So the bootloader on the N1 is designed to be easily unlocked, yet it voids the warranty. Also, it can't be re-locked. Can someone explain exactly why it can't be re-locked? Is it because Google / HTC can't guarantee what low level changes have been made? If so, shouldn't it be technically possible to flash some sort of master image that overwrites the entire phone back to default, including the lock?
If I've unlocked the bootloader, and either keep the stock OS or go back to the stock OS after trying Cyanogen, will OTA updates work? That is, does the unlocked bootloader prevent OTA updates, or just a non-stock OS?
There's a looooong thread about this in Development.
Guess I'm search challenged, because I can't find that thread. Can you point me to it, or summarize it?
Here you go man... start here:

Whoa. Ok, I see what you mean.
Anyone know about my other question?:

OTA updates are not affected by unlocked bootloaders.
you don't need OTA updates when you are running a custom ROM....We get all the OTA stuff BEFORE, repeat BEFORE, OTA even comes out....Un-lock it and get the best and badest!!
Does anyone know how i can get froyo on my phone with the EPF21B build? Could i change to the ERE27 build WITHOUT rooting my phone? Or flash pauls version through the stock recovery image, without voiding my warranty? Thanks for any help
same problem.
my phone is EPE54B
HELP!!!
Gotta root until Google sort it out I'm afraid.
I have ERE36B with locked bootloader. Can I just update or do I need another update file?
You're on an awkward build... I very much doubt there will be an upgrade path for you.
You will most likely need to flash a mainstream PASSIMG.ZIP (AT&T EPE54B or Vodafone EPF21B) and update from that when Google release one.

Edit: Actually, maybe you should listen to him. After clarification it seems that there were un-original roms out in the wild that didn't need an unlocked bootloader. If you updated to that ROM yourself, even without unlocking then you may not see an upgrade at all.
Old post below for continuity's sake.
--------
Don't listen to him. It seems he is telling you that you will need to unlock to upgrade. If you aren't going to unlock yet, just wait, there will be an OTA update for you too, you just have to wait for Google to send it out.
Google will not force you to unlock your phone.
Is there a way to go back to ere27 so i can update now, without unocking?
Dont mind if i have to do a factory reset or something like that

EPF21B is the official euro shipping ROM.
You can't change it back to ERE27 without unlocking the phone, period.
If you don't want to unlock, you'll have to wait until Google issues the OTA for the official euro phones.

Thanks for that completely incorrect post.
I am not telling you to unlock, both can be flashed in the same way you flashed ERE36B as they are official released images.
As ERE36B is a release that shouldn't be out in the field, I doubt an update will be made for it.
So, since I am not on Vodafone or AT&T, what should I update to? AT&T EPE54B or Vodafone EPF21B?
There has to be a way to restore the phone to factory state and factory ROM?

Sorry about that, it seemed to me that you were telling him he would never get an update without unlocking. But he did mention that he was still locked and had that release. I don't know how he got that one, but if he is truly locked wouldn't it make sense that Google knows of the phones out there with that version?
I still don't think it would make sense for Google to not give those phones an update, and to force them to unlock to upgrade.
Am I missing something important here that's really messing up my understanding?

Except that the factory ROM is different from one to another.
Tmobile factory ROM : ERD79 (which can then be updated to ERE27).
ATT factory ROM : not sure but the one before EPE54B
Europe factory ROM : EPF21B.

I think so.
There are certain ROMs that were leaked, these can be installed without unlocking the bootloader as they are release signed. No phone sent out by Google came with ERE36B, you had to install it yourself. There is also no way back to stock ERE27 without unlocking the bootloader.
My reckoning is that as this particluar ROM isn't meant to be in use by the public an upgrade path is unlikely, hence the advice to flash to a 'legitimate' release image (no unlock necessary) which will definitely be upgradable.

Thanks for explaining. I'll go edit my original post.
Thanks Rusty. What rom should i update to then? Is there another rom i can downgrade from, or is it generally impossible to go to an older rom with locked bootloader?
Can't go older unfortunately, else it would be a no-brainer.
As for which one, I doubt it matters, but I would expect EPE54B to be the next updated.
cant you just flash pauls prerooted version?

Doesn't work, cancels installation when it doesn't find the right signature.
yeh, tried that, Wont work with locked bootloader. Tried all ERE27 images, renamed to either passimg.zip or update.zip, and same for all frf50.. Only one thing left to do i guess, and that is wait.
Having the Same Problem,
Hi, I have a Nexus One from Vodafone, and have unlocked it, however, I still can't get it to update to Froyo FRF50 so I can then further upgrade it, I am currently on build EPF21B which I think Vodafone have mucked around with, because I have just updated a Friends Nexus Manually with the same file not problems, mine keeps coming up with, first:
Froyo+E:Can't open /cache/recovery/command
Then fails on this:
E:failed to verify whole-file signature
Can any of you kind people out there confirm that there is something slightly odd about the stock Vodafone ROM,
Thanks for your time in this matter, I assure you that it is deeply appreciated
Kind Regards - Ashe
My question is how do I root without unlocking my Bootloader? I've downloaded PAQman's Stock to FRF83 Rooted but I'm afraid of a couple of things. First, I'm already on Official FRF83 stock, Second, I don't want to unlock my phone since its only a month old? Any help would be greatly appreciated.
did you get FRF83 directly from ERE27? (or other eclair rom) I'm guessing that you had actually upgraded to FRF50 first right?
yes, did FRF50, then FRF72 then FRF83. But right after I flashed the stock FRF83, I saw another update by PAQman "from whatever to FRF83" rooted. So, would it be safe to reflash PAQman's FRF83 Rooted over stock FRF83?
You have to unlock your bootloader to root. There's an alternative way to do it with out unlocking the bootloader, but I wouldn't recommend it.
As of right now HTC is still honoring the warranty as long as you are able to put the stock rom back on your N1. http://forum.androidspin.com/showthread.php?t=2630
hi kobecamp2009,
I was wondering what are your sources were on the fact that they are honoring warranty if you can reflash stock? Everything I've read from various posts here seem to indicate that it's a crapshoot. Sometimes they will honor warranty on unlocked bootloaders, other times not.

according to an employee of Google i talked to, they will try to flash it to "original" state no matter what, sometimes they can sometimes they cannot *with an unlocked bootloader*
They'll flash to original state if possible, but then will they charge us 183$ for a repair?
I really wish Google would leak a Froyo build for our phones. I really need wifi tethering...Froyo would keep me satisfied until my warranty ran out!

no, if they could flash it without replacing the motherboard then they won't be charging.
Froyo for us should be sooner than Mid-July i'd say since Droid is getting its by Mid-July.... so... keep praying
im gona send my phone in as a replacement, but i want to make sure everything looks stock before it send it in, i found a couple of ways to return to stock but i keep getting signiture verified failed, and i assume its because i have an unlocked bootloader, can any 1 help?
You should be able to find the stock rom for unlocked users in the development section. Just flash that and you will be back on stock.
But you can't re-lock the bootloader. When you unlocked it you voided the warranty, and it stays that way.
If it is a physical hardware problem, you should be able to still get warranty though.
Sorry, I meant to say my bootloader is locked, I don't have a problem with the rom, but the recovery. I am on ra recovery atm and I want to go back to google's stock. Is there anyway to do that?
Im pretty sure this works for all phones but if you flash Official OTA it will put everything back to stock(except bootloader if it has been unlocked) but doing this you will also loose root as well
i would wait for some one to tell you another way to get back to stock recovery, im sure there is a way to do it in adb or something.. Flashing the official OTA should be like a last thing wanting to do
Look for the stock recovery Tom for your phone then just flash with fastboot. That's the easiest way that I. Did it.

He cant do fastboot, he has locked Bootloader.
yeah, it saids verification failed and wouldnt let me flash anything onto it
oops my bad. I had an unlocked bootloader. My other phone is locked.

Yeah i had the same problem when i tried to revert mine to stock. My bootloader was lock and wouldnt let me reflash the stock rom with verification failed.
NOT SURE IF THIS IS THE CORRECT WAY, DO AT YOUR OWN RISK :
I renamed the image to PASSIMG.zip and booted into bootloader. The bootloader automatically searches for PASSIMG and when it found it went through an update/installing process which took about 5minutes. When it booted phone was unrooted again, and had the stock recovery.
Once that was done, i installed the FRF85 (i think) update.zip from bootloader recovery, then did the same with update.zip for FRF91.
Again not sure if this was the correct way as i have never seen posts directing to do it this way - have posted questions about it in the past week or two, but never got any responses...
I'm gonna bump this thread up again. I tried downloading the original PASSIMG file for the stock and when I try and flash it by putting it on the SD card I get that the main file is older and the install is aborted. I can't fastboot the files because my bootloader is not unlocked. I'm currently running a FRG83 based ROM, does this matter? I'd like to return my phone to stock recovery and stock ROM, but so far every attempt has been met in failure... I guess it's an irony of rooting a phone without unlocking a bootloader. If you have to send it in for repairs you have to unlock the bootloader to return to stock, or you can't return to stock and you're left with custom recovery and root... either way HTC knows you're rooted. I know my issue is a hardware issue, but it would be my luck they decide to void my whole warranty.
You can't just PASSIMG your way back from FRG83, if you have it - since there's no PASSIMG for FRG83 yet (at least I'm not aware of one, and looks like Google isn't either), and the system is designed not to flash older builds. Trying to use PASSIMG to return to older builds requires some heavy preparations (has to be rooted, then downgrading HBOOT and probably flashing initial system.img from an older build through adb in recovery, using flash_image). It's possible and not very hard to do, but most probably beyond "1-click-root"ers' skills. All the relevant info is in the Wiki, so if you want to attempt it - you can try.
Unrooting FRG83 (reflashing stock recovery from FRF91, removing su and Superuser.apk from root shell) might be easier.
Also, put attention that if the phone has SLCD screen - the official stock FRF91 won't work on it.
I actually was able to PASSIMG to FRG33 then OTA back to FRG83. which I thought was odd due to the fact that I was on a FRG83 based rom. Oh well, it's 100% back to stock now. So even though people say that a rooted/unlocked phone only voids your software warranty I don't have to worry about it. Yay for keeping a locked bootloader.
Hello guys! I am new with the AHD and I wanted to know if its sure to update to stock KitKat with Motorola software, Im asking because I want to root my phone and install a ROM, but in the rooting tutorial it doesn't say a thing about if its safe to update or not
The Atrix HD is supposed to get the Kit Kat update sometime this quarter.
You probably will not be able to update to the official kit kat using Over-The-Air (OTA) unless you are running a stock ROM with stock recovery.
To install a custom ROM, you should root and unlock your bootloader. Remember, unlocking the bootloader will void your warranty.
To follow up what audit13 said, you will most likely need to flash your phone back to complete stock in order to be able to update to the official KitKat upgrade when it is released later this quarter. The good news is that, with an unlocked bootloader, it's a fairly painless process.

+1 for an unlocked bootloader; however, unlocking will probably void any remaining warranty.
I unlocked my bootloader about a week after I got my Atrix HD. I used it for a week to make sure it was functioning properly, hardware-wise, and then started flashing custom ROMs.
