The problem is that fastboot is kicking you out of fastboot within a second
...ok, nice 😵💫 ...is this the "normal" behavior on this device??? ...there has to be a "cheat code" to access fastboot ...fastboot has to be accessible, it's the "initial loader", sometimes I call it the "Hypervisor" 😅 ...you say, it pops up and suddenly restarts the device ...I think, there is some sequence, bit code or something it is waiting for, just for some milliseconds ...there are routers by AVM using some similar behavior for accessing the bootloader (Adam, I think), where you have to trigger an FTP connection before powering on the router ...did anyone try dumping the USB port with a logic analyzer during this short fastboot period? ...maybe some kind of handshake is needed 😳

No it's only normal on A12 not on A11.

So they broke something

The thing is regardless if you use key combo or adb reboot bootloader it just kicks you out from fastboot.

It can be accessed for one second lol

Can confirm I also can't get into fastboot anymore. The button combinations or adb reboot bootloader results in a one second fastboot then boots into system
You don't need fastboot to boot gsi.

Find a compatible gsi for your device. Load it and reboot when prompted. The custom rom/gsi should load. Then open a terminal on your windows pc in the adb folder and open a adb she'll then confirm your device is detected. :] Adb devices

ADB works fine and the device connects without a problem. It's just fastboot that won't work. Rolling back also doesn't work.

Download and install dsuloader.


Download this GSI


Follow this guide for help with this DSU mission.




Note:
GSI are kinda of tricky some of them will work some will just bootloop.

If one doesn't work. Try a an other one.

I'm not really sure what your trying to achieve. But if you manage to boot a gsi you can pull your entire partition using adb commands and then push the partition to your windows/Mac/linux machine

I'm trying to unlock my bootloader so I can flash a gsi and not use dsu at its not a full "rom". I can't get a dsu to install either always results in an error

...sorry for disturbing you, but I think we have to clear some essentials ...you know, DSU has particularly nothing to do with GSI ...the "Dynamic System Update" is just used to insert a "Generic System Image" in this case and is not what the "final" result will be ...it's just a temporary launch of a system ...just like a Linux on an USB Stick thing ...but you will be able to access the "real" boot image and dump it to local storage ...but at very first you have to unlock your bootloader ...and as we learned there is some kind of fastboot bug rendering it unaccessible ...a devil's circle 😅 ...just wait for fastboot getting fixed and take the "easy" way

...best regards

    Team Win Recovery Project 3.x, or TWRP 3.x for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.



    Code:
    #include <std_disclaimer.h>
    
    /*
    
    *
    
    * We are not responsible for bricked devices, dead SD cards,
    
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    
    * do some research if you have any concerns about features included in this ROM
    
    * before flashing it! YOU are choosing to make these modifications, and if
    
    * you point the finger at us for messing up your device, we will laugh at you.
    
    *

    What works:

    Not fully tested main features work

    This is why you need to get a gsi working on your device.it might fix the fastboot
    No GSI will not help at all. Infact they broke bootloader somehow

    Just sold my Nord ce 2, as for me not being able to access the bootloader ruined the phone. This was my first and only OnePlus. Real shame as the hardware was great.
