Stock Unlocked Nexus One + root = voided warranty?

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.

[Q] Rooting N00B Question

I have the Verizon Dev Edition Moto X. Understanding that I won't void my warranty if I unlock the bootloader, it has been stated in many threads that even if you re-lock the bootloader it still will give you a warning boot screen (unlocked BL) because there are flags that are permanently changed on the phone once you unlock it.
That being said, I am very non-committal, so I first want to just root the phone and install safestrap. I have seen a ton of tools out there that root your device, however I am confused as to which one I should run (e.g. slapmymoto, pwnmymoto, etc). I am on the latest firmware (4.4), so I think it requires you to downgrade? Any words of sage advice is appreciated...
Also, any changes I make to my phone, I can always RSDLite my way back to 100% stock correct?

I don't know why the unlocked bootloader warning screen would stay set if you relocked it, but you can change that screen to display whatever you want. See here for details:
http://forum.xda-developers.com/showthread.php?t=2417961
Since you have the dev edition, you should be able to unlock, install TWRP, and root without slapmymoto or pwnmymoto. I did it all AFTER installing the latest OTA, and I had no trouble.
I have not used RSDLite, but that is the way I understand it.

Sell or trade your dev edition. Installing SafeStrap on that phone is such a waste of time and energy.
Or read more. There are ways to remove the boot logo screen.

Can anyone confirm whether or not unlocking the boot loader sets a permanent flag?

It appears to. And the statement about still receiving the unlocked bootloader warning after re-locking the bootloader is correct.
However, since the warranty of the Dev Edition is not voided, just unlock the bootloader, root, and then get rid of the message by replacing the logo.bin

You bought a dev edition, it doesn't matter if the flag is set or not.

[Q] Unlocking/Re-locking Bootloader

I used to own an Xperai Sola. Before unlocking the bootloader I didn't know that I had to backup the DRM keys so that I can get back the "Bravia Engine" and "Download music Info option for Walkman" after the bootloader was unlocked. The information that we can backup our DRM keys came 6 months after I unlocked my bootloader.
These are my questions:
On Moto G 2nd gen do we need to backup something similar like the DRM keys of Xperia Sola?
What function do we lose when we unlock the bootloader other than Warranty? Does OS/Android update still work?
Does re-locking bootloader takes the phone back to its previous unlocked state?
@Falcon G
@vinaybaboo
@bhavin192

2. You can update phone after unlocking bl if you don't make changes to OS i.e. Xposed etc.
If you update even you have made changes to OS your phone will go into Bootloop
3. Yes Re locking and flashing stock firmware takes it to locked state
@NWKENT can answer this Questions more clearly

I´m also with similar doubts. I came from Samsung-way of unlocking bootloader.
Just to ensure if get it right, If I just put root on device, I still be able to update original rom from Motorola ?
It´s a pity we can change anything with xposed (in order to keep upgradable), bcos it´s small things we get used to, and we miss on stock roms...
Thanks,

Thanks for your input.
Please @NWKENT @Falcon G @vinaybaboo can you kindly answer this question?

I guess if you wipe data and unnistall xposed and then flash stock recovery, you will be able to flash via OTA. No need to unroot

1. No you don't need any DRM keys
2. U lose nothing rather than your warranty. Ota works if you don't install custom recovery and change the kernel
3. The new locked state is different than the OEM locked one

Falcon G, thanks a lot for replying.
If the new locked state is different than the OEM locked one, then if a user wants to unlock the phone a second time, does he follow the same method he used to unlock the first time?
So, once the phone has been unlocked it is not possible to lock the phone to back to its OEM locked state?

Yes you will be able to unlock the device.
And no you cannot get back to the original oem locked state

Dangers of unlocking?

Hello,
My Z3C has bootloader unlock allowed: no.
Is there any problem if I try to unlock it anyway?
Thanks!

No there is no problem, you probably won't be able to unlock it and that will be it.

Of course just remember that unlocking your bootloader will permanently disable some DRM-protected features.
The way around that is just to use the root exploit and backup the TA partition (good guide here).

If it say unlock allowed no, there is no way to unlock it so no point trying. But no trying won't do any harm, it's just pointless.

Some people were reporting that after sending in their phone for some hardware issues the phone they got back (the same one) had changed to booloader unlock allow yes. So this could be your last resort if you are lucky and willing to wait a bit it might work. Just make up some hardware issue like random crashes, rebooting or something.
And save your TA partition if you do that so maybe someone in this forum can spot the changes of before vs afterwards which would point in the direction what actually changes.

[Q]s-off vs unlocked bootloader

What are the benefits of s-off over just unlocked boot loader

by unlocking bootloader u can root ur device, can flash custom recovery & custom roms on ur android device....

I don't have this particular device but I will tell you the general information and you can work with that.
About Bootloader(Unlocked Bootloader):
The bootloader is like a BIOS of your PC. It is the thing that is powered on and verifies all hardware and is responsible for making connection with the hardware. This can either be unlocked or locked. When you have a locked bootloader you can still root (if an exploit is available). You can even install a recovery or custom rom if an exploit is available (like BUMP was). What was it doing? Signing the images for your so the locked bootloader will think it is the OEM image. In most of the cases this is not so happy. Usually you can't flash a recovery or a custom rom or stuff like that with a locked bootloader. Some OEM's provide websites to unlock the bootloader (with the cost of losing warranty; well not really). This is the case of Sony, HTC. Some Oem's don't provide this.
About S-off:
What does S-off mean? Security off. Your device will come with S-ON always unless it's a Dev edition (correct me if I am wrong). What this does is it doesn't leave you to do very advanced operations related to the EMMC (the Nand chip). You can't flash a bootloader you wish or stuff like that. Update radio partition. In some cases system partition is also secured so you can't flash a custom ROM. By S-off you get full control of your device but if a mistakes occurs you will end up with a hard-bricked device.
Peace. Hope you understood.

Things is, i was more concerned about the practical info about this device specifically because I have read that with just bootloader unlocked, the roms that i'll be able to flash will only change the visual and not so much with the kernel etc. I don't understand why people would choose to S-OFF for this device for other than just relocking the bootloader.

Sorry I can't really help you with that information I don't know if you can flash a Custom kernel with S-on. Never had a sony. Someone will help you out soon.I hope.

i'l bump this question up then :/

I think S-off is a term unique to HTC devices. Its the equivalent of an unlocked bootloader

yes but nth to lose on HTC except warranty (still subject to which svc ctr tho) while on Sony, losing DRM keys (w/o backup) are like downgrading ur phone full capabilities.

Is there a way to root without losing keys? I have Z3 LTE D6603 atm.
Sorry if it's a dumb question, I'm new here. And also new to sony rooting, which seems much more complex than my old Nexus 5 lol

Not really, you can flash kernels, roms ( aosp roms etc ) with unlocked bootloader, S-off gives you other stuff like changing mid, cid, sim unlock, downgrading/upgrading bootloader, converting to full GPE or dev edition, unlocking bootloader without need of HTC, flashing splash image, custom bootloaders, even converting to Windows ( if available of course ) locking it instead of re-locking it, restoring it to full stock state ( which is not possible without S-off ), simply put your device has no limits with S-off on HTC.
Anyway S-off isn't really needed unless you care for the things above ( if Sony even has S-off ), Sony has poor development so S-off isn't even needed or unlocking bootloader since basically all you get is aosp roms, stock alike roms are flashable with locked bootloader as far as I remember.
