Boot Verification Fail Cause: MISMATCHED_SIG_LEN - T-Mobile LG V10 Q&A, Help & Troubleshooting

So me trying to install a MM rom on my LP phone have caused me this error. Is there any guide out there that would help me fix this?
I have tried booting into TWRP using vol down + power but it just keeps leading to this error. I can't even get into download mode. I am guessing im SOL?

Factory reset first , TWRP is started next boot

Whenever I do Factory reset all I get is the boot loop, also for download mode.
EDIT: FIXED! I am just an idiot at reading.

you can try to install nexus toolkit ( support LG adb ) . check at bootloop , reinstall TWRP image and choose reboot recovery

Sounds like you have some reading to do start with this
https://www.google.com/amp/s/forum....-g5/how-to/info-autos-g5-thread-t3350648/amp/
It's a good read...... If you're still stuck know that after you fastboot flash TWRP you have to unplug and pull the battery. Because if you don't the stock recovery overwrites the custom upon reboot.
If you don't flash magisk or su or dmvertify once in recovery it will flash stock recovery upon reboot.
maybe the problem is to pull battery out... cause i already done this and i had a twrp and it work great... until installing the stock kdz

Stuck at Android boot screen after reset factory

Hi guys,
I'm using Phh's rom v9 in my Huawei Mate 10 Pro (BLA-L09).
Everythings was ok until I decided to proceed to a factory reset from the Android menu (Settings>System>Factory rest).
Now I'm stuck on the Android boot screen. I can see the "android" text with a fading effect, but it doesn't boot (the fading animation works).
When I wait 5 minutes, the device reboots to eRecovery screen, where I can only choose between "Download latest version and recovery", "Reboot", "Shutdown".
I can still go to fasboot mode and I can still boot on TWRP too (I'm using this version of TWRP).
I've tried to reflash the rom (Phh's treble version 9), but i've still the same problem.
When I try to flash another rom (for exemple LOS 15.1, from here, or Phh's treble version 12), I got another problem: bootloop.
When I try to do a facroty reset from TWRP, same problem: stuck in Android boot logo.
Do you know a trick to solve this problem?
Should I go bad to stock recovery to proceed to a factory reset?
Should I go back to stock Huawei rom?
Should I buy FunckyHuawei credit to use their unbrick tool?
Should I stop hacking my phone like I'm a pro?
Thanks for your help!

Thank you for your answere. How do I proceed to use stock recovery?
I guess I have to find the stock recovery file and flash it with this command:
Code:
fastboot flash recovery_ramdisk stockfile.img
Am I right?

Yes, that's correct.
Here's stock recovery: https://mega.nz/#!RTAwwRaD!vX6CCS4jJ4RnARMz5_lAg_O5Wn_-X25qKVp3hhAc_AQ
(It's from C636B134 but shouldn't matter)
Ok thank you, I can now boot on the Phh Treble v9 rom, I'm no more stuck on Android bootscreen.
I've tried other roms again (Phh treble v12 and LOS), still doesn't works, I can only boo on Phh's rom v9.
But I guess it's part of another problem.
Thank you!

Weird.
Did you try flashing SYSTEM.img from LOS and then Factory Reset from Stock recovery?
Yes. Here are the steps I've followed:
Downloaded LOS rom
Plugged my phone on usb
fastboot flash system sysyem_LOS.img
fasboot reboot
The phone bootloops 4 or 5 times
Factory reset asked after bootloops -> accepted
After factory reset, the phone reboots to the screen with "Download latest version and recovery", "Reboot", "Shutdown".
Maybe am I doing something wrong?
Should I run Factory Reset manually before bootloops?

Yeah, go to recovery right after flashing and factory reset.
I've tried again with LOS and Treble v12, same problem. The only one booting well is still Treble v9.
Hi again guys,
I get stuck on the Android boot logo again. I was using AOSP Treble v9, and decided to go back to stock version as explained on this guide :
https://forum.xda-developers.com/mate-10/how-to/guide-mate-10-flash-oreo-update-package-t3716814
It did not works, I get stuck on the Android boot logo.
I've tried to go back on AOSP Treble v9 by flashing the recovery_ramdisk to the original one and flashing the v9 AOSP Treble, but I still get stuck on the Android boot logo.
Any idea how to boot on any Android version?
Thanks.

Galaxy S7 stuck on bootlogo even after flashing new firmware from Odin

Hello... so ugh I have a rather problematic S7 (SM-G930F) that would automatically go to recovery and not boot to Android. I figured I could fix that if I re-flashed firmware but it turns out that wasn't the case
After Odin reported a successful flash it booted to recovery again instead of trying to boot into Android, recovery mode also displayed some sort of verification errors?
Here is a picture of the recovery mode, other than that i don't have any other clues as to what maybe wrong

Do a factory reset in the recovery menu.

Doing a factory reset does not belp. Nor does flashing a brand new stock ROM which is rather bizarre

S9+ stuck in download mode

So, I had Magisk and my phone was rooted, but when I decided to unroot and did a complete uninstall of Magisk: my phone restart but it keeps on restarting continuously, so I decided to go into recovery mode and followed tutorials on how to fix it. Firstly, I reset everything using the TWRP advanced wipe feature (I ticked everything). Then, I decided to flash LineageOS (the file attached) with TWRP and reboot, now the device is stuck in download mode. For some reason, I cannot boot into recovery mode and It's just going to go to be stuck forever in download mode, every time I restarted it or try to boot into recovery mode. What should I do?

Use Odin to flash latest stock firmware and start again.
To install lineage with twrp in wipe menu - advance wipe select only Data, System, Cache and maybe Vender if you have it after you have installed twrp properly first.
It's resolved now

Boot loop and TWRP message: "os not installed" on s9+

I have an s9+ i flashed it to a costume rom (TWRP) and then rooted WITH NO BACKUP it worked perfectly with no issues, best Android experience I've had until a root app required reboot to apply changes once my s9 tries to reboot it became stuck in a boot loop and i booted up to TWRP and did a factory reset and wiped/formated all my data then tried to reboot, and TWRP shows a message: "os not installed" i proceeded anyways and it's still stuck.
I know how screwed up I am but I need a solution pls...

Not sure why you did a factory reset or wipe your phone but the easiest solution is to install stock samsung firmware with odin and start again.
What app did you install?
