[Solved] Missing Wifi on OD2, OH1, OK3 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I had been running CM12.1 for about six months now, but during that time I went from having 4G failing to switch to 3G and vice versa to 4G no longer working at all, and considering the CM13 unofficial rom floating around here I decided to give it a shot.
Before then, I wanted to do PRL / Profile update, so I flashed the beloated OD2 rom rather than downloading the 1.4GB official roms. Booted it, yada yada, 4g was working immediately but wifi would not turn on. Strange. I did my prl / profile update, rebooted, wiped system / data again, and installed CM13. Of course, cellular did not work at all, so I tried falling back to 12.1 again thinking a fresh install might restore cellular data. Wrong, this morning my CM12.1 install had working 3G, now nothing is working.
So I go and grab OK3 from sammobile since its the latest and flashing that does not work either. Recovery should have nothing to do with it, but I've been bouncing between latest TWRP and stock recovery from OK3, and of particular note all the stock recovery refuses to flash any stock roms, as does heimdall. Only way to flash any of these roms reliably is with TWRP at the moment.
So pretty much the issue is that cdma works on stock and wifi works on CM, but I kind of need both working on either rom to actually use my phone, and I'll take either at this point. I mean, why in the world does wifi work in Cyanogenmod but I cannot turn it on on any version of stock?
Unrelated, but I got this strange bug where the bootloader is insta-powering off the first time I do power + volup into recovery, so I have to hold the combo through two power cycles to actually get it to start recovery.
Update: I repeated the process and now have working wifi on OK3. So thats a thing. Now I'm just hoping CM13 will work with Freedompop one day so I can merge my data + sd card and finally install some apps on my phone.

[Q] GT-i9500 has no OS installed.

Hi everyone I just recently purchased a used S4 the GT-i9500. Everything seemed fine until I got home. It detected my T-Mobile Sim fine but I could only access 2G data and could not connect to any WiFi network I came across. The rom was stock 4.2.2 and the phone was rooted pre purchase. So after fiddling around for a few minutes I discovered the previous owner had flashed TWRP v2.4.1.0 as his choice for a Custom Recovery. Now at this point I had decided to flash on a Custom Rom and of course I first made a backup before flashing on WanamLite. Now after attempting to flash it I immediately received a failure. I tried turning off the signature verification and it did not flash. Now in my frustration i attempted to wipe everything and tried flashing Omega Rom v14. Now i was able to go through with the installation and choose what I wished to install and when I pressed Install things went along smoothly until I hit the app SecSafetyAssurance.apk where it freezes. This is a bump that I've run into at least 5 times already. I changed certain options I wanted to install and eventually made it past this and I am prompted to reboot. Now when I do this to my dismay I just receive a black screen. Upon pulling out the battery and attempting to reboot I still receive a black screen. when I boot back into the Recovery and attempt to reboot the system from within TWRP it warns me saying No OS Installed Are you sure you want to reboot. Im at a loss of what to do. I have read about other members suggesting to use ODIN but I am very confused about how to access Download Mode in order to flash a stock rom from SamMobile.com. I could use a few tips or maybe a few options that I'm left with in order to obtain the operation of my phone again. I would like to get my phone back and Im sure some users can relate to how Im feeling so any help at all would be greatly appreciated. Thank you very much in advanced!

Flashing through odin is one option.... some users have reported that there were some hiccups when installing omega 14 because of the aroma script.....try a different rom...there are many others to choose from....or you could flash stock via odin as said on the earlier comment good luck

Today I attempted to use ODIN to flash now I am still currently attempting this. When I press the volume down key, power, and home button it takes me to the custom recovery TWRP instead of download mode. The phone did this when I first purchased it. When I still had what appeared to be the stock rom it would always take me to the recovery. When I would use the volume up instead of down it would take me to the factory test mode now mind you this happened when the OS was still installed. When i try that combination now i just receive a blank black screen. Are there any other ways to boot into download mode?

[Q] Phone will not start after first restart from a fresh flash

I have scoured the internet to find someone with the same issue as me, and I haven't found enough to fix the issue, so I'm placing a plea for help here. I have installed TWRP 2.6 recovery, and I am trying to flash OmniRom 4.4.2 nightlies. Originially I was trying to flash cyanogenmod 11, but I had this same problem. It appears to be any kit kat rom that causes the problem (I haven't tried flashing stock or any non-kitkat roms, but I was running on rooted stock before I tried to flash CM11). Anyways, When I flash I am wiping dalvik, cached, system, and data. Then flashing the rom, then flashing Paranoid android gapps. It will boot the first time fine. My phone will work just fine afterwards. However, if my battery dies or I restart, I will be unable to boot back into the rom and my phone becomes a soft brick. It will just stay stuck at the galaxy s 4 logo for as long as I leave it on. I have left it on for more than 30 minutes and there are no changes. I can't have my phone being just a dead battery away from being bricked, so I am asking for your help! Anything is much appreciated!
One other side note: I had my phone just lock up on me once in the middle of it running just fine. Afterwards it turned off on its own and tried to restart, but it resulted in the same issue. I don't know if this is related or just a bug in the rom.

Omni clearly states that it is an alpha, so you mileage may vary considerably.
Sounds kernel related. Have you tried just reflashing the kernel and seeing if it'll boot after that. Or trying a different kernel?
Thanks for the reply! I actually just fixed the problem on my own. I used Odin to flash a newer version of TWRP and then flashed omni, and it looks like everything is working just fine. I read a few people saying that they were having issues flashing kit kat roms with older versions of recovery, so I figured it was worth a shot.

[Q] Ive created a monster!!!! I need help. LS980 no network.

Long story short (I can go into more detail if needed):
Had a stock rooted rom with a zv8 radio/modem on sprint. I successfully flashed the Optimus 2.2 rom with the new ZVA (Sprint Spark) modem and everything was fine and dandy and working perfectly for a few hours. Then i was a dummy and restored apps from my previous roms using mybackup and one of those apps was the xposed installer with a few different modules.
Phone froze, rebooted and would no longer attatch to a network. No signal, just a red x. No radios work, not even wifi or bluetooth. If the screen goes blank the phone will freeze and bootcycle. Or if it is on for more then a minute, it will freeze and turn off and get stuck in a bootloop.
Recovery worked. I tried everything. Flashing other roms, with the appropriate radios of course, and restoring my backup with the appropriate radio. Nothing works, and ive had the same issue with each and every rom and radio.
I finally whipped out lgflashtool and returned to stock unrooted to no avail. Same issue, except now my touchscreen is not responsive, which means no adb to reroot and the pc doesn't recognize the phone while booted. Now im aware of a method using Ubuntu to get a custom recovery on these when all else fails, but is it worth my time if there is no fixing my issue?
Also, how much can you do with the lgflashtool? Can i flash different radios or root using it?
Worst case scenario i will take my phone to sprint and get a warranty replacement. The only issue with that is, while the rootchecker in download mode shows "unrooted" , the boot animation on the stock .tot image is an lg one, not the Sprint logo one and i feel like the service person would catch on. Any idea on how to change that as well?
Thanks in advance guys! Im kind of freaking out that im running out of options.

I've done this. But I found one from a new source and I'll try it again. Would I need to flash the radio again? Thank Thank you for the help.

Phone not connecting data

Hey everyone, let me start off that I love XDA and I have been using this site for years! So let me give you a little history. I am still on 4.4.4. Recently I finally updated it to 5.0 and retained root, sweet! I also had a custom lollipop recovery that allowed me to go back to 4.4.x. However, I needed the wireless tether function and I could not find a way to get it unlocked without flashing some mod (which would brick my phone) so I used ODIN to flash back to a rootable tar image that I have always used. It was 4.4.2 on NI2 Kernal. Now normally, no matter how many times I ODIN'ed it, flashed it, restore a backup, everything would be up and running in no time. However, lately my phone has not been able to connect to the network completely for some reason. I can make/receive calls and texts. Anything using data though would not work. I called Verizon to see if they could reset something from the back end and they saw me and connected and running. Needless to say, their help ended almost immediately. I am currently running Ricks ROM v19.2 G900VVRU1ANI2 and was only able to connect to data one time a couple of days ago. I had to restart though and when it booted back up, it lost the data again. It does show that I am connected to 4G LTE, strong signal. I have tried the stock ROM 4.4.2, fresh install of Ricks ROM, restore my backup of Ricks Rom (maybe two weeks old), tried Eclipse ROM, nothing seems to be working. I've never submitted anything on here asking for help so this is a first for me cause normally I can fix any problems I create, however, I cannot figure this out for the life of me. Does anyone have any suggestions that I can try? Thanks in advance!

[HELP] I keep Loosing all Data on VS980 out of NO WHERE [please read]

I have a LG G2 Verizon Factory Unlocked VS980.... For service I have Straight Talk on a Verizon CDMA BYOD sim. It worked great stock. I never had a problem at all. 4G LTE all night and day, as soon as i put the sim in for the first time and turned it on the first time. Well i then used iroot, and AutoRec to flash TWRP. Stock it was on 24a 4.2.2. I like KitKat more then LP alot so I didnt really want to go to LP. I first Flashed a VS980 boot variant mod CM11 and it worked great. It kept my Data straight through the Flash. It held data for weeks no problem. Well at home I use WIFI and dont every try Data so one day I have no idea Data quit working until i went out, All mobile Data just quit working and i cant even use GPS, only calls and Text, no MMS either. I came home, searched up some APNs and edited it and it came back instantly. I thought that was pretty easy. Then I wanted to test the xdabbeb 2.3.0 because i liked the stock LG KK more then a CM Rom. Data again held through the Flash and for about the same time, 2 weeks, then suddenly one day i go out, goto pull up my broswer for internet and NO DATA. So I went home and couldnt edit a APN on this ROM, Every time i set it to the APN i found i hit SAVE and it just vanished, about 30 times i typed it in over and over. So I factory reset, didnt work, Flashed to 39A and tried LP Roms, Didnt work, Changed APNs on LP roms, Didnt work. Wiped it clean, flashed BACK to Stock 26a via KDZ, Didnt work. Changed APNs on stock, and wouldnt save again like before, It would save until i changed a certian field in the APN. So i went back to CM11 and set the APN, different APNs, Variations, still wouldnt work, So I went back to 28a Baseband, and flashed Xdabbebs KK rom again and again didnt work, but I loaded a Nandroid backup of that rom from the very first time i flashed it when it did work, and that brought my data back! So i sailed smooth on it for about about a week and BOOM, gone again!! I goto the Mobile Network settings and it shows 4G and 1X almost full signals, and LTE on the status bar still, when last time it didnt show LTE or the 4G's.
So, Im going to load this Nandroid again i suppose and see how it works, But what could be the problem? What is Changing settings wise or whatever and how? I am confused as hell on this! Can someone please help me out? I hate resetting my phone all the time, and dont want to make sure i have an OTG and my flash drive with me at all times and all my .apk's on my incase i need a weekly emergency Nandroid restore.
