Hello everyone, i'm a new member. I apologize if my english is not good enough.
After been driven insane by one pre-installed app from my Operator (Claro Peru) i decided that it was time to root my device to get rid from that pest. I'm a noob, so i started to investigate about the safest methods to not damage my phone. My Device's model is SGH I337m.
The plan was to update the FW from JB 4.3 that came with my phone to 4.4.2 and then proceed to root. I downloaded the Canadian 4.4.2 FW with build version I337MVLUFNC1 and installed manually with Odin. After the phone rebooted, my S4 was upgraded with 4.4.2 but Samsumg keyboard was going insane, so i went to the apps and solved that cleaning the cache/data. Then i noticed that the Wifi wasn't connected, i tried to turn it on, but then a message with a shield appeared saying that my device security stopped the operation. Beliving it was only a problem with KNOX, i installed autoroot (CF-Auto-Root-jfltecan-jfltevl-sghi337m) with Odin, open SuperSU and stopped it from working, but the Wifi still wouldn't connect.
So the first thing that crossed my mind was to unroot and do a factory reset, didn't work. The FW still was 4.4.2, so i´ve been searching solutions with this FW because i've read some cases of devices that stopped working completely after trying to do a downgrade. so i don't want to go to that route for now.
After a couple hours of search, some solutions i found on the forum were:
- Install Faux123 Kernel (Found on Youtube, this would be the thread i think http://forum.xda-developers.com/showthread.php?t=2273437http://forum.xda-developers.com/showthread.php?t=2273437
- Flash a modem for i337m
- Safestrap recovery and bypasslkm.zip
- Downgrade
I haven't tried any of this methods because i dont want to get into a deeper trouble. In the first solution i'm not sure what to do because this is the files the author recommends for canadian models (i337m), but when i enter here http://faux.romhost.me/jflteatt/jb42/http://faux.romhost.me/jflteatt/jb42/ only jflteatt appears, and that would be i337 model, isn't it? I thought that installing it may cause more troubles, so i didn't do it.
For the flashing modem method, i'm not really sure if installing a modem from another country would get me in trouble, so again i didn't proceed.
I found the Safestrap and recovery method on a downgrade thread for the i337, so again, didn't do it.
So, is there a way to get one of this methods working on i337m to get wifi working again, or is there any other better method to get back wifi.
I would really appreciate any help you can give me guys.

ok so you have the i337m canadian version... making anything related to safestrap and the att i337 irrelevant, completely different methods so don't get them confused lol
you were updating from stock 4.3 right? your best bet is to factiry reset and reflash stock fw for 4.4.2 before you brick your device... kitkat is very different from 4.3, maybe read up on it a bit too...
for ex, the "message with a shield appeared saying that my device security stopped the operation" isn't related to needing to root, it's an option under security settings.
to enable superuser on kitkat you need to enable developer options, then enable superuser. I prefer supersu so manually install that from play store afterwards. I recommend checking and/or enabling this as soon as the phone completes booting up after flashing.
also I think there's a known issue w/ 4.4.2 and wifi not turning on until after 2nd boot completed if I rememebr correctly, been using 4.4.4 for awhile now though so could be wrong...
good luck and check out the help section :angel:
When I bought my phone I was on MF9 firmware stock. I rooted it , then tried to do the system hotspot mod. i ended up bricking the phone. The only way I could unbrick the phone at that time was to flash to MDC, which the hotspod mod was working on. Now ive been trying to flash newer custom roms,(because im still on ancient MDC), and I can never get it to work. Do I have to upgrade in order ? Ex. MDC to MDL to MF9 and so on ? Does my hotspot system file mods have something to do with it ? I really wannt try these new ROMS , but it just never works. Any help would be greatly appreciated.
I would like to know this as well. I'm stuck on MDC (i think thats the first firmware?) and I would like to know the best upgrade path in order to get the latest modem, ect.
I'm on mf9 with the hot spot working. Tried to go to the mdk modem and software, soft bricked twice. Gave up and went back to mf9. If it ain't broke, don't fix it lol.

Hello XDA,
I would just like you all to know that I am a amateur when It comes to rooting. So I was following this XDA post to turn my CDMA Sprint Galaxy S4 into a GSM. Galaxy S4 I followed all the directions but Odin failed for some reason and my phone tried to reboot. When it did that this screen came up. At this point I was pretty sure it got bricked, So I tried to fix it by looking up my error online. I downloaded some sketchy files and used Odin on the phone after putting it into downloading mode.
After all this the phone got unbricked, but when I turned it on my wifi wouldn't turn on no matter what I tried. I even downloaded a WifiManager App and put it on my phone. Even the app couldn't turn the wifi on. At this point I was freaking out so I restarted my phone a couple times and finally I factory reset it. Nothing has fixed the Wifi issue please help me restore my phone to the way it was before I did any of this. like with Stock Firmware and basically Stock everything. Please try to give me clear and step by step instructions because I'm very new to rooting.
Thank you!
Go to Sammobile, look up your device and download the stock firmware, and you should be good.

Can you please give me a step by step list to change the firmware? I'm a noob at this :crying:
So they other night i tried rooting my gs7 edge AT&T version.. Found a tutorial online and flashed a file via odin. And upon rebooting ended up freezing on the AT&T boot logo. which seemed to a common problem after reading the comments. The only way was to do a factory reset which i did and got the phone working again. But now the phone is extremely sluggish it lags doing the simplest tasks. Now i want to start over and flash the stock firmware via odin but not sure what files to flash something about pi2 and the BL. Can some one point out to me what is the latest firmware i should be installing. Just trying to go back to stock here.

You still have the eng kernel installed. Go to the AT&T forum for the S7 and you will see what others have done.
