Rooted and Unlocked [att to tmobile] Nothing working!

Hi! I am having major issues with my s4 i337 after switching from att to tmobile. The phone was unlocked so I took it upon myself to unlock it. It is unlocked but sometimes or rather most of the time does not pick up the network. When it does have data connection, it is Edge. I flashed the NC1 to root my phone, then reflashed to NJ4 (to unlock) but now nothing works. No wifi, camera fails, no multitasker, no voice assistant. Please help!!!!! I don't know what to do. I should have never unrooted it to unlock. I should have paid the $35 to get an unlock code. Can I fix this?
I have tried multiple APN settings,
Tried reflashing what I found online as att official firmware but it fails on ODIN.
So reflashed to NJ4, it is a bit laggy as well. Tried wifi which is greyed out, Camera still shows failed, pressing the home button to open multitasker and voice assistant brings up a blank grey screen. Phone is no longer connected as a mass storage device, only charges and can connect to ODIN.
I have attempted to factory reset which doesn't go through, unroot through SU which gets stuck on uninstalling and even trying to do an emergency recovery on Kies where it fails and gets stuck on kies failure mode.
I am on 4.4.4

I'm not sure what you mean by re flash to nj4, but have you flashed the nb1 tar? http://forum.xda-developers.com/showthread.php?p=50912149

No I have not tried that one! Should I try it and which version should I use since I am rooted?

I guess I was following outdated information for rooting. =[ Which was dated 2013.... Should have sensed something was wrong.
I flashed this and it worked perfectly as you suggested! THANK YOU SO MUCH. No more sleepless nights combing through forums, thanks to you! Everything works and is back to normal, I was about to just throw away this phone thinking I permanently broke it. AGAIN MANY THANKS! I'm scared to root it now.
Although I have one more question, if you could please answer.
After booting and everything working, in the notification, it says unauthorized access and to restart to reset changes made, if I dismiss it, will this fix be permanent and not revert to the unworkable state it was in? When I reboot manually?

It doesn't really matter since you can root the device in either case. The rootable nb1 can be directly rooted. The other one, you'll have to update to nc1 to root. Flashing with odin, you will lose and will have to re-root. Also, see "Index All things AT&T...." by Gutt13 in the General Forum

ODINing to NB1 should definitely help, but as far as mobile data if it still isn't working I thought i read somewhere that T-Mobile needs the AWS bands or something and you'll have to follow the process to enable those. There's a thread somewhere in the General section to do it on 4.4

Pattern lock after flashing new rom

So I recently decided to flash back to stock. I did so via Odin and the firmware of Sammobile. Everything worked until I booted my phone up and it asked me for a pattern, which I never set. I tried different stock firmwares and always had the same issue. Since I still have a nandroid backup of my stock firmware I decided to restore that, again with the same issue.
Since the patterns background is all grey, I believe it has something to do with encrypting the phone, because it is not showing the usual Samsung pattern. I did encrypt the device a couple month ago but went back to a non-encrypted phone soon after.
I couln't find a thread or anything else online so I decided to post here.

Hi ^_^
1 ) Could you tell me the steps of Using Reset !?
2 ) what kind of Encryption you used to do with your phone ?

Hi ^_^
1 ) Could you tell me the steps of Using Reset !?
2 ) what kind of Encryption you used to do with your phone ?

Well first I followed the Sammobile instructions:
Extract (unzip) the firmware file
Download Odin v3.10.7
Extract Odin ZIP file
Open Odin v3.10.7
Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait few minutes

The encryption I used was included in CM12.1. But I wasn't happy with it and there was no way to remove it within CM12.1 so I formatted my data und basically reinstalled everything. Maybe this didn't get rid of the encryption all the way?

I just used the stock recovery and did a factory/data reset and it finally worked! I don't know why it didn't work when I wiped with TWRP but I got it now. Thanks anyways eaglef19.

Samsung Galaxy Note 4 SM-N910W8 (Canadian) Hard-Bricked; Any Solutions?

I have a hard-bricked Samsung galaxy note 4.
After I rooted my note 4, it started to display problems. It would randomly crash processes, reset, and freeze. One day, it turned off by itself despite the battery being at around 40%. I tried to turn it on but it wouldn't respond.
I replaced the battery thinking it was a battery problem. It didn't fix the problem. I also replaced the power button inside my phone. That didn't fix it, either.
My phone cannot enter download mode. It also doesn't respond when i plug it into an outlet.
When i connect the phone to my computer, my phone is recognized as this device:
Qualcomm HS-USB QDLoader 9008 (COM5) [Ports(COM&LPT)]
Manufacturer: Unavailable
Model: QHSUSB__BULK
Model Number: Unavailable
Categories: Unknown
Description: Unavailable
Does anyone have a solution/fix for de-bricking a hard bricked note 4 SM-N910W8 with these problems? I've searched everywhere w/ no success. Thanks.
Edit - GREAT NEWS, fellow N910W8 users! A user posted the N910W8 debrick image, today! I haven't used it to debrick my phone, yet (My phone is disassembled and i may need a new battery) but there's no harm in trying it.

Please explain what exactly did you do before starting to have those issues. What did you use for rooting?

Ok. I'll explain step-by-step. Since i'm a new user, i can't post outside links in my messages. I'll try to explain how i did it w/o links. I'll PM you the links i used to give you a clearer message on how i did it. Hopefully, i can PM links.
1. My phone was initially running 5.1.1 lollipop (n910w8vlu1coi4) before I decided to root it. It didn't display any of the problems that it had after rooting it.
Unfortunately, i used a guide that doesn't seem to exist, anymore.
I downloaded these files
- CF-Auto-Root-tritecan-tritecan-smn910w8.tar
- SuperSU - v2.65-20151226141550
- Odin3 - v3.10.6
- twrp-3.0.2-0-tritecan.img.tar
I did all of the pre-req things i was supposed to do before rooting (turned on developer mode & turned on USB Debugging). I put the CF-Auto-Root file in the AP field of Odin & pressed start. It passed. Afterwards, i put my phone in DL mode again and installed TWRP via the AP section of Odin. It passed as well.
My phone didn't root initially from doing both of those things. I had to go into TWRP and root the phone from there.
2. After doing all of that, my phone started to crash processes. Contacts crashed first from what I can remember. Others crashed over and over again. I thought it was due to having a bunch of apps on my phone prior to rooting it that didn't react well to the custom firmware/root. I decided to factory reset the phone via the OS' settings. When it turned back on, it continued to crash processes.
3. I decided to install CM 12.1 to see if that'd make a difference. I installed it via TWRP.
When i first booted CM12.1 up, i found that processes didn't crash on it, anymore. Also, it was faster than it was before. Unfortunately, it started to display other problems. It would freeze, reset, and turn off on its own. I reverted back to what i had before when that happened.
4. I decided that the CF-Root Tar image i installed to Odin to root my phone was screwing it up. I decided to un-root my phone by going back to stock firmware. I used samfirm (Samsung Firmware Downloader) to download the latest stock firmware for my phone.
Android 6.0.1 was the only stock firmware i could download. This was the name of the file:
SM-N910W8_1_20160507131653_k12ydzqths.zip
I flashed it to my device via odin by putting it in the AP section of the program. It passed.
5. When i booted up my phone after that, it seemed fine. It had a battery drain problem but that was a widely reported problem w/ android 6.0.1. My phone also wasn't rooted, anymore.
Unfortunately, the problems my phone had before came back. It would freeze and reset here and there. The processes didn't crash like they did after i initially rooted the device, though.
6. About a week later, my phone turned off by itself & wouldn't turn on anymore. I hooked up the phone to my computer and it wouldn't recognize it as a note 4. It recognized my phone as "QHSUSB_BULK".

You should restore it w/ odin. Type in "Galaxy Note 4 restore odin xda" on google and you'll find a few good threads.

Nope. Not yet. I've been searching and searching for months and haven't found anything.

Same here. I've been searching everywhere for a 910W8 debrick image everywhere but no luck. If anyone has one, please post.

getting an error after factory resetting my phone, failed to mount/preload....

Ever since I've been having problems with my phone, I've had to constantly factory reset my phone from recovery. It always had an error (failed to mount/preload......) but never thunk anything of it, because it rebooted fine, but eventually these very same problems keep arising. I am wondering if its this very error that makes phone have problems. Any ideas? I'm non root, and never attempted to root. Is it possible to fix my phone? Or should I speak to samsung for an replacement? Thanks guys and girls.

Just Odin. It won't mess with anything other than erase everything and start you from scratch with the latest build. Best option I'd say

You did not say if you are 935T. If so, you could let it either upgrade to PG1 of do an emergency firmware recovery on it.

It's the t-mobile variant. Latest update on the phone is APG1.
I used Odin and passed, just to make sure after everything was said and done, I did another factory reset and it says the same thing.
Never heard an emergency firmware recovery before how do I do that? Thanks bud

I am having the exact same issue.
My suspicion is that it's quadrooter.
I installed a game from the App Store that I saw had installed with Chinese characters instead of english.
It was shortly after that that things started going bad.
I am also on the same T-Mobile variant. I will try Odin, but I don't hold out alot of hope to reset.

All the S7 say, (failed to mount/preload......) from recovery. Don't know why, but I have not noticed any issues.
What issues are you experiencing?

This is an option with Smart Manager.
If you are on PG1 or want to upgrade to it, I would go that way rather than ODIN (which you could always do later).

Urgent Help Please

Hello everyone, I will make it short, yesterday I bought a s7 edge which worked perfectly until today when I decided to just restart it, it gave me FRD Error in RED. So I decided to go with a stock ROM (UK) , so I put this rom in ODIN, worked BUT there is this problem that come over and over:
1. I get a "Welcome" screen with language options. I select "English."
2. I get a "Wi-Fi" screen. I select my my wifi.
3. I get this message. "Unable to sign in to Wi-Fi AP. An unauthorized factory reset has been performed on this device. The sign-in screen cannot be accessed."
And I tried everything posible, I used only data and turn off wifi and it took me to "checking process" which never ends up checking.
Please I have been 9-10 hours on this and no IDEA where the problema is.
NOTE: The phone came with ROOT(I requested)
And also i remember a ROM Called AURORA.
THANKS

Tried this? http://www.xda-developers.com/rootjunky/

The OEM Unlock option in Developer Options had been unselected when you rebooted, you must have done this yourself otherwise it wouldn't have booted when you first started the phone after purchasing it when you powered up.
Anyway, it wouldn't have been FRD in red, it would have been FRP, which stands for Factory Reset Protection. This is to stop someone stealing a phone, factory resetting it, then selling it on or using it themselves with a new Google account. The official way of getting the phone back now is to sign into your Google account using the account information that was on the phone when you bought it, or the account details that you setup prior to rebooting. You should be able to sign into wifi in order to do this, I'm not sure why it's not allowing you to.

Don't think that works any longer, or I'll be surprised if it does given the amount of updates from Samsung since then. It's from 8 months ago.

Aurora ROM was only released yesterday. And you asked the seller for a rooted phone? So he installed a completely new ROM, only hours old, and sold it to you?
Really?!
