Added RTX 3070 firmware for this Laptop straightly dumped from chip with CH341A.
If i fix my BIOS i will add dump of that too. (Unfortunely chip is dead for some reason. I cant even read it with CH341A. Tried every version.)
Ordered a new one Winbond W25Q128JVSIQ 128M-BIT as replacement. (Couldn't find the Winbond W25Q128FVSQ but this should do the trick if CH341A will be able to detect new BIOS chip because old one does not getting detected.) Gonna flash the bios that i extracted from orginal BIOS Firmware first then solder it. If it's works, i will upload the contents of the chip here too. BIOS FOR ACER NITRO 5 AN515-45
Suggested Version: 1.06 (For Low Temps)
Suggested Version: 1.10 (For extended support to Windows 11 Sun Valley 2 Update)
İndir / Download

Downloaded version is only for indirect installs. (Installing from running laptop, Installing with flash drive via BIOS Recovery Crisis Mode etc.)

If you gonna use ch341a use the version in code section in upper. That is a extracted firmware exactly sized for flashing with CH341A. (BIOS VER: 1.10)

How did i get CH341A version?

Opened .EXE file with 7ZIP extracted. Found a abobios.bin.
Opened a Windows CMD same folder.
extractor.exe abobios.bin extracted_abobios.bin
Then before i use with Neo Programmmer 2.2.0.10 renamed file to abobios.bin
You don't need to trust me. You can just do the same thing with any spare computer.
I don't freaking know that why this is not mentioned anywhere...
I'm still waiting to test this while waiting for shipment of missing single tool.
Extracted bios file and BIOS chip is exactly same sized.

How to enter BIOS Recovery Mode / BIOS Crisis Mode?

While turned off. Keep Press FN+ESC for BIOS Crisis Recovery Mode same time press and release power button.
This laptop looks for BIOS file named BIOS.fd or ME.fd in USB drive formatted as fat32.

How to find BIOS file name for similiar laptops?

Extract the BIOS file from EXE form with 7ZIP and open the abobios.BIN file with the HxD editor.
Press CTRL + F and search for .fd
In this way, you can find out which BIOS file name the laptop is looking for in BIOS restore mode.

Included Versions: 1.03, 1.06, 1.08, 1.10

You can switch any version of your wish.
You can downgrade BIOS with this.
I'm not accepting any responsibility but i tested them in AN515-45-R4SE
So they should work on any Nitro 5 AN515-45
Pick a version then stick with it.
Don't constantly change BIOS version since you are asking for bricking your computer.
First version of BIOS is always superior for me because it will went in more testing during development.
