I recently bought an unlocked N910S but I seem to be having some problems with LTE (I live in the US) and can't seem to access the network mode menu in 'more networks' (the option is grayed out).
Some things I've tried:
Added the access point for my provider (Cricket/AT&T)
Booting in safe mode (no changes).
Flashing other regions' stock roms (N910T, N910V, N910T); Odin gets stuck at NAND wrtie start and only N910S stock rom seems to work.
Accessing Network Mode settings through the hidden menu (can get LTE if LTE17 or LTE All is selected but can't make or receive any calls).
Any help would be appreciated.
Thank you.

Using ATT LTE now. Stock rooted to remove a bunch of Korean apps. Use band 5 preferred in the hidden Menu. Band 17 also LTE but couldn't make phone calls. ATT LTE band 2, 4, 5, 17

Hello,
I've just rooted my Legend for the first time. To do this, I downgraded to 1.31 via RUU, then rooted using the Modaco guide.
After the RUU downgrade, I noticed that the phone said "Emergency Calls Only". Being a complete noob, I continued along with the rooting process figuring that the root flash and later mod flash might fix the problem.
After the root, I still had emergency service only. Being excited that the root worked, I went ahead and installer Rom Manager, rebooted into Clockworkmod Recovery and installed Cyanogen 6.1.
Still "emergency calls only".
I looked in Network Operators to see if my provider (Bell Canada) was visible. Sure enough, it was there. I tried to join the mobile network but the device just sits there spinning until it times out. I set the correct APN settings, but of course that didn't help - I basic GSM service doesn't work, let alone 3G.
I then found an app called Secret Settings, which gives access to a bunch of nifty hidden configuration options. I worked my way through each of the preferred network types. None of them worked.
I assume that this has something to do with the radio firmware flashed during the downgrade, although it looked like radio was also flashed during root.
So here I sit with a fancy WiFi-only device that used to be a phone. Can this be fixed? What are my options?
Please help a very technical but new-to-android-modding noob out. Thanks in advance!
Well, I seem to have fixed my own problem. Awesome!
Bell Canada HTC Legend users - if you've downgraded, rooted and are finding you have no service, or emergency only service...
Download "Secret Setting" from the market.
Tap Phone Information
Scroll down to "Set preferred network type"
Select "GSM/CDMA auto (PRL)"
Exit to the home screen
In your phone's Settings menu, select Wireless and Networks
Select Mobile Networks -> Network Operators
Make sure you're connected to Bell
Reboot
Dial *#*#4636#*#* on your Phone, it does the same thing as "Secret Settings" and doesn't require you to install anything.
It's been listed a number of times on the forums. You also don't need to reboot to change to GSM/CDMA auto PRL, although you probably want to select WCDMA only.
Hi All,
I know its a topic which has been addressed differently in different threads. I am a user from India and have a GSM SIM. I have got a Verizon S4 phone. I tried using it with Vodafone SIM and get a problem in using it. Surprisingly a NOTE 2 from Verizon works just fine. I am able to use it for data with 3G but not able to use it for voice. Following steps have been tried already.
- Default Options of using Global Mode and GSM/UMTS ** Doesnt search the network at all.
- Hidden Menu Changes using # codes. ** Shows network but emergency mode only.
- Phone Info app to change the mode. ** Shows network but emergency mode only.
- RF Band change using the hidden menu. ** Shows network but emergency mode only.
It does say that it has GSM radio but cant be used for some software reason I suppose. I checked with Verizon Rep and was told that it cannot be used in India with a GSM SIM and would need the Verizon SIM only to connect with International Roaming.
I was able to install Wanam Lite I-9505 ROM on the phone and patch it with Loki-Doki patch and the phone was booting. But the network signal was not getting picked up. I had data connectivity but no voice or SMS. Is it possible to patch the I-9505 radio over to I-545 and / or force it use GSM as the primary modem.
Any idea for this?

Have you messed with your APN settings? I use a I545 with T-mobile here in the states and all I had to do was change the APN settings
I have bought second hand G2 and it had already KK installed. Baseband M8974A, kernel 3.4.0
build number KOT49I.D80220a, software version D80220a-HKG-XX. I have rooted it only and everything works fine except I don't have LTE option in network mode. Is there anything I can do enable it? Also, when I use 2G only the signal comes and goes sometimes (I have pretty strong 2G signal so that shouldn't be happening). Please help

I have done this:
If anyone of you has root, but LTE/4G is not sticking after root, you can try the following:
-In build.prop change ro.telephony.default_network=9 from 9 to 11!
-Now you got LTE settings in "settings / tethering & networks / mobile networks / network mode" menu.
-Choose the option you want and includes LTE and it sticks after a reboot!
Now I have LTE in option. But somehow managed to silent some system sounds... For example keyboard clicks... Dunno how
I have a i9505 running 4.2.2 (UFNB8, DBT CSC) stock, non-rooted. My problem is that I still can't get LTE/WCDMA to display as an available option in Network Mode. Operator is Telenet (MVNO, Belgium). I am in a 4G area, according to the operator my SIM card is 4G capable and my IMEI has been 4G activated. According to them I should be able to connect to the LTE netwrok, but no go. They advised factory reset but I don't want to do that for now as I am not sure it will help. I remember seeing LTE as available when I roam (in roaming my MNC is different though).
Any ideas (apart from rooting and forcing LTE radio on?).
How does the 9505 decide when to turn on the LTE radio? Is it based on getting an LTE signal or is something defined on configuration file level per MCC/MNC...?
Cheers.
OK, I should have searched more. But for future generations' sake, apparently there are two possible reasons:
1. Need a factory reset (still don't understand why?!)
2. Your phone's CSC is not supported on your current carrier's network (apparently this is checked and there's a whitelist of some sort)
In my case it was 1 - I reset and now LTE/WCDMA appears.
Cheers
So my lte/cdma mode doesnt seem to work at all, i know i have 4g but when i turn on my phone it says mobile network (under settings) connecting and then the mobile network type keeps flashing from lte to unknown, however if i i switch to cdma mode 3g works fine so does anyone know a fix to lte ? i already reflashed with odin and also restored and did all that (sm-g900r4) i also attempted to do a nanroid restore but that didnt fix it either :/
