8T TMobile Unlock Oddities - OnePlus 8T Questions & Answers

Hi guys! Having some weird issues getting custom roms to flash on my 8T. I purchased the TMobile variant as it was the only one in stock, and I planned to use it with a TMobile mnvo. It's the KB2007 model. I purchased it outright, and went to unlock the bootloader - this was not possible as the device was locked. I reached out to TMobile on Twitter, gave them my phone number, IMEI and told them my story. They said it would take 2-5 business days for the unlock team to look at the request as I wasnt a direct TMobile customer. A few days later, I went into the android settings app, and attempted to permanently unlock the device and it unlocked. I rebooted and was able to toggle the developer setting to allow OEM unlocking, yay! Since that point, I've ran the kebabt -> kebab EU firmware MSM tool to convert the device to the EU firmware (as I've heard it's more stable, I'm US based though)
However, after that I've gone to replace oxygen os with Lineage, and I'm getting errors from fastboot about the device still being locked. Any ideas where to go from here?

You probably need to unlock your bootloader?

You will get fastboot errors about unlocking critical partitions if you try to flash partitions other than boot, recovery and a few others while you're in bootloader mode.
For the rest you must be in fastbootd mode.

Chances are you need the unlock token from OnePlus themselves it takes a week

Would installing unlocked bootloader and firmware unlock the phone?

So what I want to do is switch this phone to straight talk but want the att bloatware off this. If I install unlocked firmware and root the device would that make it unlocked? Like not carrier locked. Straight talk said I can already use a Sim despite it being locked but I wanna unlock it myself.
I don't think att will yet and not sure if they will at all. I'm converting my chapter 13 bankruptcy to a 7 on Tuesday and att bill is rolled into it so the phones will be mine once that is discharged but not sure if they will unlock them right after or if it will take months,that's why I'm asking this. I already reinstalled att firmware on this phone because I tried to install a custom room and messed up due to the bootloader issue of it being v5 I think.

Att Note 8 Sim relocked?

Hi guys i hope you can help me.
I'm from Mexico. Some months ago i received as a gift an AT&T Unlocked N950U device. Yesterday i updated my device to Android 9 N950U1 XAA unlocked version with no problems except for the device asking for an unlock code. I tried to get an unlock code from the official site but it says the device is reported as lost or stolen???? (I believe it was a device some people sold and then they went to at&t and said the device was stolen to get a new one).
Now. I was thinking 3 options:
1.- Try to get the code with some credits from an unlock box.
2.- Buy the premium code from some ebay reseller.
3.- Try to go back to oreo but bootloader was uploaded to bit 6 so...
PS: I don't know how it was possible for an unlocked device to lock again after flashing a diferent software version. I firstly tried to update the official way but since i'm on mexico and an at&t sim card is not installed on the device an update is never found. Also i didn't find any Pie update for at&t to flash with odin.
Ps2: The glass is broken and the screen only works if you set brightness above 70-75% so if i flash anything the update wizard is a pain in the ass(because screen is totally black) i could pass thanks to Talkback.
What you think? What is the best i can do now? Screen replacement is not an option at this moment...

Unlocking bootloader on ebay purchased TMobile 7 Pro

Thinking of buying one of these and want to clarify the process of unlocking the bootloader. From the ebay seller he says it is a T-Mobile phone but is sim unlocked already. He says I will have to contact oneplus to get the bootloader unlock code/token. I don't really want to wait the forty days or whatever I heard it was but it's ok as long as I can definitely get it unlocked eventually and won't be stuck for some reason with a locked bootloader. Thanks for any info you can provide.

I've ran across two of your posts asking the same question. I had done the same thing as you. I bought an eBay sim unlocked op7p. At first I flashed the international firmware to just bypass the whole tmobile bootloader unlock. It worked in the sense that I was able to unlock the bootloader, however I had no service and the phone would not detect my sim (Cricket). I tried another sim with the same results. I had to use the msm tool and flash back to tmobile stock firmware in order for it to work with my sim.
I sent in my request for an unlock token and received it in 7 days. I think the 40 days is only for brand new phones. I would submit the unlock token request and go that route. YMMV, you may very well be able to flash the international software and just bypass it. I didn't have that luck. The 7 day wait wasn't so bad. Hope this helps.

That's good to know that I can get the unlock token if needed. So TMobile doesn't care who you are or that you don't have a T-Mobile account or live in US obviously then?

The unlock code comes from OnePlus. I only had to wait the week and the received an email with a link to download the unlock_code.bin file. To answer your question, not to my knowledge.

I think I may be in the same boat. After fighting with msm I finally got it to flash the international firmware but nowjiy doesn't detect my sim. So you went back to Tmobile software and got the token to unlock but once you did that did you switch back to international or custom ROMs?

I have not flashed back to international because I couldn't get the phone to detect my sim even after updating the international firmware.
I would however recommend that once you flash back to TMobile (using msm) that you do the OTA (settings>system>check for updates)
Currently I'm running unlocked and rooted via magisk. I'd like to flash a custom rom (looking at resurrection) but they say to flash the international rom to both slots first (via recovery like twrp) and I'm not sure if that would cause the sim issue again. I haven't had time to ask about it (if I can flash straight from tmo stock rooted to a custom rom like resurrection). So unfortunately I don't have the best answer there. You may ask around in some of the custom rom threads about just flashing straight from the TMobile stock firmware with unlocked bootloader. If you happen to find out an answer, please pm me and let me know.

Actually I was mistaken. Once I updated the international rom to Android Q my sim started working again and now I am on Bliss and sim is still working. Not sure what is going on with your sim.

Flashing LineageOS for MicroG on 8T (T-Mobile Variant) purchased from OnePlus

Hello all!
Thanks for taking the time to click into this.
About me: I mostly see myself as a somewhat tech-savvy noob - I have rooted several devices in the past, flashed ROMs, etc.
New Device: OnePlus 8T T-Mobile Variant purchased from OnePlus.com
Condition: Brand New - never started the device
I would like to essentially imitate Calyx as described here.
=> install TWRP/Magisk + flash 'LineageOS for MicroG'
Questions:
1) Will I be able to unlock the bootloader given that this is the T-Mobile variant purchased from OnePlus?
2) Do I need to take additional steps because this phone is the T-Mobile variant?
3) basic question: I have never started the phone so it has no personal data - should I back up the current setup in case I need to return to OOS for any reason or can I track down the default OOS installation making that all unnecessary?
(I remember in the past default Samsung installations were easily tracked down and flashed using Odin).
4) Would you recommend any detailed instructions to go through the process of backup, installing custom recovery, accessing root privileges, flashing LineageOS for MicroG, etc?
(I feel like I am piecing parts together from different places and it's all not fitting together)
Thank you so much for reading this.... I feel like I'm going down several rabbit holes currently so any perspective or support is welcome!
It would be helpful to hear any thoughts from some more experienced peeps before I move ahead.
Thank you!
Currently, I am trying to get the SIM unlocked, then unlock the bootloader, and proceed with the plan above.
I am considering returning the phone and getting a different one that has more users on XDA to avoid having bizarre issues arise with the steps involved with the T-Mobile version of the 8T and being totally on my own.

whoa! that's helpful feedback. Thank you for posting!
Based on your comment, I am leaning towards returning the phone.
I think I learn best through examples and may need a little support.
I am now wondering how I can figure out which phones have the largest 'community' on XDA.
I have the T-Mobile variant. There's more support and options available so don't be discouraged.
Normally, you have to be SIM unlocked before you can do anything else, like bootloader unlocking. If the phone is being paid for or financed and you haven't been a long time customer you may or may not get it SIM unlocked.
That said, I got mine SIM unlocked after contacting the T-Mobile Tforce people on Facebook. Then I saw this thread on Rebranding the T-Mobile variant.
[GUIDE] Convert TMO to EU via MSM Tool, no SIM Unlock or Bootloader Unlock needed!
*** Use this at your very own risk. *** You will lose all data *** Backup your working modem and persist, just in case *** Read the entire post and follow the steps closely before asking for help. Post all error messages and steps you took...
forum.xda-developers.com
Following it I changed the T-Mobile firmware to the European firmware. If nothing else you get more recent updates and a local update feature (full OTA updates can be downloaded and installed locally). As a result of the conversion I was able to simply fastboot unlock the bootloader without need for waiting for a code from OnePlus. The phone is now bootloader unlocked and rooted with Magisk.
Note that according to the OP, SIM unlock is not necessary for the conversion but you'll still need to be SIM unlocked to be able to unlock the bootloader.
Now that I'm "free" I now have the itch for a custom ROM. Over the years all of my devices run either with microG or just UnifiedNlp but no Google. I feel the need to do the same here. Currently I just have most Google apps disabled and using FOSS apps in their place but still...
Besides LineageOS for microG, the 8T also has Carbon ROM and crDroid. They historically have always had signature spoofing support so I assume they still do with Android 11. That means microG can be used.
Check the guides and ROM/Kernel threads for more info.
I don't know if I can get to trying anything this week but I hope to. I work at a drive-in movie theater and with Spider-Man coming out this week I'll be quite busy.

Excuse the late reply.
No, not too versed on this device really. I searched for that error and got a lot of hits but didn't have the time to read up. Sorry.

Not able to unlock bootloader on Motorola website

Is the Motorola website not working properly for unlocking the bootloader on devices? Every time i try to request the unlock key for it a page that only says "There has been an error with your request." appears. What can i do to unlock the bootloader even with this error?
Where did you get your phone? Some bootloaders are not unlockable.

If the previous owner possibly still owes money on it then you can't unlock the bootloader. You'd have to get the unlock app from TMO and they'd have to authorize it to make it unlockable bootloader, which TMO won't do if there's money owed on it.
You should be able to unlock it. The exception is if the previous owner relocked the bootloader. In that case, the bootloader cannot be reunlocked.

the Device Unlock app says that its permantly unlocked
Edit: the seller i bought it from said the IMEI associated with the phone was clean and said it had no problems having to do with not being paid off
I am also having a problem. This seems to be a problem with their website. I tried different browers, computers, and connections. Get that error every time after submitting the device key.
I tried with my new G100, and I have the same error. Any idea of a workaround?
I am having the same error with my Motorola G Stylus 2020 it has to be with their websites ive tried different browsers, computers, they need to solve this issue!!!
same error, i pray their system is down temporarily, G100 with different browsers.
I tried all methods that involve the motorola website I found on the forum but none work. I contacted motorola support, I'll keep you posted if I find anything.
Same here. I called and finally got level 2 support which said they couldn't help. They sent me to the motorola forums where I've asked about it. Will post if I get a reply as well.
Here is a link for the motorola unlock bootloader thread. Post your device ID there

I asked support and they told me the site was down and should be up in a few day. I re-tried now and it worked. I got my code. But the OEM unlock option in the developer settings is still grayed out. Apparently I have to wait which is stupid, I'm very close to just return the phone.

Yep. i did it just now and the site seems to be working again
confirmed working again
Ok, for reference, as there are some different things scattered alongside the forum.
I have a G100, german model (I'm in switzerland, but it's considered german).
What I had to do:
- go here <https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a>
- contrary to what customer service told me, the global portal works, even with a german model
- the website was down, but it's up now, if it's down for you, I guess you'll have to try again, customer support did not help me
- BUT, to be able to use the unlock code with `fastboot oem unlock <code>` you need first to activate "OEM unlock" in the Developer settings.
- To access this settings, you need to activate the phone. Some says it works on wifi, but I used LTE for the initial setup, just to be sure. After the setup, I did a few calls, I don't know if this is significant, but the first call took like 5 minutes to connect (I say this because you might be tempted to turn the phone off right after the activation). I applied all the updates, left my phone on my desk, and after 72h this settings was accessible (not grayed).
- After toggling the setting, you can use `fastboot oem unlock` and proceed with lineage installation
I just successfully bootloader unlocked a Moto G 5G (2022) using the website. It took them about five minutes to email me the unlock code after I submitted the string on the website.
Keep in mind that you are referencing two different things: network locks, and bootloader locks. The device may have a clean IMEI and be network unlocked (you can use any carriers SIM in the SIM tray). This doesn't necessarily mean that the bootloader can be unlocked for purposes of flashing custom ROMS. You'll need a phone that is both network unlocked and has an unlockable bootloader.
that's why wiko is better........
I'm having the same issue but with my xt2131-1 model. I received the unique code via email and it says failed to validate code.
