Hello. This is my first ever post on XDA, so please excuse any mistakes. Recently, I have been wanting to install TWRP on my Samsung Galaxy Tab S7 (Model Codename: SM-T870), however, I haven't found any .img files available, either official or unofficial. I have been able to root it using Magisk and Odin, however. My tablet is currently running Android 11 with a build number of RP1A.200720.012.T870XXU2BUC6. From what I've read online, the "2" in the "T870XXU2BUC6" section of the build number means that the Bootloader is on Version 2, meaning that I can't downgrade to software versions with a 1 in the software name (i.e. with a Bootloader version of 1). This includes Android 10, and some older versions of Android 11, even if I use the latest version of Odin and if I'm rooted. I know how to install different distros and versions of Linux for creating TWRP from scratch if need be. If someone would be willing to either guide me through the process of creating TWRP for this device, or include a link to an already existing version of TWRP for this device (remember, Android 11, Build Number: "RP1A.200720.012.T870XXU2BUC"), I would greatly appreciate it. All I ask is that the guide(s)/tutorial(s) be in layman's terms, and be step-by-step. I am not very familiar with Linux Commands, so I would appreciate some grace when replying to this post, as I may not be able to understand some terms. Thanks!
