[Q] Wifi lost; Unique problem maybe.

Anyways as my title says, i don't have wifi. I had first rooted my phone, but then I unrooted my phone by flashing some unrooted os on the samsung which caused two problems. My wifi and mobile data didn't work at all, but after I took it to a repair shop they fixed the mobile data and got it working again and rooted my phone but not the wifi part. According to the person that tried to fix my phone, the current android os, 4.3 - jellybean, that i flashed via odin is preventing the wifi from working. I don't really know whats wrong with the phone but can anyone help me? Also by baseband version is 1337UCUFNJ4 and the build number is JSS15.1337UCUEMK2. Should i try to find a ROM that matches my baseband version and flash it via odin? Thank you in advance!
P.S. This is my first thread, so please tell me if i violated any rules.

im having the same problem and i think we both have knox stupid security back on the phone that's blocking the wlan to start from bad permission or encryption
so personally yeah i will install back the original firmware (before 4.3) from factory reset (or via odin if i have to force it) then im gonna re-root the phone
having back permission ill remove knox (probly with titanium) lock and box bs from base firmware and probly remove root right
then im guessing ill have my internet back now will i go full rom again or basic function thats a good question
so many freaking remote exploit lately
ill let you know if that fix it

I also just found this

1. untick "Auto reboot" in odin
2. flash the stock rom again
3. reboot your phone to download mode again (by holding the power and vol down button for 10 sec)
4. flash the stock rom a second time with auto reboot ticked
This will fix your problem.

seems that clicking auto reboot might be the cause

so would i install the I337_NJ4_Stock_Kernel.tar.md5 file following that method or would i have to find another firmware/rom/(i don't know what to call this) unrooted

so if you dont mind the 9505 change (more rom and solution for 9505) id go with echoes for all in 1 fresh install solution and its a nice rom
Instruction can be found on this thread : http://forum.xda-developers.com/showthread.php?t=2372286
knowing the problem was modem i did also found this solution to re-flash and fix wifi on i337 without changing to 9505
Follow these instruction to stay i337 : http://forum.xda-developers.com/showpost.php?p=46762296&postcount=1
but i have not tested for i337
in the end i got this setup

Rogers Canada: i9505 "App stopped working" and cellular data not working off and on

Rogers Canada: i9505 "App stopped working" and cellular data not working off and on
Hi, I have the galaxy s4 i9505 from canada on rogers network. The actual model is SGH-i337M though. I have been using cyanogenmod but most recently, the optimized cyanogenmod 5.1.1 from alcurd. And for both OS's I have constant random app crashes from gapps and stock cyanogenmod apps. they randomly crash when i'm in them or they'll crash right away when i try to open one. they don't always crash, but it happens enough to get annoyed from it. Also my data disconnects all the time. it will say I have no service. this happens everynow and then. I've tried installing stock samsung firmware for 5.0.1 then installing cyanogenmod optimized after but it does nothing to fix it. I've even tried installing the new modem after. maybe I didn't find the right one, i'm not sure. Does anyone know what could be causing these issues and help me out with how to fix them or does anyone know a good rom that wont have these issues? I want a cyanogen like rom or pure android. I hate samsungs stuff lol. Thank you so much if you can help :]

Then you don't have an I9505.
I don't think there is a separate modem file available for your S4, unless it's in the forum for your device, so you'll likely have to download the complete ROM. The correct ROM for your S4 is here. Make a nandroid backup of your current ROM and make sure it's saved to the MicroSD card. Flash this ROM through Odin, let it boot, and let it take care of its business. Then head back into download mode, flash your custom recovery, reboot into the recovery, and restore your nandroid backup.
I would try and find just the modem and bootloader package for your S4, as none of the modem/bootloader packages here are for your device. If you can find that, then you can avoid having to do all the steps above and simply flash the modem and bootloader via Odin.
With luck, installing the right bootloader and modem will cure many of your issues.

Would it be this: http://forum.xda-developers.com/galaxy-s4-att/general/sgh-i337m-canadian-stock-official-t3082758 ?
It only has modem file, theirs no bootloader :/

It's marked "Modem/Baseband" so the one file should cover both. But even without the bootloader the modem should still be able to be flashed.

No cellular network after installing CM12.1 on Straight Talk SM-G900F (klte)

I recently installed TWRP and then the latest snapshot of CM12.1 for my phone described in title. The android version was upgraded from KitKat (4.4 I believe) to 5.1.1. Everything works fine with the install except I have no network whatsoever. Can't text, can't call, can't use data etc. I made a post on the CM subreddit but didnt get a lot of help (can't post link) . Here is what I have tried: changing APN settings (which I have heard should at least let me call and text if incorrect); flashing various modems such as BOE3, BNL9, and BOD3 (all of them get a FAIL! (auth) in ODIN); restoring my KitKat backup (makes the phone unusable); trying to flash the default L rom for the phone (Also fail to flash in ODIN and TWRP). So at the current time I am basically stuck on CM12.1 and all of its amazingness with no phone functions, I basically have a small tablet at the moment lol.
Here is some information from the about of my phone, if it is helpful at all.
Model: SM-G900F
CM Version: 12.1-20151204-NIGHTLY-ktle (Installed the nightly after the snapshot didn't work, same problem persists)
Android version: 5.1.1
Baseband version: S902LUDU3AOG2
Carrier: Straight Talk
If any more info is needed, just let me know. I appreciate any help, as I am pretty much at square one still. I have googled for days to try to fix this, and haven't come up with anything. It seems no one has had this specific problem before.
If I can't fix this issue, is there any way I can downgrade back to what I had to begin with?

I only have one other sim card on me, and its through verizon. It didn't work on the phone either. I would definitely just buy a new sim card if that would mean it would work. The whole IMEI thing worked, but I am not sure what to do with that information.

(Definitely a G900F? Check what it says in download mode)
Checking the IMEI was to make sure you haven't wiped/corrupted the EFS partition, which contains the Radios needed to make and receive called, along with the IMEI (Hopefully you researched enough to back that up before messing with the phone)
Try flashing another stock ROM with ODIN 3.10.7, go for a different Lollipop ROM from sammobile. com
Some stock ROMs fail to flash, some work, (Phone dependant it seems)
Then boot into recovery and factory reset > try to boot

I have tried 2 separate L roms for the G900F. It says in download mode the phone is a SM-S902L and I read somewhere to get the true model of the phone you look at the FCC id under the battery. Well the FCC id says it is a G900V. at one point in trying to fix it, I tried a stock L rom for the G900V and TWRP told me that it was intended for a kltevzw device and that mine is a klte, so that is why I assume that it is in fact a G900F. I have been using ODIN 3.10.7 to flash everything as well. (Have't tried TWRP for the most recent tries since it takes longer to setup and I doubt it would work but it's worth a try I suppose.
I looked on Sam Mobile for the SM-S902L and there is only one firmware for it, which is 4.4.2, the same one it was installed with when I got it. From my understanding SM-902L is the straight talk branding of the G900V, and trying to flash that firmware didn't work either. Every time I try to flash something it terminates with a FAIL! (auth). What I also understand is that Straight Talk has not released an official version of L for the phone. So it seems my options now are to somehow get the modem to work right in CM12, try to somehow downgrade to 4.4.2, or wait for Straight Talk to release an update for my phone which is not really an option. I just got this phone and I really don't want to have to buy a whole new one just because of software problems. In my mind there HAS to be some way to fix this.
EDIT: my bad, I should have mentioned when I tried to flash the G900V rom it was also CM12, not a stock.
EDIT AGAIN: I seem to have fixed this problem. I have no idea how I did it, but I finally got it to restore to the stock 4.4.2 rom. I seriously have no clue how it worked but it did. Texting and data once again work, but i am now having a problem where I can't make or receive calls. Call immediately ends/goes straight to voicemail. I don't suppose you know anything about that, if you do that would be awesome. I'm gonna call ST in the morning and see if they can tell me anything from their end. But otherwise, I guess my problem is solved. Lol.

I know it sounds simple or may sound stupid but have you tried entering your APN? I have to do that with most of the custom Roms I flash or I won't have service. Also, make sure the correct modem is flashed and up to date.

Help need please

Hi.. I have recently rooted my Samsung galaxy note 4 SM-N910F and I am wanting to downgrade from marshmallow 6.0.1 to Lollipop 5.1.1. I really need a dummy guide as I don't know how to do it and help will bbe appreciated

Hey there. Downgrading to an older version of Android means you'll have to factory wipe, but other than that it's pretty straightforward. Seeing as you have already rooted your phone, I assume you know how to use Odin, but here's all the steps anyway:
1. Download Odin
2. Find a Lollipop firmware for your device from SamMobile
3. Back up important data, and factory reset. You can do this in settings or in recovery.
4. Turn off your device, then hold power + vol down + home to put it in download mode
5. Open Odin, and put the firmware file you downloaded in the AP slot
6. Plug your phone in. If it isn't recognized, you probably don't have all the drivers installed - the easiest way to get those is to install Kies or SmartSwitch from Samsung.
7. Click Flash, and wait until it's done. Do not unplug the cable under any circumstance!
You're done!

Did you ask/search in the rom thread?
Maybe someone else had the same problem.
It could be a kernel issue, try other kernel.
I don't use a G but a C version, so I can't test to see.
Also consider the eMMC issue of the 910 SnapDragon, search about this.

Thanks for reply dear
Can i update or change kernel ?right now im on H-vitamin any other kernel can you suggest me is better then H-vitamin?thank for your support

Roms Not Working!

I'm trying to flash roms on my N9005 but I'm not able to succeed.
I tried first flashing the Fougat rom, I got stuck at Galaxy note 3 bootloop
I tried the Lineage 15 rom. It required TWRP v3.2.1, tried flashing it, but it didn't load
Tried flashing MagMa NXTeam's rom, same with fougat.
Im sure %100 I followed devs steps to flash but nothing is working for me!
Help devs, please!!

Did you confirm the model # in download mode?
Did you try flashing other ROMs that work with an older version of TWRP?
The phone is running the latest bootloader and modem?

1 Its not a N9005 or a fake .
2 User flashing stuff not for a N9005 .
3 Possible damage to a partition .
Judged by previous multiple users posts its likely partition damage .
https://forum.xda-developers.com/search.php?searchid=446754566

same for me since i change complete screen LCD+tactil.
Original rom work great but no custom rom. I bought complete screen on china ebay store.
Is screen version is really same that mine ? how to verify ?

I've read through a couple of your posts you've made on several ROMs and even TWRP, it sounds like you are flashing the wrong version for your phone. In several instances you've asked whether to install hlte, in the TWRP thread it seems like you're just letting the phone reboot (which re-installs stock recovery). You might either want to research more into what you are doing before you brick/damage your phone or leave your phone on stock.
