Samsung Galaxy J1 mini (SM-J105B) Firmware Overview
What is the latest SM-J105B firmware?
J105BUBS0ASB1, released April 4, 2019 with Android 5.1.1. It is a security update on bootloader binary 0. The archive holds 20 official builds across 15 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J1 mini still getting updates?
Most likely not: there has been no new firmware since April 2019, so Android 5.1.1 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-J105B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 0:
- Binary 0 — since Jan 2016
