[Solved] Flash EVO back to Sprint from Cricket/MetroPCS!

---

My roommate bought an EVO 4G off Craigslist that was pre-flashed to MetroPCS. It had a clean ESN, so I tried to have it activated. I finally got voice and text to work, but no data. After searching the web, visiting flashing stores, and spending hours on the phone with Sprint's so called "Technical Support" over the last week, I finally figured it out...

This is my first tutorial, so bare with me. And I apologize if this is in the wrong forum, it seemed most appropriate. I performed all this in Windows 7 x64.

First you need some software-
1. QPST - http://www.mediafire.com/?m4s81a4zsdbmhen
2. HTC Diag phone drivers - http://www.mediafire.com/?631456zwxi09hh2
3. PRL File 60650 - http://www.corolada.com/prl/
4. I'm not sure if you need ADB installed, but I already did.
5. You will also need to know your MSL. It will most likely be 000000 if your phone is coming from Cricket or MetroPCS.

Now that we have those, we can get to work.
6. Connect your phone via USB and type in ##3424#, your phone should now be in Diag mode. Make sure USB Debugging is ENABLED!
7. Open your device manager in Windows and right click the unknown device "HTC DIAG", Select Update driver.
8. Select Browse my computer for driver. Click select device from list, Click next, Then click "Have Disk" and point to the appropriate HTC Diag driver folder you downloaded.
9. You now should have HTC Modem installed correctly. Right click on it and go to Properties, Then click on the modem tab. Find your port number eg. COM1, COM2, etc.
10. Open up QPST Configuration, Click the PORTS tab. On the bottom right click add port. Add the port you just found from the step above, and hit Enable.
11. Go back to the active phones tab, double click your phone.
12. On the bottom click read from phone. Then save it for a backup.
13. Click on Roaming tab. Find the PRL box, click browse and add your 60650 PRL file you downloaded.
14. Go back to the CDMA tab. Under phone number click the Class 1 box. Enter your phone number (xxx-xxx-xxxx) minus dashes in the box next to Class 1.
15. Click write to phone. Hard parts over!

16. Once that finishes, unplug and reboot your phone.
17. Go to Settings>Update Software>Update PRL then reboot again.
17. Once its back up go into your dialer. Punch in ##3282#. Hit Edit Mode. The password is your MSL.
18. Once in goto Data Profile. Hit Menu then hit RESET.
19. Your phone should now reboot and be able to activate on Sprints network!


I already did this for my roommate, so I am writing this out of memory. I wanted to post pictures but I would have to take CM7 off my phone and redo all of it... grrrr.
Again, this is my first guide so i might have missed something. But I hope not. So many people have helped me here on XDA, so this is my contribution to the community. I hope this helps some people.

I did this to a hero. I believe I just cleared all the ##data stuff and pep update manually.

I tried that to. But the only way to make it work was to flash the new PRL file. Neither Sprint or a Cricket flashing place could fix it. Which I thought was pretty stupid.

Another quick way of doing it.
Load Stock RUU.
This will rewrite PRL, NV items etc back as it rewrites the radio wich controls these.

Once done ##RTN# need MSL to use this, but this will help as well. and your done.

This is handy to have, and even better to have a few different ways to do it.

I tried this like 4 times, and it would never flash the PRL... the way I did it, it finally flashed sprints PRL.

Go into your phone settings, goto About Phone, what is the PRL number listed?

i am pretty sure i flashed the "60650.prl"
however i sold the phone and it will be back here tomorrow for repairs....

i had the guy do the settings -> update prl without luck....

sigh thanks for any help!
