Hello!

Bricked Defender ecu with Nanocom, when flashing.
Tried desolder chip and write full bin file from Discovery with autobox, but still not working, cant connect with Nanocom
Some sugestions how to debrick ecu?
Maybe with BDM?

why don`t you ask the nanocom guys for support ? did you back up the flash ?

**Defender66** · 30th March, 2020, 03:07 PM

Because nanocom is useless when ecu is not answering via obd

OK. If you have written in the right flash and soldered it back in correctly it will boot. So please check your soldering.
I wish you had posted this before you removed the flash as I can recover these on the bench via a bootmode JTAG reflash. Done this many times.

now I order another wone, script I already have.

OK you sound like you have this covered. Post up your kess file and I can tell you if it's ok or not. If it's not ok, I can repair it as well for you.
