OK, with testing I found a solution for the problem
Here the steps what i've done:
1. Load the Flyer with the power supply unit.
2. From PC Commandpromt. Start fastboot flash recovery recovery.img. I've get the message "waiting for devices". I've used a old CWM 4 reciovery Image
3. Now connect the Flyer and Start with "Power + Down". Here was the surprise that now the Bootloop stops and i see now the Boot Menu. So I change here to fastboot and flash the recovery Image new.
4 Rebbot now an voila bo boot more and I can use the normal cwm recovery mechanism to recovery one of my old images... Perfekt

Install Quick Boot (Reboot) and reboot to recovery. Or you can install Android Terminal Emulator and type the following code:
Code:
su
reboot recovery
Hi, I'm trying to get root access to my phone, and have installed ADB and everything, and it's all working, but when i try and boot my phone in recovery it just reboots it normally.
That command doesn't work for every phone. Is it an LG?
No it's a sony xperia z3 compact
Have you tried the common android vol+ (sometimes vol-) and pwr buttons combination to get into the boot menu that lets you choose recovery?

hey, i've got a problem.
i'm running on Oreo 20r and installed Magisk using TWRP.
after rebooting, my device stucks in a bootloop.
is there any solution for my problem?
flashed magisk 17?
yes...
okay, actually I am currently stucked with the same issue too.
But I just got back my TWRP by doing following :
1) Boot into download mode (https://www.youtube.com/watch?v=_mycJDiFUPk)
2) Still in download mode, press and hold "vol down + power" (this time USB cable is still connected to PC and phone), it will reboot the phone, hold both button till you get in fastboot mode
3) once in fastboot mode, flash back TWRP as per unlocking guide
Now I am still in TWRP, hesitating what to do next. lol
Hope it helps a bit
it's not possible for me.
my device reacts to nothing... no keys, no recovery, no download mode
bootlooping like no tomorrow
maybe you can install KDZ-file using LGUP
or try to flash ZIP-file

I just clean flashed back Boombox 1.3 with magisk 16.0, so far booting up good.
I think you need to try again.
The download mode is a bit tricky, need to very fast hold long power button till off, once off, hold the vol up and connect the USB cable to PC. it should trigger the download mode
The bootloop that you have now, is just "LG V30 ThinQ" and the "unlocked bootloader" msg right? same as me I think

okay, let me try describe my steps in details :
1) Phone is bootlooping, USB cable is connected to Phone, NOT to PC
2) Hold down power button only till the screen becomes "black"
3) Once "black", quickly hold the "vol UP" and connect the USB cable to the PC
4) Now it should show the "download mode"
5) Without removing the USB cable, hold "power + vol DOWN"
6) Once screen becomes "black", release the "power" button, hold the "vol DOWN"
7) Until you see the "fastboot mode"
8) Now you can flash TWRP back using fastboot command from the PC
9) Boot back to TWRP
p/s : yes, the phone cannot be turned off, for long time, but it can be for a very short time. Need to use that short time to trigger all the keys
I have the same problem after flashing Magisk 17. I am in a bootloop between LG black start and root/unlocked bootloader warning screen.
I followed your steps 1-7 in a command line screen (as administrator) and it works but it seems that recovery flash is not working because the command line screen show me a very short time in the recovery flashing work (see attached image).
"fastboot reboot" returns me to the bootloop.
"Power Off" and "Restart" options in the phone returns to me to the bootloop again.
If I unplug the USB cable in the fastboot screen, the phone goes to the splash black screen and does nothing.
WTF!!! it's working.
i tried it one more time like you described it.
think i did it too slow before. booted into TWRP and the rest will be no problem (i hope so).
thank you sooo much!

use this description to enter download mode and flash TWRP using fastboot.
but after you flashed TWRP, you have to boot into TWRP via fastboot using this command fastboot boot TWRP-3.2.1-joan-v0.1.img
1) Phone is bootlooping, USB cable is connected to Phone, NOT to PC
2) Hold down power button only till the screen becomes "black"
3) Once "black", quickly hold the "vol UP" and connect the USB cable to the PC

how did you reflash Magisk 16 after?
@ChazzMatt HAve you looked at this? Some of are having issues after Magisk updated the Magisk app and then lost root...I guess we shouldnt have flashed 17, but when I try and reflash 16 I get the "updater process error" does that mean my only option is to format SD again, or do I have to start from scratch?

No, see the last few posts of WTF thread. You just have to uninstall 16 first.
Guys I have a huge problem.....
I uninstalled magical 16 using the official uninstaller.....the device went into a bootloop I was able to boot to recovery but the data is now decrypted.....so tried to use OTG to restore a android backup and now I have a "the backup may not boot unless you change back to ext4"
I am at my wits end kindly help
Edit: came out of it. Thanks

I am stuck with the same kinda issue. By mistake restarted the Phone after wiping the phone for a fresh rom install. now i can see only the LG boot logo. There is no way to power off the phone. Pressed the power button alone for couple of minute but no use. Tried pressing the Vol Down and power to restart. I get a 1 sec window when the phone is off between the restarts but your method does not work in that short time. Is there a way to power off the phone ?
basically there is no Rom on it and does not detect on the PC when plugged in
Please help if you know anything

Try going to TWRP
1. hold vol down + power till it off
2. Once it shows the first on screen, release the power button and press back the power button (vol down hold)
3. A menu for factory reset will be shown, agree to it 2 times
4. Then it will boot to TWRP ( no data will be deleted )

Hi,
I tried to flash lineageos 16 on my bkl09 emui9.
It was working but it was impossible to install app by play store... I tried many times to re-flash lineage img.
I'm actually blocked on TWRP. But it doesn't launch. When i start my phone, it boots on twrp, and the phone stays on the twrp boot screen but doesn't launch.
I can't turn the phone into fastboot mod by pressing vol- and power . It just restarts and reboot recovery twrp and block on boot screen twrp without launching...
I plug my phone on my computer, it reconized as adb devices but when I try to turn into fastboot mode by adb, nothing happen...
I hope there's a solution !
(and sorry for my english ... :/
power off the phone, put USB port in phone, press volume down key, now connect USB port to PC with volume down key press. it should boot to fastboot.

hi. Please, help, i cant reboot to fsstboot. If i do this from app or from adb my phone just reboots twice. I can boot into recovery and into download mode
Don't reboot into fastboot, boot into fastboot.
1st hold the up and down and power to start up so that it shows more than that "...is now booting". Then power off and press "down" and "power" with USB plugged to enter fastbboot. In fastbbot, flash the userdata.img and the cache.img (This cleans data and cache totally) from Huawei's updates, then you will be able to get into TWRP without being stucked.
