[Q] my wifi not turning on. - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hello.
I have sgh-i337 with helf mf3 version.
My phone was rooted with mdl version
but my 5 years old son accidently did ota update
and some how it was not turning on
I did try to use kies to recover. Ofcourse
It crashed and not even boot on.
I did look the forum and got out from soft break.
but my wifi not working.
When I look on my system info.
buield number is mf3
but modem ver is mdl version.
I was try to reupdate thru ota
it can not. So I did try nf3 cfg file to update via odin.
md5 invailed. Is any way I could get cfg file with vaild

This has happened to me on several occasions, usually a quick reboot fixes the issue. But annoying, nonetheless. I've heard it's a kernel issue, I've tried everyone there is, and still get it occasionally.

This is strange. Sounds like your modem did not update, but that's technically possible to flash independently. It's just a matter of a risky procedure of using "dd" to overwrite your modem partition with the MF3 version. Also, if your modem partition didn't get updated, I'm wondering what else didn't?
I'm 80% certain that if your modem (and "NON-HLOS" modem) were updated to MF3, your WiFi would be fine.
I could provide the modem image file and a command to run from a rooted terminal/shell/ADB, but again, it's slightly risky.

You generally can't take an OTA update with root without fubaring something. Try to flash this file in odin v. 1.85 http://samsung-updates.com/device/?id=SPH-L720&details=Galaxy_S_4_Sprint
This is stock no root and SHOULD fix your problems.

oooooohhhhhh, ****... ok.... thank you.... i also realized i posted in the wrong section... i have a verizon not sprint
BTW, it didnt work =/
Same issue!
I'm currently having this same exact problem! I rooted my phone for the first time a few months back and all went very smoothly. I then tried to unroot it to install the update but ended up having to wipe my phone and I somehow deleted the update ZIP file. So I couldn't find any solution to my issue (although, I hadn't really looked into it as much as I'd have like to). But all failed and I ended up speaking with Samsung Tech Support at a Best Buy yesterday. They flashed the update onto my phone for me and all was well until I realized my wifi was no longer working. Whenever I try to push the wifi button it selects but automatically deselects right after. Even when I go into the settings, it's greyed out. I'm in the process of downloading the stock firmware and I am going to flash that and hopefully all will be solved. Will update when I see results!

Could anybody tell me how to fix my wifi ? i've been having the exact same problem. how to i do a complete reset/restore?? or is there a fix?

[Q] AT&T Unathuorized firmware.

Okay, so long story short AT&T has cockblocked me from recovering my phone. I know, it has a locked bootloader. I get that. But let me start from the beginning. I was rooted (4.3), and my phone auto updated to KK, and essentially soft-bricked my phone. Well, I had to flash my 4.3 firmware (or so I thought) back onto my phone through Odin. The firmware turned out to be 4.2.2, and all of it failed to flash except the modem. It still started up fine, but I couldn't connect to wifi. It wasn't even an option to turn it on. Turns out I was still on 4.3, with a baseband of MF3, and a build number ending in MK2. I didn't know how to fix this, so I've kinda flashed it with all sorts of things hoping it would help. I've tried all variations of 4.2.2 seeing if I can get things to be all either MF3 or MK2, so far no luck. Well today I tried to flash it with MK2 firmware, and it went like 95% through, and failed. Restarted, and it says "System software not authorized by AT&T has been found on your phone."
This is because of the bootloader, I get it.
The 4.2.2 modem is the only thing to successfully flash. Any clues why? Any clues onto how to recover my phone at all? You guys are true geniuses, please help.
Also, my device status is still on "custom" with the unlocked icon.
Any help would be tremendous, as I feel like a complete and utter moron. I have both Windows 7 & Linux Mint my use, so suggest anything. Please. I'm begging you.
I had the same problem i soft bricked my phone by installing MF3 and i was already on MK2. Just download MK2 http://forum.xda-developers.com/showthread.php?t=2621279 flash first only AP_I337UCUEMK2_1921628_REV06_user_low_ship_MULTI_CERT.tar.md5 by using PDA on oDin see if that fixes your problem.

Do you know of a good repository or place were i can download basebands updates (Modem.bin) for my i337?
If i upload a phone baseband i337 with a i337m, would it work?
Never mind found the solution in the forum. Thx

Question

So im gonna take the OTA for NG2 again and before I unroot and flash it this time isnt there a way I can pull the update from my files after i download it so people can use it to flash the update manually from their external sd card without waiting for the OTA?
There is a way to do so by allowing your phone to download the update file and then pull it from cache, but I'm not sure of the details.
@frostedunit Yeah I already did it lol and it works. But now my problem is I flashed it multiple times and it doesn't update my baseband or software to NG2 it only changes my build number. Also i cant turn on wifi.. it says "Your phones security has blocked an action that is not permitted. No further action is required"?
Good old Samsung trying to lock their **** down like Apple.
Don't suppose you could try to pull the modem files the way you did for NAE? I probably won't get the update till the last darn day.
That's only thing I really wanted to do was update to the latest modem lol. But I would need some directions on how to do it.
I opened up the update.zip file and found 2 files called
modem.bin.img.p
NON-HLOS.bin.img.p
I'm pretty sure you have to have the modem active, but see if this jogs your memory:
http://forum.xda-developers.com/showthread.php?p=50294725
OK I know how to do that but I still have the same NAE modem on my phone. After I took the NG2 OTA should my modem have updated to NG2 also or stay at NAE?
I would think so. If you saved the update from cache, you could try flashing it in recovery and then factory resetting to see if it sticks.
I tried that lol that's what worked for me on the NAE update to get the modem to flash but now I took the OTA and then manually flashed the update from my external sd card multiple times and keep getting the same results. I'll try a couple more times to see if it sticks.
If I can get the modem to flash correctly I can pull it by following the directions in the link that you posted.
Are you flashing with a custom recovery or stock? You should have to rename the file update.zip and put it on the root of your internal storage and use the stock recovery to get it to work.
(I'm just throwing things out there. I'm in no way implying that you don't know what you're doing, just trying to work through this.)
Yeah I forgot to change the name that might help lol and yeah I used stock recovery it actually updated my recovery on the first flash to NG2.
Still isn't working.. I'll keep trying but I'll probably end up waiting for the .tar file to be released. Either this update doesn't update the modem and software to say NG2 or the stock recovery is just having trouble flashing it.
Edit
There is an option in recovery to apply update from adb if I knew how to do that it would probably work.

I still think it's really crazy that this update blocks our phone from using wifi.. that's serious lol.

Probably some security crap with the mismatch between the build and baseband numbers.
Thanks for giving it a shot!
I updated through adb sideload and still no new modem lol.
Problem solved
I downgraded to MK2 modem and then reflashed NAE modem and took the update again from my external sd card and the NG2 modem stuck this time lol.
And it also fixed my wifi problem

can't boot phone

Hi, I started a thread needing help with my wifi but it has developed into not even being able to boot at all; it stops at the galaxy logo and either freezes or keeps booting. I have gone to the Odin page with all the different things to do and flashed the file to get back to the original rom but that is really where the trouble began. right now the only thing I can do with my phone is get into download mode, I can't even get into recovery. I have flashed a pit file that worked the first time but I don't know if that is part of the problem or not. Can someone please give me some directions, thanks
Also the phone won't boot at all unless hooked up to a power supply, the battery alone doesn't do anything.

More info is needed. What firmware / bootloader are you on? Was it rooted? Did you have a custom recovery installed? What version of ODIN are you using?

Right now, it sounds like you might need to use enewman17's ODIN debrick file.

It is the AT&T s4. To be honest I don't know what firmware I am on, it is the one the Odin page said to use if you want to go back to stock. I never rooted it. The bootloader would be whatever the latest update was for this phone. I can't get into it to tell you anymore. I am using ODIN 10, the latest one. thanks
Well I finally got into recovery and did a factory reset, now it boots into the AT&T white splash screen before it just turns off. I am also wondering if my battery just died for some reason?

ODIN 10? Try using ODIN 3.09 and see if that helps. The latest update would be Android 4.4.4 NJ4 firmware. This link should help you, it will give you root with safe strap recovery though: http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642
I meant 3.10, I will try the older version. What file should I flash?

Check out the link I posted in my last post. It should help you get your phone fixed.
I have been there. I went to the very last option which seems to be what I need unless I am missing something.
Neither odin 3.09 or 3.10 will even flash any file now. it either says invalid md5 or fails when it attempts it.
Well, I finally got it to boot into android but it is flaky at best. It is android 4.3 instead of 4.4 where it was initially. The wifi still doesn't work and now the keyboard keeps crashing everytime I do something. The build is jss15j1337ucuemk2 which I know is older than I had before. Does this give anyone a better idea of what I need to do? If I can get a stable flash then can I flash a modem file to fix the wifi? I really need some direction, thanks
Turns out the battery was completely drained which was causing some of the boot problems, I don't now how that happened but I am charging it now.
Well after using odin 3.8* I got it to install some older firmware ending in mk2 rather than the nc1 or nf4 that I had before the trouble. After I got it to boot, I went back into download mode and flashed the modem file and now everything works execpt I had to force stop Samsung keyboard and use swype. I would like to upgrade my firmware but since for a couple of more weeks it won't have a sim card I can't upgrade OTA. For some reason Kies says that firmware upgrade and initialization isn't supported with this model which makes no sense to me. It also says my firmware is up to date
Does anyone know how to flash to the latest firmware without me going through this nightmare again? thanks

If I were in your shoes I'd flash the nb1 tar file in Odin, any vein should work. See this for the tar file http://forum.xda-developers.com/showthread.php?p=56453100. You can then ota to the latest firmware which is 4.4.4, nj4

Download a firmaware for your region from sammobile and flash it via odin 3.10. It will solve most of your problems

I agree. But google has basically all he needs. More so rapidgator
I haven't found anything from Samsung to download. If I flash a newer build, do I also need to flash a modem file and a bootloader or can I just flash the PDA? thanks for explaining this to me.
And can I do a dirty flash so I don't have to lose everything again?
well, now I see that there is no sound. so I guess I will have to flash again.

There's. Something I'm yet to understand. Did you finally manage to boot into recovery? If so, flash a custom recovery (I recommend philz touch recovery) then use it to make complete wipe.
Then boot into download mode and flash latest pda firmware in the compressed file you downloaded. Ps: make sure it's from your region.
May be if you provided me with your region I'd get you all the files required

Help, tried updating baseband and ended up with no baseband at all

So after having some connectivity issues recently, I just tried to update the baseband on my I9505. I downloaded the newest version for my phone (XXHOJ2) and used Odin to flash it. The size of the file (1.5GB) indicated that I was flashing more than just the modem firmware, so I wasn't surprised to find myself back in a Touchwiz-environment after rebooting. I thought I'd just deal with it and re-flash CM12 after I was done (is this how it's supposed to work, isn't there a way to update the baseband without flashing a complete stock ROM?).
Anyways, now it seems my phone simply doesn't have a baseband. It says "unknown" under "Baseband" in the settings, and it won't recognize the SIM card or even turn on Wifi. What did I do wrong?
And more importantly, how do I fix this?
To flash just the modem, you'd need to extract it from the tar md5 package that the ROM is packed up in. Then you can flash just that part through Odin.
To resolve your problem, flash the ROM again. For some reason, Odin installs of ROMs don't always function 100% properly when done. Usually, flashing the ROM again resolves the issue.

Yeah, I realized that just now. I didn't even bother to look into the .md5 file before... Anyways, I tried reflashing with Odin and I got the exact same results. Baseband unknown, IMEI= null and no sim detected.
EDIT: Wow, I don't believe this... In a last attempt to save my phone, I just rooted and installed TWRP, then flashed an old nightly of CM12 I still had on my external SD. Didn't expect anything to happen, but voilĂ ... IMEI is back, Wifi connects, sim is detected, and baseband now reads XXUHOJ2, which is what I was initially trying to update it to. No idea how exactly that fixed it, but I'm sure glad it did!
I know you were using Cyanogenmod, but try installing the stock ROM on your device prior to installing Cyanogenmod and see if that restores your IMEI and baseband.
