[Q] Unlocking phone

Hey guys,
Looking for some help here. For what ever reason the unlock code that T-Mobile sent me does not work - resulting in T-Mobile giving me a $200 credit which is nice, but I would still like to get my phone working with ATT.
I have downgraded to 4.1.1 to do the free unlock methodhttp://forum.xda-developers.com/showthread.php?p=34661189, but my baseband is still at UVUCMK7. I have tried rebooting the phone into recovery mode and installing Stock-TMO-T889UVALK8-Kernel.zip but although it says it was successful, the baseband is not changed.
Any ideas? Help?
Thanks

What happens when you put in an AT&T SIM?

When I follow the unlock code it works all the way through to where they say go back to NETWORK LOCK and choose option 4. Option 4 is not there.
When I reboot with the ATT sim it simply asks me for the network unlock code.
So Baseband is still: UVUCMK7, Android version is 4.1.1, Kernel is 3.0.31-598701

Once the device is unlocked you will need to go back to an LTE enabled modem. Your previous radio would be your most likely solution.

I have a T-mobile Samsung Note 2 (SGH-T889), that I'm trying to unlock. I have downloaded the file from the links listed here on XDA. I have already downloaded Odin307 and the Samsung USB driver. My problem is Everytime I put connect the phone, open Odin, and put the phone in download mode and add the file to Odin then while it says Please Wait.. (just a few seconds after adding the file) then Odin has Not Responding come across the top. I have deleted all the things I downloaded and re-downloaded them after it did that a few times and its still doing it. I have tried the downloads from different sites and it doesn't seem to make a difference.
Can Anyone Please Help me?
Thanks to Anyone who will take the time to help me.

[Q] SIM Unlock SGH M919 Outside US which was never activated on Tmobile Network

Hello All,
I got a t-mobile s4 from USA which was paid in full and never activated on any network in USA. I am now trying to use an Airtel Sim Card in India and it shows that its SIM Unlocked. On contacting the T-Mobile support they are saying that they cant provide an unlock code because the device was never activated on their network.
I am stuck because all websites providing unlock codes work on the same precondition that the device was earlier activated in a T-Mobile network. I am also not able to get into service mode and apply the sim unlocking fix as suggested in few posts.
Please provide help and suggest me the options. I am not afraid to shell some more bucks to make it work but i need assurity that the method would work.
Is there a way that i can try which doesnt require t-mobile network at all???
My android version is 4.4.2 and device has been rooted now.

To use service mode to unlock, you need to flash MDL modem first. After unlocking, you should be able to flash the latest modem back retaining the lock.
Have you checked if the region lock away app works?

Regionlockaway apps doesnt work...I am outside USA having no access to the T-Mobile network and was wondering whether the steps suggested by you will allow me to unlock the device from service mode despite having no cellular service?

As far as I know, the service mode unlock disables the carrier check and doesnt require cellular service.
Also, the S4s are also region locked. They get region unlocked when activated and used on the carrier network. So, your phone requires both the sim and region unlock.

Thanks for your response. I am a newbie so just confirming the steps that i need to take to unlock the device:-
a) SInce i am on 4.4.2 with baseband as M919UVUF9B4 i would need to downgrade it to 4.2 stock version using the link you have recommended above.
b) Once i am on the 4.2 version i can then flash MDL modem to sim unlock
c) Then use region lock away tool to region unlock.
d) Upgrade it again to 4.4.2 and use my device freely.
Let me know if i got it right

For the service menu to work, all you need is the MDL modem. You do not need to downgrade everything. You should be able to find a way to flash the modem alone.

Thanks for confirming. However, i am unable to find any thread tutorial which talks about flashing NB4 modem back to MDL on NB4 bootloader. Most of the threads talk about flashing modems which are prior to 4.3 and doesnt serve my purpose as in am on the latest bootloader.
Please help in providing any thread link or steps to perform the flashing.
Thanks Again!

Need help unlocking LG G2 LS980 flashed to boost mobile.

Hey, I just need someone to point me to the right direction.
I bought my LG G2 off ebay last year, it came flashed to boost mobile. All I need to do is flash it back to sprint and unlock the GSM on the phone.
I just found this forum and don't know where to start in this process..
Im on 5.0.2
Software version LS980ZVI
Model # LS980
Thank you if you can help

this thread has everything you need
http://forum.xda-developers.com/sprint-g2/general/ls980-lollipop-update-root-sim-unlock-t3357837
After you install TWRP successfully but before you unlock the sim card, You can install the latest version ZVI that is already rooted
http://forum.xda-developers.com/sprint-g2/development/rom-ls980-stock-5-0-2-zvi-flashable-t3303163
for unlocking the SIM card I would use this procedure instead
http://forum.xda-developers.com/sprint-g2/general/ls980-lollipop-update-root-sim-unlock-t3357837

Thank you !!

Since you are on ZVI already, you could try the steps in this thread

Hey I did all the steps and got it unlocked but I cant to get my simple mobile sim card to work.
When I select the network mode global I have full bars, but when I try gsm/umts all my bars go away.
The phone is reading the sim card, but im not able to make calls/text. I Also get a authentication error when I try to update the prl/profile settings

did you do the twoclick procedure to unlock the sim card?
did you edit your apn? from the dialer, dial ##3282#
i am on freedompop so i changed my apn to freedompop.foggmobile.com. Simple mobile might require it to be mvno.att.net or something like that( i used that for airvoice).

Yep I did the two click method but on both of my sims my phone refuses to connect/ find networks. I get emergency calls only.
I used a freedompop sim too and changed my apn to freedompop.foggmobile.com. but it still wont connect to the network. When I go into the freedompop messenger app it says. I dont have any data.

that;s strange. It worked for me as soon as I added my APN. Does your phone see the APN for three.co.uk and 3hotspot when you have the freedompop SIM in there?
I don;t even use the Freedompop Messenger app. i just use the sim for data. i can test the functionality of the sim slot because I have a freedompop CDMA/Sprint sim card along with a GSM one.
there are a couple of other ways to unlock the sim slot-they're all based on the same way so don;t know if anything will be different. there is a simfree.exe and there is a thread by someone named summercat for a 1 click procedure. try one of those

yep thats the first apn I see "three.co.uk"
im gonna tot back to zv8 and try this one more time or im just gonna go with ring plus or ting.
But thanks for all the help.

And you used ##3282# to add the new apn, correct?
I would go down to zve, then do the Ota update from sprint to zvg or zvh, then do the unlock and root and sim unlock. It's worked fine for me on zvh and zvi.

Yep, I enabled the lte/cdma, rebooted, then enabled gsm, rebooted and I got it to say freedompop on the lockscreen but after a couple of min. It went back to searching for networks.
im gonna try zve to zvg with the two click method

Good luck. The way you know it is supposed to be correctly installed is that your boot animation changes for the yellow sprint spark animation to some swirly wavy rainbow. The carrier image gets swapped to a gsm version.

Download the ROM from sammobile.com and flash via ODIN(Make sure it is carrier free ie has no network provider name)
and then download multiwindow toggle from the Google Play Store to get back the mobile data notification button

I tired the multiwindow app but that didn't work but while searching for this app I stumble on another app called QuickPanel Manager, which is a paid app. I got the free version from a different App Market, used that and now I have the mobile data button, hotspot and flash light button in my quick panel.
However, when I click on hotspot the setting page comes up blank..

I don't think you want to try to flash stock Odin roms from another device. That might have bad results!
But you can flash about any custom Rom in twrp. All you need to get them to work on this device is a n910p kernel and a data fix.
You won't get lte only 4g H+ while using unlocked.

I don't wanna Flash any Custom Rom for now as this is my daily driver and have already messed up this phone a lot by flashing different custom Roms .
Now, I am on stock firmware which is fine for now.. Will flash a an update Touchwiz based Rom which also updates the firmware to Nougat.

How did you unlock your SIM card? I can't find anything for unlocking a Sprint Note 4. Everything is for AT&T.

Well, I bought this phone unlocked. So, I didn't unlock it. However, if you can communicate with Sprint and have them unlock your phone if your contract is over with them.
You can communicate with them on FB messenger, they reply very fast

Afaik you dont need to have your contract end with them to request an unlock..I requested an unlock this summer (2017) and still have service with them but the phone is unlocked. I'll probably get an international version anyway cause thats the only way to get LTE abroad

Your rom is not official. As you can see in build number shows. Some weird company name not the samsung build number like "N910PUV2DPK4" etc it should show ike this so it means it was rooted before to make some modifications such as sim unlocking.
If you still want to make sure that your rom is official or custom just go to odin download mode and check binary status and system status if it shows custom then its modified.
Until your rom system is modified you can never apply official ota updates from samsung.
Best way to make your phone fully official is just flash stock rom via odin but your phone may end up sim locked if you are not using sprint sim card and you must activate it via sprint network to unlock it.
so my best suggestions will be just postpone updates and use as the way it is if you are not on sprint network.

Thank you very much for replying.
So if I flash stock rom and I get sim locked, so there is no way to unlock it to work with other sim outside USA?
Second question can I root my phone. Because using root checker it says "sorry root access is not properly installed on this device ". Means my phone is not rooted.
I will appreciate all help. Thank you all in advance
