Enter Unlock Code on USA Tmobile Tab with No Dialer?

I go the official unlock code and directions from Tmobile, but they assume in the directions that you have a dialer... does that mean I have to hack my Galaxy Tab just to enter in an unlock code...ideas???
Here's the Tmobile USA unlock directions:
"It is very important that the instructions are followed as listed.
If using a T-mobile SIM card:
1. Put in a T-Mobile SIM card.
2. Turn on the handset.
3. Enter: #7465625*638*Unlock Code#
If using a Non T-Mobile SIM card:
1. Put in the Non T-Mobile SIM card.
2. Turn on the handset.
3. Enter the Unlock Code provided by T-Mobile.
Note: DO Not enter #7465625*638*unlock code# with a non T-Mobile SIM card, as this causes the handset to freeze.
If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked."

The easiest thing for you to do, lucky one, is to get a SIM card from another provider and unlock.
How did you get your unlock code so fast? What did you do? What did you say? Please advice. Thank you.

I called Tmobile and told them I was traveling and needed asap... they sent it over via email... I followed your directions and it asked me for the unlock code, I entered it correctly and it didn't work. I got a message saying "unsuccessful". I did this process 3 times and gave up. Any ideas?

It should have worked. Unless they sent you the wrong code.

It's weird that it doesn't work and now they want me to talk to the "unlock department".....everytime I get someone from Tmobile support, they think the Tab has a phone/dialer in it...it's almost getting painful!

Phone permanently locked to AT&T and need help!

I stupidly wrote down the wrong sim unlock code given to me by ATT on my phone and I guess I entered the wrong code too many times. I called ATT tech support and they said that my phone is locked permanently ATT now.
Is there a fix around this or am I screwed?
Thx

As far as I know, you are SOL and is locked permanently to ATT, unless theres a way to unlock it via the service menu after a code has been inputted wrong.

Go to Cellunlocker.net and talk to someone in support about getting a code that unlocks your sim-locked status. It's not the code to unlock your phone, it's the code that resets the perma-lock state of the phone.

I guess i am SOL i called cell unlocker and they said they dint have the software to do it

Did you try the method listed for unlocking your phone from the service menus - without an unlock code?
I have not seen it explained, but it appears to me that by disabling the SHA256 network lock, you are basically getting rid of the requirement for the unlock code that is cryptographically dependent on the IMEI.
I did it on my AT&T phone and plopped in a T-mo sim and it worked fine:

You might have one other option that I know of that might work, might not work, or might make things worse. It is the "Free unlock" menu method in the general section. I am assuming you haven't tried it already. Normally I tell people to stay clear of it because of the slim chance it could screw your phone up, but in your case, I'd say it's already screwed up.
Follow the directions and see if restoring your "Golden backup" (NV restore) resets the cell locks on your phone. You can also try thing like turning SHA256 "On", or "Off" and see if it makes a difference. The reason the free unlock method works for some and not others all depends on what info resides in your phones NV backup. For some, it restores full phone functionality without network locks (sim unlocked), for others, it restores exactly what is already on the phone's NV memory (still network locked), and for others, it restores a backup that screws the phone up. There is a slim possibility that if you restore the NV data via the hidden menu, you might restore your phones original sim locked state and then be able to use the code with SHA256ON or maybe Off.
The risk you take if you try it is completely yours.
It might help, it might not help, or it could make it worse. Good luck.

Would flashing back to stock rom work? I am still fairly new with android devices coming from iphones so i dont want to mess with it if it has absolutely no chance of working. The phone is still working fine just can't unlock it.
Thx for the suggestions tho

Flashing back to stock is not going to cure your problem. You're kind of hosed at this point. Scott's suggestion is probably your best bet, BUT you could end up with no phone working at all. If you can still get phone service I'd leave it as is and give up ever unlocking.

TO ANYONE WHO IS FOLLOWING THIS THREAD, PLEASE DON'T DO ANY THING TO YOUR PHONE BECAUSE YOU THINK IT MAY BE COOL. Really know what your doing and why before you do try it. You can really mess up your phone. There a lot of good info in this forum, use it. And take your time, read, study, and read some more.

I wasn't able to unlock my AT&T GS4 via the service menu methods, nor with an unlock code I bought online. I was finally able to unlock it via the USB program at FastGSM. It seemed kind of shady but it worked for me...

i am more than willing to give you an assist if you still desire, but you will have to clarify exactly what you did. If English is not your first language, accept my apologies, but I cannot understand you.
flashing a different ROM/carrier unlock/hidden menu stuff are all differing subjects, with differing routes to completion.

yes i am still looking for a solution, i would appreciate your help
what i did is that i bought a service on eBay, he emailed me an apk called Quick_Fix.apk ( to show the hidden menu ) and these are the instructions
Look for the HiddenMenuCall app on your phone and open it, then scroll and select the following menus & sub menus within:
1-IOT(CDG2).
2-LTE setting
3-Operation Mode.
4-Lab Network (V20 will now restart)
Then Turn Off - Insert SIM card and restart and it will be unlocked
that is all i did, and it was supposed to work but it didn't on mine

I see. So you are trying to pull up a hidden menu on your v20?
What setting are you trying to alter? Wireless tethering? Are you rooted (I am going to take a stab here and say no, you arent)?
Are you trying to carrier unlock your phone? I'm just trying to figure out what you are trying to accomplish?

2-then LTE setting
3-then Operation Mode.

[Guide] How to get your MSL code

Alright so I was bored and started poking around trying to find a way to get the MSL. Well after a couple hours of trail and error, I got it! Here's how.
You will need: ADB, ADB Drivers, and a rooted device.
Plug in your phone into your computer.
Run the following (in CMD) :
1: adb shell
2: su
3: am start com.sec.hiddenmenu/.Program_Edit
It should open a menu with your MSL at the bottom. Hope this helped!
I have tested this on Android 5.0.1 and Android 6.0.

You need the MSL to edit APNs, enable / disable bands of LTE, etc. Not sure if you can SIM unlock on 6.0.1. I have heard that people have had success unlocking their devices with the MSL code on 5.0

Sim unlock? No but look through the forums. Also look on the sprint s6 forums too... If your contract is up just do a UUIC unlock under system update. That should sim unlock your phone.

Hey @Poebat, how do we do the UUIC unlock under system update? Every time I press it I get the hands free activation window popping up. I bought this SM-G900P used and unlocked from a Canadian retailer to use here in Canada. I worked fine with my Canadian carrier sim card until I did a factory reset and now it's apparently relocked. I called Sprint and they said there is a region lock on the phone (after giving them the IMEI number) and refuse to help or unlock the phone again unless I set up a Sprint account...
Any help is greatly appreciated.

I would take it to your carrier and ask them to unlock it. After that I would create a TWRP backup just in case.
As for the UUIC lock, you need to have the phone activated on sprint unfortunately.

Thanks for the quick reply @Poebat. If I can't fix the issue by 3PM EST today I will be seeing if my carrier can unlock it LOL. I do have a NAND back up from TWRP from when the phone was actually working with my carriers SIM and want to try and flash that back to the phone, but need some help before I try it. Would you be able to possibly look at the thread I posted with what I'm trying to do and see if you might be able to help?

It was the dreaded "extractTarFork() process ended with ERROR=255" LOL. A lot of people have had it apparently but in all the threads I read on here no one had solved it yet. So I thought I would try the way I mentioned in my linked post.

Bypass lock code?

So I sold this phone on swappa fully functional and the buyer managed to get some kind of lock code on the device and returned it. Anyway how do I fix this since I can't even get to settings or anything without this code? It's not a FRP, it boots to the lockscreen but when you unlock instead of going home it goes to this screen where it asks for a code. What do I do?

Does it show how many digits it's asking for? Is it sprint variant or open market?

I kind of do think it is asking for a netowork unlock code most likely. However, I don't really know how to bypass it because I can't get to the settings to enable USB debugging or anything.

I would suggest trying the Back to Stock zips on it because it wipes everything and see if that works. You can also try and load TWRP and use it to delete the lock screen password files and then flash the boot image so it boots normally and then you should be able to swipe to dismiss the lock screen. Hope this helps you out

I believe in fastboot mode you don't need usb debugging. In fastboot is where the network unlocking happens.
