For some reason im not able to make a nandroid backup of my stock rooted rom. TWRP is failing to mount data. Am I doing something wrong? I've used TWRP countless times on other devices to backup and have never had a problem.

i downloaded the 3.1.1-0 version and reinstalled but no issue here. did you edit anything or install on the wrong device? mount points are defined in the /etc/recovery.fstab file in recovery. maybe try re-downloading and installing

if you just rooted the device you're going to have to wipe data in twrp before it will be mountable

That did it. Thanks!

Hi.
Using your recovery, I get this:

"b3" devices; this is a "v521". Installer Error (Status 7)

Flashed to an older version of TWRP for the v521 and that worked. Thoughts?

What zip were you trying to flash? im guessing the first half of your error said "this package is meant for b3 devices..." or something along those lines. Im pretty sure the shabbypenguin 3.0.2.0 is b3 based, so it was generic or compatible with v521, v525 etc. . this is v521 only. I assume whatever zip you were trying to install only had the b3 assert. Most have "b3, v521" asserts in the update-script.

That error usually comes up when the recovery checks the assert in the zip you're installing, against the recovery default.prop and the v521 assert wasn't found in the zip package. So it failed because the recovery read the zip as being for another device.

Could also be your bootloader is outdated.

This started with my LTE is being slow like snail on LineageOS. Baseband wasn't showing up on status (showing unknown) so I was going to try to flash/upgrade the modem to see if that does anything. Would drop into TWRP and flash but would get that error saying this was made for a "B3" not a "V521".

So I decided to go back to stock and flash with this :
https://forum.xda-developers.com/lg-g-pad-83/development/rom-lg-stock-nougat-t3561088

But even that came up with the same errors So I downgrade to shabbypenguin's TWRP and then I was able to flash those packages. Went back to LG STOCK and tried the modem zips but to my original issue, still getting SLOW LTE speeds. Maybe my radios are kaput? APN looks correct comparatively to other US Tmobile APN settings.

You said it could be the bootloader. Wouldn't going back to stock (link above) or even flashing latest LineageOS or RR update it to the latest bootloader?

I'm in the same boat like the other guy was, every time time I try to wipe data through twrp it fails.. How am I supposed to wipe it?

@HighRidas twrp 3.2 is released, fyi

 

[vlamnire]

Does this support encryption if I encrypt with Lineage? I'm hearing some issues with TWRP in general with encrypted Nougat devices.

Has anyone flashed this successfully? I'm having "remote: unknown command" errors.

to prove that I already successfully unlocked the bootloader:

fastboot getvar unlocked

unlocked: yes
finished. total time: 0.002s

fastboot flash recovery TWRP-3.1.1-0_v521-recovery.img

target reported max download size of 536870912 bytes
sending 'recovery' (16170 KB)...
OKAY [  0.510s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.511s

Any ideas? I'd appreciate any assistance.

Must be done on 20f with dirty cow. https://forum.xda-developers.com/g-pad-x-80/how-to/nougat-7-0-v521-guide-to-update-v521-lg-t3533338

Ah. Thank you.

Someone really ought to fix the LineageOS guide page for the v521

Now I just have to figure out how to downgrade to 20f without a Windows machine to run LGUP on. I tried in a VM with USB forwarding, but no dice. The USB debugging authorization gets confused when it connects to the host and then the VM...

 

[vlamnire]

Encryption does NOT work but I think this is Lineage problem or the device doesn't support it.
When a LineageOS update comes out, and it reboots to recovery, the recovery doesn't install anything. Is this the recovery's fault or LineageOS' fault?
I also have to run this every upgrade (TWRP loop): dd if=/dev/zero of=/dev/block/platform/soc.0/7824900.sdhci/by-name/misc count=1 bs=32

Same here, I go to "Wipe" and swipe and I get various "failed to mount" errors.

You will need to format data on the wipe tab which will remove encryption and delete anything installed but will allow storage to mount.
