HTC One A9 unlocked edition allows users to unlock the bootloader with no warranty void12
In addition, the bootloader can be unlocked, allowing users to install custom ROMs. And unlike other manufacturers who offer an unlockable bootloader, but then threaten to void your warranty when you do, unlocking the bootloader on the HTC One A9 will NOT void HTC's warranty. HTC also promises that the phone will launch with minimal bloatware, and Android updates will arrive no later than 15 days after Google starts pushing them out to Nexus models.
The HTC One A9 is available to be pre-ordered right now, directly from HTC's website (HTC.com/us/) starting at $399.99. This is a special pre-order price, available for a limited time.
