Well, I absolutely appreciate your help, but I think I may just have to give up. The instructions seem pretty straightforward:
Downgrade to PB1 by flashing safestrap lollipop file in TWRP
Reboot to safestrap, wipe system, data, cache, then install Restore_PB1 zip file.
Reboot system, everything works fine as Lollipop, including WiFi.
Reboot to TWRP, flash MM safestrap file.
Reboot to safestrap. Wipe system, data, cache. Install PD1 zip file.
Reboot system, takes about 10 or 12 minutes. After selecting English for language, next page suggests wifi connections to attach to but none are available.
Continue thru setup, then drop down the notification bar; wifi seems half lit - almost like a grayed out (with color, if that makes any sense).
Long press on wifi to bring up wifi settings, and switch is in the off position and does not respond to touch.
Other issues include Back button does not work, Recents button does not work, and External SD does not show up.
Please review attached screenshots / camera images from settings screen to confirm installed files. I'm not stupid, but I'm starting to feel that way. What the heck am I doing wrong??
