renault bosch need new code

[irfa]

hello frıends

old EPROM is damaged, new EPROM is inserted but old code does not fit, new code can be given to the file
attached files
thanks

[irfa]

I still need help

[richiebb]

not sure but....... try code 1234 with this dump.

i never change code so.......... ¯\_(ツ)_/¯..... also the dump has no calculated checksum
please report.

Edit: Remove Dump

[irfa]

ok.thanks,:)

my frıend eprom code data adress #4E0
checsum data #500 and #520

[richiebb]

Sorry for that, try this.
I still do not know how to calculate the checksum.
try and report

Edit: Remove Dump

[richiebb]

mate I believe that without the checksum it will not work.
I really want to help you................. one last attempt ......... if it does not work try with your dump code 0123

Edit: Remove Dump

[Raimax]

Checksum is not enough. Still very important 540h line. It's complicated

[irfa]

Thanks for helping my friend,but it does not work because there is no correct provisioning,again thanks

Do not give up, mate, there is still the two-digit method since it shares the algorithm of the RCD310.
let the NEC give us the correct values

try save mod file and after turn on read eeprom again.

salam
I think the first two digits of the code is 55xx

[neverseenpotato]

if this can help you in the attach there are files pair of nec and eprom95256
pre code from the label is B764

[irfa]

sorry frıends,I could not test the files because this radion screen was on the car,i will try it at the first opportunity when the car comes

Hi,

Try ... 5678
529610

hello fellow IRFA.
I could decipher how is the checksum, 100% tested, as for the counter I'm not very sure, but analyzing several dumps I think I'm very close.
I know that you must be a little bit cranky to try ... let's do it one more time

I hope it works, this topic has taken my sleep.
regards

Code is wrong. Should be BD 36 04 47. CRC is correct. The easiest in this algorithm. Counter is wrong

and what is the difference between this 01 02 03 04 and this 31 62 53 C4

NEC does not accept these 01 02 03 04 code bytes ?

if you know, why don't write correct counter bytes

I can not explain why. This has already been developed by the programmer
I can not help those members who do not respect me. These are my rules

please do not write the subject if you will not help,
no one wants help from you

[Bllinda]

I'm thinking that you really will figure out where the code is.
Need help with asams ;)
