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.

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?

LTE Problems in North Dallas?

Any other Skyrocket users having LTE problems in North Dallas as of yesterday? I've ALWAYS had LTE everywhere I've gone in the DFW area since they switched on LTE, but as of yesterday I don't have LTE, and have data dropouts altogether, at home. LTE still works a few miles away from my home.
I've flashed several Radios and done all of the fixes people recommend, so I'm fairly certain it's an AT&T problem, but AT&T told me they don't have any tower outages around me.

No problems here in Irving. I am on rooted stock UCLD2 leak.

I'm currently on UCLD2 Sky ICS 4.2d-4. I flashed back to UCLC4, then stock rooted 2.3.6 on UCLA3. All of them had the same results, no LTE, data dropping.
I'm in Frisco, it doesn't work at my home, but a few miles west, north, or south it works just fine.

No issues here either... I'm on some ROM... new to the skyrocket, tried 3 different ROMs, and so far hated them all. However, all work on LTE
Any advice on an ICS ROM that DOESN'T look like GB?

I've been having some issues with it in downtown Dallas lately. It will show lte but I get little or no connectivity.

It had to have been LTE outage up north of Dallas. It was spotty for 2 days, like I say in the OP, and then it magically started working again and I haven't had problems since.
I'm using Sean's Sky ICS 4.2d and it is GREAT. My battery life is amazing and it's stable.
As M0D said, I hear really good things about his NexusMod. I'm tempted to try it, but I feel comfy with Sky ICS right now. I like all of the AOSP and CM9 that NexusMod has.

Yea, I'm actually on NexusMod ICS and was very happy to see a ROM that looked the closest to ICS. And glad you posted here M0D. I've been a lurker for my other android devices for a while, but my low post count forbids me to ask questions on your ROM thread, so I hope yall don't mind if I ask them here.
1. Why does the lock button not actually lock the phone?
2. Similar to other ROMs, the AT&T check for the MobileAP... can you remove that?
3. I'm assuming I can use a special dial code to use Google Voice as my voicemail service instead of AT&T, but my previously rooted phones could do it no problem.
4. Not sure what your future plans are, but will you be including the "People" app and the raw ICS phone/dialer app anytime soon?
In general, I like the ROM except for all the AT&T stuff that still seems to be lingering. Of course, if I screwed something up, please let me know so I can get rid of these restrictions. Thanks!

Still working on finding the right combination. Would love to drop Rogers for Wind with a mint second-hand Skyrocket I just picked up. Let me know if you have had any success.
Tried:
1) Juggernaut ROM/Faux009 kernel/Telus i898 KJ3 modem = not working
Juggernaut ROM/Faux009 kernel/T-mobile VK1 modem = not working
2) CM 9.1.0 ROM/Included kernel/Blaze modem MOD = barely working (was able to send one text while I was outside despite being well within coverage)
3) Stock ROM(ugh bloatware)/Stock kernel/Tmo i898 KID radio= best reception so far but still cuts out regularly
Testing in Thorold, near NIagara Falls

So far it's working pretty good in 416.
I am using the Rogers SkyRocket
Slimbean 4.1.2 It has to be a 4.1.2 ROM it seems for this to work with the radios/modems as they are compatible with 4.1.2 and below
It works great and I get to 20M on speed test.
**** This is my current issue and I will probably try a different ROM (I really like the Slim stuff)- I reflashed SLIM over the current Slim and will see if it starts the dropping of modem again.
This is my post from anther thread.
The modem keeps disappearing and I have to reflash it to get a signal again.
The phone will just lose the signal and rebooting etc, does not help it get back. You have to reflash the modem file again. This is very strange. I have never read any posts about this issue either.
carrier- Wind Mobile Canada - AWS network like T-Mobile.
It's Slim Rom 4.1.2 on a Skyrocket.
Modem is Blaze 4G LB7 (T-Mobile)
fourth up from the bottom
http://forum.xda-developers.com/show....php?t=1895400
Everything works great but this issue turned up about 2 days after flashing. I wiped and formatted everything before I flashed the ROM.

I chose this radio because T989 users were saying they got better signal on this than even on Blaze radios. Or something like that. I'd link it but I spent like 7 hours fighting with it, way past my normal bed time, so I hardly remember anything. Here is a screenshot of my phone running the radio to prove it isn't a brick-maker. I also do not know if this supports 3G/4G, because as you can see my tower is EDGE :/

I'm gonna test it here in Vegas as soon it's done charging and nandroid backup. Hopefully, you get 3g/faux-g soon.
Yep can confirm that this radio works with faux-g here in Vegas. It's a little slow right now in the part of town where I'm living but workable. To the OP, radios are important for the type of ROM you want to be using. For example, a GB ROM depends on a GB radio and the same goes for ICS/JB ROMS.

I'd be content with reliable 2G. According to mapping apps there is a whole 1 tower here, 2G, and barely usable. Many times it will show 1 bar and still say 'Emergency Calls Only' >.>
I flashed a T989 ROM to enable Wifi Calling, but I need a new SIM card from T-Mobile (a 'GBA SIM'). It took a while with a bunch of phone tag across T-Mo departments, but I think I finally have a 'GBA SIM' coming at the cost of $0.99. Will report.

My phone reports that the mobile network type is "EDGE:2". I've assumed that this means I am not in a 3G area. The T-Mo coverage map shows the majority of my area as 2G. There is one small light green spot (assumingly 3g?) over my house, but I think this is just an error on the map. Therefore I am unable to properly test for 3G/4G connectivity.
I've also asked T-Mo if there was any plans to upgrade our tower to 3G, and unlike AT&T who would quickly counter with "but we have 3G in your area!", T-Mo sent me to some activist page to start a local rally to convince local officials to upgrade coverage. I guess this is their way of admitting it is, in fact, a 2g tower.
I've also changed my radio back to T989. I'm not sure if it was a radio issue or what but it seems after a few hours the phone would lose service completely. I'm still testing stuff.

What is the average signal strength that you usually get? Also , if I read correctly, you are now using the stock t989 radio on the skyrocket? Which would mean GB?

this radio (UVLH1, 4.0.4 ICS latest T989 radio) is also doing the same thing as the note radio. After a while (3-5 hours) the status bar will show service (2-3 bars, even fluctuate) but the system is "Searching" and calls and txts are missed. Need a stable radio...
edit 2: I guess technically I could just ust the original AT&T radio since I only get 2G here anyway, and T-Mobile is re-farming so 3G will eventually work on 1900mhz., the 1700/2100 is going to LTE like it should, thus our skyrockets on AT&T radio should technically be able to get T-Mobile 4G LTE when its available
edit 3: rogers (I727TR) radio probably better than AT&T for the sake of rat unlocked
edit 4: removed edit 1, just gonna use I727R UCLD2

OK. Sorry that the radios didn't really work out. I do encounter some network disconnects here but not a total dealbreaker. I guess we'll have to wait for T-Mobile. On a sidenote, I am finding I have better coverage with this radio.

I do like T-Mobile but I will watch from StraightTalk (AT&T Sim) and try again when they grow some more here. I need mobile data to work. I wouldn't mind 30kB/s but I only accomplished that once. Heck I'd even take 5kB/s if it didn't take over 2 minutes to establish one connection. I can't even use MMS most the time because it seems to require 4+ (-90) bars of service before EDGE will even establish a connection.
Edit: Got my 'GBA SIM' today for Wifi Calling. Works great on this ROM combo. I just wish I had mobile internet. I may do some tests as I am secretly hoping this GBA SIM has 3G/4G and maybe my old SIM was a 2G sim.
For archival reference in case I go back to AT&T ROMs, and my sig changes, Wifi calling for T-Mobile works on our Skyrockets using Faux123 ICS T989 Kernel for I727 MOD v001 and SGH-T989 UVLE1 Infamous Resurrection ROM

Zefie thank you for moding faux kernel as i use the rom on your signature and the kernel and Telus modded radio for t898d nd im getting awssome hspa+ speeds today i gotted 10mb download and 2mb up.

Buy a Samsung Galaxy Nexus from the Google Playstore for only 349.00. Its unlocked and works with both ATT and TMobile 4G.
That's what I did for my wife and using a Flashed Skyrocket on T-Moile 4G has been flaky at best.

[Q] Flashing T-Mobile radio onto at&t skyrocket

I have a rooted and unlocked at&t skyrocket on jellybean 4.1.2 with very slow speeds, so I tried flashing the radios UCMC1 and UXUMA7 through cwm and nothing has changed. After messing with the APN settings a little my data is no longer working. It shows the bars but I can't get a connection.
I flashed the radio UVLI1 in hopes that I would get lucky but that caused my bars to go away to be replaced by a slashed circle. I flashed back to UCMC1 which is showing the bars, but still no data connection. I have broken my back googling and searching forums on this matter but I can't seem to figure this out. Any help please?

http://forum.xda-developers.com/showthread.php?t=2349914
Don't double post

I think UCMC1 and UXUMA7 are ATT and Rogers radios respectively. UVLI1 is the T-Mobile SGS2 ICS radio, which may not work on your JellyBean rom.
Try UVMC6, which is the radio for T-Mobile's SGS2 Jelly Bean update. You can find it here:
http://forum.xda-developers.com/showthread.php?t=1895400
Results can never be guaranteed, but this is the radio I use, and it has worked fine on every single rom I've tried, Touchwiz or AOSP, even in areas w/o the 1900Mhz refarm.

Can I flash the radio change w/out having my phone rooted?

Your phone must have a custom recovery to flash radio files...

It depends on what you observe using either of these..
Try them one by another and see which one is better (UCMC1 vs UX radio) in signal and data speeds ... Personally I couldn't find any difference in my location ... Both gave me the exact same signal and data speeds (TM LTE).

The UX gave me faster data speeds. Call clarity is about the same. I see 4G more than with the UC radio... I was wondering about the T-Mobile radio
Sent from my SAMSUNG-SGH-I727 using xda app-developers app

T-Mobile radios would give you the ability to connect to T-Mobile 3G using AWS bands 1700/2100 Mhz Band4...And no LTE (or 4G) of course since the Hercules and Blaze (or the note one from TM) devices have no LTE radio chip...
If you live in an area in which T-Mobile deployed their new LTE(and most likely they already refarmed the PCS 1900 band), use UCMC1 or the UXMA7 radio,whichever you find better...Setting the apn to fast.t-mobile.com is essential for sure to get the service...
If you live in an area that T-Mobile is still at their 3G service (AWS bands for HSPA+) use the newest blaze JB radio...
Edit : when you say faster data speeds UX vs UC , any speed vs speed measurement you can share ? probably I didn't give each radio enough testing and jumped to conclude that they have same data speeds !
