	How to dump firmware from Renesas (NEC) V850E2? « on: February 20, 2019, 12:06:19 PM »

Hi,

I hope that someone can help me to dump the firmware from a Renesas V850E2 PD70F4000. Unfortunately it is protected.

Thank you for reading!

Regards

Hi,

Afaik there are no known methods to unlock a locked such NEC V850 mcu.
Only way to retreive a dump if you can unlock it using some higher level command (if supported).
I know for NEC clusters this is possible, but I don't know to which module you are referring ...

Thank you for your answer. What are you meaning with NEC clusters?

Here is the link top the user manual. https://anon.to/7tUEoU
Alternate Link if it doesn't work. https://anon.to/a1laJS (V850E2/Fx4-H User Manual)

Can you have a look, if there is some possibility?

Thank you.

I meant clusters based on a V850 mcu which is common for VAG. What module are you working on?
