How to write safety PCR 2.1 with Galletto v54 China clone!


1. Read flash OBD with fgtech v54 clone;



2 Open ecu Carefully!! and put it back to car to test if you don't destroy it when you open;




3 read eeprom 25640 with 2 different programmers(i used upa and xprog M), and compare it;




4 unlock with program PCR2.1-Simos8 Unlock 1.1 25640 eeprom (Search it on MHHAUTO forum);




5 solder eeprom back;




6 start car;




7 go with VCDS look variable Measuring block 497;

If production it's locked;

If sample then unlocked ;




8 read flash again by obd(it will be the same like first read);




9 modify files and make checksum with winOLS;




10 write flash by OBD, if fail, write original without read id data;




Here is a manual way how to do the unlock in Winols:




open the eeprom (25640) on winols

choose the decimal mode

and 16 bit

go to the address 24A

24A 24C 24E and 250

we will calculate this 4 value

you will 65535 - 24A value

write it to 24A

for example on my file 17052 is 24A value

65535 - 17052

48483

you will write 48483 to 24A

the you will do it same for 24C

65535 - 24C = will new value

for example in my file 34224 is 24C value

65535 - 34224 = 31311 is new value for 24C

you will calcuate this 4 value

and save and write the file

after do that

to be sure



calculate the all 4 values ori and tuned
