Public-beta main firmware 1.06.00 with sub 1.01.05, posted on 28 September 2018. It fixed a freeze with more than 1,000 recording sessions, added Capacity Max late-entry decoding, modified the Capacity Max LCN Finder and changed DMR TGID validation - the same notes that later appeared under public release 1.07.00 (24 January 2019).

Read before installing. BETA - superseded.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.

Uniden SDS100 firmware 1.06.00 main / 1.01.05 sub (public beta)
===============================================================

WHAT THIS IS
Public-beta main firmware 1.06.00 with sub 1.01.05, posted on 28 September
2018. It fixed a freeze with more than 1,000 recording sessions, added
Capacity Max late-entry decoding, modified the Capacity Max LCN Finder and
changed DMR TGID validation - the same notes that later appeared under public
release 1.07.00 (24 January 2019).

IMPORTANT: BETA - superseded.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It is superseded and is kept for the record only.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.

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_06_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.
