Locked in fastboot mode after sideloading Lineage OS - OnePlus 6T Questions & Answers

I was running on OOS 10.3 rooted with Magisk and flashed TWRP.
I tried to install Lineage OS 16 (the last version from the official website), but after sideloading it and the superSU file in TWRP I could only reboot in the Lineage recovery mode. I tried to flash a unofficial version of Lineage 17 but still not working, the Lineage recovery mode just became rainbow colored. Then I tried to do a factory reset and flash an OOS and since then I have no more access to the recovery mode and the only thing I have when I try to access it or when I turn on the phone is the unlocked boot loader message. I can only access the fastboot mode. Sometimes when I turn it on, I also have the Qualcomm Crashdump message, but nor every time.
I read about MSM, but I'm running on mac OS... Any ideas of solutions I can try with mac terminal?
Thanks for your help

Fastboot ROM. It's available in the Guides Section and the Instructions are pretty straightforward. You can Google "OP6T Fastboot ROM". Also, from the looks of it, you didn't flash LOS Correctly.

I fastbooted the original ROM and installed TWRP back. Then I used TWRP to install LOS from a zip file. Basically I followed OhioYJ's instructions on his comment above.

HELP No recovery, usb not recognized

Its a shame.
7 years unlocking bootloaders, installing CWM or TWRP or Philz recovery, flashing rom after rom, not even one device bricked, and today, i messed up, i hope its not bad.
So the short version of what i did is that i flashed twrp.img trough and older version of twrp and now it wont boot into twrp, it says that it failed to verify the recovery image or something like that, and my laptop wont recognize the cellphone, the cellphone boots into the latest Havoc rom but without Gapps and without root because i did not install it beforehand, when in bootloader mode it just says that it could not recognize the device.
The long version is that i had Resurrection Remix, obviously an unlock bootloader, magisk etc... everything was fine until today that i tried to install Havoc, the installation went well but i found out that ambient display was not working, someone told me that the previous version of Havoc did not had that problem so i tried to flash it but it bootlooped for like 1hr, so i read that the version of TWRP provided by the OP was the way to get it to work, i downloaded the .img file and flashed it trough TWRP and tried to install Havoc again but i was stuck in a bootloop, so i flashed the latest Havoc build so i could download the latest version of twrp, i did not flash Gapps or Magisk because i was going to re flash the rom and then flash Gapps and magisk, so i downloaded TWRP and flashed trough TWRP and thats when the sh$& hit the fan, now it wont boot into TRWP and my laptop wont recognize the device, neither on android nor in bootloader mode.
So, thank you guys in advance for your help, tomorrow im going to try on a computer at my work and see if its my computer and if not, well, ill have to se what you geniuses come up with. thank you so much again.
Info:
Rom build number: opm6.171017.030.h1 or 20180811 android 8.1.0
TWRP: i started with 3.2.2-0 then i downgraded to 3.2.1-0 and the one that messed up everything was 3.2.3-0
By the way, I have a full twrp backup of when my phone was stock, (but no way to use it) T_T

Unlocking bootloader on Orea update?

I've read around that unlocking the bootloader on the axon 7 with the orea update (B04 on A2017G) isn't gonna work and that I need to roll back to nougat (7.1) and then unlock the bootloader that way and then install TWRP.
I'm a noob and I need some help. All I want is android pie and lineage os 16 on top. So could you guys link me to some easy to follow guides on how to get pie and LOS16?
But first I need to understand why I can't just use ADB right now on the oreo axon 7 and get an unlocked bootloader. Why do I have to roll back to nougat?

You're correct on that statement.
You can't unlock the bootloader on Oreo because there is no fastboot support with the Oreo updates. ZTE basically broke another thing. You'll need to EDL flash Nougat 7.1 and then use the EDL Tool or the A7 Toolkit to unlock the bootloader. Afterwards, you can follow the instructions in the LineageOS 16 thread, and flash in this order:
• Flash universal bootstack (Los15.1v2Universal)
• Flash the A2017G Modem
• Flash LOS16 zip
• Flash GApps and/or Magisk
• Reboot to system.
If you get an error whilst trying to flash LOS16 zip, just try flashing it again.
All the guides in the Guides section are outdated.

Thanks for replying when nobody else did. Since this post was a bit old I went ahead and unlocked the bootloader and installed TWRP with magisk, thinking that I could install Lineage later and first I should obtain root. So I installed magisk through TWRP but now whenever I reboot it just goes straight to TWRP and I don't know how to boot into the phone. Any idea about how I can exit twrp?

Magisk doesn't work at all on stock roms unless you use a work-around. The phone not booting is because of that.
For the work-around, check out this thread:
https://forum.xda-developers.com/axon-7/development/kernel-magisk-17-stock-roms-t3856809
BTW, I'm not sure if this works, I've never tried it. The thread is also a bit old.

could it be a possibility that if I reinstall nougat 7.1 on the phone through TWRP, I'd be able to boot? Or does rooting with magisk completely disable us from installing stock roms without some sort of workaround?
My reasoning is that if the rom installs successfully then I would have booted with magisk in magisk manager and root. Maybe my rom got deleted during this process.

Magisk just prevents the phone from booting. It doesn't delete the rom. If you look in topjohnwu's GitHub page for Magisk, you'll find Magisk Uninstaller right next to where you download Magisk from. Download the Magisk Installer zip, move it over to your phone, and then flash it in TWRP. It'll remove Magisk and you'll be able to boot into your rom again.

Ok I've uninstalled magisk with the latest uninstaller. But now when booting up, the phone is stuck on the "please lock bootloader page" and is not proceeding further. Given that I can still use TWRP, should I just follow the LOS 16 pie instructions and install the bootstack, modem, Gapps and the zip file?
I could root the phone by flashing magisk once I'm done flashing these things right?

Yeah, go ahead and flash Los 16.
Flash your bootstack and modem, and reboot to recovery from TWRP. The TWRP version will have changed. You need to flash latest TWRP image again, use Orden 3.2.3-0 TWRP from LOS 15/16 thread. After that, reboot to recovery and continue with the rest of the steps.
You can flash Magisk whenever you'd like, hell you could even flash it 1 year after running Los 16 haha.

You are my saviour. You've helped me so much. But I'm scared of bricking so please don't be annoyed by me when I ask for confirmation.
So basically I installed the vendor partition using party from @Oki like the LOS 16 guide required.
But now as to the things you told me to do.
First I'll install the universal bootstack for LOS and my model specific modem from https://androidfilehost.com/?w=files&flid=270519
Once both are flashed my TWRP version will have changed so I will flash the latest version of TWRP again using fastboot
Then I'll go on ahead and install LOS 16 and GApps
THANK YOU SO MUCH IN ADVANCE.

YAAAAAAAAAYYYY!!!
I just installed LOS 16 and everything seems to be working fine.
But the thing is I downloaded and flashed magisk through TWRP, and the installation went fine. When I booted into LOS even the magisk manager was installed.
But when I installed the root verification app from playstore, it said that the device was not rooted. Any advice? Other than that it feels so good to finally be on a custom ROM. Thanks for your help.
I wish you success and happiness from the bottom of my heart.

Problems with installing LineageOS 17.1

Good morrning everyone!
i am a little bit helpless with my plan to flash LineageOS 17.1 onto my OP 6T. I started from LineageOS 16, which was rooted with Magisk.
With my first attempt I followed the instructions from https://wiki.lineageos.org/devices/fajita/install. I used the latest files from 20200903 of LineageOS. But after flashing temporarily the recovery, I ended up with a stuck in oem-unlock-screen. To fix it i used the MSMtool 4.0.59.
I flashed only boot and not boot_a or boot_b. So I tried it with that now. But I only got the same results. I was unable to boot into recovery. So again MSM Tool and unlocking the bootloader.
Then I tried to install it via TWRP. OOS 9.0.13:
1. booted into fastboot mode
2. booted TWRP 3.3.1.0
3. Wiped Data and rebooted into fastboot mode
4. booted again TWRP 3.3.1.0
5. installed LineageOS lineage-17.1-20200903-nightly-fajita-signed.zip
6. installed TWRP 3.4.0
7. rebooted into recovery
8. repeated 5. and 6.
9. rebooted into recovery
10. installed open gapps-nano
11. installed Magisk 20.4
12. rebooted the system
Result: Qualcomm CrashDump Mode......
I do not understand what I did wrong. In June I installed Lineage OS on another OP 6T and it worked fine with flashing the recovery to boot_a. But I do not know which OOS was installed. No I am trying it since hours and only end up in the above mentioned results.
What do I have to do? Thanks for your help in advance!

My LOS Install Guide
- Don't use TWRP 3.4.x. Use 3.3.1-32 (The latest 3.3.1 version.) 3.4.x will give you issues.

I also just noticed you are trying to use a very old version of OOS (which also means old firmware). Why are you using 9.0.13? Perhaps this could be your issue.
I need to update my guide, but 10.3.5, and the latest weekly 9-3 work fine. One warning, I never did get the 10.3.5 fastboot ROM to work on either of my 6Ts. The 10.3.4 Fastboot ROM works fine, then I had to update to 10.3.5 using TWRP.
I asked if anyone else had problems with the 10.3.5 fastboot ROM in the fastboot thread but didnt get any replies...
I started at first wit OOS 9 because of the latest (?) msm tool. I regocnized later, that it is crucial to update OOS to Android 10 what I did after I posted my question. I installed OOS 10.3.5 from oneplus.com via TWRP.
So all I had to do yesterday was to reinstall TWRP 3.3.1-32.
Your guide for installing LineageOS was by far the best I got. All the little explenations were the things I needed to understand, why the steps had to be done. So again thank you for your help and your guide which is really really good.

Also if you like themed TWRP @acuicultor and @ morphine1e1 have a really nice creation for OP6/6t here: https://forum.xda-developers.com/on...covery-theme-blacked-twrp-acuicultor-t3847752
It's latest twrp but I've been using it for months without any issues and I flash much more than a regular user. Installed LOS twice and all good.
或许你应该先升级到安卓10 再去安装lineage os 17

Samsung fastboot confirmed

I have successfully used fastboot to flash TWRP to my Tab S5e. Android 10 moved fastboot to userspace as fastbootd and if you have the right recovery it works on Samsung. I used Lineage recovery from local 17.1 build on my machine. Got curious about fastboot options in recovery and it works. Check this to better understand https://source.android.com/devices/bootloader/fastbootd Yep that is source.android link no joke. Device codename can be seen in screenshots.
Does this mean we can flash TWRP Recovery and then just root it with flashing Magisk via TWRP recovery? Thanks.

Sort of, if you already have LineageOS or another custom ROM that supports it. Stock samsung does not support fastbootd. AOSP based roms should have it as of android 10. It also requires the recovery be compatable. Lineage recovery provides access current TWRP did not. It is explained here https://source.android.com/devices/bootloader/fastbootd . It's a neat trick but not for initial root or custom recovery, still same as always you have to have it before you can get it. It does not replace Odin and the same steps are required as always to root or install twrp on stock Samsung. But once you have access it works to flash magisk_patched.img on LOS which can be good since Lineage 17.1 does not have official su support.
