[bonux]

Hello,
im looking for solution to recalibrate motorhours for belarus tractor, round cluster KD8083 made in belarus, inside it has PIC16F876A protected mcu, ive tried to read it with few programmers but its secured. Maybe someone have flash file for sale? or other solutions? thanks!

Hi,
"with few programmers" you can read ID PIC16F876A ?

[bonux]

Yes i can read id but no flash/eep

[ngt5]

I don't have CODE dump, only DATA dump. Code is locked :apologetic:

[bonux]

im not sure but i think you cannot write data dump (eep) without erasing code?

[ngt5]

Тhis is not so. For write data dump(eep), must erase only DATA.

[ngt5]

See this.Pass in PM

ok so after erasing only data and writing this file cluster is dead, no signs of life when vcc applied

This is 100% working dump in my units. May be your error is other.
