Also, there is a newer version of the CH341a programmer which has a voltage switch and natively supports 5v, 3.3v, 2.5v and 1.8v.
#UEFITOOL INVALID BIOS IMAGE MOD#
If you are working with a 1.8v device and are using the common 1.8v adapter, the adapter correctly drops the programming voltages to 1.8v, so you do NOT need to do the voltage mod if working with 1.8v devices. When researching CH341a programmers, you will see that the common cheap black version has a design flaw which requires a modification to output 3.3v on the data lines. I didn't see this mentioned elsewhere, so thank you very much to the OP.
#UEFITOOL INVALID BIOS IMAGE SERIAL#
Preserving the serial information as described by the OP is very important for these HP laptops, because it contains important configuration info. I successfully recovered a similar HP laptop using this same technique mentioned in the OPs edit. It's difficult for a beginner, no doubt, but it can be done with a lot of effort. I was graciously assisted by some of the server's members, and that's pretty much how I, a complete beginner, was able to get this arduous process done.

The owner of that YouTube video also runs a Discord server where you can get more knowledge on how to do this procedure correctly. With that said, a great place to start would be with this video:
This is very much a last-ditch DIY repair, so I strongly suggest you remain cautious throughout the entire process any mistakes you make have the potential to permanently damage your system. Your hex addresses may be different, and in that case, you can request help from members of servers that specialize in these types of repairs for more help as to how to properly extract serial information. I just went ahead and used HxD, a hex editor, and copied over the serial information (which in my case was the data from hex address 00000000 to 0002a000) to the new BIOS image. bin file, you can either use a hex editor or you can use UEFITool. To add the serial information to the new. One thing to note is that adding the serial information is a difficult task once the chip is flashed - hence you should backup the original BIOS Firmware so you can extract the serial information and add it to the new BIOS Image before flashing it to the BIOS Chip. Here's a great resource to help find out what your Board ID is so you can flash the appropriate BIOS Image: Thankfully, HP Makes it easy to get the BIOS Firmware Image - you just run the HP BIOS Updater tool and select the option that says "Copy BIOS Image to any file location (Advanced Users)". bin file), and finally, flashing the new BIOS Firmware with the appropriate serial information added. This involved locating the BIOS Chip, figuring out what model it is, backing up the original BIOS Firmware (a. Using something called a CH341a Programmer, I was able to successfully repair the laptop.
I pressed and held the power button for a few minutes with the laptop not being connected to power, to maybe power cycle it.įollowed whatever was suggested in the post Here, with the user having the same model of laptop as me.Īs 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. 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'm running the laptop only off of AC Power as of right now. I removed the NVMe drive, battery, and reseated the RAM. Some things I have done to try to fix this: 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. I let the laptop sit and perform its reboot sequence, and the laptop turned off after a few minutes. When recovering the BIOS with F.42.Rev.A, however, it successfully recovered the BIOS and displayed "The system BIOS recovery is complete". I then repeated the process with versions F.47.Rev A and F.46.Rev.A only to receive the exact same error.
Upon analyzing the logfile, I got something that mentioned "Verify of Block 46 Failed". 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. 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. However, once the writing to the BIOS was complete, I got an error saying "Verification of flashed BIOS Image failed". I updated my BIOS to the latest version (F.48.Rev.A) through HP's official website. To preface things, I have an HP Pavilion Laptop, model HP Pavilion - 15-cw100.
