1. In mass-produced transceivers, the initial firmware update process occurs via the JTAG interface. This takes much less time and doesn't require a serial interface.
2. The cable with the CH340 chip works correctly with the original Baofeng bootloader and CPS, but is unable to work with the HR_C7000 internal bootloader. I tested several cable revisions with different circuitry (with and without a quartz crystal, with and without additional transistors, with different TTL levels). In my case, none of the versions could access the HR_C7000 internal bootloader.
3. The cable with the FTDI chip works without problems with the HR_C7000 internal bootloader, but has problems reading the codeplugs in the CPS.
4. Testing was conducted on Windows 10 and 11 operating systems.
Summary of the above: The cable on the FTDI chip may be needed only for obtaining backup copies of flash memory, and the cable on the CH340 chip is used for basic work with updating firmware and writing/reading codeplugs.

вот только зачем ты от UV-32 прошил? У них даже ориентация экрана разная.
