Just did this today and verified that it did downgrade the PRL from 60678 to 60676. YOU HAVE TO BE ON A SENSE ROM FOR THIS TO WORK!!!! and you need your MSL! But you can upgrade to CM7 and it keeps the settings!! DONT WIPE BEFORE UPGRADING OR DOING A RECOVERY!! I have tested this on Fresh ROm and doing a recovery of CM7 that I had made. The files you need are here: http://cid-eabe29f3770d8d15.skydrive.live.com/browse.aspx/.Public/PRLs These are the PRL files. http://forum.xda-developers.com/attachment.php?attachmentid=376738&d=1281375059 This is the link to the older pre 2.2 ESPT file that you need. You also need Root explorer. BACKUP Your ASOP ROM or Whatever Rom you are using first!! The older ESPT file does not have some of the other functionalities of the newer one. Not sure what all but the ##DATA# works and the ##PRL# works and that is all I wanted anyways. Save the PRL files you want on your SDcard, not the zip file but the extracted .PRL file or files. Once you are in the Fresh Rom use Root Explorer and find the old ESPT file on your SDcard or where ever you saved it. Copy it and find the espt file on your phone under the system/app folder and overwrite the espt.apk file there (make sure you have root explorer set Mount R/W) once you overwrite it reboot the phone and goto dialpad dial ##PRL# and a box will pop up asking for you pass# (MSL) enter it and you will see update PRL. Long click that and then you can select where you PRL's are and which one to select then hit menu and commit changes, reboot. Verify it and it should be good. If you plan on doing an upgrade to CM7 or some other ASOP rom. What I did was did a backup of my CM7 and just did a recovery of it without wiping anything and checked my PRL on CM7 and it was the one I loaded on the Fresh Rom. Also if you want to do the ##DATA# and change the HTTP PD Proxy port from 8085 to 0 and the HTTP PD Proxy address from pd.vog.sprintpcs.com to 0.0.0.0 then you should do it on the sense rom before going back to the ASOP rom. The reason I changed my PRL back to an older one is. Since I updated my PRL my data speeds went from 1.5mps to .5. Right now at my work 30 miles from my home I am getting 1-1.5 consistently, will post results from my home here later.
