Help wanted: Oneplus 6 now in fastboot-loop

Hello everybody,
Nice to find more people here trying to keep their privacy!
Although I’ve been spending already 2 weeks, 5231million hours and 3 minutes on trying to get /e/ installed on my specially for this aim bought Oneplus 6, I consider myself as a complete newb, a noob, a dummy and a nono. It feels like being “flashed” into a new galaxy of phone-hacking-pirates where everybody speaks a language I don’t understand.
But it feels good, this is the way to go.
I needed all the How-to’s on the internet to get this far: the phone got stuck in a fastboot-loop: can’t even be powered off, can’t get recovery on,
etcetera. So I managed to get to this part of the Howto where it went wrong, I guess,
** Sideload the /e/ .zip package:*
** On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.*
** On the host machine, sideload the package using:*

```

  • adb sideload filename.zip*
    ```

I don’t remember at what step exactly I ended in this fastboot-loop, I’m sorry. I guess I was too excited seeing things happening in the right direction.
So now I think this is what they mean with “bricked”?
Spending another few hours on finding a way out, even trying to understand some french and german workarounds I found only a solution for Window-pc’s, but I have linux Ubuntu 18.04.3. so I finally thought “let’s ask for some help!”

HELLLP

Some info I saved for “you never know”, maybe somebody finds something:

Sorry, but your post is to long for me for reading on mobile phone. So it could be that you have tried my solution. But if not, try this:

Boot in twrp
Wipe system, data, cache, davlik
Format data
Reboot to recovery again
Tranfer eOS.zip via file explorer or adb push to your device
Flash eOS once more via twrp
Reboot system

Messages about recovery and cache partitions are not expected.
Maybe something happened with unlocking ?

Thanks for the replies,
but,
I can’t boot in twrp

@smu44:
not sure what you mean with “Messages about recovery and cache partitions are not expected”
but the device state = unlocked

Please try the following:

4.Once the device is in fastboot mode, verify your PC finds it by typing:

fastboot devices

5.Temporarily flash a recovery on your device by typing:

fastboot flash boot twrp-3.3.1-2-enchilada.img

6.Manually reboot into recovery mode

Try also to follow the steps and read the support discussion at the offical TWRP OnePlus 6 Thread in the XDA-Developers-Forum:


Good luck! :smile_cat:

This can’t work. I think the docu is wrong.
For flashing twrp the command is:
fastboot flash twrp-3.3.1-2-enchilada.img

And for temporary boot twrp the command is:
fadtboot boot twrp-3.3.1-2-enchilada.img

I have had just read the same problem in community group

terminal output:

l@l-Latitude-E6500:~/Bureaublad/platform-tools$ fastboot flash twrp-3.3.1-2-enchilada.img

Maybe this is also important:
As soon as the phone (turned OFF) is connected to pc it starts automaticly fastboot

Sorry, my command was also wrong :frowning:
fastboot flash recovery twrp-3.3.1-2-enchilada.img

The ‘recovery’ was missing, that’s the reason of the error message. Sorry

Thanks a lot for helping, realy appreciate your help!

Oh, it’s a a/b device. That’s special. I can search tommorow for the best way.

Thank you @harvey186 I’m glad you said it. Can you please make sure that this gets into the /e/ documentation is changed. Your voice will be heard at the appropriate place.

By the way: The same command can be found in the LineageOS How-to-Install.

This device seems to have a special installation procedure, as described here : https://twrp.me/oneplus/oneplus6.html
In short, TWRP flash should be done in TWRP himself, having the image somewhere in phone’s storage.
There is a screenshot in the XDA support thread.

Here you will find a good HowTo for A/B devices (from point 9 on).
Could you please try that way ?

from point 9 on I get a different outcome at the first step already, something with “failed” :frowning:

could you pls try an older TWRP version ? I have read somewhere, that there is an issue after TWRP 3.2.x.x

I search for the older twrp-versions, but if they don’t have “enchilada” in the name I think they’re not the right-ones, correct?

have a look here https://eu.dl.twrp.me/enchilada/

That’s where twrp-3.2.1-0-enchilada.img is the oldest, right?
