Trouble with Unroot Guide

I'm on the rooted stock ROM currently. I've been trying to follow this guide:

http://androidforums.com/evo-v-4g-a...evo-v-4g-ruu-flashing-guide-unroot-guide.html

I've gotten the boot loader to say "RELOCKED" at the top, but that's as far as I can get. I run the RUU in the link and I get to the point where it says "Upgrade" the ROM version.

I hit the upgrade button and it comes back with:

From: Image Version 2.95.652.5

To: Image Version 1.13.652.2

Obviously this is a downgrade, is that possible or do I have to find an updated RUU?

I don't seem to have a custom recovery installed, so I can't manullay flash the zip from the RUU... what steps should I take to get this back to fully stock?

Thanks!

edit:

Just ran the RUU again and it tries to run but then finishes with:

Error [140] BOOTLOADER VERSION ERROR

edit 2:

Okay, so I re-unlocked my bootloader, flashed a recovery that works and then flashed a file I found called "SetMainVerionLOW.zip" that changed image version to 1.0.000.0. Ran the RUU again and it had slightly different results, but still ended up not working.

Now I believe it says my Hboot is the wrong version.

For now I'm giving up and restoring my Titanium Backup, but I'd still love any help.

Basically what I'm trying to do is go back to a completely stock phone. The reason is that I'm nto getting voicemail notifications and have tried a number of things with Virgin Mobile support. Now they want me to restore the phone and see if that helps.

 

Ah, thank you both. I did the wire trick to get s-off on my original phone, but haven't yet on the replacement. I'll do it another time.

Brian, you mentioned that the best I can do is flash a stock based rom. Does that mean I need s-off as well or can I do it now?

 

Great. So would this then let me perform the built in system restore on the phone? I've heard you shouldn't do the restore if you're rooted.

 

Hmm, okay. So I have my bootloader unlocked... can I flash a stock recovery and then do the system restore? If so, what are the steps to take.

Right now I have the bootloader unlocked, and a stock ROM that's rooted. I want to go back to fully unrooted, stock ROM.

 

See, the thing is tho, I'm having issues with my voicemail.

I had an Evo V, it was working great, then the headset jack died. I got a replacement through the warranty and now the new phone doesn't get voicemail notifications. I can dial in and check them manually, but it's a pain not just getting a notification.

I've talked to support a number of times and they've "reset" my voicemail, whatever that means. Nothing has worked.

So now I'm trying to do a system restore to see if it's something that's messed up on the software side of things (although I doubt it) before I ask for yet another replacement... although at this point my warranty may be nearly up if it's not already.

 

Correct me if I'm wrong, but don't you ened to root before you can do a nandroid backup?

And yeah, I'm going to do the wire trick at some point, I'm just a bit frustrated right now to try it. I'm more or less looking for info at the moment.

 

Okay, thanks a ton... I'll do the wire trick tomorrow or some other time when I'm not burnt out.

I love tinkering with my devices, but it frustrates the crap out of me when things don't go smoothly.

edit:

Any reason why you suggest Harmonia over anything else?

edit2:

I just noticed the Harmonia link says I don't need S-Off... should I do it anyway? I didn't have any trouble doing it with my first phone, so it's not a big deal. Just wondering. Thanks!

 

Awesome, that sounds right up my alley. I'll give it a shot today if I get the time.

Thanks again!
