Do not attempt this with a drained battery. The flash process takes 12 minutes. If power fails at 50%, the radio becomes a "brick" (unresponsive black screen). Use a fully charged IMPRES battery or an AC eliminator.
Near the end of production, Motorola released a "beta" branch for specific federal clients. These versions are notorious for crashing CPS. unless you have a specific hardware variant that demands it.
The key takeaways for anyone working with XTS5000 firmware:
Ensure a stable power source (charged battery or battery eliminator) as a power failure during the flash will likely kill the radio. Critical Features Controlled by Firmware Firmware & Flashcode Update for XTS Radios
A fully charged OEM battery, or ideally, a stable battery eliminator connected to a bench power supply.
You need a programming cable , a PC with ASTRO 25 Portable CPS (typically version R20.01.00), and the firmware files.
Genuine Motorola firmware upgrade files are distributed as .cvn (Customer Version Number) files. These files contain complete instructions for updating the host, DSP, and optionally the UCM. Some community sources distribute .bin files from other radio families, but these are not directly compatible with XTS5000 firmware procedures.
