Can anyone shed some light on this for me. I found it while running strings on an lk.img. All I have found is "ultra-flash" and "OEM ULTRAFLASH_en" and "OEM ULTRAFLASH:" In a little testing I found that it allows bulk transfer and flashing of protected partitions I believe. Or at least bootloader area is opened. Can't find any reference to it online anywhere so far. I have found it in multiple MTK firmware but no documentation for it in 6 months that I've been keeping and eye out for. I found it July 3rd of last year, why is it such a secret ?
