So, finally i was able to unlock the bootloader using the firehose file from the stock rom and editing the devinfo.img..
I will make a detailed guide soon, so that others can make use of it.

EDIT: Detailed thread HERE

Thanks....

Hey but the bootloader is unlocked right so why does that matter? I think it happens to every tab after unlocking the bootloader the oem unlocking option gets greyed right?
So we can go ahead and install twrp and rom without worrying about the oem unlocking greyed right?

It's for people who can't unlock bootloader, since OEM unlock is greyed out

lineage-16.0-20210515-UNOFFICIAL-TBX304.zip
latest build available with the May 2021 security patch.

The sources used were the one provided on page 1 based on Lenovo-devs work.

All I did was sync the repo and build - the latest security patch was added by the LOS team.

Hope this helps,

good morning

I'm about to venture to change the stock rom of my X304F for the LOS 16.0 rom.

Specifically, if I am on Android 8.1.0, I would have to put only these 2 things:

1.- twrp-3.4.0-20210407
2.- lineage-16.0-20210515-UNOFFICIAL-TBX304

correct??

Would I need to reset the factory to bring it to 7.1 ??

I hope you can support me with the information, in advance thank you very much for your time.

    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.

    Have you got anywhere with this? I have exact same issue you have on X304F and I am very unsure why and if it could possibly be fixed. I'll be very sad if I cannot make this work.... Love LOS....

    Please let me know.

    Regards,

    EDIT1:     From what I am reading in this thread, it would look like this LOS package would be actually intended for the L version and not working properly on the F version, both of them probably sharing some but not all hardware.
    I am unsure but It would like screen might be different hardware, maybe even resolution.
    I had the same problem using the TWRP version provided without the 'F' at the end (just x304 no letter) and touch was not aligned right.
    Now could this be fixed easily? I dont know of LOS enough to tell that, maybe someone do? @highwaystar_ru ?
    I'd be more than happy to test on my device or provide data which could help fix the ROM for the F device.

    Could you please test this TWRP build https://cloud.mail.ru/public/AU29/uv1CLEfEs

    x304 source code really helps, fixed fast charger and fixed some code in touchscreen driver. Please check if test twrp fixes touchsreen issue. Lineage 17.1 with updated kernel is on the way.

    I dont get it, why arent you switching to android Q then? Its higher android version right? Or am i not getting somthing?

    Well moving to latest version available is not always the wisest thing to do. Things that worked for you may end up not working anymore (let's say you use a specific app which does not have an update for Q yet), even more for old devices which were not really designed to support such a new release (some drivers may be missing or not updated and such). New versions of OS usually need more Ram to function, leaving you will less Ram for you to use, and again that can be a problem.
    As goes the famous saying : 'When it works, don't fix it' ;)

    However you are right at some point you have no other choice but to update, even if that comes with a tradeoff. For example once NetFlix (or any of the few other apps I want to keep using) will drop P support, I wont have a choice but to move. But I still have time. But at the moment there is no appealing feature on Q which makes me want to update unconditionally.

    At the time being, I am just happy with applying google security patches every now and then. Probably more often as soon as I can figure out how to build for multiple devices on same LOS version.

    Cheers!
