HP Pavilion 15 -- Verification of flashed BIOS image failed bootloop
To preface things, I have an HP Pavilion Laptop, model HP Pavilion - 15-cw100.
I updated my BIOS to the latest version (F.48.Rev.A) through HP's official website. However, once the writing to the BIOS was complete, I got an error saying "Verification of flashed BIOS Image failed". With this, the system went into a boot loop where it would boot to the HP BIOS Recovery and repeat the flashing process only to return the same error message.
I then attempted to recover the BIOS using an external USB, and I attempted to flash F.48.Rev.A with the USB, and I got the same message. Upon analyzing the logfile, I got something that mentioned "Verify of Block 46 Failed". I then repeated the process with versions F.47.Rev A and F.46.Rev.A only to receive the exact same error.
When recovering the BIOS with F.42.Rev.A, however, it successfully recovered the BIOS and displayed "The system BIOS recovery is complete". I let the laptop sit and perform its reboot sequence, and the laptop turned off after a few minutes.
Now, when I turn on the laptop, I see a black screen and the laptop turns off after a few seconds, and this process repeats again in a loop.
Some things I have done to try to fix this:
- I removed the NVMe drive, battery, and reseated the RAM. I'm running the laptop only off of AC Power as of right now.
- I have tried both the Win + B and Win + V Keyboard combos with a USB containing a recovery BIOS as suggested by the HP Troubleshooting Guide, but the laptop simply turns on to a black screen and turns off after a few seconds and loops.
- I pressed and held the power button for a few minutes with the laptop not being connected to power, to maybe power cycle it.
- Followed whatever was suggested in the post , with the user having the same model of laptop as me.
As of right now, I'm open to doing anything to the laptop to try to fix it, as the laptop is almost a year out of warranty.
Thanks in advance.
