I am using the Energy 3.15 ROM, freshly flashed since last night but I noticed one thing. I can't get the data to enable while roaming. I had no problem with this before since this is at my house and I constantly roam here. It worked just fine on stock ROM and CM7 but for some reason I can't get it to work on my Energy ROM. Also how do I go about updating the PRL, etc.
First off, the Energy romm is not from a sprint phone... it is a port from another carrier. in oredr to update profile and PRL, you need to flash a stock sprint rom. As for the 3G issue... what are you getting? Does it say 1X? if you are roaming thats more than likely what you have always been getting but it was displayed as 3G.
I noticed that I can no longer roam on my Sprint GS3. I used to be able to, back when I was using the rooted stock ROM, but now I just get no signal in places where I should have roaming coverage. I know this because my brother's GS3 will be roaming in an area where I'm showing no coverage.
I tried using the LI3, LG8, LG2, and LG9 radios. Have also tried several different ROMs, including AOKP, FreeGS3, and JellyBomb. I also had manually-loaded PRL of 11115, and then tried updating, which gave me 24006.
I also tried all the different tricks I'm aware of -- toggling airplane mode to see if it will choose a new network. And I've checked to make sure that roaming is allowed and isn't set to "Sprint only."
At this point, I'm thinking of going back to stock to see if that works. I'm not sure what to expect with that, though.
Has anybody experienced anything like this?
As far as I know, you arent able to roam on 3g. If you put the corporate prl on your phone, you can then roam on other carriers.
Oops, I should clarify. I can't roam at ALL... meaning no voice, no 1X data, nothing. It shows the "No signal" icon.
Make sure you have roamimg enabled in mobile network settings

Yes, I suffered the same thing yesterday. Until roam control is fixed I suggest looking at loading of Verizon prl in this situation. It is easy enough on this phone to do it and then switch to a sprint prl when you get back to your home area.
Also check Network settings, are you on "Automatic" or "Sprint"?
I had to toggle data and voice on and off until it gave me are you sure you want to roam message after that it started working.(In roam settings)
Evening all,
I've seen other posts about this, but haven't found a solution that worked for me...
I have a Sprint Samsung Galaxy S3 w/ CM 10.1.2, MD4 baseband, and can't get 4G LTE service.
Settings under "mobile network settings" - data enabled - yes, network mode - LTE / CDMA / EvDo, System Select - Auto: Domestic Roaming, CDMA subscription - NV.
Under about phone - stauts, I see mobile network type - LTE:13, service state - in service, roaming - not roaming, mobile network state - disconnected.
When I turn 4G LTE off, 3G connects and I can browse the internet. Turn LTE back on, and no mobile network.
I've tried rebooting, I've tried flashing the MD4 radio, I've tried reflashing to the stock rom...no success. When I flash stock, I can access 4G but then once I flash CM 10.1.2, only 3G works.
When I was in stock, I did update the PRL.
Seems like all the typical solutions just aren't working...please help!

PRL has nothing to do with LTE...it only updates info for 3g/1x. You should do a speedtest on stock and CM and see if there is a difference. Sometimes, my phone will say 4g, but I get 3g speeds. Try a stable version of CM vs a nightly.

10.1.2 is the stable version, see the CM website for d2spr (Sprint Samsung Galaxy S3). Can't post the link myself since I'm still considered a newb by xda...

Did you do anything after the install and was it a clean install? I'm running your same baseband and have the same version. No problem getting 4g.

Before the install, I made sure to do a wipe first, then installed CM, installed GApps, rebooted and started using the phone. No 4G from the get-go.

Figured it out. Had to update the APN settings for "APN2 LTE internet" and "APN2 EHRPD internet" such that the apn setting was saved as "n.c4.ispsn" instead of "n.ispsn", 4G LTE working immediately after saving.

I just tried this and this caused me to loose data completely... so I changed it back.

What I did was from a stock rom (or one where 4G is otherwise working), downloaded an APN config app from the Play Store. The app saved the APN data to an XML file which I then emailed to myself so I could view it on my laptop. I rebooted into recovery, wiped to factory settings and wiped cache, then installed CM 10.1.3 RC2 and gapps. Once the phone restarted I went to the APN settings and made sure each entry matched what I found in the XML file. This is when I saw the last two entries having the different apn setting and updated both. Your settings are quite possibly different.
Where is APN found and what exactly is the name of the app your using?

Hi, it's been a while since I posted on the forums. I've had a problem with this for a while now, but never bothered to ask you all. i don't get certain types of signal with the stock rom and aosp roms. For stock, I get 4g data, and I am able to make calls while roaming but not while I am on regular 1x (connects but I can't use it). Also, signal is iffy, sometimes it connects/randomly disconnects. For aosp, I get almost no signal, only roaming. I think that I didn't mess up my efs folder, my imei is still the same as the DEX on the back of my phone. Do you guys know what is wrong or how to fix this? I want to be able to use my phone again...
What modem are you on? Firmware or ROM? I'm using NE2 with rwilco's stock ROM and a GSM sph-l900 with t-mobile... I get 3G and 4G (hsdpa+)... before I use to get lte/3g/1x and I use roam control when I'm in an area where I know I don't have a good signal...
Hello, I'm pretty new to the custom rom world.
I am currently using latest Spirit AOSP cm11/kitkat based rom with the stock kernel that comes with this.
Now If i use the ND8 stock rom, there is no problem whatsoever with the ability to connect to 4g LTE.
But for some reason, when I'm on custom ROM and my device turns off for a long time / I disable my radio (when connected to wifi)--I'm not sure which one causes the problem--the phone just loses ability to connect to LTE.
I use two apps:
LTE Discovery
advanced signal status
advanced signal status lets me see if my phone can find 4g lte signal/how strong it is. When the 4g LTE is working, i get signals in -(number)db, but when it doesn't it just says n/a for all the sections.
with LTE discovery I use it to see what type of connection i get-- LTE when 4glte is working, and eHRDP? or evdo rev. A for when I can't connect to lte.
my APN settings are correctly set-- my phone has data, voice, and text-- it's just the LTE connection that gets dropped for seemingly no reason.
My method of fixing this is wiping data/cache/delvik/system, install stock kk nd8, perform SCRTN, make sure data/phone/text is working
then I wipe data and cache, then restore my rom... that is working..
If I restore to a point when lte was not working, lte will not work..
but doing this everytime my phone can't lte is very tiring..
I don't even know where to start troubleshooting this issue i have..
I don't even know if anybody has the same issue.. or even heard of anything even close to this.. please help
