    it tells your phone what towers to use. It should increase your signal a bit, especially if you roam much

    If you are on a Sense rooted Rom, then yes it is not an issue, if not then you should not be seeing the PRL update as you need to be on a sense Rom

    Any Sense UI based ROM will have the option to update your Profile and PRL. This includes your stock Android 2.1 with Sense UI ROM and any custom ROM, like Liquid Sense 2.1.

    If you are running a ROM that does not have Sense UI, like AOSP Android 2.3, for example, then you would have to make a Nandroid and restore one of your Sense UI based ROM Nandroids, then update the Profile and PRL. After that, you can restore your Nandroid back to your custom ROM, and all will be well.

    Hey guys...so I'm back into the Android scene. Use to have a G1 with T-Mo,I now have a Sprint HTC Hero running on Revol Wireless here in Ohio. I am very Android Savvy and electronics savvy. What is the latest PRL update? I have checked my phone and it says I'm running PRL 03472. Does Verizon have a better PRL that would work with my Hero or should I stick with the Sprint crap? I AM rooted and running CyanogenMod nightly builds,they work great for me! Can somebody also please put the newest PRL file here for me to download since I'm not up to date on these PRL's. I DO understand what they do but just need to know which is the newest for this phone. Any help is greatly appreciated! I have the same user name over at XDA if you're interested in talking there as well.Thanks for all the help and info guys!

    Seems like this should probably be in the support and troubleshooting area. Moved. :)

    I just installed Zero Hero Sense 3.5 RC 2.5 which is a sense rom, and I don't see the option to update the PRL. Any help?

    I believe that the Zero Hero Sense 3.5 ROM is based off of a GSM ROM, but made to work with your CDMA Sprint HTC Hero. Since it was based off of a GSM ROM, it likely does not contain the code to update the PRL, which is strictly a CDMA action.

    So, in this case you will want to make a Nandroid backup of your current ROM and then restore a Nandroid backup to your stock Android 2.1 with HTC Sense ROM or just flash a clean copy of that ROM. You can then update your PRL and then return to your Zero Hero Sense 3.5 ROM via the Nandroid backup you just made.
