Sprint Reception on Custom ROMs - X Style (Pure) Q&A, Help & Troubleshooting

So i've tried pretty much every ROM out and wanted to post my findings with Call reception,data issues, APNs, etc and see if anyone else on Sprint has workarounds or advice on how to fix issues. On some ROMs i can get data but can't get calls/texts. On others i can get voice and data and hear people fine while on calls, but they tell me i'm breaking up constantly.
ROMs with voice and data, but poor voice delivery while on calls:
Resurrection Remix
AOKP
Turbo ROM
Temasek(i think...been awhile since i've flashed and can't remember)
Roms with data(sometimes) but cant make calls/texts:
PureNexus
DirtyUnicorn
ROMs with working data and good call quality:
AICP
Mokee
TruPureX(yes, i know it's not a custom ROM just putting it here because there are no issues with call reception or data on Sprint)
I believe if we were able to manually set APNs for some of these ROMs we could possibly correct this issue but for some reason the majority of ROMs i've flashed say "APN settings are not available for this user". Does anyone know a workaround for this issue? Please post other ROMs that i haven't commented on or other findings/workarounds

I know this is a long shot since this is an old post, but I was curious if you ever found anything on this? I had gone through a bunch of the ROMs mentioned and had the same experience. The only ROM I have had success with and has been almost flawless is Turbo. Yet I have the calling issue where everyone says I'm choppy and cut out so I am having to switch again. Everything else except TruePure I have had data issues with. LTE seems to drop and then I have nothing, it's almost like it can't hand off to 3g. Then I have no signal at all.
I'd go with the stock ROM, but that just has some horrible lag when operating. If I could pull whatever make Turbo work over to another ROM that would be great, but I've never set anything like that up.

Can it be a problem if you are using a XT1572 or XT1575? Maybe you need to be ROM specific when it comes to your device model.

This is the most annoying problem. At this point most roms I try have everything but 4g.

Two Major Problems w/ TW Roms

Hello,
I've been flashing for a long time and currently I'm running Bionix 1.2. I've got 2 major problems and I have a workaround for each; however I thought the community might know better than me.
The first one is about the signal bars and dropped calls. I live in an area (Maine) where you never experience a dropped call since there aren't many people living. At least with my old MyTouch and stock Vibrant, I never had one. So almost once a day I drop call and see the all the signals gone. Sometimes, I see signals but there is no data or GSM connection since I cannot login to GTalk and other services (FB, twitter, etc.). I read in the development section that turning flight mode on/off can help. Well for me, it sometimes helps, sometimes doesn't. I find myself rebooting to solve the problem at least. I am a little concerned since I might need my cell in case of an emergency and I definitely would not want to wait for a reboot to call 911.
The second one is about the GPS. If I open navigation and ask for turn-by-turn directions, almost every time, it gets stuck searching for GPS. The workaround for me is to launch Maps, wait a few minutes to locate my location; then ask for directions. Although, this might not work from time to time. Again, in the middle of nowhere, you are driving and need a quick and dirty turn-by-turn directions and your smart Vibrant makes you go thru a lot of hassle to accomplish your task.
Any advice from our community?
Thank you!
Flash to stock, call t mobile and tell them your gps is non functional even after the froyo update, and get an exchange. My gps works INSTANTLY. Cold. I type my destination in Navigation and when I press enter my navigation is already talking. No maps, no 10 minutes, no downloads, we all know these are often placebos and we are still waiting and waiting for a signal which can still go off road randomly, etc. none of that with a new phone.
I did not try the physical gps fix in the forums but that could work too. Your gps still not be fixed by software, its a hardware problem. It seems phones manufactured after October (?) do not have the gps issue. Worth the hassle for me, at no cost if you do it for the gps issues and there is no physical damage to your phone. Just make sure you flash back to stock before you call because they will ask you to go through your system information on the line. Back up EVERYTHING and put it on a computer, get your exchange and flash back to your favorite rom and enjoy your now fully functional Vibrant that works in every way you bought it to work. And make sure you not only factory reset before you send the old one in, but also delete anything incriminating on your internal sd because a factory reset won't do it.

Don't blame the rom...Your hardware sucks.
Been running TW roms since the Bionix 1.0 days and NEVER had any issues.
Those problems are not inherent to TW roms, it's a problem with the phone.
@TheSneakerWhore, @deadpass:
OK - it might the hardware, but how do you explain no dropping calls on stock 2.1? I've used on stock for at least couple months and never had to reboot my phone because it did not have signals (or had signals but no connection).
I also flash Axura roms and never have a similar issue but they are too customized for me.
PS: I am not trying to blame the TW roms specifically nor am I defending another rom. Actually, if you open the latest Development thread, you will see my post thanking those guys because of an excellent job they've done. I am just not happy with the data and GPS - which I never had an issue before starting flashing TW and thinking others might be experiencing the same.
Strangely my GPS and cell signals seem stronger on TW ROMs than most others... It might be just slightly different hardware (not all units are created 100% equal after all) reacting differently to the software?
Have you perhaps tried Trigger v1.5? I thought the theming was very tasteful, you may like it, and it seemed pretty solid on GPS and signals.
Thanks, @Oxirane. I will give it a try.
I would try out different modems. For instance jl5 and kb1 great with gps in my case. jfd, ji6, ka5-7 all were teh suck when it came to gps. It all depends on your phone and location too. So flash away and find whats right for you.

I lol'd @ this "I live in an area (Maine) where you never experience a dropped call since there aren't many people living."
I'm with the OP on the drop call and inconsistent data issue. By all means, I have flashed almost every ROM out there. Every single ROM on here is awesome and all respects to the devs. I'm currently on Bionix 1.2 now for the third time and what I have and still noticed is the inconsistent data drop 2-3 times a day. No biggie since I managed to turn airplane off and back on and everything's back to normal. At first I thought it was KB1 that's causing this so I decided to try out different modems/kernals. After playing around a bit, I decided to stay with KA6 for a few days and noticed data improvement but still inconsistent (loss data connection). I also flashed the ROMs (Axura and Einherjar) and I don't have the data loss. I also flashed all the way back to Nero 5 just to check it out. I do not have any data problems with Nero 5. Anyways, I don't really mind every now and then switching air plane mode off/on. However, the issue as mentioned by OP does exist on some phones.
I'm running Bionix V 1.2, and the last 4 ROM's before this were all also TW ROMs.
I have not experienced a single one of your issues. My phone is fast, smooth, and have excellent signal and data everywhere around my area.
I doubt it is the ROM, but I'm no expert and cant say that for a definite.
But if myself along as many others , including a few buddies of mine, don't see those issues it just seems unlikely to be the ROM.
But who knows....
Well im guessing its the change of modems that's causing your issues... im sure it has nothing to do with the rom espeically since you never had issues supposedly when using Axura (since axura is based on bionix). Almost all the roms on here are based on TW roms, just change modems, theme, add a few random options, from what i've seen in the code. Like other suggested tryin flashing different modems and find the one that works best for your area. I've been running Bionix V 1.2 since day one and have not experienced any of the issues you have describbed...

I know your not trying to act up or anything, but thats kind of just mean.
I mean these devs are helping us by giving us more options.
Most of them aren't based on TW.
some are, most aren't.
but your saying "almost all the rom on here are based on TW Roms, just change modems, theme, add a few random options"
I'd like to see YOU edit the modem and theme and add a few random options and make a ROM. go ahead.
I can say that TW is also just editing a few codes and theming on a ROM that Samsung made, and that they aren't developers.
TW set a standard, a precedent, and people will follow it, but they aren't copying it.
not complaining at all to any ROMs. just throwing out my input to let the OP knows that he's not alone in this world. To me, if there's a way around the problem, the problem is minor. Besides, I flashed and used different ROMs like changing diapers. LOL. I like to keep my Vibrant looked different every 2-3 wks. Pretty soon, we'll see a flow of new ROMs and I be all over every single one of them like "flies on sh!t". Dang, haven't used that expression in a long time. LOL

there is not "editing of modems" its changing modems... and theming is nothing more then changing pngs and .9s and edit xmls... its not very difficult... time consuming but not difficult. as far as what TW does to their roms in decompiling smalis and editing the Java, i've personally only seen a handful tru developers here actually doing it to what samsung has leaked. MOST of these so called roms have taken the edits that TW has done and just dropped their own changes on top of them. This has been proven time and time again! but regardless you are entitled to youre own opinions.
My point is that Axura IS based on TW's edit so if the issues persist in TW rom but not in Axura, one of the causes would most likely be due to the modem cuz im 99% sure that several Axura roms use different modems.... that is all i was trying to say.
One thing I have not seen in any of the posts that are having the issue is what modem you are using.
I will say it now, KB1 modem sucks monkey balls. I haven't had any dropped calls on it, but have stale connections all the time. What I mean by that is, my phone is sending data packets, but isn't receiving any for a good 30 seconds.
So, try a different modem. KA5 seems to be the best modem for signal and battery life.

THX Krylon360. To be perfectly honest, I tried different ROMs and modems and noticed some significant improvements. I totally agree that KA5 and KA6 are better for me in terms of signal hence KA6 is what I stick with as mentioned in my previous response.
surprisingly, these problems can come up from odd combos of apps or some configuration that is unique........ Lucky you
I had some phone disconnects on my phone when it was on a TW and Eugene kernel, but it was a custom mms I installed that caused the issue..... so you might look at what you got on your phone as well. Remember, some of the app developers did not or do not update their apps and this may cause an issue especially running a 2.2 platform (especially a ported 2.2 platform) if they are older apps. Food for thought
I was having the same issues with 1.2. dropped calls, no data, constantly switching from edge to 3g, etc. had no issues with nero. As everyone said, try a different modem. Worked for me.

Thanks everyone! krylon360, I should have mentioned the modem I've been using: KA5. So, it's weird how you and some others find KA5 and KA6 to work best and I had all these problems with it. Maybe it really is a unique combination of apps, configuration etc.
Last night I flashed KB1 and will give it a try for a few days. I tried GPS on my way to home; opened Navigation and entered directions, and I got instant lock. I see that as an improvement. Will follow closely. Thanks again!

There's nothing wrong with the roms i been flashing since i got my vibrant once flashing do you wait the initial 10 mins and then reboot before you start using your phone? if not you may want to try that. TW roms are pretty much flawless.

call log ( missed calls) not working after root.

I had recently had my phone flashed to the best carrier for the area im in ad noticed a few problems. im rooted with cm11 but sticking with the stock debloated rom. the carrier flash had actually cased some issues initially with the screen turning on and fully lighting up, but when i started flashing new roms that issue was fixed. I thought it had fixed all my issues, but as I found out yesterday, my call log is still completely null and void. it shows no calls in or out, and ive made plenty. but the bigger part is that I dont even know about a missed call until I get the voice mail notification. ive tried apps to record them but im guessing they work off whatever stock files control that and thy read nothing as well right now
has anyone had this problem or possibly know of a fix?
Me too!

I am also experiencing the exact same issue. Rooted Vzw g2 on page plus. I've searched phone for a log file that looks like it corresponds to the call logs but no love. It is a little obnoxious as I have no idea who calls me if I miss the call.
Have you found a solution?
me, too!
Any insight?
I've not found a thing that will help us, I've found others experiencing the problem, but no solution. I'm running a stock debloated rom and i think therein lies the problem. Something that was removed that was seen as bloatware is most likely what actually tracks the call log. I've been searching for a rooted bloated stock rom, but to no avail. I ran a few other roms and had a call log, but the roms overall sucked and i like the ui of the stock especially the camera app....I'll keep looking, but hopefully someone in the know sees this post and helps us out
I was flashing different stock roms and differet Gapps and whe it boots into the backup scree to set the phone up the number it was showing saying my sim was already set up wasnt actually my number. I dot know where or why the number was coming from. but alas, my call log worked ad on called id's it still showed up as the right number. so i began puttig all my stuff back on it and updating things and something i updated chaged that and now im back where I was without a call log.
i dont know what files i had flashed excatly, so now its just a guessing game and lots of flashing..
I am running through the same issue, no recent and missed call history, my messaging is fine. The G2 was rooted and flashed to PP. I am wondering if you have solved the problem, if so, could you please share your solution, very much appreciated.

I am having the same issue. I flashed to pageplus, rooted and installed xdabebbs rom. I dont see call history in my recent calls app. Please let me know of a solution
No solution yet, see someone say it could be because of flashing, so how you do the flash, yourself or someone help you.
Find out solution, simply reflash NAM only, i used DFS.
same problem here.
@gjbwj what for you mean reflash NAM?
Running VS982.5 ROM if it maters.
Pretty sure it was something I restored with TiBU that caused it. My wife's phone has the same ROM but I didn't restore anything but apps on her phone.
I would rather not have to start over for what should just be one file corrupted.

[Q] Phone reception/broadcast on CM and ASOP roms

I have tried many times now to use CM or ASOP roms and their like and I find that I consistently have the same problem: no phone calls in (I would boot the rom and then call my cell from my house), can't hang up after a phone call and lousy GPS.
I don't have these problems when using a stock (Touch Wiz) based ROM.
Why is this?
Clearly it's a software issue, what could possibly be missing in the various roms that would make this happen?

Has anyone experienced this problem and has suggestions as to how to fix it?
Thanks
I flash a LOT of roms. Sometimes two or three a day. (I am going to meetings but I will always be a flashaholic.) I am almost constantly on AOSP because I do not like how clunky TW feels and there are about three or four things an AOSP rom does easily that you cannot do easily or at all on TW. I have had all of the problems you mentioned at one time or another but never all at once. When I first bought my SG4 and started flashing roms the GPS was a big issue but that problem is pretty much nonexistent now. The same with the inability to make a call. I have not seen that in awhile. I recently flashed a rom that I thought was running perfectly until I made a phone call and could not get the phone to hang up. I had to reboot to get the phone to disconnect. That was the first and only rom I have had that problem with. I think I reinstalled it a few days later after it had been updated and it worked fine.
Other things I have noticed is that Google's voice recongition does not work as well on AOSP roms and there can sometimes be a problem with MMS.
I say all of this to say that first, these roms are in development. They are not perfect. They sometimes have problems. If a rom has a glitch you cannot live with, go to a different rom.
Next, you have to follow the installation instructions to the letter. If it says to stand on one foot while installing the rom do it. I have seen some roms that have really weird install instruction but if you do not do it, the rom is not going to work. Acheron's Super S4 has you use specific recoveries and reboot into recovery. That is a little odd.
Next, if you feel you are constantly having these problems with all AOSP roms, which is odd, try flashing a stable version. CM has milestones. I know Liquid Smooth has an official 3.1 that is supposed to be very stable. See if you have these problems are more stable versions and instead of nightlys.
Next, I have seen people on the exact same model phone and carrier have greatly different experience with a rom. Individual phones seems to have their own quirks you have to learn. I believe most of this type of issue though is user error and you just don't realize you are doing something wrong.
Finally, the one thing I know nothing about is unlocking your phone for the international version. I wonder if that has anything to do with your problems.
Good luck and don't give up!

Issues running CM13

So I got my S4 up and running on Ting and got CM13 running on it, was having the LTE issues and flashed the .zip for MVNO and got my lte working so that was fine. Everything was great but than I realized that when I'm at home (where I have very weak signal) that the network would drop out and it would just say no service and stay that way until I rebooted, than everything would be good again for a few minutes until it lost service again and it would not pick it back up. I flashed back to stock using odin and even though I would have very weak signal it would never fully drop the network and I could still receive calls. The phone is running on OK3, I tried the OCTOS CM13 rom and had the same problem. Haven't tried any AOSP or any other Touch wiz roms yet to see if the problem persists just because work hasn't afforded me the time to mess with it. I was curious if anyone else had these same issues though or if there was anything I could edit in the system files to get it to reconnect to the network after it drops it. I will note as well that when I'm at work where I have a strong cellular signal I don't have this problem at all, it's just when the network falls out it won't pick it back up again. I figure it has to be something simple that can be corrected but I don't have the experience or knowledge to even begin to know where to look and after almost a week of searching these forums and google I haven't been able to find an answer or a similar problem. Any help or guidance would be hugely appreciated.
Yes I feel your pain. I've been experiencing this issue also and have yet to find a fix. I did see that someone reported that they don't have the issue with the R1 build of OctOs. I have yet to test this but I hope it will fix the issue.

Well at least now I know I am not the only one! I'll keep searching for an answer and try a few other roms that aren't CM based and see if I can find some sort of solution that isn't running rooted stock firmware. Ideally something MM based. Also if you could link to the thread where someone else reported a similar problem that would be great. Let me know if you find a solution before I do, one has to exist I'm sure.
So I saw towards the end of the octos thread where other people have been reporting the same issue with CM13 and OCTOS, found the R1 version of octos, will give it a try and report back. Hopefully CM13 catches wind and can trace back to whatever it is that is causing this issue as well, I might try one of the newer CM13 nightlies and see if maybe the problem hasn't been remedied but I'm not holding my breath :-/ I just really want MM back.
So update, I installed the R1 version of octos and the "no network" issue has not reared its head again yet. I Flashed the buzzbeemvno fix as well afterwards and one thing I did notice, before the mvno flash I was getting 3g signal with the sprint profile, once I flashed over to the ting profile it was only pulling 1x as far as signal is concerned. I don't really mind though since I have a solid wifi signal at home and the main goal here was to just have reliable signal to receive calls and texts when I ought to.
Give this APN a shot. It's the one I'm using currently. I think I may need to make some adjustments still, but it seems to work well enough so far.
It's also usually a good idea to reboot into recovery and delete the telephony.db and telephony.db-journal files in /data/data/com.android.providers.telephony/databases/ after you have replaced the apns-conf.xml. The system will recreate those files on startup using the new data.
Blaises are you running that APN pack on the newer cm13 builds?
I'm running the APN I linked earlier rather than the MVNO fix., and I'm using it on OctOS R1 which is a CM13 build from March.
I'm using Ting on the Sprint network.
Can I get your opinion on oct-os? Is it a daily driver ROM? Did you guys stay on the ROM? Any advice for me or warnings?
Sent from my KIW-L24 using XDA-Developers mobile app
So I am on the older build of octos from the spring, it's been a great daily driver gives me almost no problems. There has been an occasional Bluetooth hiccup and camera hiccups. But maybe once a month, overall it's been a great ROM.

New ROM =New phone?

So I've had my OP6T for several months now and I've really enjoyed it and been impressed with it.
For the majority of the time I've used AEX as my custom rom. I always pick a rom with signature spoofing support so I can use microg. Also, my service provider is Verizon.
I finally decided after several months with AEX as my daily driver, I wanted a rom that is more up to date but I'm not really ready to update from 9 to 10. So I decided to flash The Skydragon rom. I flashed it super easy but could not make calls nor send texts. The entire time I used AEX, it made calls and sent SMS/MMS just fine. After I installed Skydragon I called Verizon and spent 2 hours on the phone with various tech specialists and in the end they said from their end everything looked like it should be working. They never got it making calls and sending/receiving texts.
It said out of service in the settings. I ended up switching back to AEX and as soon as I did, it began working properly again. I even tried to make calls and texts on my OP6T when it was 100% stock and it will not work
I wonder if it's because I was on AEX when I originally called Verizon last year and set it up? Am I correct in assuming that, each time I flash a different rom, my phone will appear to Verizon as a brand new phone? I couldn't get it to work on stock nor Skydragon but when I switch back to AEX it works as it's supposed to.

When you tried the other ROMs, were they unmodified?
OP6T works only with Verizon's LTE network, from what I saw online.
It may matter if your phone is international/unbranded, etc., and if the ROMs are for the appropriate version of phone.

My phone is international/unbranded. I'm not sure if the Roms were unmodified. I know AEX works and when I tried Skydragon I worked on it for close to 2 days trying to make it work. One of the options within the Skydragon settings was that I can choose the exact network to use. I chose LTE. After choosing LTE, in the settings it shows my phone number and my provider as Verizon but it says out of service under service state. The Verizon representatives told me on their end it shows that I am CDMAless and they did not have a solution.
I noticed in the Skydragon thread that some people were successful in getting their OP6T to work with Verizon but at least one other XDA member said he had no service.
Also, as I was in the process of switching back to AEX, I first went back to stock and booted up in stock and tried to make calls /send texts and it would not allow me to until I reflashed AEX.
What a nuisance. Since you're so familiar with flashing ROMs, maybe try some others, but I would first go back to stock again--completely back to stock, even if it means lowering your android version.
But follow the instructions very carefully--you may be in brick territory going back. I'd download the MSMTool just in case.
Good luck with whatever you do, if you don't stay on AEX.
