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!!

Yesterday I received my one from T-Mobile UK with 1.28.61.7 on board. I am not quite a noob but I have always had devices with WWE un-branded firmwares. There is no bloatware on the device but I guess that, until s-off, I am dependant on T-Mobile to provide updates.
I am not particularly bothered about custom roms and, in the past I have usually gone with stock rooted roms so that I can go add-free and remove anything that I do not require.
Last night I lied awake thinking about the implications about what I have and I really need some informed advice about it.
If I root my device, how can I return it to stock in the future so that I can receive any ota updates that T-Mobile may eventually offer without a RUU which appear to be quite scarce?
Am I able to install custom firmwares based on higher firmwares ie. 1.29.401.12 and, if yes, will I be able to return my device back to stock without an RUU as backup?
I am most confused about the scenario which I have. I love the device apart from the 3 dot menu bar which is doing my head in and am confident in my ability to remove it but am worried about my safety net if something goes wrong. Please somebody enlighten me as to what I am and are not able to do. Thanks in advance.

You have options. Firstly S-Off is not likely to come soon if at all. HTC made it such a pig to crack, the entire year I had my One X it was never (to my knowledge) posted here how to do it. But it's not really that necessary. S-Off just adds convenience for flashing kernels in recovery at the same time as a ROM. With S-on you just have to accept that a bit more faff is required using fastboot to change a kernel.
(Side note: I have not had my device arrive yet so I am staying out of the development threads. I heard a rumour you can have a flashable kernel for this phone with S-On. Anyone know if this is true?)
Once a custom recovery is on, take a backup of your stock ROM. That way if you ever really wanted to go back for an official OTA update, you could restore the backup, flash back the stock recovery and relock the bootloader. Not sure why you'd want to go this route though.
Being on XDA and knowing how to do this stuff means you can get all the features an official update will bring you, usually months before any carrier will be providing it. You'll just be going through all this extra work to get an update that has been in the custom ROMs for ages.

Thanks for your answer. As I said, I am not quite a noob :silly:. The reason I am looking to go back to stock at a later date is that I believe (rightly or wrongly you tell me) that to update firmware in it's entirety, it is necessary to use an official update from the provider.
If I back up my official stock rom after I root, are you absolutely sure that when restoring this backup, I will be able to receive official ota updates? It is not that I don't believe you, just want to be 100% sure.
Edit Perhaps we are more likely to get s-off now that we are on Quallcom not Tegra?
S-off together with super cid would give us the ability to use any RUU for this device which gives us an excellent safety net.

It's ok. It's always best to be sure before attempting something!
You will not loose out on anything by not using an official update. All it will be is the stock firmware with T-Mobile's add touches. More often than improvements to the stock firmware, carries tend to restrict the features of a ROM and add bloatware (like game demos you can't uninstall) because they have made a deal with a game developer to make some money forcing them upon you.
Even without a nandroid backup you'll still be able to download and flash the stock firmware somewhere here. Basically anything you do to your phone you will be able to undo if you so choose. The only exception to this is that if you re-lock your bootloader, HTC will still be able to tell that it was at some point unlocked if you wanted a warranty return.
Yeah, as long as the stock bootloader is available, you just need to flash it after restoring the backup, and the updates should arrive.
The firmware might be flashable without the RUU or OTA, it was on the One X, but it was necessary to relock the bootloader.
I say go for it, mike1986 has the stock ROM in the dev section as well as his stock like improved ROM.
I have an xt1053 with unlocked bootloader, root, and TWRP. When Lollipop is released for moto x, will I lose all that and have to unlock again? What are the risks of updating?
Maybe, probably, who knows. I make it a point to never accept OTAs. Within a day or two devs will capture it, work it over, and release a version that is safe to flash. Just be patient one it's released.
OTA will always break root so you have to re-root. It does not relock your bootloader so you don't have to re-unlock.
If you have an unlocked bootloader there's usually no reason to avoid OTA. only those who have root with locked bootloader avoid OTAs since they risk not getting back root. Unlocked means you can flash custom recovery which means you can get root back.
BUT: You should always revert to stock recovery before taking OTA. doing it while carrying custom recovery will at the very least result in failed OTA, or worse.... So just revert to stock, take ota and thereby losing root, flash custom recover, flash superSU and have root back.
* So obviously this means you shouldn't take OTA unless you have the appropriate stock recovery on hand to flash back to stock.
xt5300 is an HP Pavilion Notebook PC. I think you mean xt1053.

Doh! That's what happens when I don't get sleep. Edited to fix. Ty
I've searched and found variations on these questions in other posts, but I didn't come across any pertaining quite to my situation, so I wanted advice before I do something wrong and brick my phone.
I have a Sprint Moto X, unlocked & rooted, running 4.2.2 (I think pre-camera update). I'd like to upgrade to stock Sprint Lollipop (when it comes out) & stay unlocked & rooted.
My understanding of the steps that need to be taken:
1. Unroot my device
2. Re-lock my device
3. Flash TWRP and boot to recovery
4. Flash stock Sprint Lollipop
5. Unlock, then re-root device
Is any of this extraneous, or am I leaving anything out? Do I need to upgrade to KitKat before going to Lollipop?
I also have Xposed installed and I have tweaked the PRL on my device ... this shouldn't complicate the upgrade, right?
Relocking is useless, and unless you know what you're doing, flashing stock updates in custom recovery shouldn't be done. You don't necessarily need to unroot either, just make sure all stock system files are still in place.

i have a sprint X and if i am going to update this is how i have allways done it with no issues at all.
you can leave your bootloader unlocked that is no a issue. but i always take OTA's and you cant take a OTA with a modded system. so i allways just flash my stock firmware package. that way it removes my custom recovery. Root, and all Xposed changes. Then i take the OTA and just reinstall TWRP, then SuperSU then what ever else you want.
this is the safest way i have found to update, the nice thing about Unlocked Sprint phones is we can easily Root are phones via TWRP and SuperSu.
just my .02 you can do it how ever you like but this is how i am going to do it when the OTA finally comes out if it ever does.
I flashed my phone with CyanogenMod13, completely not knowing what I was doing. I realized there were a few bugs on CM13 like my camera not working and things like that so I want to go back to stock Marshmallow 6.0.1 so I can have FOTA and a fully functioning phone. I know it was pretty silly of me to actually attempt this without consideration but could anyone help me out on getting back?
I have a Z5 Compact E5823.
Thanks.
Just download flashtool, stock firmware and flash it
btw. It's Xperia Z section, not Z5
Thanks man, sorry about the wrong section.
Will I be able to flash stock rom and receive OTA updates? My bootloader is currently unlocked.
I have already tried flashing before and I am getting random errors each time, with all drivers downloaded properly.
I flashed it with Emma last night and it took me to 5.1.1, and I cant receive any updates, so what am I doing wrong?
I want to go back to stock rom with OTA updates, although CyanogenMod13 was great.

Nope, OTA not working on unlocked bootloader, this can brick your phone
How can I lock my bootloader? Or do you think its recommended I keep the bootloader unlocked?
I just wanted to go back to stock rom for OTA updates thats all.
Many thanks.

Do you have TA partition backup? If no, it's not posible to relock bootloader

I don't even know what that is lol. I should've done research in advance before proceeding to unlock my bootloader. I did make a backup of everything though, I used a tutorial, I used TWRP to backup stuff, or something like that?
Also, is there no way to receive OTA updates now that my bootloader is unlocked? Will flashing stock rom not allow me to receive OTA updates?
Thanks for your ongoing support btw, really stressing me out lol.

Does anyone know if I can take the current Verizon software update From Sept 1st NRD90M.G950USQU1AQGL. I Will I be able to revert back to the original stock OS version with Odin if I update it? Does SamPWND work on this or any updated OS software. I would like to get an update to allow me to use Bixby voice, the stock Rom is missing that, is there any safe update to take.
Reason I ask is that normally you need to stay on the original stock OS or downgrade if there is ever a bootloader unlock method ever found. I tried looking for this kind of info couldn't find it. Usually there is a thread with stock roms with this info but I can't find any. Any suggestions?

I took the first 2 Ota updates and flashed back to original firmware without problems before I switched to unlocked firmware. Sorry for the late response.

You should have no issue doing so as long as they don't mess with the bootloader
