Pcr2.1 eep - How i can know if the eeprom is locked or unlocked ?

[CHIPTUNINGDZ]

Hello everyone
how i can know if the eeprome file was unlocked before ?
i'm trying a lot of tests and comparing, without results

for exemple :
to unlock it ( 0024A-00252 )

DE161A9443B211E2 XOR FFFFFFFFFFFFFFFF = 21E9E56BBC4DEE1D
so
21E9E56BBC4DEE1D XOR FFFFFFFFFFFFFFFF = DE161A9443B211E2

how i can detect if the eeprom file binary is unlocked before ?

kess by obd
i know
but i want to do that with winols
how kess do that ? how it can determine if the eeprom is locked or not

[voltechcar]

I dont know, I use new protocool by obd, not need unlock ecu.

[teerak2uk]

Id it by obd

[morgano]

There is a measurement block in diagnose who answers if the ecu is unlocked or not. Kess read from there. Is not possible just by eeprom dump determine if the eeprom is locked or already unlocked.

In vcds in advanced measuring blocks you can search for "sample"

X_ECU_TYPE-LVSWMD_ISSAMPLEMODE ---> PRODUCTION = locked
X_ECU_TYPE-LVSWMD_ISSAMPLEMODE ---> SAMPLE = unlocked

or check measuring block 497 or 359...

i guess that is what kess also do automaticly when id-ed to tell you if it is locked or unlocked, it does not read eeprom content over obd if thought that

Exactly!!!!!

[ohkarol]

write modified file, if not starts then its locked ;)

[sdtsedat]

write modified file, if not starts then its locked ;)

And how to recover ecu ?

[ohkarol]

flash original file back

[sdtsedat]

flash original file back

It doesn't reflash it.. I have done this and need flash SGO.. Ecu was bricked

[michaga]

And how to recover ecu ?

I think you can write ori file whether the ecu is locked or not. But I am not pretty sure because I did not have to try it :)

this is a good joke...

make id with fgtech...will tell you on the screen if ecu is locked or unlocked

thanks for this informations
so
there are some blocks or data in the dump file (algo) to compare it with the 8 bytes of the eeprom
because i want to do that manually

[SportKnight]

kess and mpps do it in ecuid

[krzysdro1974]

Find the PCR Unlocker program on the network.
Use it to unlock the file and compare both files.

Wtf!

Have you read entrire thread or just jumped in to say first thing that pass over your mind?

How can this help you decide which of the two eeprom dumps is the locked one and ehich one the unlocked if you don't know state before applying the unlocker???

[grga59]

It's pretty simple, read the eeprom, do the program and then compare both eeproms and if nothing changed then it was already unlocked

You'd better change the job if this is your full knowledge of this particular matter.

No need to be agressive my man, i was just giving you one of the solutions, of course you have all the knowledge of this world and this kind of work, be nice and respectful please

Not aggressive at all, i used very kind words with you. What i said was a friendly advice. Go and test the procedure you suggested before giving advice to anyone else, you will notice you are cheating people with it.

Nice day

[grga59]

I did that's why i gave this solution my man, there is no cheating if you use a bit of brain, happy new year
