We've found the following text in the '/system/etc/bluez/main.conf' file
# Default device class. Only the major and minor device class bits are
# Local device class
# 0x400000 - Service class: Telephony
# 0x000200 - Major class: Phone
# 0x00000C - Minor class: Smart phone
Class = 0x40020C
I've tried all sorts of ways to edit this file to change the Class but nothing seems to work.
I've tried editing the file directly from the phone using root explorer, but every time I save the changes the phone reboots itself and restores the original file.
I've tried adb in recovery mode to push the edited file from my pc to my device, this appears to work but again when rebooted the original file is back.
I've tried adb file explorer but this will not find the /etc/ folder in the /system/ folder.
I'm running out of ideas, can anyone help?
