Can I update my Moto X?

[pmo011]

I recently bought an unlocked 1st-gen Moto X from eBay. I use T-Mobile and the phone itself turns on and works fine with my SIM card; however, I'm stuck on stock 4.2.2. When I try to update in the normal interface, I get an error message stating that "check for update was not available at this time." Looking into it further, I found out that my phone is an unbranded model XT1056 (the Sprint one, as opposed to the T-Mobile XT1053) that has been rooted and unlocked. I've tried going into the loader and flashing all sorts of different updates to the phone, including multiple T-Mobile factory roms and official Android updates, all without success (they automatically abort before they start.) I have a feeling that the reason I can't update is because I'm using a Sprint phone on T-Mobile firmware, and this is somehow confusing the phone into thinking the updates aren't compatible. Is there any way for me to update Android on my phone?

It appears Motorola has instructions for manually installing updates, you might try that.
