Re: BIOS REQUEST HP 430 g3

empty one , you waste your time .
your bios is near bios battery ...the only one .

Re: BIOS REQUEST HP 430 g3

Here, read post #184 https://www.badcaps.net/forum/showth...=79956&page=10 .If you can`t read it using the clip then you`ll have to desolder the bios.

With some programmers you need to do this:
*Remove battery
*Attach charger
*Turn on laptop and go to F1, F10 or wherever you like
*Turn off laptop holding down power button (DO NOT REMOVE CHARGER)
*Attach programmer
*Read bios chip content
*Use verify function or read content one more time and compare using hex editor software
*If all is okay, use HPUnlocker tool on the VERIFIED bios dump
*Write the xxx_unlocked.bin file
*Verify bios content


You must always make sure you verify everything you read/write, I cant stress this enough.
And those few first steps are mandatory with some programmers unless you unsolder the chip.

Re: BIOS REQUEST HP 430 g3

Ok,
so the process is
1 desolder the chip and solder to the programmer
2 connect to software via usb and read the chip.?
I dont understand what im doing wrong.
Maybe the drivers.? I did install them.

Re: BIOS REQUEST HP 430 g3

Thnx but I have desoldered the chip and soldered directly to the programmer as advised earlier in the thread.
What could be the cause of the empty reads.?

Re: BIOS REQUEST HP 430 g3

What are you attaching your programmer to ? ,maybe it isn`t proving enough amperage

Well im using one of these with the bios chip soldered to it.
Attaching it to my ACER laptop.
Maybe its the installation thats the issue.?
I assume my laptop will provide enough voltage?

This is exctly what I am doing although with a different programmer.

Re: BIOS REQUEST HP 430 g3

guys this one may be correct..
pls check..thnx

Re: BIOS REQUEST HP 430 g3

I think I was using the wrong version for the black pcb programmer and also the driver with windows 10 had issues.
hope you guys still up..really want this to work..

Anyone around?

Your bios backup is corrupt near the end. Make another backup to make sure,and post it.

Here is the new read. Is it the same.? size seems different.

Re: BIOS REQUEST HP 430 g3

Hi guys..is this correct flea?

Re: BIOS REQUEST HP 430 g3

The backup appears to be good although the bios itself is corrupt. I can`t find a password in it,i could be wrong.

There def is an admin password on the machine.
hpunlocker tool has generated a new file for this bin,shall I write the chip with that and test.?

Re: BIOS REQUEST HP 430 g3

Yes go for it.

Re: BIOS REQUEST HP 430 g3

That BIOS definitely looks corrupt. If the laptop is working, there's an issue when dumping the BIOS and I'd definitely not feel safe flashing the BIOS.

Re: BIOS REQUEST HP 430 g3

Whats the worst case scenario.?
What would make the bios corrupt in the case of the attempted dump?
