However, flashing this phone in any Sp flash tool, is ending up in:
ERROR : STATUS_SEC_PUBK_AUTH_MISMATCH_N (0xC002001B)
The
PUBK_AUTH part of this error message, is the
Authorization for flashing Signed/verified image files. In the Oukitel WP17 firmware folder, downloaded from
Oukitel Downlod Center, are their only certain files marked as verified.img, and now after testing in Sp flash tool, loading ALL non-verified files, you can flash these files to the phone without problems.
