I am not sure since I am not currently using TWRP on newer devices.

That might be the TWRP message screen showing that you are in fastbootd?

I am not sure why it gave you an option to enable adb since it does not work with fastbootd.

Check if the device is showing up in fastboot.

fastboot devices

Example from my N200 booted into fastbootd.

(Stock system and recovery, rooted with Magisk.)

[ip@lost ip]$ fastboot devices
9d74ba37	fastbootd

If it is, then just fastboot reboot should reboot you into system.

I have not hard-locked an OnePlus lately but, normally holding the power button down will eventually power off or reboot the device.

Might take a minute of holding the button down.

Cheers. :cowboy:

PS.

Since fastboot_d was implemented, changes in Android has moved were it is.

Older (newer) devices is was part of the boot image, then part of the recovery image.
[OnePlus 6T  Guides, News, & Discussion] E4tless:
Yes, so I head the Power Button

I held the Power Button and Volume Down Combo for longer and it did restart the phone, thankfully.

So following threads trying to unlock my Onplus Nord N10 5G T-Mobile version, I noticed that the TWRP sideload and, very recently, your fastbootd request all disconnected the ADB console on my PC.

I already checked both times with the adb/fastboot devices and it returned blanks, other times it gets stuck at 'waiting for response from device' and I have to exit out of cmd.

I'm guessing the issue is with the TWRP recovery itself... I'm thinking of downloading and flashing a new one.

What do you think? Any other/better alternative custom recovery's...

I just need to be able to boot to fastbootd and erase modemst1 and modemst2 in hopes of unlocking the device... that's all I need to achieve right now.
[OnePlus 6T  Guides, News, & Discussion] ipdev:
When booted into fastboot (bootloader) or fastbootd, adb will not work.

Only the fastboot command can connect.

The adb command only connects when booted into an Android environment (system).

Recovery (Stock or Custom) is a mini Android environment.​

---

If starting Sideload in TWRP kills the adb connection..

That is a problem since adb is required to do an adb sideload. 🙃

I have run into this on an older device that used a hack to fix MTP in TWRP.

It worked for years but, now breaks sideload. The maintainer removed the hack to fix sideload but, MTP is broken again.​

---

I would first backup the partitions.

Boot into TWRP and pull the partitions to you computer.

You can find the actual partition by looking in the by-name directory under /dev/block/

It might be a few directories in but it will be there.

Example from a Pixel 3a running Lineage 19.1.

[ip@lost ip]$ adb shell ls -la /dev/block/by-name/ | grep 'modemst'
lrwxrwxrwx 1 root root 21 1973-06-25 15:17 modemst1 -> /dev/block/mmcblk0p46
lrwxrwxrwx 1 root root 21 1973-06-25 15:17 modemst2 -> /dev/block/mmcblk0p47
[ip@lost ip]$ adb pull /dev/block/mmcblk0p46 modemst1.img
/dev/block/mmcblk0p46: 1 file pulled, 0 skipped. 18.1 MB/s (2097152 bytes in 0.110s)
[ip@lost ip]$

This will pull the partition into a file named modemst1.img you can name the image file MyOriginalmst1.img or something else if you want.

Do the same for modemst2,

This way if something is broken, you can flash your backup back to modemst.

Then

Restore the stock recovery and reboot.

Reboot into fastbootd and see what happens. 🙃

If you need a custom recovery, you can always flash TWRP again (newest version normally suggested).

Cheers. :cowboy:
[OnePlus 6T  Guides, News, & Discussion] E4tless:
Really appreciate your assistance.

This is a massive edit of my reply. I figured out fastbootd is whatever comes up after you issue 'fastboot reboot fastboot'. On the phone it presents you with a dialogue to choose language in Chinese, Japanese and English... then after that some more options to choose. I kept following those in the past and ended up rebooting into normal bootloader.

The key was for me just not doing anything after I gave 'fastboot reboot fastboot' command and go on straight to issue the next commands...

Anyways, on my 1+ Nord N10 5G T-Mobile variant, which I have bootloader unlocked, rooted and flashed Global Rom = Oxygen OS 10.5.11 BE86AA, I successfully erased/deleted modemst1 and modemst2, but all I'm seeing is that there is no pop-up again showing that says the phone is locked and blah blah blah...

However, the sim icon remains marked with an x and doesn't work... In other words: It appears phone is still locked after erasing modemst1 and modemst2 :).

What should I do now?

Erase is not allowed for Critical Partitions؟

help please
[OnePlus 6T  Guides, News, & Discussion] E4tless:
Execute fastboot reboot fastboot, then do nothing else after the command executes on the phone (!important) and just issue erase commands from adb.

Like I learnt and tested, erasing critical partitions can only be done within fastbootd mode = fastboot reboot fastboot.

NB: Don't follow any on-screen prompts on the phone, simply ignore the phone and just proceed to execute erase commands from adb terminal.

Having the OEM/non-twrp & other custom recovery images help a lot, unless fastbootd works on your custom recovery.
[OnePlus 6T  Guides, News, & Discussion] DominatorOne:
Hello, sorry to bump this old thread, I just did this yesterday and it worked flawlessly, the only question that I have now is how to I get back to Android 11 since when I used the MSM tool to flash the international ROM I got downgraded to Android 9 and If I try to check for system updates it says that I have the latest version. Personally I wouldn't mind to stick to A9 but I need Slack on this phone and it seems to be that it doesn't work on this Android version.

Is it safe to use the Oxygen Updater to perform a manual upgrade? and if doing so, will the phone stay Unlocked and would it be any issues when trying to update the phone with the bootloader that is unlocked now? Thanks in advance.
[OnePlus 6T  Guides, News, & Discussion] BiggRoy66:
Why doesn't anyone make a short video and show how it is done for people who have very little knowledge of how to do these processes? Come on it's nice to read all these success stories from every one but I don't know more than half of what everyone is talking about.

I cannot express my level of gratitude! I know you've likely long forgotten this special gem of a thread but it shines brightly to this day! I have had to use this phone without a network for many years since it came out. I got fed up and decided I can get this done...viola. Thank you once again.

I've finally did the process and it WORKS PERFECTLY, sim unlocked, no ime issue... data working correctly, everything works perfect.

I'm very excited, let me get a refund from cellunlocker and donate you some money

Could I lock bootloader again?

Thank you nika_bego
[OnePlus 6T  Guides, News, & Discussion] :
Well damn that's even easier
[OnePlus 6T  Guides, News, & Discussion] kramer987:
lol yep. significantly easier than what i used back in November
[OnePlus 6T  Guides, News, & Discussion] tech_head:
This is similar to how SIM unlock was gained on the Sprint Essential PH-1.

The modem and setting files were copied from a SIM unlocked version. This unlocked the SIM on the Sprint version.

Sprint was making people wait months and giving them a hard time even after the device was paid and the waiting period was over.

Good job.
[OnePlus 6T  Guides, News, & Discussion] ecompton59:
Moto z had a magisk mod to do this also but just need to have msm tool to recover just incase
[OnePlus 6T  Guides, News, & Discussion] kramer987:
that's exactly the method that was used in the case i am referring to from November
[OnePlus 6T  Guides, News, & Discussion] Caltinpla:
Yeah, I remember you back then;). We both had hard times getting our Essential phones unlocked after the 50 damn days waiting period over. I had to contact Sprint customer relations VP to get it resolved. What a nightmare!!! Never Sprint again!!! I still have it though but gave it to my son and he likes it.
[OnePlus 6T  Guides, News, & Discussion] :
If u guys try the TMobile unlock app it still says network locked, but if u check under engineer codes simlock will now say off. Trying to do this backwards to see if we can relock,, just for kicks

Edit.. yes if u wish for some strange reason to re simlock your phone, reboot bootloader and

fastboot flash modemst1 modemst1.bin

Then same command but with 2 for the second one..

This is after backing it up to an external source somewhere after dd'ing your modemst1 and 2

Then reboot, simlock is back on. And then u can do this back and forth furthermore, thanks nika
[OnePlus 6T  Guides, News, & Discussion] :
If you don't want modifications in system you can lock bootloader or just left as is

Cool it's way faster than any service for unlock :D
[OnePlus 6T  Guides, News, & Discussion] Scott:
Your not deleting the modem. Your deleting the storage of the modem, modemST.

Its all over the internet. No for real. Just google modemst1 or modemst2. I did when I saw this and realized he is correct with what he posted.

https://www.theandroidsoul.com/fix-...d-wifibluetooth-issues-restoring-twrp-backup/

Or better yet.... https://www.google.com/search?q=mod...0j69i60j0l2.1471j0j4&sourceid=chrome&ie=UTF-8

This!

If the T-Mobile App says your still locked, could you tell me if Developer Options allow Bootloader unlock?

The only reason I care is I want to run the T-Mobile ROM but maintain root.
[OnePlus 6T  Guides, News, & Discussion] XJonathanX2:

Yep. As soon as the 6T was announced with Verizon compatibility; it was on the shopping list.

I bought mine unlocked, so not carrier drama.

I sold the Essential on Swappa for more than I paid.
[OnePlus 6T  Guides, News, & Discussion] XJonathanX2:

[OnePlus 6T  Guides, News, & Discussion] cangri87:
This worked great! Just tested it with a AT&T sim and low and behold i had service.

I am wondering now, if i revert back to stock if it will remain sim unlocked or will the flashing back to factory

rewrite the modemst files?
[OnePlus 6T  Guides, News, & Discussion] pyrorob:
Has anyone thought of comparing dumps of a before and after using a hex editor or beyond compare or similar utility? Would be best if someone compared a dump of an proper sim unlocked device, but it might be interesting to compare using this method as to see if anything is written to those partitions after deletion..
[OnePlus 6T  Guides, News, & Discussion] :
If you flash stock it will be sim unlocked you need modemst1 and modemst2 backup after sim unlock you can flash this files and it will be sim locked again

---------- Post added at 08:09 PM ---------- Previous post was at 08:06 PM ----------

Has anyone tried this...

Convert to international version.

Root, etc.

Wipe ModemSt1/2

Flash T-Mobile back to the device.

If you have done this please let me know if you can bootloader unlock the bootloader with the T-Mobile software applied?
[OnePlus 6T  Guides, News, & Discussion] Jrod333:
haven't but i am up for anything... maybe
[OnePlus 6T  Guides, News, & Discussion] Scott:
Decided to try it now. Figured whats the worst that can happen. I am used to my device being in disarray from my dev years. This will atleast give me something to do. I know I cant be the only one who wonders... Just for the sake of wondering...

---------- Post added at 12:44 AM ---------- Previous post was at 12:41 AM ----------

Yay it works! The T-Mobile Unlock App shows unlocked after clearing the modemst1/2.

I did this using the fastboot method. Now I am going to flash the complete stock T-Mobile MSM Package. Then I will report how it acts then.
[OnePlus 6T  Guides, News, & Discussion] Scott:
I can confirm that after restoring to the stock T-Mobile MSM, the bootloader is unlockable. You do not need to wait the 40 Day Sim Unlock time frame.

This is great. Someone should out all this in an T-Mobile Tips / Tricks thread.

Here are condensed version of the steps I took.

Flash international ROM using MSM Tool

Unlock bootloader

Erase modemst1/2

MSM back to T-Mobile

Fastboot to get OEM token and submit on OnePlus site.

Let all OTA's take place as they should

Wait 7 days and unlock bootloader with full T-Mobile software "tweaks"

This method will also work for people still on a payment plan and have not paid off the phone. They can get unlock token even though they are still paying on device otherwise device would have to be paid off before the 40 day period even begins.

In a week I will have the unlock code... Two weeks faster than I would have. I wish I just tried this first instead of trying to ride out the 40 days. The funny thing is, it doesn't matter because I will more than likely end up running the latest beta anyways. I guess its just the thought of having a fully unlocked phone with no strings.

[OnePlus 6T  Guides, News, & Discussion] :
Yes I said I did this, u still will need unlock bin but u can at least request it now

---------- Post added at 05:56 PM ---------- Previous post was at 05:50 PM ----------

Bootloader unlock and sim unlock are entirely different things. And this already has been verified it is a work around to turn off the T-Mobile sim lock

After doing so, u can *#808 and check sim lock status and it will show off. Then u can reflash the modemst1 and 2

, If u backed them up, and then again check the status and it shows locked. I have said and documented all of this in multiple threads. After erasing modemst1 and 2 u can flash the tmo specific msm tool and then test the T-Mobile unlock app and them it shows sim and network unlocked. Now u don't need tmo to have them sim unlock it and request the 7 day unlock bin. U guys are asking about things that have long been figured out and the most recent thing being this specific thread and have already iterated, stop waiting to pay things off to get sim unlocked, turn it off using this method, use tmo specific msm tool And then fastboot oem get_unlock_code get code and I'm, go to oneplus's unlock bootloader site, enter info, wait 7 days. I'll have mine tomorrow. My second one.
[OnePlus 6T  Guides, News, & Discussion] Jrod333:
excuse my lack of knowledge on the subject i am following along the best i can, are you doing all this to try and unlock the boot loader or sim ( not sure the difference). As i have unlocked my bootloader in the t-mobile 6t. I have a a hard time following on this forum at times because of the layout and i do not usually join in on things like this. If in fact you are just tying to unlock, i did not have to do all of that or wait for pins, codes, or T mobile at all. I did in fact do exactly as i stated i did. I believe i saw that somebody called me a lier..not sure why. I do not spend my days getting online and trying to lie to strangers as it has no benefit to me what so ever. I am here to learn more then what i know now and if i, somehow do something by sheer luck, i feel the need to share as i know how freaking frustrating it is to try and get a task done. Now that being said, you seem to know alot more then me so maybe you are trying to do something else? My T mobile 6T is ruining the international software and is now rooted (magisk). I do not have TWRP on it as i hear its not working to well. I may not know a ton, but one thing i do is spend hour apon hours reading and trying different things. I am not worried about my phone as i have screwed it or "bricked" "soft-brick" or what ever we call it so many times i cant count but i have every time got it back running. One day this might not be the case for me but seems like no matter what i do to it as long as i have the original software to re flash and start over i am good. So long story short, not saying you should listen or try any of the things i do but are you trying to accomplish the same or I am i totally not following and your trying to do something else? Thank you in advance for your patients with me.

[OnePlus 6T  Guides, News, & Discussion] :
Yeah once u get the bin, in 7 days, u flash it, unlock bootloader that way, then flash custom kernels whatever, root and keep stock tmo software. I should have mine right now actually, I forgot lol. Its exactly 7 days.

Worth noting that even after getting the unlock bin, if u happen to switch over to Intl firmware and go back to tmo. U must flash unlock bin again, so keep it handy.

My exact steps and soon to be steps. Just waiting on that unlock.bin. Someone told me in this thread or another that whatever code you get will work with any T-Mo device. Have you heard of this?

Sorry to go so far off topic but in all it is related. In a way...
[OnePlus 6T  Guides, News, & Discussion] :
It is untrue that any code works for any tmo device. They are dependent on individual device imei, imsi, and some other variables. And I will be sure to link you when I get it done.
