  "content": "(Written as if you are sitting at the browser, clicking through Umbrel, with **no SSH** and **no guesswork**.)\n\n#### This manual covers two cases:\n\n1\\. Normal failure recovery (most common)\n\n2\\. Full re‑install / new device (clean slate)\n\n#### What you must have **before you start**\n\n✅ Lightning seed (24 words)\n\n✅ `channel.backup` file\n\n✅ Access to Umbrel UI `umbrel.local` or IP)\n\nIf you are missing **either the seed or SCB**, stop — recovery cannot be done safely.\n\n### CASE 1 — Umbrel is running, LND data is lost or broken\n\n(This includes corrupted Lightning DB, failed updates, or stuck LND.)\n\n#### Step 1 — Open Umbrel dashboard\n\n* Go to: `http://umbrel.local`\n\n* Log in\n\nYou should see the main app grid.\n\n#### Step 2 — Open **Lightning (LND)** app\n\nClick **Lightning** (or **LND** if named explicitly)\n\nIf LND detects missing data, you may immediately see a \\***recovery prompt**\n\nIf not, continue manually.\n\n#### Step 3 — Trigger recovery mode\n\n*Click* **Settings** ⚙️ inside the Lightning app\n\nChoose **Restore Wallet** or **Recover Wallet**\n\n* Wording may vary by Umbrel version\n\n* This option appears only when LND is uninitialised or reset\n\nUmbrel now switches into **Lightning wallet setup mode**.\n\n#### Step 4 — Choose **Restore existing wallet**\n\nWhen prompted:\n\n*Select\u0026#x20;*“**Restore existing Lightning wallet**”\\*\n\n\\* NOT “Create new wallet”\n\n##### Step 5 — Enter your **Lightning seed**\n\nYou will see a seed entry screen.\n\nDo the following:\n\nEnter all **24 Lightning words**\n\n* Ensure correct order\n\n* Confirm spelling carefully\n\nClick **Continue**.\n\n✅ At this moment:\n\n* Your Lightning node identity is restored\n\n* No channels are restored yet\n\n* Funds are not touched\n\n###### Step 6 — Import **channel backup (SCB)**\n\nNext screen:\n\n* **Upload channel.backup**\n\n* Choose the SCB file you previously saved\n\nClick **Import**.\n\n✅ Umbrel will confirm:\n\n* Backup imported successfully\n\n* Number of channels detected\n\n#### Step 7 — Confirm force‑close recovery\n\nUmbrel now warns you (wording varies):\n\n\\\u0026gt; “Channels will be force‑closed and funds recovered on‑chain”\n\nYou must:\n\n✅ Acknowledge this\n\n✅ Confirm recovery\n\nClick **Start Recovery** / **Confirm**.\n\nThere is no alternative path — this is intentional.\n\n#### Step 8 — LND restarts automatically\n\nUmbrel will:\n\n* Restart Lightning\n\n* Begin peer recovery connections\n\nYou may see:\n\n* “Recovering channels”\n\n* “Waiting for force‑closes”\n\nThis phase:\n\n* May take minutes to hours\n\n* Requires Bitcoin node connectivity\n\n#### Step 9 — Monitor recovery\n\nInside Lightning app:\n\n* Channels appear as `pending close`\n\n* Status messages update automatically\n\nNothing else to click.\n\n#### Step 10 — Funds return on‑chain (after timelocks)\n\nAfter force‑closes confirm:\n\n* Funds appear in the on‑chain wallet used to fund channels (Bitcoin Core on Umbrel, or whatever external wallet originally funded the channels)\n\n* Timelock period applies (often \\\\\\~1–2 weeks)\n\n✅ Recovery complete\n\n❌ Channels are permanently gone (expected)\n\n### CASE 2 — Full Umbrel reinstall or new device\n\n(This is the more common true disaster scenario.)\n\n#### Step 1 — Install fresh Umbrel\n\n* Install Umbrel on new disk/device\n\n* Complete initial setup\n\n* Log into the dashboard\n\nDo **not** install apps yet.\n\n#### Step 2 — Install **Lightning (LND)** app\n\n* Open **App Store**\n\n* Install \\***Lightning**\n\nUmbrel launches Lightning in **uninitialised mode**.\n\n#### Step 3 — Choose **Restore wallet**\n\nYou will be prompted:\n\nSelect **Restore existing wallet**\n\n**NOT** “Create new wallet”\n\n#### Step 4 — Enter Lightning seed\n\nSame as Case 1, Step 5:\n\n* Enter all seed words\n\n* Confirm order\n\n#### Step 5 — Import channel backup\n\nSame as Case 1, Step 6:\n\n* Upload `channel.backup`\n\n* Confirm import\n\n#### Step 6 — Confirm recovery + force‑close\n\nSame as Case 1, Step 7.\n\nUmbrel/LND now:\n\n* Connects to former peers\n\n* Requests force‑close of all channels\n\n#### Step 7 — Wait for on‑chain settlement\n\nNothing else to do in the UI.\n\nLightning app will show:\n\n* Recovering → Closed channels\n\n* After timelock: zero channels, full balance on‑chain\n\n##### What you should **never** see in Umbrel UI (by design)\n\nThe following actions are intentionally impossible in Umbrel, because they would be unsafe if channel state has been lost:\n\n❌ “Restore channel balances”\n\n❌ “Resume channels”\n\n❌ “Undo force‑close”\n\n❌ “Restore Lightning DB”\n\nIf you ever see claims suggesting otherwise, something is wrong.\n\n#### Quick visual checklist (mental)\n\n**Correct recovery flow always looks like:**\n\n###### Install LND\n\n→ Restore wallet\n\n→→ Enter Lightning seed\n\n→→→ Import channel.backup\n\n→→→→ Confirm force‑close\n\n→→→→→ Wait\n\n→→→→→→ Funds on‑chain\n\nIf **any step is skipped**, recovery is unsafe.\n\n#### Why Umbrel UI is intentionally strict\n\nUmbrel intentionally:\n\n* Forces seed first\n\n* Forces SCB second\n\n* Forces destructive recovery\n\nThis prevents:\n\n* Accidental stale‑state broadcasts\n\n* Channel penalty loss\n\n* User‑error recoveries\n\n###### Safety \u003e convenience.\n",
