Bootloader unlock on Tcl
Unlock procedure follows the generic Android flow: enable OEM Unlocking in Developer Options, then unlock via fastboot. Exact availability depends on the model and region — confirm before flashing.

FAQ
Can I root the TCL 20S?
Yes. After enabling OEM Unlocking and unlocking the bootloader, root is Magisk via patched boot image (fastboot). The unlock notes on this page describe the exact Tcl procedure.
Does the TCL 20S support custom recovery (TWRP)?
That depends on community support for this exact model — verify a build exists for its codename before flashing anything. TWRP is not required for root: Magisk installs by flashing a patched boot image via fastboot.
Will root the TCL 20S void my warranty?
Tcl will generally treat a rooted TCL 20S as outside warranty while it is modified. Restoring full stock firmware before a service visit usually restores normal treatment in practice, and consumer law in some regions (such as the EU) may still cover defects unrelated to root.
What Android version does the TCL 20S run?
It runs Android 11, TCL UI. The specifications table on this page lists the full software details.
