edc17 help me pleaseee

[kospoz]

hi to everyone right now i want to cry i am very sad!
I have one edc17c46 ecu from octavia 5 2.0 cr and i read it with galletto in boot mode.
Everything ok then i make some changes to the flash with the winols i dont let it to make checksum and i tried to write back to the ecu.I let galletto to make checksum because is not the first time to read write same type ecu.Finally when was done i put it on car and started ok.Then i i took it off to close the bottom from ecu and return it to car after 30 minutes.Then i tried to start the car and nothing!!!!The cooler fan turning like crazy.I realized that the checksum was the problem but i do not know why.I flash it again the same result.In the end i flashed it with the first flash which had the car and the same thing!Anyone please help me

so you have written back original file including original EEPROM?

[Babos]

Do foto from ecu and share here!! do good foto pin who soldering!!
If you write back original full car still not start?
Fan work if ecu sleep or he still in boot!!

[arvedo]

surely ecu tin residues, and can burn any part of it.
always look good before mounting ecu.
I hope you can fix it

glue had to do a short circuit, a ECU for the exchange

If car started and ran fine...then forget about checksum issues. of course wirting ori back did not help.
ecu is not stuck in boot mode.
can u connect via OBD and diag?
usually fan running means no coms with flash.
check PCB for damage and check fuses

no only the flash.When i changed the first data with winols the program show me one board with six suggestions. 1-->change value with take out memory protection 2-->change value for entire operation 3-->change value 4-->cancel...........
I tick the first with take out memory protection

the second time the car dont started.I have not communication with the ecu i use vcds

If you have original EEPROM write that back. If this doesn't work it looks like the ECU is stuck in boot mode.
