Possible to re-lock bootloader on Motorola Razr HD Maxx?

[leeland]

Hi all,

Some time ago, I got talked into unlocking the bootloader on my phone and rooting it by a co-worker...

It never really went any further than that...

Now, 16 months later, I am at a new job and long story short, I need to unroot and lock the bootloader so I can get get on the network for emails and such.

I used the SuperSU tool to unroot the device.

Is there a method that I can use to relock the bootloader as well that someone can help with please?

Thanks,
Lee

I know there is a somewhat complex relock produce, but I believe it doesn't fully remove the unlock, because a certain signature cannot be recreated or something to that effect.

I relocked mine prior to selling, but it still showed up with the unlocked image at boot. I believe it was treated by software as actually being locked, however.

I'll try and dig up the instructions I had followed.

Thanks much in advance, ultimately that is all I am looking for to get the 'green checkbox' on this mobile security software the company uses...right now it is listing the OS as unlocked.

Haven't looked at the link yet, but does this wipe the phone in the process of trying to lock the bootloader?

Thanks for finding that! I have been googling for over an hour and never found that article!

This is specifically for the Verizon Moto X Developer Edition - not sure if it will be of much help. This is, I believe, what I had followed:

Here is some other info - doesn't seem nearly as helpful. lol

Seems like it does.

Quick update...

After F****** around with the standard applications to do this type of firmware downgrade...I spent around 4 hours and two computers and finally got the sequence right after sacrificing a chicken and praying to budda!

Once I got back to work today and went through the gambit of steps I was able to successfully pass the audit even though the phone says it is unlocked on boot up.

Thanks for the tips and tricks guys
