        Post EC content (U368)...probably is on the other side of the PCB.
        U367 is the BIOS chip.

                    Hello,

                    The result is the same; after running the sent file through ME Analyzer, it is still in the "Initialized" state. I started over from my original main dump and replaced the Intel ME, PMC, and PCHC sections. CSE ME Version 15.0.42.2235 -> 15.0.55.2751 PMC Version 150.1.20.1041 -> 150.1.20.1042 PCHC Version 15.0.0.1021 -> 15.0.0.1021

                    After restarting, the NVME drive was no longer detected, and upon the next reboot, the PC failed to start entirely. I therefore reflashed the main BIOS.

                    I managed to restart again, though a few error windows appeared. Thinking I could improve the situation, I updated the BIOS via a USB flash drive using the latest version found on the HP website. All the update steps completed successfully, and then the PC shut down but could not be restarted. I should mention that I had not yet reconnected the battery.

                    I am attaching the two ME Analyzer files; there may be a compatibility issue with the downloaded versions.

                    Best regards,

                    S/N: 5CG21032H3
                    Hello everyone,

                    After several unsuccessful attempts, maybe I should start from a Matched Dump?
                    My motherboard is: CORVETTE-6050A32175101-MB-A01 (A1)
                    S/N: 5CG21032H3
                    Could you please help me?

                    Best regards,

                          Thanks a lot.
                          It works, logo appears fast, but "hp endpoint security controller problem" appears after that. Factory defaults do not work. Could you help me about that?

                                        Help Disabling Flash Protection Range Registers on Lenovo P360 Tiny BIOS
                                        by abhorsen
                                        Hey guys,

                                        Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.

                                        Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27

                                        Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit...

                                        HP Omen 16-wdxxxx Bricked After Successful(?) BIOS Flash
                                        by bad0menz
                                        I wanted to remove the BIOS password on my Omen 16, so I used a ch314a to flash a modified BIOS file. Based on readings, the chip seems to have been programmed correctly, however the computer won't POST or boot—no fan, and either the power button blinks 1 long 1 short, or the capslock blinks once before shutting off.

                                        There shouldn't be any shorts or physical damage from what I can tell

                                        This Omen probably has HP SureStart Gen4, a firmware-level security feature embedded in the BIOS, however I've been told that "just by flashing to the dedicated flash there should...

                                        Hello everyone,

                                        I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.

                                        This is NOT a BIOS password removal request.

                                        I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.

                                        Can I flash a working BIOS from one computer to another of the same make, model, etc?
                                        by TyMercer
                                        Apologies if this is the wrong forum, but I'm not looking for a specific BIOS file, I'm trying to understand how one makes a clean BIOS file. So here's the background. I have 2 HP EliteDesk 800 g2 mini 35w pcs. One is working fine; the other doesn't have display out or working USB's nor does it have any flashing error lights. The CPU does get worm enough to cause the fan to spin up, so I think it's posting, but I just don't know. I had it working at one point but trouble started when I tried to put in a drive caddy that had a cooling fan on it. I thought it would be compatible but wasn't...
