I have ICS-SUPERLITE-4.2 on Rogers and i totally lost LTE. I wrote in many existing threads and dev section and no one answered.
I lost LTE, even in areas of full reception, i dont have it, i used stock APN and LTE APN and still dont get it. I do get 4G.
Other on rogers running 4.2 have lte, just less reception so im guessing radio is not the problem. Any idea?
mhx did say he broke lte in 4.1 so maybe you got something from that. im flashing now and ill see how it goies
well im on 4.2 so its supposed to be fixed
I was having lte issues on 4.2 aswell

LTE works fine. Just make sure it says ltemobile.apn instead of rogers-core. If it still doesnt work then go int the phones menu *#2263# and select option 4. After that go back into the menu again and select 1 for automatic.

I've had to use the *#2263# option to get LTE on every ICS ROM I have tried so far, works great but sometimes I have had to redo it after the 2nd and 3rd reboot for it to take...
Another solution is after you flash an ICS ROM is to have patience , if you wait 5 minutes or so after flashing, before even touching\unlocking the screen, then most of the time everything settles in nicely on its own.
if ur using rogers with the ics leaks, there's several issues. Call id and lack of lte being one of them. This issue is present with all of them, it is an unstable leal after all. i believe lack of lte unless near a strong connection is due to uclca4 issues.
well after doing what i wrote 2 posts above, i have no issues with phone except for reboot/power off hang, i also get the occasional 2-3 second lag but its quite rare. Besides, im very haapy with rom, battery life is much better than GB
no lte after ics leak
I've the same issue with AT&T in Miami which has a strong LTE network. LTE worked great with GB. After installing the ICS leak all I get is HSPA:11. When I go into *#2263# it says RAT Selection option is restricted. Anyone have a solution?

Probably don't have the correct apn. apn needs to be set to pta in order to get lte.

Ditto - well actually I AM seeing LTE, but a drastically reduced data rates. Does not seem to matter what ROM, or Kernel or how many times I have re-flashed or re-flashed just the ICS Radio, I get roughly HALF of what I was seeing on GB. Ugh. I don't WANNA go back to Gingerbread. I just want perfection. Is that too much to ask for?

It's not the APN, at least in my case. It just crappy reception, and it happened exactly when I flashed ICS, and has been like that ever since. This in spite of re-flashing the Olin leak, reflashing the the radio, etc. It really irks me, and I do NOT want to go back to GB

reflash the radio then you should be ok.
apn is set to PTA so not sure what to try next.

RAT Selection option is restricted
Just flashed SeanZ ICS 4.2A-7 ROM and i727UCAL4 modem. I'm still getting "RAT Selection option is restricted". There is nothing else on that screen. This has been 3 different radios now and I cannot get a screen that allows me to select the radio band.
Would flashing a different kernel work? Any other ideas?
I'm on the stock ICS. Is it possible to disable LTE, because I am not in an LTE area. And I would like to have everything my battery has to offer.

You don't need to change anything. Your battery will only draw more when actually using lte. For example, I get much longer battery life at home (no lte) with a lot more use then I do on days when I work and am in an lte area with little use.

I believe there is a way to turn off lte (personally I don't know how). Data is always on (unless u manually override it) and it picks up the signal. If it picks up data from lte then it shows as lte and if not then it stays at 4g. Sorry, I know I worded this poorly and it is confusing as a result. I feel lte isnt constantly searched for but rather goes through the data (which is constantly searched for). It simply notes whether the data as delivered via lte or 4g. Again, sorry for the rambling post and note that this isn't fact but merely my opinion. If anyone knows for sure, please chime in

There are two radios in the SR, one for GSM/UMTS/EDGE/HSPA and one for LTE. LTE is data only, all voice calls still go over the GSM radio.
The phone prefers LTE for data, so if you're in an area of weak or no LTE service then it searches for LTE periodically. The worst case is areas of weak LTE as the phone will hunt back and forth between GSM and LTE radios.
LTE cannot be disabled in the stock ICS rom.
CM9 has a Network Mode option to select between GSM or GSM/LTE. I switch to GSM only while at home as the LTE signal is marginal there.
You can disable lte thru the build.prop... but don't do it unless you know what you are doing... i have a set of bad ass tweaks that will do this for you and will be posting in the dev section as soon as i get all the bugs worked out

Wouldnt running a RAT unlocked radio keep it from searching for LTE? I run the UXLF3 on mohans stock/deodexed UCLF6 and dialed *#2263# and changed to WCDMA ALL. My way of thinking was even if LTE was on, the phone wasnt searching for it. Right/wrong?
In a different thread about turning off LTE radio, someone was saying that you cannot turn off the radio itself. You can still turn off the LTE mode (which I presume only tells Android not to try to use the LTE radio) if you have a RAT-unlocked radio (e.g. UXCLF3 from Seanz' Sky ICS thread).
I'm using Seanzscream's Sky ICS ROM and in the latest version (4.2F-7B) you can switch off LTE from the Mobile Networks -> Network Mode menu instead of going through the *#2263# Service menu.

Actually mine doesn't work. I saw the option for it so I flashed the uxlf3 and it still doesn't work. Whatever I select holds for a couple seconds and then defaults back to the auto setting. (GSM/HSPA/LTE auto)
That is correct. You CANNOT disable LTE Radio (you can change the preferred network mode).
- You need to be first SIM Unlocked and have a RAT Unlcoked Radio.
- And, you need a ROM with that feature enabled. My EMBRYO ROMS have always supported this (I need it too ).
Will turning off the LTE also disable the 4G? We do not have LTE here in podunk SC. I am running TC JB 4.1.1 with InstigatorX 6.3.4. Would love to keep the 4G but desperate to find a battery fix that works.
I think cm 10 allows you to toggle networks to get 3g not for certain though
I know embryo 5.1 allows network change with requirements

correct LTE data is a based off of Network Map location you can find that on your Carriers webpage in most cases
I'm running the latest stock JB Leak (K1), I've flashed the K1 and HE radios in CWM but all I ever get is a 3g signal in areas I'd usually get 4 bars of LTE.
I've already tried:
Flashing K1 and HE Radios in CWM
Restarting
Changing Network mode to CDMA/LTE from Global
Picking LTE - Verizon Internet in Access Point Names
After flashing a radio hitting Clear Cache and Dalvik Cache
Restarting without SIM in and then Restarting with the SIM
Thanks in advance.
What did you use to go from cdma to lte?
Sent from the Matrix
You've already tried what I would suggest:
Go to Settings, Wireless/More Settings, Mobile Networks, Network Mode, LTE/CDMA. Then Access Point Names, LTE.
The only time (with HE or K1) I can't pick up 4G well is in my house. I go outside and it picks it up, but inside will drop to 3G.
If it's an issue for you, then you may want to revert back to whatever Ice Cream Sandwich ROM you were using before, such as HE, G7, or F2.
If you did a backup in Clock Work Recovery, then you can just restore it.

I had to exchange my phone with Verizon
I just nandroided back to ICS, it's acting very funny.
I can get a LTE signal now but ONLY by going to an app (Phone Info) and switching from LTE/CDA/EvDo to LTE only. Also after switching to LTE it still only shows a signal of -120dBM (while still showing an LTE icon), after I switch the screen off and then back on it shows bars and the dBM starts to register normally.
I can still not get LTE to work regularly with CDMA/EvDo and haven't seen it switch to LTE once without me changing it.
I've tried the K1, JB and HE stock radios.
Would clearing all data before doing the nandroid do anything?
bumping
Fixed the problem, I got everything cleaned up and back to stock (using the guide that's pinned in the Q/A forum and went into Verizon, they gave me a new SIM Card and I can now get 4g LTE again, still on stock, will be nandroiding when I get out of class.
If there are any probems after the nandroid I'll post them here, if not everything went according after the nandroid.
So if anyone in the future is having this problem it could be the SIM card.

I was just going to recommend trying the Re-provision code (only works on early ICS builds), and if that didn't work getting a new SIM card.
Glad to hear the SIM card fixed your issues!
I had the same issue. But a new sim didnt fix the issue. Replacement on the way.

So, I got a AT&T Skyrocket s2 i727 from amazon. its already unlocked and i noticed it was stuck on edge speeds when i put in my sim card. I researched why it was on google and came across this site, which i have to say is amazing!. i have read every topic there is about how to root/unroot, flash roms, radios, kernels, etc. over the last i dunno, week or so. So i decided to give it a try since everything is step by step, which im not illierate towards, i understood what it all meant. first thing i started out with is odim and flashed the cwm touch for the skyrocket, which was easy. i then researched some more and seen i wanted to make this phone on tmoblies 4g service, which here in iowa is called IWireless, anything tmoblie works with this since they are an affiliate of tmoblie. I started out downloading all the radios, which i have:
cwm-tmob-kl1-radio
Telus_SGH-T989D_Kj3_radio
Tmo_SGH-T989_KID_radio
Tmo_SGH-T879-UVLG3_radio
Tmo_SGH-T989_VK1_radio
Tmo_SGH-T989_UVLE1_radio
Blaze_4G_LB7_ICS_Radio_MOD
so as u can see ive got pretty much all of them. then i found which rom i wanted to use, i downloaded CM9 and CM10. for the CM9 build i seen the best kernel for it: InstigatorX-CM9-Kernel3-v6.0.3. also downloaded the gapps for each cm build.
then i followed the instructions the CM team left, backup, factory reset, format, install the radio, then cm os and finally the gapps.
I did all this with each radio and each cm, everything. no i did not brick my phone im alot smarter than that lol. whenever i try a radio, usually im just stuck on the edge speeds. i go into my settings on the phone and it wont save me selecting the lte/gsm/wcdma, just stays on the wcdma preferred....when i did each radio i started from fresh, cleaned everything out, even tried the davlik wipe in the advanced settings in cwmtouch.
so i read in other forums that ppl tried to flash over radios. that didnt work, i was left with no signal at all.
i still have the imei number on my phone when i dial *#06#, so i havent lost that, but every radio i use my baseband version says unknown.
also when i enter the service code in for cm10 and cm9, it wont save my selction of what bands id like to use....
so any help here would be appreciated...im losing my mind over this and it sucks...thanks for anyones help, i need it.
Edit:
switched back to stock ics from my recovery, installed the blaze radio, showed i had 4g, but had no bars. i called someone and after i called them it went back to edge. went to search for networks and all i can get is E again. under settings it shows im on edge 2....so im close but obvisously not close enough. i live in a major city here in iowa and i live a few blocks from a wireless tower...any ideas?

Flash a T-mo radio that gets you on the network, then look around and find the proper APN settings for your provider. You will have to go into the APN settings on your phone and create a new APN with those specific settings for it to work properly. I am not sure what those settings are for T-mo but you should be able to find them with the search feature.

so ive went back to the recovery, which the phone was set at before everything, flashed the radios of blaze and the uvle1 and it shows i have 4g but it bareley even runs. also each time i flash a new radio my apn settings are there, iwireless automatically downloads them to ur phone when u turn it on, and i verified the apn settings with another iwireless phone, an alcatel 995(4g phone). and now i can send a text message, the other phone receives it but the other phone doesnt receive mine. any other ideas? im going to try flahsing all the tmo radios to the phone and see what i can do. also is the radio and the modem the same thing? do i need to find a tmo modem and flash it on there and then a radio?
EDIT: nvm radio and modem same thing it seems like...lol. anyways ive tried the other radios, i completely lost signal with them as to they wont work. does anyone have any other radios that might work? i dont care if it gets 4g just at least 3g lol. im just geting tired of working on this and about to give up this really blows.

Modem and radio are same thing. Other than an APN issue I know of nothing else other than a #*number combination to enable lte settings. I am not sure what that combination is though as I live in a not-lte area and have not needed it. You may want to search the SkyJB thread as I think it was discussed at length in there. And I would try each and every one of the t-mo radios/modems as you might actually find one that works to enable 3g/4g in your particular area.
My phone was working fine after flashing it to GB Rom I was getting 4G data on it. After Flashing to CM9 I only get 3G, My BT works fine everything seems to work great the ROM is awesome I just cant get 4G any help would be great!
Check your modem in 'About Phone'. LB6 only shows 3G but you get 4G speeds. Other CM9 modems will show H instead of 4G.

I looked under About Phone and there is nothing that shows the modem version, I did try flashing several modems though. I never had one show "H"
always 3G, What modem would be best to run? I appreciate all your input, still learning!
Modem is baseband version.
It says T959VUVKJ6 Also says under status Mobile Network Type EDGE 2 is that correct?

Not a silly question, I realized that the data connection for use only 2G networks was checked. I unchecked it and reset the data connection and there you go 4G. I appreciate all your help. I do have one more question. It seems every time my phone is rebooted the 2G connection sets by default automatically, can I stop that so I dont have to turn it off and reset the data connection every time?

I have the same situation and would like to hear how you resolve it. The check mark for 2 g keeps returning.
--Charley
Three major possibilities:
1) The ROM you're using might have it hardcoded. Change to a different ROM.
2) You might be using a battery saving program that sets it to save power. Remove the program or change its settings.
3) Something else.
