EFI Hard Drive has been blocked by the current security policy

[Guest QLF]

Well this is a new one to me....

 

All i can do is switch the device on and off - after each reboot it goes to a black screen with a blue box saying "EFI Hard Drive has been blocked by the current security policy".

 

"OK" is highlighted, but the screen is dead, so unable to press it.

 

Anyone got any good ideas on how to recover? Or have i finally bricked a hudl2?

 

**Edit** - Using a keyboard with Micro USB i can press enter to get to the boot menu, but only the EFI Harddrive displays, so can only select that. I suspect that a powered USB Hub might allow me to try and boot from a USB stick with recovery on it, but no recovery files.

 

Anyone got a good suggestion?

UEFI secure boot is preventing the system from booting. Have you made any changes to the eMMC - flashing images or changing the ESP partition content etc?

 

 

The hudl will try to boot from an external micro SD so if you have a micro SD in there remove it and try again. 

 

You can try to boot from an external USB device (using an OTG cable) but it'll only boot images signed by Tesco. I tried to get the standard image to boot from a USB key but that didn't work for some reason. 

 

If you turn it off (hold power and volume up), and plug in the charger does the charging animation show?

 

Try plugging the charger in while holding volume up too.

SO it looks like after the battery died, it won't take a charge - finally found a hudl that couldn't be recovered :(

 

C'est la vie. Was great while it lasted!

I've had success recharging an ipod battery that got completely flattened after installing ipodlinux by connecting a generic 3.7v lipo charging circuit with blutack:

I reckon you could do something similar to recover your dead hudl
