Are You sure this phone has eMMC chip? Latest Samsung devices have UFS chips (Universal Flash Storage (UFS) | JEDEC), not eMMC. Unfortunately, work with USF chips is currently not supported.

Have You removed phone's chip from the device or You found eMMC (ISP) pinout? What CPU is in the board? If possible, please make photo of phone'd PCB in high quality and post it here.

Fast Unlocker · 04-06-2017, 11:47

yes I have removed EMMC from board

Fast Unlocker · 04-06-2017, 11:59

i attach it to you hope that enough

Medusa Box · 04-06-2017, 12:53

Yes, really, this PCB revision is with eMMC chip. Also, as I can see from your Software log, after erasing partitions You have written only "PARAM" partition, but also need to write others. Try to find another PIT file and firmware, and make Factory Repair again.
