[1 Click Root] I Have Two Questions...

Ok, i just heard of the one click root app now out for the nexus one.. I always wanted to root, but every time I did, i was never able to get it. So anyways back to my questions...
*[1] I have stock froyo frf91.. I manually updated all the versions leading up to frf91 not once did I receive an ota update... Once I root, will that cancel my ota's? (even tho I manually update them) will I still get an ota update to gingerbread if I root?
*[2] Once I do this root thing, i want the best rom that includes a fast, clean, eye candy, all black theme. (Including the notification bar) after I find this, how do I go about and apply it? How do I install it?.. Isn't there an app in the market where I can look at the newest roms and themes and just apply them from there?
Sorry for the noob questions guys, i just want to witness what all of you have.. I want to unleash the potential of my nexus one! Lol.
** On a side note, i also heard that once you get a cyanogen rom, it is a must that you download the titanium back up app.. is that right?.. because that rom deletes everything...?
Thanks guys, very much!

Never heard bout the Backup thing issue,
But No, once rooted you dont get OTA's (due the fact you change recovery image and rom)
I believe if you still keep things stock like Recovery, and Official ROM you do! (but unsure of this)
Also there is a adb way to root which is simple and thats how i rooted my phone!
you can give that a try instead of one click!
there are no roms in market..
Also try to look through the Dev section, to even apple Dev roms you need to flash custom recovery then do a nandroid back up, then from ther you use the apple from sd!
http://forum.xda-developers.com/showthread.php?t=736271
this is the method i followed
-note if this is gonna be your first time rooting, i suggest you read all info possible bout it, then read it again.. the think on how your going to do it , then reread the info then apply.. while applying stil read the info

woah there. He'll still get the OTA notification and can even download it. You just can't apply the OTA updates. You have to use a rooted one, generally available here before you'll ever even see the OTA notification on your phone.

if you are rooting for the first time do it the loop adb way. Its a bit more involved but once you do it you will learn a bit about adb and other methods that you will need in the future.
One-Click root is going to make the more fun parts of modding harder in the future. The guide in the stickies is very easy to follow and it will pay off in the long run.
Or fastboot oem unlock it and have the badge of honor

That's the thing, i've tried doin it the adb way.. it just never worked for me..
And I also don't want to unlock the bootloader

this way should work like perfect, the other way with pulling sdard way seems kinda over that top for me..

Yea.. so if I use this one click method, i can use custom roms and themes?

Yup, I did that yesturday, there are a few more steps after rooting to get custom roms to work but you can do it.
On another note, cant you just flash back to stock, then using rom manager get rid of the custom recovery, then unroot using the 1click root? Wont that put you back to stock? cant you use the ota's then?

The AndRoot app is awesome. U can turn root ON or OFF anytime (even for ota).

and wear it proudly! fastboot is a cinch and pretty hard to ef up. the worst part is the syntax (especially if you dont have the recovery image in the right directory). i found this link to be helpful in learning how to use fastboot.
i used fastboot to unlock and to flash amon ra. then, running amon ra, i flashed whatever ROM i wanted. later, just for s and giggles i used rom manager to install the clockwork mod recovery.
if you dont like the outcome, you can always flash back to stock which will redo the stock recovery too... but the unlock badge will remain proudly displayed.

How to Flash Clockworkmod Recovery 3.0 easily from your phone

I found a really easy way to flash the new recovery. My fastboot didnt seem to have an option for a terminal so I thought of this genius yet n00b way. Here are the steps.
Steps:
1. Install clockworkmod from market.
2. Flash Clockworkmod recovery from Rom Manager.
3. Navigate to clockworkmod/download/koush.tandtgaming.com/recoveries (or where ever your recovery was downloaded to. This can be done in File Manager, Astro, or Androzip.
4. Mine was "recovery-clockwork-2.5.1.3-vision.img". Rename it to "recovery-clockwork-2.5.1.3-visionXXX.img" or something obviously different.
5. Download clockworkmod 3.0 from hereish:
http://forum.xda-developers.com/showthread.php?t=893933
6. Move your recovery.img to clockworkmod/download/koush.tandtgaming.com/recoveries and name it recovery-clockwork-2.5.1.3-vision.img
7. Go into ROM Manager and Flash Clockworkmod recovery, it will say its still 2.5.1.3 when your done. Reboot into recovery and you'll be welcomed by a new orange 3.0
More than likely i could have done it much easier but it just kinda clicked and i didn't wanna bother with fastboot as it feels clunky on the G2.

there's nothing noob about it. that is a bonafide hack. nice!

I tried something like that but I didnt rename it correctly. So nice to know though. Good work.

How is that a hack? LOL

not really a "hack" per se but it tricks ROM manager into flashing a newer clockwork while still thinking it is the same old one. i thought about doing this the other day but never got around to it so great job on this

Nicely done, flashed it via your method.
You may want to correct the typo you have in there as I first tried to copy and paste your file names. It's clockwork, not cockwork.

For some reason flashing recovery from fastboot hangs everytime on my phone. This way is good but I did it in terminal. I actually had to flash a cyanogen rom to get the fastboot command, this method would have saved that step.

And the downgrade?

fastboot is a lot easier than this IMHO !
You will have fastboot if you have got adb setup on your PC. See the adb guide in this forum for how to setup adb (and fastboot too). It's worth going to the effort, because fastboot will help you with various things in the future. Also you will need the eng hboot.

thank you so much! man now this i can do. i was trying to adb or find terminal in my fastboot.

I'm just starting to install custom ROM tho my DZ, but is this means that ROM Manager will never integrate the new Clockworkmod Recovery?

Thank you kind sir.

Thanks for this simple guide! Before I move forward though, a couple of questions - I need this recovery to flash gingervillain or the CM7 that's being worked on, right? But if I want to revert back to my nandroid backup of cm6.1.1, will I have to flash the old recovery before doing so? Cheers

now cmon stevie, i agree its good to have adb and proper sdk w\ drivers installed. But for the super ober noob thats wants shiny pretty new cw3 for whatever reason be it cm7 or just because, even trying to teach the super ober how to cmd and cd to the sdk is a larger challenge than this. Im just saying your a well respected source of info on xda to a lot of super obers and to say this is easier on the big picture, well thats just crazy talk. This is pretty easy for just about anyone.

semi brick, been awake 27 hours trying to fix please help...i searched extensively

ok heres the situation, i tried to root my wifes mytouch 4g...i have rooted before, so i figured hey wtf lets give it a go, i got clock work 3.0.0.5 installed fine, but i cant get a restore to work or anything form there...i can do clock work and hboot/fastboot...nothing else...cyanogen just causes splash screen free...and so does anything else i flash...now i downloaded pd15img.zip and attempted to use that...but it just fills the blue bar in hboot and says checking pd15img.zip then goes back to hboot main screen i am never asked to load the zip with volume...please ladies and gents i know im not completely done here...and if i am i will get a replacement, but it seems like it should be an easy fix...what am i doing wrong...if i try to reflash recoveries in fastsboot i get signature verify error

http://forum.xda-developers.com/showthread.php?t=944681
this happened to me as well. i went to ice glacier and then followed the instructions on the link

You cannot use 3.0.0.5 for stock. You must flash an older recovery or 3.0.0.6 and then it will work. This is covered extensively and has been asked over and over again.
Flash the correct recovery for the rom you want to use and your problem will be solved.

i tried...
i have loaded other roms...i cant get a single one to make it past the splash screen...i cant flash another recovery from fastboot...i am baffled, you would think if i have fastboot...hboot...and clockwork it owuld be an EASY fix...anyone point me a lil further in the right direction, i dont mean to be dense i been up for a LONG time trying to figure this out, now im at work...slow day...and if i can fix this before i get home my wife will be SO HAPPY..so which version of ice glacier i just tried 1.1

Just flash 3.0. 6 and flash the rom you like, you should be good to go, you can set up web to flash the recovery... hope it goes smoothly =)

i can set up what to flash the recovery? i cant flash through fastboot i get a signiture error, no matter WHAT recovery i use...old...new....05...doesnt matter and im at 05 right now...i know i need 6...i think that owuld fix me to...but i have NOT A CLUE how to obtain a new recovery without being able to move past the splash screen...i can boot into hboot...fastboot...and clockwork...nothing else.

like 20-30-40mins at a time, and it just stays on the splash

If the computer recognizes your device in pretty sure you can set up adb. Thanks flash recovery through there, you should have been able to flash Glacier, you must be doing something wrong, try flashing and stock zip through recover maybe?

lol you're thinking at light speed bro...
i'm not exactly sure of the commands but i know if you've got adb set up you should be able to do it. maybe adb shell?? i have no idea as i'm not a developer.
i'm confused why you couldn't get royal glacier flashed, it shouldn't matter which recovery you have with 2.2 roms. sounds like your phone just doesn't want to comply...

forgive me... as this is much a partial question as it is a suggestion... (coming from WinMo to Android myself) but can't Clockwork Mod be updated FROM Clockworkmod recovery??
I seem to recall that update.zip is the install for the clockworkmod install... and there's an option within clockwork to install update.zip... isn't that correct?
If so... wouldn't you just download the .zip for 3.0.0.6, copy it to the microSD and install it, then install the ROM of choice?

Do you have SDK and working fastboot? That is step one.

Yep
Sent from my Nexus S 4G using XDA App

*note* i did not develop this method entirely i scrapped it together from multiple posts found here on xda. I give credit to those who did the work first. it worked fine for me hopefully it works for you too.
download sdk tools and install
download fastboot drivers and install
both found here
after that, download clockwork recovery
also download superuser files you want eclair/froyo su it works for gingerbread too.
open command prompt and enter the following
Code:
fastboot devices
if it doesn't return your phone in the following line double check that your fastboot drivers are properly installed.
if it does enter the following
Code:
fastboot oem unlock
follow the onscreen prompt on your phone. volume up to "yes" and hit power to confirm
Your phone is now unlocked. next step installing a recovery.
navigate to the folder where the clockwork recovery image is located.
Code:
cd C:\users\#username#\downloads
or wherever the file is on your pc.
then enter the following
Code:
fastboot flash recovery recovery-clockwork-3.0.2.4-crespo.img
you now have a proper recovery installed on your phone you may now vol dn to recovery and hit power to confirm
VERY IMPORTANT
in recovery vol dn to "backup and restore" power to confirm
select Backup and hit power again.
you just created a nandroid backup of your phone if you ever mess it up you can restore it back to when it was stock and problem free
In recovery vol dn to "mounts and storage" power to confirm
then choose "Mount USB storage"
copy the SU zip to the root of your phone's storage
then "Unmount"
then "+++++Go Back+++++"
then "install zip from sdcard"
then "choose zip from sdcard"
Choose su-2.3.6.1-ef-signed.zip
then select "Yes - Install su-2.3.6.1-ef-signed.zip"
Reboot your phone and you should now have a stock rooted phone.

Ty Joe I will do this as soon as I get home

Just remember to make a nandroid backup in clockwork after you're done rooting, so you always have a working setup to fall back on if something should go wrong in the future

i just came from the evo and rooted that phone way before any one click roots where out. Trust me the nexus s is 100 times easier to root than any other phone it's actually pretty quick and easy, i just went into great detail so anyone could be able to follow it hopefully. I think i have seen some 1 click roots for the ns but i never looked into them once i saw how relatively pain free it is to do this way.
i remember having to copy and paste adb commands and spamming them while my phone rebooted. and hopefully... hopefully it would unlock the evo.

just out of curiousity as i wont know until tomorrow, but does gingerbreak work? if so just using the sdk and using adb to push it seems like it would be faster..

Yes there has been success using that. You could i suppose gain root with gingerbreak and then use that to flash clockwork recovery. You would be rooted and able to flash Roms through clockwork. Bootloader would remain locked.

Thanks all. I'll try this later tonight and report back. I've seen a few root methods around here but wanted to make sure it was no different for the ns4g before I actually got into it.
So to confirm one more time Joe's method he posted here should work for the ns4g as well, right?

Make sure you've renamed the /system/etc/install-recovery.sh script (if you haven't already) as well so clockwork isn't overwritten by the stock recovery.

So for you all that are trying to follow joe's steps, they are correct except the download linked in his post will give you the 3.0.0.4 version of Clockwork and you need the one referenced by netarchy (3.0.2.4). All worked as planned after that.

Please be more specific.
What tutorial did you use?
Did you download clockwork recovery?
Do you have the superuser zip?
If you can enable fast boot and fastboot flash recovery you should be able to mount your usb storage in CWM and then install a ROM and the su zip.

i used the one mentioned in addictive tips website (http://www.addictivetips.com/mobile/how-to-root-nexus-s-with-a-single-click-using-superboot/). i basically followed what these guys had mentioned.
since this failed i read that the other option is to go through fastboot > recovery > and clear everything but this did not change anything.
can someone give me a step by step guideline on how to continue. i dont mind going back to the stock 2.3.4 android. i just bought the phone yesterday

Which version do you have? The sprint or t mobile? Check if you can go into fast boot hold down volume up and then powerbutton. If not you may have to Odin it if not. That super one click looks old..

If your ROM flashed incorrectly, it would lead to your phone being in a state where it just shows a GOOGLE with a Padlock; kind of like turning on a computer without an operating system.
You would have to read the instructions on rooting your phone, which involves using fastboot and flash recovery from fastboot (All this is in the rooting guide). Simply reflash the recovery so you boot up back in recovery and try flash the rom again.

The same happened to me, I fixed it buy flashing a stock boot.img

Sounds like you're rooted and have recovery installed, but your OS is hosed.
Flash a ROM.

thanks for the replies guys. i have the adb setup on my laptop. i took it to one of the stores and he said he cant reflash it for some reason. he said he needs to get some software off samsung and it will take him a day. my phone is brand new and i didnt wanna trust him. do u guys think i should use odin? one of my friend has a galaxy s and he said odin should work fine on my phone.

Can you get into the ClockworkMod recovery menu? Turn the phone completely off then hold VolUp and Power until you get into Recovery.
If you get there, you're golden. Just download a ROM (I recommend Deck's) and away you go.

i can get into recovery but it gives me option like wipe everything and i selected that. but when i reboot the phone the same locked screen pops up. anyone from toronto here who i can contact?

Basically with those wipe commands you make the Rom unuseable. You have to flash a new one or apply it via Odin. There are various guides on this forum section. Odin requires less technical knowledge but is a bit more risky then flashing via recovery. Odin and the Roms for that method can be obtained from samfirmware.com. Zipped roms can be found in the development section here.
