Hello guys, i have an GQ-4x4 1.0 , Soft 7.11

I can read an M29f400FB with ADP-019 v4.1, but cant erase or re write.

checked pins , usb cable checked.

Check ID say :
Device id (hex) C0EC
Manufacture not in library
type unknown device
revision -

But anyway let me read it

Any idea? :/

True if you're dealing with a masked version.

I verify soft, contact pins and dump, it was ok

I buyed another ST 29f400 "BB" and i can read , erase and write.

Maybe old eeprom was failed

Thank you very much for your interest for helping

Kind regards

When you say verify is ok, you verify against what file?

Your datasheet gives the same ID as a Micron. Could the ST be a mask?
danmarq Posted - 05/18/2017 : 06:33:09

This is from an ECU EMS3134 what i need immo off

Is an ST chip , but only i can find this datasheet about it xxxxxxFB

ID is no correct. The read is good or garbage?
