Users claim the bootloader on the T-Mobile Sony Xperia Z1s cannot be unlocked

Xperia Z1sT-Mobile fans were ecstatic after the arrival of the Sony Xperia Z1s on their favorite carrier. However, all is not well with the smartphone according to users on numerous forums and social networking sites. It is said that the handset doesn’t have a user unlockable bootloader, which means the users won’t be able to flash ROMs on the device as of now. Of course, Sony or T-Mobile could change that with a future software update, but it’s a little surprising that the bootloader is not unlockable by default.

International Xperia Z1 smartphones come with an unlockable bootloader, although it requires a strenuous effort. We’re hoping T-Mobile will patch this with an update in the future as it certainly won’t reflect well on a carrier which calls itself customer friendly. Of course, for users who don’t flash a lot of custom ROMs, this is a non-issue. The Xperia Z1s is basically the same as the international Xperia Z1 but tailored to work on T-Mobile’s networks with LTE on board as well as a few other carrier specific tweaks.
