To root: 1 click root. It gives you superuser permissions and also flashes Clockwork recovery so when you press power+vol down, +vol up you can access CWM recovery.
To return everything back to stock (to sell or send back to ASUS): I used NVflash to flash the stock image. It appears that when I press Power+Volume Down, and then Volume up, I get a green android recovery but there's an exclamation mark stating there's no recovery or anything.
Is this normal? How would I change this?
To return everything to the original settings using Roottoolkit or razor (after rooting and flashing a custom ROM), do I unroot and then NVFlash stock rom? Or do I flash stock and then put it in APX mode and unroot?
Just a little confusion.

When I load the bootloader with power and volume up and select recover it gives me the triangle picture with an exclamation mark in the middle. I am unlocked and rooted. I installed clockwork and can get to it from rom manager but not through recovery option. Help please!

i think this is covered in the FAQ, and it's definitely discussed in several threads already.
The triangle is the stock recovery. If you've updated to 2.3.1, the stock recovery is restored by a startup script every time you boot the phone. You can disable this by renaming the file /etc/install-recovery.sh. Then install clockwork again.
If you want to stay on stock recovery, to get into recovery, you do the vol up and power button, then from fastboot select recovery. Watch the screen closely when the phone reboots...for a second or two you'll see a box pouring an arrow onto an android. During that screen push power first (hold it) then push volume up. Timing is important.
Think I rooted it , tried to go into recovery, now I'm stuck. anyone here? right now? maybe can give me live assistance, over IM of some sort? pleaseeeeeeeeee
Looks like you're in the stock recovery, and the clockwork recovery mod was overwritten (it does that every time you reboot).
you can refer to this post for instructions on flashing the cw recovery again and rooting: http://forum.xda-developers.com/showthread.php?t=931865
it's basically just a fastboot command.
What do you mean you think you rooted it

Also someone posted Odin with stock image...perfect for situations like this
http://forum.xda-developers.com/showthread.php?t=947950
i don't think we need to go the Odin way just yet
it sounds like he's in the stock recovery, he just need to do the fastboot, and all that stuff to get things going
The box pouring an arrow onto an android and/or the exclamation mark android is stock recovery. From there, just hit power first, hold it, then hit up arrow, you should get into stock recovery.
If that didn't work, pull the battery and let the phone boot normally. IF you're on 2.3.2 or higher, the install-recovery.sh script will replace the stock recovery in case you some how munged it up.
Reboot into fastboot with the volume key and power key, then when the box with the arrow appears do the power key hold and press the volume up, you should be in stock.
As others said, you can also just fastboot boot or fastboot flash the clockwork recovery image.
You're phone's not bricked, so no panic necessary.
edit: oh, and finally, if you actually succeeded in rooting, you could also just use ROM Mgr app to flash/boot to clockwork recovery, which is what you really should be using.
I am trying to unroot my nexus s. I can't get back into recovery mode at all. I get the android guy and a ! screen. trying over and over still gets me back to this screen...... what to do?
Vol UP and POWER will take you to the bootloader.
fastboot boot clockworkrecovery.img
you should now be in clockwork recovery. It will revert back to stock on reboot, so you will need to mount system and rename the install-recovery.sh to install-recovery.old
I believe it is in the system/etc/
adb reboot bootloader
fastboot flash recovery clockworkrecovery.img (this will replace the stock recovery)
I dont have clockwork recovery on my device..... I kind of need a dumbed down walk though. I tried the unlokr's walkthrough and thats when I found my device won't go into recovery mode. It tries and then goes to the above mentioned screen.
http://forum.xda-developers.com/showthread.php?t=1000722 read through this long thread that I took a user to install Clockwork Recovery (or just look at the stickied thread in General in regards about rooting.. it includes flashing Clockwork)
this 7 page thread is dumbed down to the point where it cannot be dumbed down any more.
If its still stock after you select recovery it will show you the image and then you have to hold even power and volume up again or just volume up I can't remember.

If you can see that android with exclamation mark, i think you are already unrooted.

You are unrooted and completely stock it sounds. If you want Clockwork installed you will have to unlock the bootloader, fastboot OEM unlock, then root or leave it unrooted

yeah, but what if the user cant find the "install-recovery.sh" file? for instance my "etc" folder doesnt have that file and i'm rooted.

then the stock recovery won't keep reinstalling itself and CWR will be default.
When I turn the device on I still have an unlocked bootloader. im trying to re-lock it, and nothing is working
I had trouble going to the recovery menu when trying to manually update to 2.3.3: when you see the android robot with the exclamation sign after selecting recovery, you're supposed to press vol up + power again to access the file selection menu. However, pressing the combination would do nothing for me unless I pressed it like 10 times. Then I would glimpse the recovery menu and the phone rebooted unexpectedly.
After an hour or so of random unwanted reboot cycles, I pulled the battery out, put it back in, tried again the exact same way I had just been trying and it eventually worked.
Don't know if it has anything to do with your issue but maybe it helps?
Actually I figured out how to get into recovery with the exclamation mark and andriod moniker on screen.
Use the vol up and power key and simply press them at the same time and release both immediately.
I cannot get the recovery flash to stick. My phone is rooted and I downloaded ROM Manager and flashed clockworkmod. I pressed boot into recovery and it worked.
I rebooted the phone and then turned it off. I hold power and "x" and it loads the stock recovery with the triangle and exclamation point, I press volume up and camera and it's the stock recovery mode.
I go back into ROM Manager and flash alternate recovery (SPrecovery) and then I turn off phone and boot with "x" and power and it goes into SPRecovery. I then reboot and then turn the phone off and it goes back to stock and I cannot get back into the SPrecovery mode from power off.
Why does it seem like it keeps resetting? Am I doing something wrong? I've tried flashing clockwork about three times and I can only access by pressing the boot into recovery on the app but not from a powered off state.
Why does it do this?
Android 2.2.2 FRG83G stock ROM.
I posted this a week ago and got 0 responses... does no one have any ideas or links you can send my way to help me out?
Should I try and flash an alternative recovery manually and not use Rom Manager? Any tutorials for that?
After I updated my (unrooeted/locked) Nexus S (9023) to 4.0.3 I wanted to try the 4.0.4 upgrade. After the 4.0.3 the recovery mode lost the backlight, so I figured the it was a good time to root.
I tried this one-click script to unlock. It worked and I installed CWMR and flashed the 4.0.4 upgrade. After a reboot the phone had ICS 4.0.4 and got root.
But not all is working. I lost the ability to get into the bootloader by pressing 'vol down.' & 'power'. The phone just starts normally.
The only way I can get into the bootloader, is to "reboot to bootloader" from a command line. If I choose recovery, I get a picture of an android at its back with a red ! (2105.dk/temp/img_1161.jpg). After two minutes it automatically reboots. What has gone wrong? What does it mean? And how can I fix it?
I'm new at this, so i'm out of ideas
try Vol up + power
Ahhh... now i'm feeling a bit stupid
Okay, i'm able to get into the bootloader, but the problem with the recovery still remains. (what does the picture mean? - 2105.dk/temp/img_1161.jpg)
I've tried both CWRM and TWRP. They seems to flash with no errors, but i still can not get them started from the bootloader (fastboot mode?).
Not sure if it's what you are looking for since I can't see the picture you are talking about but I think it's the recovery "security" screen. When you are there press power first and maintain it to press vol up, you should now be into the recovery...
Also remember stock rom has a script that overwrites any custom recovery with stock recovery each time the rom loads.
Yes, pressing [power] + [vol. up] at the recovery "security/error" screen, starts up a recovery.
I also didn't knew that the stock ROM overwrites the recovery. I never seen it mentioned any where else.
Thanks for the hints.
Okay, after learning how the stock OS trying to reinstall stock recovery, I managed to rename /etc/install-recovery.sh to *.bak
Now the stock recovery stays away, and CWM recovery stays on permanent.
Also, the error screen doesn't show up any more. (never found out what it means)
