Hoping someone can help:
Installed latest twrp and LOS 19.1 all went well, cool and smooth.
Closed cover. opened cover and blank screen.
Will (adb) reboot to OS, to recovery and to fastboot but no screen, no logo, no usual "warning". I've backed up. wiped and flashed (sideloaded) LOS 18.1, boots but still no screen.
Update: the screen works but no light! (I can see a shadow of the lineago startup screen
Are there ways to check/adjust screen brightness from adb?
Any ideas to get screen light working? or is it stuffed

Mine just did this, scroll up a bit :/ I ended up buying another. I feel like it's a hall sensor that's stuck or something, every once in a while with the right reboot combo it would come back to life but got steadily worse

Thanks. Most annoying. A trick I've just discovered (whether it will contine to work is another thing!) is that if I put the screen cover behind the unit, the screen light comes on. Almost as if the hall-effect switch is switched on when the magnet is reversed?

Huh. I have both first party accessories but not this one. Might be worth trying just to see if it revives the old one I have haha. Is that the exact one you have?
I believe it is, I bought mine many years ago. I also did a clean install of 18.1 boot, followed "start up" connected to wifi, then dirty flash of 19.1. Boot, flipped cover to behind and viola. It might work by placing a magnet on the back of the unit just to see if it is the hall effect switch?
Update: Started having the light not work again. A "fix" was to close the cover, press power button once and open, light on. Had to do it a couple of times to make sure. That seems to be the work around.
Have fun :)

lineage-19.1 - June 2022

Due to the upcoming holiday season the July build will be delayed or skipped ..

lineage-19.1-20220615-UNOFFICIAL-dragon.zip

Changes:
- Google security updates -> June 2022
- Patched system/netd to bring back Network traffic monitoring on older kernels.
- Patched frameworks/base & Permissions to support microG
- Latest LineageOS changes

As SDK level increased to version 32 we have to use new gapps for Android 12L.
Pls check latest gapps builds here ..
https://drive.google.com/drive/folders/1O-I01LDvno57ztnxIW_bSnVWEk8-6Ics
Thanks to @ipdev for the opengapps packages !

Tested with Magisk 25.0 !

Enjoy Android 12L (y)
Thanks for your efforts on this! Dumb noob question: after the install, do I just live with the message at bootup: "Bootloader Unlocked / OS Verification Off / Device will continue booting in 30 seconds" or is there a way to bypass that message or relock the bootloader? I did some searches on XDA and found a few custom mods to lock the bootloader (on different devices) but it looks pretty complicated. Just want to make sure I'm not missing some obvious thing, like "fastboot oem lock"! ;)
Thanks again!

Yes :-( I've been just living with it for a while and wasn't able to find a way not to (without dying, of course) :)

Thank you for this ROM. Nice to enjoy 12 on our now old devices. Followed the procedure to flash, all went well.

After a few weeks of use, my device becomes unresponsive when it wakes from sleep.it takes a good 5 to 10 minutes t become usable. Anybody else has this issue? or maybe my device has some hardware issues?

Thanks again for this ROM.

I flashed the latest 19.1 system, connected to the computer after booting it up, and there was no response when I selected file transfer, so I couldn't connect to the computer. What happened? This is the case after re-flashing the system several times. How to solve it, I have to flash back to the official system. Have the same problem?

I had similar issue after flashing an older version and was never ever to get it recognized. Was not eve able to flash magisk so i'm stuck on stock LOS. One day when I have the time, my hope is to upgrade it and get it communicating with the PC again.

Update: Didn't fix my original issue, but I like the case! Keeping it for simplicity.

If I am reading your posts correctly.

You are having issues with MTP (Media Transfer Protocol) when booted into system?
- What OS (Windows, MacOS, Linux)?

If you are referring to adb/fastboot, what release of platform-tools are you using?
- The newer versions seem to have some issues with (the chromeOS parts of) dragon.

Note:
Platform-Tools r27.0.1 (December 2017) seemed to be the safest to use at the moment.
You can download an older release of platform-tools by adjusting the official download link to the release you want.

Cheers. :cowboy:

    I'm a software developer who is new to Android OS development. In my career I learned you should have two important things, a great machine and teacher. I got both

    First, thanks a lot for bringing new life into this old tablet!
    When using the physical keyboard with Norwegian layout I'm missing the letter Å. The rest of the special Norwegian characters are present, but the \ is where the letter Å should be. Using enhanced ASCII code doesn't work either. Does anybody know of a fix or work around? I could have the software keyboard on the screen while typing, but it takes up a lot of screen space. Any suggestions are highly appreciated!

    Edit: I'm on the latest LineageOS build downloaded from the first post in this thread. The letter Å is supposed to be where the + and = is located.

    Edit 2:
    Seems like the Swedish and Danish keyboard setup has the same bug.
    Quoting myself as I found a sokution to the problem.
    I had to find the specific key layout file for the Pixel C keyboard, as editing the Generic.kl file in /system/usr/keylayout/ did not work. The Pixel C keyboard file is named Vendor_18d1_Product_5018.kl. I changed th EQUALS key to Å and chose Norwegian as keyboard language. The only thing missing now is the apostrophe key, still trying to figure that out.

    Hi!
    USB file transfer doesn't seem to work for me. Tried different ports or different cables. Has anyone tested it?
    Mine hasn't worked for years now. I gave up and have to download everything to the tablet.
    But for me it was working well in previous versions.
    Are you referring to adb command(s) like adb push or connecting using a file manager (MTP connection) to copy files between the device and computer?
    MTP is currently broken in TWRP for dragon..

    Are you using Linux, MacOS or Windows to connect?
    MacOS needs a third-party app to connect via MTP.
    - Unless they updated something recently, I haven't booted up MacOS in about two years.

    I have windows 11 and adb commands work when I get the tablet recognized, just no file transfer either when the tablet is plugged in or when I am in TWRP and its plugged in. It just errors out the device driver every time. Fastboot it recognizes if I go manually select the driver after plugging it in.
