Upgrading ROMS
enable Developer options: Settings – > Click on the ‘About Phone’ option and tap on the build number seven times to enable developer options.
Go back to the Main Settings menu, open Developer Options.
Under Debugging set Android debugging / ADB debugging to ON.
Download TWRP (the .tar!) - NB read the ODIN Install method
Download ODIN
Reboot the device into Download mode
Use the AP button in ODIN to flash TWRP
Reboot the device into Recovery mode - you should see TWRP.
Wipe Data
Download ROM
Download Gapps (ARM / Android 10)
Copy ROM + Gapps to device
Install ROM (still in TWRP)
Install GApps (still in TWRP)
Reboot
First boot will take a LONG time! And during setup it rebooted twice for me.
Optional: Root it
Download magisk.apk, rename to zip, copy to device, reboot into recovery / TWRP mode and install the file
I know it's not the recommended way but the "proper" way doesn't generate a tar file, so ODIN can't use it.
Note on LineageOS:
settings -> system -> Status bar -> quick pulldown allows you to get a shortcut to the settings quickly
ROMS
[1] Lineage OS 17.1
Old information
LineageOS 14.1 Klimtwifi Android 7.1.2 build 9/12/18
[ROM[UNOFFICIAL][7.1.2] LineageOS 14.1 SM-T700] Thread
Last update Deathly version or Vanilla version
difference deathly and vanilla
1. Exynos5420 builds feature Deathly kernel by @deadman96385 It is a feature-rich kernel with patches like UKMS, GPU volt control, CPU overclock etc. However it is not very stable compared to the LineageOS kernel used in official builds and my builds linked.
2. Exynos5420 builds add Deathly Adiutor and LineageOMS to the source tree. This allows theming support with Substratum. LineageOS builds lack this functionality, per LineageOS charter.

Apps
- Battery charge limit
This app by SL/\SH requires root, but because I usually have this tablet on a charger I like setting it to discharge until 60% and then stop charging at 80%.
