    Thanks for your advice!
    I managed to fix it by using different img and zip files in the downloads from the guide I followed.
    TWRP is staying now as it should do, now I'm just waiting patiently for some Android Pie supported Magisk Modules! :D

    That would be amazing! Although do you not think that in a way Magisk is sort of competing with Xposed with the modules aspect? The Dev for Xposed is fairly quiet when it comes to ETA's etc so I'm not so sure how soon we'd expect to see an Android Pie release.

    I bricked my phone.

    i have rooted my phone with magisk manager and i don't have any custom recovery installed but my phone was working fine since last 10 days(i flashed it on 1st November). I even did a system update to 9.0.5 and rooted it again and all went fine until today. when i was rebooting my phone i decided to press the power key when the unlocked bootloader warning showed up and since then it isn't responding to anything, I tried holding the power button for 15 seconds and power+ volume down, power+ volume up, power+ both volume buttons but its not responding at all.

    My battery was just 17% when i decided to reboot and it has been 3-4 hrs, i am still waiting my phone battery to drain out so that i could somehow access fastboot but i think it will work fine unless i press the power button again during the warning screen.

    So my advice to everyone is to not press power button during the warning message or you might also end up in the same situation. And if you have done it in the past and your phone still works please let me know.

    Edit: i have done some rough calculations and it shows that my phone will take about 40 hrs to discharge completely and the real issue i am worried about is that there will be a BURN-IN on my display if its going take so long

    please someone help me regarding this issue and ask your friends if they can help. I dont want burn-in marks on a my phone so early.

    I tried creating a thread but it shows i dont have the permissions.

    I rooted my phone today and it worked well then I installed a magisk module called "Oxy mod" and and later uninstalled it and rebooted my oneplus 6T. It is stuck in bootanimation. I accessed device storage using pc and all folders names are changed. What should i do know?

    that means all your files are encrypted and pc can't read your device contents.

    What you need to do is download the stock files and install everything via fastboot.

    I am following this guide here to root oneplus 6t (european variant), 9.0.5 Android:


    bootloader is unlocked and I can see there is a positive connection between phone and PC by checking the output on adb devices and fastboot devices. both work as intended.

    the problem is that when I try to adb sideload, it says that I need version 1.0.32. so this means I cannot flash the custom recovery.

    any tips? been looking online for quite some time now and cannot figure out what to do anymore. where can I find this 1.0.32 adb version?

    I am a long time user on nexus 5 and just bought this phone, want to root it aswell. (note: this does not mean I have high level of knowledge on these types of hacks, just wanted to have this clear.)

    This happened to me before and I discovered that I had to disconnect the USB cable from the phone before forcibly rebooting.

    removing the cable didn't work for me. I visited the service centre and they flashed the stock ROM.

    Hey how did you manage to take nandroid backup? I'm using blu spark twrp v9.86 and it gives error.

    Can not create '/data/media/0 TWRP' folder (Required key not available). Failed to make backup folder.

    I think it's because my phone is encrypted. Can you tell how to take a nandroid backup, i have tried taking backup with and without pattern on the phone.
