Help [TINNO U304AA] Auth File Needed

[Deleted User]

I picked up an AT&T Radiant Core for cheap to mess with. It appears to be an MTK6739 device. Trying to pull a recovery image using SPFT but it's giving me an error that I need a proper Auth file. Tried using a couple I found online but none of them worked.

Can anyone supply me with some auth files to try? Perhaps another program instead that will work better than SPFT?

Thanks

EDIT: The official model name and number is a Tinno Mobile U304AA, rebranded to be an ATT device
