[Upgrading, Modifying and Unlocking] summersolstice:
Hi guys,

I'm struggling to root Crosscall Action X3 phone. Please help.

Official site from crosscall has no firmware or root instructions.

Cannot find any custom rom online.

Recovery says this is some Hisense type of device (HS8937QC).

Usb debugging and OEM are turned on in the settings.

Tried kingoroot, kingroot, towelroot,oneclickroot, drfone root. None worked.

ADB and fastboot apps installed on my computer, but commands to unlock bootloader do not work (details below).

Noticed something unusual; there seems to be limited access to root partition? Is this normal?

Phone details: Crosscall Action x3

Android 7.1.2,

Qualcomm Snapdragon 8937 cpu

Full specs here:

Maybe someone here knows how to unlock this phone?

I cannot find any details, anywhere, not instructions, no stock rom, nothing. Googled long and hard for hours, even translated webpages from french, russian and korean to english but there is no useful info.

Thank you guys. Really struggling here, hope someone can help.
