Thank you for this ROM; it's pretty smooth much better than the stock ROM. I do have this problem with the camera suddenly stops but disabling it seems to fix the issue.

And it doesn't seem like I can access storage via USB connection; the storage on isn't showing despite the notification saying its transferring files.

I just wanna make sure I'm doing this right.

I flashed TWRP with ODIN
I am currently on build number T290XXU3BTI2 according to settings
That means I need to flash T290XXS3BTL6 (with ODIN) before installing the ROM zip with TWRP correct?

Great rom! I have one issue though when I plug in my wired headphones the audio plays through the speaker as well and wireless gives no audio at all. But everything else is really stable and I am loving it!

Can't set a lock screen PIN or pattern. How come? Seen a couple people mention it but no one providing a solution. Flashed stock 9 ROM and it works again. Then flashed this a second time - broken again.

    Not clear yet how I modify the custom ROM to address this, but a workaround is posted here.


    I have a suspicion that the cause isn't in the custom ROM, but elsewhere. I've encountered the same problem running the 10 stock ROM after TWRP was installed (haven't got around to flashing the custom ROM yet). In addition, the workaround isn't working for me. :(

    Installed the ROM last night and apart from a few minor niggles (mainly personal preference) it's going well. The main issue would be the lock screen, which we're already aware of. I almost never use MTP, so absence of that isn't a handicap.

    Many thanks!

    Yeah that work around didn't work for me. I've tried all sorts - but kinda given up having this tablet rooted. I need the lockscreen as it spends a lot of time in the car.

    I've played around with LineageOS 17.1, which is SELinux Enforcing, and still have the same inability to set a pin or password. I'm tending to think that the problem either lies in TWRP, or in something that TWRP upset when it was installed.

    At the moment, it's not a big issue, as I mostly have the tablet at home but if I started taking it out a lot, I would want a lock of some kind.

    I'm thinking about putting the stock ROM back on this so that I can have a lockscreen, but before I do that, I'd like to ask if there's been any progress/ideas etc on ways to work around what seems like a Samsung "feature" to discourage one from modding.

    (Though I'd have to say it reminds of "you won't play by my rules? :( Then I'm taking my ball away and going home!")

    Cool! Many thanks. I'll hang fire on any reversion to stock and see how this one goes. I can, if necessary, post adb logcat logs.

    And if it doesn't happen this weekend, I can wait for a few days. :)

      Just installed this, and it breathed new life into another wise, cruddy device...thank you for the work.

      Here's my first effort at porting the Nexus Stock custom ROM to the 2019 Galaxy Tab A 8.0 [SM-T290] on Android 10. It's very much a work in progress, but it should hopefully help blaze the trail for even better work.

      Notes:
      • The current process may require you to reset to factory defaults to remove file-based encryption. Remember to backup your data!
      • The system is based on @AndyYan's LineageOS 17.1 (LQ) with the latest Stock variant from OpenGApps.
      • Boot animation and default wallpaper is from my Nexus series of custom ROMs for Android TV, and I'm using the Pixel boot animation with black background.
      • This should be installed using my latest TWRP build for the SM-T290.
      • The properties now correctly identify the device as a tablet, and so the Google Dialer and Messenger are no longer installed. I've also disabled the Emergency button, but SetupWizard still insists on reminding you to insert a SIM (sigh!).
      • This is unofficial and unsupported, so the usual caveats apply. Since we don't mess with the bootloader, you should be able recover from any problems...but nothing is guaranteed.

      Not working:
      • Support for file-based encryption
      • MTP support (pending Samsung kernel source update)

      Note: If you install Google Recorder from the Google Play Store, it works just fine. The issue is with the pre-installed APK from OpenGApps.

      SafetyNet check failed (but basic is true). SafetyNet on stock firmware failed too, but MagiskHide always help. In your ROM, if i turn on MagiskHide, i got cyclyng reboot, over and over again until i turn "hide" off.
      SafetyNet fails by design on any device with an unlocked bootloader and custom ROM. Magisk has its tricks to try to fool SafetyNet, but it's a bit of Whack-a-Mole game.
      Can you make a custom Kernel with GPU Overclock? Tablet not so bad and run some games pretty well, with overclock they can be runs much better.
      Unfortunately, the Android 10 kernel source that was posted last week is not working. It compiles fine, but builds to a significantly different size and crashes to the bootloader when packaged in either boot or recovery images. Until that's addressed, I can't provide an MTP fix or any overclocking.

      Note: I just posted a v3.4.0-1 update to my TWRP for SM-T290 thread that includes a new custom T290UES3ATC1 kernel fixing MTP support. If you install it over the TWRP build included in this build, it will allow file transfers on this custom ROM by rebooting to recovery.

      Since this is an Android 10 custom ROM, I can't use it in the boot image, but it's a workaround until we get working T290XXU3BTI2 kernel source.

      Hi, there. I've managed to get the image installed, used the compatible version, etc. After rebooting, I got to TWRP, did the wipe, etc. Upon reboot, I get through to the setup process, skip the SIM setup stuff (no cell stuff in this T290) and then when trying to add a wifi connection, it never completes the "Connect to WiFi" step. If I skip, I can get through manual set up of the basics, manual time config, a few other prompts. All that seems okay. But even when I get to the main menu menu, it seems like everything is working (pulls up, etc) but I'm still not connected. The WiFi radio appears to be turned completely off. Each time I try to turn it back on, it flashes on for a split second, then immediately turns off again.

      Any ideas I can try to get this enabled?
      Okay, all weekend I've been trying to figure out why wireless isn't working on my custom kernel, but it appears the OEM kernel isn't working as well...and I didn't even realize it. This is actually a hugely valuable data point that will drive my troubleshooting in an entirely different direction.

      I'm embarrassed that I missed this in my initial smoke testing, but at least I know that my MTP fix is solid. More info to follow...
