Calypso 2 firmware update fails with 'Error'

Thanks.

I did a factory reset, after which the firmware upgrade was fine.

We want to help resolve your failed software update, @jxmfpggr. 

There are a number of things that may be preventing your device from updating. Below are a few: 

• AT&T Branded Device - Software update releases are only available for AT&T branded devices. This means if you brought your device from another carrier, it may not download. You may need to contact the manufacturer. 
• The device must be on the AT&T network to download the update.  
• Space - If your device does not have enough space, consider erasing unneeded files to make room.
• If the device was not originally on the AT&T network, the update may fail.
• Power - Your device may need at least 80% battery power.
