Samsung Galaxy Tab S10 FE+ (SM-X620) Firmware

Samsung Galaxy Tab S10 FE+ (SM-X620) Firmware Overview

What is the latest SM-X620 firmware?

X620XXUBDZJA, released October 27, 2026 with Android 17. It is a feature update on bootloader binary 11. The archive holds 47 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.

Is the Samsung Galaxy Tab S10 FE+ still getting updates?

Yes. The newest build is from October 2026, and 1 of 20 regions already have a build from that month; the rest usually follow within a few weeks.

Which Android versions did it get?

The SM-X620 builds in the archive run Android 16 to 17. The earliest build we have for each version:

• Android 17: X620XXUBDZJA (Oct 2026), 1 build in total
• Android 16: X620XXS8CZF2 (Jun 2026), 46 builds in total

Can I downgrade the SM-X620 firmware?

Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 11:

• Binary 11 — since Sep 2026
• Binary 10 — since Aug 2026
• Binary 9 — since Jul 2026
• Binary 8 — since Jun 2026

A phone already on binary 11 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 11 build. How to read a build number.
