Hi to all, at the moment i'm trying to repair the Blue&Me modules in Fiat/Alfa/Lancia. These modules die easily after change/discharge of the battery. I wanted to share what i know about their fix and hope someone know more than me can share his info. The problem is the Firmware that gets corrupted, we can found the firmware in a NAND Flash (BGA63) that is over the Micro (STA2062, a protected Micro which i've not been able to find any info about R/W it). There are a 4 types of NAND flash that we can find in these modules, 2 types are Micron (NW140 and NQ278) and 2 types are Samsung, i read and write them with TL866II (for now, without success for the repair). At our workshop now we send the bricked B&Me to someone that can fix them and after his repair i open them and i found every time the same 'repair signs' (a glue/paste around the NAND and some solder joints on the board on some test point that seems a J-tag connection). During the repair he can also change the compatibility of the module changing his Firmware (Lancia Delta can became Fiat 500/Grande Punto ecc..). I've got only one hint from him and nothing else, he does something with Martech programmer. There are the informations i've got at the moment, i hope someone knows more than me and we can share our infos!
