First time posting here, so I hope someone can help me. I had Transformer Infinity since last year, but had to send it in for repairs last month (January 2013). The mainboard on the tablet was replaced as the device would not power up.
When I got the tablet back, I ran all the updates, including the firmware update through the "Settings" --> "About Tablet" --> "System Firmware Update", but the device would report back as "There is no update available for your device currently". I didn't think much about updating the firmware, until I tried to use my microSD cards. Although my 2GB and 4 GB (Kingston - not sure of the class speed) would post, both cards would report back as 0 bytes available. My 32 GB Sandisk (Class 10) would not even mount. It didn't matter what format the microSD card was in (NTFS, FAT, FAT32, exFAT), as they all showed 0 bytes on the 2 and 4 GB microSD.
Anyhow, I was looking on the internet, and the recommendation was to update the firmware on the tablet. The firmware build number is US_epad-10.4.4.16-20120927. The current version I found on Asus website is 10.4.4.25. The tablet is running Android OS 4.1.1 (Jelly Bean).
So here's my problem, how do I update the firmware if the Asus automatic firmware update does not work, and the microSD card slot does not work (because it needs the firmware update)?
All the documentation I see online shows how to do it with the microSD card, but since I don't have a working microSD card reader, I can't use that option.
I've also tried Asus technical support live chat, and they gave me the run around answer... that the tablet will automatically update the firmware as long as the device is logged on to my gmail account (which it is).
Any help would be appreciated, otherwise my last option is to root the device.
