[Q] How do I put a rooted and ROM'd Eris back to factory

---

First of all, let me apologize if this is already posted somewhere, but I'm having trouble understanding some of this.

I rooted my gf's Droid Eris and put a custom ROM on it. She doesn't want it and wants it put back exactly like it was when she got it from Verizon. This means 1) not rooted 2) Android 2.1 w/ Sense (the exact same ROM she would get from the factory).

Everything I've read so far has me doing factory resets (which puts it back to the fresh modded ROM but not the factory ROM) or has me trying to do RSD Lite, but every forum post I read has a broken link to the file because I guess it's illegal to post it or something. Additionally, I can't find instructions for following that method with the Eris anyways.

Can anyone help point me in the right direction?

btw, I'm new to rooting so treat me like a n00b...

I did a nand restore back to the when I originally rooted the phone. It now has 2.1 with HTC but the phone is still rooted.

Also, when I rooted the phone, whatever it did to root it (put something custom on my phone) it turned the trackball light on and that just won't turn off... even when the phone is off!

I'd love to just get this thing back to how it came from the factory.

Maybe if you try searching the Developement Forum, try something like "return to factory stock"

And in the future before you do anything to a phone, you might want to research how to undo it first, I bricked my first eris because I didn't bother to.

Sure. It's pretty simple, really. Download and install the Flashback21 ROM in this thread: http://forum.xda-developers.com/showthread.php?t=792026

It will return the Eris to factory stock and remove the custom recovery on the phone. I'd do the one without the radio myself.

A friend told me that there is a way to set a phone back to how it came from the factory by installing a factory ROM directly from Verizon through your PC using an app called ODIN. I'm having trouble finding information for the Eris on this process.

I think this is EXACTLY what I was looking for! Thanks so much!



I'll let you know if it fixes that trackball issue for anyone else who may have searched that issue

This did work! I noticed that the ROM wasn't exactly like what comes with the phone when we received it from Verizon (which was the same day). I am basing this off the type of wizard that opens when you first turn on the device. It wasn't rooted, though, and did put back what appears to be a stock ROM of 2.1. It's going back to HTC/Verizon tomorrow.

There are no customizations in this ROM - period.

The "stock" setup screens certainly changed between 1.5 and 2.1, and may have changed slightly from the original HTC/VZW 2.1 OTA to the July 2010 2.1 OTA update.

Having said that, there is one other thing that you might have noticed: you didn't see a device activation screen during setup. That is because NONE of the dev ROMs here on the XDA Eris touch the activation state of the phone - including Flashback21.

If you want to deactivate your phone, you need to perform the Factory Reset process from the OS menu, and a "stock" Eris recovery must be on the phone. (So, if you desire to do so, go ahead and do a Factory Reset after you have installed Flashback21)

If you have already turned in your phone, then no worries - the carrier usually deactivates the phone from their side.

Anyways, that's probably what you noticed. Flashback21 is completely stock.
