Nexus 6 Cyanogenmod carrier ROM ?

I looked on Cyanogenmod's website below:
https://download.cyanogenmod.org/?device=shamu
and it just has 1 ROM for Nexus 6. I have Nexus 6 for Sprint. Is there only 1 version of the ROM that works for all carriers ?
My old Galaxy S4 has many different builds for Sprint, ATT, Verizon, etc.... wasn't sure if Nexus has the same set up.

Yes, applies to all N6 variants.

thats because every sgs4 has a different setup for different carriers. we only have one nexus 6, and its the same for every carrier.

I didn't have a locked bootloader with Sprint Galaxy S4. If I were to restore the Nexus 6 back to stock to do an OTA update to update everything, then re-root and put a new custom ROM does the bootloader need to be re-locked, or can the factory .img be suffice to do an OTA ?
I'm still trying to learn how to do this as it is much different than the Samsung GS4. I saw there is a Nexus Toolkit by wug fresh. Is there any benefit to doing these processes by adb vs just using this progra which seems easier ?

you dont use adb for it, you use fastboot. and doung it right vs a toolkit.. toolkits dont teach you anything, and can mess things up.

Does the bootloader need to be locked to do OTAs or does the stock ROM with leaving the bootloader unlock suffice for an OTA ?

bootloader can be locked or unlocked, it doesnt matter. but i recommend that you keep it unlocked forever, as it can save your phone in certain situations. and having it locked can be the end of your device, in the same situations.

Ok. That's what I was planning on doing once it becomes unlocked. I was going to have it set like my previous GS4 and just toggle custom ROMs from there. When you mention having it locked, are you referring to when people have re-locked the bootloader then had an error flashing the stock custom ROM thus bricking the phone ? That's what worries me. Looks like the security is more stringent on the new Nexus vs. older versions.

i was actually refering to it because of the unlock setting that has to be ticked to unlock. some stock users got caught in a bootloop, then cant boot up to tick the setting, to fix their bootloop. since it cant get unlocked, their phones are a "brick".

Since the stock rom did not have developer options "checked" then the bootloader can't be unlocked ? How can you tick the OEM unlock if it is in a bootloop ?

Ok that makes sense. What is the purpose of having the bootloader come locked in a stock phone then ? What does it actually do ? Prevents root ? I probably took it for granted mine was always unlocked before so all I had to do was worry about flashing the proper carrier ROM

Security.

Security in that if stolen your phone cannot be made to work for someone else...
Someone can (and likely will [emoji14]) correct me if I am wrong... But does little to secure your data...ESPECIALLY if you stay encrypted.

It does nothing to secure data from remote access, but it will protect data (if set with a password) from physical access, providing they do not know the password. The bootloader being unlocked, with no password on encryption would allow them to flash a custom recovery and pull the data off. This will be decrypted on the fly. So it works in conjunction with Encryption. To secure data from physical access, you need both.
IF your bootloader is unlocked and you have no password, you may aswell not be encrypted

Nexus 6 unlock bit reset possible?

Hello Folks,
I have already managed to reset the tamper and unlock bit on my OnePlus Two.
So i just bought a Nexus 6 and i am wondering if the unlock bit reset is possible here.
The Nexus 4 and 5 had a unlock bit in the "misc" partition.
I read somewhere that the Nexus 6 has some counter-measures against this kind of tampering.
Has anyone already tried it?
I can provide dumped partitions as i am already rooted.
I am hoping for a good Discussion

There's a tamper ? I wasn't aware. Just the lock logo on the splash screen when the bootloader is unlocked.

Oh sorry i made a mistake there, i meant the unlock bit, if i relock the bootloader the logo still appears right? so the bootloader will still show that it was unlocked or will it be in factory state?

There's not a trip tamper like Samsung's knox. You just unlock the bootloader and there's a lock logo. It also says unlocked in the bootloader screen. If you want to revert back you just relock and everything is as is. Google's Nexus is really the only device that is very open like that. Other devices and mfg. you have some kind of permanent trip.

Okay Thank you, I did not have a nexus device before so thats great.
I received the device unlocked because it was used by someone before so i thought it was locked and was showing the lock anyway. but just checked the bootloader and it really was unlocked. So thank you

By the way, Google may have modified their software, but I'll say it anyways.....whatever you do, DO NOT lock your bootloader without having OEM unlock checked first even if you are restoring to stock. There are many threads here where users have locked their bootloader then effectively brick their device. Make sure you have OEM unlock checked prior.

Having USB Debugging enabled would also be useful in case of a problem with the device.

OEM Unlocking Greyed Out?

Perhaps I am just misremembering, but on NBD90Z, if your bootloader is already unlocked, should the developer option for OEM Unlocking be available or greyed out? Mine is greyed out (Pic attached) and only becomes available if I flash a 6.x ROM.
Tinfoil hat backgrounder....
I recently wanted to verify my carrier unlocked status on my Nexus 6. I popped in the Verizon SIM from my recently purchased Pixel, which worked fine. I'm now worried that however Verizon is able to force OEM lock onto the Pixel has now been set on my N6 and if I relock I will be unable to unlock.

@mattfrazer,
Yes the option is grayed out on 7.0 if your bootloader is already unlocked. I'm on Fi, my bootloader is unlocked, and it's grayed out on my N6.

No carrier to my knowledge can force lock a bootloader. Once you fastboot oem unlock it, it will stay that way till you pass the fastboot oem lock command.

I understand that. My worry was not that lock would be force enabled, but that the option would not "ungrey" if I were to choose to lock the bootloader on my N6 again. Either I hadn't paid close enough attention post 7.0 upgrade, or hadn't gone through the 2 step unlock process since running 6.x to notice the option greys out if your bootloader is unlocked on 7.0. I must not be the only one as the description under the option is changed in 7.1 to say "Bootloader is already unlocked" instead of "Allow the bootloader to be unlocked"
Thanks again to you both.

there are 2 possibilities . 1 : your bootloader is already unlocked(check it by going to fastboot) 2: turn on USB debugging ON
im sure your bootloader is already unlocked
cheers

Thats a good question. I have been away from VZW for a while now but did they have an N6 branded to them? if so, did they removed bootloader unlock like they do with HTC phones branded to them? if you did buy one from google or a non branded N6 carriers have zero control over it so in theory you can lock and unlock the bootloader at any time regardless of the carrier you are using for cell service. I personally never had to go back so i never noticed the greyed out option.
But thanks for pointing this out.

It is gray if you are already unlocked so you dont hit that before you fastboot lock if you are relocking. Doing the slider first can be bad. It was a changed in N.

No, there wasn't a VZW branded N6. In the US, only AT&T had a branded N6, and FWIW it was carrier locked to AT&T. Usual rigmarole to get it SIM unlocked. This version had an unlockable bootloader, just like the Google Play Store version.

So we can simply lock it again, without having to tick it or anything?

Yes there was. Vzw was the last of the major carriers to pick it up though.

[Sprint] Unlock Bootloader?

I know the Sprint bootloader is locked, but does anyone know if there will be a way to work around this?
I have seen some threads on a trick to unlock the Verizon bootloader even though it also comes locked- would this work for Sprint? Thanks
UPDATE: What is the Pixel version of MSM/ODIN? I know how to get to EDL mode on it, but from there how would you go about flashing a different firmware to potentially get around the bootloader? Anyone know?

Need Help with bootloader unlock

I bought a new Pixel 4 xl when I tried to set it up, it gave me a notification " Your device is managed by your admin". I tried to enable OEM unlock but it was grayed out. I updated it to Android 12 beta I don't see the notification anymore but still can't enable OEM unlock nor even unlock the bootloader.
I want to unlock the bootloader is there any way to do it?
The phone is carrier unlocked it accepts every SIM card on both Physical and esim.
Thanks in advance.

Are you sure it's not an unlocked Verizon or T-Mo 4XL? They can be carrier unlocked but still be bootloader locked and I'm not sure if there's any way to tell by the model nbumber or IMEI.

Hmm there is the IMEI will have VXN on it or the serial number will probably show it and such has it
It probably lies in the about phone settings

Just as an aside, I got my 4 XL from T-Mo when they had a sale and couldn't get the bootloader unlocked, but the Soli chip went bad under warranty, so when I sent it back to Google, they sent me an unlocked (both carrier and bootloader unlocked) replacement.

No, I started with a T-Mo oem locked, but Google sent me back an oem unlocked replacement.
My Soli chip went bad after just a month or two.

Because you are BL locked the only two things you can try are a factory reset from recovery, and flashing a full OTA from recovery via adb. If that doesn't work, I'd be trying to get my money back.
Since your IMEI is permanently stored in a school or company database, the admin error will likely return when the device phones home (at first boot when wi-fi is enabled) and from the sounds of it, a policy has been set to prevent bootloader unlocking. That phone may be new to you but it is likely black market.

Now I understand the problem. I have tried the reset option and full OTA update in Android 12 the error isn't here anymore but OEM unlocking can't be enabled.

Yep. Looks like you were ripped off and will never see the full benefits of having an unlocked phone. Since it was "new" I would be getting my money back.

Oh thank God I came to know this before I buy the phone for myself. The problem is actually happening in my Uncle's phone.

Might have the Verizon variation
