How to revive Prime from sudden death

[René Franquinet]

Hi Dale

Thank you for the advice. The [Symb] [Pin in the hole] indeed worked as far as to reboot the Prime. The first update gave on the screen of the Prime several times the message: Error! Unknown command: e7. After a [Symb] [Pin] session I read the following message: CodeEntry:0x0. Hp Prime recovery mode V13. After updating to the newest version, which was o.k. according to a message in the Connectivity Kit, I tried to reboot/start the Prime. But I have not succeeded until now. Using your method several times I have updated the Prime already three times.
One thing is almost certain: the device is still alive.
What follow up do I have?
