The result was the same for me, although this tablet came with custom global firmware. Status sec write data not allowed 0xC002000C. I don't understand what this error code means.Thanks for the excellent work.
I downloaded and ran it but it did not complete with an error.
I think it's because my tablet was originally a Chinese ROM that became unbootable after applying the global version in LMSA.
It may not be possible as the bootloader is also locked.
I may be using MTK drivers and tools incorrectly.
Has anyone else tried this?
