Updating the Firmware in Uniden DMA Scanners
From The RadioReference Wiki

Please use this article to document issues, problems and resolutions regarding updating the firmware in the Uniden DMA scanners. In general 2 rules seem to apply;
- NEVER skip any steps in the process, regardless of how convoluted it seems
- ALWAYS use the AC adapter (best) or a freshly recharged set of batteries when applying the firmware. Low voltages can corrupt the process.
The database says my system has been rebanded. What do I need to do to trunk this system correctly?
- If the system is a Motorola type, you will need to get a new scanner if it's older than the BC296 or BC796. Uniden did not issue firmware updates for the BC245, 895, 780, 250, 785 (Firmware fixes are available for the BCT8). If you haven't applied the firmware fixes, see the next question.
- EDACS type systems will only need to be reprogrammed with the new rebanded frequencies. No firmware fixes are required to track these systems.
What are the most current firmware releases for the trunktracking radios?
- Rebanding support started with version 3 of the firmware; additional point releases refined it. It's recommended that you have the latest firmware available
- These scanners came with rebanding support already installed but there may have been additional tweaks in other firmware releases
Where do I get the firmware updates for my scanner? How do I apply them?
- All the firmware updates, with instructions, are now linked on the Uniden wiki manuals article
