              Wrong chip, this is Thunderbolt firmware
              Look for XM25RH256C or similar chip with "256" in the name
              It's on the back of the board

                  Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

                  Hello everyone,

                  I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                  This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                  I have opened the laptop and identified the main BIOS chip...

                  NT955XED (Samsung Galaxy Book2 Pro - 15.6) BIOS dump file Request
                  by Citymin
                  Hi all,

                  My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
                  The charging red LED lights up, but the charging screen doesn't show any indication.
                  When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
                  (I've tried removing the battery and resetting the device, but the issue persists.)

                  NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)
                  PCB model name : Venus2-15-5G(REV1.2), Venus2-15 ADL NPC

                  Looking for BIOS flash file for HUAWEI MateBook X Pro 2019 (MACH-WX9)
                  by maanee11
                  Hello Everyone,

                  I have HUAWEI MateBook X Pro 2019 (MACH-WX9) whose BIOS got corrupted i beleive. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need BIOS bin/hex file which i could use to reflash it externally via the flasher tool.

                  It seems like the support page of this model no longer exist: https://consumer.huawei.com/be/lapto...ro-2019/specs/

                  In the website, you can only see specs etc.

                  I have not tried to extract the BIOS dump yet as I want to see if there is any ray of sunshine...

                  Notice to users of XGecu TL866II Plus / T48 / T56 / T76 programmers regarding BIOS backup file size
                  by m1ch43lzm
                  Hi everyone
                  I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
                  Programmer models: XGecu TL866II Plus / T48 / T56 / T76

                  Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
                  There's also an extra OTP Secu.R...

                  Lenovo ThinkStation P520 BIOS file needed
                  by Forest79
                  Hello,

                  I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
                  The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

                  However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...
