    Hello. I recently updated my Oneplus 6 to OxygenOS 11 by the Oxygen Updater. My device is Rooted so i lost my root. But when I'm trying to root again my phone with TWRP by "fastboot boot twrp-3.5.2-enchilada.img", it show a beautiful "Qualcomm Crashdump Mode" page with the content:
    "Attemped to kill init! exitcode=0x0000000b, complete_and_exit"
    My device is actually alive and not bricked, and i want to keep my datas without a factory reset.

    My goal is to start TWRP by "fastboot boot".
    After some hours of searching, i found somes issues, but outdated (2 years).
    We need to create a new solution in 2021, to help everyone who's lost like me.

    I already found some pieces of a way to find an issue:
    I tried to press Vol Up + Power on the Qualcomm error page and it did a black screen but i don't know if i did that correctly.
    I don't want to lost my datas by the MSM tool, flash stock ROM or something like this.
    I don't know if there is a "bypass" method to start TWRP properly.
    I heard something about the Emergency Mode (EDL), but i think it's for flashing Stock ROM.

    Please help me and everyone.
    Thank you so much

    Hi Enoal.

    I have exactly the same problem. I too have done this way dozens of times after installing an update. Now suddenly this problem. I'm going to try something else this week, but if anyone has a solution I'd love to hear it.

    My way that always worked.
    Open a powershell in ADB.
    Install there in temporary twrp via fastboot and run.
    In temporary twrp install the permanent twrp.
    Then install in permanent twrp magisk.

    Now after fastboot boot twrp.img comes the fastboot logo and then the error attempted to kill init

    Hello !
    Oof thank you I am not alone with that problem. You have exactly the same problem. This weekend I'll try to backup my datas and use the MSM tool to repair the Qualcomm system. It will to a wipe data and I think "delete" the Qualcomm error problem.

    On this link, I already tried the first method and now I'll try to make the second.
    From a Google search "Qualcomm Crashdump mode fix" we can find so much website this theses methods.

    To solve this problem we need a HERO !!!

    Hi. I have news. I have an idea. I searched and we are doing update and after root again the device. But most of people do the update, don't restart, root TWRP and Magisk on the second slot. And when restart they have the update and root.
    Like that we can do that I think. So I'll try that steps by steps :
    1 - Save data (for a potential wipe data)
    2 - downgrade the version, to remove the Qualcomm Crashdump mode error and root again
    3 - root again the device
    4 - flash the updated, flash TWRP (if you want) and Magisk on the second slot
    5 - Restart and enjoy

    I'll try that and I will let you know if it's working

    "That makes SafetyNet pass? I did the classic routine:
    - Install full zip (OnePlus6TOxygen_34.J.60) via 'Local upgrade' - no rebooting
    - Flash TWRP installer (I had 3.4.0-11) via Magisk - no rebooting
    - Flash Magisk via Magisk to other slot
    - Reboot! All done."

    Did you the Android 11 upgrade with update in Oxygen, then flash TWRP and Magisk without reboot. Then reboot?

    And how did you flash twrp and magisk without reboot? With magisk?
    I try tonight.

    Yes this is steps of how I did that:
    - Download a OxygenOS of Android 10 (i did 10.3.11)
    - Download TWRP and Magisk
    - Save your data (wipe data)
    - Open settings --> Updater --> Local Update
    - Put your OOS 10 in your main storage
    - So click on your version in Local Update
    - Installing....Reboot and say bye... Wiping data
    - Start on Android 10, so put TWRP zip and img and Magisk to root your device. Fastboot steps to root i think you know how 😄
    - Restart your rooted device on Android 10, and Download the Android 11 update and same steps install it in Local Update
    - Do not reboot, from magisk, go to modules, Install From Storage, and flash the TWRP zip, go to main menu of Magisk and click on Install, and choose OTA Method, after that Reboot
    - And you're rebooting on Android 11 ROOTED
    Ask me if you have any questions

    Nice, Congratulations!
    So now if you're not in OOS, you need probably to do the update. For me, i just did the Android 10-11 Upgrade directly by OOS so I don't have updates to do.
    Now if we are on Android 11 and an upgrade to do, we need to do this steps :
    - Save datas (if you want, no wipe data)
    - Download and install OOS update, do not reboot
    - In Magisk manager, Modules, Install from Storage, TWRP zip
    - In Magisk again, Magisk Install, OTA Method, and reboot
    - Starting on Android 11 update OOS with Root TWRP and Magisk !!

    To answer your question, yes you need to do this steps.
    Ask me if you have other questions 😄
