ANY ISSUES REPORTED RELATING TO BEING ENROLLED WHILE TRYING TO USE THIS WILL GET CLOSED IMMEDIATELY</b></p> <h3>How do I use this?</h3> <p>To use KVS, you must download your shim from <a href="https://dl.kxtz.dev/ChromeOS/shims/KVS/">kxtz' shim mirror</a></p> <p>After downloading, flash your USB/SD with the file, I recommend Chrome Recovery Utility.</p> </div> <div class="faq"> <h3>FAQ</h3> <h4><p><b>Q: </b>Will this brick my device?</p></h4> <p><b>A: </b>No, KVS has no way to permanantly brick / hard brick a device. At most, it will make ChromeOS stop booting, but you will still be able to boot shims to recover the kernver index.</p> <h4><b>Q: </b>What kernvers are there?</h4> <p><b>A: </b>There are 4,294,967,296 possible kernel versions (0x00000000 - 0xFFFFFFFF)</p> <h4><b>Q: </b>What versions can I downgrade to with kernver _</h4> <p><b>A: </b>Heres what versions you can downgrade to with each official kernver</p> <p>kernver 0: any</p> <p>kernver 1: any</p> <p>kernver 2: 112 - 119</p> <p>kernver 4: 125 - latest</p> <h4><b>Q: </b>What is the difference between kernver 0 and kernver 1?</h4> <p><b>A: </b>literally none, its just cool to see</p> </div> <div class="credits"> <h3>Credits</h3> <p><b>kxtzownsu</b> - Writing KVS</p> <p><b>OlyB</b> - Helping me with the shim builder, most of the shim builder wouldn't exist without him.</p> <p><b>Google</b> - Writing the <code>tpmc</code> command</p> </div> <div style="padding-bottom: 3%;"></div> </div> </body> </html>
