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!

Any more news to share regarding this repair? i have 51926903 to repair...
Nothing mate, when i have time i try to do some tests but i don't have so much time. Anyway recently i've tried reballing an original Nand Flash from Blue&Me, it's not so easy, i don't have adapter so i have reballed every single ball one to one with the help of a tweezers.
In the next days i will reprogram it if i find a good dump (this is the real problem!) and then solder it again.
Martech programmer does not programm nand and cpu from Blue&me
Interested in this ,any further development ?
Nothing, i don't have a good dump for trying. Anyway i don't know if it's worth, now i pay €70 for repair a faulty unit, but it's also strange that i pay only €70 for a reballing + reprogramming of Nand Flash..
yes can fix without soldering but price is 2500 euro, and you can find here https://blueflasher.it/home?hl=en.. 70 euro for repair is cheap, in UK people charge minimum 150 pounds for repair
