I can't find the USA setting and yes it has been refarmed. For now it only has WCDMA preferred, WCDMA only, GSM only, then evdo, a couple PRL and their combination.

I didn't switch to that ROM. Still on the official nightly. Will give it a try. Thanks!

My pal that works at T-Mo is using their LTE test network right now, and he told me it's only in a small geographic area of town right now and requires provisioning on the back end to work. He gave me the APN configurations to try it but it doesn't work for me. So I am betting that it's not entirely switched on anywhere while they test it. Obviously HSPA+42 works great.

Post the settings so we can all try

[Q] how to enable hspa+ on nexus 4

im running on hspa and cant seem to enable hspa+, if it helps im running on the canadian wind network
You don't have to enable it... It is already enabled. If you have HSPA+ signal the phone will use it.

Android doesn't report hspa+ on the signal bars, but if you look in the about phone settings it will say hspa+.

When configuring LTE on any ROM phone force closes after ay call... Anyone else?

I've followed a few tutorials on enabling LTE on my N4 with the .33 radio. On numerous ROMs, phone FCs after any call. Cannot seem to pinpoint where the issue is coming from.

Are you using LTE only?
No. I've tried LTE/GSM and LTE/GSM/CDMA auto.

LTE on 4.2.2

Hi guys, T-Mobile just got LTE in my area, but I realize that the LTE option went away with the update. Can anyone help me out on how to get it back if it's possible, it will be a huge help. Thanks!

Hi,
have you tried this ROM and settings?
http://forum.xda-developers.com/showthread.php?t=2267890
There's a whole thread dedicated to this:
http://forum.xda-developers.com/showthread.php?t=2211618
Bottom line, you need to downgrade your radio. Additionally, it'd work best with a 4.2.1 ROM, but if you want to run a 4.2.2, you'll need to make some edits to the ROM to be fully compatible with an earlier radio. That thread has a flashable zip to edit whatever 4.2.2 ROM you have install, to make it work with the earlier radios.

Try flashing an older radio like .33 or .27 from here http://forum.xda-developers.com/showthread.php?t=2087227. May cause some issues with 4.2.2 though, backup first and try it.
Thanks for the help guys. Is it possible to downgrade back to 4.2.1 then? Because to save me some time I rather just downgrade and start from there. I saw no difference in the update.

theres no need to downgrade. flash either the .33 or .27 radio, flash this to fix in call audio https://www.box.com/s/h16b3wlrq8op6us7ifsv then change the phone settings to lte/gsm. you can change the phone settings entering *#*#4636#*#* into your dialer or via the 4636v2 app. thats all.

na, ive used every radio on 4.2.2, hspa+ only and LTE. no problems. the only real issue for tmobile users is using a an older radio on 4.2.2 without doing the in-call sound fix. thats the flashable zip that i linked you(or you can do the edit manually).
Yeah I've never had any problems with the older radios, except the no call audio issue, but that's easily fixed. There's even a script you can use so LTE settings stick on reboot.

Go into phone information then towards the bottom switch to LTE/GSM where it says "set preferred network type"

[Q] Mobile Network State Disconnected

I'm sure this has been asked before but I am finding nothing about it in my search so I'm asking for help here. I will attach a few screens to show my dilemma. I'm stuck on mobile network state disconnected. I am pretty sure my APN settings are correct. I am rooted and running Slim Bean build 8 as well.

Go to your APN and hit restore to default. Reboot and let it sit for a few minutes. Report back.

im on a gt9500 and tried this, but did not fix it for me. I have the issue while on GSM, WCDMA works fine.
Your phone doesn't come with default apns it is international. It reads the SIM and puts the generic APN settings in. You likely need to manually Input them

I had this problem on my Canadian Telus 9505 S4.. I tried the things in this Thread, and it didn't seem to work. What I ended up doing was downloading an application called "Tweakker" and it automatically detects your APN settings for you to enter manually, I did that, and then rebooted and it seemed to work for me. Hope I Helped somehow.

AT&T LTE issues.

Is anyone else finding that their phone will not connect to LTE?
I did *#*#4636#*#* and tried to change it from WCDMA Preferred, but it does not allow me to do so.
