What did you do to try to patch it? Why are you in adb? Does fastboot work?

Patched the boot.img using magisk and then flashed it. After patching, it totally cant boot and can only boot to bootloader.
tried alot of version of MSMtool and it will always fail with param preload error...
Then tried manually recover via extracting the payload using python then using adbtools to wipe and flash but it will also fail because some img files are unable to flash over to the phone...

Any other solutions?

i am able to flash the stock boot.img to the phone but some critical img files will come out with
FAILED (remote: 'Flashing is not allowed for Critical Partitions.
')
fastboot: error: Command failed

You need to be in fastbootd,
Code:
fastboot reboot fastbootd
Nope not working too...

    To be honest, I would download the rom and boot with the recovery image instead, I'll upload the image collection...

    Will post a link here once it's up.

    Actually, just noticed there isn't a recovery image, so boot to the default boot.img using fastboot, then see if the storage shows on your computer, copy the latest default rom over to the main storage folder then then go into Settings > System > System Updates and use the cog to do a local update using the rom zip.

    That should re-install everything back to default, you might get lucky and still have all your data

    My collection is for the Europe build FYI:


    MD5 : 00227014483b4913a2624fac6f492434

    So you would reboot the phone into fastboot mode by holding vol up during boot
    Once you are in fastboot mode connect the phone to your computer
    Test that the computer can see it properly using fastboot devices
    You should see a number returned, if so then your computer is recognising the phone, if you don't then try installing the latest drivers from here
    If fastboot can see the device properly then copy the default boot.img to the same folder as your fastboot.exe and type the following :

    fastboot boot boot.img

    You should see a message saying it's transferring it to the phone, then it should boot the phone using it, it's slower than a normal boot but, if everything else on the phone is ok, then you should see it booted and it should accept your lock method
    Once you get into the phone using that boot.img, try connecting the phone to your computer and see if it's recognised, if it is then copy over the latest stock rom to your main storage folder, then go to Settings > System > System Updates and use the cog to do a local update using the rom zip
    I'm guessing it should let you because it will see a difference between your boot image and the one from the rom.

    Turn it off and try charging it

    Also "fastboot reboot fastboot" isn't a valid command, there is an adb command "adb reboot bootloader" but that can only be run from within your rom from when you are in recovery with the phone connected

    See here :


    #To reboot your device
    fastboot reboot

    #To reboot your device to fastboot mode
    fastboot reboot-bootloader

    Wtf are you talking about. fastboot reboot fastboot is literally the only way to get into fastbootd if you can't get to recovery or boot normally.

    Regarding battery, that I'm not sure, hopefully someone can help
