Sounds exactly like what I am looking for. I flashed a modified firmware about 6 weeks ago. About 4 weeks ago I suddenly couldn't make or receive calls when using LTE. My 3g is gone so I have to be on 2g to make or receive calls. Then about 2 weeks ago (after a simple reboot) I started getting "error99: unable to connect" for WiFi calling.
If you do get a version up without the red warning text I would appreciate it. If not, April 10th and the M9 are approaching quickly. I don't know why something so minor bugs me that much but it would be appreciated nonetheless. In the meantime I will flash the one you have up. Thanks again.
