Not sure what else to suggest. On the XP machine I did this mojo on I also had ActiveSync installed - possibly disable AS USB connection option...

You say modem mode was being picked up. I assume you installed the modem drivers for using USB tethering? I *did not* have that installed on the machine I did this with, its possible that the two sets of drivers can't coexist?

Everytime I try to point the harware installation to that folder, it doesn't accept the files.

It will whine and complain that the above drivers are not signed and/or are possibly not the right drivers for the hardware - you should tell it to install them anyway.

Changing the slot cycle index is worthless on Sprint, the tower overrides it. Any change you have experienced is placebo effect/coincidence.

Changing the voice codec, however, is a good idea!

Hmmm... I am not sure, as when I do ##debug# it shows the slot cycle as 1 if I change it to 1. I don't doubt the tower can override anything the phone suggests, but I also understand the concept of a client expressing its desired settings to a server. So perhaps this setting is the phone's "desired slot index"?

Anyway, check your ##debug# output and tell me you're not getting a 1 slot index when you've set the phone to 1 vs 2.

Ah yeah - googled around for this, and it seems there is a couple of different ideas on it.

"Larry" over at sprintusers is sure no phone setting matters for slot index.

Seems to say what I say - that at the CDMA level, it should pick the smaller of the two (tower or phone)

II TECHNICAL QUESTIONS

Q 2.1 In CDMA what is meant by "slot cycle index"?

A 2.1 [Credit: Bill Walker]
On the CDMA Paging Channel (this is the shared channel that all phones
listen to for incoming calls and other control info), time is divided into
"slots". To conserve power, phones that are currently idle only "wake up"
and listen for messages on the Paging Channel during their assigned
slots. The slot cycle index determines how often the phone's slot comes
around. If the slot cycle index is 0, the phone wakes up every 1.28
seconds. If it's one, it wakes up every 2.56 seconds. If it's two, it's
every 5.12 seconds, and so on. The larger the setting, the more power is
conserved, but the longer it takes to page the phone for an incoming
call. You can imagine that if it were set to 10.24 seconds, few callers
would hang on the line long enough for you to answer your phone.

There are two settings that govern this. One is the "preferred slot cycle
index" in the phone, and can be set via service programming. The other is
the "maximum slot cycle index" set in the base station and broadcast in
overhead messages on the Paging Channel. The phone has to use whichever
number is smaller.

At any rate, changing the slot cycle index while you're in there mucking about can't have any negative impact.

Thanks, I'll play with it this weekend (I'll try installing on another computer).

As for the drivers, it give a msg that the driver doesn't support my hardware and doesn't even give me a chance to install them and get the unsigned trusted driver warning.

Im having the same issues with the drives, its refusing to acknowledge the inf's as anywhere near valid for the device. Ive tryed it on a machine that i AS with and one that has never seen the phone before (both XP, admin rights) I am running AKU3.3 can you zip up your edited drivers and PM them?

**schettj** · #17 (**permalink**) 01-26-2007, 01:10 PM

Ugh... no drivers, its not gonna work at all.

You have to get those drivers installed - you sure you followed that guide exactly?

http://www.ppc6700users.com/forums/v...ic.php?p=20335

Download the drivers attached to the first post, not the link...

EDIT the files before you try the install, as the post says...

Start the phone DIAG, then plug in USB...

XP should ask for the drivers, and if you edited the .inf files right, they should work with your phone.

done, done, and done, after a couple of resets on the phone and a reboot of the pc, it just started to reconize, before the computer was refusing to reconize it as a valid usb device

ElPasoGuy · #19 (**permalink**) 01-27-2007, 01:23 PM

I tried it on another computer and was able to install one driver, IDing one new hardware device. In order to do that, I had to stop the #diag program because it wasn't doing anything.

Then I go the yellow caution on that device and it was never available again.

I think I'll give up on this. Thanks for everyones help and support.
