+<hr />
+<p class="text">TWRP requires an unlocked device - read the above topic and ensure you have your device unlocked and <b>adb/fastboot</b> ready (read above topic if not)!</p>
<p class="text">Download the correct image file and copy the file into the same folder as your adb and fastboot binaries. Rename the image to twrp.img and type:</p>
<p class="code">fastboot boot twrp.img</p>
<p class="text">This will boot up TWRP but for the moment in memory only. To complete the installation and making it persistent:</p>
-<p class="text">Copy the twrp.img to your device while still in twrp (e.g. with a file explorer or by typing adb push twrp.img /sdcard)</p>
-<p class="text">Flash the twrp.img with the twrp GUI to the recovery(!) partition (choose the button at the bottom named 'Image' to show the copied image)</p>
-<p class="text">done. You can now reboot into recovery again to check it has worked.</p>
-<p class="text">Note many devices will replace your custom recovery automatically during first boot. To prevent this, use the key combo <a href="https://forum.xda-developers.com/showpost.php?p=68249027&postcount=3" target=_blank>explained in this FAQ</a> to enter recovery. After typing <span class="code">fastboot reboot</span>, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.</p>
+<p class="text">Copy the twrp.img to your device while still in twrp (e.g. with a file explorer or by typing <i>adb push twrp.img /sdcard</i>)</p>
+<p class="text">Flash the twrp.img with the twrp GUI to the recovery(!) partition (choose the button at the bottom named <b>'Image'</b> to display the copied image)</p>
+<p class="text">It is highly recommended to verify your TWRP installation by booting into Android <b>NOW</b>. When Android is booted up execute: <i><b>adb reboot recovery</b></i><br />
+or in an Android terminal app just execute: <i><b>reboot recovery</b></i></p>
+<p class="text">If you see TWRP afterwards then you are safe to use the key combo described in the next topic. If NOT: <b>RE-DO all steps!</b> DO <b>NOT</b> USE THE KEY COMBO described in the next topic until the reboot into recovery worked!</p>
+
+<div class='page-heading'>Boot into TWRP with a key combination:</div>
+<hr />
+<p class="text">Ensure you have validated the TWRP installation first! Check the above topic and proceed when verification was successful <b>only</b>!<p>
+<p class="text">After installing TWRP correctly, you will still have the original LG factory reset screen/menu booting before TWRP, every time! So the correct and only way to get into TWRP with a key combo is to select <b>two times "Yes"</b> in the official LG factory reset menu, and only then you will get into TWRP (This a restriction by LG. There is no key combo available in some / all / most LG devices to boot directly into recovery and so TWRP).</p>
+<p class="text">Power down and pull out the battery. Do not forget to remove any USB cable. <br />
+Press power down and hold it down. Put battery back while keeping vol down pressed. Press power button and keep now both buttons pressed. Directly you see the LG logo the first time just release <b>only</b> the power button for 1 second ( do not release vol down ) and then press power again and keep both pressed until you see the factory reset screen. Proceed like you would to the factory reset (as long as TWRP is installed it will not reset but just open TWRP instead).
