I couldnt get my 4g back I had factory reset my ohine at least 3 times and once the 4g came back for like almost an hr and then it dissappears:mad: I JUST WANT MY 4g back(stupid update) so when i was going through my phone I noted my LTE status was unknown and my phone was cdma evdo I guess thats the crappy 3g so Im getting extremly desperate I took out the sim card and did a battery pull and everything no dice I finally note these holes under the battery cover(finally the topic of this thread sorry lol:eek:) I see L1 L2 and R which im guessing means reset or something Im just curious do you think this will fix my phone If i tamper with these things or what thanks for listening. oh yeah I even tred the **583385## code and that was no dice either even when i did an api check it said data type = Null
 
Your LTE modem driver is not loading.
If LTE version under status says unknown, you will not get 4g, no matter what you do.
Your options: update the modem drivers (there's a thread with eg06 I started earlier),
Do a full Odin upgrade to 2.2.2 with my tar.md5 or at least a thorough 2.2.1 using option 2 from the Odin thread, or finally return the phone to MetroPCS for an exchange.
Little holes under the battery compartment won't help you there!
