v20 bricked help - LG V20 Questions & Answers

so I have a us996 I unlocked the boot loader installed twrp installed a rom. then stupidly I reset the phone inside android.
Phone kept looping to twrp even after reinstalling in twrp and wiping everything trying multiple times
I found this thread that said try this in twrp cmd
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/misc
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/fota
After that it would not boot at all. I kept getting device not secure Red boot locker screen. I could enter download mode and fastboot. Recovery does nothing.
I was able to flash with lg up and I got all the way to phone reboot but the phone just went right back to fastboot. Took many attempts with lgup and lgflash just to get it to do that.
Fastboot wont let me unlock it now, I cant install twrp again. Im stuck
currently the phone just boot right to fastboot but will enter download mode. If I try factory recovery erases and then its right back to fastboot.

Hard bricked OPT Boot loops after using MSM tool

I haven't modded the phone yet but installing oxygenos 3 it froze, so I turned it off in the process and bricked it
I then followed this guide method 1 https://forums.oneplus.net/threads/...ck-guide-for-a-hard-bricked-oneplus-2.347607/
but after using the MSM tool and pressing start, after it finishes the phone keep bootlooping
I can enter fastboot if that's any use
Is your bootloader unlocked by any chance?
If u can go to fast boot u can check by opening the adb command window and typing fastboot oem device-info.
If it is, flash TWRP and install stock os?
If it's not, have u tried to boot into recovery on the phone? Im not sure, but it might be possible to flash through adb.

Stuck on Bootloop & FirstAid kit won't help. Any Ideas? Please Help

Hello everyone!
Okay, so I'll try to keep it as short as possible but with the most information I can give ofc.
So here's what I did with my Oneplus 2:
- unlocked bootloader
- flashed custom recovery (twrp)
- flashed superSU.zip
- flashed xposed.zip
- used it for about half a year if not even longer
everything on Lollipop 5.1 stock rom so xposed would work.
Everything was fine but some day when I wanted to enter twrp recovery it didn't work. (I swear, this is the most illogical thing ever but I DID NOT CHANGE A THING!)
I tried to enter recovery via fastboot but that didn't work either.
So I reflashed latest TWRP recovery.img for OP2 via fastboot.
When I pressed power + vol. down to see if it'd work nothing happened.
When I tried to enter recovery when my system was booted via power button->restart->recovery my phone got stuck in a bootloop.
I had to go in fastboot mode to enter "fastboot continue" in order to get my phone booting normal again.
Then, one night when my phone was in my pocket it vibrated and got stuck in the bootloop again, even though it was booted into system and locked last time I used it (minutes before that).
I had no access to a computer at that moment so I had to wait for a few days.
Now when I boot my phone in fastboot mode and try to enter "fastboot continue" on my cmd nothing happens with my phone and cmd says "(command write failed (Unknown error))" even though "fastboot devices" shows that my device is connected properly.
I also tried:
- the FirstAidKit, copied the Win Files in my fastboot directory and started the firstaid.bat but it stops on "fastboot flash boot boot.img" (I waited for like two hours).
- a different USB port (USB 3 and USB 2)
I am kinda depending on my phone so yeah..
If someone knows how to fix this I would be very grateful.
Have a good day/night

Do you have a backup??
If yes, download the latest official OS from Oneplus and the stock recovery. Flash the stock recovery. Try rebooting into stock recovery. If it succeeds, wipe everything and flash OS via adb sideload.
Honestly, I can't guess what went wrong with your device. Maybe it could've been some app which crashed the entire system.

Same problem as with the FirstAidKit:
"fastboot devices" does display the device but "fastboot flash recovery recovery.img" doesn't do anything (I waited for 1h just to make sure).
I'll try this Mega Unbrick Guide for A Hard Bricked OnePlus 2 next, even though I can get into fastboot but since it doesn't do s**t I'll have to give it a try. I mean, what's the worst thing that could happen? That my phone gets bricked?!
Haha.... hmm.
I'll keep the person(s) updated who care to know what's happening.

Am I bricked?

I tried rooting my phone and think I bricked it. I followed the instructions here:
https://forum.xda-developers.com/v20/development/ls997vs995h910-dirtysanta-bootloader-t3519410
I got to the
I got as far as booting into TWRP for the first time and did the format. It wasn't clear to me where I could flash SuperSU.zip. Even though I had previously downloaded it, I couldn't find it. I presume it got wiped out when I formatted.
I then tried to reboot and it got to the Verizon flash screen and would go no further. ADB saw the device so I ran ADB reboot recovery and it got to the same spot.
Then I tried fastboot flash boot bootbackup.img and fastboot reboot. It then booted to a screen that is just a bunch of gray lines (I can see the VZ splash screen behind it) but ADB does not see the device.
This is where I'm at and can't seem to get back to TWRP or anywhere else. Is the phone hosed?
okay so I got to the same exact spot and got stuck for a while I believe. when it allows adb support on the verizon screen, preform the adb command for booting to the recovery and it should boot into twrp if you flashed it right ealier, just flash weta or lineage os on the rom slot. if not, download the kdz for the phone, lgup and uppercut and start fresh
Only advice i have is this: Keep trying all the steps untill you can flash raid your system..... and keep formating your phone (volume/power, untap-power at logo, volume/power) until all the steps have worked.

Messed up data partition, stuck at recovery, flashed EDL but won't start

hey hey,
I am sorry to bother everyone again. After successfully installing RR Oreo yesterday. My phone without a particular reason decided to restart today and go into a bootloop on the zte logo. wipe + reflashing did bring me past the logo but the bootanimation was playing forever (waited 20min). I think I messed it with the data partition encryption because I have been asked for my unlock pattern. I tried wiping and formatting data but twrp was unable to mount it. Therefore I decided to just go back all the way and flashed the B09 EDL from the EDL Tool thread.
edl flash went through smoothly but the system still gets stuck on the bootimage (again waited for 20 minutes now).
when booting the phone it flashes recovery android and then turns black. EDL mode still works.
I HAVE NO IDEA IF ITS CHARGING
however I don't know what else to do and I would really really like to have just a working phone again.
thanks for your help

exactly what I did to get here :-/
What is the model of your phone? A2017G?

yes it's a G
let me quickly sum up the current state:
the bootloader unlock screen is no longer displayed (which is very weird)
twrp gets stuck on the teamwin screen
holding power or basically any kind of reboot automatically boots into twrp
the phone is charging in this state and it is recognized by adb with the correct id but as "offline" similar to when you would connect it but not unlock it
the EDL I used is a B09 however I am coming from RR-O-v6. EDL full flashs "everything" therefore wondering if the bootstack B32-B10 I flashed only works with oreo roms etc. does not make any sense because twrp should work regardless, right?
I see that the edl tool can unlock the bootloader, does it make sense to actively unlock it (after full edl flashing B09 again) through that option in order to get twrp working correctly?
booting up to the twrp start up image I get adb access in recovery state
trying to actually use the recovery fails though
adb shell recovery --wipe_data
RECOVERY_SDCARD_ON_DATA := true
I:Lun file '/sys/devices/soc/6a00000.ssusb/6a00000.dwc3/gadget/lun0/file'

or at least stops at this line.
adb shell commands work mostly apparently
Is it possible to format data with ext4 from adb?
you can put twrp 3.2.1.7 in Axon7_EDL_Tool\flash\recovery and rename it as recovery.img, then flash recovery from Axon7_EDL_Tool.
then check if you can actually use twrp.

tried flashing recovery through edl again like you said, both with 3.2.1.7 and 3.2.1.0. This is pretty much the state I am stuck in. After the flash completes successfully I reboot the phone from the tool and it immediately boots to recovery, shows the teamwin / twrp logo screen and stops there.
I can connect through adb in this state. The device is show with the correct id as in recovery. However I can not for example wipe data. If I try to do that the phone fails to respond. adb shell ls works on the other hand.
but still I don't get into twrp in a way in which I could actively do anything
adb works on recovery mode is weird.
you can try following options
1. Axon7_EDL_Tool flash full with A2017G_B11_MARSHMALLOW_FULL_EDL
2. Axon7tool write recovery on edl mode
https://forum.xda-developers.com/axon-7/development/axon7tool-flash-backup-boot-recovery-t3514254
3. Axon7toolkit, you need bypass virus check, there are a lot of options, including flash twrp, restore from hardbrick on edl mode.
https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108
4. if everything failed, you can try 4th category brick repair

Unable to flash TWRP on Moto e3 power with latest software update

I'm trying to flash TWRP (twrp-3.2.1-0-taido.img) on my Moto E3 Power. I had successfully rooted this phone once, and that's why the phone is unlocked. So when I try to flash custom recovery using the command "sudo fastboot flash recovery twrp-3.2.1-0-taido.img", it says it completed successfully, but instead of booting into twrp, my phone is starting up completely. When I tried booting up custom recovery using "sudo fastboot boot twrp-3.2.1-0-taido.img", the same thing happened again.
The software on my phone is "23.0.XT1706_S151_180706_ROW". So far I've been unable to flash twrp on this phone, but I got it to work an year ago. Please, can anyone help me what's going wrong here? I'm following the tips on xda-forums using which other users were able to flash the same recovery on their phones.
you can try this
