unroot/relock Sprint phone for TEP replacement...

[Alpine-]

I recently got a replacement authorized through TEP with Sprint. I had previously rooted my EVO with Unrevoked 3. I ran Titanium Backup and backed up all apps/system data. The transition to the new phone went well. I had all apps, settings etc. exactly as I had on the other phone within 15min. I paid for the app because it is THAT worth it. Particularly if you play with a lot of different roms.

My question is this: I'm now wondering if I properly relocked/unrooted before I sent it in. I want to avoid any potential issues if a tech feels the desire to go above and beyond and point out that my phone voided the warranty with a root.

I took the following steps before I sent the phone back:
1) Applied the unrevoked forever S-on tool (by unrevoked, see here: public:forever [RootWiki] If you look at the FAQ for Unrevoked 3 it points you there.

How do I re-enable security on my device?
If you wish to re-enable security on your device, please follow the instructions for S-ON on the unrEVOked forever page.

You end up here...

"How can this be removed or undone if I need to take my phone in for service?
Download the latest ''S-ON'' tool to a temporary location and follow the installation instructions above to run it. Once your phone is S-ON, you may lose root permanently if you install an official update"

So I took this as the Unrevoked Forever S-ON tool worked to renable security if you used either unrevoked 3 or unrevoked foreever (s-OFF). I Applied the S-ON via recovery menu as instructed with no issue. Then;

2) Factory reset the phone. From a dialpad press "##786#" - This will take you to EPST mode with your MSL. Then press your "Menu" key on the phone and select "Reset."

Oddly enough, when I went into apps after resetting to stock rom/configuration, I saw the Super User App (lil ninja guy ). Anyway, I dont recall this being a standard app. Why is it here after resetting? Did it not get unrooted properly? Wont this app being there be a dead give away its been rooted? It's in the mail as we speak.

They almost never used to look to see if the phone was rooted or not, though I have heard that they are starting to crack done on it more. The easiest way to ensure that you are unrooted and there are no tell-tale signs, just reflash the latest stock Sprint ROM. You'll probably be OK though.

That is essentially what I did. This was a stock Sprint rom and I just applied a factory reset - essentially like installing stock RUU. I just did not recall the super user (ninja) app in the apps list before. This made me wonder if it was still rooted. I figured the unrevoked s-ON tool/patch took care of this per the sites instructions. I'm not sure now and this was the first time I tried "unrooting" a phone. I'm a new EVO user.

Your phone is still rooted you just turned S-on back on. Doing a factory reset doesn't unroot your phone it just erases the data. Don't worry about being rooted, if you already have your replacement you must have used Assurion which won't matter if your rooted since it is an insurance claim not a warranty claim.

Just flash the stock ruu zip and call it a day.

I also ran a non-rooted RUU. I was left with a phone like it came out of the box. The only Root evidence was on my card.

Actually, it was a TEP replacement. They sent a refurb and and return kit. I tried to flash the stock RUU.exe via my PC and it kept timing out saying it couldnt make a USB connection. I didnt get it. Finally, I just got fed up and did a factory reset.

So it looks like my first venture into Android re-rooting was a failure. All I did was turn security back on via S-ON tool and reset the stock rom. I guess thats why I still had the super user app in my app list. Lets hope the tech doesnt look too closely.

Whats the next best way to flash an RUU rom when it wont let you do it via USB through the PC? Put the image on SD card, boot into recovery, then flash from there? I could not get the stock RUU to work via USB for some reason. Just gave me a USB connection error afterlike 1 min.

Thanks for your input into my unrootfailblog.
