If you try to flash modified firmware on UV-K6, UV-K5(8) or UV-5R Plus with official FW update utility then below error will occur:

It will happens always when trying to "cross-flash" firmware from one radio model to another even the radios are 100% compatible.

To fix this you have (only once) flash firmware which will change your version:

• on UV-K6 or UV-K5(8) flash file: k5_v2.01.27_flashable_on_v3.bin
• on UV-5R Plus flash file: k5_v2.01.27_flashable_on_v4.bin

These are unmodified stock firmware from radio but version information is overwritten d so it will allow to flash it by official firmware update utility.
