    my phone started heating up while I was not using it. And it was really slow when I tried to use it. So I tried to restart it and now it is stuck in Qualcomm Crashdump mode. I tried to reset it but it's still stuck in that mode. please help

    DID what @Swejuggalo help you @Xelceus or are you still stuck?
    If you are still stuck, immediately call tech support ASAP, especially if you're cell is not backed up and you don't want to lose EVERYTHING, possibly even the entire OS as well. 😲 WOW!
    Now that's definitely a crazy 🤪 BIG-TIME Glitch

    Hi, a phone call to customer service might work better.

    we don't have OnePlus customer support in my country [e]1f625[/e]. I picked up the phone in India. I'm living in the Maldives...

    This may work to unbrick the phone, there is no guarantee as it may be a hardware fault. But sometimes the info here on XDA may help.

    Ensure you use the tool for your region. Read all the details carefully, you use this at your own risk.

    Have you tried going into fastboot and restarting? If it's a simple software glitch it will fix your issue. If more complex you need to install whatever was causing the issue via the help of your computer.

    Here's an example from the internet. If this doesn't suit you, have a look through Google, there are many helpful videos.

    I had the same issue I got my phone repaired through a repair store near me. The problem is in the hardware not in software.

    I had similar issue but my phone screen was completely unresponsive and didn't show anything. After trying to install Paranoid Android 12 on OnePlus 9 Pro and failing to do so.
    So I reverted to old stock OOS 12 ROM after flashing stock payload on fastboot I made probably a command mistake and got phone hard bricked with what I think was also QUALCOMM CRASHDUMP MODE.
    Because my computer recognized my device in Device Manager on Windows 11 as "QUSB_BULK_CID:(cid code was here)SN:(sn code was here)." The device driver did not pass the windows driver integrity check so I could not use it.
    So Installed Qualcomm drivers and rebooted Windows 11 to recovery mode to turn off driver integrity check on boot.

    So I fixed it by getting the device via qualcomm drivers to communicate with the PC.
    After booting to Windows 11 the OnePlus 9 Pro CPU drivers worked and showed on Device manager as "Qualcomm HS-USB QDLoader 9008" I could use MSMTool to wipe and flash stock ROM on the OnePlus 9 Pro. I failed couple times because MSMTool showed Sahara Error. I once even had to use another laptop to try once more again. But eventually I connected and used this MSM setup to flash the OOS Stock 12 ROM on the device.

    This setup will fix your device. Just click ENUM and START after setting it up.

    It fixed my Hard Bricked device I was happy I could download StagOS ROM with Pixel UI finally.
    But you will lose your data, but if you have auto backups on cloud and Google there are no problems. You can just download all your apps they will save most of your app data and passwords.
