S4 Mini GT-9195 3G vs. 4G LTE -Radio Flash? - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hello, I have a i9195 S4 Mini that I purchased through Canada. All of the specs say it is capable for 4G LTE but I have not had any success in getting it do operate on this network or with this setting. I am on AT&T in USA. I am currently running Resurrection Remix 5.1.1.
Two questions:
1. Can I flash a new radio to get 4G LTE on AT&T? If so I know there are radio codes, any any help on the code prefix that wold apply?
2. Are there settings from the phone dialer to make the phone operate on 4G LTE.
BTW...I did try to change the dialer settings some time ago, gave up, put the phone in personal storage and decided to give it a new whirl, starting with asking for some help here.
Thanks.

Getting Straight Talk to work on the Note.

I have been using Straight Talk on my note for a while now and I wanted to get LTE. I bought a new sim card for the LTE and put the APN settings in but it is only working on HSPA+. Under preferred network mode it says WCDMA preferred which I think may be the issue but I can't change it, when I try to it reverts back. It may have something to do with Cyanogenmod 10.2. any help would be appreciated. Thanks
Which Note 2 do you have? Not all the Note 2 have the LTE band so if it doesn't have the LTE radio, you won't get LTE (eg 7100 model). Also, the ROM you have should have the LTE enabled in it.
Thanks for the help, somehow I got it to work.

[Q] LG G4 (F500-L) on T-mobile?

I currently have a Korean variant (F500-L). I have seen a couple of these for sale on swappa and both posts say that this phone will work with T-mobile LTE. However, when I've popped in my SIM, I only get 3G. Does anyone else have any experience with this variant on T-mobile? If you were able to get it to work on LTE, how did you do it?
Enter APN settings for T-Mobile. Google that. Just popping in the sim won't give lte.
i have the same issue.. the APN settings seem to be correct.. but it only shows 3G. Model is F500-L
same here i need help too mine is a f500s lg g4 skt version thanks
Far as I know, phone must support LTE Band 2 and 4 to work on T-Mobile 4G network.
But F500(Korean ver. of G4) doesn't support LTE Band 2 and 4. It supports LTE band 1,3,5 and 7. Therefore a phone will only work under 3G network.

[Q] I747 only getting edge on Cricket -- Plz help

OK so I have a Galaxy Grand Prime (locked to Cricket) that gets 3+ bars LTE at my home. I recently got an AT&T (locked to AT&T) Galaxy S3 (I747) off of eBay to use on Cricket. Since both AT&T and Cricket both use AT&T's LTE network I expected it to work without a problem. However when I put the Cricket SIM in the S3 I can only get 2G EDGE network. I have tried different APNs, network modes, even a couple custom roms. I have no idea what the problem might be.
Any help would be much appreciated
What bootloader and modem are on the phone? Not sure if either of those things will keep you on edge.

S4 mini gt-i9195i 4g USA

Hi. I've searched for months. I'm not a novice, but I'm not even close to programmer... I've a Samsung S4 mini i9195i running 4.4.4 . I rooted as soon as I got it, everything works great except 4g. I'm on tmobile in the USA, and I can't figure how to get 4g operable. Any information would be greatly appreciated. Thanks
Rooted with odin, twrp... su, titanium backup installed, stock rom
T-Mobile LTE won't work on the S4 Mini. T-Mobile uses a very specific LTE radio band (1700 mhz) that is only available on specific (usually T-Mobile branded) phones. You can use 3G and lower with T-Mobile on the international phones, and T-Mobile's original 4G (HSPA+) is just a boosted 3G.

Is there anything you did recently that might have changed why your 3G or 4G signal isn't working? Was it working great before?
