Hey guys,
I followed the instructions for ICS flashing with my LT28i, had some ADB troubles but ultimately ICS installed fine. Now trying to flash with .111 baseband, Flashtool goes really fast through its process, says flashing is complete. Tried it twice already, and when i boot the phone back up an LTE option does not show up (gsm/wcdma/wcdma preferred+GSM). Phone connects to data and only shows me H icon.
are u in an LTE area? if so try a speed test.. u should be getting LTE speeds with that baseband... just b/c it doesn't show in network doesn't mean it doesn't work. at least thats what i gather from the other threads. i'm not in an LTE area so i can't test anyway.
Definitely getting HSPA speeds. Back on GB (.111) i got 40Mb down and 11 up, now getting 14D 3.6U. Maybe i need to score some 3rd party app to force bands?
Here's a fix for those who have the issue. Dial *#*#4636#*#* to get to the hidden service menu. Then go to phone information. From the list select LTE (preferred)/WCDMA/GSM. That should fix the issue. If it doesn't select LTE(preferred)/WCDMA/GSM, just turn off radio then turn it back on and select LTE(preferred)/WCDMA/GSM. If it all works, you should see 4g icon instead of the H next to the signal bars.
thanks for the responses. when im on that page what i see is LTE(preferred)/WCDMA/GSM. H icon next to data connection. Whether the radio is turned on or off i cannot change that option in order to change it back. Do you know if the config menu (the one that shows you active bands like LTE_BG5 and stuff) should actually say LTE, or is that just a soft-config? Those seem to be gone as well.
thanks

it should say 4g. not lte. It takes a couple of tries to change that option to LTE(preferred)/WCDMA/GSM
UPDATE: reverted to .111 then flashed .233 without baseband, 4G working well.

hey, im having the same prob. i flashed .111 then .233 like you did but am still having the same issue. my network type shows hspa:11, but does that indicate the network in my area?

Did you do a full wipe before flashing .111? If not try that.

i actually solved it; turns out the apn was blank. all i did was put in the apn that spectre51 provided (thanks spectre) and lte worked after refreshing the network lol.
Flashed touchwiz jellybean Rom. Had no lte. Flashed back to rogers original 4.0.4 and no longer have lte or 4g. Do I have to get into an lte area before It registers? I have my tab with me and it's getting 1 bar lte 4g in a weak area. Please help.

Go into your Mobile Network settings, check "Access Point Name" and see if you're on the LTE apn.

I've had the same experience with three other roms I've flashed on my roger gs3. I have been through apn settings on all of the roms, but I still dont get LTE. When I recover the stock rom it goes back to 4g/lte every time. So, I'm sticking with the stock rom until there is a definitive fix. I'm nowhere near good enough at this to figure it out myself.
I suggest, if you want to keep receiving lte service, that you restore your stock rogers rom.
From what I've been reading on xda threads; it seems that this problem is central to the at&t/rogers/bell phones.
Roms I have tried:
d2can OTA keeproot
aokp_JB_d2att-ota-eng.task650-ktoonsez-10.3.2012c (this one is so bad ass; I might just put up with no lte)
Liquid smooth d2att jb v.2.0
NexusMod-Triune-II-(UX)-20120918-NIGHTLY
Are you basing the no lte status solely on the icon in your notification bar, or have you ran speed tests to confirm your network speed?
speed tested everytime

No, unfortunately, when experiencing these 3g/h+ instead of 4g/lte problems, on the flashed jb roms, my download speeds are consistently under 5mb/s. When restored to stock rom they go up to almost 10mbs on 4g. I haven't been able to test the lte speeds yet because rogers towers somehow manage to miss my street, but are covering the college five blocks from here. I'll test again next time I'm on campus and see how they both fare.
There seem to be so many variables involved. I'm just trying to eliminate them one by one, so as not to confound the results.
I was thinking that the aosp roms don't usually have an lte icon.

I had to give up on ktoonsez &task rom and go with CM10 nightly. This is after trying out cm cfx official rom, to no avail.
I was able to get 4g with cfx, task 650&ktoonsez,but only for a short time then they would automatically either lose signal, or switch to a different APN all together. Now I have around 13 mbps on CM10 with H+. I'll settle for that instead of sketchy hit or miss with the others. I'd like to figure out how to fix Task650&ktoonsez rom. I prefer that one so far after playing around with them all a bit.
Ok so I have an unlocked LG Nitro HD with custom ROM (CM10) and it has a very weird problem. I've tried two different AT&T MVNO SIM cards (AirVoice and Consumer Cellular) both have the same issue. My data signal keeps changing from H to H+ and occasionally to 3G like every few seconds regardless of where I am using the phone even outside. I don't understand what the problem is. What could be the issue?

Data does work but it seems to drain the battery with the networks constantly switching and on occasion I get a "No Connection" screen on certain apps, I guess because if I open an app while its swapping networks the app cant connect. It's strange.

They are set up properly.
I had another odd problem, just a few minutes ago was texting someone and all of a sudden phone froze while vibrating then restarted! Don't know if that's a bug in CM10 or what, maybe the network swapping is as well.

Maybe make a backup of your CM10 and try flashing a different ROM not based on CM10.

I think this is the same issue that I recently fixed in quattrimus. I will try to get the fix included in the cm kernel soon. You might try my Rom to see if the fix works.

I tried installing CM9 and it appears to have fixed the problem, the phone doesn't try to connect to the H+ network anymore, only the H network and seems to stay on it so far. I did see it quickly go over to the 3G network but it doesn't appear to be causing any issues, it went right back to the H network. However, I really wish the CM10 ROM worked right, as CM9 is so old...

CM10 is snappy and oh so buttery smooth, I give you that. On another note, did you try any other CM10 variants? I'd give tdmcode's AOKP a spin. He says he might have fixed that problem you were talking about in his build.

I downloaded the CM10 ROM. It seems to behave slightly differently. It stays on H normally, but when I start to do something with data, it will go to H+ until the data loads, then go back to H. So far no disconnects, I'll keep you posted. Right now I have very limited data, I'm switching to T-Mobile as soon as UPS decides to deliver my SIM card (just found out they have a 1900MHz HSPA+ network in my area!) I'll be able to test it better then, but for now I'm trying to stick to wifi, especially since I wasted so much data tonight playing around with this stuff, lol.

Ditto... H and 3g are subsets of each other. Namely they can handle simultaneous voice and data 4G (h+) and lte can only handle data. So it switches back to H so you can receive and make calls plus it uses less battery. If you are on either 4G techs and receive a phone call while downloading it will automatically switch to H from h+ or lte, this is why. The only way you will never see this is on an AT&T rom where it only has 4G and lte icons.

H+ isn't a subset of 4G is it? I know that the CM's have separate icons for 3G/H, H+, 4G, and LTE.

That certainly is debatable but the US's largest carrier considers it to be, it behaves like 4g, H+ may not be as fast but it is 90%+ as fast in most markets small enough to not make a noticeable difference as far as people's perception and the technology behaves like LTE in a lot of respects, CM is international so it just conforms to International norms so that's why you get H+ AND 4G (LTE) designators.

I Loose network signal anytime i switch to 2g/gsm only
I have tried reboots, resets, tried different roms, all other sim cards have this issue when i use them on my phone, im on the latest radio too. Dont know what to do now..
Any help would be appreciated.
The T989 might be incompatible with the 2G bands, are you using it in the U.S.?

Dont think so, it used to work before, then after some time i would have to turn off the data or reboot before i could switch, and now it just stopped working!
Not in the US tho

Possible fixes for this is flashing the latest radio, I believe it's UVMC6. Works fine with my phone (I live in Mexico and 2G works fine)
EDIT: Sorry, I realize that you have the latest radio, my bad
I remember I used to have this issue too, what fixed it for me is choosing manually my network operator, available in the phone network settings. It was either choosing manually or automatically, I can't recall which one I chose, but it fixed the problem. I now have it in automatic and it works and from time to time when I travel to the US close to the border, my phone cannot decide if it wants to go with T-Mobile or my network (Movistar) so I change it to manual and select Movistar and works just fine, so maybe all you need to do is change from Automatic to Manual, or vice-versa. Hope that can help

Hey,
I tried choosing manually, it did say it was registered on network, but that's it, signal bar remained empty and it still said emergency calls only. At times the signal bar fills up, but saids mobile network unavailable when I try to make a call.
Appreciate your assistance tho
I managed to make a log of when I switch to 2g, If that would be helpful

Wish I could help, but I don't know what to do anymore. Why don't you just stick to 3G? There are some places I can't use 2G so I switch to 3G, I just deactivate data when I'm not using it. I sometimes lose 2G signal too, but that's mainly because I am inside a building with thick walls or I simply don't get 2G signal, happens from time to time on certain places, like my old work place for example. I would either get low signal or no signal at all.
I wish I could help, but even I don't know what to do. Best of luck to you
So, i'm in the UK with my nice shiny OP3 (on Three UK) - I am rooted with twrp, but same applies on stock.
The radio in this phone seems to prefer H+/3G to 4G, even though where i live, i have full bars on both. My nexus 5 always prefered 4G, and the OP3 is set to prefer 4G but 90% of the time drops to 3G/H+
Another interesting thing, if i use the testing menu to force LTE only, even if it's on 4G already, completely stops any signal getting through for a number of minutes until it decides to connect sometime later. I have full LTE signal in my room too.
Is this a radio problem that could be solved in the future with a software update? not seen anyone else with this issue!
FYI, when it is on 4G, it's super fast and stays connected until a reboot, where the whole process starts again

APN Is exactly the same as my nexus 5, and i even added a new one. Same deal.
I'm an IT Professional, just not a developer. i've done everything i can think of. 4G does work, but only when it wants to. My phone is also registered with my carrier correctly.
Bump on this anyone?
I am having a similar problem I guess. I have the dual sims installed and one sim randomly shows no range. Further, the network preference is not the way it is supposed to be - Chose it as 4G and if 4G is not detected it falls back to 2G.

I first put my sim into slot 1 when I first got the device, I was having the exact same issue. I found that the data priority sim, or if you only have one sim needs to be in sim slot 2.

Yes exactly. And even then it doesn't show up straight away despite 3/4 and usually full signal. Sometimes just putting it into standby mode and leaving it 20mins can sort it... Until I get another call lol. Wondering if it's just a software or firmware issue that could be patched. Lte is fine it's just never preferred despite the options being set

APN is not the universal response. Here he faces a problem of inaccurate network type choice, APN is only to have acces to internet through the provider's proxies. It's a radio problem clearly, the baseband is probably to be corrected by OnePlus.
It's really a strange thing to see those network type issues, MMS issues are still present after all those years.

This is what I thought. It's probably an easy fix for oneplus or rom developers. Custom radios are nothing new. Let's hope so anyway!
This is happening to me as well. I'm on three in a strong 4G area but it always prefers 3G it's so annoying hope it gets fixed soon.

Same issue here, have never got it to say 'LTE' for me since I got the phone, best it does is 4G whilst my Galaxy S5 would happily pickup LTE. Just wondering what UK users have there preferred network type set to? Mine is on GSM/WCDMA/LTE I assume that is right as that is what it went to itself and have tried LTE or LTE/WCDMA too.
