[ale] Things I have learned about the HTC One m8

[Charles Shapiro]

Boot loader unlock//clockworkmod install//rooting this device is relatively
easy. Thanks to HTC's goodness ( http://www.htcdev.com/bootloader ) no
exploit or weird software is required, assuming your carrier allows it (
Verizon won't ).

Mass storage is not organized the way you think it is.  There's still an
'/sdcard' directory, but it's internal storage. The external card is on
'/sdcard2'. Clockworkmod mounts it as '/storage/sdcard1' and provides an
option to back system memory up to it.  If you back up to '/sdcard', your
backup remains inside the phone -- a Trap for the Unwary.   CWM's 'install
zip' menus also have an option for installing a zip from /mnt/sdcard1, so
you don't necessarily have to use adb to push the zip to the internal
sdcard directory.

On Android 4.4, the developer options are hidden. Enable them by going to
Settings->About->Software information->More and tapping "Build number" 7
times.  Without this step, you cannot enable Android debugging and cannot
connect to the phone with adb.

When you connect to the phone with adb, the phone will display a window
identifying your computer and asking if it has permission to connect.
Without this permission, adb will see your phone but list it as
"unauthorized".  I'd betcha dollars that you won't be able to actually read
or modify storage on the phone without authorization.

Android 4.4 apparently has disabled USB mass storage to the phone in favor
of Microsoft's evil MTP protocol (
http://en.wikipedia.org/wiki/Media_Transfer_Protocol ), designed mainly to
facilitate DRM controls on your devices.  There may be a way around this.
Linux MTP drivers are apparently buggy and troublesome. I need to do
further research.

CM 11 daily build 20140704 installs and runs, as do the Google Apps for cm
11.

In order to import your contacts from a .vcf file, you must have the file
on the internal '/sdcard' directory.  The simplest way to do this with CM
11 is to copy the file to the physical sd card, insert it into the phone,
and then use the file manager to move it over to the correct directory.
Delete the .vcf file after you're done, as it's not encrypted.
