alerich<p>Liebe Nerds,<br>kennt sich jemand gut mit <a href="https://norden.social/tags/UART" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>UART</span></a> etc aus? Ich versuche, <a href="https://norden.social/tags/valetudo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>valetudo</span></a> auf einem Xiaomi X10 Plus zu installieren. Leider kann ich das root PW nicht eigeben. Bei der Eingabe (egal wie) gehen immer einige Zeichen verloren. jemand im telegram channel schrieb was vom input speed oder so. ich habe aber brutal keine ahnung. hier die anleitung:</p><p><a href="https://valetudo.cloud/pages/installation/dreame.html#uart" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">valetudo.cloud/pages/installat</span><span class="invisible">ion/dreame.html#uart</span></a></p>

Martin Schmitt<p>Das ist ja mal der geilste Scheiß überhaupt. Ich habe so einen 0.5 mm Bindfaden aus Gummi verwendet, den ich mal für ein Handarbeitsprojekt angeschafft hatte, und es ist sowas von *göttlich*. Nix mit dem Lötkolben rumbraten, nix freihändig die Pins auf Press halten, Garantie voiden ohne Spuren zu hinterlassen.
