As you know no one can install Gun Bros even on their old devices because the Glu server does not download the data anymore. You can download Gun Bros 1 on the google play store still but it wont download the rest of the game to the SD card. If anyone still has gun bros running on their old devices can you please post your SD data online? This data is found in sdcard\Android\data\com.glu.android.gunbros_free
The data differs for different devices, Adreno, Tegra, Mali etc. I am particularly looking for the Tegra data! It would be greatly appreciated. Thanks.
