Radio amateurs and GMRS operators often need wideband (25 kHz) capability. This presents challenges with later CPS versions. Many users report that was the last legitimate release allowing wideband programming on CP200 radios without requiring entitlement keys or software modifications.
Before attempting to use RVN4191, you must ensure your radio hardware is compatible. Using the wrong software version can result in communication errors or corrupted codeplugs. RVN4191 is primarily engineered to support the following Motorola models: Portable Radios CP150, CP200, CP200XLS PR Series: PR400 EP Series: EP450 ( regional variants) Mobile Radios CM Series: CM200, CM300 PM Series: PM400 Key Features and Capabilities

In bypassing the checksum mismatch, it had allowed a slightly incompatible codeplug to write to the radio’s secure memory segment. The radios were not just programmed—they were slowly dying. One by one, over the next year, all forty-seven radios would throw the FAIL 01/82 error. The county would have to buy new radios anyway.
Follow this standard workflow to read and write configuration data safely. 1. Reading the Radio (Backing Up)
