is it possible to root donut build once uve installed the real one? it keep aborting any installations i try to do, and doesnt let me flash the recovery img either. i dont know what to do.
Yea the official update will do that... but all is not lost. You can follow the guide here and downgrade to RC29 to gain root
http://forum.xda-developers.com/showthread.php?t=442480
you can follow those steps to regain root on your phone, when choosing which rom you'd like to run, if you'd still like to have root access but prefer the official builds you can check out this thread

if you still have an engineering or death spl, you can just flash recovery from fastboot.
Boot your phone while holding the camera, then press back button, you should see "fastboot usb" on the screen. Download amon_ra's recovery (look for it in android development) and flash it doing "fastboot flash recovery recovery-RA-dream-v1.2.2.img". After it's done you should have recovery back and now you can restore your nandroid or flash another update.zip
I downgraded back to RC29 successfully, but now its not letting me install any apps from the sdcard or online to the phone, it just keeps saying Install unsucccessful on any app. Wat could be causing this?
i ended up rooting the phone the old way, using telnet. now its working again

Now I can't install any rom...
I can tell you what you should've done. Post your questions in the Q&A section. Also if you flashed this because you wanted the newest CM then you didn't follow the directions correctly and now you lost root congrats.
question and answer section is where this belongs....and i don't know what you were trying to do but you need to re read the instructions to do so......
You cannot install any rom because you have loose your root as when flashing HTC Recovery Image 1.6 only you will lose root. So you need to root again before installing any other rom
Before we can help you, we need to know what exactly you flashed, and how you flashed it. I am assuming that you downloaded the ADP1 images of 1.6 from HTC's site. Here are a few questions that will help others guide you to an answer:
Did you download the package to be used through the recovery tool (booting with HOME+POWER) or through the fastboot tool (booting into the SPL with CAMERA+POWER)?
If you used the fastboot method, did you follow HTC's directions and flash all of their images, or did you manually flash each partition?
If you manually flashed the partitions, did you also flash over the recovery image?
Because of the way that HTC limited their ROM, if you did not retain your recovery partition, you will most likely need to start from scratch. (If you flashed HTC's ROM using recovery mode by booting with HOME+POWER held down, or if you used the fastboot method, but did not manually flash the partitions preserving your existing recovery partition, then you need to start from scratch.) Thankfully, it is now easier than ever to do this. Here are the steps you need to perform:
Download RC29 image (DREAIMG.NBH). You can find links to this file on the forum.
Download cyanogen's recovery image (1.4).
Copy both the DREAIMG.NBH file and the cm-recovery-1.4.img file to the root of your SD card. You can do this easily by mounting the SD card, and just copying it over from your computer.
Boot into your phone's SPL by starting up while holding both CAMERA+POWER.
When the SPL finds the DREAIMG.NBH file on your SD card, it will automatically prompt you to install the image. Follow the prompts. This will leave your phone with the first shipped version of Android (1.0).
After the install has finished, reboot the phone by pressing CALL+MENU+POWER at the same time. This will boot you into an old version of Android.
In order to proceed any further, you must re-register your phone. Just enter you Google Account information once the phone is booted.
Change your phone's settings to allow you install non-Market applications. Do this by going to Settings > Applications > Unknown sources.
Open the Browser application, and navigate to http://code.google.com/p/flashrec/. From there, download the current version of flashrec.
Lauch flashrec. First you must backup your current recovery image. Then, tell it to flash "/sdcard/cm-recovery-1.4.img".
Now you have a recovery partition that will allow you to flash any image you want—problem solved.
However, please remember this is development forum, and not the Q&A. Please do post your questions in the Q&A forum. Also, please use the search function, as this type of question has been answer MANY times before.

Oh~ thank you very much.
I'm in this situation because I'm not using the CM recovery 1.4 and I flashed the HTC recovery image 1.6.
I've rerooted my phone.
Hi guys. I don't really know what happened here. I've flashed a few different versions of Cyanogen's builds onto my MT3G without any problems. Today I flashed the official 1.6 dev build of Donut before doing Cyanogen's 4.2.3.1 flash. Well, the 1.6 seemed to go smoothly, but after the reboot, the recovery would no longer load. It's now giving me a picture of the phone with an exclamation point when I try to load the recovery.
How can I fix this? Anyone? Please?
taken from cyanogens website site instructions.
If you boot the 1.6 image it will install the HTC stock recovery. Booting back to recovery will show the /!\[] symbol. THIS IS NOT LOSING ROOT. You can still flash update.zip files from this recovery. Also, you can still flash a nicer (CM-1.4) recovery with fastboot, or flash_image inside the CM install once you get it installed.
thats what sounds like happen to me
How do I do anything though? I don't have the ability to do anything, it just sits there on that screen.
<edit> Also, I can't re-flash the recovery. I've tried, but it gives me the error:
Flash FAILED: The command could not be run
After figuring out how to install ADB and trying to fix it via that, it appears that I have somehow lost root. It's giving me Permission Denied or remote device not allow when I try to flash or use fastboot.
Got it fixed. Took me forever, but I made a goldcard and flashed with the stock ROM. Now I'm good to go again after installing CM recovery 1.4.
I tried upgrading from 4.1.1.1.1. to Cyan's most recent ROM and have locked my phone to ADP1 1.6 do to my phone giving some error and rebooting when it wasn't supposed to. I cannot install Any update.Zip files it gives me the following error (Install aborted) after trying flash any update.zip, i am at stock recovery, and i get permission denied on various commands Via ADB but it tells me i have root still. On top of that Fast boot isn't letting me install any type of recovery image giving me an error (cannot load "cm-recovery-1.4.img"). Can anyone help me out of this funk i am in and again i am not able to unroot my phone to stock. Thanks for the help in advance

ADP1 1.6 ROM(dream_devphone-userdebug 1.6 DRC83 14721 testkeys)
After you flashed the ADP1 1.6 did you reboot the phone or did you flash the cyan rom? I don't actually know what happens if you reboot before flashing the cyan rom but apparently it's not a good idea since the wiki guide says, in bold, not to reboot until after you flashed the new rom.
Well yes i was aware that i wasnt supposed to reboot but as the phone was doing something to the radio it went black next thing i know the phone goes through its normal process to boot up. But this was while i was trying to install 4.2.3.1.
The answer you seek kinda sucks, but it also has a very clear solution: you lost root.
Your fix: re-root and follow the direct instructions for getting to 4.2.3.1.
I dont know why but it seems like im the only person in the world who cant get his phone to work properly.
I rooted, got amonra recovery 1.7.0, partitioned ext2/swap/fat32, flashed newest radio, then flashed dangerspl.
And any rom I flash will never boot past the G1 logo screen.
I have only gotten jesusfreke's 1.5v2 rom to flash. it was the first rom i tried.
i rooted by doing the guide in "forum.xda-developers.com/showthread.php?t=548924", which asks me to go to g1upgrade.com and install root.apk, then use the telnetd method, and then protect root. to confirm i have root, when i go into terminal emulator, and use su root, it asks me if i want to allow application to run as root:root.
any attempt at getting a logcat using adb just says /sbin/sh: logcat not found.
it seems like everything i do always ends in an error noone understands.
can someone please help me before i give up on android forever?

No need to flash the system partition, no need to use ADB, just flash Superboot:

If your bootloader is unlocked all you have to do is reboot into fastboot mode. Flash a custom recovery such as RA or CWM, reboot directly into revovery and flash su.zip or whatever flash zip you used to root your device before. Reboot and you are rooted once again.
The following thread has a step by step how to do it. It's fast and easy.

Yup. This is the way every one should be doing it. It's sort of the whole point of the Nexus One. It has an unlockable bootloader.

I have purchased two second hand Nexus Ones. The first thing I did after receiving them and charging the battery was to reboot into fastboot mode and issue "fastboot oem unlock" command. Since they were purchased second hadn I didn't thing I had a warranty anyway so unlocking the bootloader seemed to be a non brainer.

Will any version of su.zip, and fastbook.zip work? What about recovery-RA-passion-v2.2.1.img? or should we be using a different version?
If we should be using different versions of those, could you link to where we could get them?
I've had my Nexus one half-rooted since 2.3 came out, and I haven't been able to root it back.

I'm sorry I have no idea what that is. I don't even know if its helpful at all. Again, I don't even have root, or a custom recovery. Presently, I have an unlocked bootloader, ADB on my PC, and a half-rooted nexus one from before 2.3.
I have absolutely no idea how to do anything presently, and when someone tells me that trying to root on 2.3.6 is futile and to just use a custom update, it doesn't make any more sense to me.
Care to elaborate past one line that doesn't help at all? Hell when using shell commands through adb, it keeps on saying "permission denied" any time I type in su.
You have an unlocked bootloader, so flash a custom recovery via fastboot, and use the custom recovery to flash the su zip...

Thanks Danger-rat. Although I know you said nothing different that what was already said in this thread, I figured that since you didn't give me specific info about whether or not there were multiple versions of su.zip or fastboot.zip, I figured I should take that as a "No.", so I went for it. All re-rooted now.
I appreciate the help.
EDIT: So if you are as new to this stuff as I am, anyone else who's reading-
You can DL su.zip from http://www.google.com/url?sa=t&sour...ZxOuf9Kw_URvtvh9Q&sig2=Hj72LDNoiBq2Zoa4QquZWQ
and fastboot.zip from http://www.mediafire.com/?ttdkgamud3j
and amon Ra 2.2.1 from http://files.androidspin.com/downloads.php?dir=amon_ra/RECOVERY/&file=recovery-RA-passion-v2.2.1.img
then follow the directions here: http://forum.xda-developers.com/showthread.php?t=1019759
** Note: again, these are for people who have unlocked bootloaders. For that info, you'll have to go elsewhere, but it should be readily available, such as this stuff is. I'm just linking it again because I know how frustrating it can be for people like me who aren't too well versed in rooting/unlocking yet.
Downgrade 2.3.6 to 2.2.2 - Nexus One
Problem:
I would like to downgrade my Nexus One to 2.2.2, because I've had non-stop problems with Gingerbread.
So I've gone through the Bootloader -> Recovery -> apply sdcard:update.zip steps, and it fails. This begs the question, how do I go from 2.3.6 to 2.2.2?
Fix:
Generally, phone manufacturers will not allow you to downgrade for various reasons. The stock recovery does indeed validate the update image, so that it's of a greater (or same) version than the installed system. With the Nexus One being a developer phone, you can unlock the bootloader and replace the recovery image with the one that doesn't perform this check, and will allow installation of any image. The caveat is that unlocking the bootloader voids your warranty with the carrier (and sometimes the manufacturer too,) and wipes all user data off the device.
Unlocking the N1 is dead easy. Just install Android SDK and the USB drivers (located in "google-usb_driver" directory.) Then restart the phone in bootloader mode by shutting it off and powering on while holding down the trackball, hook it up to the computer via USB, and in command prompt issue the following command: C:\<path to Android SDK>\tools\fastboot oem unlock. You will be presented with a confirmation screen with further instructions. Upon successful unlock, you can flash a custom recovery that will allow you to install any custom ROM, including downgrade to 2.2.x stock version of Android OS.
To flash ClockworkMod recovery, download the latest version for Nexus One from here, reboot into bootloader mode (power on while holding the trackball down,) and in command prompt issue command C:\<path to ANdroid SDK>\tools\fastboot flash recovery C:\<path to downloaded img>\recovery-clockwork-3.0.0.5-passion.img
Reboot to bootloader mode again, and then use the Volume keys to highlight the "Recovery" option and press Power button. You are now in ClockworkMod recovery, and can flash any custom ROMs via the "Install zip from sdcard" option.
Here is a "stock" 2.2.2 ROM (with root) off XDA-developers forum.
