EDLUnlock

The name says it all.

Requirements:

• An Android device in EDL mode
• Common sense to not fvck it up

Supported platforms:

• Windows only, for now.

Supported devices:

• Xiaomi Mi A1 (msm8953) (used as a working example too)

Should also work on:

• MSM8953 devices
• MSM8952 devices
• MSM8998 devices
• ...and every device manufactured before 2018, having a MSM89xx CPU. <br> BE CAREFUL! This list has not been tested. It should work since those platforms uses the same exploit as the one mentioned as an example. <br> Plus, the bin folder only contains MSM8953 patched mbn file. You'll need a working .mbn/.elf file (patched, hehe) in order to use the tool correctly, at least on other platforms.

Usage:

• Double click on EDLUnlock.cmd, then follow the instructions. <br> Inside the repo there already is a .mbn file + the partition (with its specific rawprogram0.xml file) for unlocking a Mi A1 (tissot) thru EDL mode.

How it works:

After some tries (almost 30 lol), found out that the devinfo partition (at least on my tissot, my test device) handles bootloader unlock by having a different hex pattern. Here's an example.

Unlocked bootloader: <br>

Locked bootloader: <br>

The same procedure could be potentially applied to any other QCOM device (with a bit of risk).
