TWRP is a custom recovery and if you install it on your Samsung Galaxy Tab S7 FE, you will be able to install custom firmware or third party software that is not easily installable. This includes custom kernel that would let you overclock Tab S7 FE among other capabilities.
The one available for Galaxy Tab S7 FE is an experimental build and was only tested on the 4G LTE variant bearing model number SM-T735.
When tested on our Tab, we noticed that the status bar does not update. Also, once you’ve the TWRP installed on Tab S7 FE, you cannot access data partition as it is still encrypted. In case you are using multi disabler, do not format the android tablet as it may not boot. Before installing TWRP on S7 FE, make sure you’ve backed up your data and there is a slight chance your tab may not even boot up as everything is in sort-of alpha stage.
To flash it, head over this GitHub page and compile the TWRP. You will need minimal manifest files to compile it. Also, this must be done in Linux. There is no pre-compiled version available.
