Had verygreen's CM11 (1-18, eMMC install) on my HD+ and it was working without any major issues -- came back home one day and the screen was frozen. Did a power + N button reboot, and now the CM logo on boot spins incredibly slowly (completely hanging at several points). After a few minutes it will either bootloop or get into CM11 -- if it does make it into CM11, the system will be very unresponsive and eventually reboot on its own [no matter what I select].
Booted into eMMC CWM 18.104.22.168, formatted /system, /data and /cache and reinstalled CM11 1-18 + PA GAPPS. On reboot, I see the exact same behavior (slow/freezing CM logo, eventual bootloop). When it does sometimes make it back into CM, I see my widgets / wallpaper for a brief moment before it bootloops again, implying that my format/wipe in CWM did nothing...?
I then booted into bokbokan's CM10.1 I had on a MicroSD lying around -- I installed the eMMC brick check app from there (which checked out fine, including a test on the full 16gb). I'm trying to do an ADB push now of leapinlar's NookHDplus-factory-2.2.0-plain-stock.zip so I can install it and try to get it replaced under warranty but it either [tried both SD-based CWM and eMMC-based CWM] :
1 - hangs forever (implying some issue with my internal storage)
2 - says transfer complete, but when I navigate to /sdcard/0/ I don't see it
3 - the one occasion I did manage to transfer stock back over and the system could actually see it, I got a '"Failed to retouch '/system/lib/libemoji.so'" error when installing (and yes, I'm formatting /system every time)
In additional, the eMMC CWM behaves very erratically, sometimes taking over a minute to navigate through folders or respond to a volume button click. Pretty sure my internal storage is damaged somehow.
It seems like no matter what I do in CWM, my HD+ continues to try to reboot back into my old CM11 installation. Any thoughts or ideas on what I can do next?
Edit: Okay, so using a 4GB SD card image, I tried to erase /system, /data and /cache and flash cm 10.1 and twrp just to see if anything would stick. Removed the SD after flash, reboot, and the system goes right back into CM11 boot loop. Trying to reboot into TWRP brings 22.214.171.124 back up -- looks like nothing I'm doing will stick. Brought up ADB shell and ran "mke2fs -T ext4 /dev/block/mmcblk0p8" to wipe system, still reboots back into CM11 no matter what I flash in SD CWM.
