Bootloader 1.2 and 1.4 can be updated on versions of Xprog 5.0 to xprog 6.17
You just have to check
1.Bootlader
2.Firmware
3.Build
4.Link
the version is just 5.0 -5.55- 5.84-6.12-6.17 etc..
the Build remains I think it is with DONGLE and without DONGLE
also There is DB9 old USB and New USB
If someone wants🙂
he can read the Firmware of his Xprog 6.17 without Dongle
with USBASP or other interface to save for any useful purpose.
Compress the firmware and software to keep the original.
To confirm this backup another Xprog is necessary to fah with this backup
If someone loses their xprog while flashing
after being overwritten, just force a new flashing and repeat until recovery
