Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

About

This port of TWRP is built alongside the LineageOS ROM using the same kernel. It's the recommended recovery if you want to use the LineageOS ROM (or another ROM based on it).

Features
  • TWRP 3.3.1 (built in LineageOS 16.0 tree)
  • F2FS
  • USB OTG
  • Full disk encryption
Installation
  1. Install ADB and Fastboot on your PC. There are guides available online for this, for example on the LineageOS wiki.
  2. Make sure you are running Android Lollipop (5.0).
  3. You need an unlocked bootloader. TWRP 3.3.1 requires me176c-bootstrap 0.3.0, included in me176c-boot 0.3.0. (The old "Intel" bootloader is no longer supported.)
  4. Boot into Fastboot mode: Press Volume Down + Power to turn the tablet on and select Fastboot mode in the menu.
  5. Flash the downloaded TWRP recovery image using Fastboot:
    Code: 
    fastboot flash recovery twrp-recovery-3.3.1-20190609-UNOFFICIAL-me176c.img
Usage

Before you start flashing ROMs I recommend making a backup of your system, especially of the Factory and Vendor Data partition. These tend to get corrupted for unknown reasons, so it's good to have a backup.

TWRP 3.2.1 (2018-09-26)
lambdadroid said:
New features
  • Added Backup/Wipe functionality for "ASUS Product Demo (APD)" partiton.
    • This partition only contains some product images/videos about the tablet and is likely only relevant for the stock ROM (if at all). It has ~300 MB of space available so it works great as additional partition to place boot images/kernels on when using dualboot.
Other changes
  • Updates: Linux (4.14.42 -> 4.14.72)

TWRP 3.2.1 (2018-05-22)
lambdadroid said:
New features
  • Added USB OTG support: You can now connect USB devices (e.g. USB keyboards or USB flash drives) to the tablet using USB OTG adapters.
Improvements
  • Minor power management improvements: Put more devices into suspend when not used (ported from LineageOS ROM)
Other changes
  • Updates: Linux (4.14.19 -> 4.14.42)
  • Updated CPU microcode to 836 (2018-01-10) - includes Spectre-related fixes

Major changes
  • Kernel upgrade to Linux 4.14: Experimental, might break things. More improvements and optimizations coming soon.
New features
  • Support for full disk encryption
  • Fixed USB mass storage mode for file transfer
Known problems
  • MTP support is disabled. However, given that file transfers were already broken before I don’t consider this as a regression. You can use ADB to transfer files.

Quick question: can this image be safely flashed with the 'Flashify' app? Thought I'd ask before I attempted it. ?

Well, you still need the unlocked bootloader, which is probably something that app cannot do. Otherwise, I see no reason why it wouldn't work for flashing new recovery images. It's really hard to break this tablet completely so you can just try it. :)

Unfortunately every ROM I try to flash with this TWRP version results in error signal 7. Tried removing the assert command of the roms I try to flash (lineage and the custom rom) but no success.
I do have model K013 ;)

You may be able to launch a temporary recovery session using https://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096

But considering https://forum.xda-developers.com/showpost.php?p=79554718&postcount=47, I'm guessing you do not have a ME176CL but a ME375CL (K00X). Unfortunately, those have nothing in common with the ME176C, it has a completely different GPU and SoC. TWRP/LineageOS won't work at all for it.

An additional note for newcomers

Hi,

Thanks for this, it helped a lot as I'm completely new to this and really want to replace the old android 5.0 with something from this century.

One issue I kept bumping my head into was that after following the steps above, I could not get TWRP to work.

First installing adb on a PC, (ok)
then installing the new unlocked bootloader (ok)
and finally installing TWRP, (not ok)
after trying to boot into recovery it always ended up with "Error".

A cute little robot laying on its back with the message "error" ... No details beyond that.
Tried reflashing the bootloader and TWRP many times, including different versions of TWRP, but it would not matter.
No recovery for me.

But I'm a tad stubborn, so eventually it dawned on me to try and install the first TWRP from the list (3.2.1) and after that it booted into recovery OK and I was able to update to TWRP 3.3.3.
Now TWRP works OK (well it boots into TWRP, so I think it is now fine).

cheers!

    No, the ME181C never got the Lollipop (and as such, the UEFI) update, so you're stuck with the stock ROM and tethered TWRP unfortunately.
