Lost LTE

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.

Sorry. Missed reflashing the radio. haven't rooted since installing I've leak. I'll try that next. Thanks

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?

A Question about Unlocking and Rat Locked Radio

I have a Galaxy S II running the UCLE2 ICS Leak, I love the phone but there are many times I'm in a area with a real weak LTE Signal but a great HSPA Signal and times I'm in a 2G Only Area.
I know that the AT&T Modem is Locked so you can't switch off LTE or set it to 2G Only, If I got the Unlock code would that also remove the Rat lock? if not can you use a Rogers Radio on a AT&T Rom?
Thanks

No removing the sim lock will not help i believe the only radio that is unlocked is the rogers KJ7. Not sure what rom your using but some have a selection in the network screen i am using ChimeraVsSkyrocket_Beta2 and it has that option sorry i was trying to get you a screen shot but the usual buttons are not working

So is it safe to flash the rogers radio with me being the AT&T Radio?
If I flash the Rogers Radio with the AT&T APN's Should everything work as normal?
And If I decided to go back to UCLE2 Radio is it you like your basic flash with CWM or would I need to do the Samsung 1 Click to restore the phone to stock?
Thanks so much for your help

Rogers radio will work with att... though signal and speeds will be different. maybe better, maybe worse. its different for everyone.
and it will only work if the rom you are using has the option in it. such as a rogers rom or some other custom roms.
and flashing back to ucle is through cwm. exact same as when you flash the rogers radio...
i'd try the new rogers radio if i were you. it should be RAT unlocked. i get drastically better signal over every other radio (though i am a rogers user).
you may need to switch roms though. if thats the case i'd advise using the chimera rom. since its confirmed to have it. (not very many AT&T roms do.)

The latest rogers modem works with SKY ICS. I flashed it but the signal sucked so I went back to ULALC4(Best for me). Not sure if this is what your looking for but theres an options in your wireless network settings that allows you to use only your 2G networks. Actally has a sub title the suggests it saves battery. Might wanna check it out.

[Q] New to SGS2 727R

Hi all.
I just finished picking up my sgs2lte. Really excited about it. I just finished rooting it and now I would like to install an ICS 4.0.4 rom.
My specs are:
SGH-I727R
Android 2.3.5
Baseband I727RUXKJ7
Kernel 2.6.35.11
Build GB.RUXKJ7
I am hoping someone can assist me with this.
What is the best baseband for rogers?
What is the biggest sdcard that I can buy for it? I heard that this device can now accept 64 class10 sdcards, is this true?
Thanks all,
Heeter

I don't think it matters much.
UCLE2 is the recommended modem for most ROMs (Most ROMS will state which modem is recommended), especially the AOSP based ones like CM9 or AOKP. For the most part they seem to be interchangeable.
I have used the UCLE2 and UCLF3 baseband modems with no issues (I believe UCLF3 is the RAT unlocked rogers modem..).
Right now I am using the latest AT&T modem UCLF5, with CyanogenMod 9 (7/02/2012 nightly) and it seems to work just fine.

Are you able to get 4G with your setup?
Thanks for your response, Rabidsmurf
Heeter

Yes, although the phone is somewhat misleading, at least in CM9
The icon will show 3G until in use when it switches to H, I assume this is for power savings or something. Download the speedtest.net app to confirm. On 4G i get around 8Mb/s down and 2.5 Mb/s up.
Additionaly what Rogers calls 4G is HSPA+, if you go to About Phone > Status under mobile network type it should say HSPAP:15 (That is HSPA+ 4G on rogers), conversely 3G is UMTS:3. My phone flips between the two as I mentioned when not in use or in use, could be a ROM specific thing.

Well, mine was saying 4G before the rooting with the factory settings,
But it says UMTS:3 on there now.
I will install CM9, maybe that will make the difference, I just installed the ATT UCLF5 radio, still 3G
Heeter

What ROM are you using?
If it's SKY ICS, in my experience it will always say 4G no matter what (Unless it's LTE maybe).
If you see UMTS:3 try to open an APP that has constant network demands, it might switch while you're looking at it in the status to HSPAP:15, sometimes it's tough to catch it as the phone seems to go idle as soon you go into the menus
I am also in Edmonton by the way.

Hi Rabidsmurf
Was mistakingly on the Chimera rom, but I just reformatted everything and now is using this SKY ICS 4.2F6 with the UXCLF3 radio, now I am getting the 4G signal
Thanks sooo much for helping me out.
Right on, cool, fellow Edmonton dude.
Heeter

No problem.
I was also going to suggest reviewing your APN settings if all else failed. Found a typo earlier with the APN that comes with CM9 rom (caused MMS to not work), guess that's why it's still an Alpha.

lol actually its at the level of an RC, but I digress

I'm using the I727RUXLF3 Baseband on AOKP Build 40 in the Edmonton area as well and it's running great. I see the same behaviour with the switching between 3G/H signal.

No 3G / EvDo

For some reason I cannot connect to 3G. I can only get 4G or 1x. I've been running cm10 for awhile and I've switched back and forth between different ROMs including back to stock and other TouchWiz ROMs. I've not really sure when this happened because I didn't really notice at first, seeing as how I'm in a strong LTE area. I've tried using phone info and using the settings in cm10 under mobile networks. The strangest part of it is that in phone info, if I set it to EvDo only, my bars go empty.
I've updated to the latest modem, and like I said, I've tried different ROMs and even different kernels. I've used Odin to get all the way back to stock unrooted and everything. I can't figure out what could be causing this.
I lost my IMEI weeks ago but got it back so I don't think that's the issue.
Any help that I get can get would be really appreciated.
Thanks

No LTE with Custom Roms?

I know the skyrocket I727 supports LTE. With stock firmware LTE is not a problem. But when I put any custom ROM it no longer goes to LTE. Is this normal or is their a separate download for an LTE radio in these custom ROMS?

This is not common at all. Check that your apn settings are correct. And you have the recommended radio. What rom are you using?

I have tried slimbean superlite and a few others. My radio is well I can't seem to find that. My baseband version is i727ucll3 I use CWM touch...When I go into mobile networks is says HSPA:10 and that's it.

Radio or modern is the same thing as baseband. I'm not familiar with the slim bean rom so maybe someone who is can give you a better answer. But in Mobil networks, apn on the superlite rom I have three options with one being lte.

If you're using a rom like PA, CM10, AOKP and probably Slim Bean too.. 4G=LTE.

Do I need to install a new radio? I just ran a speed test and I am getting only about 2 megs down, where before on stock it was like 15 megs down...

You have the LTE Apn, correct?

OK don't laugh, but I have no idea what APN stands for where should I like for that? Where would I get one Bear with me here I'm not a complete NOOB I can do some stuff Thanks for the help too...

Settings, more, Mobil networks, access point names(apn)

Ok I'm their but it will not let me choose anything except HSPA:10 when I try to choose LTE it reverts back to the HSPA

Can you take a screenshot of this screen.. it'd be easier to see what's up?
Edit: Also, what rom are you on now?

The radio you have is the right one, but I'd re-flash it. See vincoms stickies in the development section. He'll have the radio download and how to do it.

Download the ucll3 radio from vicoms sticky and flash it. You don't need to do any wipes and its not going to muck anything up. It'll take care of your problem.
Sent from the short bus

Have you run a speed test lately? As said, many custom ROMs don't have an LTE icon; 4G is LTE, H+ is what AT&T considers "4G" in areas without LTE coverage. Running a speed test is an easy way to tell. If you're getting LTE speeds when your phone says 4G, you're on a ROM that doesn't show an LTE icon.

Do you have the wrong radio installed? i know that when i had ull3 installed and needed ulck4 it didn't show i had service at all, but it worked still

Have you tried opening dialer up, entering *#*#4636#*#*
Go to phone information, scroll down to a drop down menu. Sometimes it'll say WCDMA preferred. Open it and select LTE and your signal should drop and cone back as LTE. After select LTE/GSM and close it.

Are you sure you were on LTE in the first place? AT&T is kinda misleading with their branding and calls HSPA+ "4G" whereas LTE is "4G LTE".

I try flashing pacman rom and my phone is displaying the 4g logo. In the pacman rom thread, I saw a snap shot with
the lte symbol. Any ideas?
