- Place our device firmware on SD and flash it using standart procedure or Flash firmware using autoexec.ash
- Reset.

different names
it just need to rename the firmware of our device to name that use device which .elf is flashed.
example names:
device | firmware name |
---|---|
Koonlung C75 | hd121_50.bin |
iReg-7570SHD | hd121_70.bin |
Carcam Smart | hd122_50.bin |
different magic numbers
that cause need of CRC and magic number hacking using hex editor
- our .bin file maybe updated to have alien magic numbers
- alien .elf file maybe updated to have our magic number (preferred)
As A result we will have something like
Firmware | URL |
---|---|
