Hi there,

i am kinda new to this. But i keep reading about the recommendations to upgrade the hardware on china clone units.
Like the crystal and capacitors and such. Am I understanding this right? Those changes would make the actual
function of the unit more reliable? Or is this a prerequisite for flashing the mcu?

As to flashing the mcu: I would need the firmware and the .lib file which must match, as well as some sort of
jtag-hardware plus the a programming software i.e. Ponyprg that can handle the mcu type. And the existing
At88 should not even be tried to be read, because that would already change its content. Did I get this about right?

Is there more to know which I didn't catch?

you got it right yes
do not in any way or reason try to read at88c (there is no reason to touch this ic)
leave it well alone dont even remove it
pcb modifications/rework is to help make the carprog more stable.

I have saw your post but want to check that file is it real or just changed serial number .I have saw many bin files which is actually fake and fake lib file too. I think posted files which is just renamed (lib files ) and changed serial in the bin files can't work properly even offline

you could buy any version because when you do they all need rework
ie caps wrong way round or missing completly etc
and most out there are only fw4
if you want latest version with less work needed then go for the 8.21 version only
this will save you having to reflash it but you will still have to check and see if everything on the pcb is correct
all other version for sale is really with fw4 (so if you see v9.31 etc it will really have only fw4 and lib for version 4.01 sw)

Thanks Tango My Friend, I have looked at the prices, 8.21 are Much more expensive, what is your advice ?
it is worht to buy v9.31 and rework it or buy just 8.21 ?
