Oneplus 8t 5G Unlock help needed - OnePlus 8T Questions & Answers

Hello, hope this finds everyone well. I have been looking at the related topics and saw a post by @mobbdeep which had helpful information but I was unable to get ahold. If anyone knows a way or someome that can help I would highly appreciate that.
Thanks!

Update: Just spoke with T-Mobile and they said we don't have anything called "Unlock code" that it would be something you get from OnePlus. Does anyone have a clue?
Thanks.

Make sure you have adb and fastboot installed and OEM unlocking selected in Android, then boot into fastboot by using "adb reboot bootloader". Once in fastboot, use "fastboot oem get_unlock_code". Copy the code, remove all of the weird formatting so it is one consistent string, and paste that into the unlock code box at oneplus' site.
If you are wanting to unlock without paying off the phone, you will need to wait for mobbdeep to get back or try your luck with T-Mobile's Twitter. There was a well-documented bug in later firmwares on the original OP8 which caused people to lose signal, with the only way to fix to use MSM to roll back. I was able to request an unlock with this.

Thanks for your reply! I am familiar with everything you mentioned in regards to fastboot commands. However, the OEM unlocking option is grayed out meaning i cannot toggle it.
I will attempt the fastboot get unlock code command and hopefully see some magic.
Yea i'm in on waiting for mobbdeep. Hopefully he'd be able to give some insight. His topic post is the most relevant to my issue. I'm now going in on 3rd day with carrier sim in the phone.
What's MSM you mentioned? I read it in a few places here but what is that tool used for?
Thanks again! Have a great day.

You will not be able to issue the fastboot commands with the OEM unlocking option greyed out. The only way, currently, to get that option, is to have a permanent SIM unlock on the device. There are talks in the Verizon thread about a working workaround for bootloader unlock, but I am unsure if that particular method is working on T-Mobile devices. As for MSM, it is the unbricking tool for our devices. There is a special download mode that can be triggered in Qualcomm devices by holding volume up and volume down with the device off, and inserting a USB cable. Should something happen catastrophic to your software, and recovery through fastboot isn't possible, MSM allows your device to be returned to stock software. It will automatically relock your bootloader, and does not touch certain partitions like persist (individual fingerprint calibration files are in this partition), but it does completely recover your device in extreme cases. I actually misspoke in my post, as MSM is available on all devices. I meant the fastboot ROM restores, as that does require a bootloader unlock.

Unable to unlock bootloader (OEM unlocking disabled)

Hello,
I couldn't unlock the bootloader as the OEM unlocking's disabled and i can't access system! Everything's erased!
Any help????
A bit more info might be helpful mate.
What did you do to arrive at the situation you are in?
Can your pc see your device via ADB and if so what are you using: latest platform tools or toolkit?
Can you boot to stock recovery or bootloader?
Without any of the above info its going to be extremely difficult for anyone to give any kind of answer.

The device isn't recognized via ADB.
I can boot to Bootloader
The phone was working fine with the latest google stock android 10, i decided to lock the bootloader cuz the phone was getting overheated so i thought it'd be a good idea to lock the bootloader. Prior to do that, it asked me to erase everything! I erased everything and when i tried to reinstall the stock image it asked me to unlock the bootloader!!
The problem is that USB debugging isn't enabled and the phone is empty with no system!

Ouch! That's a right old situation you have there mate, with no OS installed a locked bootloader and no ADB function I'd have to say your phone is non recoverable!
Sorry mate but I can't see anyway out of that lot.
Maybe someone else a bit more knowledgeable might chip in but I'm deffo out of ideas.

Try switching slots, assuming the pixel is an A/B device. Maybe you still have a bootable system in your other slot and I don't think you need an unlocked bootloader to switch slots

Make sure you have the latest fastboot. On the bootloader your phone will either say "slot a" or "slot b" and you should type "fastboot --set-active=b" if you are on slot a or "fastboot --set-active=a" if you are on slot b
still didn't fix the problem... any probable solutions please?

simple , go to about phone and try to find build number,
after you find build number tap on it until it says you are in developer mode
after that head on to developer option (it may be inside about phone section or above about phone section) turn on the option which says allow oem unlock. then,
just reboot to recovery mode either by pressing volume up or volume down key with power button.
after you enter recovery connect usb cable and open command prompt in pc and make sure that lg device drivers are installed on your pc also make sure you have adb and fastboot installed.
ok, after all this type command
adb devices
if any thing shows us then you have successfully connected your device.
after it type
adb reboot bootloader
then your mobile should restart and show fastboot mode in screen
type command
fastboot oem unlock
and done your bootloader is unlocked.

I doubt that's going to work, but let me know if it does. Carriers and manufacturers use a variety of sophisticated security schemes like requiring lengthy codes that only they can provide, etc to purposely make it very difficult to unlock bootloaders. Tmobile gave me a K51 for free. They apparently feel the have to pay for it by spying on me. I bought a moto g7 plus unlocked for $117 directly from Moto and put Lineage on it, no gapps Would love to use thie k51 though if anyone figures it out because it's more waterproof and bigger battery.

Whether device's bootloader is unlockable / device's Android is root-able or not you easily can find out by means of ABB:
Code:
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

Absolutely no of the crap above works at all in any capacity especially sprint. Generic postings like hold volume down and power also doesn't work to go into fastboot so if you guys are following the advice of some of these guys don't because you'll drop more money on a new phone then you will unlocking it some variants verizon is one I think you have to call LG I know I spent 6 hrs on the phone with "tech support" aka "jokes with a screen to read from" to FINALLY get into touch with an engineer who told me the only way "NOW" to unlocked the bootloader is in his office which means it has to be depot to be unlocked which as of this moment lg is not doing that WILL change in the future that was 12/03/2020. Even running external adb with kali linux to hack it broke the bootloader and sends you into an infinite reboot loop

This returns no value on a locked bootloader because even with Dev. Opt. Enables its still read only until bootloader is unlocked this is verified on two carriers k51's sprint and att. However it is unlockable we haven't found it and/or LG has not added this service to their site which is where you will get the info needed for the unlocked.
Oh my. You know you need to do all this from a computer, right? Can't do it in an Android terminal because fastboot commands are only valid in a phone's bootloader environment. And if you didnt know that then rooting and all of the dangers that come with it just isnt for you. But yes, it's rootable. So here you go anyway.
Reboot the phone to download mode.
Install LG's K51 usb drivers, and install adb and fastboot, on your computer.
Open a command prompt and type: fastboot oem unlock
If it does anything other than pat you on the back and tell you it's proud of you and how well you follow instructions, then go back and follow the effing instructions.
Otherwise, type: fastboot reboot.
Download magisk manager.
Do the magisk manager.
Use the LG flash tool on your computer to flash what you just did when you did the magisk manager.
And presto, you're rooted. Or I successfully left out enough info and you dont know how to use Google, leaving your device still not rooted. And thank god for that.
Ive been learning from xda for some time now. Bricked a few phones in my learning curve and tonight i had my first success with my g7, and wrighting this on my new k51. This is my first post and I think that was pretty rude of you to say. This is supposed to be a place to learn, share knowledge, and help those who are less educated. Not look down on people and say crap like that. If he wants to learn even if it takes a couple bricked phones to do it, let him. Either give him the proper procedures or dont say nothing at all. How long did it take you? How many phones? Its taking me quit a while but i am finaly getting somewhere. Keep with it guy. Dont let this dude, or any one else for that matter, bring you down.

Yo Ken,
So your K51 rooted?
If so, maybe you could provide a step by step?
I haven't done this yet but is it verified working? I did a google search came across the method to do the unlocking but it showed it was a failed project?

How To Guide [ROOT][GAPPS] Root and install GApps on stock Edge S/Chinese version

So you got the Edge S and want GApps? Basically you unlock your bootloader, root with Magisk, then install MagiskGApps.
DISCLAIMER: UNLOCKING YOUR BOOTLOADER MAY VOID YOUR WARRANTY, AND DOING ALL THESE THINGS IN THIS GUIDE MAY RESULT IN DAMAGE/BRICKING YOUR PHONE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR PHONE. PROCEED AT YOUR OWN RISK.
1. Unlock the bootloader: that should be doable with their global bootloader unlock website here.
2. Download Lenovo Motoroa Smart Assistant (Rescue and Smart Assistant), and follow its instructions to "rescue" your device. It will lead you to boot into bootloader mode and download the firmware. Find the firmware file via the LMSA's downloads (should have a "show folder" button). You'll need the boot.img file for Magisk.
3. Download Magisk, then follow its instructions. You'll have to copy the boot.img to your device, then use Magisk to patch the boot file, then copy the modified one to your PC.
4. You'll need fastboot. If you don't have it already, you can download the Android SDK platform tools here. Then go into the folder, Shift+Right Click the folder, then "Open Command Prompt" or "Open PowerShell," you should have something close to one of those two. Copy your Magisk modified .img file to that folder, then you'll want to input:
fastboot flash boot [modified .img file]
Once that completes, you should see in large text, "Start" on your phone next to the power button. Press the power button, and it should boot, and you should have root now.
5. Download MagiskGApps to your phone, open Magisk on your phone, click the button that looks like a puzzle piece at the bottom of the screen, "Modules." Click "Install from storage," locate the MagiskGApps file, and install it. After that it will ask you to restart your phone, do that, then you'll just have to be patient as it takes time once its restarted to load everything. You also may need to update some or all of the apps, then you should be able to use the notification to finish setting up the phone with Google Setup.
Thanks to Motorola for making it easy to unlock their bootloaders
Thanks to the whole Magisk team for making an easy, awesome root (and more!)
Thanks to Wacko1805 (and team?) for making MagiskGApps. This is really awesome.

Magisk has a "Magisk Hide" which will allow it to pass SafetyNet, and most things which check on device security will think the device is secure. But unlocking BL and rooting does make the device less secure, and therefore incurs its own risks apart from bricking or damaging the device.

Google Pay works. But according to the Motorola website you should be able to relock the bootloader if yours doesn't work. But there's never any guarantee. If you need your device secure, recommend don't unlock bl or root, or wait to see if there's a root option without bootloader unlock that can be easily undone.

That's not good. Hopefully they can restore it back somehow. With this guide to unlock and flash gapps why would you need to flash G100 though? This seems to be itright now without one of rom developer's releases to get root & apps. For me this is all i would look for. Titanium backup on it and restore.. done until PE rom comes out.

I would think yes, if you flash different firmware, locking the BL would likely cause problems. It's very difficult to do anything w/o unlocked bootloader, except sometimes rooting is doable. That's pretty much the behavior I expect. If they come to this subforum, we might be able to help.

Mine doesn't let me unlock its BL. I've got unlock code from moto and did a factory reset with SIM card in slot 1. After enabling developer mode and debugging the switch still is greyed out. So no chance to unlock it.
Has anyone got an idea what to try now?
Moto support answered yesterday to my request but also no solution since I told them that it doesn't work
Device is not branded. I got it from Amazon so no provider branding.
If this won't be able to be unlocked and rooted I'll have to return it and switch to a Google Pixel.

I had the same issue, you need to factory reset WITH your sim card in the phone, this will let you open the OEM unlock slide thing in the dev mode.
Then once its done you can fastboot and unlock the bootloader.
I did so, maybe I explained not so well. SIM was inserted and then I did factory reset by starting it from settings. After restart it's still the same - switch / unlock slider greyed out.

On my OG Pixel XL, I had to wait 7 days for the slider to become normal. By the time I got around to do it on the Edge S it was about the same time.... could be related
Now as you said that I remember that thingy with another device. Maybe a Xiaomi I think... With that I had to wait several days until the unlock code was delivered.
But there was a message, too, when trying to get it sooner, which said you needed to wait some more time.
Not sure if it's the the same for Moto devices? Then again, when thinking that you experienced the same with a Pixel, too...
Did anyone else make such an experience with his/her g100?

Make sure your on the latest OTA, Lenovo made a mistake on previous versions with the OEM Unlocking function not being enabled. They fixed it in latest ota.
RSA tool said the file I uploaded yesterday is the latest one available (and it's exactly the same as the installed version).
The device was released just a few days ago in Europe. Perhaps they fixed the unlock switch in other regions and still need to fix it in Europe..
Will wait until weekend if they come up with a solution. If not I'm afraid I have to return the device as I need it personally AND professionally, too - I'm field agent, so.... :/

Question TMobile OP9 bootloader unlock process stuck

Hello,
I am trying to convert Tmobile OP9 to Global version and I am stuck at a basic step of getting the oem unlock code when trying to unlock the bootloader.
Details:
1. got my network unlocked from mobbdeep couple of weeks back.
2. Under Settings > "Network Unlock" status shows as unlocked
3. Installed the latest SDK as I am following the guide here to get the bootloader unlocked. When I boot in fastmode and run the oem command it stays at "waiting for device" and returns nothing.
Code:
fastboot oem get_unlock_code
When I run this, device list shows empty
Code:
adb devices
- Enabled USB debugging and stay awake options is checked from what I read on few posts
- When I restart the phone normally and then run "adb devices" it shows my phone listed
- Working on windows machine
What am I doing wrong here ?
TIA !!
PS: attached image shows the device state as Locked
If your phone is SIM unlocked, follow the instructions to convert from T-Mo to global.
Then you'll have the normal OEM unlock in dev options. Then you can just do the fastboot oem unlock and call it good.
Much easier and you don't have to deal with the token. It worked well for me.
I have the global version, not TMobile, so this might not apply
But I had a similar issue with fastboot not recognizing my device, the solution is disabling driver signing in windows and manually updating the driver in device manager
Check the "root OnePlus9" thread.. on page 8 at the bottom there's a guide on how to do it

Thanks for your response.
I tried that earlier assuming the same but it asked me to first flash the unlock token for which I am following the steps
I was however able to get the device listed after manually uninstalling/installing adb drivers

Check in device manager. If you have the yellow triangle on your phone in device manager just download android composite driver and update it through device manager/browse computer/ select unzipped folder and click OK.

That was indeed the issue. I manually uninstalled and installed the drivers which helped and I can now see the device listed and also got the oem unlock code successfully.
I have submitted the form with Tmobile for the unlock token, hopefully that should do it.

I remember doing the same process for OP6T. Some users had mentioned about the issues surfacing and that helped o go back to stock
That reminds, like 6T are there any known issues post converting ?
I remember play services weren't functioning fine as well as there was no google pay. My corporate apps also didnt install due to missing security certificates.
Same applies for OP9 as well ?

I remember doing the same process for OP6T. Some users had mentioned about the issues surfacing and that helped o go back to stock
That reminds, like 6T are there any known issues post converting ?
I remember play services weren't functioning fine as well as there was no google pay. My corporate apps also didnt install due to missing security certificates.
Same applies for OP9 as well ?

You might want to backup your modem partition just in case you want to try the T-Mobile modem. I've heard reports the the AA modem works great, and also that the AA modem sucks, so YMMV

Hey thanks for the heads up. I will
Would infact first go through the conversion steps to go back to Tmo just incase things go south.

If going for root and conversion,don't forget to use partitions manager to back up persist.img and modemst1,modemst2.
Can't stress that enough. This is my second oneplus device messed up in a 3 week time period

Following the guide here, I just performed the bootloader unlock successfully. Per your suggestion, I want to backup the modem files before I proceed any further.
I cant seem to recollect how do I backup the modem files when I did the same conversion for OP6T. Can you please guide me here before I proceed with the next steps.
I tried installing the partitions backup but it wont allow me without root. I vaguely remember that I hadn't rooted my device the last time while backing up these files or is root needed ?
TIA !
You need to root. Rooting is fine and won't affect your modem. While you are there, back up persist, modemst1, modemst2, modem_a, and modem_b. _a and _b should be different versions and you can pick and choose which one you might want to use (or stick with AA)

Can you help me with the steps to root ? Just want to be careful while doing so.
I saw some posts but that was related to the Tmobile OP9Pro(in my case its its Tmo Op9). The boot images were different so I didnt try to play around.
Thanks !
Just try to fastboot boot a magisk patched img and see if it works.
Try https://forum.xda-developers.com/t/root-oneplus-9.4253651/
Don't flash anything, just go to fastboot
Code:
fastboot boot patched_boot.img

Okay did this step.
Downloaded an copied stock image and the boot_patched image provided on the link and copied to my phones internal storage
Also as next step said, rebooted the phone
- went to Magisk app > install > selected boot_patched.img from internal storage
- phone restarted
- When I open the partitions backup app it still shows "device is not rooted" warning
What step did I miss ?

That was indeed the issue. I manually uninstalled and installed the drivers which helped and I can now see the device listed and also got the oem unlock code successfully.
I have submitted the form with Tmobile for the unlock token, hopefully that should do it.
Thanks !

Question How to unlock new Tmo variant with OEM unlock greyed out?

Title pretty much asks it all.
In developer options, OEM unlocking is greyed out. Is there a way to unlock and if so how?

Have you connected to internet? What version of oxygen os are you on? And does it say "connect to the internet or contact your carrier" by the OEM unlocking toggle?
Yes Internet. Oos 11. I tried the T-Mobile app for permanent unlock it failed. Doesn't say anything but "allows the bl to be unlocked" but it's greyed.

Permanent unlock is sim unlocking, has nothing to do with OEM unlocking
Thats great thanks
I got it. Set to midi connection so ADB detects phone.
adb shell
pm disable-user com.qualcomm.qti.uim
Now OEM unlocking is ungreyed
Its a no go. It reveals the option, but fastboot commands ask for a token.
Going to the Oneplus token generator with the correct info (because get oem info worked in fastboot) results in a window that says
"api router invoker request error"
It seems these phones are no longer rootable. Maybe when its paid off tmobile will give me a token.
Any ideas?
"fastboot flashing unlock" asks for token.

Maybe the site down, probably wait a bit, got the same error too
Thanks Ill get all prudent info in a text file. What a pita. I loathe having a new phone and not knowing whether I can root it. So much setting up already.
I tried it again for the heck of it, and now it says "IMEI number has been applied" ...so I guess I wait for the email?
Never got a confirmation or anything, but searches tell me I should get it in a few days to weeks.

i got mine around an hour later after applying mine, maybe check hourly to see if you gotten it or not?
Nothing. Tbh I think Im gonna return this. Its only 128gb version and I was much happier with rooted A32 5G.
Sucks cant even use tasker for fun stuff.
Look through the OP9 forums for the OnePlus Tool..... it helps you get the number you write down to request the unlock code from OnePlus, also it can ungrey the OEM switch
Thanks but I already got that stuff requested. Still no token :-( Been talking to support tho they said they are on it!

OMG !
I have spent 7 hours attempting to unlock my Boot-Loader, and in the desire to prevent any unintended updates, I did not connect my OP9 to the network.
I Think That This Advice Should be Stickied to the front page:
"Unable to toggle OEM unlocking in <Developer Settings> ?"
"Connect to Internet first to see if it's already done !!"
HOWEVER, I still cannot :
Code:
flashboot flashing unlock
FAILED (remote: 'Unrecognized command flashing unlock')

Try ,,,,,,fastboot oem unlock,,,,
Its fastboot flashing unlock and I wouldnt recommend anything but using a token, because the rooting information here is fragmented and outdated.
Request one from oneplus and check back on that page you requested it on. Mine took about 3 days.

I already have that... Hence my confusion.
I'm thinking that there's Just One Little Thing I'm doing wrong here... Can't figure it out..!
Aha. I had been doing it in the wrong order.
Bash:
fastboot devices
fastboot flash cust-unlock unlock_code.bin
fastboot oem unlock
