thx, just tried that and it work on my tb-x304F, but now rom doesn't, stuck at loading screen... Gonna try 16 later and see...

edit: 16 doesn't work here from here, https://forum.xda-developers.com/t/...-x-lineageos-16-0-for-lenovo-tab4-10.4199623/

the log said it's targeted for L version, so after flashing, it said OS not found for 304F version.

even this 17.1 version said it's for X304L, guessing that's why it stuck at loading screen.

There is? I searched through pretty much all the threads, all labeled as f/l/x, can't seem to find one that works yet Now I am stucking with a tablet with twrp recovery and no working rom to use. Going back to stock, seems wayyy more work...

edit: Holy, I can't believe this actually works in the end... what a ride.

So, affterrrr going back to the stock rom, version 7.1.1 from another thread, the OEM unlock button actually NOT grey out anymore. (Guessing the 8.1 actually greyed out your oem unlock button). Unlocking the bootloader is only matter of a single command > fastboot oem unlock-go.

So I was like might as well give this v17.1 another try, flash twrp 3.4.0-120408 (updated version I think, latest one I can find) > wipe, reboot recovery > flash rom > reboot > and it works!! Not stucking at the loading screen anymore, yay!!!? Then, bluetooth is crashing as soon as I get the past the loading screen. Finally went back to v16, and everything works so far....and flash the 17 again after 16, and bluetooth issue is fixed, everything works nicely!

    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.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

    I can't get it to flash. TWRP has been sitting for hours at:

    Unmounting System... Target: Lenovo/LenovoTB-X304:/X304L:8.1.0/0PM1.171019029/S001017_190709_ROW:user/release-keys

    EDIT: Fixed by flashing TWRP instead of just booting it. The steps I followed were:

    1. Install the Lenovo Driver from here
    2. Install fastboot and adb on your PC, e.g. from here
    3. Enable developer options and in there select to unlock your bootloader by enabling OEM unlock and enable USB debugging
    4. Connect your PC to your tablet and run
      Code: 
      adb reboot bootloader
      using adb on command line. The tablet will reboot into bootloader mode where you will only see the text on the screen. Now you use
      Code: 
      fastboot oem unlock-go
      to unlock. This will factory reset your device
    5. Setup the tablet again, enable USB debugging, and reboot again to the bootloader
    6. Download tbx304-twrp-3.4.0-20201207.img (TWRP) from the OP
    7. Then run
      Code: 
      fastboot boot tbx304-twrp-3.4.0-20201207.img
      to temporarily boot into TWRP.
    8. Select to keep system read only when TWRP starts to avoid modification which will make OTAs impossible
    9. In TWRP, go to WIPE, click on "Format Data" in the lower right, and follow the instructions.
    10. Go back to the TWRP home screen, choose "Reboot", and click "Recovery"
    11. In TWRP, go to the Backup tab, and backup the boot, recovery, and system image. Keep this backup for OTA updates.
    12. Go back to the TWRP home screen, hit the reboot button in TWRP, and choose "Bootloader".
    13. Then run
      Code: 
      fastboot flash recovery tbx304-twrp-3.4.0-20201207.img
      to permanently install TWRP.
    14. Once installed, press the volume button until it says "Recovery Mode" in red letters on the top, then hit the power button to boot back into TWRP.
    15. Load the LineageOS zip file from your computer onto the tabled by using
      Code: 
      adb push [NAME_OF_LINEAGE_ZIP_FILE] /sdcard/
      . If you are going to install gapps (Google Play Store, etc.), download it from here and push it to the tablet the same way
    16. From the TWRP home screen, go to Install and install the LineageOS zip file. Once that is completed, repeat the process to install gapps, if you're using them.
    17. Select the option to reboot. If everything worked correctly, it should boot into LineageOS.

    Thanks for the great ROM! It works well on my Tab 4 10 X304L. The only thing I have trouble with is that I can't get safetynet to pass and Netflix can't be installed. Otherwise, it's running pretty well.

    Solve Safetynet issue:

    2. Install MagiskHide Props
    3. After install MagiskHide and reboot
    4. Install any terminal emulator from the PlayStore/F-Droid
