Code:
/*
 * I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...). 
 * Please do some research if you have any concerns about features included in the products you find here 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. 
 * Your warranty will be void if you tamper with any part of your device / software.
 * Same statement for XDA.
 */

LineageOS is a free, community built, aftermarket firmware distribution of Android 10, 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.

How to install
You have to had TWRP installed from this thread TWRP and ROOT for Tab 4 8/10 (Plus) (TB-8704X/F/V,TB-X704L/F, TB-8504X/F, TB-X304L/F)

In TWRP clean Data if you coming from stock ROM and do Install of this ROM. If you have android 8 stock rom installed you have to format Data with data loss, because used encryption is incompatible with android 7.1

TB-8704V (Verizon)
If you have TB-8704V tablet, you have to additionaly flash boot.img from link above after rom intsallation. This tablet has some hardware differences from x and f and requires custom kernel to work,

Thanks
Big thank to @mistersixt, who donated $$ for device.

What are the install steps if I have lineage 16 already installed. i.e. sufficient to use the existing TWRP. Can I have Dirty flash? etc

Full wipe and reinstall for a major version number release like this, I believe. Dirty flash will almost certainly fail. Your existing TWRP should suffice, but you'll need to reflash gapps when you install los17.1

So far, working very well. No crashes or hangs, everything fast and smooth. Two things that don't work are DT2W but this was already known. The other is USB hubs do not work at all. They do not work on LOS 16 either but they do work on LOS14. A fix for this would be greatly appreciated.

Great work other than that as usual highwaystar.

Yes all lineage-17.1 branches. In latest built these lines are removed to make it bootable on wifi version https://github.com/lenovo-devs/andr.../lineage-17.0/prebuilt/bin/deunify.sh#L16-L30

I just did a clean install of the latest version (lineage-17.1-20200601-UNOFFICIAL-TB8704.zip) and noted that, although I'm on tb8704f, I can still see the "Messaging" app, which wasn't there when I wasn on 16. Looking at the code highlighted in the github link above I wouldn't expect to see Messaging on my device. I was also asked if I wanted to configure a SIM during the first boot and setup.

I rebooted to TWRP, wiped Dalvik, system, data and cache, pushed lineageos and opengapp (full) zips, then installed and rebooted.

In fixed 20200601 fix is to *not* remove telephony and messaging apps.
