[Q] AtT NOte 2 unlocked, now using Tmobile, Can't upgrade firmware

MY sister called ATt to unlock her phone when she went abroad, they did. Now she no longer has ATT and is with tmobile. Using the Tmobile sim card, she can't seem to upgrade her OS using the firmware update option in settings. How can she go about upgrading? she currently has android 4.1.2 with the NOte 2?
also if i flash aokp on her phone, but she don't like it, then flash back the original 4.1.2 firmware, would i lose the unlock that ATT did for her and she can't use Tmobile anymore?

Carrier unlocking is separate from ROM. If you can install custom recovery (CWM, TWRP), switching from ROM to ROM is as simple as doing a backup of one, wiping the device, and installing another ROM. Always save a back-up to your computer, and it's also a good idea (much easier in the end) to do a batch back-up through Titanium of all the user apps, so you can simply restore them to the new ROM instead of downloading them all over again and losing the app data.
Factory firmware can be obtained from sammmobile.com and are flashable with Odin (google it).

thanks for the help but why can't she update the stock rom from the settings though when she switched to tmobile? are the update locked to the att carrier?

I wouldn't worry about it too much. The method Planterz gave you will give her the latest firmware. There's at least a few Lolipop ROMs for the Note 2

Idk the site only has up to stock firmware 4.1.2...which is what she already has on her phone, but on the samsung site, it says they currently have android 4.4.2 for the SGH-I317 phone. i don't know how to get that

[REQUEST] 6039S Marshmallow Modem partition

Hey, I'm trying to make the lockscreen work on my 6039A under marshmallow, and I think I need the 6.0.1 radios for that to work so if someone who has an upgraded phone could please upload a TWRP backup of their modem partition for me to test, it would be great. Thanks!

Hi! I have a few days with the phone and I'm dealing with the same issue. Just a question, if you flash r2 MM zip from 4pda with no additional modifications you get the whole mobile data function working (2G, 3G, LTE) but no PIN or pattern lockscreen, right?
Now, if you replace modem partition from 6.0.1, wouldn't it break some 4G capabilities due to different LTE classes?

When I flash r2 from 4pda I get just 2G and 3G but no LTE with working lockscreen, if I flash my modem partition from CM12.1 on top of it, I get LTE but it breaks the lockscreen.
My assumption is that since the r2 4pda is made for the russian model it removes the LTE band used in my country (Band 4) since the 6039Y doesn't support it, when I restore the modem partition from 5.1.1 I get band 4 support back, but apparently Lollipop radios break lockscreen on the Marshmallow version.
Since the 6039S supports band 4 and got Marshmallow I want to try if flashing the modem partition from it would give me both LTE and Lockscreen since it meets the two requirements I think I need.
This is all supositions from my part, I don't really know much about android development, but I won't be sure until I try and I'm willing to test and report back with results.
Which model do you own?

Ok. So we are on the same boat (6039A, Argentina, advanced user but not enough to be even a rookie developer ).
When I first flashed the r2 version I thought I haven't had LTE conection due to a non-supported area, but now I see that the problem comes from the russian baseband side.
So, back to the topic, is the modem partition from 5.1.1 the same as 5.0.2? As far as I see we don't have a 5.1 stock ROM for our device (or maybe I haven't seen to much).

We don't have stock 5.1.1 but we have a CyanogenMod 12.1 rom which is 5.1.1, I restored the modem partition from there, my guess is that stock 5.0.2 modem should work aswell. If you want I can upload the CM12.1 modem partition for you to try on the r2 version, it should give you LTE but break the lockscreen.

Ok, it would be great if you could.
I'll also check with stock modem partition from 5.0.2 (which I'm running now).

Holy crap, I just booted into 6.0.1 and I have both lockscreen and LTE. What I did was mix both modem partitions from CM12.1 and from Marshmallow and it seems to work.
I will test this to see if it actually works, and if it does I will make a thread explaning how to do it.

Congratulations! If your workaround is stable we can manage to include it in zip installer (with developer permission, obviously).

N920P issue to work in UK, upgraded to MM from china firmware N920F help!

Ok im really hoping someone can help me.
Bought a N920F (yup doesnt exist but N920p's have taken a trip to China to be turned into this strange model)
Now the phone was working fine on Lollipop, and model used to show N920V and baseband Sprint it was like a hybrid custom firmware probably hacked up to be used in UK, but download mode etc. showed it was a N920P originally. Now I wanted to upgrade to Marshmellow, before this I made a nandroid backup and also backed up Radio & Efs using app.
Upgraded succesfully with stock N920P and now no network, tried everything. Then thought I could downgrade via flash to Lollipop to no avail as I think its now locked to do so. Nandroid restore not happening as I believe its locked to restore also unless maybe I was on lollipop.
So now im stuck on stock N920p firmware thats not working in UK networks. Im about to give up, is there any solution. Would unlocking the phone in its current state unlock it to UK networks. I hope there is a solution.
Any help to the right direction is much appreciated.
Things ive tried
Downgrade-unsuccessful
Restore Partitions-unsuccessful
Flash N920V-unsuccessful
Full restores etc-unsuccessful
nandroid restore-unsuccesful
Kind Regards

Check if there is a service menu in your settings
It should be named "activate this device"

now the 920p firmware is locked out of the box if it was unlocked sometimes certain rom flashes will relock
as prev poster said activate device is for sprint users only will never work
have you tried to goto network settings and making sure its set for global or automatic.
also is it saying invalid sim or anything like that normally first signs of being relocked.
i paid 34.99 for a unlock from the idone app worked great.

Problem after HEROLTE TWRP and THE GALAXY PROJECT ROM

I am facing a problem. I was experimenting with THE GALAXY PROJECT rom. I turned on developer options and removed oem unlock.I installed twrp for hero lte and did format partition instead of wipe and installed the galaxy project rom. It worked fine but then I revereted to my stock firmware with ODIN. I noticed that I am not able to call any one. I thought i had installed England Firmware on Indian firmware as I faced that problem, so I downloaded the indian firmware again but again it was working on england firmware. I can say this because it was using upday instead of samsung briefing. I thought its a wrong rom again and to atleast make calls installed herolte rom. Same problem. Call ends immediately. My sim works fine in another phone. Any other sim stops calling in my phone.
Can any one suggest a solution of what might have happened.
I just booted into recovery and it mentions there herolte recovery.
Any solution.
Post Note - Rom were fine. Only calling and sending sms is not working. I can receive a text and can use internet over LTE. System cannot read sim phone number in hardware diagnostic. I cannot open aditional setting in phone as it says that error reading sim card.

Reinstall original England rom using Odin. And then install twrp and again install TGP or any other OREO rom you like.
Don't forget to format data after installing tgp for the first time.
Also boot up and reboot once after clean flashing with Odin.
Then flash twrp.
P.S try flashing csc selection by tkkg it may help.
Also which rom are you using nougat or oreo?

I have used Oreo as well as nougat. Problem persists.
Only my current operator aim are not working and rest of the sim are working fine. Service center haa asked me to get motherboard changed.
I was installing indian rom. Now even samsung knox related apps are not working.
So basically you want me to install tgp again and twrp after that and again went back to stock after that.
Do you have any idea why this problem could have been causes. Can rooting mess with physical hardware of phone?

Okay then phone and SMS probably won't work, cause I guess the Indian version is still a nougat but the England one in oreo both your modem and firmware would have been updated and it's not possible to go back, so I suggest you stay with TGP for a while until official oreo arrives in India.
Or else don't use phone or messaging ?

T-mobile G7 Power on Verizon MVNO

Hello,
I recently got a G7 power T-mobile variant and was trying to get it working on safelink wireless a Verizon mvno. I have it network unlocked and bootloader unlocked and have been able to flash custom roms and my sim is detected but I can't seem to get any calls texting or data on it. I've been perusing the forum here reading everything I can on the issue and feel like I'm 90% of the way there but missing something. For anyone that has gotten Verizon working on their T-mobile G7 please help with how you managed to do it.
I flashed RR and then the Verizon modem but that didn't work. I'm going to try flashing back to stock T-mobile to see if I can get some connectivity.
Anyone have any suggestions?
Thanks

I have already flashed a custom rom to my phone that hasn't had connectivity and the issue is that the custom rom you flashed to your phone doesn't have your regional code for ur area and the tz.mbn file needs to be updated with your area's cod or just re-flash another custom rom because it's rare on how many times I have had to erase completely re-installed new and different Operating Systems to my phone just to learn and try different Roms and only twice have I got a Rom that doesn't support my data.

So just try a different rom from RR and it should be able to work? Should I do a comletely clean install like, wipe system then flash or flash stock rom, then do custom rom over the top?
