Its been a while since i rooted a nexus one, i rooted mine back when they came out.
A friend of mine wants me to root his, he is running FRG83, will the old method of fastboot oem unlock, flashing a recovery and then flashing a new rom over still work?
I have been scouring the forums for over an hour now and cant seem to find any information on it, did google disable fastboot oem unlock (thats the impression im getting). The only methods i can find are the rage against the cage methods.
Would it be easier just to use this
hxxp://forum.xda-developers.com/showthread.php?t=803682
which appearently works with FRG83, then have rom manager flash clockwork mod recovery over, then flash over a new rom? Do i still need to unlock the bootloader with this method?
Yes
fastboot oem unlock
fastboot flash recovery whateveryouareusing.img
Then you can flash what ever rom you want from the new recover (I suggest Amon RA)

Hello,
Yesterday i picked up a used nexus one to replace my hd2 with android. (hd2 was way to big and i fell in love with the custom LED colours in yt vids)
The Phone is set up with stock 2.3.4 android.
My Questions are:
1. What's the easiest way to flash a custom ROM like CM7 7.1 RC (i'm a bit confused with all the howto's and wikis because i have 2.3.4)
2. How to get the colours @ the LED trackball working? it's only flashing white when i get a missing text not even when i got a missed call.
thanks in advance
Just root using your favorite rooting guide, then flash clockworkmod recovery. From there its insanely easy to flash cyan, or many other roms even. But clockworkmod is what you want.
I have just recently figured that one out, some of the nice guys here at xda helped me out alot, it will probably be useful for u

Ok since your on 2.3.4 you'll need to do one of two things unlock the bootloader or downgrade.
If you want to unlock the bootloader just google it then do the following download amon ra http://forum.xda-developers.com/showthread.php?t=611829 put it in the same directory as fastboot (you'll know what I mean after you unlock the bootloader), and superuser (eclair froyo version) http://forum.xda-developers.com/showthread.php?t=682828 and put it on your SD card. Then go into cmd and go to the directory where you have fastboot then type "fastboot flash recovery recovery.img" (where recovery.img is the name of the file you downloaded earlier) (btw no quotes) "fastboot boot recovery.img" and flash su with the flash zip from sd card option.
If you want to downgrade check the wiki http://forum.xda-developers.com/wiki/index.php?title=Nexus_One/Guides_%26_Tutorials#Unroot_.2F_Restore_your_Nexus then just root with superonleclick rageagainstthecage method.
thanks for the help
i already unlocked the bootloader and installed Amon_RA recovery but when i want to get in recovery i just get a callsign with an android what do?
Read the Wiki, section "Installing Recovery".
GSM SLCD Nexus One
Hboot 0.35.0017

Locked Bootloader
Somehow I managed to get stuck here, I'm still not sure how. If I had to guess it would be the bootmanager application, although I haven't used it since this morning.
I really would like to keep the bootloader locked if at all possible. The phone was rooted before.
I figured I could just flash a recovery that's signed (hboot signature verification fails on cwm and amon_ra, via fastboot) but I can't for the life of me find one.
In the bootloader, I click on recovery, shows the n1 splashscreen briefly, then sends me to fastboot.
Thanks for the help.
You won't be able to put a custom recovery on there without unlocking the bootloader or reseting your phone. If you are really wanting to keep the bootloader intact, the easiest thing would be to do the PASSIMG method. Have a look in the wiki and it will explain everything to you. Then once you get back into Android, root the phone before it updates to Gingerbread and then install ROM Manager to get your custom recovery back.
I actually just ended up unlocking it and using fastboot to put a new recovery on it. I didn't know about the PASSIMG method. Thanks for your response anyway though.
hi there every one i updated my nexus one to 2.3.6 (GRK39F) from stock 2.3.4 (GRJ22) sorry but i did not read the post for to upgrade and keep root before upgrading to 2.3.6 and now i am suffering and thought it is not a good idea to post a question there so posting here
my problem is when i upgraded 2.3.6 i was rooted and had clockworkmod recovery image and i had a backup from rom manager as well but before upgrade i wiped the partition and cache and after upgrade i dont have SUPER USER permission nor the clockworkmod recovery tried to flash su.zip from sd card but no luck please can anyone help me get my root back pleaseeeee i need help ....
You'll have to passimg back to an earlier version of Froyo, root, restore your backup, and then flash the update and su zip...

Thankyou very much danger-rat really appriciate your help but today was a bit lucky day for me
I tried to flash a recovery image through ADB and then it went well and then flashed the su.zip from sdcard that gave me superuser permission again thanks again for your help
@0mpranav
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.
why mess with 2.3.6 just use oxygen 2.3.7...

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.

Try It & Report Back...
I need help with figuring how to solve my problem. Whenever I try to reboot it boots straight to hboot/fastboot. I can't update my system because of it. Can't unlock because it freezes at the screen where I choose to unlock or not. What should I do??
What have you done to your phone so far?
Have you unlocked your bootloader?
Have you installed TWRP Recovery?
Have you rooted your phone?
Have you flashed any new roms or kernels?
Can you still access your recovery? (TWRP or stock - stock is just black screen with a red triangle in the middle)
Please give a detailed description of the things you have done, the results of each of these things if any, and when your phone started rebooting straight to HBoot.
Also, is your phone the 32 bit US model, or the 64 bit Europian/Australian model?
There's still a chance your device's firmware is recoverable, but you probably shouldn't try anything until you get some advice from someone who has a lot of knowledge and a detailed description of how you ended up where you're at.
Good luck!
What have you done to your phone so far? I have unlocked it before, but end up re-locking it after failing to root it.
Have you unlocked your bootloader? I did and relocked it.
Have you installed TWRP Recovery? Couldn't and Can't
Have you rooted your phone? No
Have you flashed any new roms or kernels? No
Can you still access your recovery? (TWRP or stock - stock is just black screen with a red triangle in the middle) I can't enter recovery.
I have no .img files when entering hboot. I can't unlock because it freezes after choosing the unlock option. It shows entering recovery at the stop and a discalimer message at the botto and goes no where
How to fix the issue
The first thing is to do is to relock the boot loader by typing 'fastboot oem lock' and the appropriate RUU for your device and carrier and open the RUU and reflash the device and it will be good as new

You should not just lock the boot loader without first reinstalling the stock recovery! When you go to use the RUU if it doesn't see the stock recovery it's going to fail... First reinstall the stock recovery and then OEM lock then you can use the RUU!
P.S. I have no idea why you're replying to some post from 2014... This post was almost a year ago lmao...
You don't have to have stock recover I did it with TWRP Recovery and it put stock recovery for you
