    I've been having issues with the oxygen os ROM bassed on android 10 and tried to restore back to android 9. I tried the recovery method on the community, but I messed something up because I got a message saying the system was corrupted so I decided to try my method, boot up twrp and flash the android 9 oxygen os rom back on it. unfortunately, that didn't work. unlocking the bootloader was easy enough, but when I tried "fastboot boot twrp-3.3.1-2-enchilada.img" I got the error "remote: unknown command". all the articles said that this was the command to boot twrp without flashing it. I don't know what I'm doing wrong so, at the moment, the phone is a paperweight. can someone tell me what I did wrong?
    BTW, I did use the search function but didn't find my solution. if I missed it, I'm sorry.
    I also want to point out that I tried both a Windows machine and a Linux machine

    TWRP doesn't work with A10 yet. Depending on the severity of the situation, you may need to run the unbrick tool (which your data will be wiped).

    Hi, thanks for your reply. where do i find the unbrick tool? I've googled it and can only find the unbrick tool for the Oneplus 3/t and 5.

    Look for "MSMDownloadTool" on XDA-Developers.

    Just gave it a go, no luck. unfortunately, I think I bricked it. learned a very hard lesson today.

    Update: I missed a step (damn my dyslexia) now my phone is showing signs of life again. thank you for your help.

    Couldn't find it or the tool didn't work out?

    HI, I found the tool and downloaded it. I missed a step. I forgot to put windows in test mode and that fixed it. the phone is now up and running on Android 9 version of oxygen os.
