Uniden SDS100/SDS200 firmware 1.09.00 main (open beta)
======================================================
WHAT THIS IS
Open-beta main firmware 1.09.00 for both the SDS100 and SDS200, posted on 20
March 2019. It targeted 5-second mutes caused by false digital detection on
analog Motorola trunk channels and on EDACS/LTR, and crackle noise with CTCSS;
extra logging was added.
IMPORTANT: BETA - superseded.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It is superseded and is kept for the record only.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 and SDS200 (US models): the zip holds a separate file for
each; copy only the one whose name matches the scanner. 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

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 the file for the model (SDS-100_... for the SDS100, SDS200_... for
the SDS200) into the "firmware" folder - one file only.
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.
