Uniden SDS100 firmware 1.05.00 main / 1.01.05 sub (open beta)
=============================================================

WHAT THIS IS
Open-beta main firmware 1.05.00 with sub 1.01.05, posted on 27 July 2018. It
fixed Site NAC operation for compared NACs and digital end-code detection on
Motorola systems, modified P25 Phase 1 voice-channel termination, and
introduced the Site NAC Operation setting.

IMPORTANT: BETA - superseded. Posted by Uniden (forum user UPMan) in a
RadioReference open-beta thread; kept for the record. A scanner should run the
current public release via Sentinel.

This is BETA firmware from 2018-2019. Uniden hosted it in the "PartnerWeb"
area of its support wiki and announced it in RadioReference open-beta threads.
It is superseded and is kept for the record only.

APPLIES TO
The Uniden SDS100 (US model) only. Not for the SDS100E/SDS200E, SDS150,
BCD436HP or BCD536HP.

BEFORE STARTING
  - A Windows PC and the scanner's USB cable (SDS100: mini-USB port on the
    side; SDS200: mini-USB port on the front).
  - A backup of the whole microSD card and of the Favorites Lists (Sentinel).
  - SDS100: a charged battery. SDS200: the power supply connected.

CONTENTS OF THIS ZIP
The download zip holds the vendor file exactly as Uniden published it, plus
this README.txt and SHA256SUMS.

INSTALLATION
Uniden's beta posts gave only brief steps ("copy the appropriate file ... to
the firmware folder of your scanner and reboot"); the fuller steps below
follow Uniden's later manual-install readmes for the same scanners.

  1. Connect the scanner and choose Mass Storage (press E at "Select USB
     mode").
  2. Open the removable disk, then BCDx36HP -> firmware. Leave the two .dat
     files alone.
  3. Copy SDS-100_V1_05_00.bin and SDS-100-SUB_V1_01_05.firm into the
     "firmware" folder.
  4. Restart the scanner; it applies the update while booting. Do not
     interrupt it.

VERIFYING
Menu -> Settings -> See Scanner Information -> Firmware Version.

IF SOMETHING GOES WRONG
  - Beta firmware was issued for testing and carries no support. Return to a
    public release with Sentinel -> UPDATE -> Update Firmware.
  - If the scanner will not start properly after files were removed from the
    "firmware" folder, Sentinel -> Clear User Data rebuilds the card (erasing
    user data).

DOWNGRADING
Moving back to an older public build by hand uses the same copy-and-restart
method with that build's files. Sentinel always installs the newest release.
