[Samsung Epic 4G Touch] jazzneel:
EDIT EDIT EDIT!!

Ok, it appears we finally got this working! Thanks very much to Megatr0n for figuring out how to get QPST to recognize our phone! Couldn't have done this without this/him and everyone else's hard work for who actually figured it out!

Please note, I take NO credit for this discovery, just passing along info from amazing hard work of others!

I got most of my info from this thread (thanks to youngstatus)!

Information on getting QPST to recognize your phone is from the PRL flashing thread--all credit goes to whomever came up with how to do this (and Megatr0n, who found this thread): http://xdaforums.com/show....php?t=1267893

Also thanks to cnstarz for figuring out some steps on this as well!

What this is:

Sometimes when my friends text/call me, it takes anywhere from 3-5 rings on their end until my phone receives the call, and it was a little annoying. I remember I did this trick on my hero, and thought I'd share.

What this does is changes the frequency the phone checks the towers for incoming calls, If you are like me, you have probably had times where you will have phone calls that only ring for like 5 secs and then the person hangs up. So i came across this little trick and it works as follows

The default Value 2=3.015434secs

The value i use is 1=1.507717secs

You can change this to how you see fit, I have tested and noticed there is no considerable drain on the batter at 1 and theoretically speaking putting it higher will conserve battery as your phone isn't constantly pinging the towers but i have never tried that

0= edit: (from jazzneel) I think this is reserved for emergency vehicles, so please do not use this in case! (not 100% sure)

1= 1.507717secs

2= 3.015434secs(Default)

3= 4.523151secs

etc.....

How to do it:

1. Install QPST

2. Make sure you have your phone drivers installed.

2.5 Make sure your Epic is not USB debugging mode, to disable, go to settings>applications>development>uncheck USB debugging

3. On your Epic, with the touchscreen dialer, dial ##8778#

4. Change the setting from AP to CP, then hit Home.

5. Connect your phone to your computer with the usb cable.

6. Your computer will automatically install the modem drivers for your Epic wait until you see the “device is ready for use”

7. Open QPST Configurations. Start>All Programs> QPST> QPST Configuration.

8. Click on the “Ports” tab and “Add a new port”

9. Select the “COMXX – USB\QC Diagnostic” and click ok, in my case the port number was 10, your port number will be different, if you see more than one, disconnect all your external devices such as external HDDs, phones, Bluetooth dongles, ect. If you don’t see a port. Disconnect your phone, restart your computer, connect your phone and try again, you might want to remember your Epic’s port number for future use. If you still don't see a port uncheck the box for "Show Serial and USB/QC Diagnostic ports only" and add all of the USB/Unknown ports. One of them should show an active phone.

10.Open up QPST > Service programming. Select your phone in the "Select an active phone" box and click on "Read from phone" and enter your MSL when prompted.

11.You will see the Slot Cycle Index is at 2. Change it to 1 and click "Write to Phone". Then reboot phone.

12. Once you're finished be sure to set your settings back to normal (go to ##8778# and change it back to AP and re-enable debugging mode)

-Your Slot Cycle Index is now changed to 1. You can verify after rebooting the phone by launching Service Programming and clicking "Read From Phone" again.
