ro.secure=0
ro.adb.secure=0
ro.debuggable=1

broken eMMC flash

Make dump of main flash region to SD card using TWRP: 

dd if=/dev/block/mmcblk0p30 of=/external_sd/dump1.bin bs=1M count=4000
dd if=/dev/block/mmcblk0p30 of=/external_sd/dump2.bin bs=1M count=4000 skip=4000
dd if=/dev/block/mmcblk0p30 of=/external_sd/dump3.bin bs=1M count=4000 skip=8000
