Help, LG V40 sprint variant with pie. Decryption unsuccesful - LG V40 Questions & Answers

After I did a factory reset via twrp, the phone is now saying a message after booting up "Decryption unsuccesful"
It says that it was able to use a password but that the data is corrupted. It ask to perform a factory reset but since my recovery img is twrp it just goes back to twrp and even after doing factory reset via twrp again i still get the same message.

You need to replace TWRP with your stock boot.image after performing a data wipe not just a factory reset.

Can't factory reset?

I tried the instructions posted at the Motorola site here:
https://motorola-global-portal.cust...r_detail/a_id/94936/p/30,6720,8696/reg/348778
It doesn't matter if I do the software reset from within android or the external reset, it won't work.
If I try the reset within android, it reboots and then boots normally.
If I try the external reset, I can get to the bootloader but when I choose 'factory' it reboots normally, not to recovery.
Device is rooted.
Any help?

Where did you get the stock recovery and how did you flash? I'm stuck in FC look and can't factory reset.

I got the image from here:
http://sbf.droid-developers.org/ghost_rcica/list.php
Booted the phone to the bootloader (adb reboot bootloader) and then used fastboot to flash the stock recovery:
fastboot flash system recovery.img
Then I was able to do a factory reset using the typical instructions posted in the OP

TWRP - Not wiping

I've been rooted since I got the Nexus 6 and recently have been having issues with TWRP. I can back up and restore but it won't do a factory data reset or wipe of any kind. I've tried with TWRP 2.8.6.0, 2.8.7.0 and 2.8.7.1. When trying to flash a new rom I select factory data reset, even tried advance wipe and wiped the whole phone including internal storage. After flashing the rom boots up like I dirty flashed it. I've even returned to stock, rerooted and the same issues with TWRP - it just won't wipe. Any suggestions would be sincerely appreciated as I'd like to flash a Marshmallow rom.

When you have TWRP installed and bootloader unlocked you could follow the instructions in the OP of the JDX rom.
What I would do: fastboot flash M-bootloader and M-radio. Reboot to bootloader and fastboot flash TWRP 2.8.7.1. Than flash the JDX 4.0 rom.
Power off the N6. Reboot in recovery TWRP and wipe cache and do a factory reset.

I thought about that but not sure it would boot if not really wiping.

You need to connect N6 -> PC.
And use a dosbox as administrator.
You have 2 options to boot in bootloader mode.
From the PC or pressing buttons Power + Vol down. So why no boot ?

I've been messing with the phone for about three hours today and got it back running. Will give that a try in a day or two - so frustrated right now may make a major mistake.
I would still like to find out why TWRP has stopped wiping on my phone.

phone keeps rebooting into twrp

So my phone was stuck at Android is starting, so I tried to perform a factory data reset through the settings menu. Now it will only boot to TWRP no matter what I've tried. I've formatted everything reinstalled the system and all that. Anyone have an idea besides full on reflash?

Reflash your boot.img

Reboots to TWRP Recovery

I have the XT 1805
This is the European Dual Sim version 32GB.
I unlocked the bootloader and got root using this: https://forum.xda-developers.com/moto-g5s-plus/development/root-moto-g5s-plus-t3673287
I was unsuccessful flashing the TWRP recovery from the link in the OP. Other people in that that thread noted similar issues. I flashed TWRP from this link:
https://forum.xda-developers.com/showpost.php?p=74105503&postcount=27
Whenever the phone boots, it boots directly to TWRP.
I also enabled encryption.
TWRP says the encryption password is incorrect.
When I cancel the ready process, I can go into TWRP and boot to bootloader from TWRP.
From the bootloader/fastboot screen I can boot into system.
I don't want to jump through these hoops every time I reboot. How do I fix this?
Also, I cannot factory reset. Factory reset takes me to TWRP. After I do the bootloader dance, I'm back to the system before the factory reset. It's as if factory reset never happened.

First of all we need to make a fresh start so
1) let's flash the stock ROM on our device
2) now once we are on stock it time we flash a valid TWRP recovery file here's the link : https://forum.xda-developers.com/moto-g5s-plus/development/recovery-twrp-3-1-1-r7-t3694910
3) once it's done let's boot to the recovery and if it asks for any password or pin let's cancel it and swipe to allow modifications now let's go into wipe section > format data > type yes.
4) once it's done let's go to reboot section and reboot to recovery. Once again let's boot back to recovery if we get any red lines highlighting " unable to mount system " so to fix it let's go to mount and mount system,data and now flash magisk or super su if we want root or straight away flash a custom ROM due to this atleast we will not get a system status modified in our bootloader
Thanks for reading .

Factory reset and patched boot.img

I have to perform a factory reset on a rooted pixel 5.
Before I do, have I to flash the original boot.img to avoid bootloop?

No, a factory reset just wipes data.
If you are trying to return your phone completely back to stock, I recommend using the Android Flash Tool. Your bootloader must be unlocked. Use the tool to flash the latest factory image; make sure you check the "Wipe data", "Force flash all partitions", and "Lock Bootloader" options.
