Question fastbootd mode not possible

[dlareghoe]

Hi there,

I am trying, because of bricked device, to get in fastbootd mode.
I'm using the command 'fastboot reboot fastboot', which ist the correct syntax, after some instructions.
Unfortunately, the only result is: "fastboot: usage: unknown reboot target fastboot"
Is there any idea, how to get into fastbootd mode?

Thank you
g.

No chance to get into fastboot mode with Power Buttom, Volume up and Volume down?
If yet, fastboot boot boot.img sometimes helps. At least it did it for me...

There's are definitely ways to break fastbootd. Sounds like op doesn't have issues getting to bootloader. MSM is the easiest way to fix it and that's the way I'd go if you didn't mess with your device too much. You can also flash your backup super.img from bl and hope for the best.

MSM tool says Unsupported Target EU

What is your device's model number, and which msm did you try?

You need the correct msm tool

By using these tools, you accept full responsibility for your actions. Your warranty is void should you run any of these utilities without OnePlus support present. I am not responsible for bricks, fires, nuclear war, etc. If you modified any...

On my last op device 7tpro. The only way to get to fastboot d was with phone on and use adb reboot fastboot. The fastboot reboot fastboot never worked for me and I assume it's the same on this device. I would go for the msm

Sounds like your platform tools are out of date

Nope they were latest from sdk when I tried on op7tpro

That was my mistake.
Now working perfect again.
Just had to find a Windows Machine, MSMtool don't likes VMs

I noticed you said backup super.img, which is related to an issue I have currently, because slot B on my phone is missing system_ext, product, odm, and vendor, the partitions located in super. so my question is how (in fastbootd) would I flash my backup super.img directly to slot B? and is this even possible? slot A works fine and my phone boots, but slot B is f'd up and I can't flash a rom (stock oos to stock oos) because it reports slot B is missing those partitions, essentially the ones located in super, and this wouldn't be an issue but fastbootd will fail when attempting to flash those partitions individually to slot B (file missing error)

 

[craznazn]

Super contains both slot a and b

Super contains both slot a and b

fml. then I really do not know what my issue is. how could I be missing the partitions in super yet my phone boots totally fine on slot A. when attempting to flash oos twrp reports system_ext, odm, and product are missing on slot B and I can't flash the update. if super is both slots I am stumped on how this is happening.

You can try this in fastboot (not fastbootd), but, I never tested only modifying 1 partition so be prepared for the worst:

fastboot delete-logical-partition system_b
fastboot delete-logical-partition system_ext_b
fastboot delete-logical-partition product_b
fastboot delete-logical-partition vendor_b
fastboot create-logical-partition system_b 100000
fastboot create-logical-partition system_ext_b 100000
fastboot create-logical-partition product_b 100000
fastboot create-logical-partition vendor_b 100000

ok thanks bro even if it doesn't work. I'll have to add in the odm partition to those commands too, but I see what you did and how to do it.

 

[craznazn]

Sure, but just do local upgrade from slot A
