[Q] Bootloader Unlock on Sim Unlocked Rogers XPlay

So it's common knowledge by now that the Rogers Xperia Play cannot be bootloader unlocked due to the sim lock on it. I recently bought one and Sim Unlocked it for use on the Fido network.
Is there anything else stopping me from using the bootloader unlock or am I safe to do it now?

*Edit* sorry i didnt read your OP well, You have to have a factory unlocked device from the start, you cannot just sim unlock a branded device and get an unlock code sorry

I have mine sim unlocked but as far as I know I still want unlock the boot loader.

[Q] How to know if my Nexus 4 has already an unlocked bootloader?

First of all, sorry if this has been already asked in the past, i didn't find any thread for this so far.
Recently, i bought a LG Google Nexus 4 from the British amazon, the seller was saying that the device comes unlocked (which means that it can get any sim from any other network provider).
Furthermore, i want to root my Nexus 4 device and i have seen the steps. One of them is "Unlocking your bootloader".
So, my question is how do i find out if the bootloader for this device is already unlocked so i can skip this step on rooting?
Thanks in advance.

When you boot up the Google logo will appear and underneath there'll be an unlocked padlock if the phone's unlocked. The likelihood is that it'll be locked though.

locked and unlocked bootloader

I wanna share my experience with my locked bootloader.
I tried once to unlock and install a "just 4 unlocked" rom (2 roms actually) but the radio system didn't work (no phone, no wifi, no gps).
I got back by flashtools, i installed a rom 4 locked rom and i tried once more to unlock the BL. I installed CM10.1 and now everything is working perfect!!!
I got just a question 4 you: why does some xperia z has the BL locked while others unlocked?

All Xperia Zs come locked from the factory. Most can be unlocked to flash custom roms. Some are permanently locked because their carriers are iffy (to put it nicely), but those are the minority.

Keep Questions in the Q/A section, not in General.
And No SONY device comes with locked Bootloader always. All are locked by default from the factory. Among which some can be unlocked and some can not because the Carrier.

Ok, but my gadget showed "no in Service info > Configuration > Rooting Status > Bootloader unlock allowed (and in the post about unlock BL they says that if it's "no" the device cannot be unlocked).
Thank you
PS: How can i move the 3d to Q/A ?

That is what I said.
All the Devices are locked bootloader by default.
Bootloader unlock allowed= Yes -- This means you can unlock the bootloader by following regular method.
Bootloader unlock allowed= NO -- This means you can not unlock the bootloader. Because of the Carrier issue i believe.

thx i got it.
But mine showed Bootloader unlock allowed= NO but i was able to unlock it after 2 try. I think every one following my procedure might do it.

I think you will always have been able to unlock yours, you just didn't do it right the first time.

So are you saying you have a locked boatloader and can install. CM10????

did you root it and put a different ROM on there? the status might change say no but you can still unlock it. Simply put if first time you boot up your phone and it say Unlock bootloader = NO, then dont try to unlock it. When you root and flash a different rom that status might change to yes but in reality it still a NO

Eventually a right answer.
I was told the same. But i love to risk "playing" with my gadgets. So when i bought the xperia z through a carrier I saw the first time i boot up that the phone Unlock bootloader = NO (about 5 minutes after i bought it from the shop, so it was "original as the carrier made it).
I didn't care it and i tried to unlock. I installed a unlocked bootloader and rom and i had all that problems with the radio stuff . But the second time, after i recovered it by flashtool and a sw from sony (i don't remember the name) I was allowed to unlock it and install unlocked stuff. Now I am with Paranoid and I am so happy

same here... unlock it. install all the unlocked stuff. Radio might don't work. . Get ur phone back by flashtool and sony sw (i don't rememmber the name). The sony software will say u after a while u r not able to recover the phone cuz you are using some some software that is not sony. Don't worry and install another time a rom unbranded by flashtool.
now unlock the phone again and install everything u might like
There is only a problem with the twrp recovery, so use only the other one

Can anyone else confirm this?
Thanks!

Very interesting... Im waiting the confirmation from sony to pick up my phone without cost to change the fastboot to yes, but if this is true and someone else could confirm this method il do it tonight!!!!

I think if you want others to try what you've done, (and it is interesting if we can unlock bootloaders this way)
then you may want to highlight which steps you did in more detail.
Which roms did you try to flash that resorted in no radio functions?
which rom did you try to flash with flashtool? which version of flashtool as well?
Did you do anything else?

I somehow doubt engineers would make an oversight as big as this one.
But fingers crossed nevertheless.

+1 for a detailed description of the steps you took. This could be huge!

Indeed, this move would make the XZ much more attractive for buyers which have the bootloader locked from the carrier.

Nexus 6p nougat bootloader

I have a major problem, I need to know if it will be possible to flash a custom rom on a nexus 6p. It seems that it will be hard because of that new bootloader.

What do you mean? Any bootloader version on this device can be unlocked.

Sorry, I'm new to this stuff. I thought they can change the bootloader when you upgrade. Thanks for the help though

The bootloader does get updated. But you can unlock any bootloader, and updating it doesn't lock it again. Take a look at my guide:

Oh, because i was afraid of the phone won't boot because of the android n won't boot if the phone has a unlocked bootloader.

Nope, nothing like that to worry about. The locked/unlocked status won't stop it from booting.

Thanks. I can now upgrade in peace

ATT VoLTE and relock bootloader?

Before I get this phone. Does anyone on AT&T know if they white-listed this device for VoLTE?
Also, can we re-lock the bootloader like Nexus Devices or once the bootloader is unlocked it can never be re-locked again?
Thanks

You can relock the bootloader if you want to unroot and return to stock.

Thanks I posted the question there..as I did not get a definitive answer. When I say relock, i want the behavior like the Nexus phones where it will do another wipe after the fastboot lock and fastboot mode shows correct lock status. Used to have one plus 1 and once unlocked you could never relock the bootloader..

AT&T only supports VoLTE on AT&T branded phones. So unfortunately, no.

par for the course w/ that company. I think they have taken the mantle from Verizon as being the biggest jerks. If it wasn't for their iPhone business, they'd be sunk. They have done a fabulous job of raising the prices of all things DirecTV too. ugh.
