Hi, thanks for reading,
Ok so my 6903 z1, i've downgraded it to .534, rooted it, installed dualrecovery and am sitting here wondering where to go next.
I wouldn't mind unlocking the bootloader so that I could install other kernels such as pimped kernel. But reading the dualrecovery thread it seems that it is only if you are using the original kernel. So my main question is, what should i do next?
use recovery to flash a zip of a new rom then unlock bootloader then flash a supported recovery?
or should i unlock bootloader now and then new rom etc? (was concerned about the camera issue unlocking the bootloader on <4.3 roms.... will it be "fixed" if i was running on a newer "flashed via recovery" ROM?)
any help is appreciated as I don't want to bugger up the phone like i somehow managed to last time i tried all this (had the IMEI disappearing issue)
If you want to unlock the boot, there is was no need to downgrade to root
Just backup your TA, unlock the boot, flash a custom kernel of your choice then flash away
oh ok. well i've done it now. although I've just checked my service menu
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

and it says bootloader unlock allowed: No
So i'm guessing I randomly cannot unlock it anyway? (any reason why if that is the case?)

If that it saying then no way around to unlock your bootloader. BTW, stock kernel isn't that bad and with root you will be able to customize your room and get some tweeks.

so if i cannot unlock bootloader, does that mean i wont be able to use custom roms like Paranoid android etc which run off of CM and presumably a CM kernel?
and is it worth trying to unlock the bootloader in flashtool anyway just to see?
What options/next steps do i have then if i cant flash a custom rom due to not being able to use a different kernel?
Guess i can flash a modified stock rom and thats about it?

Unfortunately No, anything based on Custom Kernels you cannot install. Everything based on Stock Kernel you can Install, even Custom Roms.
oh bloody hell. ok so i'm now stuck in a sony logo boot loop after installing romaur v8 and installing the kernel (561) which it told me to.
any ideas what to do? guessing i'm going to have to flash the old 4.2.2 rom from scratch again
ok so now i'm back to .534 [nut] and rooted. any tips on where to go next so that i dont get stuck in another bootloop???

Just any Rom based on Stock Kernel.

I thought the romaur rom Was based on stock. Ho hum. Installed the pure stock one and it was OK thanks.
In Android developement thread all roms are based on stock - in original Android developement they are based on pure android.
Bootlooping is mostly caused when flashing wrong bootbundle/kernel.

Should I relock the bootloader after flashing M ?

NOOO!!!!
To many folks have encountered an issue that soft-bricked their device afterwards.
You will still receive OTA with an unlocked bootloader.

you can relock it (safer) but if you want to flash any new rom later you will loose all your data. cause everytime you flash you need to unlock the bootloader. its up to you

Hang on now, lets be clear about the advice that we're giving here.
Yes, a locked bootloader is safer if a thief were to get his hands on your device. However, locking the bootloader has a whole host of other problems linked to it. For example, if you end up in a boot loop with a locked bootloader because something breaks in the rom or kernel, if you have stock recovery, you can never unlock the bootloader again, without sending it for repair.
I would suggest people using experimental ROMs should keep their bootloader unlcoked to avoid this

If I did lock the boot loader, can it not be unlocked again using NRT ? I'm wondering since this (Android M) is an official release from Google, there should be a way to unlock the Boot loader if someone wants to roll back to lollipop ... Am I wrong in this assumption ?

It's a security feature whereby if you do not have "enable OEM unlocking" set in the rom, you cannot unlock the bootloader. If you don't have it set, have stock recovery then have a rom that will not boot, you cannot set that, ergo cannot unlock the bootloader. If you're going to mess with exxperiemental previews, I would suggest not re-locking the bootloader.

I just checked and the 'OEM unlocking' option is turned on under Dev Options.
So, can I unlock the bootloader and flash back to 5.1.1 ?

Hi All,
I want to relock my Bootloader on my Nexus 6 running Nougat N6F26U. Has anyone relocked on Nougat?

Hello... Why do you specifically ask about Nougat? Unlock/relock is not firmware dependant..
Something to read just in case you didn't find it when you searched: https://forum.xda-developers.com/nexus-6/general/guide-safely-lock-bootloader-android-5-1-t3067302
Good luck...

And why do you want to relock? Paranoid about security? Keep your phone in your pocket.
All advice in XDA is not to relock your bootloader because it reduces the possibilities of recovering if you ever make a mess of an update.

Thanks for the reply, I read it and didn't know if it would work on Nougat.

Just install a custom Kernel that "kind of" hide your unlocked bootloader. EX Kernel, Franco and some others will be just fine. Android Pay will work... I would never lock the bootloader of mine, except for RMA purpose. If something fails, you have way more chance fixing it..! :good:

Yeah don't worry, it's still a Nexus
RacerXO - did you get Android Pay to work on the N6F26U Build? I also cannot get the bootloader to relock. I tried using WugFresh Nexus Root Tookit v2.1.9.
Did you install a custom Kernal? Wondering if this the answer. Thanks for the help.
I was unlocked from the first day I got the phone. Today I am locked, running nougat. Having read some of the horror stories here, I've always booted the phone after flashing updates before rooting. Did the same thing when I went back to stock to use AP. I backed everything I wanted to keep and made sure it booted, before I locked the bootloader. No issues after almost a month.
What I wound up doing was go to the T-Mobile page and established the official latest factory image was 6.0.1 MMB29K - installed that using Wugfresh. After installing and logging into WiFi and my Gmail account was prompted to install 7.0.0 NBD92G - this installed fine and then after installing a couple of security updates (thru April 2017) was able to Re-Lock my Bootloader (I wanted Android Pay to accept my credit cards). Data reception is still degraded significantly, am now thinking there is a problem with the tower.

Rooting with Magisk then using Magisk manager to "hide" root should give you android pay again. This may not be the directing you want to go in, but it is an option.
I locked Bootloader but you have to flash stock recovery 1st
I was on stock 7.1.1 unlocked bootloader, rooted Nexus 6.
I relocked my bootloader by simply going into adb/fastboot and flashed the latest stock factory firmware image (not the ota) with the June 5, 2017 security update, rebooted, activated developer options and enabled usb debugging, adb/fastboot again, and entered the command "fastboot oem lock", hit okay/yes when I got the relock warning, and voila! phone relocked.
Rebooted and set up phone/reinstalled my apps, music, and files.
No issues.
Say on stock I ticked it to unlock, flashed twrp, flashed rom, everything is great. Will it relock itself after the rom flash or will the option just disappear? Thanks.
Don't do that
You might get oem jail if you do

depends. once unlocked it would stay unlocked. but if that option was hidden for 7 days and then appeared, it might disappear if flashing a new rim or firmware or wipe and not allow you to boot and force you to flash back stock a d wait 7 more days before it appeared.
i believe rom devs are well aware of this issue and are 'baking' in the fix in their roms.
i know that back on the note 8, the famous OEM unlock issue was widespread. on the note 9 i am not sure if this is still problematic.
