Increased earpiece and bluetooth headset volume

[bjacobso]

I've been getting great info from this site. I'm finally able to give something back. I figured out how to increase the volume for the earpiece and the bluetooth headset.

1) Use P2KMan to download gain_table.bin from the phone to your PC.
2) Edit the gain_table using XVI32 or a similar editor.
3) Change offset 10 value from 08 to 25 to increase the earpiece volume.
4) Change offset E8 value from 08 to 25 to increase the bluetooth headset volume.
5) Upload gain_table.bin from PC to phone.
6) Restart the phone.

There will be some distortion if you turn the volume all the way up, but it lets you hear in noisy places. Info on P2K tools and XVI32 can be found by searching this forum.

Good luck!

Nice post bjacobso. How did you figure out which offsets to use?

[bjacobso]

The old fashioned way -- trial and error (or as my wife would say -- obsessive and compulsive). I started with the gain_table offsets for Vxxx Motorolas and tried changing ones nearby that were set to 8.

It appears that the A780 is set up similarly, but has a few extra bytes stuck in there.

It would be great if you could turn up the speakerphone volume so that way when we answer the phone without opening the phone we can hear better on that and also figure out the same speaker for listening to music. That would be great. And maybe the microphone volume turn up. That would be great if you could find these out. Pm me or repost here. Also maybe a way to turn up the ringtone volume. To make the phone ring louder when someone calls. I used xlr8's gain_table edits for a couple of years on vxxx motorola phones and they worked great. I love this phone but the volume issues have almost caused me to sell it and get another phone. But just these two volume fixes have helped out sooooo much.


Thanks for the find. I haven't tested it out much yet but it seems to have fixed the crappy volume issue.


Thanks,
Matt

I made some edits for you. Try this gain_table.bin file and post your results.

[MrWireless]

Well I see it has been downloaded a few times. What is are the experiences everyone has seen from this file? I seen a few changes on the first 3 or 4 lines so I know there is some changed.

Whoever has downloaded please leave feedback.

[f0x0r]

Why don't you test it and leave some feedback? These changes were made at your request. Just make a backup of your gain_table before uploading this one. If it doesn't work then change it back to the original.

@f0x0r
Is there another possibility to install the gain_table.bin than P2KMan?
Or a way to do it under Linux?
Maybe just copy it with QConsole to the correct directory?
I did not find a file called gain_table.bin in my phone with QConsole

@Ator
Have you tried moto4lin?

"The moto4lin software is intended to be used with Motorola telephones based on the P2K platform"

and the best:
the A780 is Supported:

I couldn't get my phone to connect through Slackware 10.2 so I have recently installed Kubuntu. I haven't had time to try the moto4lin wiki site but it looks pretty straight forward. Thanks for the information swifty!
