Unlocking the bootloader, rooting a device, and flashing aftermarket ROMs are popular hobbies here at XDA. The power user community holds the ability to mod their devices in high regard, and they almost find no interest in phones if they are not able to be bootloader unlocked. Many legacy devices are actually kept alive by third-party ROMs, which are also godsends for smartphones that are standing on the verge of losing official support. LG, for example, no longer makes Android smartphones, hence owners of LG devices might want to settle with custom ROMs in the near future. However, the process isn't exactly straightforward due to LG's bootloader unlocking policy.

LG has a storied history with regards to bootloader unlocking. The Korean OEM used to allow only a handful of models to be unlocked by end-users -- probably due to requirements from carriers. Nonetheless, the company permanently seized the opportunity a few months ago, which means people have to rely on unofficial methods to get their bootloader unlocked. This time, XDA Senior Member Wish39 has come up with a really innovative process to unlock the bootloader of the T-Mobile variant of the LG Velvet and subsequently, root the device.

The T-Mobile edition of the LG Velvet (model number LM-G900TM) is powered by the MediaTek Dimensity 1000C SoC. This makes it a unique one in the Velvet lineup, as all other variants of the smartphone feature either the Qualcomm Snapdragon 750G (5G) or the Snapdragon 845 (4G) chipset. The aforementioned MediaTek platform is vulnerable to a known bootrom exploit, which can be utilized to bypass the bootloader security and unlock the bootloader. Afterward, it's a child's play to root the device.

In case the target T-Mobile LG Velvet is running Android 11, we need to downgrade it to Android 10. This is because the Android 11 firmware for this device already patched the exploitable preloader (aka first stage bootloader). You need a PC as well, as the flashing tool works only under Windows.

Now that we have restored the exploitable preloader on the T-Mobile LG Velvet, we can unlock its bootloader in a jiffy. Thanks to the MTKClient project by security analyst Bjoern Kerler, you don't have to take care of the exploit payloads and other low-level reverse-engineering tools. All you need to do is execute a couple of Python scripts.

Since the bootloader is now unlocked, we can (re-)upgrade to the Android 11 firmware. However, directly flashing an Android 11 KDZ will replace the exploitable preloader, hence we need to opt for a selective flashing procedure.
