How To: Hack the HTC EVO

A Guide On Accessing 3G Networks Without EVDO Coverage From Sprint​

As of Android Froyo 2.2 the stock EPST app no longer contains ##PRL# functionality. In order to fix this, download THIS apk file and use Root Explorer to copy the DL over the EPST in /system/app/ (must be mounted as R/W. Long click the file->Permissions->check all. Then single click the new EPST.apk and install it.

Step 1: Obtain your MSL (Master Subsidy Lock). This can be achieved by calling *2 on the the default android phone application. A Sprint Support Assistant will answer your call - kindly request that they provide you with the Master Subsidy Lock for your phone. If, for whatever reason, the support personnel is unable to complete your request, follow this tutorial by techwerkz to obtain the MSL.

Step 2: Navigate to this tutorial on your EVO phone's default web browser and download the following PRL file: Techknowfile's 00001 epic PRL

If you weren't prompted to download the file and instead see a white web page filled with text jargon on it, press the menu button on your phone and click "save page" as 00001.prl

Alternatively, you may download the zipped version of my PRL file: Techknowfile's zipped 00001 epic PRL

Step 3: Dial ##775#. Enter your MSL into the password box that appears >> hit OK >> tap on the "Update PRL" button. Make sure "All Folders" and "Type: prl files" are selected. You should see the downloaded PRL (00001.prl) on the list; Select the PRL >> Press Menu >> Commit.

If dialing ##775# doesn't reveal the password prompt, please ensure that the EPST.apk file listed at the top of this tutorial has been properly installed.

If you get a 3g connection from this but it keeps dropping, try turning OFF data roaming. Thanks |Jason8|

If for whatever reason you wish to reverse this change, all you have to do is update the PRL through your EVO.

The following will change when the hack is applied:
