    Keyboard RGB issue - Dell g15 UEL 2 bios dump

    After a bios downgrade, the keyboard's RGB stopped working, now in the device manager the STM32 Bootloader device appears, I discovered that it is the rgb microcontroller, I believe that (STM32 bootloader) is because it does not identify the bios file (UEL2)

    Does anyone have the BIOS dump (UEL 2) of the Dell G15? It is responsible for the RGB keyboard.

              You need to program UEL1, programming UEL2 doesn't work. Have you tried with a new BIOS?

                  I just updated the bios, but without success.
                  in the bios update files, there is nothing related to the ELC firmware

                      You need to get it from another active device, or from the donor table. That's what I know.

                          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
                          ...

                          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...

                          I need a BIOS dump for the Samsung S49CG934SU monitor
                          by Habble7
                          The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                          Suspected Cause:
                          I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                          Troubleshooting Attempts:

                          Dell Latitude E5550 - Strange Internal LCD (BIOS?) Issue
                          by Eradicatus
                          I have a problem with my Dell Latitude E5550 laptop, in particular with its display.
                          This laptop has been sat under my desk (unused) for quite a while and I wanted to reinstall Windows and use it for some ad-hoc testing.
                          However, I am struggling with the display, which is playing up.

                          1) When the laptop is left switched off, after switching it back on the internal LCD does not work. No images are displayed at all - no DELL logo on POST, no messages, no Windows desktop. But I can hear that Windows starts up correctly, so no issues with the rest of the system - must be...
