Hi, I was hoping someone could upload the fastboot files, or even just the boot.img file for the international 10.5.11 rom as I am stuck in fastboot after taking the OTA and flashing Magisk to the other slot.
I'm pretty sure its because I had xXx rom module enabled.
Any help would be appreciated.

I have OS X and in this system is not easy to flash firmwares with tools.
before OP8 i had xiaomi mi9t pro so to flash fastboot rom it was not possible as there are no tools which works with OSX, so solution was to edit flash_all.bat
and in fron of each fastboot to put ./
as in osx command terminal fastboot doesnt do nothing. command has to be as ./fastboot
so then in that extract fastboot rom folder we put inside adb and fastboot from platform-tools folder
we open terminal and make cd to that extraxted folder of fasboot rom, then we copy flash all .bat to terminal, and flashing starts.

i didnt try this way on op8 but i successful edited flash_all.bat file for fastboot flashing in os x

Why after flash it, it boot up to Qualcomm crashdump mode and how to fix?
Did you get lucky with this mate? I've got the same issue and it looks like that my OP8P (Unbranded, Europe) is not jumping into the fastbootd mode but just tries to start up normally which brings me to Qualcomm crashdump mode.

I think it really stumbles here:
<...>
Finished. Total time: 0.047s
Rebooting into fastboot OKAY [ 0.002s]
< waiting for any device >
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.

Sending 'abl' (1996 KB) OKAY [ 0.057s]
Writing 'abl' FAILED (remote: 'Flashing is not allowed for Critical Partitions')
fastboot: error: Command failed
<...>

Anyone has overcome it please?

Please help me to unbrick my miserable OP8P...

You do realize that these are for the 8 and not the 8 pro right? Also you can put your phone into fastboot mode without a command. When I tried to use these for the first time I kept getting errors and it would not flash properly but I found a post where the user had to use large address aware to patch all of the exe's in the folder to work properly on a 64bit pc, which is pretty ridiculous that we even have to do that but it worked.

Just realised that. At some point I was reading the correct thread but somehow then posted this message into the wrong one. However the OxygenOS I used still was for OP8P. I will move my ass onto here https://forum.xda-developers.com/oneplus-8-pro/how-to/rom-stock-fastboot-roms-oneplus-8-pro-t4083997

apologies for the confusion and thank you for your reply, I will consider your solution anyway.

I ended up using bootcamp to install win 10 to mess with my phone since everything is written for widows anyway.

Never mind I fixed it by downloading ota and going to system updates in settings because fastboot won't flash to modem right
I did the same thing with Android 11 (OnePlus8Oxygen_15.O.30_OTA_0300_all_2010031624.zip) thinking I could simply reinstall TWRP and flash Magisk to regain root. Serious mistake. Attempts to boot into TWRP after flashing results in Qualcomm Crashdump errors. I can't even boot into the stock recovery without Crashdump. Also, using a program called payload_dumper I extracted boot.img and other img files from payload.bin. I patched boot.img with Magisk and flashed. It didn't work.

I've been rooting phones forever and I see no way to root this thing. Does anyone have any ideas or any way to help me out??

Questions

Mauronofrio: First of all congrats and many thanks for the awesome job you're doing.

I'm not too clear on what you mean by “fastboot -w” (sans quotes). You said this is to format data. Will it delete anything? Also, should you issue this command before or after applying the batch file?

I imagine you're a busy man, but whenever you get around to it please put out a zip with all those img files for "OnePlus8Oxygen_15.O.30_OTA_0300_all_2010031624_c5e68b42b3325". This just came out today (Oct 24) and, as you know, it cannot be flashed.

Before this Project Treble garbage if we bricked the phone we could easily flash the OxygenOS Rom. Sadly that's not possible any more. Do you believe this is a viable alternative in case disaster strikes? I still have a working copy of an old version just in case, hopefully it'll still be flashable.

Thanks,
