Make sure you are using the busybox chown.

The chown binary that is normally installed on the device only works with user names (rather than a UID as I am using here).

Hi, thanks for this helpful trick, however the bit with the chown intrigues me. I have a custom, rooted ROM image flashed onto my phone but chown gives me a “1002 user does not exist” message or something like that. What’s the mechanism there? Is this a bug in chown? What is it that the non-standard ROM images do that make it work?

Im struggling to get this to work on the Hero. browsing with root/su to /data/misc/hcid/ reveals an empty directory. Would be good if anyone else with a Hero can confirm this as default.

I have managed to successfully complete up to line 10.

Any change of getting your appended/modified hcid_config file to try and push back onto my hero? I’ll post the results here to share with all.

Thanks for pointing everyone in the right direction though. Would be nice if the upcoming API had a simple switch for this, or someone could code an app.

I do not know if this will work on the HTC Hero (or on the modaco ROM) as I own a HTC Dream (this has been tested on both one of JF’s and cyanogen’s ROMs). I suggest you back up your phone before attempting anything.

As for running this in a terminal emulator on the phone, it should be possible (I didn’t do it due to the amount of typing required). It is also easier to perform this change from linux/mac machine than on the device itself. If you decide to attempt it on the phone, the first step would be to become the root user (using su -).

Then remount the system partition RW, this should be possible with “mount -o remount,rw /”. You will then need to edit the files mentioned in the post by hand: ‘/system/etc/bluez/hcid.conf’ and ‘/data/misc/hcid/*/config’ (your ROM might contain an editor such as vi). After that, just restart the bluetooth subsystem.

Will the modaco ROM be ok for this edit?

Is this modification possible by using term. emulator directly on the phone (HTC Hero)? If you, what commands (other than remount) are needing modification?
