Ti50 external flash/enrollment question

Support
1

For Ti50 devices, is the only option to bypass enrollment to flash UEFI?

If I were to edit the VPD with a programmer, would it just brick the device? Are there any workarounds for this if so?

2

do you mean in the context of AP RO firmware verification?

3

Yes, so if you can’t access developer mode to disable AP RO firmware verification and are flashing externally with a programmer (either full ROM or modifying VPD to deprovision)

4

I’d have to check if the AP RO firmware verification covers the VPD region. if it does, there has to be a procedure to account for serial # changes etc

5

If you flash UEFI you will still trip RO verification and the device wouldn’t boot.

6

So basically these devices will are just e-waste if you can’t get the company to deprovision?

7

I recall someone saying that the RO region is only verified on GSC reset, so you could flash without rebooting the GSC. But take that with a grain of salt.

Does powerwashing/recovery reset the security chip?
