I've tried, but it seems I don't know how to do it.

1. Turn OFF radio
2. Press key Open Serial
3. Turn ON radio
4. If you did everything correctly, you will see HDBoot in the status bar.

Interesting. So how is this backup made? Is it through the normal CPS, or would I need a special software?

Use OpenUV008_Flasher or Dahua SOC Tools

I've tried, but it seems I don't know how to do it.
I opened the app, set the correct COM port, then enabled (?) the Debug Mode button, then pressed on Memory. (I've left other things alone, like "Target" in DH5000 setting)
After that, I set "TargetAddr" to 03000000 and "TargetLen" to 262144. I then pressed "Dump Mem", gave a filename, but after a short while it says "Dump Mem Error!" I tried doing it with the radio in normal mode and in DFU mode, to no avail.

I figured out how firmware protection is implemented in the Baofeng DM-32. The ALPU-MP chip, connected to the processor's I2C bus, protects the firmware from unauthorized copying and use. The private key is stored in flash memory; if the flash memory is damaged or a memory image from another radio is used, the radio will not function correctly! The backup flash memory will only work with the radio from which the image was obtained! Currently, I cannot bypass this protection...
If anyone is planning to experiment with firmware, be sure to have a backup copy of your radio's flash memory!!!





In the attachment, exchange via the CPU<-> ALPU-MP and datasheet

MGayR7, Can you open the radio and see the chip number?

I can only assume that the radio's software compares the flash memory contents with the processor ID and, if there's a mismatch, displays a message about invalid hardware. This is just me thinking out loud...

I need to think...
