Read verified
PocketCHIRP has successfully read a UV-K5 running F4HWN custom firmware using the firmware-aware programming workflow.

Writing back to the radio has also been proven, making this a verified two-way programming path rather than an experimental profile.
Program F4HWN custom firmware from Android
F4HWN is part of the active Quansheng UV-K5 custom-firmware ecosystem. PocketCHIRP treats custom-firmware variants deliberately instead of assuming every UV-K5 memory image and identification path is identical to stock firmware.
Bluetooth programming is proven
PocketCHIRP testing has successfully used a Baofeng Writer Bluetooth programmer with the UV-K5 custom-firmware programming path. That gives F4HWN users a practical cable-free option for reading and writing radio configuration from Android.
Why firmware-aware drivers matter
Custom firmware can change identification, memory interpretation, available settings, or other behavior even when the underlying radio hardware is the same. PocketCHIRP keeps firmware-specific support explicit so a successful connection does not become a misleading claim that every UV-K5 firmware variant is interchangeable.
Other UV-K5 custom firmware
PocketCHIRP also has dedicated, verified support pages for VUURWERK and IJV_V3. This growing custom-firmware support is one of the areas where PocketCHIRP extends Android radio programming beyond a generic stock-radio workflow.
