[Q] AT&T Note Pro 12.2 SM-P907A Sim Unlock Unsuccessful

[akhu]

I sent in my note in for warranty repair due to blue screen freezes. They replaced the main board and reflashed the software. The tablet was previously unlocked and I was using it on T-Mobile. The tablet was sim locked when I received it from the service center. I went through the process of getting an unlock code from AT&T. The imei that I sent in to them is correct but the code didn't unlock the tablet. I recieved a network unlock request unsuccessful response. As a last resort, I went to Cellunlocker and for a fee they provided me with more codes but the unlock code was the same as AT&T. All of the code entering attempts resulted in an unsuccessful response. Has anyone had recent experience such as this? I ended up purchasing a gophone sim card and activated prepaid service for 1 month and the tablet has service with gophone (AT&T). This means that the tablet can get service but unfortunately my problem is network unlocking it.

Same problem

Hello my friend ! I have the same problem as you. I send my P907a repair, they changed the motherboard and locked out the GSM network. I bought unlock codes and no works, it is the same IMEI and as often happens to be the same code.
I do not know if there is a way to unlock GSM network, but whatever I have to do I will, for example change the IMEI. Someone who can help us? Anything is welcome. Best regards

Please someone answer. AT & T no longer supports this pileup, no OS updates, no Roms, nothing ... we are in limbo.

I had a horrible nightmare when I got mine with att. there's something in their system that prevents any new device even if its off contract from being unlocked for 60 days. many reps do not know about this. you might have to wait 61 days and then attempt to unlock like I did. I know it's just a new board but the system doesn't know that. I bit the bullet and got a month to month plan for 2 months. luckily I kept calling in throughout the 60 days trying to solve the problem. so finally on the 61 I explain to the rep what was going on and they refunded my money for the previous two months.

will the unlock code unlock the bootloader too ?

will the unlock code unlock the bootloader too ?

sadly its just a Sim unlock not Bootloader

Is there any way one can contact at&t and pay for them to unlock the bootloader? By now all contracts related to this tablet and warrenty are long gone, i don't think they have anything to loose to unlock it for us, even against a fee
