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,
