Samsung Galaxy Folder (SM-G155S) Firmware Overview
What is the latest SM-G155S firmware?
G155SKSU1APL2, released January 12, 2017 with Android 5.1.1. It is a feature update on bootloader binary 1. The archive holds 8 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Folder still getting updates?
Most likely not: there has been no new firmware since January 2017, 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-G155S firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 1:
- Binary 1 — since Sep 2015
