## Why?
Over the past few years, a suspicious number of companies have started to "take care of your data", aka block/strictly limit your ability to unlock the bootloader on your *own* devices.

While this may not affect you directly, it sets a bad precedent. You never know what will get the axe next: Shizuku? ADB? Sideloading? I thought it might be a good idea to keep track of bad companies and workarounds.

If you know of specific details/unlocking methods, please PR them or drop them in the [discussions](https://github.com/melontini/bootloader-unlock-wall-of-shame/discussions)

> Reminder that no matter how nice a company is, <br/>

# Misc info

## Custom AVB Keys

Custom Android Verified Boot keys is a feature which allows you to run a custom OS with a locked bootloader.

It's rare to see a device which supports custom AVB keys, but some devices can be found [here](https://github.com/chenxiaolong/avbroot/issues/299).

## Universal SOC-based methods

### Kirin
Kirin 620, 650, 655, 658, 659, 925, 935, 950, 960:<br/>
It's possible to unlock using testpoints and [PotatoNV](https://github.com/mashed-potatoes/PotatoNV) (Read the readme)

### MediaTek
If you own a MediaTek device exploitable by [mtkclient](https://github.com/bkerler/mtkclient) you can unlock the bootloader using that.<br/>
If it also happens to be an OPPO/Realme device and you need to access fastboot: [lkpatcher](https://github.com/R0rt1z2/lkpatcher) ([web version](https://lkpatcher.r0rt1z2.com/))

### Unisoc
If you own a phone with the Unisoc ud710 or ums512 SOCs you can look into this exploit: [CVE-2022-38694_unlock_bootloader](https://github.com/TomKing062/CVE-2022-38694_unlock_bootloader)

Otherwise, you can also look into this: [Spectrum_UnlockBL_Tool](https://github.com/zhuofan-16/Spectrum_UnlockBL_Tool) <br/>
This: [xdaforums.com](https://xdaforums.com/t/alldocube-t803-smile_1-bootloader-unlock-w-unisoc-t310.4393389/) <br/>
Or this: [subut](https://unisoc-android.github.io/subut/)

### Qualcomm 
There's no Universal Qualcomm method, unfortunately.

Although some of these might work for you:

The general exploit:<br/>
[alephsecurity.com](https://alephsecurity.com/2018/01/22/qualcomm-edl-2/) the bootloader unlock section.

Xiaomi Mi A1 and maybe all MSM89** manufactured before 2018:<br/>
