Check if this file works (your file, patched), I've done this procedure a few times and it works for me everytime.

There must be a software tool to change serial, but I would try changing it in the dump. In this case the serial appears 8 times in the 16MB dump, 4 times in ASCII form and 4 times in UNICODE form.
I bet you are just modifying the serial that is in ASCII form:

ASCII: 35434734333131474B43 (hex)
Unicode: 350043004700340033003100310047004B004300 (hex)

I haven't used HxD, but it may have an option to search for Unicode strings... I use WinHex.
Look at my previous post, in this particular case you just have to add 00 to each hex byte, so if HxD doesn't have option for Unicode search, just do a hexadecimal search for:
350043004700340033003100310047004B004300

You can search both types in HxD.

You could also set the hp into mpm mode and then rewrite all information with wndmifit under winpe/windows. This works for me if i need to "correct" a serial number.

I have seen that a changed serial will be restored from the network chip after the second or third reboot! If this happens i have another solution.

I can enable mpm mode in your bios, let me know :woohoo:

I have also written a script which unlocks the bios in the correct way and also resets to defaults. This is done at around 8 or 9 location in the rom.

MODEL:          HP ProBook 650 G1
SERIAL:         5CG43xxxxx
SKU:            D9S34AV

--> PATCHING:              MpM_Mode

--> ROM PATCHED!

Your zip is a rar file! :angry:

This rom is unlocked and mpm is on. Make first a backup of your current bios if you fail to use wndmifit! If you flash this patched bios it will wipe out all info during first boot.

::After the backup::

1) remove cmos battery
2) flash unlocked bios
3) remove battery and ac (wait 5min), then ONLY use ac
4) write serial/model with wndmifit (commit & lock)
5) shutdown, remove ac (wait 5min)
6) connect ac, go into bios and set correct time/date (important!!!)
7) you need maybe to redo the commit step after the first boot...
9) connect cmos battery as last step

I`m using an RaspBerry Pi 3b with an attached 1602 lcd (i2c interfaced). All parts solid screwed on a heavy mdf base plate to get some weight. This is covered with an self designed 3d printed strong cover. I`m also using pomona clips, not the cheap ones. All my clips are changeable with one click. I don`t need and will a standalone unit. I can remote connect with putty or any ssh client. I have written a full menu featured remote interface. I have also compiled the most stuff like kernel, flashrom and other things by myself. It takes under 5secs till the boot process is finished.

The lcd shows ip and usefull status infos. Video output is fully disabled, only remote!
