OnePlus 6T - Can't unlock bootloader nor get into Android - OnePlus 6T Questions & Answers

My OP6T had Ubuntu Touch (equivalent to Android 9) installed on it. When it broke, I tried to flash TWRP (version 3.3.1) to clear and reinstall Ubuntu Touch. For some reason it wouldn't boot, so I foolishly decided to flash TWRP onto every single partition. This only succeeded in breaking recovery mode. Following some advice I used the 6T MsmDownloadTool v4.0.58 (OOS v9.0.11), which fixed recovery mode, but not Android - it just showed the booting animation in a infinite loop (bootloop).
I've attached an image I found online showing the screen: bootloop
The issue is that I cannot flash in fastboot mode as the bootloader was relocked by MsmDownloadTool, *and* I cannot get into Android to enable OEM mode/USB debugging. I seem to have encountered a paradox where fastboot mode requires the permissions to be enabled in Android, but I can't boot to Android to enable those permissions, nor can I flash anything else to fix Android.
Is this possible to solve?

You can try booting with the twrp.img. "fastboot boot name.img" using that ADB command. If that does not work the only other option is to completely retore your phone using msmdownload tool. This method will also depend on whether you have the international version or the T-Mobile version as there are different approaches depending on the type of phone. Read and study carefully how to proceed. If the msm tool does not work I'm pretty damn sure there are no other options.

He can't boot into anything with bootloader locked. This is why msm tool sucks and people should stop recommending it for any little problem.

Only option now is to use msm tool again and hopefully get something working

Even with the bootloader locked you still should be able to boot the recocery image.

I have the 6T and 7T Pro. When I messed up my 6T my only hope was the msmdownloadtool. But make sure it's the right one.

When I had to use the msm download tool it did lock the bootloader. But I was able to unloack it again from the ADB command prompt at the bootloader screen by typing fastboot oem unlock. But this can only be done if it is set in developer options.
I spent alot of time trying to figure it out but later found outthat I was using the wrong msm tool.
Good luck. I hope you get it and running again because the 6T is still a very good phone.

Thank you! And yes, I tried that command but it is probably unset in the developer options (which I cannot reach, as Android isn't working anymore). I guess I'm using the incorrect version - how do you identify the correct one? I think I've used both the T-Mobile one and the other. I don't think the phone is T-Mobile, but I'm not sure how to identify whether it is or not.

It is very easy to convert a t-mobile variant to the international version. If you bought the phone used you would not know. One tell tale sign could be if you sim card holder supports either one or 2 sims. But that's not a sure way either because you can buy a replacement sim card holder. The fastet was would be to look up the IMEI # and see what variant of the 6 you have.
As for the msm tool you would needd a modified version of that tool. You first use it to downgrade to Android 9. Then you have to upgrade that verion of android 9 to a slightly higher version before you are able to fully upgrade feely to 10 than 11 if you wanted.
If you have the international version pretty much and version of the msm tool would work but a modified version would be best.
However, the first step is to find out which variant you have.
When you used the msmdownload tool which version did you use, and did it finish the job ?

If you have the t-mobile vesion there is a thread on here that gives you step by step instructions to convert from t-mobile to international along with the links to download the software. And even the modified version will know what variant you have simply by not working.

If you are able to get into the bootloader than you have a great chance of fixing your phone. Your phone is bootlooping so that tells me you can access the bootloader screen.

When I bricked mine I thought it was gone forever, I spent several days working on it but I was able to restore it. But I would never use the ubuntu rom on any phone that I care for.

When you are at this level it is very important you proceed with caution and don't just start flashing anything you can find. It will nake matters much worse.

No. Not without an unlocked bootloader. But booting into twrp would give you the ability to flash a ROM tho.

That's what I meant. Flash a ROM from twrp. Ok so if that works this guy can fix everything from there. Gonna be a hassle tho. Instead of rebooting to recovery I think you would have to shut off phone and fastboot boot back into twrp to change slots right?

Somehow I feel like that won't work but I'm not locking my bootloader to test it

As far as I can tell there's no way to flash TWRP without unlocking the bootloader. And there doesn't seem to be any way to do that without getting into Android. And I can't get into Android...
Someone else suggested using this tool (https://github.com/bkerler/edl) as a last-ditch attempt. I'm going to give it a try and hope for the best!
Thank you both for your suggestions.

2017g DFU mode investigation

This thread is for users who have a 2017g model that is stuck in DFU mode.
If you would like to assist in the investigation, please reply here. I'll be sending links to test programs to try to diagnose and repair devices.
With any luck, we can get the devices back to normal within a few days.
Reserved
I had this problem, but luckily I could send it back and get a new one on warranty. I was very careful when unlocking the new one ?
Skickat från min ZTE A2017G via Tapatalk
Can more people who are stuck in DFU mode PLEASE contact tennear? I worked with him before and he really knows what he is doing. He's the only one who I think could be able to help you restore your device to working state.
Please help him, so A2017g users like me know they have a trick up their sleeve in the case the BL unlock goes awfully wrong
Thank you.
@tennear keep us updated. I'm planning to give up root in order to get this week's B08 update and i'm not sure if flashing the system with twrp will go smoothly.
Thank you for you work and dedication to help other people.
I have two people that are able to help now. But more is always better. If you have a G model and you can access DFU (regardless if you are bricked or not), you can help test. Linux is my preferred OS, but I can also build for Win64 if needed.

If you are Lock bootloader and have TWRP you CAN flash B08 , just need to mod. The updater_script in other for the B08 to be install, but YOU WON'T BE ABLE TO ROOT unless you unlock bootloader and I'll be posting something about that later today or coming days.

I'm rooted without unlocking bootloader (tenfar's method).
So you are saying I can flash the upcoming update safely from TWRP by editing updater script and removing getprop & assertprop lines from it?
I also have system modifications.

Ok, I don't want to go off topic here, but YES you'll need to edit updater_script and look and bookmark if possible my thread about Updates ,I'll be posting B08 as soon the full update hits ZTE site. If you want to talk about Updates post there , so we can keep this thread on topic.
I agree. See you there.

I have a G model and I am using Linux (based on ArchLinux). I can use Windows 10 if needed, so OS should not be a problem.
So if you need some testing, I can help
Hi, I would love to help,
I have a G model and I have TWRP and unlocked bootloader but u can access DFU mode
I am using windows
I'm afraid that I have not been successful getting out of DFU mode. I have tried several things, but the device refuses to switch into EDL mode.
According to the user who has a bricked device, he got bricked by running "axon7backup -d" without any image files present. The tool wrote something to both boot and recovery partitions. I don't know what that something is -- zeros, random data, ... who knows.
So it seems that if you are careful and only flash recovery properly, the device should not brick. But I cannot test -- someone else will need to confirm.
Now that this investigation is concluded, I will be posting my own tool shortly.
Always remember: to avoid bricking your device, never flash both boot and recovery at the same time.
^^Is there even a reason to flash the boot/kernel? The main reason why most of us would use the axonbackup tool is to flash twrp.

The only reason why tenfar had the tool to Flash boot is because he had the boot sign and pre-rooted for Lock bootloader units.
^^Got it. I thought about keeping the BL locked, but decided unlocking it would cause fewer headaches and be less restrictive.
That is correct, there is no real reason to flash your boot partition now that the images provided by tenfar are not compatible with the latest updates from ZTE.
However, the real danger remains: if you run "axon7backup -d" with no files to write, it is reported to write bad data over both boot and recovery and brick your device.
I highly recommend using my tool instead. I can guarantee that it will never write both boot and recovery in the same session.

The command help indicates -d is to dump only. My understanding is nothing is written to the phone when reading from it? Are you saying that's not the case?

Yes, that is what I am saying. According to a PM that I received, the user ran "axon7backup -d" without any other files in the directory. The tool flashed something to both boot and recovery partitions. No idea what it flashed. But then the device was bricked. And because 2017g cannot enter EDL mode directly, there is no way to unbrick.
hi i have china version of axon 7 A2017 and have the same problem with my device (stuck in dfu mode after Flashing SuperSU).Will there ever be a way to fix this problem? I am depered :crying:.

Total idiot here needs help rooting.

Hey everyone, I'm currently on B29, non-rooted and locked bootloader.
I would like to root and make my up to stock 7.1.1. The issue I'm having, is that there is an absolute ton of conflicting info and ways to do things that I'm just not sure at all how to proceed.
What I've tried so far was starting with this guide: https://forum.xda-developers.com/axon-7/how-to/newbies-guide-to-unlocking-rooting-axon-t3496234. But the tool from step three wouldn't download and the hosting site threw a ton of popups and redirects at me (yes, I have uBlock).
Then continuing through that same thread I found this tool https://forum.xda-developers.com/axon-7/development/axon7tool-flash-backup-boot-recovery-t3514254 that is apparently safer, but I have no idea how to use it.
Then I started hearing about this EDL mode stuff https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514 which I attempted to do when I tried the Axon7Toolkit yesterday, but my phone just wouldn't go into EDL mode (or I just had no idea how to tell if it was or not) and the MiFlash thing didn't do anything.
So my real questions are:
1: Which version of TWRP and SuperSU do I need?
2: How do I unlock the bootloader?
3: What steps should I take so that I eventually end up rooted on stock 7.1.1 (currently still on B29)?
Thanks!
umm shouldn't this go on questions and answers?
Just one thing: You mostly can't tell if your phone is in EDL mode. Some axons will turn the notif light red, some will not do s**t, like mine. Just do whatever the guide says. On A2017G you use "adb reboot edl" and the phone just goes into EDL mode. After that you have to use axon7tool but I'm not sure if it works for nougat...
If the phone is not on EDL mode then the worst thing that can happen is that you get an error. Axon7tool doesn't do anything unless the phone is on EDL, so you pretty much can't mess up

Sorry, I thought it would go here because it was a question about the guides. I'm not sure if a mod would move this but I don't think I should repost the same question in another section?
But yeah, about the EDL, I have the U and I ran "adb reboot edl" but MiFlash didn't see anything and it wasn't showing up when I did "adb devices" so I wasn't sure what was going on. Do you have any guides or anything you'd recommend?

No access with adb or fastboot in edl mode. It' strictly for use with low level tools like miflash. Your environment will make the difference. I couldn't get miflash on my main pc (win8/x64) to see the device. Likely an issue of drivers even through the proper driver is installed, and phone is showing up properly in device mgr. I used a spare pc with a relatively fresh win10/x64 install. Miflash saw the phone right away.
Also, for edl mode, my u model will just flash the led once then go blank.
To achieve your goal, easiest to probably just unlock the bootloader with the B29, then mess around with updating to latest.

Okay thanks, I'll give it a go again. Would you be able to clarify which version of TWRP I should use? I'm thinking 3.0.2-0 but I've seen other guides mention different versions and other people say the wrong version is going to be a massive headache.
For the initial unlocking, you'll have to use the signed twrp. I don't recall the exact version, but whatever is included in the unlock thread. Once unlocked, then you can flash the latest 3.1.something.

Okay thanks. As for the rest, am I correct in my understanding that I need to:
First: Use Axon7tool to flash TWRP https://forum.xda-developers.com/axon-7/development/axon7tool-flash-backup-boot-recovery-t3514254
Second: Unlock bootloader
Third: flash the official 7.1.1
Hmm you could use a7tool to flash TWRP, then install the twrp app and upgrade to 3.1 or whatever, and then get to nougat after some backups. I'm not sure but I think tenfar's twrp FUBAR'd some partitions when you tried to backup
Okay thanks. I think I'll give it a rest for today, I've been scouring threads since yesterday trying to get a clear picture of what to do. I think I'll spend the week researching further and give it a go next weekend.
I just miss having AdAway and CF Lumen installed on my phone. And I really want to give Substratum a try.
Thanks for all the tips and info!
Hang in there. You are on the right track. The edl thing can take a few attempts to get recognized.
Did you try the toolkit? Same as using miflash but he has direct downloads to all the necessary drivers and tools along with instructions.

There are people who are reporting that the drivers that I provide in the toolkit do not work and therefore MiFlash fails to flash packages. I am going to use new drivers in the next version(the drivers that come with the stock ROM) and then the OP should test it.
If you have to use axon7tool then you might find this useful

Can you try these drivers: http://drivers.softpedia.com/get/MOBILES/Others/ZTE-Handset-USB-Driver-52066111.shtml
Then test the option again and see if MiFlash will detect your device? Thank you.
Just make sure after you install them you go to C:\Windows and delete adb.exe and AdbWinApi.dll otherwise there will be two conflicting adb versions which will cause the toolkit to indefinitely hang when checking adb connectivity.

@CookedBooks I have great news for you: Thanks to one of my testers I have fixed the MiFlash issue. The problem was not with the drivers, but with MiFlash itself. So the solution was an EARLIER VERSION of MiFlash!! The next version of the toolkit will utilize the earlier version so I should no longer have to deal with this issue! Huzzahh!

LG V20 bricked/bootlooping/bootloader re-locked. How to fix?

Hi all -
I have two US996 phones.
Luckily, my primary phone is fine (rooted stock Oreo ROM)
The "backup" phone was previously bootloader-unlocked and also had TWRP and a stock-rooted Oreo ROM on it - but not yet set up; it booted to the welcome/setup routine.
Well, I did a "full" Nandroid backup of my primary phone (TWRP 3.3.1.0) using the beta feature supposedly allowing backup of data as well as the internal storage and wanted to see if it really did fully restore the phone without need for re-entering all of the passwords and other info for all of the apps. So, I tried to restore it to my backup phone.
Well...I screwed up and apparently didn't do an adequate wipe before flashing. Now, the backup phone is bootlooping with a message saying something like "your phone failed a security test and will not boot". I am not able to get into recovery at all.
I am able to get into fastboot mode, and on "fastboot getvar all", I see that the bootloader has been re-locked!! So, of course, trying to unlock it via fastboot doesn't work, since I am not able to get into developer mode to re-enable OEM unlock...any way to re-unlock it and get into TWRP?
Looked at Medusa Flasher, which is supposedly free (1.1.0.1) but when I try to use it I get "card not found" and it won't open, and the file needed to fix this isn't available. It also appears that it's only good for Sony and HTC phones anyway, and some serious hardware dissection is necessary.
Any help would be appreciated!
Thanks in advance.

Flashing a kdz would be your best option right now. It's safer to start from a rock-solid base

Flashed the Stock Oreo KDZ. Thanks! phone boots now....but I can't unlock the bootloader in the usual way (using the unlock.bin file from LG) because somehow the IMEI number got nulled - all zeroes.
Edit:
Got the IMEI fixed with this method: https://forum.xda-developers.com/v20/help/us996-imei-null-0s-how-fix-t3876980 - and now the bootloader magically became unlocked.
Now to flash TWRP and a rooted image and all should be well.
Thanks again, Landloord!

Can you send me your unlock.bin, looking to try something crazy on my H910

Sure
Hmmmm....couldn't find the file anywhere on my phone or the computer. I unlocked the bootloader on that phone when I first got it four years ago.

Bricked my Chinese OP6t (A6010) and not sure what to do. Help??

I was trying to help a friend out by installing the international OS on his new OP6T (A6010) because I know a friend who did it a year or two ago and it worked perfectly. We thought it would work out but I couldn't get the firmware to install using the normal system update--it said that the firmware was lower than the currently installed firmware and therefore couldn't be installed.
So, I tried downgrading using the msm tool (I didn't realize the Chinese version was different...) and now it is stuck in a boot loop saying "build version and HW version is not match!"
What options do I have here? I didn't install TWRP (I was going to but tried the MSM tool because people were recommending it on many other sites...but were only talking about Tmobile and Global variants so I didn't realize Chinese was an entirely separate one).
Is there any way to fix this?
You can get it into fastboot right? I'd push the latest official fastboot ROM into it via ADB.

No, when I hold any combination of buttons, it gives me the error message. I can't do anything with it at the moment.
I got it to flash "fastboot mode" for a moment, but then the error message went up again and black screen.
That's weird, fastboot should be coming up before it tries to load the OS, you're going to be left with reflashing (in your case) HydrogenOS via download mode and MSM.

Thank you for the information here with this. Are all msm things specific to certain firmwares or is it possible to throw a firmware into an msm thing? I'm not sure about this one yet.
I have a A6010 I have used this to go back to Android 9 with out issue.

Thank you for your help here.
Unfortunately I keep getting the same message again and again in all of the msm tools I've tried: images do not match with the phone.
I'm not sure how I've done it but I've messed it up badly and now not sure how to fix it.

You're going into download mode correctly right? Holding BOTH Vol buttons while then plugging into the USB cable thats already in your comp?

Yeah, I was able to get it recognized by the computer and the msm software. It was just not accepting it.
I actually finally got it to work, though, but using the patched version of the msm tool that Tmobile users were using to install the international firmware, because it ignores the check for hardware/firmware matching and just forces the firmware on there.
It took two different msm tools/firmwares but finally it worked out. It was an incredibly relieving sight to see it boot up and not immediately go into the same bootloop again.
Glad to see you got it going.
Good day, please I got into the same issue of hardbrick on my oneplus 6t chinese variant. Please would you be kind enough to give a break down on how you got it to work. And were you able to finally install Oxygen OS?

Is my Mi 9t bricked?

Hello. I recently tried to flash the latest fastboot global rom which included locking the bootloader. I used the latest miflash unlock program and everything went well and displayed the green "successful' when it was done. But when I rebooted to the system it loaded directly into stock recovery and boot loops by itself, restart>recovery>restart>recovery etc. It also displays at the bottom of the recovery screen "This MIUI version can't be installed this devise' but I'm sure I flashed the right one.
Now I don't know what to do. If I try to reunlock the bootloader it doesn't go through because I haven't linked my account to the phone (and cant do that because it wont boot up properly). I've tried wiping data in recovery but that doesn't change anything. I can however boot the phone into fastboot and also ADB but I don't know what to do from there. If I try to erase the data via fastboot I get an error saying it can't do that on a locked devise.
So I'm really stuck here and if someone knows what I can do (if anything) I would really appreciate your help.

Unfortunately, classical case to seek a paid EDL support
Btw, I don't know did the ROM really forced relocking BL or you didn't pay attention - there was an option in MiFlash to avoid relocking BL (unfortunately, by default it is enabled and many users then come to the same situation and have to seek for and pay EDL support, if anything goes wrong while flashing the ROM - one must disable relocking BL to stay on the safe side)
You should look around XDA if you can find somebody (it's not allowed to advertise, hence most posts would be deleted) or ask on Telegram or similarly

Hi thank you for your reply. I wanted to lock the bootloader as I was going to sell the phone and wanted it all back to stock standard. What does EDL do exactly?

Please google about
It's very deep flashing. Something like how they flash the phones when they are assembled - they have to flash Bootloader and everything

Hey, just to follow up. I managed to get it back up and running from someone with EDL support.
