[Q] HELP, Note 2 ATT can not connect to network.

i have Note 2 ATT, i am having network connection problem. i can't connect to my ATT network connection . i get circle with line in middle.
i took my phone to ATT store and they tried changing the Sim card and even updating my phone to the latest update, but it did not work.
i tried downgrading my phone to stock Rom when i downgrade the phone. it seems to work fine for five minutes or so i even made a call after one call it started showing same circle with line in middle. i tried flashing all different Rom, i even tried re flashing MJ4 modem. nothing seems to work.
i research to find a solution but i didn't find any solution to this problem. right now i am on Sky Note Air 4.3.
please help me i appreciate for any help.
EDIT: i flash back to stock Rom 4.3 with rooted MK6 bootloader. just to see if it makes any different on my networking problem. And still have issue with not networking data.

Try flashing 4.3 rom from scratch (wiping dalvik cache, data/factory reset and cache partition) ? May be this will help fixing problem
If you want you can try Stock Rom - http://forum.xda-developers.com/showthread.php?t=2589891

Also make sure you have an APN set. @Bajanman has compiled a list of several AT&T APNs in his thread here: http://forum.xda-developers.com/showthread.php?t=2172110

I had a similar issue and this post helped me.

Also check your SELinux setting.
Once I set mine to permissive all was well.

They are not hacking my friend...
Have you verified that your IMEI and EFS folder are normal ?
And have you verified your APN settings for your carrier ??
You mention flashing several roms on the device...
The items I listed will help you determine if any damage has been done....and also help you get service again...
All are knowledge you must have to prevent bad things from happening...
If your carrier did an official update to 4.3 while the device was rooted and running custom firmware....then you absolutely need to start fresh to clean the device up again...
Are you getting Knox errors or force close issues ??
Basically....in order to help you we need a detailed status of the device...
Software version....kernel version ....and baseband.....
The information is in settings/about phone/....and will tell us how best to proceed....g

Reading your first post, ATT flashed your phone to the latest update??? And changed the SIM? And that didn't work?
Why did you leave the store when your phone didn't work?

They told me they can't do nothing about it and the warranty was voided too.

Interesting. I'm asking questions I guess really dont matter.
But why was warranty voided, or was it expired?
Again more confusion.... Just wondering why they changed sim, flashed update, then told you to hit the street with a broke **** phone.
I can understand not replacing it, warranty whatever.
I took an Atrix2 phone into the shop, no working data. I had called tech support, they had OTA refreshed it, didnt work. Set me up with tier 2 tech support, more resets. Nothing.
Went into store, got another sim. Turns out it was simple. I had turned off the data plan awhile back until I was ready to give it to my daughter.
Got online, picked a plan. Data lite off.
Point is they worked with me to find the problem on a phone that was 2-3 years old.
You probably should follow me how to in this section and flash the stock 4.1.1 and go from there.

[Q] I am trying to unlock T-Mobile S4 from ebay

So, I recently bought a galaxy s4 from ebay, and it seems to work on the network, so I don't think the IMEI is blacklisted. However, when I tried the steps here http://forum.xda-developers.com/showthread.php?t=2282683 and here http://forum.xda-developers.com/showthread.php?t=2283068, I am unable to complete the process. When I do the latter, which seems more like what I did with my S3, I get the same message "unable to process request". I remember I was getting this message on my S3 when I had the SlimKat ROM on it. But when I look at my S4, it looks like it has the OEM ROM on it, so I am not sure what is happening. I looked at my boot loader/baseband, and this is what I have: m919uvufnh7. I know that with my S3 I had to make sure I used the correct ROM to flash my phone, so I could get it unlocked the free method. So, does anyone know what bootloader and ROM could help me accomplish these steps in the second thread?
I am thinking I should flash a different ROM on my phone.

Have you tried contacting T-Mobile? If the phone is paid for in full, they are supposed to unlock it for free.

Thanks for the response, but I have not tried it, because I don't think it is that easy. I also purchased AT&T tablets and tried unlocking them, but AT&T said they were 'active' under someone else. They were not not showing as stolen, but active. I am not sure what that entails, but I am guessing I have to register it under my account first, before I can request to unlock it. So before I try going through the long process of figuring out how T-Mobile can unlock my device, I thought I would give this a try. It seems simpler and since I plan on modding my phone after I unlock it, I see it as just part of the process. (At least I hope so.)

I will try this. But I was trying to make sure that there was no problem with downgrading, as I am currently on 4.4.4. And I know that on my S3 there was a big warning about downgrading from 4.3 to 4.1. To avoid bricking my phone, I thought I would ask and make sure.
So thanks again to both of you for the responses!

Alright, I was able to get mine to work, so maybe I will list my steps. However, I must say that I had some failed attempts (in part due to not understanding the post referred to by radoo7701) and some issues with my phone. But those steps wont be included. Also, my version was m919uvufnh7, not NK2. I would think it does not make a difference, as long as you reflash back to NK2 at the end.
1. I locaed the modem for M919UVUAMDL and m919uvufnh7 modem (as I did not make a backup of mine before starting)
2. I used Odin 3.07 to flash the AMDL modem
3. I tried the steps here http://forum.xda-developers.com/showthread.php?t=2283068, but this would not work, I could not even get the menu to pull up, as it would say request unable to complete. So I tried this http://forum.xda-developers.com/showthread.php?t=2282683 and that actually worked, so I went through these steps successfully.
4. Use cf-auto-root to root your phone
5. Download regionlockaway and transfer it to phone, then install it on phone and run it.
6. flash m919uvufnh7 modem and booted up with my AT&T sim, and it did not ask for unlock code. It just worked!
NOTE: I did have to use a T-Mobile sim card to do the menu process, but radoo claims that he did not do the menu portion. I had already done the menu portion when I finally got to reading his comment. So I can't say that it will work or not. Either way, his suggestion worked for me and I am content with the result!
Thanks radoo7701!

Please post link to files in step 1 you specifically used. And also links for step 5 you used.

I think i've bricked my phone

I have what I thought was a n910f so a root was possible but when in download mode it shows up as a n910a which I didnt notice. I used kingroot which also showed my phone as a n910f and when my phone rebooted it said return it to at&t because it was running unauthorised software. I was running 4.4.4 does anyone have any information of how I can fix it please?

Ok, so the samsung kies did not fix my Note 4 (SM-N910A).
I did find this:
http://androidromupdate.com/att-galaxy-note-4-sm-n910a-stock-firmware
downloaded the 5.1.1 package which contains, not just the AP file, but the BL, CP, and the CSC... ALL 4 Must be flashed with Odin 3.09, at the same time.
My phone is now working again.

Did anyone fix their phone yet?

Hi, I'm in the soft-brick syndrome.
This is my first go at rooting my phone (SM-N910A) - at least i was smart enough to try it after i upgraded
anyhoo, i researched and read. i installed my usb drivers, odin, and downloaded the suggested firmware. i couldn't talk between my computer and phone; so, i tried kingroot - big mistake. it failed in the middle and now i'm getting a startup error that says secure fail: kernel, then the blah, blah, blah go to AT&T store blah blah blah.... error.
i finally was able to reinstall the usb drivers and believe that odin can talk to my phone, but i receive a fail message when i try to install the firmware.
what to do? please help.

hey pal im in the sameboat ,and like you i also made the fatal mistake of using kingroot. only cause i used it on SM-E700M and worked fine so i tried it on the note 4 and now i have no clue what to do next should i try to re root it again or maybe try to install the lolipop system it came with or do i try to upgrade or maybe try and install original firmware i can really use your advice what do you think?

no progress yet. i tried loading 5.1.1 and the original version (4.4.x ... whatever it was). both failed. i think that i might be approaching the issue incorrectly.
i think that i might have rooted the phone but tripped knox - when i startup i see in icon of a padlock that's open and it says custom underneath. but i get the error stating about non-standard software installed. i'm going to continue to research and see if i can figure out how to reset / remove knox.
i saw that there was someone who went back to ATT to have them reset the phone ... does anyone know whether they'll do it? at least i could have the phone at a "ready" state to try again ... after more research and prep. ;- )

not real progress, but...
i researched some more and feel as if i made some progress with odin3v1.85.
i followed directions from this article: How to Unroot / Unbrick Balaxy Note 4 (i found on the androidrootz site - sorry, i'm not allowed to post a url yet)
so, i'm still bricked, but this process was able to communicate with my phone and reported that flashing the firmware was successful.
incremental progress ... maybe ...

my solution
while i would have preferred to be able to figure it out, i couldn't.
i took the phone to AT&T today and they re-imaged it. all is clear and it's back to factory settings - no cost.

Unfortunatly, once you are on 5.1.1 there is no downgrading back to 4.4.4. Many have tried, non have suceeded. Am I saying it is impossible, I do not believe anything is impossible, but right now we do not have the right tools. Take care.

Yah. I tried had to reinstall the 5.1.1 firmware again. 17step procedure is a lil more than im capable of. Think the note 4 is getting sold. Moto x pure or another nexus. Thanks you guys on here it's where I got the firmware.

Yah I wouldn't try anymore to root, if theres a huge bounty and none of these smart cookies here on xda haven't got it yet. The 910a variant is unrootable perm root that is, the. Mobile version you can. Glad it helped and your up and running again.

Activation issues

I just bought the Virgin Mobile data done right Samsung Galaxy s3 L710T, I turned it on and it is stuck at the initial activation screen. I contacted Virgin mobile and we factory reset the device. To no avail... They are incredibly unhelpful and I'm hoping somebody else has a suggestion on how to fix this. It goes between no network retrying. And activating your device please wait. I can access the top menu bar but nothing else. Helppp also note I have full lte access and WiFi I can toggle so there isn't an actual network error...

I guess they are still on shelves then.
I'm also suprised VM attempted to help you with support, seeings as DDR is a special Wal-Mart/Virgin Mobile deal and they usually don't offer support and pushes everything related off on WM.

If you don't resolve your issue and want to sell it, I am interested.

I would be willing to pay a developer to help me solve this.

I am almost pretty sure this that 'Activating your device" screen can be bypassed by maybe editing the prop.build file (I remember having similar issues with another phone of another provider about 2 years ago, while I wasn't able to specifically determine the name of the binary/executable responsible for that screen to eliminate that file through TWRP, all what I know is that it has a window that says "Self Service", but I was not able to detect such process called "Self Service" in either /system/app or /system/priv-app so I ended up installing a custom rom that didn't gave me that headache and the phone worked beautifully.
Perhaps, you might want to install a custom rom, a Stock Based custom rom since stock based would offer the greatest stability, then you can decide to root it if you want (unless that rom that you pick already comes pre-rooted).
You will need to install TWRP recovery to your phone first.

I have twrp installed already. I'm having trouble finding a custom rom for the L710T on Virgin mobile data done right. Do you have any suggestions. I've since bought an LG v20 but am interested in repairing this phone if at all possible.

Sure, I will be more than happy to help you get that up and running, for now post here what's the model number of your phone so that I can source for you the correct custom rom for your variation of L710T.

I do not have the /DDR partition

Confirmed working. Also you can dd the partition in the TWRP CLI if you know the block name. Which for me was 20. I ended up restoring a blank.img over top instead of DDR as I did not have a DDR partition. Thank you so much for the help!

Convert/Upgrade the AT&T G6 to H873 OR US997 With VoLTE

Lets get those warnings out of the way! Warning Do this at your OWN RISK! There is NO WAY BACK to AT&T firmware at the moment and might never be. Only loss is you'll loose VoLTE and WiFi calling (If using the H873 Firmware)
Idea came from this thread which also perfectly works on the AT&T model! https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966 Its the same method.
We finally get Network Selection AND being able to Disable LTE as well for those who like it, and removing the carrier branding in the top corner. (See screenshots)

Flashing firmware won’t unlock the device (any device for that matter) You need to unlock the device by unlock code.

Curiously the thread you've mentioned in the OP (https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966), claims to be able unlock the SPRINT variety only by merely flashing it with an "open network" type firmware.
In my experience, I've never seen any phone, ever get unlocked by merely flashing a firmware (even if it's "open network" type).
Usually the network lock information is stored in a non-volatile security zone, so this just doesn't make much sense.
Now, I'm not doubting the OP, it's just extremely unusual, but it could be an anomaly or firmware bug.

Well this thread is not for unlocking the GSM model which it CANNOT. It’s meant for having a generic open firmware removing all the AT&T junk. Meaning if it’s not unlocked it won’t be unlocked after flashing.
Now the Sprint model is CDMA which is completely different than how GSM works. Sprint CDMA phones are usually software locked to keep it from being used on GSM networks. That explains that

Getting moisture in charging port and another popup that asks if I want to keep it as a charging device for another phone. I'm sure it's a minor bug and a restart fixes it but I'll be trying to update tomorrow. Saw on a Korean site that there's newer options.
No regrets by the way. So nice finally having a modern os

Works perfectly, thank you very much!
But one thing: I had to start LGUP.exe with admin rights. If not it was not possible to choose the kdz file.
Btw...is there a way to remove Facebook, Instagram and the hole sh*t? For sure i choose remove LG apps as well but these apps still there.

Not without root

Got ya! Well now it makes sense... first, the description "unlocked" is a bit misleading, a more accurate description would be "un-branded" firmware. Second, on the Sprint side I can see how the open-firmware could "unlock" the network, course that would disable the CDMA side, only GSM would work.

Yes, here's how to disable any app WITHOUT root.
First, save the app list into a file with this command issued from your ADB folder:
adb shell pm list packages -f >c:\Apps.txt
Look through the saved file (c:\Apps.txt) with any file viewer/editor (like Notepad etc.), search and find the app's name you wish to disable.
For example, the Facebook app:
package:/system/app/Facebook/Facebook.apk=com.facebook.katana
Copy and paste "com.facebook.katana" (without quotes) into this command line:
adb shell pm uninstall -k --user 0 com.facebook.katana
The above will disable the Facebook app till you factory reset or update your phone's firmware.
Just repeat the command for all other apps you wish to disable.
Enjoy!

The H873 kdz works which was the point of this post.
There is no H871 flashable firmware out yet and quite possibly won’t be.

It wouldn’t have anything to do with the firmware unless 1. The LCD is for a different model or 2. Your phone is not a H871
