checksum question

[upyas]

i tried both numbers and it fails every time, the checksum in the bin file and the checksum pcm calculated both ways fails.

[upyas]

im stuck in a loop, retry with 2889 it allows me to re write the bin again only to ask same question

i will try the other 4245 again but it will probably brick it

[upyas]

it asked to program eprom data so i clicked yes and now its bricked

2 ecus bricked this afternoon.

will change the chips in them tonight maybe, it would be nice to find a solution for this, i can't take the chip out and hard program it every time i want to clone a ecu

[upyas]

should it still work if the os is different? they are all flash ecus

4 ecus are now socketed so bricking is easy i can just remove the flash chip and re program it

[upyas]

now im bricking them for fun, sell me your bricked ecu's guys, $50 each send as many as you have

Are the bins you're writing complete dumps, with valid eeprom data in them?
Or is it something you've found online that isn't complete?

If you've clicked OK to correct sum and it's still bricked there's something wrong with the file your writing.
Post it up here so we can check.
Dont keep wasting time and ECUs trying again.

I have never bricked a single one of these ECUs. The flash tool makes it very obvious how and what to do to avoid bricking them.

Agree with pman, this flash process has been solid for years and nothing has changed. You do need to do the fix checksum as part of the write process with ose flash tool, but other than that, if your file is good it wont brick. It sounds like there is something very wrong with your setup or files.

[upyas]

the fix checksum option is on and those box's come up after the write process and it does not matter which checksum i choose, the calculated one or the one in the bin file

[upyas]

im not really bricking the ecu's anymoe because i got spare chips and i also got 4 ecu's here with sockets so i can simply just remove them and re program them in minutes
