This dump is from a correct ECU. With this file car work perfectly. I want to clone the ECU but I can't write file on ECU that I want to clone. I have tl866a programmer

I have tried but no success. I have galleto v54 and I try in boot mode and via OBD but nothing, this ECU not communicate with programmer, so I accept to remove the flash (29f400bt) to re-write with tl866 but I can't write, this flash is new I buy the new because I mind the ecu flas is damaged. I don't know why tl866 can programm this flash. I can read but no write

Yes, i have erase before and writing. I don't know why. When i try an example dump file with a small size (just exaple, not correct dump) i can be write, but when i try a correct file like file that i have post i cant mate

make sure your selecting the correct chip.... either amd AM29F400BT or st M29F400BT not what you have selected in the picture then try again

i would do

re-open soft

erase twice to be sure
blank check twice and verify

then try to write.
