VVDI PROG

**automotrizVIP** · 16th January, 2018, 06:24 PM

reporting; read eeprom AT25C320 does not respond, USE ST, ATMEL.
I passed it on different adapters and soldered it on tracks, without answers from the program, reading st95320 is good, but at25c320 is not possible...........................
finish work with upa,

But for the future it would be good if this was corrected, reading unknown version shouldn't corrupt kessy.

friend, if the 93c86 data keep same before and after, it means the dump should be correct.
about your problem mostly caused reason should be on hardware, pls check again.

atmel eeprom 93c76 read bad data

mate, pls send me the log file or read error screenshot.
pls just connect device to PC with USB cable(not run software), then measure the eeprom socket PINS voltage, let me know the result.

About ST95320 beside EEPROM, there is a 'Lock byte'in STATUS. when you want to rewrite data, this Lcok byte must keep '00'.

finish work with upa,

try to this option with 4.8V, this old chip the working voltage a little higher.

So VVDI PROG to decrypt data needs only eeprom or it reads also part of MCU from this board ??

Dump was correct. It was spare key job, EE read onboard then soldered your wires. Impossible to damage. I think NEC got corrupted.

I got mine vvdi prog,
work good but need external power,
I use too original xprog-m and no need external power - that is main difference

So if someone have trouble with working VVDI Prog first please check external power to programmer

in what case you need use external power for VVDI Prog ??

Most of the chips i read without external power but some MCU's require external power!

Why this things aren't automatic? I mean, if this eeprom needs this voltage, when you choose whatever chip, voltage and other settings should set automatic.

CAS 3+ wont read mcu id c410 ok 0L15Y but cant crack mcu mesage check connecion
35080 cant erase with adapter
job done with 50$ R270

I just did one of these today with no problems, did you double check all your connections were ok?
I've had this message in the past, and turned out one of the wires wasn't making a very good connection. Re-soldered it and was fine.

When you click the "Read ID" button in the top right corner, does it actually come back with C410? The time i had a bad connection every time i clicked the 'Read ID' button it would come back a different random ID
