hi i run to an issue after updating my phone and i no longer can send the patched boot.img to my phone
all drivers are installed
i download the original firmware from oneplus website and use the payload dummer to got the boot.img
i use magisk to patch it as always

and here is what i got

PS C:\Users\Angel\Desktop\platform-tools> adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
21840241 device

PS C:\Users\Angel\Desktop\platform-tools> adb reboot bootloader
PS C:\Users\Angel\Desktop\platform-tools> fastboot.exe devices
21840241 fastboot
PS C:\Users\Angel\Desktop\platform-tools> fastboot flash boot magisk_patched.img
error: cannot load 'magisk_patched.img'
PS C:\Users\Angel\Desktop\platform-tools> fastboot flash boot_a magisk_patched.img
error: cannot load 'magisk_patched.img'
PS C:\Users\Angel\Desktop\platform-tools> fastboot flash boot_b magisk_patched.img
error: cannot load 'magisk_patched.img'
PS C:\Users\Angel\Desktop\platform-tools>


non of the last 3 commands works
i have magisk_patched.img inside the platform folder


any idea how to fix it???

You have to have the patched file inside platform tools folder on your laptop
