[Q] No LTE - AT&T LG Optimus G

I've been going back and forward from nocturnal rom and the Korean jb port and somewhere in between I lost lte. I don't do anything crazy just wiping and flashing. I reverted back to stock and still no lte. I didn't have time to root and don't have access to a computer until I get out of work. I was sure if this has happened to anyone else and was just looking for some suggestions.
Sorry for the lack of info but I haven't seen any error messages or fc's. I'm currently on software version E97010o.
Thanks for any help.

I totally lost LTE as well 2 days back. And at this point I have tried everything to get it back. So you are not alone.
LG Optimus G E971

Yea this isn't the first time something like this happens to me. I lost WiFi on my skyrocket before after flashing and the phone became too hot. Hopefully I find something on the web. Thanks for the post.

So I got my phone rooted and fix permissions. I knew that wouldn't do much but gave it a shot anyway.

Ok. I just flashed the international version of jb and LTE is back. So problem is solved for now.

Possible fix for no LTE
So I've had this same issue where I lost LTE after flashing the Korean JB port and then moving to the Canadian version. I've worked on it for a couple of days and came across this possible fix in a post. This worked for me and now I have LTE back!
Go to your dialer and get to the service menu. 3845#*970# lte-only- Modem settings -Rat selection- automatic, or lte only
I chose automatic and after it did my LTE came back instantly! I haven't been that happy in a while.

Thanks. I tried this and it works on the JB international versio but it doesn't work on ATT stock ICS.

That's because the stock rom doesn't have the setting. In slick Rom you can change one line in build.prop to enable from disable and it will show up in wireless settings.

Calling all Canadians! Bell Telus and Rogers users.

Alright so ill start this of by saying, Picked up my note today and loving it so far. Got it rooted thanks to Da G and getting ready to get into roms.
Anyway im making this thread to see if anyone else has tried anything out on the non-AT&T notes(i.e I717M and what not). So far from what i have read people are developing mostly for the AT&T model and saying its not for bell rogers or telus. Now I have been in the samsung world for a while and when it comes to my galaxy there was always ways around this.
For instance most of my ROMs were made for the international version not my bell version. But as long as I kept a copy of the bell modem on my phone i could just flash that and the ROM worked great. So does anyone have a copy of the bell telus or rogers modem for the note? or know if there all the same?
Another example in the galaxy s world was the captivate(Same soft keys as our phones). A person with a captivate could flash an international ROM as long they made a soft key fix when they developed the ROM.
One of the main reasons I ask all of this is because i see so many N7000 ROMs up and running and am wondering what will and wont work.
Look forward to hearing from you all

Bell note here. Been. The at & t roms with no problem.
The only issue that I have is the Yellow Pages crap that appears in my contact list as well as at& t bloat depending on the rom. Easy enough to deal with though.
Aside from that, it's been perfect.
Currently on Team Perfection 4.0.4.

I forgot to add that I haven't had any issues with data speeds at all.
Also, Don't venture into the N7000 roms because they will not work.

The N7000 ROMs can hard brick your phone since the hardware if the two models are completely different. AS Far as ROMs go, most are based off the AT&T software simply because that's the only ICS leak we have available. But you can use any ROM for the i717 on your Bell Note. I have a Bell Note and flashed almost every ROM and never ran into any problems. Also, Ruth the help ofa lot of people on this sure, I've made stock images of the Bell, Telus, and Rogers Notes so we can always go back. Best if luck and don't hesitate to ask anything.
Thanks for the info, I get mine today and was wondering the same thing.
Yesterday I flashed my Rogers Branded Galaxy i717 with Bell Rom and Kernel and have not 1 issue. I chose to flash the rogers i717 with Bell because I use bell mobiletv and this was the only way to get this particular app to work. Again not 1 issue with data or anything else.
No Rooted device either. Just flashed using ODIN.
I'm currently running the UCLE2 Rom on my Rogers i717. I've noticed that I am not getting LTE where I should be. And GPS connectivity is shoddy at best.
I have a second i717 which is stock that is with me to compare (family member).
I am going to flash the Rogers modem to hopefully correct atleast the LTE issue. Anyone know if this would improve my GPS connectivity as well?
For a number of years I have been buying Canadian phones to use on ATT. Canadain ROMs have less restrictions than ATT. For instance tethering and NFC are not locked. Also after rooting my Roger's Note it took under a minute to remove the Rogers branding. (all except splash screen) I was left with a fully optioned unbranded ROM.
I did want to try the stock UCLE2 ROM out of curiosity but I thought it would not install because my phone was not an ATT I717. How did you install it eugenekim618? Personally I would rather wait for the Rogers ICS version. Keep checking everyday to see if it is available.
I have tried quite of a few of the ROMS on here with my Bell i717M, no problems at all so far, other than the "android.phone has stopped working" at startup, I don't know the cause but it only happens at boot.
DO NOT use N7000 roms! But all of the AT&T stuff has worked great for me.

I followed the posts in the Dev section to Root the phone.
Then installed CWM.
The picked a ROM I thought was good and followed the instructions in it's respective post to install.
I've done a lot of ROM installs for the Dell Streak I used to have and for a Sony Xperia X10.
So I am not totally unfamiliar with the process. Just a matter of getting used to the delivery method for each manufacturer. And then, dealing with the quirks of a ROM that is not 100% for your carrier. Goes with the territory, right?
I tried to read all the posts in a given thread as much as I can.
So you are saying you didn't install the one click odin stock UCLE2 ROM?

No, that doesn't work for non AT&T phones I believe. I tried it, and ODIN recognized the COM, but failed to install. From my readings, can't do the one click install on Rogers since it's not a Rogers ROM.
all custom roms should work no problem, ive flashed tons on my unlocked bell note.
its the stock odin files when you want to make sure you get the proper device.
Hey guys Ive flashed pretty much all the roms I can and some I cant lol. So far my experiances have encountered a few setbacks but nothing substantial and allot if not most of the bugs and glitchs occurring in the first & second gen of roms have been fixed or patched.
As far as roms go as was already mentioned as long as you stay away from n7000 model roms and stick to i727 youll be ok. With at&t roms I always seem to have signal and gps issues. Generally tho I find my signal problem will clear itself up on its own and I believe is actually just just caused by the fresh software 'settling in', even though my signal appears low or fluctuating speed testing always shows Im getting peak d/l & u/l speeds. If the signal doesnt seem to improve flashing the Bell stock modem via cwm always does the trick. Gps usually works great, very fast & accurate, when Im having location issues I use the 'faster fix' app from the market, I dont know about anyone elses experiance but allot of the times theres a problem the gps server isnt set to the normal 'north america pool' but servers Ive never seen before or set to an 'international pool'.
All in all besides signal headaches the only other recurring problems are the inherent and unpredictable random force closing of system apps. It can be pretty random but I find a few constant trouble makers to be at&t software update, android phone. At&t update can be disabled easily under applications in the main settings or I was able to actually remove it using 'rom toolbox's app manager but strangely not with root toolboxs remove system apps. For pretty much all other f/c problems the remedy is a running of 'fix permissions', there are a bunch of ways/apps to do it and Ive found using 'rom manager' works the best meanwhile rebooting into recovery and fixing permissions from there will actually cause more problems.
Ok so those are the most recurring and annoying issues Ive had to name a few but the list is too big to write merely because Ive tried just about every rom right from the sketchiest unstable first releases and everything in between lol so feel free to drop me line if your stuck on a problem cause I might be able to help.
But before I end this novel here lol I just flashed the new 'OnlyOne Beta2' rom from the development section and it runs great. The rom is super stable, very fast and features both fully functional S Voice app and fully functional S Notes app. If you havnt tried S Notes yet its awesome the new functions and abilities totally blew me away so I highly recommend you give this rom a try!

If you had LTE before and lost it through flashing a custom ROM or whatever then try changing your APN to your Carrier LTE network. If you never had LTE when you bought your phone, probably the seller gave you a wrong sim. tell her to give you a 403 LTE capable sim, the 401 is only 4G.

Thanks for the tip. But I got everything running again. I did have LTE to start, and have a LTE sim card. The *#2263* certainly helped. And Flapjaxxx's GPS tools in his ROM helped me get the GPS back up to par.

ok now I just lost my LTE after flashing new ROM from Seraphim Stratosphere. How did you get it back. I factory wipe everything and flash Rogers modem and it doesn't work. How did you manage to get LTE back? btw I have a Canadian Note with Rogers. the Saurom ROM was canadian and I had LTE too.

Try *#2263#
Then force select LTE, and select ALL. That should force the LTE connection. So watch the connection bars. You should see a loss of connection, then reconnect on LTE. Once that is established, do the code again, and just select automatic.

When I try dialing it, it says error can't find USSP or something like that... What does this mean?
Just to be clear that im doing the right thing. I go to the dialer and punch the code *#2263#. How do I "force select LTE"? will something popup for me to select it or should I go to settings/ wireless and networks... I don't have those options in "wireless settings", I only have APN settings...

[Q] 3G not working anymore please help :(

Hey guys I'm on Homebase 4.1 ROM. Phone is unlocked and rooted, android version 2.3.4. I haven't been on these forums for a while since everything has been working great until now. I didn't miss not having 4G data due to being unlocked, but recently Sprint started working on upgraded their towers in my area. We lost 3G data connection for a while and this was supposed to be normal due to the upgrading going on. The problem is that the upgrade is over and everyone else in my family has 3G working again on their non rooted crappy phones, but my 3G never kicked back in. Before I factory reset everything and start messing around with different ROMS i just wanted to see if anybody could point me in the right direction on what I could do or what the problem might be?

try dialing *228 and see if that helps. also try dialing *#*#info#*#* in the dialer and go to phone information. scroll down to the drop down menu and trying putting it into EVDO only mode. see if it picks it up.
Did you have 3G on this rom before the upgrades? Some roms were having 3G problems over the last couple of weeks, but new versions have fixed it.
If that is not the issue then you can try ##DATA#

try to re flash ur rom again..hope it fix i think..
Fixed
It was definitely the first ROM i was using being broken. Moved to MOF locked version and everything works fine. 4G is nice too. Setting up all my home screens the way i like it again was a little tedious but oh well.

[Q] 3G only - disabled LTE on my Note2 by changing mobile settings in 4.3 ROM

At one point on a 4.3 (CM based) rom I was fooling with the mobile settings and I changed from global to CDMA/LTE. It seemed sensible at the time, but ever since then I never see any LTE, only 3G on Verizon. Oops! It's been months too. The thing that kills me is that somewhere in one of the ROM threads I saw a mention of this very same issue, advice to never change that setting (oops), and most usefully a shell script to fix it if it happens. I've been looking to find that post again and it's like I imagined the whole thing. Wish I could just find that again.
So, as a last resort, I'm begging for your help.
Does anyone know how I can get my LTE back? I've reflashed ROMs, reset my phone, wiped my cache and all sorts of other things. I even restored to my oldest backup of my Note 2 from when I rooted it the first time, so I'm rocking TouchWiz VRALJB (still rooted) right now. Do I need to bug Verizon for a new LTE SIM? I really don't know what to do here.
happened to me on my LiquidSmooth rom too. if you long press your LTE button from the pulldown panel toggle to go to Mobile network settings, click network mode and make sure it's CDMA+LTE/EVDO.

Thanks for your speedy reply! I tried swapping mobile settings around (it was already CDMA+LTE/EVDO), and unfortunately it didn't help me.
However I went to the Verizon store (with rooted stock MC3) and asked for an ISIS compatible LTE SIM card. I thought it might help, and the $50 offer is tempting. The process of putting in the new SIM jogged my phone's ability to find LTE again which was great. Unfortunately, the ISIS app embarrassed me a little and said it couldn't run on a rooted phone (even though I disabled root in SuperSU). All and all, it was a very good day.

Modem/Radio resets after phone calls.

Hey guys, tried searching everywhere for this answer. After every phone call my radio resets each time. Started happening on CM11,then on ART MOD rom, and so on. Even tried flashing Stock LG ATT 4.1. I tried flashing different modems, stock att, hybrid , lte hybrid and so on. Any other ideas?
Thanks!
AT&T doesn't support voice over LTE. Every time you make a call, it switches to H+. Its supposed to switch back to LTE after hanging up. I had issues with it under artmod and the other kitkat stock bases.

Did your modem reset to were it would show no service and no data, then turn back on to H+ then LTE?
Mine will do this ever so often.
No, it was instant.

My question to all the developer here... can anyone help me please? i have LG Optimus G E970 at&t and having serious issue as it is not detecting sim network, everything is running fine except sim network. I was on stock and all things running fine but i installed 4.4 kitkat rom from this link: https://yadi.sk/d/F7yqEV7yaFk8V
then my network not worked, i restore back to stock 4.1.2 but still same problem, no sim detected, i showed it to market developer and they said it is hardware issue while i told them its happened due to installing rom and one have tried on it all things as he was software engineer but no luck, then i gave it to repair shop and they changed its sim jack and insert everything perfectly, but still no network! though one changed in that now when i put sim its not showing but when i eject sim from the jack while phone on the message comes "Phone will restart to use GSM network" and then phone is restarting but same problem , no sim.....!
can anyone tell me exact solution for this? is it really hardware issue or software related? i m stuck up and spent heavy amount on it and still on risk.... i will appreciate your kind cooperation.... thanks in advance..
I have a temperary solution.. hopr it help
I have the same problem and tried everything I could...
If you are in a city area just flash .48 or .54 nexus 4 radio. You get your sim working and can call...
But this will have bad signal strength in Idea 2g network. All the best.
i'm also having the same problem. after every single phone call, the modem resets and the only option is to reboot it. downloaded the latest nightly and did a factory reset and flashed it but it still was re-setting. going to go back to stock.

[Q] one max on t mobile.

I'm currently using my bone stock untouched Verizon max on t mobile. Looking for a rom that will work well on this carrier, or better than the stock Verizon rom in global mode. I did put in apn settings however mms msg's are hit or miss as well as lte. I get lte randomly, but mostly stay in "h" but the factory Verizon rom won't let me edit carrier code settings (310-260 for t-mobile).
So in the short if anyone has successfully done the switch to t-mobile with their Verizon variant one max and what rom worked the best for you or worked well in general would be appreciated.
Thanks
my experience
I have the sprint version and I am using it on t-mobile. Vipers rom has the best stability and options. You should be able to edit apns and everything on there. I was having issues but I believe mine to be strictly from being the sprint version, which i know i should've found the verizon one, but too late lol.
I was running CM11 and everything was working for me but I had random lockups when the phone was asleep so i went back to using Viper rom.
