Extraction with Flowrebuilder goes well . After extraction we check ROS0 , ROS1 and Bootloader_0 . ROS0 is 4.11 , ROS1 is 4.11 and bootloader_0 lenght is 2F170 ( correct )
Judging from these factors is consider dump is good . Solder SBE to Tristate , patch your dump , flash it then continue with downgrade dongle ( if you only flash your patched backup this will not restore it to..like it used to be ) You need to follow the downgrade procedure , after you flash your patched backup use the downgrade dongle to put it in FSM . If HDD flickers and your USB's have power after you flash your patched backup your are 99% saved from brick .
