    Help with BIOS update on Dell G15 5515 after chip replacement

    Hey everyone,

    I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.

    The BIOS is currently at version 1.22.1, and I wanted to update it. I downloaded the latest BIOS version from Dell Support using my ST: FQZMYJ3, but when I tried to run it, it says "unsupported system." I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.

    When I check the BIOS using the F12 menu Flash Utility, it shows as an Alienware M15 Ryzen ED R5, even though everything else recognizes it as a Dell G15 5515.

    I tried using the RCV file to do a recovery since it seems like just a platform ID mismatch. I formatted a 2GB USB stick as FAT32, put the BIOS_IMG.RCV file on it, and pressed CTRL + ESC. The side light flashes 4 times white and 3 times orange, but nothing happens.

    Don’t hate me , but after some research (I’m a prompt engineer, so yes… I chatgpt’d it), it seems like I probably can’t fix this on a software level. Looks like I’ll need to reprogram the BIOS, but I have no clue where to find a proper .bin file for my device. I also can’t ask Dell Support because it’s a second-hand laptop with no proof of purchase.

    I’m hoping someone here might know a trick to fix this on a software level or could kindly share the .bin file for the Dell G15 5515.

    Thanks in advance!

          ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
          by DynaxSC
          Hi

          I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
          The SPI chip is an Winbond 25Q256JWEQ model (1V8).
          The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
          The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

          I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

          Dell 9010 MT BIOS Update Always Fails
          by mikeybass
          Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...

          Dell G3 3579 BIOS chip ID
          by ezenia
          Hello,

          I bought a Dell G3 3579 eBay. The fault was not mentioned and it did not come with charger. Before trying to power off battery, I did some basic checks on the coils (in resistance mode) to see if there was any short. None were reading short. Decided to power the board to see if anything happened. The keyboard backlight came on. About 5 seconds later, the fans begin spinning at max speed. The white LED comes on at this time, stays solid for a bit and goes off. Fans continue to spin at max. Display is black (no backlight). If I hold down power button, board goes off. I did give...

          Dell G15 5515 RGB Keyboard Not Detected (Compatible Keyboard, Possible BIOS/EC Issue?)
          by NotEnough
          Hi everyone,



          I'm working on a Dell G15 5515 (Ryzen 7 5800H, RTX 3050 Ti) and recently installed a compatible 4-zone RGB keyboard and controller (for Dell G15 5510/5511/5515 models). While the keyboard functions for typing, the RGB lighting is not detected by Alienware Command Center (AWCC), which displays “No AlienFX devices found.”



          What I've Tried So Far:
          • Reseated the cables.
          • Reinstalled AWCC and AlienFX services.
          • Attempted BIOS downgrade but no improvement.
          • Inspected ribbon cables for damage.
          • Explored the possibility of BIOS or
          ...
