This tool will allow you remove the Tampered flag from your bootloader. It will also allow you to easily Lock and Unlock your Bootloader directly from recovery.
No root required since it is run in recovery, however you still must be S-OFF.

Before using this tool you need to be sure you are using the latest version of recovery as the M7 U/UL TWRP requires at least version 2.6.3.3 for this package to work. The current downloads for both CWM and TWRP can found below:

The latest M7 U/UL TWRP can be downloaded HERE.
The latest M7 U/UL CWM can be downloaded HERE.

***[UPDATE] - It seems that the latest TWRP 2.6.3.3 has been pulled due to some minor issues. If your TWRP version doesn't work please use CWM for now until a updated TWRP release is made.

This will work for Verizon and Sprint as well, however they have different versions of these recoveries, so please make sure you are using the correct recovery for your device.

Saying this again in case you missed it: YOU MUST BE S-OFF!


To use the tool simply copy the zip file to your phone and then boot to your custom recovery and choose install. Then browse to where you copied the file and select it. The aroma installer will begin. Follow the steps outlined in the pictures below and choose the options you want to run.

Now you can just keep this file on your phone and Lock and Unlock at anytime without a PC and without losing data.

S-trace for originally discovering the location of the lock status flag. See this thread.

scotty1223 for his ADB shell commands. Threads HERE and HERE. Scotty was also very helpful to me in understanding some of the default values.

Just to be clear I did not just copy and paste scotty1223's commands into a aroma installer. The echo command can be problematic in aroma, so I developed original code for all four commands. The end result is the same in that the data in the partitions is changed as needed.

If the installer stays on this screen fore more than a few seconds, then it means you need to delete/format cache. This can be done within both recoveries. You may need to reboot recovery after clearing cache and begin the installer again. This seems to happen more on CWM than TWRP.

If the installer runs but your bootloader doesn't change, it is proably one of these things:
  • You are not S-Off
  • You do not have the latest version of recovery (I recommend TWRP)

Nice :) Thanks @crushalot

Quick question (if you have time): why do we need latest recovery? what would happen on an older recovery?
On older recoveries, the worst that could happen is that it may not work. It won't hurt to try.

The reason you need an updated recovery is because on TWRP before version 2.6.3.3 the partition wasn't writable so the actions didn't work. Older CWM should be ok but I only tested the latest.

Hi crushalot, I just noticed TWRP version 2.6.3.3 was pulled and back to 2.6.3.0, just FYI

Awesome that this can be done fron recovery, let alone in an Aroma install! Looks good! :good:

But I am having trouble seeing the use for me personally? Is this so that Ican lock my botloader and download Official OTAs (if thats required)? Or is this just something in case I have to send it off for service?

Or am I missing something here?:confused:

. Warranty purposes. Or for example in my case if I decided to upgrade my phone with jump, I can make everything look like never even happened. It's quite useful.

Yeah, seems like it was pulled because the charging while in recovery doesn't work correctly.
It still works for everything else. Not sure if they will just re-release 2.6.3.3 when fixed or make a new version.
I will update the link and info in the OP.

Thanks

Also sometimes a locked bootloader is needed for promotions like the 25 GB of Google Drive space.
There can be a variety of reasons one might need to toggle it.

Looking and unlocking won't wipe data? Like a typical htcdev unlock does?

    hy

    I just want to ask is this mode actualy locks the bootloader or just change the text?
    eg. if I change status to locked and remove the tampered flag, will I be able to flash roms and recoveryes or I need to change status again to unlocked to do that?

    Tnx

    Yes, it really LOCKS the bootloader, Not the text, the real thing.
