How to unroot nexus one - Nexus One Q&A, Help & Troubleshooting

Hi my name is David Peniche and I bought from a friend a rooted nexus one but i wanna take it back to unroot because i wanna be able to get all the updates available from google to my cell.
Some body can teach me that please??

The first step is to use the search button
The second step is to read the results
The third step is to read some more as you will probably come across answers to questions you don't even have yet.

I've read everything that I can and I didnt find the answers so that's why I opened this thread because of that issue

So you typed unroot nexus into the search bar and couldn't find the answer? come on.....

Yes you can. Sell the phone and buy new ane unroot one!

And finally, you can post in right section Question > goes to Questions & Answers part of the Nexus forum !

thats right mate and theis fellow put htis in dev instead of q N a
he is right
this is a dev zone go to this link and google
http://forum.xda-developers.com/showthread.php?t=567610
and go to his wiki it will tell you how if you have the g1 from google is is all ready root
wow ! This is a record ! 20 mins and no one has bashed the starter of this thread? Lmao !
Its all good though man.. just read up on ROOT, SPLS and Requirements.. if you read the guide on how to root your phone, you SHOULD be up and running the latest cyanogen mod rom within the next half an hour.. be sure to READ the directions carefully.. and if your not sure about something, scroll through some of the posts in the thread.. 9 xs out of 10 someone has asked your question, and has received an answer... if there are too many pages to read, like let's say maybe 40 or more, jus go to google, and search for your problem.. this site plus some others may pop up and offer you some help.. good luck and welcome to the community !

In my opinion u should defenitly leave ur phone @ STOCK
Cause if u really need a step by step how-to plus you are not "smart enough" to search for your self in this forum and or the web, then i guess you will brick your phone.
Imo rooting mobile devices and/or installing custom Roms / Firmware is something for Users with some experience. And you DONT get this experience with just asking and following a step by step guide ... you have to understand what you are doing!

Nah, I cannot take this comment of you as you state it.

The forum was a bit cleaner and smaller, when I came in, but still with a lot of nice and helpfull guys.
I think a good beginning is to read my noob how to (see signature) and then simply search whatever you need + optimus black in search up in the right corner and you ll get whatever you need

The fastest and easiest way to solve these problems is to read and/or search the thread. Both of these questions have been asked and answered.
For instance if you search that thread for the word "speakerphone" the very first result will give you the answer for the fix and ultimately links to post #125 of that thread.
Similarly if you search "usb" it takes slightly more time, but the 6th result will give you the answer you're looking for. It links to post #133 of the thread.
Please use the search button and read through the thread a little bit before you post questions. Most of the answers can be found in a couple minutes. Good luck with the fixes.
Thanks for the reply, maybe was my mistake, not to say that I have attempted to apply the patch to fix the problem with the microphone when I activate the speaker, but not work for me, so I want to see if I skip any step, and know what i must do step by step, and had also watched the transfer via ssh but although it is a solution, not like me at all.
i flashed asop google edition with safetrap for s4a,i can use data connection in stock rom but not in custom rom,i've tried *#*#4636#*#*,which worked in stock rom,but not in the custom rom,resulting in error request message,can any1 tell me the key words to search the forum for this problem?

No, but we get sick and tired of people asking the same questions over and over again because they are too lazy to actually put the effort in to searching and reading properly
Also, don't 'bump' your own thread within 24 hours - read the rules if you're not sure why.

That's the whole idea of a Q&A.. With every new (original) question the knowledge database grows. This allows other people to just search through the threads to find their answer. It's actually an easier way to find answers then creating a new thread, since you don't have to wait for reactions and usually the follow up questions are already elaborately discussed..
On topic: I believe some superusers have an option to unroot? And otherwise just reflashing stock is just as easy.

Alright then i renamed the thread. Because my question is about walkaround reflashing and unlocking bootloader.
Is it possible simply to root and unroot without reflashing and unlocking ?
When you root phone your root file is on system partition and you need to format it If you want to remove root.Hard reset don't format partition so that won't work.Update software should work but I am not sure.SuperS have ability to remove itself so if you root your phone with it you can done it fastest way.Also don't be smartass and mock people who are telling you to search for answer before posting topic and asking for help.It I is not polite.After all you are asking for help from us not the way around.

on topic: So i am on latest 4.1.2 if i force the support tool (from LG) will it reflash the phone with stock frimware after root ?
As i remember i read somewhere that actually it is possible to use some kind of "upgrade recovery" option with this tool which reflash phone.
off topic: Im not playing it smartass i've searched and couldn't find what i need to know. then i posted this thread.
So maybe someone should check if a thread exist actually without beign too lazy. before saying that he's sick of people.
And also renamed my thread to be more suitable to people who will be searching.

You did NOT search!! Put the word "unroot" into Q&A forum search box and you get 60 hits, at least 5 of which on the first page give the answer.

simon its too late mate... i renamed my thread alredy and i think you did not read that its about walkaound flashing and unlocking.
@tuncay93 in LG update tool should be option "force update" or something like that.BTW I think easiest method is just to flesh.dz file since it will format system partition for sure and you need only drivers that you must install even if you want to update regularly your software.Download SuperSu it should replace your current root app and then from SuperSu choose "remove SuperSu" .That is all I can think off.

Really? Simon is a long time member and he know what he's talking about. He might sound a bit mean sometimes but he's right!
I for myself created like one thread asking a question and the other things I sorted out myself with brief searching, reading and trying.
This question here has been answered already.
You're asking how to unroot without flashing back the stock ROM or unlocking bootloader.
It has been answered in this thread as well and a search (not just on XDA but on Google as well) would've get you to the same answers.
Simon can't tell you where to post and where not but he does as he is trying to get newer or ignorant XDA members to follow the rules.
And one of those rules is to search.
Not just a five minute look but a brief search even in related threads etc.
You won't learn anything by just asking and asking again but by trying and figuring out yourself.
So please do us a favor and stop posting unnecessary questions.
@laufersteppenwolf

I know you're in hospital as far as I remember but maybe you can clean this thread if you get time to do so.

1.By the first few words you said i suspect that you define the pople by their registration date at XDA.
2. I didn't found answer to my question thats why i made thread. [Ans. It is actually possible SuperSu will remove root [not sure what kind of remove but still....[ Flashing with support tool is the way but is still flashing]
3. I am not ignorant and new at XDA. I am new to 4x HD section. Also without reading and asking you can't learn anything. Thats the point of the forum.
4. And i think it was necessary question. Since i've searched and couldn't find what i needed to know.
Finding related threads about "How to root", "How to unroot" all say just unlock reflash and relock. Why ? I've just find out today that i can simply run support tool and all will be fine. (Also mine is 446-92 FW I'm not sure if relockable yet.)
Also that standing behind someone just because he says few words that he has read at "Rules" In wrong place....
And just because its old member it's not cool mate im sorry but thats what i think.
Now if moderators think this is unnecesery thread can remove it.

Ye thats what i find out today theres walkaround for flashing and unlocking bootloader.
In lg support tool click options then upgrade recovery and you are good to go for warranty or whatever you need it for.

Let's get behind this rules etc thing but if you'd read more about root function and flashing a stock firmware you would've know that root is installed in system and that a simple reflash unroots your system.
That's what I mean with reading and understanding the way your modified android device works.
I don't know if it's just me but I did know nearly everything about root before even bothering to root my device just in case if something goes wrong I exactly know what to do.
The answers are out there. Most questions can be solved by searching but many users don't do it or they don't have enough knowledge of Android to understand the given output of their searches.
And no I don't define people by their registration date but by the way they post on XDA.
And I'm not supporting Simon because he has said a few words about rules. I'm supporting him because he's been a long time member and follows the rules.
And sorry but if somebody is criticizing your thread in a forum like XDA and you're responding with "STFU" shows me that you're ignorant and lacking respect.
The fact that Simon is doing this is to keep people from posting 10 threads about the same question (like they tend to do) but search and know what they are doing.
The problem with the community is that most new users just follow tutorials but don't know what to do if something goes wrong (and believe me there always will be something that goes wrong) and then they create threads like "help I bricked my 4X HD".
Like I said if you'd know what rooting actually does inside your device you'd know what to do with information you get when you search for unroot.
Let's assume you are a new user and you now install SuperSU and somehow it messes something up.
What will you do? Do you know enough to mess with an android device? I really don't want you to take it personal but that's the way you should think about it.
And I have one question: Why do you want to unroot your device without reflashing stock firmware and think that unlocking boot loader would be necessary to unroot?
(and just one hint: it's not "walkaround" but workaround what you mean I guess)

Okey I know what Root is. I have been rooting and unlocking all my phones i've used to switch roms. (I know that reflashing is the solution)
But the problem is as i said my 4x HD isn't EUR-XXX it's 446-92 (Asian one i suspect)
So unlocking is possible but couldn't really find info about relocking.
And i was in need of workaround as you said (My english is not good) Because my power button its not responsive and the phone still has warranty and that button its going to brick it keeps going more and more unresponsive.
So i didn't wanted to unlock and reflash because i may void my warranty in that case i still need it.

You don't need to unlock anything in order to reflash the stock firmware with LG Support Tool.
That's what I was talking about. You don't know this because you didn't read enough about this device.
And about your warranty: if you'd search in that topic you may acknowledge that rooting doesn't void your warranty in most places as long as the failure (in your case the power button) isn't related to the slight software modification.

Ye but i know here in my country all warranty providers are just looking for something that may void it and just root will void it i am sure.
But never thought support tool works after rooting or modification on software. i did not even think about searching for that you are right now.
