Bricked VS995 after Dirty Santa attempt - could use some help! :(

So my VS995 (Verizon LG V20) is stuck in a fastboot loop. I can't do anything outside of fastboot. I got to after step 3 in the Dirty Santa root method and could not get the phone to boot into TWRP recovery. I kept getting an ADB device offline error and could not get ADB to see my device to initiate the "ADB reboot recovery command".
In a stupid and drunk state I did a "fastboot erase system" and thats what locked me into the fastboot loop.
Any help is appreciated as my V20 is now unusable :crying:.
I guess I would need a stock boot image, and stock recovery to get back to where I started. If anyone could point me in the right direction and help me get my phone back (and possibly rooted), I would be more than happy to donate via PayPal .
P.S. The LGUP software used in the how to restore v20 thread linked-> ( https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903) does not recognize the model of device giving the error ("you have to select a known model, please")

I was able to flash the appropriate stock .kdz file (THANKS dwertz!) but my phone immediately boots right back into FastBoot Mode
Do I need a stock Boot.img file?
I can communicated with the device through the PC's terminal using fastboot. Are there any fastboot commands I could try to boot into the stock firmware I just flashed? Are there any partitions I need to erase or format?
Any help is appreciated!

to my understanding, the kdz file contains the stock boot.img and stock system.img, everything to bring the device completely back to stock .
In fastboot to boot to the system the command is "fastboot reboot"

After flashing the stock .kdz firmware for the VS995 fastboot is no longer working and giving me the error FAILED (remote: unknown command).
My phone can not get past FastBoot! :crying: I think I really bricked this thing now. My bootloader is locked, fastboot commands don't work at all.
The only thing that does work is download mode (holding volume up and plugging phone in) and I am able to flash the vs995 firmware from the lg website but i STILL can't boot into anything but fastboot.
Does anyone have any suggestions as to what I can try to fix this thing. I think i'm doomed. I may try to flash the stock us996 firmware because at this point it seems like it wont get any worse.
Any help would be appreciated!

did you ever get any help? I would go directly to the dirty santa thread and make your issue known. I'm not sure how much help I could give you but if no one else is willing to help I can try.

Did you flash the kdz using Uppercut?

imucarmen - I can't post in the dirty santa thread because I am a new member to XDA (been coming here for years just never made an account )
bond32 - Yes I was able to flash the .kdz using Uppercut+LGUP but my problem is not fixed. My phone still boots right to FastBoot Mode in the "Locked State" to where I can't issue any commands or alter any partitions.
This makes no sense to me if LGUP is able to 100% flash the stock firmware, WHY CAN'T I GET OUT OF FASTBOOT! Lol
Does anyone have any ideas as to what I could try to unbrick this thing?

I know it's a different issue from the one that I had, but the LG Support Tool method that KedarWolf posted might help solve this issue too.

Splinter 77 - Thank you for the suggestion. I have been trying to get this tool to work for a couple hours and everytime it hangs on the Downloading Firmware section. No matter what I try I can't get it to download the firmware....

Does anyone have some ideas I can try? I'm up for anything at this point!

Did you try pulling the battery, put the battery back in.
Hold the volume down and power button at same time. When the lg logo shows up let go of the power button but continue to hold the volume down and press the power button again. It will bring you to a screen tgat has 2 questions. Answer yes to both of them. Then reboot. I believe that resets the way the phone boots almost like resetting a cmos

ahh i got it man! @Kevin_xail
i dont know if this will help seince u relocked, but do the factory reset dance
hold the vol down and power and put in battery as soon as its on click the power button and re hold it. it will get to recovery, it took me hours but its there.

I had tried that a few times after reading about it but I'll try now for an extended period of time and see if I can activate it. I'll report back with what happens, thanks for the tip dwertz and Team DevDigitel

Well I got in to the recovery menu and reset to factory settings and wipe cache (the only two options) but I still am booting right into FastBoot and can't escape!
I even flashed the stock .kdz again after the factory reset and wiping cache and I'm still stuck in FastBoot
Any other suggestions to try?

When you have a unlocked boot loader and you do a factory reset, I believe it wipes the OS from the phone giving you no OS. If you can get back to recovery, flash this rom https://forum.xda-developers.com/v20/development/vs995-vzw-nrd90m-modded-notsostock-rom-t3525864
That will at least get you booted so you can flash the kdz.

I can't get into any kind of recovery to flash a rom though

fastboot flashable boot.img

Hi !
I might have erased the boot partion. I still got the unlocked bootloader screen, and can still get in fastboot, but that's it. I can't boot in TWRP. I've tried to flash the boot.img from the stock zip, but it doesn't work... anyway to fix this ? It's the A2017G model. All i need is to get into TWRP.

you can try getting into EDL and using MiFlash to flash one of the zips on the Russian page 4pda. Go to the debrick page (the one with the phone carnage pictures inside), find the links for the chinese full recovery package. it will get you to the 4pda page. from there find a package that suits your needs (there is one with aboot and fbop) and flaah with MiFlash
Otherwise download the full B10 recovery package and flash it with MiFlash. you won't lose data but it might conflict if you were on Nougat

I'm in this situation for some days...
No EDL, No recovery, only fastboot and FTU modes are accessible.
And we can't flash via Miflash. It sees the phone only in fastboot mode, and can't flash it.
 @op : 2 ways to recover :
- Test points method to force EDL and flash via miflash
- Return to ZTE
If any1 has other solutions ...
FYI : My tests so far :
- Flash boot / reboot / flash recovery : Stuck on ZTE logo, red led on permanently
- Hot load recovery (fastboot boot twrp.img): Command unknown
- Format userdata/cache : No work
- Flash via Miflash in fastboot : "Can't find Eraseall except Data.bat"
- Change drivers by some others one : No luck

I don't know what you mean with FTU mode, but if FTM is meant you should be able to send a "reboot edl" command to activate the EDL mode.

Humm ... Early morning for me ... i meant DFU. Vol+ & - while powering the phone Result on a black screen, and driver is recognized as Handset Diagnostic Driver (DFU COm port x)
Ind in that kind of brick, FTM is not accessible either.

Yeah that pretty much sums it up. If you get ZTE handset diagnostic driver on Ports COM&LPT you'll have to take your device apart and use the test point. If it is recognized as Qualcomm HS-USB QDLoader 9008 it means that you're on EDL. I'd reccomend trying to use miflash like i described, if it doesn't work return it or take it apart

Maybe a bit late for a reply, but I was able to get out of a similar situation (from DFU) by holding power and volume down for a long time. That got me to FTM and then I could reboot into edl via "adb reboot edl". Then I used the Axon7toolkit to flash fastboot and from there I could get to twrp and back in business. Any questions, let me know.

@Piet : How long for the PWR+DWN ? I've tried for something like 40/45 seconds, without success.

From what I read you have to let the device discharge totally, then you can get ftm. I had my battery fully charged when i bricked so i just did the 4th categ unbricking process

Help please can't see my phone in adb

I've had my Essential two weeks i was on 8.1 beta.Today i unlocked the boot loader.Then installed twrp while in twrp i side loaded magisk.I went back to fastboot then hit start .The phone just went into a bootloop.I Was able to go back to twrp 2 times but now i can't get back to any type of recovery.I Can get back to fastboot mode ishow all the info and secure boot says yes and device state unlocked.My pc see essential phone fastboot in the device manager but i can't get adb to see it .Can anyone help me ?

forgot something
looks like i skipped this part . Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.Is there anything i can do?

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.

WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.

I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help

This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:
fastboot flash boot twrp.img
and I get:

How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.

The good news is that you've got the dirtysanta bootloader installed (that's why it's reporting us996) so you should be able to fix it without using LG UP and having to redo most of the process.
Install twrp by doing fastboot flash path/to/twrp.img .then pull the battery when done. Then enter twrp by using to volume key method (hold volume down, press power until the screen turns on, then tap power repeatedly until a menu asking to factory reset appears, say yes (while twrp is installed it won't actually wipe anything).)
Flash a rom (a stock one is here), and magisk.
If you can't use an sdcard to get them accessible to the phone in twrp, in twrp you can go into advanced then sideload and connect to a PC and do adb sideload path/to/rom-or-magisk.zip

to totally back out and bring your phone to totally stock use download mode (from powered off hold volume UP while connecting to the pc). The screen will be still messed up but it will still work on the pc.
Use patched LG UP in partition dl mode to flash everything with a stock h990(ds) kdz.
Once you start using dirtysanta next time (if you decide to try again) be very very careful when using LG UP (easier to just use stock flashabile zip) unless you want to redo the above and flash EVERYTHING back to stock (if you ever flash the aboot partition in LG UP and anything ISN'T stock it will brick you! This mostly applies to partition dl mode since upgrade mode flashes everything, but partition dl mode is the only mode you can even potentially flash things and keep root (but I don't encourage this... its easier and saferto just use zips in TWRP to flash firmware (mostly stock basedrom or so called stock flashible zips tend to also flash all of the firmware except parts needed to keep root. )

But did you use partition dl mode? It alone bypasses the model checks.
Partition dl mode isn't in regular lg up, you need the special patched version I linked (replace the files of your regular lg up with the special version)

Try uppercut then. Use upgrade mode if it works but partition dl mode is missing. Note uppercut asks for lg up version 1.14 . I can't remember what version the patched one is but you may have to reinstall that version instead.

Trying to flash TWRP but no success (stuck on Fastboot mode)

I have been on a journey trying to go back to my T-Mobile OnePlus 6T back as my daily driver but the official updates killed the device for me. I have been successful in flashing it to the international version and now the device is on A9. I am trying to get it updated to A10 but in order do that (does not take OTA updates or can not flash within the updates app) I have to flash in recovery. Right now it is on stock recovery so I am trying to flash TWRP.
The problem is now that everytime I run the command " fastboot boot IMAGENAME.img" the phone restarts (as expected) and boots into fastboot but stays stuck in the Fastboot Mode screen.
I tried different TWRP images (older and the most current version per https://dl.twrp.me/fajita/ ) but I keep getting stuck in the Fastboot Mode screen. The last thing I was able to do without issues was unlock bootloader using fastboot.
I just need to be able to flash TWRP on the phone so I can still the final stock image so I can go back to using it as my DD.
EDIT: Disregard everything I fixed it. mods, please delete thread.
EDITR 2: Disregard that last edit lol Yeah I still need help. I am now tryingto flash twrp on a second 6T and the issue described above still applies.

You can try this version. Also try unplugging the USB after it reboots. You aren't getting any crash dump screen? So it should be working.

Tried your image and still same result. I am running following command
Code:
fastboot boot TWRP-3.6.1_11-OP6xT.img
The command window outputs the following
Code:
Sending 'boot.img' (34964 KB) OKAY [ 0.747s]
Booting OKAY [ 0.092s]
Finished. Total time: 0.860s
The phone then reboots into Fastboot Mode logo and stays stuck there. I even tried unplugging the USB after it reboots as well.
I even tried using the flash command instead of boot but no success.

How about fastboot boot recovery? Should be able to get into recovery somehow. Doing fastboot flash of twrp will mess up your boot partition but either way you still should be able to get into recovery somehow. There is the msm recovery tool you can use as last resort but it will relock your bootloader

Actually fastboot doesn't let you use boot recovery command I don't think. Only adb. But once you are in fastboot can't you choose to reboot recovery with volume keys?

When I am in fastboot mode, yes I can choose recovery but it takes me to the stock recovery. I do not have a option to flash any zip files there

Maybe you need a twrp for Android 9 since that's what you are on. But fastboot boot twrp should just take you there. Either have to find one that works or go msm route. Maybe windows not reading it correctly also. You using CMD or PowerShell?

I tried both CMD and PowerShell. I am going to try a A9 version of twrp
EDIT: I am using twrp-3.6.1_9-0-fajita.img (which I assume is for A9) and still get the same result. Even tried a different usb port.. not sure what i could be missing. I also did the instructions as advised straight from twrp's website.

I don't know bud. I guess msm tool is the way to go then

Curious did you have the twrp file in same folder as adb and fastboot?
