[Droid Ultra General] JulesJam:
It doesn't matter where you purchased from, just whether or not your model is one of the ones allowed to be unlocked.

The only explanation I have for why OP was successful is that somehow some Droid Ultra bootloader unlock codes erroneously got in the database that is accessible online. We know there is some "master" database that has all of the bootloader unlock codes in it for all of the models. That is how the Chinese code sellers were getting them for us - they had access to this master database. But it looks like what is accessible online is more limited - it only has the bootloader unlock codes for those models allowed by the carriers to be unlocked.

It is possible that whatever process was responsible for paring down the master database to form the database we can access online resulted in errors such that some bootloader unlock codes for models that weren't supposed to be in the online database got in there. We know that some people with Dev Eds have not been able to unlock their Moto X's through the Moto site even to the point that Motorola had to send them new devices. So if mistakes can happen resulting in some Dev Ed bootloader unlock codes being left out of the online database, then it is entirely possible that there are some bootloader unlock codes in the online database that shouldn't be there.

Thus, adrynalyne's web app is worth a try - you may be one of the lucky ones!

And if Motorola employees had access to all of the unlock codes, they wouldn't be giving people new Dev Eds simply b/c they couldn't be unlocked through the website - they would just give them the unlock code. I am sure someone high enough up in Motorola can get all of the codes if need be, but not the customer service and tech reps that we deal with.

My thoughts exactly! I was going to post that on the Moto X 2014 forum to ask. I will go do that now!!!!

I just tried using my retail OG Moto X IMEI + 0 instead of the MEID + 00 and it didn't work. The first part of the BUD for my retail OG Moto X was its MEID + 00 and 00 is the IMEI SV of my Dev Ed OG Moto X. Not sure that any of that makes a difference or not, but that is what it is.

We also know that all the Chinese code sellers needed was our IMEI to get us a bootloader unlock code. So it appears that whatever database they were accessing didn't need the rest of the BUD.

I don't think it is a coincidence that the Chinese code sellers disappeared right about when Lenovo took over manufacturing of the Moto X 2014. I think that the Chinese code sellers were accessing a database in China at the 3rd party plant where the innards of the devices were manufactured. And now that Lenovo has taken over manufacturing, the database with all of the codes is more secured. So since no devs are willing to try to crack the Moto X bootloader or find root for 4.4.4 or higher (and I don' t blame them), if there is no way to get the data out of the online database, our only hope is another code seller.

Of course there is always the possibility that you can get lucky and your device's bootloader unlock code is in the online database so it is worth a try querying it.
