All I would like to do is get my (not unlocked, but un-rooted) back to a stock recovery (I think?) and a stock OS. I want to be able to do updates OTA as they arrive on my phone, and the only reason I rooted in the first place was to get Gingerbread from CM7 and they didn't work. It got stuck in a endless boot loop and once I finally got a nightly working, it wasn't even worth it to me anymore.
I have used this thread: http://forum.xda-developers.com/showthread.php?t=614850
and done hours and days of research to try and solve my problem and get me to where I would like to be. I'd like to think I am not a noob to Android but clearly I am and I can't achieve 100% of my goal.
Where I am currently: Stock image, not sure of recovery, unrooted, bootloader unlocked.
Where I would like to be: Stock everything (I know I cannot relock the bootloader) just like when I bought it, so I can patiently wait for Gingerbread to push OTA whenever Google solves the issues.
Thank you and I apologize.
That guide has pretty much all the information you need. Flashing the stock HTC images and stock recovery will enable you to get OTA updates.
Read my signature, find "Unroot/restore" guide, look for the part for unlocked bootloaders.
Clearly that did not work for me or I would not have posted my concern.
@Jack_R1 I will attempt this again, thanks.

You didn't explain where you got stuck, what you attempted, what went wrong and couldn't even state your recovery image. The guide you linked to is there for a reason, it works, however onlyif you follow it correctly without jumping in with 2 feet. If in future you require more precise help perhaps you should give precise information.
Perhaps the OP has encountered some of the issues i've posted about HERE?
Don't mean to kind of hi-jack this thread...
Don't mean to kind of hi-jack this thread but on the related topic of rooting the N1...is there some way to root it and still receive the OTA update for gingerbread(whenever it will come out)?
I did look through the threads and found nothing related unless it was further discussed on page x of 25, for example.
Also, are all wallpapers 960/980 by 800 for the N1 and other android phones? Is this so that when you scroll through screens you will still be able to see the image? That was the only possible answer I could think of.
Thanks in advance.

Yes and yes.
You can root using SuperOneClick and still recieve OTA updates. You only lose that ability once you've installed a custom recovery.
Thanks!

Having a custom recovery has NOTHING to do with your ROM's ability to receive OTA updates... it has to do with you ROM, not your recovery.
And, as mentioned, rooting or unlocking has no impact on you being able to receive OTA updates.

Uh, sorry, but NO. What he says in that post is incorrect.
I have been using a custom recovery since I first got my Nexus One, and I have received EVERY OTA update.
EDIT: But hey, don't take my word for it. Try it yourself.
efrant, for clarification, do the OTAs auto install, or do you have to manually flash them?

So, in my setup (which is a rooted-but-otherwise-stock ROM and Amon_RA's 1.9.0 recovery), I receive OTA updates, and they auto-install with no problem (as Amon_RA's 1.9 recovery does not verify signatures). Note, however, that every OTA update also does two things: 1) it removes the permissions on the su binary (which obviously disables root access), and 2) it copies two files (/system/recovery-from-boot.p and /system/etc/install-recovery.sh) back onto the system partition, which will flash the stock recovery back to your devices as soon as you reboot. You will need to root first (either manually or by flashing ChainsDD su update before you reboot, or use SOC), then delete the two files, then reflash the custom recovery you want.
This is true only for Amon_Ra's 1.9 and later recoveries that either don't verify signatures at all, or allow turning verification off.

Yes, you are correct for the installation part of the update. However, you can have any recovery whatsoever, and it will not impact you receiving OTA update notifications.

thanks for all the other responses to my question! I will look into this further when i have more time
Of course you can still 'receive' OTA but what's the point if you can't install them? I'm pretty sure that everybody understands the distinction!

Hey guys,I need some help here. I am currently complete stock rooted and everything is working.
But when I flash another ROM, I cannot get any phone calls. I am being told that my phone rings and rings, or just goes straight to voicemail. I never once hear the phone ring,on a custom ROM.
I have updated all my firmware to the tee. I tried reflashing the radio, to see if that helps, but nothing. When I restored my stock nandroid, everything works. I am a crack flasher,so this is killing me!!
I have looked over APN settings, asked people in ROM threads, and I think I am the only one. I know I'll hear, you are doing something wrong, but I really am not. I clean flash everything. 5.0.x and 5.1 ROMs, all result in a lose of getting calls. Data works fine. Texting even works. Calling out works! But I can't get calls. Please help /;
Have you tried turning off enhanced LTE setting in "more>cell networks"?
Yes, I have tried all the tricks. Just can't get calls to work .

I had this problem also, easy fix.
Settings/more/cell network/access point names (APNs)..... click on T-Mobile GPRS, just click it to open the settings, the where is says apn protocol, change it to ip4, click the 3 dot menu, save, make sure its ticked..... might have to flip airplane mode on and off, I didn't.

I will give it a spot. I did this too, but still no calls, but I will load up a ROM. I know that Sykpos said it's a known issue.

I have to do that for every rom I install. For some reason the apn is set to ip6, that is stock, but it wont connect. As soon as I set it to ip4, I have service, phone and data.

I had this problem too, it happens when you're using a 5.1 radio on a 5.0 rom, just flash the 5.0 radio, even if you're on the 5.1 bootloader.

Sorry for the huge delay. That did not help me /:
New radio,APN settings, everything. Only complete stock has calls working.
your issue has nothing to do with flashing the new radio. the rom you are using is based on aosp, and aosp is missing some lines of code that make you hear your speaker. flash the older radio again(not new radios), then flash this fix https://drive.google.com/file/d/0B-W-PFSvgML0Mm5NdHIyQjlPeXc/view?usp=sharing to listen to your phone when you make a call or receive calls.
Does that new E radio work with 5.0 roms and tmobile? You can receive calls and also hear them using the newest radio?
Okay guys, I can confirm that flashing a 5.0.x radio fixed my issues. I can get calls on 5.1 and on 5.0.x !
From what I have read, the radios (new) are causing issues on T-mobile.

yup, the radio itself is giving mamy tmobile users issues, as thats why i reflashed an older radio. if you have an issue with your 5.1 rom about hearing calls themselves (not getting calls, but hearing the person on the other line), then flash that zip i posted in the previous page.

So even the newest radio is still giving us TMO users issues? So I should NOT flash the new radio, but the new bootloader is OK?

shouldnt be an issue with the new bootloader, but im still using the older one as well. i dont flash cm, ever. so why do i need it? the old one works fine
I guess im just really confused about everything, is there any benefit to going to the 5.1 rom if we still need to keep the old 5.0 radio?

sure. mamy bug fixes, and a few additions(like if your phone gwts stolen, then wiped, you can still disable it).
If you didn't know the 5.1.1 update comes with a "locked" bootloader (G920T) that does not allow you to flash custom recoveries. I would like to know what your status is if you don't mind because I think the more people who are stuck like me the more developers will say we need to come up with a fix for flashing custom recoveries issue.
The bootloader isn't locked. Twrp just needs to be updated. Won't happen til kernel source for 5.1.1 drops
Did we really need another thread about this?
Edit: Please explain how someone "accidentally" upgraded from rooted 5.0.2 to 5.1.1

That is why I put "locked" in quotes and no I am not sure of that the phone blocks any custom recovery installed and I explained in another thread how cf-auto-root is just a recovery that is why it isn't working either.

I didn't make the 3 threads others did I just responded to all 3. Also the whole point of that one choice in the poll is for people who were expecting a normal tmobile update and didn't get what they thought they would usually tmobile let's you downgrade and you can flash a recovery right away but this time it was different and not a ton of people knew it was going to be different maybe I should've worded it better I am sorry.

I still haven't received the OTA and Marshmallow update, and am starting to wonder if something is wrong with my device.
I'm in England, my N6 is unlocked, my SIM is "3".
Is anyone else here still waiting for Marshmallow? Or can anyone offer any advice, please?

I do apologise. Your signature about XDA mantras was so huge that I actually missed your question above it!!
The answer is yes, it's 100% stock, unmodified. The only thing that may be pertinent is that I'm on the Marshmallow developers preview. I've had all three previews; numbers two and three came across over the air perfectly. There's just no sign now of the official build.

Many thanks for the help and comments, guys.
Yes, I bought the phone from the Phones Show Chat forum. So it was the previous owner who flashed the first preview build, not me.
I guess I have no choice, then, but to have a go at flashing the official build.
I'm not a complete newbie or an idiot, I'm confident that I can do it, but I would have preferred a step-by-step guide that doesn't presume any prior knowledge or experience. The one recommended by Jj14 still assumes a little too much for my liking. If I step a single foot off the correct path, I'll have no idea how to recover. If anyone can recommend another, safer, version I'd be most grateful.

You can find the factory images here: https://developers.google.com/android/nexus/images?hl=en#shamu
There are the instructions how to flash it, but ignore the last step of locking the bootloader. If something goes wrong, and can't boot it, you can have a nice brick in your hands.
Save all your data! The flashing process will wipe it completely.
There's not magic needed, just fastboot. Turn your phone off, press down and power, until the "Fastboot flash mode" screen comes up. Then follow the instructions.
A couple of things explained:
1. The bootloader for the M preview and MRA58K were the same, but the MRA58N one might be new. I didn't try it.
2. if you unpack the "flash all" zip file, you can do the flashing by hand yourself, you can skip userdata if you don't want your device fully wiped, but then you must do a factory reset.
And if something is not clear, please feel free to ask anything. It's better to be sure than being modest and have a nice brick.
Edit: The bootloaders are the same bit for bit as the preview.
And the three official packages 58k, 58n, and 58r have the same radios.
58n is the security patch it is noted in the AOSP source too, and nobody knows what 58r is, but it can be for Verizon. But I'm not sure.
Continued thanks.
Still very nervous and somewhat out of my depth, but here goes nothing.
And ... fell at the first hurdle!
Can someone please tell me which version I need; "MRA58K", "MRA58N" or "MRA58R"?
Always the newest. MRA58K was the first Marshmallow factory image. MRA58N is the 1st November securty update, and so far nobody knows what 58R is. People are guessing here:
http://forum.xda-developers.com/nexus-6/help/mra58r-build-t3242328
I found this excellent step-by-step guide, and followed it carefully. Result ... I now have official Marshmallow.

I'm stuck on LVY48I ( 5.1.1 )
don't know why it's too long to get the update !!
My Nexus totally stock.
Hey guys! So this is a very strange issue. When I power off my nexus, a lot of times I have to wait a good 30 seconds or so before I can power it back on or go into the bootloader. If I power it off, and try to turn it back on fast, it stays black screen almost as of it's frozen or just not responding. I noticed this issue begun when I flashed the radio from N preview 2, and didn't happen before that. My question here, is what could this be? Can the radio really cause odd things like this to happen? Or is there another cause? I am running the newest Android version MOB30I, and have multirom installed with about 4 or so secondaries.

the N radio, is the same exact radio that google released for the may security patch. so the N radio, is the latest official radio for the nexus 6. so no, that wont be the problem.

I wonder if it is. I'm using the newest Elite kernel for Marshmallow, it's always been my go to kernel. It's strange because after turning the device off, I can't turn it back on instantly, screen stays black as if it's not 100% shut down yet. I have to wait a bit before turning it back on, or entering the bootloader.

im going to guess, try a different kernel. as its the kernel that will boot up the device?

No, it's the bootloader that boots the device.
If he's hitting the power button and unable to get to the "Google" splash screen or the bootloader, the kernel is very irrelevant.
I'd be more curious if he's trying to use the bootloader from the N-Preview 2 with MM. Even though I think it's supposed to be backwards compatible, the bootloader is the only thing that would cause that sort of issue.
*technically* I'm pretty sure that you could format /boot (where the kernel is stored) and still get to your bootloader for fastboot and such. So, the kernel is really irrelevant until after the bootloader does it's thing.
*edit*
also, there's a reason that these are known as "Developer Previews" not "End-User Previews"... If you don't know how to fix weird issues that pop up like that, you should probably avoid them.

Mmm yes after what said simms22 I've check the n preview and the bootloader is xxx.18 instead of last mm which is xxx.17 but a bootloader downgrade is risky right?
@H4X0R46 do you use the .sh file and update your bootloader and radio with n preview?

It can be. Normally, once you upgrade, you just stick with the new one as they're backwards compatible normally. But, the ones for the Previews aren't always 100%. The whole reason these previews come out is so that developers can start making their apps compatible prior to the official release. Ideally, this is supposed to be done in emulators not necessarily real devices.
If the 30 second delay in powering back on is *that* big of a deal (to him) to risk bricking the phone by downgrading the bootloader and having something go wrong... I say go for it.

Is downgrading the bootloader really risky? I've done it before without issue and never knew this was risky! Are you supposed to just stay with the newest bootloader if you already flashed it? I always flash the bootloader for the image I'm flashing, even if I'm downgrading.

I flash each partition manually.

It's always risky when you're messing with essentially the lowest level software on the device. For instance, lets say that something happens while you're flashing the bootloader and it corrupts. What do you use to reflash it? You can't get to fastboot anymore...
As long as you know what you're doing, don't have corrupt images, and don't lose power or have lightning strike your computer while you're doing it, you would be fine.
The issue is that many/most people on XDA these days have no idea how to recover from problems or even what problems the things that they're doing might cause. So I tend to approach every situation under the assumption that the other poster may not have a full understanding.
No offense intended of course.

Alright so that's just to be safe then? My laptop sometimes freezes solid out of the blue, uncommon but does happen, and I always thought "what if I'm flashing stuff?" Scary thought. ESPECIALLY the bootloader! So the danger you're referring to is flashing a bootloader in general, not so much downgrading? Like I said, I always match the bootloader to the version I'm running. This is okay?
EDIT: I ALWAYS ALWAYS ALWAYS check the MD5 checksum for EVERYTHING before flashing. Can never be too safe

In general, the bootloader needs to match the highest version of android you intend to run. They're typically always backward compatible. On some phones, you can't downgrade the bootloader (at least not easily). This phone you should be fine doing so. However, there's not usually any reason to (backwards compatible afterall).

Cool! Thanks for your input on that! Much appreciated! Yea I'm always wary of the bootloader because like you said, it IS the lowest software on the device. Quick question, if that were to get corrupted, does the device just not boot resulting in permanent brick? Or does it boot just no fastboot access? Might be a noob question, but why not ask lol

Depends, I've never really looked into unbricking this phone. Never had to yet.
Depending on the phone you can use tools like QHUSB and similar which let you reflash partitions just through the USB connection.
I know it's late but it could also be just the rom setup. I know a while ago there were commits that shut the device screen and buttons off before it was done shutting down (to make it appear faster) this made devices seem bricked for a short period. I don't know what ever happen to those commits, so I can't say for sure that it is them. But your issue fits perfectly.
So have I been flashing the bootloader wrong all along? I flashed in twrp a couple times but I try to flash them individually and wipe after flashing.

Anybody able to find out why? I'm surprised to see I'm not the only one having this issue, it's annoying really.
