Writing custom PRLs...

    Another usefull tidbit of information. CDMA Workshop/QPST don't seem to work this phone. So I had to figure out how to use a Sprint PRL on my Boost phone.

    I discovered an alternate way for this phone that turned out to be easier then using CDMA Workshop or QPST. :D

    First off find the prl you want to use. In this case I used the latest Sprint PRL. Put it on your SD card. (root directory would be best). Make sure it has a PRL extension. If not, then you may not have a valid PRL. The PRL files normally used with CDMA Workshop and QPST can be used with this method so they should already have the PRL extension. ;)


    Second use this dialer code to access a hidden menu:

    ##775#

    It will prompt you for your MSL. Enter your MSL (you must know your MSL to do this). You will be presented with a menu that displays "Update PRL".

    Press it to expand it.

    Assuming you have a correct PRL file, it should display it somewhere in the middle of the screen. Select it, then hit ok.

    Above the "Update PRL" menu option there is small text in the top right corner that says "MENU" in all caps. Press it and commit changes.

    The phone should reboot and your PRL should be updated.

    Voila! Custom PRL on your HTC Design 4G. Should work with other HTC phones as well, but only tested it on this one. :D

    To reset back to the stock PRL, simply update your PRL in the About Phone menu.

    Looks like someone posted a collection of Sprint PRLs.

    http://androidforums.com/galaxy-prevail-all-things-root/540260-faster-prls-3.html#post4424380

    I would recommend the 60687 one as that is one that most Sprint users are on. If your on a Boost phone that is. Using Sprint PRLs on a Sprint phone probably won't net you a big difference in performance. But some of the ones like 11114 for example may be for corporate users and may have access to better towers. If there are better towers in your area that is.

    I've noticed better signal when using the 60687 prl on my Boost phone. Only on 3G though. I think 4G uses something else.

    I got mine by viewing the activation instructions boost gave me when I switched to this phone.

    If the adb trick doesn't work you'll have to try the alogcat method.

    this app works great... very easy... must be rooted

    this is only way that I know how to do this. I have tried this rooted and unrooted and it gave me access to that menu.
     
  10. I'm assuming it is because I'm running the updated leak ROM from sdx. I'm with sprint so I'm just waiting for an official release.

    Try ##3282# this the one that works for me stock or custom rom... Sorry but that one won't let you change your prl.. ##775# doesn't work, again so does any one know the code for stock rooted sprint design..

    PRLs do not get changed when flashing roms in CWM. What you could do is run a CWM backup of your phone, then flash EvilKingdom or another Boost rom using CWM. Then do the secret code which should then work correctly. Then you can change your PRL. Once you have a PRL you like, simply run CWM to restore your backup to get back to the correct rom. ;)

    Well I have to sprint design. I switched bact to full stock because my phone will not update the prl period.. My wife EVO 4G has the current 60187 prl.. Now all I get is a error code of 1233. Will have to call sprint in the morning to figure this one out..

    That's weird it's a sprint/boost prl from another phone. I use to only get 1 bar at my place now I get 3 most of the time. But sometimes it's fickle.

    I didn't know that it had 4G that's something I didn't know about it never tried it because I usually use jb and 4g doesn't work on the cm10. Lol. I'm in Pembroke just below concord. But I'm a little out of the way

    ##775# does absolutely nothing running the new update. ##3282# opens up epst settings, however, there is no option to change PRL. Does anyone have any tips?
