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...

Completely bricked. BL unlocked, TWRP installed. Won't boot

Thought I was good at this. Never mind.
So I have managed to brick my device after 6 hours of having it.
Managed to unlock the BL, install TWRP, but the OS has gone, and I have no way of getting the thing mounted to copy over a ROM or anything.
What's the best way for me to sort this out ?
I'm thinking I could buy an SD card, copy a ROM to it, then flash it via TWRP.
Is this the only option ?
Help

If you can get to the bootloader then just use the restore to stock tool from shawn5162. Should work fine as long as you have successfully unlocked the bootloader. Here is the link http://forum.xda-developers.com/moto-x-style/development/windows-tool-moto-x-style-pure-edition-t3199905
Should be clear that this will put your device to LP 5.1.1 without root or TWRP. Then just do the OTA MM update and re-root and flash TWRP. You can follow this guide I created if you like.

I have never had such issues when setting up a phone before. Now I have this message
"there's a problem signing in to your google account on this device
Please sign in from a browser on your computer or tablet first, then try signing in again on this device"
Needless to say, I've done this numerous times, and I still cannot sign in on the phone.
Ugh.

Ouch...Thats a security feature on MM... Only way ive found to avoid it is to restore a backup and before you wipe/flash your next ROM either disable the lockscreen(i.e. unsecured lockscreen), re-enable OEM unlocking, or factory reset your device from it from your running phone(not in TWRP) through settings->Backup and reset...that removes your google account from your phone so once you reset it you can set your phone up with your google account

Think I'm screwed. No backup. No ability to log into the OS to reset from within. Just keeps looping on the input screen.
I think I read somewhere that if you wait 72 hours it fixes itself. We'll see.

Why not use the restore to stock tool then before taking the update just make sure your phone has no security on it or the OEM unnlocked turned on...

hmmm thats weird... the new security feature wasn't implemented until MM... The restore to stock should take you to 5.1.1. not sure what else to try. Hopefully you can get in after the wait...next time you get your phone running make a backup to save a headache down the road
edit: you couldnt use the restore to stock then before it loads flash a 5.1 ROM?

Its the stock TWRP backup from either 5.1.1 or 6.0....whichever you are currently supposed to be on.

wait, if this is a new phone and you had added your google account before "bricking," why cant you just sign in using that google account. My understanding is that the lockout is to prevent a NEW google account that was not associated with your phone from being used to set it up

That error means you don't have a 72 hour lock yet. Go to https://accounts.google.com/b/0/displayunlockcaptcha on your computer. Login, hit the accept button, then try logging in your phone. Your phone is not locked out, just to to the website. If you changed your password, though, then you shot yourself in the foot with the Google protection.

yup. I confirmed it. My best guess is that if you are in a custom stock rom, just like with the android pay, it will not work since you are rooted. have you tried with a deodexed stock rom without mods? if it doesnt work, you will have to use lgup and flash the kdz for h918. Then unlock it, and then redo the root once again.

I dont know if traditional method work with this one. First call or send a message to tmobile. Tell them your phone needs a code for unlock and that the app doesnt work, if they can provide you with one. When you have everything needed, turn off the phone, remove the battery and the sim card, insert a simcard from another company and turn on the phone again. (in fact, It is recommended to insert the new simcard before even considering on calling tmobile since otherwise, it would be a waste of time if the box prompting for the code doesnt even appear when you turn on the phone)

I had to call them to unlock and that in itself was more painful than to backup device, downgrade to no root, unlock, root, restore... problem with calling was that they kept troubleshooting the unlock app and why it wouldn't work (just keeps checking and then fails). not sure if an older version of the app would work, but I know on my LGV10 it unlocked while rooted. on the LGV20 it won't work until you unroot.

FRP

I bought a Nexus 6P and after I factory reseted it requests for account. I don't have any more contact with the man who sold me because he has no smartphone for now.
It has the January security patch.
Is there any somehow I can bypass FRP in January Patch?
I saw at YouTube that is able to bypass it with October patch, but couldn't find anything for January.
Thanks.

Hello,

Question... The guy sold you his N6P with his account on the phone that you have FRP after factory reset? Cool story...

He sold me and we did a factory reset. The battery was low so I arrived home to boot up and configure the device while charging, but got stuck in this.
Also, I found a way to bypass it and use the device without Google Account. If I unlock bootloader, complete wipe and install a custom ROM, would the account still be required?

Hey,
Normally, if you enable OEM unlock, unlock bootloader, you may be able to skip setup and add your account.
I usually wipe my phone with OEM unlock enabled and no SETUP/account required. With OEM unlock disabled, setup/account required, even with the bootloader unlocked...
Hmm, so you were able to enable OEM unlock? How did you do, since you can't skip setup, or? And if you skipped setup, you should be able to delete the previous account from settings without issue. I'm confused...
Cheers...

Hey,
Did it involve the use of ADB by the way?
Also, if you got in settings, you can go in account and add yours, no?
Anyway... To my knowledge, when I let OEM unlock disabled and wipe, reflash, I have to add my account after the install. If OEM unlock is left enabled, I can skip setup.
Only way to figure it out is trying by yourself... :good:
Hopefully it will work.

S7 Edge G935A Stuck (Download mode locked by MDM)

It means it's stolen..simple. Go return it to AT&T so the owner can get the phone Back. It was locked by password because the owner had a password on it when it was reset.

Hey guys! I've got today this really weird case, an S7 Edge which a friend reports he founded, Android boots and prompts for a passcode (unknown) and when attempted to boot into download mode a quick legend appears saying "Binary mode blocked by MDM", when I attempt to do a Factory Reset from Recovery I also get "MDM does not allow factory reset". I'm pretty much stucked over here, device is in build G935AUCS2APF2 so my last resource was applying an update.zip (G935AUCU2APG1) from SD Card from Recovery but I get:
"Package expects build fingerprint of samsung/hero2qlteuc/hero2qlteatt:6.0.1/MMB29M/G935AUCUAPG1:user/release-keys or samsung/hero2qlteuc/hero2qlteatt:6.0.1/MMB29M/G935AUCS2APH1:user/release-keys; this device has samsung/hero2lteuc/hero2qlteatt:6.0.1/MM"
I also attempted to wipe user data from "ADB sideload" but obviously all commands except for "adb sideload ..." are rejected.
All comments and tips will be really appreciated, thanks!

The device was locked via boot passcode. Means no factory reset or flashing. It probably was stolen and if it was actually found doesn't mean it couldn't have been reported stolen.

Where did you get South America from? It's near impossible to steal smart phones now. Might as well just throw it in the trash. Plus it's against XDA to help unlock phones for this exact reason. It could be stolen, so even if it wasn't, you won't get any help here because of possibility.

Hey! It doesnt have a boot passcode, what I really can't understand is the fingerprint issue, maybe this device is rooted? Thanks

The answer is this:
The unit was owned by another. Because you reset it ...and the previous owner did not remove their password on it (assuming it was not stolen) then , You need the password to open it up. unfortunately, there is no easy fix for this.
BTW, this is a common problem when companies sell excess phones they have for employees. They forget to get their pass codes and so the phone essentially is unusable until they can fix.
There are way to solve this but you will need to do specific research on this to see if you can find the fix for this type of phone.
