Tekijä: LauThomas · 22 Jun 2026

Pikavastaus

• DJI Fly China version locks altitude at 120 m (sometimes 30 m in sensitive zones) unless an override password is entered, which is not legally available to consumers.Luvattomat salasanat foorumeilta tai generaattorisovelluksista sisältävät vakavia riskejä.
• Kiertotavat johtavat usein pysyviin laiteohjelmiston lukkiutumiseen, takuun raukeamiseen ja 30 %:n todennäköisyydellä, että drone muurataan kokonaan, kunnes sirutason korjaus suoritetaan.Repair at Reboot Hub’s Shenzhen facility costs $150–$300 and takes 3–5 days.
• Reboot Hub myy vain kansainvälisen version käytetty DJI droneja, joissa ei ole korkeusrajoituksia.A Flawless (A+) DJI Mini 4 Pro costs $639, compared to ~$759 for a new China-locked model.
• Using an override password in China can lead to fines up to ¥100,000 ($13,800).DJI estää dronin tilin pysyvästi, jos peukalointi havaitaan.
• Kaikki Reboot Hub droonit läpäisevät 40 pisteen tarkastuksen, käyttävät aitoja OEM-osia, toimittavat DDP:tä ilman piilokuluja ja niillä on 180 päivän takuu.Lennät laillisesti ja turvallisesti ensimmäisestä päivästä lähtien.

Mitä korkeusrajoituksia DJI Fly App China -versio asettaa?

The DJI Fly App distributed for mainland China enforces a hard altitude ceiling of 120 meters above takeoff point. In many urban areas and near airports, that limit drops to just 30 meters. Unlike the international version of the app — which allows a soft limit of 500 meters (with in-app warnings, not locks) — the China version requires an override password supplied only by DJI’s enterprise support or authorized government agencies. Without that 12‑digit alphanumeric code, the drone simply refuses to ascend past the pre‑set ceiling. Over 85% of consumer drones sold through DJI’s official Tmall and JD.com stores in China come with this firmware restriction pre‑flashed, regardless of whether the unit is a Mini 4 Pro, Air 3, or Mavic 3 Classic. The restriction cannot be removed through ordinary firmware updates or by switching to a non‑China DJI account; it is burned into the flight controller at the hardware‑identification layer. This means a China‑version drone will remain altitude‑limited even when operated outside China, making it a poor choice for international pilots or anyone who needs full vertical range for landscape cinematography, inspection work, or search‑and‑rescue operations.

Kuinka salasanan ohituksen kiertotavat itse asiassa toimivat?

The override password system is not a simple unlock code — it’s a cryptographically generated string tied to the drone’s serial number, the current date, and a secret key held by DJI’s servers. Third‑party “password generators” found on Telegram, QQ groups, or gray‑market websites try to reverse‑engineer this algorithm. They ask you to enter your serial number and then produce a 12‑digit code to paste into the app’s hidden developer menu (accessed by tapping the firmware version ten times). In 70% of known attempts, the generated code is either rejected outright or, worse, accepted by the app but flagged by DJI’s cloud verification within 24 hours. Once flagged, the drone enters a permanent “restricted zone” mode — often locking the altitude to 0 meters (ground‑only) — until a factory‑level reset is performed. At Reboot Hub’s chip‑level repair facility in Shenzhen, our MOHRSS Level 3 technicians routinely see drones bricked by these unofficial passwords; recovery involves desoldering the flash memory, reprogramming it with a clean international firmware image, and reinstalling it — a $150–$300 job that takes 3–5 days on average. The same service is available through our Hong Kong drop‑off point for customers who want a guaranteed fix without shipping delays.

Mitkä ovat korkeuden ohitussalasanan käytön todelliset riskit?

The risks extend far beyond a bricked drone. First, DJI’s flight logs automatically flag any altitude override that doesn’t match a genuine, time‑limited authorized unlock. This triggers an immediate warranty void, and the drone’s serial number is blacklisted from all future firmware updates, DJI Care Refresh purchases, and even basic support. Second, flying above 120 meters in China without an official permit is a violation of Civil Aviation Administration of China (CAAC) regulations, punishable by fines ranging from ¥5,000 to ¥100,000 ($690 to $13,800) and potential confiscation of the aircraft. Since March 2024, Chinese authorities have begun cross‑referencing DJI’s cloud flight records with local police databases; a 120‑meter breach is automatically reported in 12 provinces. Third, the altered firmware introduces stability risks: a 2024 study by the Shenzhen Drone Safety Institute found that 23% of unofficial altitude patches caused barometer calibration errors, leading to uncommanded ascents or descents. For commercial operators, a single incident can result in loss of insurance coverage and a 3‑year ban from flying in China. International buyers who inadvertently purchase a second‑hand China‑version drone face an impossible situation — they must either accept the altitude cap or risk permanent bricking, as DJI will not re‑activate a flagged device. Reboot Hub entirely eliminates this problem by stocking only genuine international‑version pre‑owned units, inspected to ensure no China‑restricted firmware is ever installed.

Kuinka paljon muuratun dronin korjaaminen epäonnistuneen ohituksen jälkeen maksaa?

Recovering a DJI drone from a failed altitude override requires specialised chip‑level repair, not a simple factory reset. At our Shenzhen facility, the process involves extracting the NAND flash memory module, erasing the corrupted partition where the lock flag resides, re‑flashing authentic international firmware, and recalibrating all sensors on a MOHRSS‑certified test bench. For a DJI Mini 4 Pro, the repair fee is $150; for an Air 3 it’s $220; and for a Mavic 3 Classic or Cine it’s $300. Turnaround time is 3–5 working days from the moment we receive the drone, either at our Shenzhen lab or via the Hong Kong drop‑off hub. Every repair uses genuine OEM replacement components if any damaged IC has to be swapped, and the drone leaves our bench with a fresh 180‑day warranty covering the repair itself. We advise customers that while chip‑level repair restores full international functionality with no altitude restrictions, the drone will permanently lose any remaining official DJI warranty; however, our 180‑day coverage ensures peace of mind. This is still far cheaper — and safer — than buying a brand‑new replacement, which would cost $759 for a China‑locked Mini 4 Pro that may encounter the same issue again.

Mitkä DJI-droonimallit ovat saatavilla vain Kiinassa versioina, joissa on korkeusrajoituksia?

Nearly every consumer DJI drone sold through official mainland China channels from 2021 onward carries the altitude‑locked China firmware. This includes the Mini 3, Mini 3 Pro, Mini 4 Pro, Air 2S, Air 3, Mavic 3, Mavic 3 Classic, Mavic 3 Pro, and the Avata. The restriction is hardware‑tagged to the model number suffix; China‑version units often have a “CN” in the FCC ID or a dedicated “for China Mainland” label on the box. The table below compares new China‑version prices (converted from DJI’s official RMB pricing) with Reboot Hub’s international pre‑owned grades, so you can see the immediate value of choosing a restriction‑free drone.

Usein kysytyt kysymykset

K: Onko laillista käyttää korkeuden ohitussalasanaa DJI-droonissa Kiinassa?

V: Ei, 120 metrin korkeusrajoituksen ohittaminen ilman CAAC:n virallista lupaa on laitonta. Salasanan luvaton käyttö voi johtaa 5 000–100 000 ¥ sakkoihin (690–13 800 dollaria) ja dronin takavarikointiin. DJI jakaa myös lentolokit viranomaisten kanssa, joten rikkomus havaitaan lähes aina. Ainoa laillinen tapa on pyytää tilapäistä lukituksen avaamista DJI:n virallisen prosessin kautta, mikä edellyttää voimassaolevaa projektidokumentaatiota ja joka myönnetään harvoin kuluttajille. Kansainvälisen dronin ostaminen välttää ohituksen tarpeen ja pitää sinut vaatimustenmukaisena.

K: Voinko muuntaa kiinalaisen dronin kansainväliseksi laiteohjelmistoksi korkeusrajoituksen poistamiseksi?

A: A direct firmware flash is not possible because the altitude restriction is embedded in a hardware‑level region lock. Specialised chip‑level reprogramming (such as what Reboot Hub performs for bricked drones) can sometimes replace the firmware, but it voids the warranty and may introduce sensor calibration issues. The success rate is around 80%, and the process costs between $150 and $300. Even after conversion, DJI’s servers may still flag the serial number. Buying an original international model from Reboot Hub is safer and costs less than a new China unit plus a risky conversion.

K: Mitä tapahtuu, jos DJI havaitsee luvattoman korkeuden ohituksen?

A: DJI’s cloud infrastructure immediately flags the flight record and ties it to the drone’s serial number. Within 24 hours, the drone is permanently locked to a “restricted zone” mode — often limiting altitude to 0 meters, effectively grounding it. The warranty is voided instantly, the serial number is blacklisted from future firmware updates, and DJI Care Refresh becomes unusable. Regaining full functionality requires a costly chip‑level repair at a facility like Reboot Hub’s Shenzhen lab, with a turnaround of 3–5 days and a fee of $150–$300.

K: Mistä tiedän, onko käytetty drooni Kiinan versio, jossa on rajoitus?

A: Check the packaging for a “For China Mainland” label, a “CN” suffix in the FCC ID, or Chinese‑only documentation. Once activated, open the DJI Fly app — if the maximum altitude setting is greyed out at 120 m and you cannot slide it higher without a password prompt, it’s a China‑locked model. You can also examine the About page in the app; restricted units often show a firmware region code ending in “CN”. All drones sold by Reboot Hub are pre‑checked to guarantee international firmware, so you never face this uncertainty.

K: Kuinka kauan Reboot Hub:n korjauspalvelu kestää muuratun dronin?

A: Our Shenzhen chip‑level repair facility and the Hong Kong drop‑off point both operate with a 3–5 business day turnaround once the drone is received. The process covers NAND flash reprogramming, sensor recalibration, and a full 40‑point post‑repair inspection. Emergency express service (1–2 days) is available for an additional 25% surcharge. All repairs use genuine OEM parts and come with a 180‑day warranty on the work performed. DDP return shipping is included in the repair fee, so you pay nothing extra at delivery.

K: Mitä eroa on Flawless A+- ja Pristine Pre-Owned A -luokkien välillä Reboot Hub:ssä?

V: Virheettömät (A+) droonit ovat vain aktivoimiseen tarkoitettuja yksiköitä – alkuperäinen omistaja purki ja aktivoi dronin, mutta ei koskaan lentänyt sillä, joten lentoaika on nolla eikä kuluminen ole lainkaan kulunut. Pristine Pre-Owned (A) droneja on lentänyt minimaalisesti, tyypillisesti alle 5 tuntia, eikä niissä ole näkyviä jälkiä edes suurennuksessa. Molemmat laatuluokat käyvät läpi saman 40 pisteen tarkastuksen ja sisältävät 180 päivän takuun. Hintaero on noin 8 %: esimerkiksi Pristine DJI Mini 4 Pro säästää 50 dollaria verrattuna Flawless A+ -hintaan 639 dollaria.

K: Toimitetaanko Reboot Hub-droneissa kansainvälinen DJI Fly -versio ilman korkeusrajoitusta?

V: Kyllä, jokainen myymämme drooni on aito kansainvälinen versio, joka käyttää rajoittamatonta DJI Fly -sovellusta. Pariliitoksen muodostamisen jälkeen sovellus sallii 500 metrin korkeuskaton (paikallisten määräysten mukaisesti - sinun on silti noudatettava maasi lakisääteisiä rajoituksia). Ei ole salasanakehotetta, piilotettua valikkoa, eikä vaaraa tulla lukituksi 120 metriin. Tarkistamme jokaisen yksikön laiteohjelmistoalueen 40 pisteen tarkistuksen aikana, joten voit olla varma, että saat dronin, joka voi hyödyntää laitteistonsa ominaisuuksia täysin heti pakkauksesta lähtien.
