Hi Folks,
I have an HTC one m9 which has originally been locked (S-ON) by AT&T. I bought the phone here in Canada. I wanted to update the phone with the latest Android update. After facing some difficulties, I successfully updated the phone to latest ROM ( 3.38.502.41) before Android 7.0 Nougat 4.27.502.7. Long story short, In order to update to 4.27.502.7, I tried both RUU and OTA zip methods using "fastboot flash zip ", "adb sildeload", but due to S-ON, I could not achieve my goal.
I contacted AT&T folks and they generously gave me the "unlock code". But here I have a bigger issue. Based on AT&T instruction for unlocking HTC devices, you should have AT&T sim ( which basically I don't have one). I even tried putting other Canadian-based sims on the phone, but no "unlock code prompt" popped up. Is there any other way to get the phone ask for unlock code?
Thanks,
me tooo.

Sorry if that's a confusing question. So like... If I unlock right now on Bionix-V will it lock me down if I flash another rom (ANY rom)?
Because I plan on unlocking my phone early, and then switch to AT&T or travel to another country in the far-future. Just so I'm prepared and don't have to do last minute unlocks.
Dont know the answer to your question, but in the past I have unlocked every phone I have had through tmobile. I get the unlock code, have an old ATT sim card on hand just for this. I simply enter the unlock code when I slip in the att sim.
If you have the unlock code (usually sent via email from tmobile) saved somewhere, you can always re-unlock it if it gets relocked with a rom flash
When I bought my mobile, it was already unlocked. I've been flashing different ROMs since my purchase and so far it hasn't locked back down on me. However, I have seen my hubby's phone relock itself after a crash once and it's still completely stock - bloatware and all (very weird).
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.
yeah, it uses the device unlock app.no it says i'm not eligible for unlock.the seller who sold it to me even requested tmo and was denied.tried rooting and messing with system files now it says can't connect to remote server even after reflashing stock using LGUP.Tried using the f600l rom port, no you can't get the sim unlock prompt to pop up.tried blisspop and resurrection roms, they do prompt for a sim code but the codes do not work it says 255 retries remaining<<<something not right there.I do have the right unlock codes, just get them from an unlocking site or ebay.Speaking of unlocking sites, they want 60usd+ to unlock the tmo variant WTF!! Also if you try to get into the sim unlock menu using stock rom (dial 2945#*901#) it just says device permanently locked for everything.Now if there was a way to get a stock rom or port from say at&t variant which has the sim unlock prompt it just might work.
The closest i've got to unlocking this thing i the actual network unlock screen that comes after you flash the stock firmwire through LGUP. it said 0/30 attempts or something for a brief second or two the first boot after reflashing and then it restarts before you can even do anything into os never to be seen again unless you reflash it again but again you will only see it for a second and its gone again.I wonder if there is a way to keep that screen on so you can attempt to unlock it via code.
Also I'm pretty sure the device unlock app is just there to check prerequisites of your t mo account.In reality it does unlock the same way as other phones.probably just applies unlock code from tmo database once it checks you've met the criteria for unlock.
t-mo has really locked these down .
So has anyone been able to successfully unlock this phone without the tmo app? or have a cheaper service to unlock this thing ? Else im stuck with a paperweight.
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 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.
