Hello. I recently got a vontar-dq08 working with armbian. I used someone's build for a x88pro, so I replaced the dtb with the one that came on my board. After editing the ArmbianEnv.txt and resetting, it did not boot. Idk if it's a typo on my end or the tree not working, but to make it boot I would just have to change ArmbianEnv.txt, but taking the sdcard out and plugging it in my computer I can't find the file in /boot
How can I revert the ArmbianEnv.txt when my machine doesn't boot?
