Help unlocking t-mo 8t bootloader - OnePlus 8T Questions & Answers

Can't get t-mo to give me the sim unlock to get my bootloader done. Any help by chance?

From what I understand is this; the people who are unlocking our SIM's are risking there job so they all sorta retired. Maybe one of them will see this and help you out. IN the meantime...
Have you tried Googling? I found this as the first site: How To Unlock T-Mobile OnePlus 8T | UnlockLocks.COM
They have a sim unlock service. There are others but I just wanted to illustrate that there are companies that can do what T-Mobile refuses to do.

I checked but not willing to pay 89.95 just so I can unlock my bootloader.

AT&T Tilt Unlock Question

Hello, I am new here. I have been reading for days and days now, and I have come up with a question:
I have a brand new AT&T branded Tilt that I want to unlock. I found the Sim unlocker on the stickie. The question is this, AT&T has already provided me with the unlock code for my IMEI number, so if I just use their unlock code will it stay unlocked forever, even if I flash a new rom to the phone? Are there any benefits to using the XDA Sim unlocker versus the unlock code that AT&T provided to me?? Will I still be able to use the phone anywhere in the world with AT&T unlock code?
And what about those internet sites that claim to unlock your phone for a fee, do they work? Because a friend of mine wants to unlock as well, but is scared of the process found on XDA.
If the AT&T unlock code will work, how do I do it??
Thanks for any help.

The Unlock Code that AT&T gave you should work fine. Once you do a SIM unlock it be will be unlocked forever.
Thanks for the help! What about the internet sites that you pay for the unlock codes, do they work??
How do I use the AT&T unlock code?
Sorry, but I didn't find any info on the wiki about that.
You put in a non AT&T sim card and it will ask you for a code. You enter a valid code and you are unlocked.
All the Unlocker does is find your unlock code due to a hack on the radio.
I wouldn't be suprised if some of these sites that sell unlocking actually wouldn't just sell the instructions available free on this site.
Its very easy for your friend to unlock his device. Just follow the instructions. Now, don't hold be liable but I'd say there is a 99% change of the hack working. I did it fine. Took me maybe 30 mins to read and then follow instructions.
No Worry, i did the same thing and works..
Call AT&T explain that you need to use oversea SIM at different country while you travel as for business. they will ask your IEMI code and email unlock code within 3 business day, i just get mine and work perfectly without worrying screw up the radio cracking method and $$$ free.
Great this was very helpful. I am hoping to purcahse a Tilt from At&t on my US account then use my China Mobile sim while I am living here in China. The reason I want the Tilt is for the Chinese language software Pleco. How has everyones experience been with the stylus and screen on the Tilt. Are there any other At&t based devices that I should look into or wait for?

I used the free SIM unlocker here and it works great. I like the Tilt, stylus works fine, my finger - not so much lol. I'm looking into getting the Fuze.

[Q] Sim unlocked, anyone?

So, I have an Xperia Z3, D6616, stock, locked bootloader still, and I'm considering sim unlocking the device for use on AT&T. Bought it on craigslist. It's currently locked to T-Mobile. Most unlock websites say not to purchase the unlock code for the device if it is locked to T-Mobile due to an unlocking app that T-Mobile installs on handsets that prevents third party unlocking. See attached pictures. I'm an AT&T customer, so this is a bit of a pain for me.
Called T-Mobile, they will not unlock the device as it does not meet the requirements. I'm not a T-Mobile customer either, so there is no account history associated with this IMEI. I have a feeling that someone bought this device at a subsidized price, sold it new in box, and pocketed the cash. Now I have a fancy T-Mobile MP3 player and digital camera that won't play nice with my AT&T sim....
Has anyone successfully unlocked this device for use on another GSM carrier while originally being locked to T-Mobile without going through the carrier's unlocking process? If so, what website/service did you use? I'm considering selling this thing as it's a bit useless on my network thus far, being locked to another carrier and all.
Thanks in advance.
is this me being a bit daft, but could you not simply put an unbranded firmware on the device via ftf and simply unlock the device via a website?

I'm not sure if that's a possibility. There is no root for this device without unlocking the bootloader, which wipes the TA partition and causes you to lose the DRM keys and cripples camera functionality. I'm trying to avoid unlocking the bootloader for as long as possible, but if unlocking, rooting, and installing a custom ROM will assist in sim unlocking, it may be in my best interest to do so.
I'm trying to do a network unlock with a code and keeping the phone stock if at all possible, at least until a root method without unlocking the bootloader is found, if it ever is... I just need a way to get a code for unlocking WITHOUT going through T-Mobile.
you don't need root to flash an unbranded ftf., once done then simply use a website and buy the unlock code, with the tmobile firmware out of the way there shouldn't be any interference in terms of network unlock.
what i am saying is:
1: flash global unbranded firmware via flashtools with ftf
2: buy your network unlock code
3: enter code as no t-mobile firmware is available on the device anymore to interfere
i am not saying this is possible as i do not have a t-mobile - us device to test, but my vodafone branded z3 has had an unbranded firmware flashed by myself with no root.
i hope this helps clear up any confusion.

I may try this tonight.
If I flash another firmware with flashtool, can I return to stock after unlocking without root access?
Rooting and/or unlocking the bootloader or flashing a custom rom or a different firmware has absolutely nothing to do with SIM lock.
If you try and sim unlock by doing any of that you are wasting your time.
Best bet is to go to your carrier and ask them to sim unlock it

Yeah, that has been my experiences in the past. The carrier always did it for me. But T-Mobile will not unlock this device as it does not meet eligibility requirements, and the unlock websites say not to buy a code for a T-Mobile US locked Z3. I need it unlocked for use on AT&T. I remember unlocking HTC devices with SuperCID and unlocking Samsung devices with dialer codes. Anything like that for the Sony side of the house? this will be my first Sony phone.

Not that I know of. In the UK you can get any phone sim unlocked on any market stall in a few minutes for a fiver. Its not really to do with the phone but the carrier and the laws you have over the pond.
Simply try a websites unlock, I do not believe T-Mobile can block carrier unlocks. Who has told you otherwise?
See the attachments in the OP. The unlocking websites are saying not to purchase the codes if you have a T-Mobile US locked Z3. I don't want to waste $40, especially when there are no refunds, and want to know if anyone has successfully unlocked with a website and NOT the carrier.
D6616 has an NOT unlockable bootloader, so that method is a no-go.
If it was on EIP and they sold it, the phone may be blacklisted by T-Mobile already
I don't believe you can flash a different version firmware, for multiple reasons, one of which is because it's a D6616 and not a D6603
The T-Mobile SIM unlock tool does work if all conditions are met.
Good luck OP, I think you might have a difficult time with this one

Again, the bootloader status has nothing to do with SIM lock.
Flashing another firmware will also not effect sim lock.
I'm seriously considering selling this device and going for another bootloader unlockable handset due to this unlock headache. T-Mobile is no help for unlocking this IMEI.

Sorry for the first line, didn't mean to get that wrong. Definitely agree that bootloader unlock and SIM unlock have nothing to do with each other.
Called T-Mobile again, tried to unlock. No account number to tie unlock request to since I use At&t as a carrier. They recommend I call Sony directly and ask for an unlock. I did, Sony told me to contact the carrier again. I do, and have the T-Mobile rep call Sony guys on a three way call. I explain that I purchased the device on craigslist, not a T-Mobile account holder, I'm an active duty military member, phone was several hundred dollars, I didn't know... boohoo, I'm dumb, I should have purchased from Sony, No moneys to get a new phone since this was so expensive, etc. Sad poor me story, you know.
Sat on hold for a bit, but Sony caved and said they would attempt a remote unlock via code, but it would be between 1-3 days and the reply will be via email. Time will tell, now. Just waiting to see what happens. I hope it works. I had to have the situation escalated to the third level of supervisors to get this far...
sounds like good news, if that fails, you could ask someone you no on T-MOBILE or a family member to give them a ring and pretend its there phone, should also do the trick
That's a good idea!! Thanks for that. I'll find someone at work who has T-Mobile and go that route if I need to.
any updates.. i badly need my T mobile Xperia Z3 to be get it unlocked...
Sadly, there is no update. T-Mobile will not unlock the device unless I use it on their network for 45 days, ahve an account in good standing, etc. This isn't going to happen, as I am an AT&T subscriber. I have the Z3 listed for sale on craigslist. Awaiting a sale or trade. If anyone wants to swap phones for a still in the box T-Mobile Z3, let me know. Looking for an S5, G3, or Nexus 6. Gsm variants only. Too bad, cause I really like the Z3. I would keep it if I could sim unlock.
Is the unlocking app based off the Sim card? Cause I bought my tmo Z3 3 days ago. Used my Sim from my moto x. After I got everything set up I tried the permanent unlock which was successful.

Network Unlock TMobile OP8

Is there anyone who can do this ? I saw someone offering the unlock for free...believe his name on here was mobbdeep?? Service is TMobile, phone came directly from TMobile as well, and have had acount for a few months now.

Sorry bro, he closed that thread a while back. It was legit, he unlocked both of mine. Keep a look out to see if he will do it again. Otherwise you may have to call TMO and persuade them to help or tweet the help desk. Happy modding!
So maybe I can give some help with information. T-Mobile will not allow you to seamlessly network unlock without a full payoff. You can typically contact T-Mobile's Twitter and get them to unlock it if you have a specific reason. According to someone I know directly in their support, they will typically unlock with minimal hassle if you have at least three device payments. However, you can typically get an unlock earlier if you give them a valid reason. A lot of people reported network issues with an OTA. Referencing this, and informing them that a bootloader unlock is necessary for repair, they unlocked mine with literally a single payment on file. It took a bit of persistence (and even referencing the XDA thread), but they did unlock it for me. Give it a shot. Worst they can say is no.

i'll have to give it a try. this is my first tmobile OP variant and i'm already upset that i didnt buy unlocked directly, i just didnt have the full amount up front and really needed a new phone. went with the 8.
Look in the 8+ forums. I just got my 8+ unlocked a few days back. I messaged the person and she got back within about two days. After that I sent her my info and I was unlocked in a couple hours.

Which thread is it in I'm having trouble finding it.
I just called T-Mobile and they approved the unlock for my OP8 (purchased in August 2020). My reasoning was T-Mobile is paying half of the phone (50% off deal) and told them I will be paying my half early (around $230 left). So they said yes to unlock my phone. Give it a try.
What if you buy a T-Mobile locked 8 on ebay? I thought you could still unlock bootloader with msm, am I screwed?

You need to request an unlock token (bin file) from Oneplus to flash before you unlock the bootloader.

Yeah but I bought the phone off of eBay so I don't think they will unlock. I am thinking of paying for an unlock service that costs around $80-$100 (I don't know of any legitimate ones) or returning the phone and buying the n10 5g. The only thing preventing me from getting the n10 5g is the lcd screen, that is a major issue for me.

though you bought it, are you a tmobile customer? I think if the phone is already paid off, and you use the phone on their network for at least 40 days straight, then you should qualify for an unlock.

I got my TMo OP8 off Swappa and just requested the unlock code from the OnePlus website the day it arrived. It took 7 days literally to the minute to get my unlock code, which I hear is the norm.
But also note that we're all talking about 2 different things: a bootloader unlock (which is what I did) and a carrier unlock (which is what OP was after, I believe).

when i checked the oneplus website for bootloader unlock it required an unlock code from tmobile. can you link me to the page where i can request the bootloader unlock?
edit: I am an idiot, disregard that.
Can you help me with getting the unlock token? what exact commands did you use to get unlock code? I followed the oneplus guide but get the response-
"C:\platform-tools>fastboot.exe oem get_unlock_code
FAILED (remote: 'Please enable OEM unlocking in Settings first')
fastboot: error: Command failed"
my understanding is that you need to sim unlock before you can oem unlock.

this is what i had the ebay seller i got my phone from do, and apparently they are going to unlock tonight; the rep said the phone needs to be used for at least 48hrs on tmo network, but preferably 40 days before unlocking. It seems they have an official policy on carrier unlocking and then another policy which is only used on twitter; all very confusing. my concern now is that custom roms will not work correctly on tmo op8t, as verizon owner have reported crdroid not working for them.
Ok mobdeep is back in the game of unlocking TMO phones. Head to his thread and read the info. Happy modding!
So I have an unlocked carrier t-mobile device and I want an unlocked bootloader. Who do I need to contact to get the 7 days rolling? Thanks

Then head over to unlock token - OnePlus (United States) and apply to get your token, which took me 1 week exactly.

Question Rooting/Bootloader Unlock for T-Mo variant

Hey all,
My family's looking at switching to T-Mo as my son's in the military and that have a great plan for that. I've always had unlocked OP phones, so the T-Mo variant is new to me. I've seen there's different things you had to do to unlock it.
Is it rootable without the SIM unlock? And the only way to unlock the bootloader is to have the SIM unlocked, correct?
And wasn't there a way to get it unlocked if you're a developer - even if it's not paid off?
Just looking at my options you see if T-Mo would be doable for me.
Thanks!

Hello! I have unlocked the bootloader, how to root T-MOBILE ONEPLUS 9! I don’t have boot.img
Bumping
I saw that there's an MSM tool to convert the TMo version to the Global version.
Of course this is after the SIM unlock.
I've done some reading but I'm not sure I'm understanding.
I seem to remember there was something weird about the modems on TMo's version. Does the conversion take care of that so it's all "normal" after that?
And I take it I can unblock the bootloader normally after that too, correct?
I've worked on my son's unlocked 9 and that's all fine. But I'll a little confused on TMo's. Never worked with out and we're in the process of switching over.
Just wondering so I can determine off I'll get TMo's or wait a bit to get the unlocked version.
Thanks,
Super

Absolutely, I could not get them to unlock my 9 despite them doing so on my 7 pro and 8. Something definitely changed and the dude doing helping out on here saved me.

Question I have a F721U, T-mobile, is there a way to unlock it from the network?

Hello, I am investigating how to unlock the Samsung, someone who can guide me?
As far as a SIM unlock? Pay off the phone and it will unlock automatically. If you can't do that, you're going to have to pay for an unlock on ebay.
Only possible by online service
