When I received my device 1 year ago, I checked to see of the oem unlock switch was greyed out. It was not at the time and the phone was not branded. I bought it through Xfinity, so I popped in the sim card and started the activation. I know its normal to download branded firmware, but it locked everything. It has been about 6 months since I bought a new phone and Xfinity's garbage firmware is still locking up my pixel. ADB fastboot fails at bootloader unlock. I went online to check my devices and they have removed my Pixel from my devices list as well. Is there a way to sideload the original unbranded Google firmware without unlocking the bootloader? Any ideas would be greatly appreciated!
There is only one firmware for all variants of the Pixel series. While some carrier software may install when the device detects a carrier SIM, the firmware is not carrier specific. The only difference is the occasional modem updates that might contain various fixes and improvements for specific carriers, but this does not affect the system image. If OEM unlocking was available before you connected to the Internet, that was probably your one chance, as sys.oem_unlocking_allowed is set by means of checking the IMEI against an online whitelist.
To make sure I understand you correctly, are you trying to unlock your bootloader or not? If you bought it through Xfinity instead of Google, it might be subject to carrier rules on OEM unlocking.
Am following. Tho I already have arooted P6a from google, I'm considering switching to Xfiniry cuz I'm already a broadband subscriber. Still on the fence tho...Verizon's not too bad...

Hi Forum. May be my first post. I just SIM unlocked LG V10 on T-Mobile. Here is what I can say about the process that might be helpful to others:
1-Phones can be SIM locked by manufacturers so that service providers ensure that phones can only be used on their network or certain countries. See https://en.wikipedia.org/wiki/SIM_lock for more information.
2-The process of unlocking requires the service provider to request unlock codes from the manufacturer. The service provider may have requirements to unlock ( e.g. in my case I had to put $100 balance on T-Mobile prepaid card ). This process took 5 working days at which time T-Mobile emailed me to inform me that they were ready for me to initiate unlock on my device.
3-On my device, I ran a "Device Unlock" app which connected with somebody ( T-Mobile ? ) and verified my phone was actually unlock eligible and viola. I'm SIM unlocked.
What I would like to know is what has changed on my phone ( e.g. firmware, some information on some partition ) ? Does this mean I can now root, change ROMs and my phone will remain SIM unlocked ? Any links to information about what actually happens when device unlocked would be appreciated.

What I can tell you is that, if you did unlock permanent it is going to be unlocked even after rooting and installing new roms etc.
Now, I want to ask in this forum if the phone can be unlocked if the t-mobile unlock app says it is not eligible to unlock. I bought my phone on eBay, called t-mobile the phone is clean, but they could not unlock it for me because needs an account... So now I'm stuck trying to find a 3rd party unlock website to do it, 2 already said they could not... So I have the phone but can't use it. Any suggestions?
Yes, I can confirm that on this LG V10 having performed a SIM unlock and then having switched ROMs the unlock remained in effect.
Hi guys,
I just need some general direction here.
I recently purchased a locked Sprint S9 Plus and I had successfully flashed the firmware to the unlocked version of the phone (Model number showing SM-G965U1 )
I had plugged in the sim card to the new phone, only to receive a message that says "Invalid Sim card." I also checked the system apps and it looks like there are some Sprint apps still on the phone. Any ideas?

You got confused about what "unlocked" means in various contexts. It's easy to do. The U1 firmware is for devices that are sold as "factory unlocked" from Samsung, Best Buy, and Amazon. But what that really means is "unbranded and unlocked". By flashing U1 firmware on a Sprint (SIM locked) device, you now have an unbranded device, but flashing U1 firmware cannot SIM unlock it. Those are different things. You still need a proper SIM unlock, regardless of what firmware happens to be running on it.

Wow, and after 2 weeks of research - I thought I had it all together.
I've looked up a few options to SIM unlock the phone. They seem to be:
1) root the phone, then sim unlock it (is this possible?)
2) get a sim unlock code (any recommedations?)
OR
3) get a new unlocked or carrier-specific phone
Anyone have inputs for options 1 or 2?

Can't discuss such things on XDA. Your carrier should unlock for you once you've met their requirements.

Unfortunately my family was going through a carrier switch where I purchased the phone before they changed their minds to go with Verizon. Now I'm stuck with a Sprint phone while my family went with Verizon.
I would gladly guidance from anyone, through PM or through this post, and is MUCH appreciated. Thank you in advance.
I'm looking at picking up a SM-G965F/DS (FACTORY UNLOCKED) for use on the USA T-mobile network. The one I'm looking at is reportedly Region free (no region lock) and SIM unlocked. . So a couple of questions:
1 - Should I be fairly safe in my ability to bootloader unlock and mod this version of the phone as described above?
2 - To get the OEM unlock will I use my t-mobile SIM for 7 days to make OEM unlock available or will the date hack work:
How to fix the missing OEM Unlock button on the Samsung Galaxy S9/S8/Note 8
3 - I'm familiar with unlocking and installing on older devices such as the OnePlus One, and Nexus series of devices. Is the process for the S9+ fairly bulletproof like those devices? I mean, they were all pretty forgiving to a little "Oops" here and there. No one needs $700 brick.
Received the phone today. Cannot get OEM Unlock to show even using the above mentioned method. Anyone have any luck to share on the this model #?
Did you ever figure out how to get the oem unlock fixed. I just bought a Claro s8+ sm-g955f and no matter what I try the oem unlock remains missing in my developer options
Hi,
I'm not unfamiliar with rooting/unlocking/flashing phones at all, but everywhere I turn there's a roadblock for this one that I can't seem to get by. I've never owned a carrier branded phone before so maybe there's some extra software lock that goes into the devices?
First off, let me state my purpose, which is to flash my ATT branded S21 with an unbranded firmware and/or to root and remove bloat.
1. Trying to flash with Odin multiple U1 XAA firmwares will cause a SHA256 error. Can't test with ATT firmware because ATT doesn't release it.
2. Fastboot won't detect my device in Download mode, selecting "Reboot to Bootloader" in recovery goes to normal boot. Tried Google drivers, Samsung drivers, no luck. ADB detects in sideload mode. Can I repack a firmware into a ROM and sideload it?
3. OEM Unlock is completely absent from Dev options. Tried the time trick. No dice.
Has anybody else done this to an ATT phone?
There is no OEM unlock option on any of the US phones, however to get the U1 firmware to flash you need to download the patched ODIN from here. After that it won't give you anymore SHA256 errors.
Make sure the firmware you download has OYM in it, not OYZ. You can see what I mean here.
OYZ will flash the Thom Browne firmware, which you most likely don't want.

Holy HECK. I knew it was something stupid and simple. zimgir124 you're a saint and I really hope somebody finds this thread useful in the future.
I was this close to returning the phone. Welp, looks like I'm a Samsung guy now. Time to tip that ODIN guy.
I may be in the same boat as I purchased an S21 from Samsung.com with ATT firmware. It is carrier locked to ATT and neither Samsung nor ATT are capable of unlocking the device. ATT claims they did not receive an unlock code since the imei is absent from their database. Samsung claims they send unlock codes automatically to carriers at time of manufacture but that they are unable to provide individual unlock codes post manufacture. Is it possible to flash a carrier locked S21 with U1 firmware to have an unlocked device? This might be a better option than going through the headache of an RMA.

No it don't work like that. Must be unlocked through company or any legit 3rd party service
I would like to get the oem unlock option on my t-mobile z fold 3. Is this possible after flashing u1 firmw?
I'm just about to return my Samsung A52 5G after realizing that the bootloader seemingly can't be unlocked. I did a quick google and thought it was possible, but apparently the North American version is locked.
Now I'm looking at this phone as my next option. Can anyone confirm if the OEM Unlock button appears in the Canadian version of this phone? I'm buying from the OnePlus website, and it says that it is carrier-unlocked (not T-Mobile).
I'm not even planning to root the device or do anything advanced, but I want to have the option to install Lineage later on once I stop receiving OTA updates, assuming that the Lineage devs make a build for this phone.

I believe there's a method to unlock the T-Mobile US version. I asked OnePlus's support, and there was a separate set of instructions for T-Mobile, so they might be able to help you.
I ended up buying the carrier-unlocked phone in Canada, and everything worked out; the OEM Unlock button wasn't blocked or anything. You just need the fastboot and adb drivers for the device, as usual.
There's a way to get oem ungreyed,read aroud
Even OEM and SIM unlock are separate, you have to have SIM unlock first before enabling OEM unlock.
Units sold directly from OnePlus.com is SIM unlocked.
