Can someone help me restore the table as of now it says EFILINUX EROR [Start_boot_logoc:498] No valid target found, Fallbacking to MOS

I followed this guide here youtube.com/watch?v=C8Y9pybocPA and the update failed to reinstall the original firmware.
Well I did some digging and it looks like my tablet is in DNX_OS mode. I can get it into an odd fast boot mode by holding vol up + power. The screen says FastBoot Starting...
Current firmware version :206.5

I found the Intel Platform Flash Tool Lite that does recognize it but I do not have the correct firmware rom file to flash. The factory one from Asus is not accepted.
Can any one assist?

Hi I have asus tablet model me173x_S_user and trying to update Android version there from 4.2.1.
All of the reference I found was to firmware version which was different. Can you point me how I can update Android on this tablet without bricking it.
thanks a lot in advance.

     * Your warranty is now void.

     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at me for messing up your device, I will laugh at you.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.

    About this project

    This is not a regular ROM. Usually, ROMs are based on certain components provided by the vendor (e.g. the heavily modified kernel and certain proprietary components). In contrast, this ROM makes use of a largely unmodified mainline Linux kernel together with many open-source components. Only a tiny bit of firmware is taken from the stock ROM.

    This has many advantages for security and maintainability, but also means that certain hardware features (e.g. Camera, GPS) are difficult to implement because they require significant effort and a lot of reverse engineering. Nevertheless, this ROM has reached a state where it is very much usable with the majority of functionality implemented.

    (See "Development" in the GitHub README for a more technical introduction...)

    New features
    • Android 9 (LineageOS 16.0) with latest security patches
    • Linux 4.19 kernel
    • Meltdown, Spectre, RIDL, Fallout, ... fixes
    • Vulkan graphics (experimental)
    • Less/no bloatware
    • Full backlight control (allows much lower brightness)
    • F2FS (with a compatible recovery)
    • Signature spoofing (allows using MicroG instead of proprietary Google Play Services)
    • WireGuard
    Tested features
    • Display, Backlight control
    • Graphics (OpenGL etc)
    • Touchscreen
    • WiFi, Bluetooth
    • Audio: Speaker, Headphones, Microphone
    • Battery, Charging
    • Sensors: Accelerometer, Magnetometer
    • Internal Storage/External Storage (SD Card)
    • USB, USB-OTG
    • Hardware video accelerated codecs
    Planned features (not working yet)
    • Suspend/Deep sleep states
    Not planned
    • How is the battery live? Screen-on time is probably similar if not longer, but there is a lot of battery drain in standby mode (even worse than on the ASUS system). I recommend that you turn off the tablet when you're not using it.
    • How do I obtain root access? There are various ways, but the recommended way for LineageOS is to flash addonsu. (Available below.) However, note that this will break SafetyNet. Use Magisk alternatively.
    • Can I use Netflix with this ROM? Yes, although you will need to build and flash the Widevine DRM addon manually (see below).


    1. Make sure you are running Android Lollipop (5.0).
    2. You need an unlocked bootloader. LineageOS 16.0 requires me176c-bootstrap 0.3.0, included in me176c-boot 0.3.0. (The old "Intel" bootloader is no longer supported.)
    3. Install TWRP
    4. Make a full backup of the ASUS system. You may want to go back to it.
    5. Do a full factory reset. Wipe data and cache partitions.
    6. Install the main system using the flashable ZIP below.
    7. If needed, install additional addons not included with the main system (see below).

    There are various packages you can flash for additional functionality. Most of them are proprietary. All addons persist during LineageOS updates, so you do not need to flash them again after updating.
    *Houdini/Widevine: I do not provide pre-built ZIPs for those two addons. (See this post for more information.)
    They can be built easily on any Linux distribution using android_vendor_google_chromeos-x86. Takes just a few minutes (depending on your download speed). No development experience or Android source code required.

    If you are unable to build it, someone else may share a build with you. In that case, you can verify its integrity using the SHA-1 checksums available in the release notes.
