OnePlus just informed me they will NOT unlock bootloader for a device on bought on Ebay.

@vverve Good suggestion. I just did it. Not reported lost or stolen. I had not done this previously because I purchased from Ebay seller whose main business is cell phones, over 30,000 transactions and almost 100% feedback. So, they seemed quite reputable. (and have been great at communication).

@oldbutndy Ok , then double odd .. have you ever contracted with tmo ? you are in US ,right ?
They were , at least on xda in 2022 that guy you wrote one+ did
provide bootldr unlock even on sim locked device ! + me = 2 .
Trying to pinpoint your refusal ,
as we can enjoy AI random bull*h!t deep diving :
government-customized version devices could be one reason ,
or , out of luck , you got a clean imei but devices ,reputable seller , but devices had suspicious activity history ....
ah ah , no , AI does not link government-customized to suspicious activity ....i do...joking about it, of course .edit....Note ; Dont get me wrong , i have not been able to install UT on that latest bootloader unlocked device , so , must agree with all , if UT is your goal , avoid such sim-locked devices , but they do goes for cheap .

@vverve Yes, I am trying to pinpoint specific issue also, so as not to waste time in future: Mine, sellers, and others who read these posts.
I never activated on T-Mobile directly, but bought a T-Mobile SIM via MVNO (USMobile), & configured on the Pixel 3A (Android 12 stock) first (I think).
I asked Oneplus if they could provide more detail, but they did not.
I read about the government customized issue, and also 'black listed' issues. The IMEI checking webpage offered black list checking, but for a $ fee, so I did not do that.
I also read that Oneplus might refuse bootloader token if someone else had previously requested unlock token. Maybe my phone had that problem.
The easy unlock model BE2026 seems extremely rare on Ebay, and Facebook marketplace is challenging to search (random results - high quantity to review - mostly not even Oneplus, or Nord, or N10, depending on what search terms you try).
I really hope UT developers get OP 8 series working, just to increase number of possible devices to try (but a recent AI answered suggested 'late 2026, maybe').
I even considered a Braxphone 3 listed on ebay ($400 !), since I read they recently got UT basically functional. -
@oldbutndy And if you have previously requested a token in the recent past for another device - according to people on xda-developers. Not saying you have, just putting it out there for those following along at home...

edit....Note ;
Dont get me wrong , i have not been able to install UT on that latest bootloader unlocked device , so , must agree with all , if UT is your goal , avoid such sim-locked devices ,but they do goes for cheap .Hmmm , guess what ? not a straith foward installer success first shot , but lito device ,msm tmo2global,debloat,oem unlock,unlock bootldr , it did install UT .
Got stuck in recovery 3 times in a row ,please dont ask why ,but it did installed !! a hit–and–miss kind of project ...as @oldbutndy testymony + mine. -
@oldbutndy download the EU firmware (EOL) and the real firmware for your version for EOL, then copy the identifers in the scatter xml file from that version to the EU one, then flash through EOL phone will check see T-mobile or whatever it is you have pass the check and flash EU rom with unlockable bootloader worked on my N100

Thank You. I read a bit about this option, not not enough for confidence yet. I am still within return window for ebay, and prefer not to mess up the phone in a way I can't restore to what seller sent me. I am new enough that I expect that is possible, but not sure I, personally, won't screw it up. I will read more.

@oldbutndy The porter is also looking into this. Will update if we figure out why it did not work like the N100.

UPDATE:
I ordered another (low price) Oneplus Nord N10 via Ebay (stupid me).
Seller stated 'BE2029', and FACTORY UNLOCKED.
Seller did state phone would NOT read SIM, but I was OK with that. (see below).
I thought that I could at least install UT, and use it for everything but cellular (I read that band 17 NOT on BE2029, and T-Mobile (my spare SIM) requires that).
At least I could get started with UT !
When it arrived today, it flashes T-mobile on boot screen (uh-ohhh...), then in Settings, shows BE2028 !
Very depressing.Anyway, this inspired me to ask for more details on the process you mentioned, of downloading 2 different install files and merging old valid info into the file we want, so it will install even with locked bootloader.

I did not yet try what ChromiumOS-Guy suggested - downloading 2 files & merge relevant bits from EOL official into newer.
Is your comment saying someone else tried on N10 and it failed (whereas it worked for N100 ?)
If you know this process, please explain or send relevant link. I will try.
