    need BIOS for ASUS Zephyrus GA503RM

    Hello everyone, I just replaced the bios chip on my laptop because the one I had got corrupted. I was wondering if anyone has the bin files to the GA503RM so that I could flash the new Bios chip? Thanks in advance!!

              It does not work. The program can't flash the bios with that bin. I get an error that says "File size larger than IC size". Looks like I need a file that has a size of 2097152. My bios chip is Winbond 25Q16JWNIQ

                Thats the wrong chip, its only 16 Mega bits (lower case b) . The 25Q16JWNIQ is 2MB , 2 MegaBytes

                  I was able to extract the old BIOS bin that was on the old chip but it is password locked. Anyway to remove the password?

                      Is that not a BIOS chip?

                        Its not the only chip on the board.That one is 2MB, you can`t fit a 32MB bios into it. That chip is for firmware,could be for the vBios,USB4 firmware,thunderbolt or whatever, but it aint the bios chip .I hope you havn`t erased that 2MB chip,and if you did i hope you made a backup first or you`re in big doo-doo

                          Got it. Can't really find another chip that looks like that so I assumed it was the BIOS chip.

                            First of all tell us what the problem is with your laptop? Corrupted bios or it's just password locked and you are trying to remove the password by programming clean bios?

                            Maybe you didn't know but there's many different (visually too) SPI NOR flash memory chips, not only the traditional SOIC-8 type as in your picture, like SOIC-16, DIP-8, WSON-8 (8x6), WSON-8 (6x5) and so on.

                            Most probably the bios chip in your laptop is WSON-8 (8x6):




                            Edit: Yes, it's certainly WSON-8 (8x6):

                              Thanks for pointing that out, I was having a hard time trying to find it. What’s the best way to flash it with the bin file that was sent to me without desoldering?

                                Can anyone help me with the PDF file of it8252e248a? My Asus GA503RM cannot use the keyboard and keyboard light. I found a website that has a PDF of the it8252e248a and its firmware. However I cannot download it. Can I post a link here to get help?

                                    This is the firmware error I read from the Asus GA503RM motherboard. Can you help me fix it. Thank you.

                                      Didn't turn on for me with this file. Original bios turns on no display then after a while shuts off then turns on again.

                                          Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

                                          I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

                                          Hi, my laptop wont boot at all
                                          With original bios no POST, only LED lights
                                          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                                          Some issues
                                          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                                          B- If updated from 500LN version 203 to 300, the battery stops being recognized

                                          Things I tried

                                          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                                          ASUS Zephyrus GX701LXS BIOS request
                                          by skipron.rm
                                          Hello everyone, trust you're doing well.

                                          I'm currently facing an issue with my ASUS Zephyrus GX701LXS, as it isn't posting.
                                          I've downloaded the latest BIOS version, "GX701LXS-AS.311" (v.311), from the ASUS website.
                                          However, there's a challenge – the file size exceeds the capacity of the BIOS chip, making it impractical for writing.

                                          The current BIOS dump ("GX701LXS.307 bios-dump.bin" find attached), is of version 307.
                                          My attempt to extract "GX701LXS-AS.311" using the "AMI_BIOS_GUARD_Extractor" was aimed at combining...

                                          Hello everyone I stupidly updated the bios on my Asus and it got corrupted.
                                          Can anyone edit the hex bios file for my device? My bios chip W25Q16JVSNIQ Winbond has a capacity of 16Mb but the bios file I downloaded on the Asus homepage is 32Mb. Can anyone help me edit the hex and adjust it for me so I can flash the bios, please?
                                          Thank you so muchπŸ˜₯
