I tried and it's not working.
Try it. SuperOneClick is not working on 2.3.3
Gingerbreak.apk v1.2 is working on 2.3.3 but not 2.3.4
Gingerbreak isn't working for 2.3.4, any alternate solutions?

I tried SuperOneClick (2.3.4) without succes. How do you root yours?
Kind regards, Lasse
Ok well to root you'll need to either unlock the bootloader or passimg back to frg33. If you passimg back then you can root with superoneclick if you unlock the bootloader then ask me and I will give you some instructions on how to do it.
1. Unlock the bootloader.
2. Flash custom recovery.
3. Flash su or a rooted rom.
If you can't or don't want to do this sell your phone. You should not have a dev/GED period.
not working on 2.3.4. why not flashing a rooted rom? not difficult.

Well it's cause if you want to flash a rooted ROM you'll need to have root access and if he had root access he would not need superoneclick.

[Q] can you install clockworkmod after updating to 2.3.4?

i had a nexus one and was able to unlock the bootloader but i think i updated it to 2.3.4 and then tried to install CWM, which didn't work. i then discovered the antenna was not working correctly so i had to exchange the phone for another new one. once i get my new nexus one i was still thinking about installing CM7 and i just want to get some things straight about 2.3.4 and installing clockworkmod recovery.
will i be able to install CWM after i update my nexus one to stock 2.3.4? if not what is the highest stock build i would be able to do it with?
concerning the radio, if it is not possible to update to 2.3.4 and then install CWM i guess i'd have to update the radio by itself right?
You can unlock the bootloader and install cwm, or you can revert to an earlier version of Android, root, and then install cwm...
so i guess it's not possible to root and install CWM on 2.3.4? what's the latest version of android i would have to revert to for rooting and installing CWM?
There is no exploit for 2.3.4, so there is no easy root...
To downgrade, you have to do the passimg with a shipped image, and the most recent is FRG33. However, once rooted you can update all the way to 2.3.4 and keep root, if you do things in the right order...
You could also update to 2.3.3 and root and update to 2.3.4 keeping root - but the end result is the same...
You can also root 2.3.4 after unlocking the bootloader and flashing a custom recovery. From there, you would need to flash one of the su.zip files floating around (you may need a specific one for Gingerbread), which should remove the stock recovery checks (what replaces the custom recovery when you boot a stock install) and should add the necessary files for root access.
the first nexus one i received was on 2.2.1 so i guess if i plan on installing CM7 i should just keep in there and not bother upgrading anything (maybe the radio only)? just want to make sure where i stand so someone could help me accomplish these things. i know how to unlock the bootloader and i think i'll be fine installing CWM so what order should i:
unlock the bootloader
upgrade the radio (i guess i don't have to do this if i upgrade to 2.3.4)
install CWM
root
upgrade to 2.3.4
install CM7
i'm just making sure i know what i'm doing before i get my replacement nexus one and while i have attempted searching for answers i haven't been able to find the specific order or answer to my question. if anyone can correct any mistakes or assumptions i've been making please let me know.
If you are unlocking the bootloader, there is no need to root the current android install. The whole point of rooting the phone is so you can get the custom recovery on there so you can load CM on the phone. Since you are unlocking the bootloader, you can load the custom recovery using fastboot, then boot into it, wipe the phone and flash CM (and gapps).
And if it is a replacement, it will most likely be running the 5.08 radio, which seems to be the best one for Gingerbread.
So it would be:
Unlock bootloader
flash clockworkmod
boot clockworkmod (select the bootloader screen and then recovery, don't reboot)
wipe phone
flash CM and gapps
reboot

You don't need to upgrade to 2.3.4 unless you want to upgrade the radio and hboot. Of course, you can upgrade them without updating the OS, though upgrading them with OS will be safer.
ok, now that i know that installing CM7 will root my phone if i do it by unlocking the bootloader and installing CWM i am wondering if my phone will be rooted once i restore my nandroid backup that i will make (of stock 2.3.4 android) right before i install CM7?
No. Root is separate from unlocking your bootloader and whatever recovery you are running. Root is at the OS level. Most custom firmwares come pre-rooted. That is, they contain the software needed to allow you to escalate your priveledges to root level. Stock firmwares, do not have this additional software, and anytime you get an update for stock, it will replace everything you had with your previous install, which will make you lose root if you had it.
So, if you install CM7, it will be rooted, but if you restore your stock 2.3.4, it will become unrooted (because it was unrooted when you made the backup).
What is your final plan for software on the phone? Stock 2.3.4, stock 2.3.4 with root, CM7? What is the point of restoring your nandroid of 2.3.4?

[Q] How to unroot phone with stock ROM V20l

Hi Guys,
I am now on stock ROM V20L and successfully rooted thanks to TrymHansen's guide from this forum. I remember that on Froyo you can easly unroot phone in one click with SuperOneClick tool. How to do it on Gingerbread? Just uninstall Superuser or something more? I am asking this in case of warranty issues...
Cheers
As far as I know, you can still easily unroot with SuperOneClick.
