Hey! We’ll stop the Arlo boot loop and get your system stable again (camera or SmartHub/Base Station). “Boot loop” can mean different things on Arlo, so I’ll ask a few quick questions and then we’ll follow the safest recovery path:

1) Which device is rebooting?
• An Arlo camera (Pro 2/Pro 3/Pro 4/Ultra/Essential/Wired) stuck on endless restarting?
• Or the Arlo base station / SmartHub stuck on rebooting (power light cycling, internet light never goes solid)?

2) What do you see?
• LED colors on camera (blinking amber, blinking blue, alternating blue/amber, solid amber)?
• In the Arlo Secure app: “offline”, “connecting”, “updating”, or “device not found”?

3) Power details (super important for boot loops)
• If it’s a battery model: is the battery charged, and are you using the original charging cable/power adapter?
• If it’s wired: is it on the correct adapter, and can you try a different outlet?

Once I know those, we’ll do: power sanity check → isolate camera vs hub → stop any firmware update stuck loop → resync/re-pair → only then factory reset if needed.

Got it — Arlo Pro 3 stuck on boot loop is usually one of these:

A) Power/charging problem (most common): the camera reboots when voltage dips. This happens with weak batteries, non-original chargers/cables, or a flaky outlet/adapter.
B) Firmware update stuck: the camera tries to boot, hits an update state, then restarts and repeats (often after an app update or hub firmware push).
C) Sync/auth mismatch: the camera loses its pairing state with the SmartHub and gets stuck cycling between “connecting” and “offline.”
D) Hardware/temperature edge cases: rare, but if the unit overheats or the battery has degraded, you can see endless rebooting.

We’ll fix it in a way that preserves your settings and recordings:
1) Confirm stable power (battery + charger).
2) Force a clean restart (not just “close the app”).
3) If needed, re-sync / re-pair the camera to the SmartHub.
4) Only if it still keeps rebooting: factory reset (last resort).

First question: is this Pro 3 plugged in on a charger right now, or running on battery only?

That “random cable” detail is a big clue. With Arlo Pro/Ultra models, a weak cable/adapter can cause reboot loop behavior while it tries to start up and draw power.

Step 1 — Stabilise power (do this before any reset)
1) Remove the camera from its mount and bring it close to the SmartHub (for later sync steps).
2) Remove the battery, inspect the contacts (no corrosion/dirt). Re-seat it firmly.
3) Charge using the original Arlo charging cable and power adapter if you have them. If not, use a high-quality wall adapter (not a PC USB port) and a short, good cable.
4) Let it charge for 20–30 minutes before judging results. A deeply discharged battery can cause repeated restarts.

Step 2 — Clean reboot sequence
• With the camera on stable power, remove the battery for 10 seconds, then reinsert it.
• Wait 2–3 minutes and watch the LED pattern. We’re looking for it to complete boot and become ready for sync (often a stable state, then blinking blue when pairing is triggered).

If it still boot-loops on known-good power, we’ll treat it as firmware update stuck or a pairing/auth issue and move to resync.

Perfect — alternating colors can point to a reset/update in progress state, or the camera trying to handshake with the hub and failing. Let’s confirm the hub isn’t the hidden culprit and then do a clean re-sync.

Step 3 — Quick SmartHub/Base Station sanity check
1) Look at the SmartHub LEDs: power should be solid, internet should be solid/normal for your model (no constant amber). If the hub is also unstable, you can get camera boot loop symptoms because it can’t complete pairing.
2) If the hub has been up “forever,” do a safe restart: unplug the SmartHub power for 30 seconds, plug back in, and wait 3–5 minutes for it to fully come online.
3) Make sure the hub’s Ethernet cable is secure and connected to the main router (not a guest VLAN or a flaky switch).

Step 4 — Re-sync the camera (often fixes “offline + boot loop-ish” behavior)
• Bring the camera within a few feet of the hub.
• In the Arlo Secure app: Devices → select the SmartHub → Add Device → choose your Arlo model → follow the prompts.
• When it asks for pairing, press the camera Sync button (short press) to enter pairing mode (usually blinking blue).

If the camera never stays stable long enough to pair, we’ll do a controlled factory reset next (still recoverable).

When an Arlo camera can’t stay in pairing mode and keeps restarting, a factory reset + re-sync is the cleanest way to break the loop — especially if the firmware state or pairing token is corrupted.

Step 5 — Factory reset the Arlo camera (safe method)
Do this with the camera on stable power (original charger), close to the hub:
1) Make sure the camera is powered on.
2) Press and hold the camera Sync button for about 15 seconds until the LED shows the reset pattern (commonly blinking amber).
3) Release and wait. The reset can take 15–45 seconds, sometimes a bit longer if it’s clearing a stuck state.
4) In the Arlo Secure app, remove the “ghost” camera entry if it exists (so the app doesn’t keep trying to talk to a dead pairing).
5) Now re-add it: Devices → Add Device → pick camera model → press Sync (short press) to pair.

Extra tip for boot loops: after the reset, give it 2–3 minutes before pairing so it can finish booting and settle. Rushing pairing while it’s mid-boot can look like “stuck on connecting.”

If it still reboots immediately after reset, we’ll focus on battery health and power delivery (some Arlo models won’t behave normally without a healthy battery seated).

Yes — a degraded battery can absolutely cause Arlo boot loop symptoms, and on some battery-based Arlo models the battery isn’t just “backup,” it’s part of the power path. If the battery can’t hold stable voltage, the camera can restart even when plugged in.

Step 6 — Battery & charging checks (to stop random reboots)
1) With the camera plugged into the original Arlo charger, leave the battery installed and let it charge for at least 60 minutes. Low battery + reboot loop can take time to recover.
2) If you have a second Arlo battery (from another camera), swap batteries as a test. If the boot loop follows the battery, you’ve found the root cause.
3) Check for “charging fault” messages in the app (if it stays online long enough). Those often point to cable/adapter issues or battery problems.
4) Avoid USB ports on TVs/routers or very long thin cables — they can drop voltage and trigger restarts.

Step 7 — Reduce connectivity flapping (prevents ‘offline → reconnect → reboot’ patterns)
• Keep the camera temporarily close to the SmartHub to eliminate range/interference as a factor.
• Confirm the hub isn’t showing amber connection LEDs (that would indicate a camera link issue).

If a battery swap fixes it, that’s the most reliable long-term solution. If it still restarts with a known-good battery, we’ll check whether the hub firmware or app is repeatedly forcing reconnects.

Great sign — that points strongly to power stability (battery) as the main boot-loop trigger. Now, the “connecting” delay is usually the hub’s path to the internet/cloud.

Step 8 — Make SmartHub connectivity rock-solid (stops ‘connecting’ delays)
• Ensure the SmartHub is on wired Ethernet directly to your main router (not a flaky extender port). Swap the Ethernet cable if it’s old — bad cables cause intermittent cloud drops that look like camera issues.
• If your router has security filtering, “IoT protection,” or aggressive firewall settings, it can interrupt the Arlo cloud session. As a test, temporarily disable those features for 10 minutes and watch if “connecting” disappears.
• If you use custom DNS/ad-blocking (Pi-hole/NextDNS), allowlisting Arlo endpoints can prevent slow cloud handshakes.

Preventing another Arlo reboot loop
• Keep batteries healthy and seated properly.
• Use original charging accessories for Pro/Ultra series.
• After firmware updates, avoid power interruptions during the first 10–15 minutes while devices settle.

If you tell me your SmartHub model (VMBxxxx) and router/mesh type, I can point to the exact setting that most often causes “connecting” loops.

Yep — Arlo base station stuck on boot loop is a common “whole system offline” scenario, and the steps are similar but focused on power + Ethernet + reset timing.

If the SmartHub/Base Station is stuck rebooting (quick recovery path)
1) Unplug power AND Ethernet from the hub, wait 60 seconds (let capacitors fully discharge).
2) Plug power only back in first. Wait 2–3 minutes and watch LEDs. Then connect Ethernet.
3) Try a different power outlet and, if possible, a different compatible power adapter (a weak adapter can cause repeated restarts).
4) Swap the Ethernet cable and try a different router port (a bad port/cable can keep the internet LED unstable).

If the hub still boot-loops:
• Use the hub’s reset button/pinhole reset (model-dependent). Do it only after confirming power is stable, because resetting mid-power-fault can make onboarding harder.
• After reset, you may need to re-onboard the hub and re-sync cameras.

The exact LED pattern matters a lot (solid amber vs slow blinking amber vs alternating blue/amber). If your friend tells you the LED colors, we can pick the correct “reset level” without guessing.

Love that outcome — and it matches what we see most often with Arlo stuck on boot loop: power stability first, then pairing/cloud connectivity.

Summary: fix an Arlo camera boot loop by stabilising power (healthy battery + original charger), then reboot and resync to the SmartHub. If pairing won’t complete or the camera keeps cycling, do a controlled factory reset and re-add it in the Arlo Secure app. For “connecting” delays, treat it like a network path issue: hub power, Ethernet cable/port, and router filtering/DNS settings.
