Holy Stone HS720G: Random restart

By Sai Kiran Pandrala · reviewed by Sai Kiran Pandrala, Editor Last verified: 2026-05-30

What's happening

You hit random restart on your Holy Stone HS720G. This is one of the more common issues users report with this Drones category, and most of the time it's recoverable without a service centre visit.

Quick checks first (5 minutes)

1. Power-cycle: unplug for 60 seconds, plug back in, retry.
2. Check the obvious: cables seated, batteries fresh, switches on, breaker not tripped.
3. Try a different known-good accessory (cable, remote, app, network) to rule out an external cause.
4. Check the Holy Stone status page / community forum for known outages or release-notes for your firmware.
5. Note the exact symptom and any error code on display , you'll need it if escalation is required.

Step-by-step fix

1. Identify the trigger. Did this start after a firmware update? After a power surge? After a software / app change? Each of these has a different root cause.
2. Apply the safe fix first. For most "random restart" cases on a Holy Stone HS720G, the working sequence is:

- Soft reset (power-off, wait, power-on).

- App / firmware update to the latest stable release from the official Holy Stone support page.

- Re-pair / re-discover the device via the Holy Stone companion app if applicable.

1. If the soft fix fails, do a controlled hard reset. Back up settings + data first. Then factory-reset following the Holy Stone HS720G manual. Re-enrol from scratch.
2. Test the suspect path. Reproduce the original failure deliberately to confirm the fix held.
3. Document the outcome. Note what worked. If the issue returns, you have a faster path next time.

When to call Holy Stone support

• Issue returns within minutes of a fix.
• Device shows a hardware error code on display.
• Visible physical damage, burn smell, or swollen battery.
• Out-of-box failure within the warranty window.

Avoid recurrence

• Keep the firmware on the latest stable channel.
• Use a surge-protected outlet, especially in India where line voltage swings hard.
• Avoid third-party accessories that aren't certified by Holy Stone.
• Schedule a periodic maintenance check (clean filters, replace consumables, recalibrate where applicable).

Frequently asked questions

How long should this take?

Most users get through the procedure in 15-30 minutes. Allow longer if you're doing it for the first time on this specific model.

Will this work on older variants of the same model?

Most steps apply across firmware generations. Menu paths may shift; use the official manual for your specific revision.

What if my variant is region-locked?

Check the model code on the rating plate. Region-locked variants sometimes have features disabled. The brand support portal will confirm what's available for your region.

Does this void warranty?

Operating the device per the user manual and applying firmware updates from the official brand portal does NOT void warranty. Opening sealed components, third-party repair, or unauthorised mods can void warranty.

Common patterns we see

When this symptom shows up on a Holy device, three patterns repeat:

1. Recent firmware update changed behavior — the symptom started within a week of an OTA push. Rollback or wait for the hotfix. 2. Environmental trigger. temperature, humidity, line voltage, network changes. Look at what changed in the environment. 3. Cumulative wear, components like batteries, gaskets, fans degrade over time. Replace the consumable rather than chasing a software fix.

Knowing which pattern applies saves time on the wrong fix.

Safety + preconditions

Before any work on a Holy device:

• Unplug from mains for any internal-access procedure.
• Discharge stored energy (capacitors in PSUs, residual battery charge) per manufacturer guidance.
• Use ESD-safe handling for boards and modules: no carpet, no wool sleeves.
• Avoid moisture; never apply liquids near vents or connectors.
• If you smell smoke, see scorch marks, or feel uneven heat, stop and escalate.

Quick verification

Before you walk away from a Holy device fix, run through:

1. Reproduce the original trigger, does the issue reappear? 2. Check the device's status / health screen for any new alerts. 3. Confirm paired devices (app, hub, controller) reconnected. 4. Save / commit any configuration changes per the device's normal workflow. 5. Note the change in your maintenance log with date + firmware version.

Escalation guide

For a Holy device, the right escalation depends on impact:

• Cosmetic / minor: log a ticket via the Holy app or web portal. Response 1-3 business days.
• Mid-impact: phone support. Have your serial number ready.
• Critical (production down, safety issue): in-person dealer / TAC visit. Bring proof of purchase.
• Out of warranty: third-party repair shop with manufacturer-certified technicians.

More frequently asked questions

Will the procedure work on the international variant?

Some features and firmware paths are region-locked. Check the model spec sheet to confirm your variant supports the menu option referenced. If you're outside the US/EU, look for the regional support portal.

How long does this fix usually take?

Most users complete the steps in 20-45 minutes the first time, and 5-10 minutes on subsequent runs once the menu paths are familiar.

Why is this happening on a brand-new unit?

Out-of-box defects do occur. If you've owned the device under 30 days and the symptom persists after a factory reset, escalate to the seller for replacement under DOA terms before opening a manufacturer support case.

Should I update firmware first or last?

Update firmware first if a release note specifically mentions your symptom. Otherwise, finish the troubleshooting flow first, then update; that way you can isolate whether the update or the underlying fix solved it.

Will this void my warranty?

Applying official firmware updates and following the user manual will not affect warranty. Opening sealed components, jumping safety circuits, or using third-party parts can void warranty in most jurisdictions.

Field notes from real Drones incidents

When I work on Holy Stone HS720G: Random restart the rhythm I lean on is the one I have built over years of these tickets. Drone misbehaviour after a firmware update is real and frequent. I never push aircraft + remote firmware on the same day a flight is planned. Single-cell voltage divergence is the earliest warning a flight pack is failing; the app's percentage display is too coarse to catch it.

Tools I actually reach for

For Holy Stone HS720G: Random restart on Drones the cheapest signal I can land usually comes from RC transmitter calibration menu, then Manufacturer flight controller utility, GPS log download (DAT / TXT), Companion app diagnostics when RC transmitter calibration menu cannot see the layer the fault sits in, and Battery cell-voltage reader for the cases where neither of those answers cleanly. That ordering is not academic. It matches the layers the failure tends to surface through, so the cheap signal lands first and the heavier tooling only comes out when the simpler answer does not hold up under scrutiny.

Verification I run before I close the ticket

Before I mark Holy Stone HS720G: Random restart resolved on a Drones unit, the verification loop below is what I actually run. Each step proves a different layer is green, and the order matters - the cheap checks gate the more expensive ones.

IMU and compass calibration on a non-magnetic surface

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Hover test in P-mode at 2 m for 30 seconds before any aggressive flight

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Single-cell voltage check before every flight on aging packs

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Firmware version check on aircraft, remote, and battery

Only when every line above runs clean do I close the ticket and update the runbook with the timestamps.

Where I check first when the docs disagree

When two sources contradict each other on a Drones detail, the disambiguation order I lean on is stable. I usually start at manufacturer firmware archive for the ground-truth view on Drones. I usually start at FAA / DGCA notices for the airframe class for the ground-truth view on Drones. I usually start at manufacturer support portal for the ground-truth view on Drones. Random blog posts and reseller wikis are signal, not ground truth, and I treat them as such until the references above either confirm or contradict the claim.

Pitfalls I have walked into on this exact path

The shortcuts that look smart on Holy Stone HS720G: Random restart have a habit of biting back. The pitfalls below are the ones I have personally walked into on a Drones unit, not things I read about. Drone misbehaviour after a firmware update is real and frequent, I never push aircraft + remote firmware on the same day a flight is planned. Single-cell voltage divergence is the earliest warning a flight pack is failing; the app's percentage display is too coarse to catch it. When in doubt I revert to the slower path that the manual prescribes - the time I save by skipping it is always smaller than the time I spend cleaning up afterwards.

What I tell the next on-call

When I hand Holy Stone HS720G: Random restart off to the next person on rotation, the three lines I leave in the runbook are these. First, the symptom signature for Drones on the Drones family - not a paraphrase, the exact string that surfaces. Second, the diagnostic that gave the highest signal in the least time. Third, the exact verification command whose green output justified closing the ticket. That trio is what turns a one-off fix into a runbook entry the next engineer can use without paging me at three in the morning.

I also add a one-line note on the cost of getting this wrong. For Holy Stone HS720G: Random restart on a Drones unit, the cost is rarely the replacement part. It is the downtime, the second site visit, and the trust deficit you spend with whoever owns the asset when the fix does not hold. That framing keeps the next on-call from choosing the cheap-looking shortcut that ends up costing the most in elapsed hours and goodwill.
