Recovery Image and Cyanogen

Maybe someone could provide some details as to what the recovery image and cyanogen does?
From using it recovery image is a mod for the boot loader so that you can flash the cyanogen zip. If I am incorrect please explain.
I had another question about updates.
boot loader - is it necessary to update to a new boot loader if there is no cyanogen since you won't be using it yet.
cyanogen - is a update of the cyanogen basically an update of the android os? eg. if there was an android 2.2 then there would be a new cyanogen and I would have to install that to get the new os.
It is no longer possible to update through the network after you have modded your phone, so the only way to update is by installing cyanogen? if so does that mean every time you want to do an update your data will get deleted?
THANKS

First Time Root keeping Stock Rom

Hi all,
I have gone through the rooting for dummies guide, but as my intentions are slightly different can anyone help me by briefly writing down the steps for Rooting and Keeping Stock Rom and keeping Stock Recovery so that I can update it when google releases 2.2.
Would highly appreciate it.

You shouldn't have any problems updating to 2.2 if you flash amon's recovery.

Which recovery you have has no bearing; so long as you're rooted, you'll be able to download 2.2 and flash it. If your goal is to make the transition from 2.1 to stock 2.2 as easy as possible then, sure, stay with stock. I figure CM will probably have a 2.2 ROM out faster than most stock phones would have been able to download it via OTA, though, so I'm sticking with CM5.0.6 and will update whenever CM does.

same here.

I am using Enom. With Titanium backup it really doesn't mean much to switch roms

My understanding is that once you install a custom recovery you can not get ota. They show up as available and are clickable but fail. This was the experience described at the last ota. Are you folks that are saying you can still get ota after installing a recovery speaking from experience? In other words did you have a custom recovery installed and sucssesfully update at the last ota?

Thanks guys for the input, but like krabman said, i also heard if you put a custom recovery you cannot get the ota to work! Any confirmation on that?

with custom ROMs and custom recoverys, you will not be able to install OTAs. Most custom ROMs disable OTAs since they kinda break the custom ROM functionality like root access. Most OTAs reboot the phone into recovery to update the software. A custom recovery like Amon RAs recovery can only accept ROMs and updates signed with test keys. Any update released by Google/HTC which is officially signed will not work.
But this should not prevent anyone from installing custom ROMs and recoverys since most cooks include the latest updates very soon, sometimes even before the official releases...

What if you follow the Original Shipping Tutorial to restore you phone's original recovery system?

I would imagine if you followed that you would be back to a completely stock phone that would work with OTA updates.
But, if you don't plan on running any custom roms, why bother unlocking the boot loader at all? If you haven't already done it, I wouldn't.

Amon ra recovery can only accept ROMs and updates signed with test keys. Any update released by Google/HTC which is officially signed will not work. Nor will the stock recovery work since it loses its official signature when it gets ripped so the ota cant use it because it requires an officially signed recovery to install itself with. If this is incorrect then I look forward to being properly schooled. I can say that I have yet to find anyone that had a custom recovery on at the ota last time that was able to get the update and install it ota.

Well that's great news. I regret unlocking my phone more every day.

To be honest this is pretty much a non issue as far as ota goes. The stock rom with the ota on it, or in other words the lastest official release, will be available to download here within hours of its release and you can flash it like any other rom. If they do a rolling release it may well be you can download it before it becomes available over the air.

The reason I want to unlock the boot loader is to only use the metamorph and a few other launchers. I am a theme-freak so I could customize the look of the stock rom, but now that you all mention it, I guess I will stick with the Stock find other ways to theme it.
Thanks everyone.

After flashing CM's ROM, I was able to completely restore my phone to shipping state (sans relocked bootloader, of course), and then perform the 2.1-update1 OTA.
So yes, you will be able to update to 2.2 as soon as Google releases the OTA, but you'll have to completely revert back to stock in order to do it?
I'm not really sure about what I'm talking about, but I just wanted to confirm that you CAN perform OTA updates even after flashing a custom recovery image/ROM.

OTA updates and stock rom question

I got my Nexus One last week and quickly rooted it and flashed CyanogenMod. Before I did, I did a nandroid backup of the original ROM. If I flash that original ROM back, will I get OTA updates again or is there something more I need to do?

you will get ota updates again if there is.
wipe, before you restore.

My understanding was once you unlock the bootloader you're done. No more OTA updates.

Thats not true. The ROMs cooked here are simply put, blocking updates from TMobile or Google. From what i understand Google will be posting updates on the google.com/phone website.

Its the recovery that is the holdup is my understanding. Any ota that requires the recovery to install will fail because even if you reinstall back to the stock recovery it is no longer officially signed and the ota will only install with an officially signed recovery. An ota that does not use the recovery like the ota 3g update/fix will install fine unless it is blocked by the rom developer. All of this is a non issue anyways. From the point of initial release to when you can download the stock 2.2 rom and flash it yourself should you choose will be a very short.

Why wouldn't a restore of the original recovery image not be signed? Isn't the signature part of the image itself?

I dont understand this myself but as I read it something about dumping it strips it of its officially signed status. If I were forced to guess, and this is only a guess, its to prevent modifying it and reinstalling it for the obvious reasons. As it is I can say that despite seeing a thread like this daily at times not a single person has reported having reverted and then beinng able to install the 2.1 ota when it went down on any of them and yet there must of been scads of such people who tried just that. A number of them on the other hand have reported being able to get ota that did not require the recovery to install. In the interest of fairness I am repeating what I have read, I posseess no expertise myself. If this is inaccurate I hope that I will be corrected and we will all learn something.

Well...when 2.2 is released, can you just go to google and download it or is the only way to get the update via OTA?

Nah, that is what I was saying, you can download a stock 2.2 rom here and flash it via recovery like any other rom as soon as the smart types get er whipped up, should be very soon after release. I havnt seen anything official but as said above I have read that it will be up on googles phone site.

You can download the original Rom from Modaco and in fastboot flash the signed system file boot file and recovery if you do that u will receive the ota update from Google its the recovery that effects ota there's detail steps on nexus one forum search rolling back to stock Rom I did it and it works hope this helps

How can I upgrade to the latest 2.2?

My story is sort of a strange one.
I originally unlocked my N1 and installed a 2.1 custom rom on it. Then Paul released his 1 ZIP to flash upgrade to F50. I got that and all hints of my custom rom seem to have disappeared. However I'm not sure if I will get OTA updates now, or if I can simply flash the new ZIP to give me the latest froyo because of this custom ROM that I can't remember its name.
I would go back to stock roms and everything but I don't want to lose all my data and apps, plus I don't know how!

So your saying you flashed the froyo update and your Rom is gone?
If that's what you meant... than that is what is supposed to happen.... you lose root when you flash that update.... but Cyanogen made a quick fix for that

[Q] How to fix my N1 that I just got

I just got a Nexus One that was ROMed and rooted (has RA-nexus-v2.0.0 recovery) and enom's 2.14.2 ROM. I don't very much like it (seems slow). I am trying to go back to STOCK Android 2.2.2, with Root access, in preparation for 2.3's release. I know how to use ADB so that's not my problem. I've downloaded FRG91 in hopes that I will get an OTA to FRG83G. Now here's where I start getting problems. I go into Recovery, go to Flash Zip from SD card, and try to flash it, but it says it doesn't have signatures. md5sum is correct so that's not it. Can anyone help me out? I've tried doing about 10 different things so far and none of them have worked. Maybe someone else has seen this? TIA.

Have you try to toggle signature verification off?
Here's a rooted 2.2.2 rom

I haven't. I think I might have found a way to get this baby working. I'm working on it now. If I need anymore help, I will re-ask in this thread. Thanks for the tip though, didn't think of that!

Alright. I think I got it to work. Had to do some fenagelling, but I got it back to stock 2.2.2 Official.
Admin, can you delete this post?

You can't flash stock roms without stock recovery, Google's signature is on the stock roms so only stock recovery recognizes it. There is also a option in your custom recovery to turn of signature verification. I wouldn't recommend that you try, because I don't know what would happen. But it's a option, if your that hard pressed to go back to stock. Another note, since the G1 days the devs built their roms to stop OTA updates. So if you flash stock recovery, then you may need a stock rom to receive a OTA. I wouldn't get my hopes up about getting Gingerbread or Honeycomb OTA. I don't see anything on any android forum about this happening, I could be wrong though. If you can get your hands on a stock recovery image then you can flash with adb or fastboot commands. Good luck.

Turning off signature verification works fine. No problems whatsoever flashing stock ROM/updates.

OTA updates have nothing to do with a stock recovery. All newer versions of Amon_RA and CWM custom recoveries have signature verification toggles, so you can install OTA updates without problems.
The only thing is that you need to have a stock ROM (not de-odexed, and not an AOSP build) for the OTA update to install.
