Uniden SDS100 firmware 1.26.01 (current; install with Sentinel)
Recommended version Not hosted — available from the manufacturer
The current firmware: main 1.26.01 (27 March 2026) with sub 1.03.15 (17 October 2025). 1.26.01 added a Type option to the P25 manual band plan and slot selection for DMR one-frequency trunking, improved Capacity Max late entry and Capacity Plus reception, updated DMR RAS handling, and fixed P25 Phase 2 staying on a voice channel with both slots filled.
Read before installing. Not hosted because Uniden has not published it as a file: current firmware is delivered only by Sentinel (UPDATE -> Update Firmware), which fetches it from Uniden's server. Install Sentinel 3.01.01 (hosted here) and run Update Firmware. Sub 1.03.15 is likewise Sentinel-only.
