Hi,

since @codeworkx provided a build for February I initially hadn't planned to upload one of my builds. But because in at least some cases problems occurred with the new build I now uploaded a build of mine that includes the February 2022 security patches to AndroidFileHost. It should be possible to dirty flash the ROM over the existing LOS 17.1 build from codeworkx or me, which I again did successfully some days ago.

Not sure, but can you try setting a different PIN, like 0000, and afterwards do the factory reset?

it was a great rom. my new P11 tablet with all the preinstalled crap doesn't feel that much faster. if the tab2 10 has a better screen i woulda kept it.

Hi,

I just uploaded a new build that includes the April 2022 security patches to AndroidFileHost. It should be possible to dirty flash the ROM over the existing LOS 17.1 build from codeworkx or me, which I again just did successfully.

Thanks Ecthelion4 for regularly updating the LOS 17.1 ROM!👍

I would like to inform you that I had installed the April build of the LOS 18.1 ROM to my Tab4 10 Plus, TB-x704A. The build is very stable to use as the daily driver. I think we can move on to the LOS 18.1 ROM.

Please suggest any Dolby Atmos mods that work with LOS 17.1 and LOS 18.1 ROM.

Regards,

Thanks for the information. I'll see whether I can set up the LOS 18.1 build for the Tab 4 10 Plus. If I can get it working and the resulting image is working fine on my device then I'll switch to the more recent 18.1 codeline. Please give me some time, though. At least the May security will most likely still be for LOS 17.1.

Thank you for your consideration.
Looking forward to seeing your hard works in the near future.

Thank you for your consideration.
Looking forward to seeing your hard works in the near future.
Some months ago I had set up a VM for building LOS 18.1 for the Tab 4 10 Plus. I now tried updating the code and then building the stuff again, but I'm now getting error messages I don't understand. So it looks like someone else having to provide the 18.1 builds. I can continue with the 17.1 until someone steps up and regularly provides builds for LOS 18.1 (or even 19). Sorry

    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.

    Code:
    #include 
    /*
     * Your warranty is now void.
     *
     * I am not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * 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.
     *
     */

    Here we go again, after building LOS 17.1 last weekend, it's LOS 18.1 this weekend. Thinking back, Lenovo didn't release a single major update for this device.

    From very brief testing, I can say that the camera and fingerprint scanner do not work. I will test the new OS in detail in the next few days and then create a separate thread soon.
