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

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.
