[Guide] Shorten WiMAX (4G) Reconnection Time After a Loss of Signal

---

Originally posted for the HTC EVO 4G WiMAX connection issues: http://forum.xda-developers.com/showthread.php?t=726877

Requirements:
Your MSL code (See Here: http://forum.xda-developers.com/showthread.php?t=697487)

Instructions:
Turn OFF your 4G radio if it is turned on!
1) Click on phone and dial ##DATA# (##3282#)
2) Click on "Edit Mode"
3) Type in your MSL code (see above if you don't have it yet)
4) Click on the menu entry "WiMAX"
5) Scroll down the list and click on "WiMAX_Scan_Retry(s)"
6) Enter the number 15 and click "OK" (This equals 15 seconds instead of 300 seconds)
7) Scroll down the list and click on "WiMAX_Entry_Delay(s)"
8) Enter the number 0 and click "OK" (This equals 0 seconds instead of 300 seconds)
9) Press the "Menu" key and click on "Commit Modifications"
10) Grab a cup of coffee, get a bite to eat, or sit back and wait for your EVO to restart

Result:
After modifying the settings for WiMAX, the phone will reconnect to the 4G tower in as little as 20 seconds after being disconnected!
This is a HUGE improvement over the 5+ minutes to reconnect if a loss of signal occurs (300+ seconds).

You can also have it connect with a weaker signal by lowering the Entry_RX to ~ -100-95db and the Entry CINR to 2. Lowering the Exit CNR and increasing the Delay will also make it wait longer before falling back to 3G.

Also, leaving WiMAX (4G) turned on all the time, will normally drain your battery quite fast. After making the change above, it will cause your battery usage to increase because the phone will be checking for service much more often.

Remedy: Turn 4G off when you are not using it.

I could only have entry CINR entry values at 4-10 (wouldn't take 2). Also (nit picky) Max values were 120 vs 300.
Thanks y'all for the mods. I changed everything else.

...adjusting to life without the trackball

Can someone post what the factory setting are for the
"WiMAX_Scan_Retry(s)"
"WiMAX_Entry_Delay(s)"

In case I want to go back. Thanks

Scan = 120
Entry = 300

Can I get default settings for Wimax. Tried the changes but must have changed something unknowingly. Not sure what to change back without defaults listed.
