Yes you need to load the shipping rom passionsomething.imgsomething file. There's a thread on it. It's real easy, download it, rename it to a special bootloader recognized file, reboot, go into bootloader and it AUTOMagically, loads it.
No. If you aren't rooted you can't go back. The stock recovery will not let you downgrade.
Unless... I may have heard about one special leaked rom that let you do that, but I couldn't even begin to point you in the right direction.
o i c okay thanks...
anyoine out there know if i can update my non rooted 2.1 to 2.2 and then if i decide to go back to 2.1 i can??? please help
i have a non rooted n1 with 2.1 update 1 now if i update it with a froyo unroot version can i go back to 2.1 update 1???
Are you running a custom recovery image? If you are then you can make a nandroid backup of 2.1. If you aren't then the only way to go 2.2 > 2.1-update 1 would be to do a factory reset.

hi everyone
i just received my 2nd nexus one from google after my original one got jacked at the gym (dame thieves!). for some reason my new nexus one doesn't detect the 2.1 build ere27 OTA update, and i'm not able to upgrade to the developer build of 2.2 build frf72 because it requires I have ere27 before upgrading. can someone please help me? like is there a way to turn on automatic updates or provide me with a link to manually update to "2.1 -update1" (build ere27) from my current 2.1 build erd79
after using flash in the browser on my old n1, it's hard using 2.1 when knowing full-well i can be using 2.2
***EDIT***
Just to be clear, my n1 hasn't been rooted and I prefer not to root (in order to preserve my warranty)

Same question asked - you need to install ERE27, then FRF50, then FRF72.
Thanks mate!
So i rooted my nexus one to cm6. its was great, but beleive it or not i didnt like all the setting. I went back to the orginal stock rom which is 2.1. i'm trying to figure out if it will out back to 2.2 or 2.2.1 via OTA. if so how long will the OTA take or do I have to do somthing extra.
When you root the phone there's no ota update anymore, you can flash the stock froyo though.
Alright, so I updated my phone when the first OTA update was released, and it installed successfully no problems. After this I got into rooting my phone so that I could get rid of the AT&T crapware, use launcher pro, and enable sideloading for apps. I thought that I would check for another update since rumors were swirling about 2.2, and to my surprise it detected a package to download. I was able to download it, however it wouldn't finish installing on the phone and said that it could not be installed. Thinking that this was due to my root, I used Odin to flash back to stock and retry the install, and it still didn't work. So, after that I reverted back to the root, and decided to go and check the firmware and baseband version What is confusing to me is that for "firmware version" it says that I have "2.1-update1", but my baseband version still says "1897UCJF6" instead of "JH7". Now when I try to install whatever supposed update that is available, it downloads and then gets stuck at 50% in the progress bar when trying to install. So I guess my question is, should I be worried about this? Is this the current version, and does it just say "JF6" because of my root? Also, will I need to unroot if I want to install the 2.2 update whenever it comes out?
I apologize for the novel, I'm just trying to be as informative about my situation as possible. Any help with this would be greatly appreciated.
Thanks
JF6 is the stock firmware and JH7 was the ota update.

Alright thanks, but why is my phone still displaying "2.1-update1" if I still have the stock firmware? Is it because of the root that it is displaying JF6 instead of JH7?

JH7 was also considered 2.1-update1
there is not an official 2.2 yet
Okay well thanks, I think I'm about to just flash to a 2.2 ROM, I'm tired of waiting on samsung for 2.2

Hey everyone,
I rooted my nexus one when it was 2.2, now im trying to update to 2.2.1. However the OTA update wasnt taking, it failed and the installation aborted everytime. I search forums and found one saying to factory reset my phone, which i did. Saved everything with titanium backup. Now im stuck with:
Firmware: 2.1-update1
Kernal version:2.6.29-01117-g4bc62c2 android-build apa26#1
Build nuumber: EPE76
One problem is i do not get an OTA update to upgrade to 2.2 or 2.2.1. Also i did a manual update with signed-passion-FRF50-from-ERE27.1e519a24.zip and it fails and installation aborts. How can i get back to at least 2.2, but preferably 2.2.1.
Also when trying to restore my apps from titanium backup, it tells me my phone is not rooted, but I still see the little "padlock" unlocked when i boot my phone.
Thanks, hope someone can help
John
What recovery are you using?
fastboot, then recovery, used a zip i downloaded from another forum that gave me build epe76. just renamed it to undate.zip and let the phone do the work.
What recovery are you using? Stock? Clockworkmod? Amon_RA?
i guess just stock, all i do is fastboot the phone and hit recovery
Have you tried ROM Manager?
yes but i am getting an error that my phone is not rooted. Although it is, the padlock is open when i boot the phone. If I root it again will i be able to install 2.2?

There you go.
Unlocking the phone is one thing. Rooting is another. You need to root it over again, but it should be easier this time since you do not need to unlock your bootloader.
ok i will try but before i do should i upgrade to 2.2 or 2.2.1 first then root it again? Because that was my problem originally, i rooted it when it was 2.2 and could not get do the OTA update to 2.2.1 to work the installation aborted with an error every time.
No, root the phone first. Then you can put whatever the hell ROM you want.
It's like putting your pants on first, then your shoes.
Yeah root first cuz most of the custom rom already jumps to 2.2.1

Also, if you root first, you can make a full backup before doing anything else...

First of all I would post this in Q/A section. Second of all you need to use ODIN to get back to 2.1 stock before you flash cognition. Although I hope you know Cognition is NOT gingerbread it is froyo.
System version does not make any difference to flashing ROMs

You tried the one click root? It should be a simple process of downloading the correct update.zip and then flashing it through the recovery menu. Takes like 30 seconds. I don't think it matters what version of android you are on to root...
