I have a question and could find an answer, well maybe a few... First if you have an unlocked version of the m9 directly brought from HTC all updates come from them not any carriers? With that being said if you by a T-Mobile version and get an unlock code from them will updates still come from them or HTC?

Unlocking phone has nothing do with updates. If you have T-Mobile version doesn't matter if it's Sim locked or unlocked, updates still come from T-Mobile. If you want updates from HTC you have to buy the unlocked model or Dev edition directly from HTC site.

You can always use the SunShine app and change your device to any model you want.. including the developer edition and then you will get updates straight from HTC.

hi can the T-Mobile Version be unlocked/Rooted?

hi i have an HTC M9 from T-mobile, i was checking the boot loader but it doesn't have the fast boot option, I've played around and i noticed that in download mode the fast boot command worked. so. i was wondering it can be unlocked or if T-mobile Locked it like the Xperia Z1s.
i watched a video on how to root it on "any variant" but theirs have been unlocked, i think they have Developers edition but now im wondering if its just mine that is locked.

yes can verify.. you can sim unlock device. travel a lot so need to be able to pop in a telcel chip. only snag is you need to flash a non-tmobile base rom first, Then it will ask for unlock sim code and your set. can leave it on non-tmobile base rom or like me reflash tmobile rom and your set. hope that helps

When you say a non tmobile base do you mean flash a custom rom onto the device? Thanks ;)

The only thing sunshine does is s-off your device right? Thanks!!!

Yes, sunshine will s-off your device. That will allow you to change cid and mid and turn your device into a dev edition or any other M9 released. Just note the radio/modem of your phone won't change. It won't gain support for other bands, but some may be disabled depending on the RUU you flash.
