You can boot to TWRP and flash magisk it will root on T-Mobile.

In TWRP make sure to back up your boot, and modem.

When you flash the global you'll lose signal , you can get it back by restoring the modem in TWRP.

Great, so TWRP on TMO 8 5g is working without issue? And which version of the Global for this phone is available? I just went to 10.5.8.IN55CB a couple days ago. What will be the latest full Global release and how were you able to install it? TWRP, Magisk or OTA? Is fingerprint working after all that? Sorry, trying to catch up, finally back to work and been busy. Always good to get someone else's experience for this. Thanks

Try this, this is what I did and so far things work.

I'm so confused. I'm a t-mobile customer thinking about buying a oneplus 8 5g 8 gb 256 internal unlocked on ebay brand new. I just read this entire thread, I assume the sim unlocking steps are because y'all bought your phones from t-mobile - is that right? If I buy third party unlocked, then I can skip the sim unlock and go straight to bootloader unlocking - is that right?

You are kind of right, missing 1 important thing - the MODEM

I'm so confused. I'm a t-mobile customer thinking about buying a oneplus 8 5g 8 gb 256 internal unlocked on ebay brand new. I just read this entire thread, I assume the sim unlocking steps are because y'all bought your phones from t-mobile - is that right?

Well, yes, you skip the unlock, but you need the T-Mobile modem that people here keep saying to backup before switching to Global. Why no one has posted it somewhere for download I have no idea, I will post it somewhere when my Op8 arrives since no one has, unless someone would kindly upload it here to Mega.nz or Androidfilehost... Also be careful with the international versions some don't support T-Mobile 5G bands (or that's what they say anyhow, they all have X55 modems).

Anyhow I'm just warning you here on my soon to be 3rd 865 phone and T-Mobile I couldn't pick up 5G on any of them, so I am "downgrading" to an Op 8 8/128 T-Mobile branded phone. I already made a super kernel (MOD Kernel in the forums here) for the 12/256 Red Magic 5G I'm typing to you on which supposedly supports band N41 prevalent in my town, but no one has actually been able to connect to it on T-Mobile. So I regrettably bought a T-Mobile phone even though I am using the fastest 865 phone already, for 5G...

Within 1 brand and phone model, yes, you can flash the modem. You can't between phone variants because of hardware differences. So if you do purchase an Op8 (not Pro) International and get an Op8 T-Mobile NON-HLOS.bin modem flashed via fastboot or TWRP I imagine you will pick up 5G from T-Mobile. Some phones like Samsung have NON-HLOS.bin and MODEM.bin; I don't know about OnePlus. TWRP should backup whatever # of files are in the modem partition.

If you still don't get 5G, well you can't do anything about it. I was looking at the 256gb models as well but decided to go the safe route. Tired of using phones that just don't get 5G on T-Mobile. Good luck! And if you happen to get 600mhz 5G please post here to let us know - as that's a T-Mobile proprietary band.

Hope that answers your question, probably more than you cared to know, but better to be complete than not enough information.

Someone was offering free unlocking and i bought the phone hoping to use this but the day after I spent the money on the phone he stopped doing it which was just great. Any other way I can unlock it?

I contacted t-mobile requesting an unlock for work travel. They would only do a temporary unlock...I asked if they can override and do a permanent unlock so I don't ever get cut off, they said they would need to have me speak to a technician on the phone.

Wtf.
 
I randomly clicked app it worked I'm unlocked had phone 2 months I was turned down it I'm on jump in my last post I put pics

TMo has a 40 days on network requirement for unlock, so 2 months would exceed this requirement.

I am in week 3 of 6 before I can unlock. I try every few days and it seems that the phone (and maybe TMo servers) record this, because it shows up in the history of unlock activities.

After the unlock, I read one needs to contact oneplus for bootloader unlock code which takes another 7 days. Ugh. 7 weeks to unlock everything. I hate being unrooted!

Cheers,
B.D.

    Not exactly unlock news, but, there is an update available for the T-Mobile version of the OnePlus 8.
    Only features named specifically is the addition of 5G on bands 2,66 & the addition of Google Live Caption.

    Just figured I'd mention it here vs starting another thread, since most T-Mobile users are following this thread anyway....

    Wait so how did you guys get sim unlock if the phone isn't paid off yet? Did you contact through the app or on the phone? I want to convert to international dangit

    As suggested by @matteosaeed I went to T-Mobile's Twitter help account. There I talked to an agent and told him that I was developing a couple apps and needed my SIM unlocked for testing.

    They unlocked it for me, no questions asked. I got it on the first try although there are times you might have to try a couple more than once.

    This is a link to T-Mobile Help on Twitter: https://mobile.twitter.com/tmobilehelp?lang=en

    Good luck!

    I just got mine as well. I have to work shortly so I'll have to wait until tomorrow to unlock.

    Might need some help with that as I've never unlocked a boot loader before. I'll do my homework though.
    It's easy to do. I'm sure if you search the threads on the OnePlus 7 Pro forums, you'll fly right through it. Just a few commands via adb. If you need help, lemme know.

    So now we just play the waiting game?

    Yep. Sadly. Contacted Oneplus multiple times and their support don't know what I mean by bootloader then they refer me to the existing page, telling me to contact T-mobile etc.. I keep checking if the page has been updated to include the 8 evert few hours.

    Also, the page that has the OP firmwares hasn't been updated to include the 8 series. Don't know what they're up to.
