Sorry if this was discussed earlier but:
1. what year & model is your Tesla
2. where & how did you get your eMMC chip upgraded to 32GB for $800
I'd love to have my 2015 P85D's browser responsive again... hopefully without having to refequently do a double scroll wheel hold down RESET
@TonyT did the repair in Southern California, including taking the MCU apart and putting it back together. If you mail it in and can do the disassembly and assembly it is cheaper. I have a late 2014 85 (AP1) with 85k miles.
