RAZR HD and RAZR M Updates Fix the Kernel Exploit for Unlocking Bootloaders

razr hd bootloader unlocked

Normally, we like to see software updates to our favorite phones because they tend to fix bugs and bring other enhancements that make them more stable or usable. Unfortunately, that doesn’t appear to be the case this time around with the new updates for the RAZR HD and RAZR M that were approved yesterday by Verizon. While they do improve GPS and eliminate random power cycles, they also aim to patch the kernel exploit that Dan Rosenberg used to unlock the bootloaders of each. In fact, in the changelog, there is a line that reads “ARM Trust Zone Security fix (Kernel exploit allows bootloader unlock).” 

So, if you have yet to unlock your device (instructions), now would be the time to do it. For those who have already unlocked, I was under the impression that a phone couldn’t be relocked afterwards, but you’ll have to refer to the security specialists in the building on that one. As always with OTA updates, proceed with caution.
