Unlocked Bootloader/Unlocked Phone?

Im planning to buy an unlocked version on the nexus straight from Google.com. My question is since its going to be an unlocked version does it mean it will also have an unlocked bootloader?? I know I need to unlock the bootloader so I can root and eventually install ROMS. Also, is it true that IF i need to unlock the bootloader GOOGLE will void my warranty?
Help is appreciated.

The bootloader is not unlocked out of the box however once you have fastboot setup it's easily unlocked with one command while in the bootloader.
Yes. It voids your warranty.

So although its an unlocked version still the bootloader is locked? Maybe Im getting confused between an unlocked phone and an unlocked bootloader. No relation?

Unlocked phone = not SIM locked to any particular provider.
Unlocked bootloader = you can flash whatever software you like on the phone = void warranty.

Great I guess that answers my questions. IS there a way to reverse it back to the Google locked boot-loader in case I need to return?

At the moment, no.

this should amuse you...
the $530 "unlocked" phone from Google is Sim unlocked...but so is the $180 TMO phone from Google For kicks I put my ATT Sim in my friend's TMO N1 and as expected, it worked just fine on ATT.
Not sure why they are calling it unlocked since all being sold are unlocked (unless my friend magically received the wrong phone) but I guess if that helps move units...why not. Perhaps they mean you are not locked into any contracts by purchasing it

yea that's wat is meant....

Even the subsidized version from Tmobile is not sim locked. Same phone, just get it at a cheaper price.

The "version" you get for $180 is the exact same one you get with $530. No one ever said it was locked. What they are doing is for the $180 price, you are re-locking yourself into another 2 year contract with T-Mobile and getting the phone at a subsidized price.
Unlike the phone they sell in the stores, this will be SIM unlocked since it is NOT T-Mobile branded.
T-Mobile (as well as any other carrier) will see this as a "gray market" device and will not support it, although, they will allow it on their network.
Hope this clarification helps.

Do unlock codes allow bootloader unlocking?

I currently have a rooted AT&T Moto X. I want to be able to unlock my bootloader so I can install other ROMs. My question is, if I purchase an unlock key from one of the sites on the Internet, will this allow me to unlock the bootloader? ... or is this just a SIM unlock? Is it maybe possible to bootloader unlock my AT&T phone without purchasing an unlock key? I've looked but I've yet to run into any documentation that says I can.
Much thanks for any help.

i'vve seen no sites selling bootloader unlock codes for the Moto X. (Other than that Chinese site/middleman deal)
What you are seeing are likely only SIM unlock codes for sale.
The info/thread on the Chinese site/middleman being back is the only way to obtain a bootloader unlock code for the ATT X.
There is no way to unlock the bootloader without the code.

Does unlocking the bootloader also unlock the SIM? I'm on Verizon, it doesn't seem like I've ever had to manipulate a SIM card in anyway. Is it because CDMA carrier don't use it?

Unlocking the bootloader and sim unlocking are two different things.
Unlocking the bootloader allows you to flash/install unsigned or 3rd party supplied parts/partitions (like recovery, modified or custom roms, etc), and that in turn allows you to easily root. Motorola gives out the Bootloader unlock codes for the Developer Edition X and some carrier editions (like T-Mobile and Sprint). For ATT and Verizon (non-developer), Moto does NOT give out the codes (likely due to carrier's wishes). No one has cracked the bootloader lock on the X yet, so to bootloader unlock the Verizon (non-Dev) and ATT X the Chinese Website/Middleman selling the bootloader unlock codes is the only way you'll be able to do this.
SIM unlocking allows you to use the SIM from other carriers in your phone.
Phones that are purely CDMA/EVDO only, like the HTC Incredible, Original Motorola Droid, etc, do not use a SIM and therefore there is no "SIM" unlocking for them. Those phones have an ESN burned into them. The carriers only accept ESN numbers of phones which were made for them (couldn't take a CDMA/EVDO phone from another carrier and use it on Verizon because VZW wouldn't allow the ESN). Verizon's phone's started using SIM slots when they added GSM Global Roaming to phones like the Blackberry 9930 and such. They were sim locked to Vodafone (Verizon's international roaming partner). They could be SIM unlocked for global roaming by calling Verizon's international department directly and requesting the SIM unlock code. Usually telling them something like "I am traveling over seas and I want to use a local pre-paid SIM when I get there), can I have the SIM unlock code for my phone?" would get you the code.
With the introduction of LTE, Verizon is using SIM cards for both LTE and GSM. Verizon's LTE phones are SIM unlocked due to the FCC rules around the 700Mhz C block auction they won years ago. The Moto X, Galaxy S4, Galaxy S5, and others are all SIM unlocked right out of the box. Other carriers like ATT and T-Mobile, ship their phones SIM locked, so to put a T-Mobile SIM in an ATT phone, you need to SIM unlock it first. The exception being something like the X where T-Mobile doesn't sell it directly, Moto does, and ships a SIM unlocked version with a T-Mobile sim.

It depends on what you want to do with your phone.
If you want to root no matter what RW pushes to your phone, and you don't mind voiding your warranty... then yes.
I don't have RW, but from what I understand, their Bootloader is locked, and like with Verizon and ATT, Moto doesn't give out the unlock codes for RW. So your only choice is the 3rd party Chinese website/middleman.
There is a thread for RW, and what can be done while the bootloader is locked. Its pretty much the same as VZW and ATT users... if you have 4.2.2 or 4.4 on your phone you can root and disable write protection by using SlapMyMoto/MotoWpNoMo processes, and if you want to run 4.4.2, you can make use of Safestrap (assuming your phone is still on 4.4 or lower to root it). BUT if you already have taken the 4.4.2 update, or flashed a 4.4.2 SBF, you are stuck unless you can unlock the boot loader.

I did motowpnomo and disabled wp. I have 4.4.2 update with root using this guide
http://forum.xda-developers.com/moto-x/general/guide-republic-wireless-moto-x-kitkat-4-t2738233
What I want to do is to get rid of this error message "com.motorola.process.system" ? I did everything I tried on google search.
safemode,
date&time
cache & dalvik cache
But one thing I have not done is factory reset. I am unsure I can do that to keep my root on 4.4.2. That is why I'm asking if I do bootloader unlocked, even if I screw up and lose my root or not, I will still be safe with root after because I have bootloader right?
Or if you can help me with any further information you seem to be very good in this area.

That is rooting, then using Safestrap to make use of 4.4.2... its more involved than unlocking the bootloader and rooting.

I don't use safestrap so I don't want to advise you, and possibly get it wrong.
I can say that once you unlock the bootloader, you can just flash a custom recovery, boot to the custom recovery and install SuperSU to gain root. This can be done no matter what rom is on your phone, even 4.4.2. You can factory reset, flash an SBF, take an OTA and still be able to root it. (of course some caveats apply in taking an OTA see -> HERE) And you can flash a custom/3rd party rom if you want too.

Carrier unlock a G920T permanently

Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!

The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock
Sent from my SM-G920T using Tapatalk

Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.

If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.

I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters

i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.

With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?

I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.

Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

Got it done remotely!

I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!

I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.

Please help

What do you mean by unlocked. There bootloader unlock and sim unlock. Sim unlock just allows you to use another network. Bootloader unlock allows to to flash. Also there is no Verizon firmware to flash because the Verizon model can't be bootloader unlocked which means you can't flash it. Verizon and att are notoriously the worst when it comes to having there phones eligible to be bootloader unlocked

I guess it's SIM unlocked since I can pretty much use it with any carrier by swapping the SIM card. I bought the phone new and unlocked from Republic Wireless and am trying to get it working with full features with Verizon Prepaid. A couple of folks on Reddit mentioned that I could flash the phone with Verizon software in order to get it to work as if I'd bought the G6 from Verizon.

Do I lose my already carrier unlocked code if I flash to Unlocked Firmware

So this may seem a bit of paranoia I may have but I already got my device unlocked from T-Mobilw but wondering if I flash the Unlocked Firmware (N950U1 from N950U) and then to Android Pie would I lose my carrier unlock that I already got unlocked from T Mobile by doing so. Also would Carrier to Unlock Firmware break the device?

No you won't lose it because it goes on a spot in your phone that doesn't get touched or erased when you change firmware or whatever. And no your device will not break however if you're wanting to try Android Pie there's one for the N950U1 version out now so you don't have to go all the way back to N950U.. Directions are on the forum already.

The carrier unlock is done server side at T-Mobile. Once it's unlocked, it's unlocked. Period.
