UPA USB will program ATMEGA from VCDS cable without a problem.
Program eeprom
Program flash
Program Lock bits
Program Fuse bits and you are done.

Hello, I have always used this program.
USB jack connects to a computer powered obd socket (pin 4 pin 5 gnd 16 12volt)
and launches the program.

Hello,
I am trying to fix some old VAG COM 704.1 and a VAG COM 805 I got back from my customers.

I know what cables are really 704.1 between them, but I suspect someone gave me back a broken VAG COM 704.1 as he told me it was 805.

In the meantime I bought some 805.0, and then much more 805.1 which have a label on the plastic body, and the mainboard looks different. Much different.

So I have 3 types of board in front of me now !!! I am confused.

I look the 805 (or supposed to be 805) and looks different than my 805.1

So I am not sure if it's really 805.0, Is there any way to fnd what it could be with security?

Thanks

Hello,

from my experience and what I saw on internet, the baseboard has more-than-less same.. There is FTDI chip, ATMEGA162, CAN chip from Microchip and GAL from Atmel...

but anyway baseboard should looks different..

The issue with repairing cable is eeprom in the ATMEGA, FTDI EEPROM isn't point of intereset, because without correct contents in small eeprom in ATMEGA cable shouldn't works properly (for full access)..

This eeprom and firmware in ATMEGA are locked by LOCK bits for uC, so cannot be read back by programmer. Where china's guyes got firmware is strange for me...

Reading protected uC is not that hard with proper equipment:

Laser, microscope and acid will do the job.

What's the cloning method in china:

1- China buy original tool.
2- Read all dumps and copy the hardware.
3- Build clone hardware with those dumps.
4- That firmware become blacklisted and user must use those dumps with the correspondent software.
5- China buy new version of the original tool and the cycle starts again.

;) ok, I agree, I heard this story.. but I don't beleive that is still cheaper than other way.. (like stole somewhere else)

To stole a dump or source code you need:

1 - to hack into Ross Tech computers;

OR

2 - to have a mole inside Ross Tech;

OR

3 - to crack the content of the uC;

My opinion goes for the 3rd solution but that just my humble opinion.

Hello,
How do you connect Upa?
Please wiring.
Thanks!!

[andyzred]

you can read the upa manual how to connect, but even connected you will not be able to read it if the fusebits were configured in such way which will not allow future programming
