JTAG Samsung Galaxy Centura (SCH-S738C) - ForensicsWiki

So i was following along with the link above with a R740C Not the s738c in the link but non the less the pinout worked and i got stuck at Launch the Riff Box JTAG Manager and use the following settings:

Navigate to the Useful Plugins tab
Select the Direct JTAG Access to Flash Memory Plugin. Note the directions displayed in the window along with supported processors.
Activate the plugin
Choose the MSM7627A from the drop down menu on the right side ** Note this is not the processor but it will allow access the the memory.
Select eMMC SDC3 (via chipset) from the Memory Type & Host drop down.
Check Auto FullFlash size
Select Connect & Flash ID. ** This will not flash the memory chip initially, but will only connect**
Choose the read button from the bottom left corner. This will connect to the device and display the partitions and chip ID.

There is no option for
Select the Direct JTAG Access to Flash Memory Plugin.

so how would i go about continuing with the setp in the link to save this live device and recover a dead few i have?
