On Device PRL updating (Root required - No PC needed)

[RulingCzar]

To clear confusion:

edit build.prop line ro.build.type=user to ro.build.type=dev, reboot.
Dial ##778# and select PRL, then choose your new PRL from your sd card, commit changes.

Thank you to everyone who made this discovery possible.

I have no idea if there is another thread for 4G LTE PRL updates on device so I am making this one because I hate having to use my computer. None of these programs are mine I'm just gathering the info for someone else to use.

Step one - Download zip from this post [URL="http://forum.xda-developers.com/showpost.php?p=38226436&postcount=803"]LINK[/URL]

Step two - Install in recovery

Step three - Download whatever prl you want and place in on your internal SD card

Step four - Dial ##778# and enter your MSL

Step five - In the tab marked "Modem Settings" change "clear All MRU Entry" to a yes

Step six - under the PRL tab click update PRL and select the one you want after it loads them up, then after clicking ok go back and do the exact same thing again so the radio dial shows its selected. 

Step seven - Commit Changes

Step eight - ????!??!?!PROFIT??!?!?!?!!??!

You linked to a Samsung thread

 

[RulingCzar]

I know it's a samsung thread, but since the installer is for Samsung you'll need to extract the apk to system/app/ and set permissions to 755. Clear cache, reboot, then try it.

Do you notice a difference on the 3g speeds? Can you post a screen shot of a speed test with the PRL you're using

PRL has nothing to do with data speeds
PRL=Preferred Roaming List

It does if you force roaming onto a carrier with better performance.

It won't change your sprint 3G.

Yes it does as some allow for full 3G roaming if it's a corporate prl.

Do you see my PRL I don't get any faster speeds

PRL Series - Acct- Device

25xxx = Residential acct - LTE/800SMR
24xxx = Business acct (some 3G roaming added) - LTE/800SMR
55xxx = Residential acct - worldphone LTE/800SMR
56xxx = Corporate acct (VZW 3G roaming) - worldphone LTE/800SMR
16xxx = Corporate acct (VZW 3G roaming) - LTE/800SMR
11xxx = Corporate acct (VZW 3G roaming) - no LTE/no 800SMR
12xxx = Corporate acct (VZW 3G roaming) - no LTE/low priority 800SMR
60xxx = Residential acct - no LTE/no 800SMR
21xxx = Residential acct - no LTE/low priority 800SMR

Can you clarify what you mean by set permissions to 755? Not sure how to set permissions to "755"

This only works on an HTC rom huh. I'm on Cyanogen Mod and ##778# didn't do anything.

 

[itsachirpthing]

Ok, I have extracted to system/app and set permissions to 755 (rwxr-xr-x). Wiped cache and rebooted, still nothing. What have I missed?

You have to be on a sense rom to use dialer codes.
