This is my friends s4 he gave me to fix, its never been rooted or anything but after installing the 4.3 update the phone never had service and always has the "preparing network" thing in the notification menu, and if you go into certain things such as the about phone settings it will just freeze. ive tried factory restoring it but nothing has worked. Maybe downgrading to 4.2.2 would work but is that possible atm?
You won't be able to downgrade it to 4.2.2 after going to 4.3. 4.3 is different that way.
If the phone was never rooted, I'd say take it back to Sprint and let them fix it.

Which baseband are you on now? MF3? MJ6? Before which baseband were you on MDL? or MF3? What root method did you use?
It sounds like you rooted your phone, but did not take measures to prevent over the air (OTA) updating.
That OTA updating will destroy root, and lately also locks your bootloader in a manner that is even more restrictive.
It does not sound like you used any custom rom, and did not use Safe Strap either, but you need to provide more info for folks to work with.

You need to read all threads about 4.3, MJ6, and MJ9 in the "General" and " Q & A" sections of the forum to learn about what is happening with your phone.
Galaxy S4 - i337m - Android 4.3
Okay, so here's my problem.
Today in the morning after I woke up, I checked my phone and it said it had downloaded a software update. It was just a complimentary update for 4.3, it said bug fixing, etc. in details. I clicked accept and the installation started.
After this, all crap started to happen.
The Wi-Fi NEVER worked again, everytime I clicked the Wi-Fi widget in the notification bar, it turned green and immediately switched back to gray. It also didn't work when trying to turn Wi-FI on from the settings menu.
I tried everything, the battery pulling, the thing of disabling the Wi-Fi energy save, and nothing worked. It all pointed to a factory reset.
So I did all my backups (My S4 was rooted), and finally made the factory reset.
After this finished, I did all the starting configuration of the S4 (like when it was brand-new). Then, I tried to turn on Wi-Fi.
Surprise, surprise. DIDN'T WORK.
I'm so desperate right now, I don't know what to do.
I'm currently downloading 4.4.2 to flash it via Odin, and see if this works.
Any help, please?
Flashing the 4.4.2 ROM you're downloading now should definitely fix the problem. I know that in some instances, us I9505 owners have to flash a stock ROM twice through Odin before the modem will function. It sounds like your software update broke the modem in this fashion, which is why the ROM install you're planning should fix it. Be aware however that installing KitKat will give you Knox if you don't already have it.

Fine. Right at this moment I'm installing 4.4.2
Hope this works.
I'll tell you what happens.
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?
For a few weeks now, I have been unable to update my galaxy s5 to lollipop 5.0. I the download the update perfectly fine, but when I go to install it, it loads for a minute then says error. Now my phone was rooted, but one day it became unrooted. I tried to reroot it but it didn't work at all. I have a feeling when it unrooted, it didn't fully unroot? So I may have done something wrong here.. if anyone has similar issues and knows what may be wrong can you please help me!! I have reset my phone many times and nothing works!!
I have tried everything I can possibly think of in a short period of time, and need an answer in a hurry. The phone (Verizon Samsung Galaxy Note 3 N-900V) was rooted back when kitkat was the main OS using geohot's towelroot (or possibly kingo root I can't remember which i used after I got the phone and upgraded from ICS). I have 2 of these exact same phones, used the exact same rooting method, and unrooted by uninstalling the superuser app, rebooted, and installed the OTA update to lolipop. My phone works fine, (the one I'm typing from) however, my other phone decided to take a dump. It's a software bug between the samsung firmware and the new lolipop OS. It was working for several months, then all the sudden it wouldn't recognize/register the APN. Now it doesn't see anything just about with the phone. Not even the IMEI from the phones serial number. The sim card has been replaced twice and has worked for a matter of a few hours, however, upon restarting the phone, it goes back to no service, and nothing is registered or recognized. I reflashed the phone with the stock 5.0 Lolipop using Odin several times to no avail. My phone (one I'm using now) once did this months ago, and I was able to access the service menu and reregister the SIM card and phone has worked fine since. With this other phone, I can't get into the service menu at all because nothing is registering. So, after reflashing 4 or 5 times, factory reseting from both the OS and from recovery booting, it still has the same issue. Here is my question. It used to be when I reflashed, the custom padlock would disappear. I'm getting a new phone tomorrow, and I need to get rid of the custom padlock before I return the old phone. I can use Odin, or whatever but it has to be something, I can do while it stays stock. The knox counter has not been tripped, and the flash counter is not tripped nor showing anything on the download mode. Everything lools, and feels stock, except that custom padlock. Is there a way to get rid of that custom padlock unrooted, by reflashing? I even used a pit file to repartition, but that didn't work either. Need help A.S.A.P.!
I would just hard brick the phone just before returning it...they will just throw it out at that point and your secret will be safe.

You thinking maybe a NAND erase?

I've thought about flashing the wrong rom too but dunno if that will work 100%. I either need to fix it, or make it 100% unrecoverable. Any advice?
