Many thanks for the ecellent write up. I'm surprised that this hasn't attracted more helpful comments. I found this through Google, and it certainly helped me. One tip: To avoid the finger twisting you described in Section 2.5.7, simply disable the "Auto Reboot" option in Odin. When the flash is completed, long-press the Power button on the SM-520 to power it off, and then use Power + Volume Up + Home at your leisure to enter into recovery mode. Note 1: I used TWRP v3.1.1-0. It crashed while performing a Nandroid backup of my existing setup. When I used the version 2.8.7-0 you used, it worked. Note 2: CM ROMs have been superceded by Lineage OS ROMs. Note 3: If you want to install Gapps, it is best to reboot to complete the installation of the OS first, and then reboot back into TWRP to continute the installation of Gapps.
