I’ve got a second EzBook 3 Pro, it appears to be a V5 one.
And on the russian’s 4PDA forum found the following working unlocked “BIOSses”

BIOS V5 Date 11/06/2017 14:30:19 Ver 3BANS010 JUMPER10x.P8.WP313P.NhNAUHL02
V5

BIOS V6 Date 12/05/2017 19:25:21 Ver 3BANS010 Jumper10x.P8.WP3132.NHNAUHL01
V6

Original message here (note: on Russian)

IMPORTANT!
Please be careful and check twice about the version you have: these ones are not compatible between, so it is possible to brick you 3Pro with incorrect bios version. Well, as usual – if you want to do it –  it’s you own risk. I’m not responsible if you damage your Laptop!

Yep, sure
Thanks!

Anyway, I’m not so afraid of not restoring it, as have got some valuable knowledge about UEFI and will have one more 3 pro in about < month (or will be 2, if this will be restored 🙂 )

Well,

It is not possible to flash from v6 to v4. I’ve bricked my 3 pro 🙁

Anyway it was a good exp.

So, if no success with restoring on programmer – my daughter will have a nice-looking toy (after batteries removal) :)))
