NVIDIA BIOS Signature Lock Broken, vBIOS Modding and Crossflash Enabled by Groundbreaking New Tools
You can now play with NVIDIA GeForce graphics card BIOS like it's 2013! Over the last decade, NVIDIA had effectively killed video BIOS modding by introducing BIOS signature checks. With GeForce 900-series "Maxwell," the company added an on-die security processor on all its GPUs, codenamed...

"OMGVflash author Veii posted a comprehensive thread on the TechPowerUp Forums, which announces the first public beta of the tool, its development history, usage instructions, and some troubleshooting support. Find the thread here. The author has expressed interest in working with TechPowerUp on publishing future versions.
NVflashk author Kefi posted a similar comprehensive thread on TechPowerUp Forums, which can be accessed here.
OMGVflash and NVflashk are independently developed of each other. We've hand-inspected the binary code of both tools and they are free of any viruses or trojans. There's only few code modifications to the original NVFlash tool, to activate the bypass. There's no additional malware payload or anything similar. The file sizes are identical to the unmodified files. VirusTotal also confirms that these patches are legit.
Tampering with the vBIOS will void your graphics card's warranty. As with all modding, graphics card BIOS modding is not without risk, and meant for power users. It is fairly easy to recover from a broken flash, as all current desktop processors come with iGPUs that you can boot from, so you could flash a working BIOS onto the bricked graphics card. Just do remember to back-up your BIOS. You can use either of these tools to extract your current BIOS, or better yet, use GPU-Z for the task."
