I think it's the 2013 version as it doesn't have a camera.
I've tried the KFHD_SRTv1.3.5 and Kindle Fire Utility. It goes through all the actions installing the file etc but when rebooted it's now goes to red screen then FastBoot, even without a cable plugged in.
I've tried the info in this thread - http://forum.xda-developers.com/show....php?t=2466243
I enterd "fastboot -i 0x1949 getvar product" and got SOHO-PVT-PROD-07
fastboot -i 0x1949 reboot and it reboots straight into fastboot.
I've tried going through the actions again but nothing seems to work. Is it bricked or is there hope?
