New to Android - OTA Update Yesterday - Root?

[hillmom]

Almost, anyway....

I have root, but the latest update kills the ability to unlock the bootloader. I cannot use motopocalypse to unlock the boot loader, and found this nugget in someone else's thread over on Droid Forums:

you must have taken the recent update which patched the exploit/hole it the trust zone.
this can not be undone, therefore you can no longer unlock.
sorry

Sooo.... the reason for my wanting to root was to install Cyanogen. I had it on a Nook Color for a while and liked it, and thought I'd enjoy it on my Razr. Sadly, that won't be the case until another exploit/workaround can be found.

That was one of the biggest reasons that this was pushed OTA, fixing that hole that allowed the bootloader unlock hack.

And imagine how special I now feel, since I missed the boat by only a couple of days.

I'm not sure when they started installing it, recently new devices shipped with a newer version that blocked unlocking.

OK, so here's a question from a n00b to the Android family....

In the PC world, if I don't like the way an update changed my PC, I roll it back. If it's a BIOS thing, I reflash it. In any case, erasing and starting anew brings me back to a place I want to be at an earlier point in time.

In the case of the 9.18 upgrade, the boot loader is now locked, and the vulnerability is fixed. Even downgrading to 9.16 doesn't fix this. BUT - is there a way to erase the phone and go back to an earlier version of code that provides for the ability to unlock the boot loader?

Just trying to learn...

A locked bootloader prevents that type of scale back. You have the original RAZR MAXX or the MAXX HD? The original never had the ability to unlock the bootloader.

[SeanM65]

MAXX HD.

Of course, another opportunity has presented itself. My wife has a Samsung S3. Had, actually. She hated it, and bought an iPhone 4S. Got her number transferred over to the iPhone today, so now I have this S3 sitting here, unused. Hmmmm..... it never had the latest update applied, so maybe I can root *and* unlock that puppy. Something to try, anyway. It's not a Razr, but now, I'm in the mode to see if I can make it work on that phone! LOL
