thanks for your reply.
I've tried every rom flash I could including 710B and the result was the same, only 306MB of RAM, but I have always returned to uberoid because it is the best result obtained using AnTuTu, 2470 total is more or less what I did with the old rom, so I'm starting to believe that the old rom was manipulated to show false 1GB RAM
Do you think that would improve the operation uberoid 1.2?
This is my appliance inside
In Russian pages call it mk802 + + with a heatsink and external wifi
I'm hoping that I get the same model from the same vendor, you'd know how I can get the rom of the new device when I arrive?
