Htc One M8 complete signal loss

[Josue Girald]

Please help! I bought a Tmobile Htc m8 and I am using it with a Simple Mobile sim. Everything worked fine for a whole week. Two days ago I was driving and went into a large "dead zone" where reception is zero. After I got out of it signal never came back. I tried everything: changed my sim,factory reset,restart,changing apn's,network selection(both manual and auto)! I can not get my signal back. Also,when I run the Network Finding option,I got PR Claro(Verizon),Metro pcs,Simple Mobile and At&t,but no Tmobile. Please help me fix my Htc!
