Not able to power off phone no matter what

[zeuses23]

Hi all!

Long story short, basically my OnePlus Nord gen 1 is bricked (no recovery, no ROM). In the current state all it is able to do is boot into the bootloader. The bootloader gives several 'options' such as "boot to recovery", and more importantly, "power off". But no matter what option I choose, the phone ends up rebooting back into the bootloader.

I've tried to follow guides on XDA instructing how to unbrick the device, to no avail. The main guide I'm trying to follow is the MSMdownloadTool guide, but that requires me to power off the device to enter EDL mode (which it isn't doing).

The device seems to be stuck in fast boot mode, but isn't using fastbootd so I can't make changes to critical partitions. Since it is stuck in fastboot mode, adb commands don't work. I've tried reflashing the recovery, but that didn't work. I've tried clearing cache but there I'm running into 'cannot generate userdata' (fastboot erase cache spat out "failed; check device logs").

As for hardware buttons, using volume down + volume up or even volume down+power does nothing, volume up + power button or holding all 3 just restarts the bootloader, and holding just the power button does nothing except for repeatedly select "start"(causing it to reboot back into bootloader).

I feel if I can just get it into EDL mode somehow, everything else will fall into place. Any help at all will be much appreciated

You might be able to enter EDL mode by opening the device and using a jumper to touch certain contact points on the board and force it into EDL mode. I don't know your hardware so I don't know which points to tell you to use the jumper on, you'll have to do some research to figure that out based on the specific device you have.

unrelated. you can flash super.img from fastboot. flashing critical partitions maybe needs unlocking.

Hello if this can help my device was dead , not even fastboot or recovery was working and was bootlooping. What i did is installing MTK authentication bypass ( i dont know if your phone is mtk cpu ) , then i instaled libUsb driver that came packed with that tool.
Then you open libusb driver installer, and when you keep pressed power + vol down to enter Brom mode, it should detect a com port that disappear in few seconds, what u need to do is click install driver as soon you see that com port appear.
Now you open the bypass tool with phone disconnected, click on bypass, and then connect the cable, now enter Brom mode with power + vol down, and the tool will say Success.
Now your phone is ready to use with any flash tool ,like sptools.
Hope this helps.

Hey, thanks for the suggestion! But i would very much prefer not to open up my device. I've also heard that there is an EDL cable, but I don't know if that'll work either. Lets see

Thanks for your reply! A silly question, but what does super.img do? I tried flashing the critical partitions after running "fastboot oem unlock_critical", but that still gave me the error.

Hey innergat, unfortunately I believe my phone has a qualcomm chipset, so this probably won't work

Dynamic partitions are logical partitions hosted in physical super partition. logical partitions can only be accessed from fastbootd, physical partitions from fastboot.

To enter EDL mode try selecting power off and then immediately hold volume up + volume down.
