What are the advantages.

Advantages:

• Latest security changes that include security fixes in 4.4.4 revision.
• Supposedly, fixes blue-tooth issues.
• Some say better battery life.

Disadvantages:

• Security fixes which means Towelroot exploit is patched.
• Security fixes - in original KK OTA for this phone, you could unlock the bootloader. If you take the latest update and haven't unlocked your bootloader, you will be SOL for unlocking the bootloader AND rooting the phone.
• Some say battery life is worse.
• Some say blue-tooth isn't fixed.

I'm trying to help my buddy root his Razr Maxx HD, but he already took the 182.46.15 update, which breaks Towelroot. Is there a way to flash back to 182.46.10 so he can use Towelroot & unlock the bootloader?

No. Once he took the 183.46.15 update, the trusted partitions that would have allowed you to unlock the bootloader were overwritten and there is NO way, repeat, NO way to revert back to the previous version. It won't allow writing to those trusted zones with older versions. There is NO way to fool it due to checksums, so don't try or ask. It's been asked thousands of times all with the same answer.

Can you not use the method of unlocking the boot loader found on motorola's website to unlock and root?

No. As I said, there is NO way to unlock it, legally or illegally.

The unlock tool on Moto's site is for a select set of phones. The XT926 is not one of them.

Face it. There is NO way to unlock the bootloader now that it's on 183.46.15. That option is gone. I don't know how much more I can stress that fact.

No, you cannot unlock .15 yet.

Thos method only works for unlocked bootloader. This was made up for phones already unlocked which have lost root access after an firmware upgrade.
