I was playing with a K8.9 LTE version. I successfully rooted it, tried "Official Aospa-Legacy Kindle Fire HD 8.9 (JEMLTE)" and decided to revert back to stock. I installed this version: http://forum.xda-developers.com/show....php?t=2142241 but LTE doesn't work anymore. It displays "No SIM" with the sim card that was working before. With the original AT&T card the error is not shown.
Is there a stock ROM specifically created for LTE devices? What does this warning mean: "NOTE FOR LTE USERS: This does *NOT* contain the wankit update for LTE modem firmware." ? Could it be related to my problem?
