I bought a GV-21 android stick, which is the same as the .
Anyway, to cut a long story short, when it arrived it already had the newest firmware on it. But that firmware is bad. XBMCAndroid doesn't work on it, Wi-Fi is poor and some apps just show a black screen. I had one before Christmas with the old Firmware and it was brilliant.
I have emailed for the old firmware but i get directed to the same link, which seems to be corrupt.

Is it possible i can replace the bootfs file inside the folder of this firmware -
With the bootfs file that is found in the folder of this firmware? -

It is for the same stick, but the bootfs file is corrupt in the link of the firmware i need, and it's the only place i can find it. (I've looked everywhere).

I will be over the moon if anyone can help me.
