- SXX 7y agoUnless your car has DRM that prevents you from tampering with it's flash memory...
- Avamander 7y agoIt takes more than that to replace a BGA flash chip.
- cptskippy 7y agoNot that much. BGA chips aren't that hard with a hot air station. I've done plenty of de-soldering and reflow using just a hot air gun.

- lightedman 7y agoA BGA can be replaced with a freaking heat gun from Home Depot and some solder braid and some flux. Source: I used to repair cable boxes for CTDI. While everyone else is using their Metcal station and wasting 5 minutes, I've got the BGA off, board deballed, and a new BGA package installed and ready for PKI in less than 45 seconds with a heat gun.

- spinach 7y agoSeems a bit more complicated than just unsoldering the old chip and putting in a new one. https://web.archive.org/web/20190621052637/http://teslaservicemanual.com/2019/01/18/replacing-emmc-in-mcu.html https://web.archive.org/web/20190621052637/http://teslaservi...
- joezydeco 7y agoHowever, if it's similar to how Apple does it, the chip might be bound to the processor via a serial number or some other magic that's burned into the NAND at manufacturing, or OTP on the processor, or something else. It's not just a matter of "oh just go get a Hynix NAND part from DigiKey and reball the PCB". At minimum you need to copy the data over. At worst you need to bless the part with whatever secret sauce Tesla is using at the factory.
