Is anyone else experiencing "issues" with the CDMA radio "overtaking" the LTE radio? It's as if the CDMA radio rules over the LTE radio and decides whether or not to use 4G or 3G.
I've had to toggle LTE multiple times after it went to 3G in order to get LTE back.
noticed this as well running 4.0.2 radios, at least you get it back after toggling mine drops it altogether... but I just got my nexus today so maybe I overlooked something

I experience the same, 4G works great, until it drops to 3G. Then it seems to take forever to bump up to 4G again, but usually I have to toggle it off and then back on. A friend of mine can't get 4G to work at all, Verizon has told him it's a radio issue (odd though because they tried his sim in 3 different Galaxy Nexus devices). I'm going to try and upgrade him to the leaked 4.0.4 build this week to see if the new radios will help him, it's too nice of a phone to be stuck on 3G all the time.
I have a rooted Galaxy Nexus with Sprint running ParanoidAndriod 3.55. I think my radios are older and I need to update them. My baseband version shows L700.05 V.FC12 / L700.FC12 which I understand thier are newing radios out to download. I am having issues with signal lose making phone calls and what not. I live in a area where Sprint should have no issues with service wihich I have never had before. I am hoping that updating my Radios will help. Can someone please tell me which one are the newest and the best way to install them. Thanks.

The newest radios (ga02) are in the second post of this thread. You just flash them. :http://forum.xda-developers.com/sho...rcery 5.3-Toroplus ~5/25~(Collectors edition)

You missed the stickied Sprint radio thread in the Sprint Dev sub-forum.

Thanked you by mistake, actually.
4G symbol on status bar is a cosmetic thing... Since LTE is considered to be 4G... and vice-versa

I've attempted to go to 4.3 several times trying different roms (i.e. Slimrom, CM, etc). However I'm experiencing serious data drops when going to 4G to 3G and vice versa. My phone will hardly connect to 3G at all. 4G is stable until I try to switch but unfortunately I have to switch b/c I need it to conserve battery life. Any suggestions on how I can get the radio to stabilize on 4.3?
I assume you're on Verizon? All you can do is wait until we get new radios. No ROM is going to fix a driver issue.
Yeah I'm on Verizon. Why are other people reporting they don't have issues?

This is a known issue with the Verizon Galaxy Nexus (toro). It happens with pretty much any Verizon phone that gets a major (unofficial) update- data tends to break or be unreliable until there is a radio update from Verizon. All the more reason to switch off them and onto a carrier that uses GSM like the rest of the world and US (aside from Sprint).
As for others reporting not having the issue, to put it bluntly, they're likely wrong. If they're being served by a single tower, don't travel much, or are on wifi constantly, they probably just don't notice it. The vast majority of people are reporting this as an issue from what I've read, however.
I haven't heard anything from the toro maintainer- I don't know if he is still actively maintaining the branch. The only absolute way to solve it is to flash back to a 4.2.2-based ROM, unfortunately.
Thank you for your response. Unfortunately the two gsm provider's in my area aren't very reliable. Verizon is the only one with good service in my city. I'm currently on 4.2.2 still. I couldn't stand the data drops so I switched back.

Why does the ROM require different radio drivers? It seems like that would remain the same regardless of software. Does 4.3 Android make different calls to the radio drivers or something?
First let me apologize if this has been answered somewhere else before, I've read at least 15/20 different threads that had an issue similar to mine but none of the fixes suggested in those threads were of any help. I cannot seem to find anything about LTE working perfectly on someone's phone then just stopping working; every thread I have found pertains to people losing LTE after flashing a new ROM or while traveling to different cities.
I have a SGH-T999L and am located in Chicago where there T-Mobile does have an active LTE network in place. I have had my phone for almost a month now and have had no problems; I have flashed several different ROMs onto it (cyanogenmod, liquid smooth, pacman) without issues as well. Early yesterday morning though my LTE suddenly stopped working. I have not updated the device or changed anything on the phone or ROM. I haven't even installed any new apps in a few days. I first called T-Mobile, they said their network is working properly in Chicago right now. After determining it wasn't a problem with the towers, I tried reflashing the modem for the device (I got it from this thread: http://forum.xda-developers.com/showthread.php?t=1880987) to no avail. Even though the IMEI was showing up properly I even did a NV restore to see if that would help, which it didn't. I then flashed the stock ROM (UVAMB7) to see if that would fix anything, however the phone is still not picking up LTE. I have even tried doing the diagnostic codes *#197328640# and according to that, the LTE radio is turned on and working properly.
As it is right now, the phone will go through periods where it cannot find any data signal for about 5 minutes at time then HPSA+15 turns on, which also confuses me as Chicago is HSPA+42 market and if I turn on my regular SGH-T999 and set it next to my SGH-T999L, it is able to pick up the HSPA+42 without a problem. Also, the phone hasn't been dropped or anything so I don't think it has to do with physical damage to the antenna or anything like that; literally I had my phone plugged in charging on the table all night and the next day the LTE had just stopped working. I have tried everything I can think of, if anyone can give me any help with this issue it would be very greatly appreciated

You might odin back to root66 and see if that works. If not, triangle away and warranty it out.
Hastily spouted for your befuddlement
start a downliad, then go to Settings, about device, status. what does it show under network type? roms dont always didplay things as we are used to. this will show your true connection.

When I do that, it shows up as UMTS until I start downloading, then it will connect to HSPA+15 then go back to UMTS once the download finishes. The phone network type used to show as LTE before I had problems, sometimes it would switch between HSPA and LTE while I was downloading or loading webpages but it would still show LTE under network type. Now it seems as though it isn't even connecting to the LTE at all.
i wouldnt worry about the hspa 42 so much. it may be the lte devices dont use it in order to save bandwidth for non lte devices. just a theory.
as for lte, you can try flashing the T999N modem to see if it helps. otherwise id agree with the other suggestion. odin flash your root66 firmware and see if it still happens. if so it may be hardware related.

Thank you, I will try flashing the modem. As for reflashing via odin, I tried doing that and the problem is still there so if flashing the modem doesn't work, I'll have to call Samsung for a warranty repair . I just wish I knew why it randomly decided to fail so I don't accidentally kill any other devices lol
Well, flashing the modem didn't work. Hopefully Samsung will be able to repair whatever is wrong with it. Thank you so much for taking the time to try to help though, I very much appreciate it
it could be something as simple as an antenna becoming disconnected, or something wrong with the radio itself. but once you are full stock, and still having issues it pretty much rules out a firmware/software type issue. Leaving the most likely cause to be one you probably couldnt fix.
just to make sure tmobile was correct, id try to go a few miles away and see if it connects though. just to be thorough.

This is a quick couple of questions for anyone out there that may have a solution. I'm experiencing LTE issues. These issues happened after my note was returned from repair and installed 4.3 OTA. Now, this was a while ago and I recently rooted my device in hopes of fixing the LTE issues, but to no avail. 3G works great but 4G will work sometimes as in: I will have signal but it is very poor in some instances. I've checked in with support and they are of no use. Did all the pertinent resets and reactivations. So I figure the LTE card thats embedded might be the problem. I've checked the APNs and activated the device via WiFi ONLY to see if that would help. And also after my phone was returned I noticed in About Device... in Hardware Version details it has---- Not Acti---- instead of the usual L900.06 or whatever. What may that be? Cause it seems strange in my opinion. Either way 4G LTE works now after rooting and rom'ing than before on stock 4.3 and 4.4.2 where switching to 4G would basically do nothing even though data was being " sent:recieved " . Now 4G works but still loses connectivity randomly when my wife has her S3 and 4G is flawless in the same damn location. LOL. So I know it can't be the towers. Any help is appreciated.
