SIM unlock and Boot Loader unlock questions - OnePlus 6T Questions & Answers

Hello there, I'm in the process of learning about the 6T for a purchase probably in March of next year. I'm watching prices on Swappa for both the unlocked and the T-Mobile variant. I'm currently using the OP5, so I'm no stranger to OP and I'm currently using T-Mobile as my service provider. I'm trying to figure out if the T-Mobile version needs to be SIM unlocked in order to boot loader unlock it? Or can I BL unlock while it is SIM locked? Basically, I don't care if I have the T-Mobile version because I only need/use a single SIM so it doesn't have to be the dual SIM. However I do want to be able to BL unlock it so I can flash TWRP and custom ROMs. I did some searching around and found info about T-Mobile SIM unlocking and BL unlocking, but nothing specifically answering my question. Thanks in advance.

I believe the short answer is no. Either you have to sim unlock it to unlock the bootloader or they have to sim unlock it so you can get the unlock token from OnePlus.

Official answer is no, you cannot unlock the bootloader with a locked SIM.
The XDA answer is yes of course we can unlock your bootloader with a locked SIM. Its been a work around since the device came out on T-Mobile or shortly thereafter.
All of this info and more info can be found in the guide I wrote here: [T-Mobile / Guide] - Full SIM and Bootloader Unlock + Root for locked devices

God Dammit are you are @Scott from the almighty N6???

I don't think unlocking the SIM card and unlocking the boot loader is the same thing. Are referring to the boot loader?

How and/or where to Unlock my phone?

I think you ought to have unlocked before going the U-way. Most unlocker I found utilize the Tmobile unlock app to unlock which is only found on the stock Tmobile firmware. I dunno. Anything is possible. I'm also seeking to unlock mine... I'm outside the US. So I guess I have better chance. Wish there was some free way though.. Goes from $20 to $30 on eBay.. Ain't no cheap unlock these days.

Not really but my guess would be you have to use the stupid unlock app that comes on t-mobile phones. Try www.cellunlocker.net , pretty sure they have the method to unlock using the t-mobile app.

Ok I unlocked 3 T-Mobile s7 edge devices thru unlock base and this is what you have to do
You have to flash the T-Mobile firmware back to your phone thru odin.. Take your sd card out and make sure to click nand erase all while flashing T-Mobile firmware .. You can do this before or after you purchase T-Mobile app unlock.. I did it afterwards
Once you have t mobile firmware on phone use the unlock app to unlock.. Then I flashed the U firmware back but I did NOT do nand erase this time.
My phone is on cricket unlocked and working
Remember to nand erase first or you will get a error on the unlock app because flashing other software such as U screws up the unlock app.. So do a nand erase
You do have to use the unlock app but doing it my way here works perfectly!
Works perfectly.. I done 3 T-Mobile s7 's so far

Unlock base claim they won't refund if imei was blacklisted. Does this mean blacklisted devices are not supported? Even if device was located abroad and used overseas outside the USA? Unlock won't work?

on the top of the unlock to be able to use the phone in the USA (and we're not offering cleaning service)
which means you won't be able to use in usa
but please contact them about it
I just got unclocked from a seller on ebay. Presently $69.5.. Before unlock my imei was blacklisted. But now imei appears to be clean. Is that how they unlock? Clean imei and then place a call to tmobile for unlock? If there's anyone wanting to unlock, go for esn cleaning 1st (about $20) and call tmobile to unlock your phone and see if they'll do it for free.

Sprint LG V20 - Unlocking

I have sprint LG V20. I purchased unlock code from a 3rd party, however when i insert a t-mobile sim it doesn't ask me for code or anything. Was anyone successfully able to unlock Sprint using a code?
Ditto
I am having that exact problem. I believe the issue is that sprint uses CDMA network settings and the other carriers use LTE/GSM.
Im trying to figure this out too. Im trying to use att card and get no prompt for a code. Just invalid sim card. Dialer codes dont work either.
Sprint v20(ls997) has no "unlock code prompt".It is both CDMA and GSM capable device but is "locked" to sprint. You have 4 options to unlock it
1: call sprint and ask for a unlock if the phone is paid off and not blacklisted (might work)
2: unlock via remote unlock from one of those unlocking sites or ebay listings.(tell them your firmwire and whatnot beforehand)
3:If you are under firmwire ZV7 firmwire you can try this https://forum.xda-developers.com/v20/help/lg-v20-cdma-to-lte-gsm-switch-via-t3602409 it requires NO root
4:you have to be under ZVC firmwire and root your device then you will have us996 rom which will unlock you device as well.
I have a ls997 rooted running on gsm just fine, just know there is no unlock codes for the sprint variant , like all sprint devices.

zvc is arb01, and has no root.So right now, you can't root or rollback to previous version to root. you will either have to wait for root( if someone is even working on it) or find someone that unlock for you using one of those unlocking sites but they do charge quite a bit for a simple unlock.

Help Unlocking T mobile 6T

There is an app.
You use the app that's preinstalled on your phone.
yea that isn't working for me... I tried it and it just gives me an error code
Is the phone paid off in its entirety and did you wait 40days after you brought the phone?
If you just want a temp unlock, I think you can request it on the app.
So there is a forum here on how to convert it to the international version. That's what I did. And I completely bypassed needing to wait 40 days and paying off the phone. If I find the post I will link it for you

Yes, I paid it off once I got it and I waited 40 days. I think the app is just broken for me.

I have converted to international version but its doesn't unlocks sim I have ordered sim unlock service from https://www.cellunlocker.net/t-mobile-unlock-app/ after sim unlock you can convert to international version. If your phone has bad imei (financed) you cant use phone in USA. If imei is clean it will work with any network in USA

Sim unlock s10+ from sprint to metropcs

Good morning. I was just curious, is there anyway to unlock my phone myself using ODIN?
If so, is there a link to the correct files I would need?

anyone?
NO not compatible
What do you mean its not compatible?

You need to have Sprint unlock it first and they require 50 days with service on that device and no outstanding bill.
Then you can put in your MetroPCS sim and call Metro and they will add the IMEI and it will work fine, or if you want, download the unlocked file and flash with ODIN to remove the bloatware.

It will let you use any carrier as long as the SIM is unlocked.
If the sim is locked by Sprint you need them to unlock it first.

The carrier must unlock it first. Then this allows other carriers to work. But if Sprint has it locked you are SOL.
