Samsung SM-A102U1 Firmware Overview
What is the latest SM-A102U1 firmware?
A102U1UEUGCWH1, released August 29, 2023 with Android 11. It is a feature update on bootloader binary 16. The archive holds 20 official builds across 19 regions (CSC).
Is the Samsung SM-A102U1 still getting updates?
Most likely not: there has been no new firmware since August 2023, so Android 11 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-A102U1 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 15 to 16:
- Binary 16 — since Aug 2023
- Binary 15 — since Apr 2023
A phone already on binary 16 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 16 build. How to read a build number.
