Device: an ASUS X00PD, computer: Ubuntu 23.10 with ADB and fastboot installed.
I cannot even bootload the device: On the device I press power + volume up buttons to enter bootloader mode but the device stays there half a second. The device then turns itself down, restarts itself and cycles like that till the battery dies.
I don’t want to go back to stock software, Id install anything that works for this particular device.
I think your best bet is looking up the button combo to boot the device into fastboot mode and quickly booting a recovery image (I think power + volume up). Try running
fastboot boot your-recovery-image.img
while it’s still on (this should boot TWRP/some other recovery images without flashing anything and bricking your Linux install) and explore further steps.If fastboot doesn’t work, it’s possible the bootloader is screwed. If that’s the case, you may be able to get the phone into emergency download mode and recover through that, but that’s not as well documented as using adb or fastboot. Getting into this mode may involve shorting two pins on the phone’s motherboard or getting a special EDL cable.
Support for your phone seems to have died out a few years ago: https://xdaforums.com/f/asus-zenfone-max-m1-roms-kernels-recoveries-o.9971/
I don’t think there are any newer ROMs for it than the builds that are available in the archives. Best place you can ask is probably the xda forums.
