Hi team did you find good news here?
if so kindly upload mobicel metro 2 bin file,
mtk 6571 NAND chip.
" Please do note that it is like Mobicel to us differing chips one and the same device model. This has been noted on the Mobicel Metro 2 (where while most had EMMC, few sets with NAND chips were noted) and the ROMs of these two were not cross compatible. A Memory Test on SP Flash Tool should be able to reveal if this is the case with your particular set or not. If you get NAND not detected/ then you have and EMMC - and vice verse. "
