Another story: Object: Citroen C5 2002 2.2l 4HX. EDC15C2 single connector. Tool: Galletto 1260. Tryed to reflash ECU with modified firmware. Readed original, everything OK. When tryed to write got an error and ECU dead. Battery as in perfect condition and it can't be an cause. Maybe because of cable extander. Maybe... Tryed to reanimate in boot mode - no luck, no way. Last chance - removing of EPROM and programing i external programmer. As a programmer was used EZOflash, especialy designed for programing of EPROM, PROM, FLASH and other memory chips. Can be done by any electronic amateur. After reading the content of flash chip I foud it fuly erased, all FFFF. Writed original soft, soldered chip back into ECU and voala... ECU works.
