Make bluetooth (BCM2045) firmware upload work.
Bluetooth currently seems to work even without that, but since I suppose that Windows Mobile do upload the firmware and a firmware file is found in the Windows Mobile filesystem, I consider it might have some significance.
brcm_patchram_plus should be able to (and seems to be designed to) perform the job, but the bluetooth hardware fails to response after the firmware is uploaded.
The command is supposed to upload the firmware (
BCM2045B2_002.002.011.0211.0000.hcd is extracted from Windows Mobile filesystem):
/system/bin/brcm_patchram_plus -d --enable_hci --baudrate
115200 --patchram /system/etc/firmware/BCM2045B2_002.002.011.0211.0000.hcd /dev
