I have two VS980 phones that shipped to me stock with the 26a firmware. I have rooted both phones and have updated to the latest TWRP recovery. They both work as expected as long as leave them as they are. However, as soon as I install any custom ROM, they will both drop phones calls randomly.
I have tried almost every custom ROM available on this forum (Stock, CM, AOSP) and all of them will drop phones calls within a few minutes. I have also tried changing basebands and flashing my EFS backup without success. Data, Texting, Wifi, GPS everything works but no phone calls, even with full signal bars. As soon as I revert to stock, everything works like normal.
I have searched online and on the forums but I can't seem to find an answer to this. I am at a complete loss. I don't want to be stuck on the stock firmware forever. Does anyone have a suggestion?

I finally got superuser working by flashing Echoe Illusion, the full touch-wiz version with Android 4.3. At first it seemed like I had everything working but the next day when I left the house (no longer connected to home wifi) I quickly realized it was refusing to connect to mobile data. I also cannot send text messages, and likewise I can assume I can't get them either. I have tried flashing the nightly CM11 build and 3G connected although LTE did not. I wasn't in an area where I expected reliable LTE anyway so that's not even an issue at this point because I'd very much like to use this Echoe Illusion rom, or another Touch-wiz based one. I just can't go downloading a bunch of them because I have a severe restriction on data usage and have already downloaded Echoe Illusion AND multiple other things. If it matters, my baseband ends in MJA.
I have also attempted to flash different modems with Odin, although all of them failed completely to flash at all and at this point I have to honestly admit I don't know what I'm doing. This is most definitely not my first time rooting...I'm just used to HTC phones, the Evos in particular. Thanks in advance if anyone can help or provide useful tips!
oh and P.S. I can't go back to the stock firmware because I must have flashed an incorrect kernel, and it borked the phone. I only got it working again by flashing a separate rom (Echoe Illusion) and have since flashed other kernels with no ill effect. I had a nandroid backup of the stock rom before I borked it, but every time I try restoring it, it stops at the yellow Sprint screen and won't boot.
To preface the current issue with my phone, I guess I should probably give some history of what I've done to it. I got my S4 around November last year, where I kept TouchWiz for about a good 3 months. At the end of those 3 months, I downloaded and installed CM KitKat using their easy installer and it worked! However, when Lollipop came around, I got a little impatient and decided to get CM12 using Antares version. Initially, I noticed there were a few bugs/glitches, but ignored them for the time being. As time went on, it became increasingly aggravating and so a few dayus ago I tried to switch back to stock TouchWiz. When I was setting up the phone, I noticed that the wi-fi would just not turn it. It would stay at "turning on" for a very long time with no sucess. Thus, I decided to switch back to Antares version of CM, but now there were a few issues: service was VERY spotty and the piece de resistance: no sound at ALL, and youtube would never play videos. I searched around and saw that using the Sound Recorder would give me an error: "Internal Application Error. Microphone may be in use." Now I'm not the most techy person around and probably should not have been messing around with my phone, but now all I want is a properly working phone, doesn't matter if its kitkat or lollipop. Your help is greatly appreciated. (If you need to know more info, go ahead and ask, because I'm very new to all this) Thanks!
If you want the stock ROM back, flash it twice using Odin. General consensus here is that you need to flash the modem twice in order for WiFi and cellular radios to work properly. Flashing the ROM twice will do that without having to track down just the modem file and trying to flash that.

Unfortunately, it doesn't seem to be working :/ When setting up my S4, it's still stuck at turning on the wifi
I switched back to Antares CM, and everything works fine except for sound/microphone (to my knowledge). Would there be any way to fix this?
After upgrading to the Note 4 back in March, I recently decided to dabble in the rooting and custom ROM world of Android back in late June - early July.
I've been using CM12.1 nightlies since July 19th and currently have the August 20th nightly. One problem I had is that if I tried to update CM via the CM updater under the "About Phone" section, I end up getting "No Service" for my mobile signal/data which meant reflashing the stock firmware and reflashing TWRP/Cyanogenmod. So if I wanted to update nightlies (no plans to until Android M), I would have to manually get the nightly zip files from my laptop then wipe my previous nightly clean so the mobile signal would still work.
But the biggest problem I (still) have now is that I simply can't send text messages ranging from 10 minutes to several hours (Would just be stuck at "Sending..." and eventually "Not sent. Touch to try again") only after I turn off/restart my phone or turn on airplane mode. It shows that I still have connection to Sprint and I can actually use LTE/3g. Also interestingly enough, I can still call people AND receive their text messages, but I just can't send text messages.
It's not a big enough deal breaker for me where I would have to go back to stock ROM, but I'd like to know why this is the case. Since sending text messages seems to be the only problem, I assume it can't be the mobile signal itself since I'm still able to call, receive text messages, and use LTE/3g.
Things I've done/tried so far with no solutions:
1. Read older OPO/XDA threads about something called Voice+ causing the issue, but no such application exists on my CM.
2. Flashing the 5.1.1 firmware from Sammobile since CM12.1 is based off 5.1.1 Lollipop since I originally rooted and flashed CM12.1 with the 5.0.2 firmware. Problem still persists even on the 5.1.1 firmware
One final thing I will probably try to do is do an advanced wipe via TWRP, flash the stock 5.1.1 firmware and then get TWRP back via Odin and flash one nightly zip only and never attempt to update or flash new nightlies until Android M.
As for now, once I get my ability to text again, I'm not going to turn on airplane mode or turn off/restart my phone and leave it be. I have a fair enough standby time with CM (One night I only had a 2% drain in 7 hours of sleep or so without CM's battery saver mode) which is nice.
Any input would be greatly appreciated!
UPDATE: Apparently location seems to be the problem. I am now realizing that this issue only really occurred when I'm at my house. Even though I live in the city, it seems to prevent me from texting. But, I can text with no problems after turning airplane mode on and off or turning the phone off and on again at work and at certain stores I go to.

I am currently on the f model and after the N910FXXU1DPH2_N910FOXA1DPH2_DBT my phone has come to an almost unusable state. Fc, random reboots, freezes during calls, black screens etc. Full factory reset and reinstalling didn't helped. I have root and tried some custom roms but i need some opinions. I want a MM based rom with full Spen and snote usage. I dont care nor use fingerprint, shealth, svoice, knox, android pay, note 7 or edge gimmics or ports. I just want a stable light and reliable rom to fully use the spen, make and receive calls, send texts, use social media and have full data and wifi connectivity and as less bloat as possible. A theme feature will be nice but not mandatory. Cheers and ty in advance!
The feeling I get from reading the various threads on these fora is that stock ROM remains to be the most stable of the lot. If you are having these problems with clean stock then could it be your setup or a hardware fault that is causing these issues?
If it is not a hw issue, then it could be that TWRP has been corrupted. Try downloading and reinstalling your recovery.
I am using nameless now and it looks pretty sweet. About the recovery when I first updated it reverted to stock recovery. I reseted to factory settings which caused me to loss root. And today when I tried to get to nameless I could not get twrp to install via flash via odin. It succeeded but it always booted to stock recovery. I had to root first and then install twrp through it's app from the play store. Anyway all seems pretty solid in nameless I will try it out for a few days.
I had latest stock firmware and everything was working fine except it wasn't getting any updates so I decided to flash Linneage. I followed instructions, made sure to flash the copy-file on both slots etc. Everhything seemed fine untill I left my home and didn't have access to wifi, then I noticed that data didn't want to work. It showed having 4g connection (full strength) but it was so slow that I couldn't even check speed because the homepage barely load. There was a connection but since it was so slow I received timeouts almost everything I tried. I also noticed that bluetooth didn't work. It would connect/disconnect every 3 seconds from my bt headset. This was "fixed" by disable google on my phone. Very strange.
I thought It might have to do with Linneage so I tried Pixel experience. Exact same problem there.
I thought maybe the linneage files I flashed to both slots were bad so I reflashed stock rom. Now I have the same problem with stock rom as well. I eventually used the MSM tool and reflashed the latest stock firmware, locking the bootloader and all that. Still having the same problems. These two problems were non existant before any of this.
I've tried my sim in a different phone, even made sure the apns are the exact same on my working phone and my op6t.
Is there any other way to make sure the phone is completely factory restored other than MSM tool? Now I'm running stock oxygen, no root, locked bootloader etc but the problem persists. What is my next step to try?
