Will doing a factory reset (hard reset) undo the root on my phone?

[Tastyboi]

I have an old smart phone device.

Sony Ericsson Xperia Arc S LT15i
Android version: 2.3.4

I have rooted the phone and it is working perfectly. Until recently when trying to update Facebook and add a application. Something happened and the phone crashed and wiped a lot of things. Most were just hidden, and managed to find them all. But one app won't get installed. And every time I reboot I get an error message "system uids inconsistent".

I don't want a new phone cause I like the size of the older ones, I don't like the big ones that are out now.

As a last resort I am going to do a factory reset. But my question is, if I do a factory reset will that undo the rooting of the device? And will it revert back to the original Android version or keep the one its still on?

Thanks for any information.

Doing a factory reset won't unroot your phone and it will still be on the same Android version. You'll want to backup anything important since factory reset will wipe/erase your data.

Great, thanks for the info.

Yes, I am knowledgeable enough on how to back p. I have backed up in several places, just in case one or 2 of the back ups bring the problem with it.
