Can someone checksum this file for me?


Attempting to open firmware file 'C:\Users\Dimos\Desktop\Audi A3 8l  AQA 06A906032AC_ 352756 -mod.bin'

Step #1: Reading ROM info ..
 Searching for EPK signature...OK
 Searching for ECUID table...OK
 EPK         : '42/1/ME7.5/5/4013.00//F21dz/Dst04g/260899/'
 Part Number : '06A906032AC '
 Engine ID   : '1.8L R4/5VT     '
 SW Version  : '0004'
 HW Number   : '0261206580'
 SW Number   : '1037352756'

Step #2: Reading ROMSYS ..
 Startup section: word[0x008000]+word[0x00FFFE]
 @008038 Add=0x006B59 CalcAdd=0x006B59  ADD OK
 Program pages: 8k page first+last in 0x0000-0xFFFF and 0x20000-0xFFFFF
 @00803c Add=0x770305 CalcAdd=0x383792 ** FIXED **
 All param page: word[0x010000]+word[0x01FFFE]
 @01b314 Add=0x00971D CalcAdd=0x00971D  ADD OK

Step #3: Reading RSA signatures ..
 Searching for RSA offset #0...missing
 Searching for RSA offset #1...missing

Step #4: Finding CRC table(s) ..
 Searching for CRC table(s)...OK
 CRC table(s) OK

Step #5: Reading Main Data Checksums ..
 Searching for main data CRC pre block...missing
 Searching for main data CRC/csum blocks...FAIL
 Searching for main data CRC offsets...missing
 Searching for main data checksum offsets...missing
Step #5: ERROR! Skipping Main Data checksums ... UNDEFINED

Step #6: Reading Main Program Checksums ..
 Searching for main program checksum..FAIL
Step #6: ERROR! Skipping Main Program Checksums.. UNDEFINED

Step #7: Reading Multipoint Checksum Blocks ..
 Searching for multipoint block descriptor #1...missing
 Searching for multipoint block descriptor #2...FAIL
Step #7: ERROR! Skipping Multipoint Checksum Block... UNDEFINED

*** Found 3 checksums in C:\Users\Dimos\Desktop\Audi A3 8l  AQA 06A906032AC_ 352756 -mod.bin

Can you post the ORI?

It doesn't look like ME7Sum supports this file.

I will fix it if possible.

someone doubled your flash file so he can use an 29f800 chip because he was most likely out of 29f400.Split your file and correct cksum and then double it again or use 29f400 chip for this ecu.Can be done with a hexeditor in seconds.

Btw first post should be an introductory one ...
