    820-4924 BIOS HELP/Clean ME

    Hello!

    I have a 13' MBPr (A1502, 820-4924) that I managed to screw up the original BIOS file on...

    I found a dump-file on Google that works, however runs slow due to ''dirty'' ME: https://easyupload.io/988emq

    Can someone please help me with a clean ME bios file? =)
    My machines serial number is: C02T2P5LFVH3 (the SN in the DUMP ends on FVH5 so maybe needs adjusting?)

    Thanks in advance! =)

      See the ME firmware cleaning guide for ME firmware repositories and system tools https://www.badcaps.net/forum/showthread.php?t=88533

      See the link to piernov`s video on youtube "How to clean ME Region on Apple machines" and see his other video while you`re there "How to edit serial number on Apple machines" ,he shows you how to edit the serial and correct the checksum.

                      Hi all,

                      trying to diagnose a slow MBPr issue.

                      Can someone please clean the ME Region, I have removed the Flash and dumped the contents, and can share it.

                      I have tried to follow a tutorial from Youtube from Piernov but struggle with some of the installations.

                      Thank you

                          🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                          by macabook
                          Hello everyone,

                          I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                          🧩 Initial Issue
                          • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                          • External display (HDMI) shows
                          ...

                          [Problem/ Request] Bricked TongFang GK7MRFR BIOS
                          by cr4zychriss
                          Hello everyone,
                          I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
                          I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

                          by pirati
                          Hello everyone,

                          I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

                          When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

                          I decided to try flashing a new BIOS, but since I didn’t want to desolder...

                          I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
                          I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
                          The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
