Connecting un-rooted Butterfly to PC as Drive letter

well, im still not giving up trying to recover my photos.

I have 5-6 different recovery programs on my PC. (once tried to recover a deleted sd-card).
Yet the PC only connects the Android device only as device, not with a drive letter. (which is required by any of the programs to recover anything.)

I've read around that in android 4+, google removed the option to connect as mass storage (with drive letter). Now i enabled developer options and tried using usb debugging, yet no drive letter. I head of the program PTPdrive and wanted to try that, but unfortunately, this program does not support Win10.

I have an unrooted, stock rom HTC butterfly with access to developer otions. I also read of something like accessing the phone over ftp, but found no real clue to my problem,
i want to connect my HTC to my PC (win 10) as drive letter to run a recovery program on it.

Anyone has a guide or tips, how to get my HTC a drive letter?

I recently flashed cm12 on a nookhd+ from cm 11 and despite several attempts, it unroots my tablet. Any suggestions on how to remedy this would be appreciated.

G900A Unrooted, Keepsafe Location on Android 5.0?

I used to be able to backup keepsafe by copying the .keepsafe folder that would normally sit on my internal SD, but that no longer appears to exist? I use to be rooted on previous devices so decided to go check the /Data/app directory or what ever, but on Android 5.0 my data directly is completely empty. I have a /system directory and such and can view everything, but the data folder is completely empty which puts me in a hard place. Searched every inch of my internal and external sd card for a keepsafe folder and found nothing. It should be around 1GB but nothing of the sort is around. Checked my sdcard0/android folder ,sdcard0/data folder, and all others. No .keepsafe folder to be found yet all my stuff is there in my safe.

Long story short, does anyone know the directory of Keepsafe as of the latest updates and how I could copy its contents? I have no option from within the app to export all files to a separate drive. Would have to unhide hundreds of pictures and videos, and then export them to a different drive, and then put them all back in a mangled order.

G900A Unrooted: Error -505 Downloading Facebook Messenger Fail

No matter what I seem to do, i cannot successfully install Messenger. It downloads perfectly fine, but then it fails and gives me error -505. Cant find anything about an error -505. Cleared data on google play, uninstalled its updates, cleared whole phones cache, uninstalled previous version of messenger, restarted phone, and nothing will allow me to install it. Have 3GB of free space internal.

(Excuse me for posting two different threads. Did not want either situation overlooked.)
