[EVO 4G General] kolosus:
This is the guide. It may be old but the directions are still true and current. This "flashing" is not like flashing a different ROM. Just because you're looking at a guide that's a few months old doesn't mean that it is out dated. Follow the guide and you will have a functioning device.

If you have a Design working then why do you want to try the Evo? Some more information would help. Is the Design a flashed phone? Is it natively a Boost phone?

The replenish can be used as a donor. First thing that you need to do after you connect the device to the computer and cdma ws is send the Samsung (default) password. Then send the MSL. After that you will find that the phone is more cooperative. After every reconnect to the computer you'll have to send those. Otherwise the phone will refuse to communicate with your programs.

Try that and see if you can get through and program your phone correctly.

You can use any rom that is available for your phone. What I'd suggest is put the phone on a sense rom and flash it. Then try out different roms. Most of the current roms are based on AOSP. AOSP do not have the dialer codes that you need to put the phone in diagnostic mode.

After you flash a rom you MAY not have net access. You will definitely not have MMS aka picture messaging. You should have talk and text.

Try and place a call. Check that your phone is still holding the MEID of the donor phone. If you pass those checks then take a look at this post

I usually go with Method 1. Note that the location for JB and KK roms are different. Had me stumped for a bit when I first tried a KK rom.

After the reboot you should have net access (if you didn't before) and you should have native picture messaging. Good luck.

Buying the guide was a dud move. Flashing a phone is still done the same way. The problem with the Prevail is that the file that you got from trying to read the phone is probably not correct. It is probably just a file with the location you're trying to read with the 'access denied' as the result. So file is not valid to be written back to a phone. Try the method that I outlined above for reading Samsung phones. It'll give you better results.

As for the NVM folder. It has the red slash. Meaning no access. I like to think of it as the Ghostbuster circle. Anyway. On the phone in the same place where you find the circle create a folder by the name of "open sesame door" and reboot the phone. For further clarification it should be in the root of the phone and not inside another folder. For idiot proofing, if you can see the Ghostbuster circle and the folder that you created under the same file tree then you're doing good. Reboot the phone and try to access the folder again. The circle will be gone and you'll be able to get into the folder. Not sure what you want to accomplish by it but hey, you wanted access. You got it.

Profile 0 is 466

Profile 1 is 466_1

Profile 2 is 466_2

See a pattern?

PS: Boost only uses 2 profiles (0 and 1). Virgin uses 3 profiles. Etc.
