Bios update failed. Bricked laptop

[minbal6]

Hello again Sirs,

I tryed with 4gb (kingston) fat-fat32, 16gb(sony) fat32 only, 1tb usb3 hard disk (toshiba, formated fat32 not NTFS).
I tryed cd's and fd with couple and only with 1 file (as it recommendated on this web page at recovery tutorial) nothing helped. One thing left to try is with fat32 hdd, but i dont have any of those free right now. So i must to say i have to wait for tools arrival. If i cant fix it i will buy new MB from ebay, becouse it's cheaper than take MB to service reprogram bioses. They asks for it 70 euros... becouse they have solder out chip, reprogram it and resolder it back.

When I said smaller/cheaper, I meant ones like 128MB-2GB, those have best chances of working.

You can make small FAT32 partition on the end of your drive currently installed, download any free partition software and make it at the very end of the drive (right side)

You wont need new motherboard, unless something fried on it, BIOS recovery tools is all you need (CH341A + SOIC8 test clip cable). If you took it to a shop for that, they don't need to desolder the BIOS either, only they say or do that so they can charge you more (Often they say this and don't even do it). And even if they did, this takes less than 1 minute to do + few minutes to program chip, so shouldn't cost so much by anyone, people are thieves!

Today I found 256mb and another 4gb old kingston flash drives. Tryed with both, but no luck. Also tryed with splited hdd and maked conclusion that it doesnt reads hard drives, becouse laptop readed hdd same amount time as ssd and rebooted.

Split HDD, what does that mean exactly? Did you make FAT32 partition on the HDD?

I'm in the same boat as op. About to order a CH341A + SOIC8.

[minbal6]

Yes, exactly. I maked fat32 partition, but sadly it wasn't worked either.

[Lost_N_BIOS]

FAT32 is best, but FAT16 will work too "Sometimes" so best to just stick to FAT32. Smaller and older is better, 128MB to 2GB = so cheap chips

If you made a FAT32 partition on your HDD and it's not working, then BIOS is bricked beyond recovery repair to function, you will need programmer and SOIC8 test clip w/ cable.

Hopefully, I'm not hijacking minbal6's thread, but can someone answer where I can get the BIOS file to be written on the chip after I receive the programmer?

[Lost_N_BIOS]

It has to be created, from your dumped BIOS. So do not write anything until you've dumped BIOS and someone has confirmed it's a good dump. Otherwise, you will loose your systems NVRAM, serial, UUID, and LAN MAC ID (possibly windows install key too if/when tied to serial within the BIOS)

Sometimes online BIOS download will run a board if flashed, and if taken out of capsule if within a capsule, but when you do that you always loose all mentioned above. Other times BIOS download online is only partial BIOS, and cannot be written directly to chip without being compiled into a full BIOS.

Uncheck Erase and blank check in CH341A software now, all versions, before your programmer arrives, that way no "Auto" erase mistakes can be made.

Read, verify and if "Chip and buffer match" save BIOS and have someone check for you. Do not write anything until you hear back your saved BIOS dump is a good BIOS, sometimes completely blank BIOS (FF or 00) can be "Verified" if program only reads that, so if you save that and think it's OK without checking and then erase all is lost.

Go slow, be patient, do it the correct way not the hard way

I'm not a programmer, so would it be possible for someone here to verify the dump? Also is it safe to post your system's information like that?

How many attempts on an average does it take to get a decent dump?
