Carprog 8.21 OBD read/write not working

[wesleyheida]

Hello,

I am trying to read my micronas cdc32 flash + 24c32 by obd Carprog A1 cable to get pin, cs, mac, keys etc
I have read 24C32 manually by A6 cable clip and saved for backup. (verify ok)
Then I FF 0x812 - 0x9BF to delete immo data and get in service mode.
Then written the service mode bin back to the 24C32 chip. (verify ok)
Then Read the 24C32 chip by a6 clip to confirm immo data is FF out (all ok)

Put cluster back together. Connected via obd A1 cable bench setup.
Launched carprog golf5 2007 -> 0.5
Carprog see partnumber, coding, type and SW so can communication works. It also reads fault codes.
Opened original eeprom dump 24C32 to write via OBD
When trying to write it stays at ''entering write mode... attempt 1'' then it asks to turn ignition off for 5 sec etc.. so it fails to write...

Anyone knows why it fails to write original dump back to 24C32 via OBD A1 cable?

It is a carprog clone. came with 4x texas instruments hct125m chips (manually read/write 24c32 works, so looks like good clone)
A1 cable looks good as original. all resistors and capacitors in the right place.
Everything is performed with 12V to carprog.

I have attached pictures from carprog front/back and A1 cable + 24c32 dump original and service mode

Method I am trying:https://codecard.eu/index.php?act=vi...Id=433&ccUser=

FIXED! Software issue. Installed carprog 5.31 and works like a charm!
