    So I'm probably one of the kind who manage to brick my brand new OnePlus 7 Pro in a first day trying to install twrp, magisk. First I had problems with TWRP seen files on a phone (screenshot #1)

    after numerous attempts of flushing TWRP, mounting storage etc I decided to start all over and lock the boot loader via "All Toll In One". Now I can't boot into bootloader or recovery at all by holding power and volume keys, and all I see now is this message (screenshot #2)

    Now I don't know what to do...

    Oof you locked the bootloader before the phone was completely back to stock? That's rough.

    If that's the case there's not going to be anything you can do on your own to recover it until someone manages to get their hands on the unbrick tool and share it with the public.

    I'd suggest you contact OP support and start a remote session with one of their techs to reflash your device back to stock.

    Well that's unusual, normally they would bump you up to a level 2 tech who would use the unbrick tool to remotely reflash your device. I wonder if they don't want to risk leaking it so people won't use it to bypass the locks on the T-Mobile version like they did for the 6T. I suppose it wouldn't hurt to try requesting a remote session and if they say no then at least we'll have a definitive answer.

    I got it, all I had to do is holding volume up, down and power key at the same time to get to bootloader.

    Hey man, what did you do after you got to the bootloader? I'm facing the exact same issue. I de-selected "enable oem unlocking" in settings, then did "fastboot oem lock" and then the same screen with the "your device is corrupt" message is showing up and I can't do anything except get to the bootloader. I tried doing "fastboot oem unlock" but I'm getting an error message, I also tried to do "fastboot erase userdata" erase cache and the "flash-all" from the batch file in the stock GM21AA ROM file but everything I try fails and I can't do anything except be stuck on the "your device is corrupt" screen or the bootloader. Help please.

    You even don't go to Qualcom Crash Mode ?
    The tech told you to only go fastboot mode (power - power + power) ?? That's strange ?

    I suggest trying what I did
    1.boot into TWRP
    --> Wipe All data, Yes,
    Go to the other slot,
    --> Wipe all data , Yes,
    then wipe, Internal storage, apps, cache, data

    2.boot into bootloader
    try to download this file=
    " 9.5.3-GM21AA-OnePlus7ProOxygen_21.O.07_OTA_007_all_1905120542_aa37bad-FASTBOOT"
    found in the downloads section of this thread
    https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424

    after you connect in fastboot, try to perform the flash-all.bat
    after that's done, try to boot once more into recovery
    my device erased some extra things, which made me able to boot.

    So my phone is really BRICKED and i need to flash stock signed file using MSMDownloadTool and the OP7 Pro Dump.

    I find dump for all one plus except for OP7 Pro which is too new.

    Please can someone provide me OP7Pro Dump flashable in Qualcom Crash Mode or something like that ?
    Oneplus can share me the file and the instruction ? I can do it my self.

    They don't want to get back the device to fix it i hope .... :(
