Info 2 [Q] Imerj blugroov update?

so i have managed to come across a couple of Imerj Blugroov phones its a concept dual screen dual core android phone running 2.3.4

looking for any information on changing the Rom to something newer. i have heard they were using the nexus firmware for testing.

model number comes up as : New Era DV21 (US)

i have only been able to find a Chinese site that mentions this phone but no other information anywhere.
