MinsOS — Galaxy Tab S7 11" LTE (SM-T875 / gts7l)

One UI 8.0 (Android 16) for a tablet Samsung stopped at Android 13.

SM-T875 only. Not the Wi-Fi T870, not the 12.4" models, not the 5G T878U, not the S7 FE. Check Settings → About tablet → Model number first: the kernel here carries only this model's device-tree overlays, and the installer refuses anything else.

Status: nobody has booted this

Read that line again before you download. Everything that can be checked without the hardware has been checked; that a T875 starts up is not one of those things. This is published because an owner cannot test what is not published, not because it is known to work. If you flash it, you are the first - have Odin and your stock firmware ready before you begin.

What was verified, and how:

• Built from SM-T875's own firmware. Every device-specific input - vendor VINTF, floating-feature values, the SIOP thermal policy, the kernel machine config and its device-tree overlays - comes from T875 stock rather than from the 11-inch Wi-Fi tree. Copying that directory from another model is what bootlooped every T870 on its first build, so it is checked rather than assumed: the vendor manifest that ships is a superset of T875's own.
• The kernel carries this device's board id, and its configuration was read back out of the built image rather than trusted from the build log.
• Clean build, so the patch baseline is real: every patch this ROM depends on applied, and not one warning signature is unique to this device - the set is a subset of the three shipping models.

What is not verified: that it boots, that the panel comes up, that touch and Wi-Fi work. That is the entire list, and it is why this folder is separate from the tested ones.

Cellular does not work and is not planned. The system half comes from a Wi-Fi-only Tab S9+, so the SIM is detected and the phone app errors; removing the SIM stops the message. You get a tablet.

Coming from stock? Flash vbmeta_disabled_T875_DXH2.tar in Odin's AP slot first. Our zip does not write vbmeta, so a stock tablet keeps Samsung's, which then refuses our dtbo with "Error verifying vbmeta image: invalid vbmeta header (6)" after the ROM is already installed.

If it fails to boot, before flashing anything else pull /sys/fs/pstore/ from TWRP over adb and report how far it got - Samsung logo, boot animation, or setup wizard. That report is worth more than the build is.

Latest — v0.3.4

First SM-T875 build. Not booted by anyone yet.

Check the download before you flash it. A truncated 5.8 GB file sideloads for twenty minutes and then fails:

sha256sum -c MinsOS_v0.3.4_20260805_gts7l.zip.sha256

Before you flash

• This wipes your data on a first install. Updating from a previous MinsOS does not.
• Unlocking the bootloader permanently trips Knox. Samsung Pay, Secure Folder and the warranty are gone for good.
• The ROM is pre-rooted and you cannot opt out. It ships the KernelSU-Next kernel and the manager app together; the manager installs itself on first boot. Do not flash a kernel afterwards — that unpairs them and root silently stops working.
• Expect attestation-sensitive apps to behave differently than on stock.

Install

TWRP → Wipe → Format Data (first install only) → Advanced → ADB Sideload → adb sideload MinsOS_v0.3.4_20260805_gts7l.zip → reboot. Wait until adb devices reports sideload before transferring; starting early sends zero bytes and still looks like it worked.

If a root manager says "not supported" after flashing, check which app you opened: an old me.weishu.kernelsu survives the flash and is a different app from com.rifsxd.ksunext.
