No bios backup

[ahbecan]

Hello everyone. I'm new to the forum. I'm not a data recovery expert and I don't have a professional tool. I only have NeoProgrammer. (CH341A) I have faulty hard disk with USB PCB. While transferring to donor pcb, the bios chip (SMD type) was damaged and I have no bios backup. Is there any chance of recovery? Can I use the roms in the forum?

Without other tools, you can't...

When you say the chip was damaged, what do you mean?

[ahbecan]

While removing it with a hot air gun, 2 legs were broken from the bottom. I can't solder.

also, what's the brand and model number of the disk?
some pics would help as well...

Depending on the damage It may be possible for those of us with better equipment and tools to repair the rom and recover it. Can you post an image.

I would use solder paste + thin magnetic wire to rebuild legs and solder the rom on SOP8 to DIP8 adapter as this

Magnetic wire:

the ends of the magnetic wire should be enameled before soldering

This would work only if a portion of those 2 pin is still visible on the chip.

If you don't have accessible surface pin anymore then you should scrap the edge of the chip around those pin using something like this:
for manual abrasion: https://www.ebay.com/itm/185074774898
or
for mechanical abrasion: https://www.ebay.com/itm/185392191061?

The last one is more dangerous, you might kill the chip definitely and fastly.
It is a method that i cannot recommend if you are not practical, even if it is simpler in my opinion

My best advice is to contact an expert as "pcimage" that resides in your country:

sorry for my english...
i mean that the enamel at the ends of the wire should be removed before soldering the wire
