RE: HP Prime G2 firmware.....
Hello

[About bricking a Prime]
"Are you sure that that's all [the ways to de-brick them]? No JTAG type re-flashing?"

Actually, JTAG does not give you access to the flash. It gives you access to the CPU (JTAG is present on Prime of course).
Once you have CPU access, you can then use that to download and execute a program that can access the flash.
But this means complete opening and soldering which is one level more dificult than the other methods.

As Tim said. Exam mode is the critical point here. If someone starts doing somehting to disable/modify/simulate exam mode and publish an "how to", then we will be forced completely lock down things, which would be very sad...
