. Once in the new TWRP, wipe system, data, dalvik, cache
12. Flash Rom + Gapps + Magisk and reboot to system

Special thanks to Man Stevo for sharing this!!

LG G6 H872 back to stock Oreo 20g
IMPORTANT: All partitions will be wiped, this means that you must backup everything otherwise you’ll lose everything stored in the phone.
Prerequisites:
LG G6 device fully charged
USB cable
LG Mobile driver installed
Patched LG UP installed in the right folder (otherwise your device will not be recognized)
LG G6 H872 latest Oreo firmware (20g)
0. Backup everything.
1. We are going to flash this using the patched LG UP. Place the files in C:\Program Files (x86)\LG Electronics\LGUP. You can't just unzip it anywhere and run it, it will not find the model file.
2. Boot to download mode (power off your Phone. Plug one end of the USB cable to PC and while holding the Volume Up button connect the other end of the cable to your device. Release the Volume button once the device boots into Download Mode. To exit the Download Mode, press and hold the Power button until the device reboots)
3. Open LG UP and wait until the device model is recognized. Then choose partition DL
4. Pick the H872 20g KDZ and click start / ok
5. You’ll now get a list of partitions to flash, check them all and click start / ok
6. You may get a warning about additional modified partitions. Ignore it, and click ok
7. When the process is finished, the device will reboot
If the progress bar reached 100% and the device got stuck in the pink bootanimation, follow these steps:
Unplug the device and turn it off by holding Volume Down + Power (keep holding them down until it turns off)
Once the device is off, press and hold Volume Down and Power buttons together for a few seconds. When the LG logo appears, release the Power button while keep pressing the Volume Down and then press the Power button once more. Once you see a white screen, use Volume keys to choose "Yes" and Power button to select the option, you will have to press “Yes” twice.
The phone will now restore factory defaults and reboot to system
IMPORTANT
In case camera crashes when opening or you get an IMS error, you'll have to flash H87211h_00_0406.kdz (same procedure as above from step 0 to 7, just changing step 4 where you need to pick H872 11h KDZ), reboot to system (until you finish the initial wizard) and then flash H87220g_00_1228.kdz (again, same procedure from step 0 to 7).

Works like a charm. Thanks
FYI, Going back to full working stock need to return to Android 7 firmware 1st (H87211h_00_0406.kdz); otherwise, you will get camera and IMS error.
Questions:
Does SkyHawk Recovery support stock firmware as TWRP can't backup and restore stock properly.

Worked here when getting back straight to stock 20g, but good to know for those with issues.
I didn't test any custom recovery to backup stock, so I don't know about that.
Thanks for reporting!

Has anyone else used this recently? I cannot get the phone to boot to recovery at step 7. I've tried:
1) press vol- and pwr until the LG logo appears, release power, and press it once more
2) same as 1) above, but pressing power button multiple times to get through the "your phone can't be checked for security stuff" warning
Both times, it just boots straight to Android.
EDIT: Using adb reboot recovery worked!

Yeah, it works @zolotiyeruki
Check the vídeo in the first post for more details with the whole procedure.

Anyone else get an antivirus warning for the su98.apk?
My AV indicates it has a trojan in it - Trojan:Script/Ulthar.A!ml

To follow up on this, I believe it's flagged because it is the exploit to get root that is seeing.
So it seems it's getting recognized by the anti-virus correctly and it's the desired functionality of the .apk.
(Anyone feel free to chime in to correct this if it's inaccurate.)

Download latest Magisk APK, rename it to ZIP and flash it through TWRP.

Bootloop after Viper4Android

So I just rooted and got everything to work just fine (.33). Thought i'd smash in Viper4Android aswell.
The phone is now stuck on the logo with the red and two white dots.
I can get it to reboot with Vol+ and power, but the power-button does not let me go into recovery mode at all. It's like its disconnected.
Is there anything you can do to get into recovery/fastboot from here?
Also tried every single vol+powercombination with 0 results..
Thanks in advance.

What viper4android version did you install? And what Android version are you on?
If using Magisk 21> you should be able to hold down power button to boot into safe mode.
Hold power button and volume down and up at the same time, this should boot you into bootloader.
If you're on Android 10:
Boot into TWRP and remove module folder from data/adb/modules
Android 11 (or 10)
[Recovery][Stock OOS]Oxygen OS Stock recovery with ADB enabled
While waiting for a working TWRP for all those needful of the possibility to access their file system from recovery, e.g. for removing an offensive magisk extension preventing boot I repackaged the Stock OOS recovery but with ADB enabled...

Thanks for the reply.
I seem to have solved it (for now..).
I could not get any key to answer to my commands when i rebooted the phone (hence why i couldnt get into recovery etc.), it only went back to the loop after displaying the usual message about the bootloader being unlocked.
Holding down both volume-buttons and using the msm-tool i managed to get it back to OEM (with everything locked. Again. Lmao) so now i just gotta watch out when I install Viper again (if i do..).
Running Oxygen 11.0.3.3.IN11BA with the latest Magisk (I just patched it today)
Edit: I just used the Viper4Android that i found inside Magisk if that makes any sense.
I'll try your links and see if i have to re-flash again..
Cheers

Magisk 21.4 causing bootloop on LG G5(H850)

Hi all,
So I was triying to update my Magisk through the recommended direct update method. I got a bootloop. Never had any issues with this update method, Magisk always did a splendid job.
Now my only options are:
1. Flash a custom rom (I don't have any stock Telekom roms)
2. Update Android OS to 8.0 with LG Bridge (my goal is to have a stock rooted android os, that's why I'm doing this)
3. adb reboot, flash the latest twrp recovery (at least that's working)
4. flash the latest Magisks without reboot option, just power off and then turn on. And this is stage where I get a bootloop.
I only have v19.3 saved on my HDD. Flashing that is working just fine, not causing any bootloop. However Fake GPS and Pokémon Go are not working with this version anymore. :/ So I'm kinda chess-mated here because of this Magisk bootloop.
Anyone can help me how can we fix this?

I have bootloops with all Magisk 21.x versions, so I'm stuck with 20.4. Can't you download Magisk 20.4 and install it from TWRP? I don't need SafetyNet, so I have no idea if Magisk 20.4 can still pass the check, but at least it would be newer than Magisk 19.3.

I downloaded the previous 21.0 versions from here https://droidfeats.com/download-magisk-zip/ flashed it and it's working. I also tested the previous versions. Seems like only 21.4 version is affected only, which is the latest stable.

I had the same problem: I had Magisk 21.4 and withing Magisk Manager I tried to update to v. 22.0 because I got an update prompt that asked me to do so. Trusting everything was fine I updated but I got a bootloop. I managed to recover from bootloop and get the latest version of Magisk working in my Huawei Y5 MYA-L13 (Android 6.0). For these steps, it is assumed Magisk v21.4 and Magisk v22.0 ZIP files are stored in your storage. This is the way I did it:
Manage to get into stock recovery mode.
This step was more time-consuming than it should have been... This Huawei model with the bootloader unlocked states at boot: "Press volume key up to 3 seconds to enter recovery to restore your device". It didn't... With Vol+ just restarted the device (no TWRP or stock recovery or download mode...) and pressing Vol- it loaded into the bootloop. It took me some time to guess the right way:
Plug the turned-off device into a USB cable plugged into the computer.
Wait for the device to start into "charging mode" (I made up this... I mean wait until the charging percentage appears).
Turn on the device using the Power Button.
Immediately, press and hold Vol+.
The device will reboot. Press and hold Vol -.
The device will get into the stock recovery mode (EMUI Huawei eRecovery).
Try again if this fails... After a few attempts, you'll get it.
Now the device will be visible to ADB. Verify this in a command prompt with adb devices. Mine was listed as 0123456789ABCDEF recovery.
Use the command adb reboot recovery to get into the real recovery mode. I mean TWRP. (It's still there even if it seemed to be it wasn't).
Flash the version that caused the problem. In my case, I had Magisk v21.4 initially, so I installed this same version ZIP I got from the official Magisk GitHub releases section.
Once finished the installation, if it was successful Reboot. The device should boot normally this time, having installed this version of Magisk and not the new one, of course.
Now proceed to uninstall Magisk 21.4 completely using the ZIP file provided in the above URL (step 4) with TWRP.
Follow the official installation guide in the Custom Recovery section to install Magisk 22.0 (that is: having renamed Magisk-v22.0.apk to Magisk-v22.0.zip previously, use TWRP to install it). Reboot.
Your device should boot normally. You'll find a Magisk app where you'll be able to verify latest Magisk 22.0 was successfully installed!!! DONE.
I hope my guide is useful to someone. If so, please like my post to be aware it was useful. Greetings!
TL;DR
adb reboot recovery
Install Magisk-v21-4.zip. This solves bootloop problem!
Uninstall Magisk using Magisk-uninstaller-20210117.zip
Rename Magisk-v22.0.apk to Magisk-v22.0.zip. Install it using TWRP.
Reboot. You have the latest Magisk version v22.0 installed with no bootloop!!!

I've upgraded from v20.4 to v22 yesterday using the new Magisk app, it all went smoothly.
