Stock Unlocked Nexus One + root = voided warranty? - Nexus One Q&A, Help & Troubleshooting

Hey Guys
I have bought myself a stock unlocked AT&T version of the Nexus one
It has never been rooted and I am on FRF85 at the moment (that was upgraded from EPE54b to FRF85 using the manual update method
Questions:
1. Does unlocking the bootloader mean you basically sim-unlock your phone?
2. If I have a stock unlocked phone, do I need to unlock the bootloader to root?
3. If I dont need to unlock the bootloader, when/if I decide to root my N1, will I lose warranty?
I guess question 3 is dependent on 2 above
Thanks

Unlocking the bootloader has nothing to do with sim unlocking your phone, these are two complete separate things
1 no. but I think there is no locked n1 available, so it is unlocked quite sure
2 maybe, depends on your build number. I think you have to unlock your bootloader with the att version
3 no

regarding rooting without unlocking bootloader, see the sticky in the nexus android development section

@flybyme - thanks for your reply - i had a look at the sticky thread you were talking about rooting without unlocking the bootloader.
1. what's easier? Rooting with unlocking the bootloader or without the bootloader?
2. What's more fool-proof so-to-speak?
3. What would you recommend?
Sorry for so many questions but thanks for reading

1. With unlocking the bootloader is alot simplet BUT you will loose your waranty.
2. Once either process is complete there's no real difference since you can use the custom recovery in exactly the same way to flash any further roms.
3. I would suggest _without_ unlocking the bootloader. At least give it a try, the worst that can happen is it doesnt work.

There are 2 absolutely independent meaning to unlocked...
1. Carrier unlocked - can run on any network
2. OEM unlocked - can install/flash custom ROMs not signed by google/htc
So I guess when you say the phone came unlocked, it refers to the 1 point, aka carrier unlocked. To install/flash CM, you need to unlock the bootloader, aka, OEM unlock.
Thanks alot guys, Am about to read over the steps on how to install the cyanogen rom before I jump in.

question about oneclick root / unlocking bootloader for ROMS?

hi, i'm from the x10 forum converting to a nexus one =) I searched around and I'm a little bit confused about rooting for flashing roms. I see some guides about unlocking the bootloader first, then rooting. ( i think old method??) Now theres the one click root, am i required to unlock the bootloader first, then use the 1 click root, because i know the 1 click root doesn't unlock the bootloader.
so first do i have to unlock bootloader, and if i do, can i use the 1 click root with unlocking bootloader? and can i load a rom after i root without unlocking the bootloader?
I also read on a different website that unlocking the bootloader is only required for phones locked to a provider, so does that mean that if i unlock the bootloader, my phone will also be network unlocked?
Just want to get this right so i dont' brick my new phone tomorrow
You don't need to unlock the bootloader.
Once rooted, you will need a custom recovery to flash new roms.
Make sure you use a recovery that is compatible with your screen (SLCD requires the newer Amon Ra).
Check out the wiki:

Better to Unlock bootloader
One click root is an amazing thing. It helps you root your android and install recovery without unlocking bootloader and voiding your warranty. But its better to unlock your bootloader just to be on the safer side. Stock roms flash both the Rom and the recovery. Froyo 2.2.1 even reverts an already rooted device.
Warning: your warranty will be void if you unlock bootloader.

Wrong, the thread's 1st post states what devices it works on and the Nexus is listed...
"It works with almost all phones and all android versions. (including the i9000, Droid, Nexus One)"
Okay but why do we Nexus folks care that the app can get Samsung unlock codes and enable a feature that was never disabled on our phones in the first place?
And why would we prefer a Windows app to an on-device root method?

@danger-rat thanks for the info, i didn't realize that there would be a difference between slcd and amoled, I got the amoled one so i think i'm safe on most recoveries?
@galaxys and inferus- oneclickroot is the best, thats how i got my x10 rooted, but sony's epic fail is forcing me to change over to something more updated, i'm sick of being stuck on 1.6. so no worries about bootloader?
can anyone answer my last question, is my phone locked to tmobile only until i unlocked it? or does it come unlock, and it just a tmobile version because its compatible with tmo 3g?

The Nexus isn't locked to any carrier, but the hardware is specific to different frequencies. For example, I took my T-Mo nexus to the UK earlier this year, switched out the SIM for an Orange one, and everything was great. However, if I use an AT&T SIM, I will only get 2G speeds because AT&T uses a 3G frequency that's not supported by the T-Mo nexus hardware.
Do a wiki search on the carrier you want, and it will list the operating frequencies for their network - just compare with you phone specs for compatibility.

Any reason to unlock the bootloader?

It used to be that you had to unlock in order to root etc.
But now with one click root applications like SuperOneClick etc, is there any reason to unlock the bootloader? Is it required for any custom ROM procedures?

Not really (although it does make things easier to flash - using fastboot is very convenient.)
But then again, is there any reason to not unlock it? It has been shown numerous times that HTC will honor the warranty despite an unlocked bootloader, while it has never been shown that HTC has refused warranty service because of an unlocked bootloader.

Ah, so the only thing unlocking does is provide access to using "fastboot"?
I know; I warranty swapped mine that was bootloader unlocked I'm just asking for general information.

Yes, unlocking your bootloader = the ability to flash images to your Nexus One using fastboot. That's it.
What if I am not planning on using a new rom? I want to stay on stock, but say, just want to overclock. I don't want to lose any data.
Would that make sense to just root?

I think you can just root then via SuperOneClick.
I have another question about unlocked bootloader. How can I tell if my bootloader its unlocked? I know usually I have to flash slp to unlock it or set S-off and if I'm not sure it should still be locked, but when I flashed modaco rom it said something about unlocking bootloader. I didn't want to but couldn't abort! So when I boot into bootloader it doesn't say unlocked but any way to tell beside that?

You'd see a padlock icon at the bottom of the 'X' screen as you boot up if you are unlocked.
Thanks, so I'm locked.

Questions From a Would be Owner

Hello guys,
Just a few questions so I know what I am getting into
1) The phone can be rooted. However, if i want to run on a custom ROM or use mods such as the music mod, I would have to unlock the bootloader, yes?
2) Once the bootloader is unlocked, I would lose the 'Bravia Engine' feature of the phone. What else will I lose? For those who have lost it, is the trade off, of being able to run Custom ROMs and mods while losing the 'Bravia Engine' feature worth it?
3) If I have to send the phone for warranty, I could just re-lock the bootloader and send it back for warranty. Is there a chance somehow that they'll reject the phone if they detected that the phone's bootloader was tempered with?

No clue since mine isn't/can't be unlocked. The only reason for me to unlock the BL (Even though it can't be done) would be, to flash a custom kernel, beside that I don't see any other reasons why I should unlock it.

Once it's unlocked there is no way back.
So if you want to root your phone, use custom roms (without custom kernels) you don't need to unlock the bootloader.

Thank you very much for the reply.
I assumed as such from reading some posts initially, but then I went to the ROM section (If i am not mistaken) and there is a post on how to unlock the bootloader and then there is the Why section where it says that you could then use custom ROMs and mods which then confused me.
If i can use custom roms and mods without unlocking the bootloader, then I'll definitely be getting this phone.
I'll take advantage of this thread to ask one simple question: once we rooted the XZ and flash the Mods we find useful, we no longer get updates from the official Sony firmware in the future, right?

First backup your firmware with http://forum.xda-developers.com/showthread.php?t=2188129
You can go back at any time to your original firmware and you can have the updates via pcc or sus.

TWRP and ROMs for Note N920A w/ Nougat

Can I install TWRP for the AT&T version with Nougat? I have heard that if I try it will brick. I'd really like to install a new ROM so I can get rid of all the crapware that comes with the phone.

The 920A At&t cant be rooted as of yet and no twrp because the bootloader is locked...
Bootloader
I recently talked to at&t about getting my bootloader unlocked and a supervisor told me the only way to do so without bricking would be to being it in to an at&t store and they will unlock the bootloader.. anybody else have this told to them?
They're most likely taking about a Sim unlock not bootloader. Also there is a method for rooting it but you have to be on a specific bootloader and you can only use it on lolipop.

Ya, I know about that root method. Unfortunately, my phone decided to update itself a few weeks ago and now its on BL 5. So that's pretty much a no go.
In relation to bringing in the store for a BL unlock, I did specifically ask and made sure the tech I was speaking with knew the difference between BL and sim unlock. In fact, i made it very known that my radio was already unlocked, I done that weeks before i talked to her.
