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). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
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.
