So my sprint s4 was on MK2, 4.3, so i used odin and found a MJA firmware on 4.3 and apparently it worked. After that my wifi was perfectly fine but then I rooted my phone and i cant seem to turn WiFi on so im stuck using 4g and also my PlayStore wont download anything

I've had my WiFi get stuck off as well, which required me to replace the ROM on the phone to resolve.
Anyhow, until you're ready to reformat your phone you could following steps in the link below to have your phone download apps from the store without wifi:

I had a similar problem. My Wifi would only work till I stopped using it (screen went off or I stopped pulling data). Then it would forget the local access points. I tried reflashing and changing my ROM. I formatted everything including the SD card. I finally fixed it by downgrading back to MDC and stock recovery. I took the MDL OTA (unrooted/stock recovery) and then flashed back to MF9 (manual not OTA) and then re-rooting it using ChainFire-Autoroot.
QBKing has a write up on how to do this for the MDL to MF9.
ChainFire-Auto root is posted in almost every other thread.
Doing it this method I did not have to format my Data partation and everything runs perfectly without having to freeze anything or such.
I upgraded to 4.3 and then i tried to flash a new rom which ended up messing my phone up badly. Luckily i had a back up but for some reason when i restore it it says all may apps stop working so then i have to do a factory reset. I do that and now my wifi will not turn on, my sound doesnt work properly, and neither does making phone calls. ive tried everything i know. i was also wonder if it was possible to downgrade from 4.3 to 4.2.
Which firmware were you on? MJA or MK2? If you were on MK2 try flashing the MK2 firmware off of sammobile thru Odin and see if that helps.. And no, you can not downgrade from 4.3 unfortunately...

Here is the whole story. I rooted. I get a custom recovery and flash cyanogenmod. Everything worked fine but it was pretty slow and I like the touchwiz interface so I flash GoldenEye rom. Wifi works flawlessly but 3g doesn't work at all. So I try to flash the 4.4.2 modem and flash official telus 4.4.2 kitkat. Wifi slider stuck on off and 3g not working. 4.2 Touchwiz works fine. 4.3 - 4.4.2 wifi and 3g not working. I did try flashing stuff with odin but still not working. How can I fix this problem once and for all?
OH please someone know the solution for this,
my story is near identical everything worked great in my Google edition Rom with older modem, I decided to update back to stock 4.4.2, and I can't get any mobile data. Now at first I couldn't get wifi either, I believe I manually flashed the NC1 modem, did a full wipeafter the install of stock, and it gave me back wifi. Alas still no mobile data, NONE.
I have tried re flashing the modem, I have tried re rooting... I am not sure if the re-rooting worked maybe that is our problem and then we need to flash the modem again, but I really don't know and I have been trying to fix this for about 8 hours now
My wallet will be 800 dollars lighter come Monday if I can't fix this, no smartphone is unfortunately no option for me.
Edit: So I downloaded superSU and rootchecker, all installed and verified fine, but superSU wanted to disable Knox.. so I let it, maybe that stopped a proper modem install?? (although I dont' see how I updated to stock 4.4.2 via kies)

Okay, I fixed mine the last problems were actually silly (apn setting was wrong isp.telus.com instead of sp.telus.com)
anyway
First I loaded up the original 4.2.2 firmware using odin 3.09 that gave me wifi back, I then updated to the newest software using kies 2.0 then I search in vain not realizing everything was working I just needed to enter my apn settings.
then I re-reooted, and installed the Maple Leaf rom because it is near stock with a few great additions!
Now everything works great, and the new modem easily gives me twice the bars in LTE as the old one did.

I am so stupid. Thank you so much. All I did was reset my apn settings and it was fixed.
I rooted to 4.4.2 and it went fine- then I realized I had lost wi-fi.
I have tried to restore and tried using odin and zip files to install a stock rom after I found a similar problem with link on
Sprint forums saying it will fix the ""button won't stay on" but the fix only works if the device is in stock rom.
answer on Sprint forum says baseband version was mk2 needs to be nae.
Return the phone to stock, run the fix for the wi-fi and then re-root.
I have downloaded and ran several roms that say they are stock- I've factory reset, cleared cache, no matter what I do,
I end up with a rooted device in 4.4.2 and no wi-fi. If I could just get the wi-fi back I would take it at this point
This was just a little quick upgrade that turned bad and long
The Sprint forum had a link to get it to nae, but wont work if rooted., so need to put the phone back to stock- run the patch and then can upgrade to kit kat again
TLDR: I cannot get my Sprint s4 back to any version that isn't rooted. I have tried several (lots) of roms that say" stock-unrooted" rom,
Never goes back to stock- stays rooted without wifi-
Ran a rom VPUAMDC_L720SPTAMDC_SPR but when I install I get msge "ifooter is wring signature invalid" - and it fails.
reformatted the sd card, tried different roms and get some message and it stays rooted and no wifi.
TLDR: need to get stock rom so I can get back wi-fi and then root the whole thing. as 4.4.2 Or 4 , if it exists)
Any options and any ideas as to where or what to do?
EDIT: for clarity cause I am not making much sense at this point
Thanks
Heh... a TL;DR for a TL;DR... the internet is becoming one crazy place.

Maybe a dumb question, but why not just unroot first, then?
Like many others I ran into a problem when rooting my i337. If you follow the popular instructions, you are told to install towelroot after loading the NC1 firmware. Like many, my wifi was disabled after loading NC1 leaving you stuck. On NC1 my PC would also not recognize the i337 as a drive so that wouldn't work either. Fortunately I noticed that Bluetooth was still functional and used it to download the towelroot apk from my bluetooth enabled pc.
I hope this helps someone else stuck in this position. I struggled for hours before noticing that bluetooth was working.
What instructions did you follow? They were probably for older firmware. Back then, You had to flash NC1 modules zip file after flashing any NC1 rom or your wifi wouldn't work. You still have to do it, but now you use OC3 modules.
