Holding down the power button, the power button + volume up, and the power button + both volume buttons does not do anything. What does “Qualcomm CDMA Technologies MSM QUSB_BULK_CID:0402_SN:B48453B9” mean?
I followed the guide using a prebuilt postmarketOS image (v25.12 w/ Phosh). I ran fastboot erase dtbo, fastboot flash boot (.img file), fastboot flash userdata (another .img file), and finally fastboot reboot. I saw a few Tux penguins in the corner and saw the postmarketOS logo. Then, the display turned off. After that, I rebooted in fastboot mode and retried the fastboot flash step and did fastboot reboot. Now my device seems to be unresponsive and appears as “Qualcomm CDMA Technologies MSM QUSB_BULK_CID:0402_SN:B48453B9” (in Android, it was seen as “OnePlus 6”, while in fastboot mode, it was seen as “Google Android device”)
Has anyone ran into this issue and know how to fix this?
edit: I did unlock the bootloader using “fastboot oem unlock” before flashing anything
I think you need the MSM Download Tool to reflash your phone to stock and start over
There’s an unofficial reimplementation of QC firehose/sahara, it works correctly on my OnePlus 6T.
That seems to be Windows exclusive, and Wine doesn’t work with it
if you need to use any of qualcomm tools, you should install win7 or 10 in a vm. these are mostly leaked internal tools and there’s usually no foss equivalent sadly
Yeah, a quick option would be downloading one of those Windows VM images Microsoft provides. They’ve got them for testing their browser, just uss those.
Ok I will try to set that up later
