I have a LG D805 locked to Telcel in Mexico and tried to SIM unlock by unlock code.
After SIM unlock, I can't get the local mobile operator's signal and the the problem was started there.
Rooted by ioroot24 and
SuperSU, FreeGee,Titanium Backup Pro were installed
installed CWM and ROM manager and backed up files.
Then flashed D805_panama_stock.zip for testing.
Failed to get the signal. and then flashed D805_10A-724_RADIO.zip
Tried to wipe data / cache by factory hard reset.
After factory hard reset, Everything's gone and Just LG logo boot loop.
Now,
Press and hold power, then I can turn it off.
When g2 is turned off,
Press and hold Volume + button and plug in USB, then can't enter Download mode
When g2 is turned off,
Press and hold Volume - and Power at the same time until LG logo's on and release them and
Press and hold them again and then press Power buttom 3 times , then Factory Hard Reset.
again enter into LG Logo boot loop status.
When g2 is turned on,
Tried to communicate thru ADB but not listed.
When g2 is turned off,
Press and hold Volume + & - and Power button at the same time,
can get emergency mode when the touch panel doesn't work.
Tried to do it by using Ubuntu's terminal command but the problem is now that
the computer does not recognize g2.
while installed KOUSH universal ADB driver.
Is there any ways to have PC to recognize g2 ?
Thanks in advance any clues and advise to catch g2 by PC in this case.
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"

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.

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 )

help. after following this guide (Download Pixel Experience ROM on LG V30 with Android 9.0 Pie | from getdroidtips) my lgv30 is stuck un boot screen and won't do anything. i tried every combination of buttons but it only reboot always like that. i can't turn it off and i can't even reach recovery mode. from the guide i read: i installed the zip file from twrp and when it said "complete", the phone froze a bit and then it got stuck where i am. pls any help?
1-press the power button and volume down button when your phone is stuck on lg logo.
2-When its shut down, Plug the data caple in phone and press the volume down button hurry bcz the phone reboots very fast this will get u into fastboot mode.
3- Then type "fastboot boot (whatever your twrp img names). Then u will boot into twrp. Then flash a flashable zip firmware?
I had LOS running happily for sometime, today I tried flasing PixelExperience. After installation, phone stuck at Google boot animation screen. Now I want to boot back to recovery, but I am unable to turn off my phone, pressing and holding power button restarts it. I cannot hook into it via ADB either, as it says unauthorized device. What are my options? How can I boot to recovery?
Press and hold vol up + power and do till you feel vibration and then when mi logo appear leave.
Do update what happened

Flash Lazyflasher from twrp
Hello,
as I wrote in this (now locked) thread, I installed Superior OS and got stuck in bootloop. I get "Galaxy S9+" screen followed by system bootanimation, which repeats itself indefinitely. It doesn't restart by itself, it just boots endlessly.
The problem here is that I can't access recovery or even download mode. I tried to restart (power + volume down) and then quickly press combination to access recovery or download mode. No luck. I couldn't even turn the damn phone off. I just kept restarting.
So I let it drain the battery hoping I could then power the phone on with correct key combination. I tried holding bixby button + volume down while inserting USB. It just started booting up to system with boot animation. I tried holding bixby + volume up, or even power + bixby + volume down. No luck either.
I got correct USB drivers installed, as I flashed the phone with Odin in the past. Odin recognizes phone while it sits on boot animation, but it won't start flashing. ADB or fastboot do not work on bootanimation, as the ROM is freshly installed. I presume it has ADB turned off by default...
I'll be grateful for any ideas and suggestions.
No escape , man. I tried all ( check this rom for galaxy note 9 )
Nice...
I went to service center, they said they can fix it for me. 40 euros for reflash (download mode isn't necessary), 100 euros for complete unbrick. I hope the unbrick isn't necessary and the bootloader is intact. I'll post with update.
