What are .xx files? 4.1.2 supports MTP and MassStorage, but you have to enable MassStorage (-> notification dropdown -> select notification)
I'm sorry for not explaining clearly...
I was using this 4.2 jellybean ROM
when I plug in my phone through USB, It says my phone is Portable Media Storage.
Then I flashed another 4.1 jellybean sense Rom. (ARHD 15) (wiped and flashed new boot.img)
I manually copied the things from /sdcard/0 to /sdcard
then delete the directory 0
now when I plug in the phone it still is portable media storage
and there's also an additional driver installed...
"HTC sync (cd drive)"
The drivers are installed automatically when I plug in my phone
And there's no other plug in mode
what should I do?
