Hello, in that case please go to this link: , go to Section V - there are 7 ROM cooks for the HTL22 and I have tested 5 of them. They are all working but so far the one that has given me the most stability and battery life is number 7- Rom Soku4.3 Android 4.3 Sense 5.5.
Please be advice that Flashing these ROMs may brick your phone if not done properly. Do it on your responsibility.
