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] 4.4.4 Carrier locked VZW, unlock bootloader?

I've been reading threads and found a bunch of unlock bootloader/root threads. It seems that people could unlock bootloaders, but then lost the ability with new OTA updates. I'm not entirely sure if that's the current latest info.
If I have a carrier locked (VZW) moto X, on 4.4.4 - is there any way to currently unlock bootloader? Do I even need to unlock the bootloader? Goal is to root/put TWRP on it with CM11.
Could I RSDlite to an older rom, and then use the guides?
Thanks!

If you have the regular Verizon Moto X and not the Developer Edition you'll have to try and get an unlock code via Chinese Middleman.

People never had the ability to unlock their bootloaders (except through the "middleman") - they were able to disable write protect using an exploit. The exploit was patched in the 4.4.2 update. The exploit never allowed you to flash custom roms. Only "safestrap-compatible, stock-based roms".
As the previous posted suggested - check out the thread in general titled "China Middleman Back??" - it is currently your only hope. Yes, you MUST unlock your bootloader to use TWRP or any custom ROMS.
DO NOT attempt to "downgrade" or use RSD Lite to flash an older version. You WILL brick your device if you attempt this.

Questions about sunshine unlock tool

Hi, I am using VZW X with stock 4.4.2 and I would like to purchase BL unlock code from Sunshine tool. However I am not sure if this is permanent. So basically I have below questions:
1, If I flash stock 4.4.2 after unlocking BL using that tool, will my BL be locked again? (Flash BL with same version)
2, If I flash higher stock ROM like 4.4.4 or future Lollipop after unlocking BL using this tool, will my BL be locked again? (Flash BL with higher version)
My guessing to those would be no and yes. Thanks in advance for your time to read this or even kind enough to reply me

First off, the sunshine doesn't provide you with the unlock code. It unlocks it for you and that's all. OTA's and sbf's will not relock your bootloader <inert stock warning about never downgrading>. The only thing that will relock it is the explicit fastboot command. If you had the code you could unlock-relock-reunlock to your heart's content but I believe sunshine will only work to unlock the first time.

Thanks. Can I understand your word as after I purchase unlock from sunshine I can flash BL to current version or higher version and still keep it unlocked? And for your explicit command I believe you mean 'fastboot OEM lock', is it correct?

Yes. It has been posted recently a few times around this forum which bootloader codes correspond to which android version numbers. Always flash a matching or higher version to what you have and don't be tempted to get around that rule by only flashing parts of an sbf via fastboot. It's very risky and has bricked a lot of people's phones.
Yes, "fastboot oem lock" (or mfastboot oem lock) is the only way to end up with a relocked bootloader. Mind you that's "relocked". There is no way to go back to "locked" status to hide that you previously unlocked.
Remember that flashing SBFs and taking OTAs will unroot but you can always root again with an unlocked bl.

To expand and add a little to what @cntryby429 has already said..
Unlike the standard/official way of unlocking the bootloader (getting the code and issueing a fastboot oem unlock uniquecode), using Sunshine to unlock the bootloader is exploiting a vulnerability on the phone. To put it another way, Sunshine is a "hack." You do not get the bootloader unlock code. Because its a Hack, it only works ONE TIME. So if you unlock with sunshine, then relock later, you will not be able to unlock again.
When unlocking the official way (using the bootloader unlock code), flashing roms and newer SBFs and OTAs does not re-lock you. Re-locking is only possible by following the process and doing a Fastboot Oem Lock. All reports so far have been, that if you use Sunshine while on 4.4.2 or lower, flashing 4.4.4 SBF does not relock you. I don't know enough about Sunshine, and I haven't seen it been said, so I don't know what will happen if/when Lollipop comes to the 2013 X. i.e I've not seen it asked/answered... What if lollipop for the 2013 X contains patches for the vulnerability exploited by Sunshine, will it undo Sunshine's effects and will you be locked again?
As for the Downgrade warning, and bootloader versions...
30.70 = original 4.2.2
30.71 = 4.2.2 OTA with camera update
30.B2 = 4.4
30.B4 = 4.4.2
30.B7 = 4.4.4

Re-lock bootloader

Hi,
Some time ago I unlocked the bootloader and rooted my device. Didn't know it was possible to root without unlocking the bootloader (yes, i'm quite new to rooting etc.). Now my phone has a defective headphone-jack and I need to send it on repair. Anyone know how to re-lock the bootloader so I still have the warranty?
Currently running sLIM 4.8 by Wajk.

Use flashtool

Thanks, but it says on Sony's website that the phone stays unlocked even after using flash tool?

Code:
fastboot oem lock
Never done it in Sony phone but most of HTC, Nexus and few other brands I'm locking just with this command.

Need help, bought phone, it's on Global ROM but bootloader was relocked

So this is my second Mi Mix. I know my way around it a bit. Anyway I was trying to flash TWRP and it won't work. It appears the bootloader is locked. Apparently the original retailer who sold the phone flashed the global MIUI rom and then relocked the bootloader and reflashed the original recovery.
I have already requested to unlock through Xiaomi but I'm not sure if it will work being on this rom... once I get the text back from them that is.
I'm unable to flash the Chinese stock rom in MiFlash because the bootloader is locked. I've tried just about everything but it appears I'm stuck waiting on Xiaomi to send me the unlock text but my concern is that I won't be able to do it because I'm not on the stock rom.
Any input would be greatly appreciated.

You dont need to request for another unlock code. The unlock code is associated with your Mi Account, meaning you can unlock any Xiaomi device once you sign in with your Mi Account on the device. Once signed in, you just need to use the Unlocking app.
Considering this is your 2nd Mix, I'm assuming you had received an unlock code for the first one. If so, you're good to go. You just need to do as I mentioned above.
If you dont have an unlock code yet, once you've received it, the procedure is fairly simple. Just follow one of the guides here and you'll get to wherever you want,be it Official, EU or a custom ROM.
Hope this helps!
Cheers!

The first one I bought already had the bootloader u locked so I don't have a code. Once I receive a reply from Xiaomi with a code will I be able to unlock even though it's on the global ROM and not stock?

Yes. once you have the code, you can unlock regardless of whatever ROM is installed on the device. FYI, my phone came with a Vendor ROM but locked bootloader just like yours. I don'"t think the Vendor relocked it. I'm assuming that Vendors receive signed Custom ROMs from Xiaomi which is then flashed by Vendors using stock recovery. If they have a signed ROM file, the bootloader doesnt have to be unlocked. It just installs like an update.

Didn't know you had to unlock bootloader for Chinese ROM with miflash, you sure it's not the way you unpacked the file.

Yeah I'm pretty sure it requires bootloader unlock. The first Mix I had was the 128gb version and I sold it last week. Before I sold it the guy wanted me to flash the chinese rom back and I did it using mi flash and it worked just fine. Used the exact same file this time and it won't work, it fails right off the bat. Also in the guide that's posted here for flashing the Chinese rom it says you need the bootloader unlocked.
I guess it's one of those things that people assume the bootloader is already unlocked if you're flashing the Chinese rom since you'd have to have unlocked it already to get off of that rom in the first place.
I'll just sit back and wait for my unlock code I guess. Hopefully they don't take the full 10 days to get back to me.

Unless you got vendor ROM.

Vendor ROMS aren't signed or sanctioned by Xiaomi.
Given Xiaomi doesn't even produce a general Global ROM for some models of it's handsets (such as the Mix) because they only sell them in China, it would make little sense for them to then sign Vendor ROMs for such handsets given they're all but exclusively used by international sellers.
