Asus Zenfone 2 Unlock Bootloader Method

Asus Zenfone 2 Unlock Bootloader – Some users of Zenfone 2 want to exploit their gadgets to maximum potential and for them, good news is in store. Owners of ASUS ZenFone 2 can now unlock their phone bootloader, which permits the installation of custom ROMs. There are some things to keep in mind, however, and a list that technology enthusiasts should peruse before they start to unlock the bootloader.

ASUS provides the tools necessary for the unlocking, but the first red flag is that by doing so you will lose your warranty. The manufacturer is following the general trend: most producers give their clients the option to unlock the bootloader of the handset but they will make clear that this is done in full conscience by the user. Once the custom ROM is loaded, the warranty is declared null.

The reason for this is that once you unlock your device, the manufacturer has zero control over the software on your smartphone. What is more, ASUS claims that once unlocked, the handset can no longer get back into the default locked state.
