DJI Fly 앱 중국 버전은 어떤 고도 제한을 적용합니까?

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.

암호 재정의 해결 방법은 실제로 어떻게 작동합니까?

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.

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.

재정의 실패 후 벽돌이 된 드론을 수리하는 데 비용이 얼마나 드나요?

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.

어떤 DJI 드론 모델이 고도 제한이 있는 중국 전용 버전으로 제공됩니까?

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.

왜 Reboot Hub에서 구매해야 하나요?

Every drone sold by Reboot Hub is a genuine international‑version unit, free from China firmware altitude restrictions, and hand‑inspected to our 40‑point checklist. We source only activation‑only Flawless A+ or minimal‑use Pristine Pre‑Owned A grade aircraft — never refurbished, never rebuilt. Each drone is disassembled, cleaned, and reassembled using genuine OEM parts; our Shenzhen technicians hold MOHRSS Level 3 certifications, the highest available for drone electronics repair in China.

It’s the only way to enjoy unrestricted flight with total peace of mind.

자주 묻는 질문

Q: 중국에서는 DJI 드론에 고도 무시 비밀번호를 사용하는 것이 합법적인가요?

A: 아니요. CAAC의 공식 허가 없이 120미터 고도 제한을 우회하는 것은 불법입니다. 비밀번호를 무단으로 사용하면 5,000~100,000엔(690~13,800달러)의 벌금이 부과되고 드론이 압수될 수 있습니다. DJI는 ​​또한 비행 기록을 당국과 공유하므로 위반 사항이 거의 항상 발견됩니다. 유일한 합법적인 경로는 DJI의 공식 프로세스를 통해 임시 잠금 해제를 요청하는 것입니다. 이를 위해서는 유효한 프로젝트 문서가 필요하며 소비자에게 거의 부여되지 않습니다. 국제 버전 드론을 구입하면 재정의가 필요 없으며 규정을 준수할 수 있습니다.

Q: 고도 제한을 제거하기 위해 중국 버전 드론을 국제 펌웨어로 변환할 수 있나요?

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.

Q: DJI가 승인되지 않은 고도 오버라이드를 감지하면 어떻게 됩니까?

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.

Q: 중고 드론이 제한 사항이 있는 중국 버전인지 어떻게 알 수 있나요?

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.

Q: Reboot Hub의 벽돌 드론 수리 서비스는 얼마나 걸리나요?

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.

질문: Reboot Hub에서 Flawless A+ 등급과 Pristine Pre-Owned A 등급의 차이점은 무엇입니까?

A: Flawless(A+) 드론은 활성화 전용 장치입니다. 원래 소유자가 드론의 포장을 풀고 활성화했지만 비행한 적이 없으므로 비행 시간이 전혀 없고 전혀 마모되지 않습니다. 깨끗한 중고(A) 드론은 일반적으로 5시간 미만으로 최소한으로 비행했으며 확대하여도 눈에 띄는 흔적이 보이지 않습니다. 두 등급 모두 동일한 40개 지점 검사를 거치며 180일 보증이 포함됩니다. 가격 차이는 약 8%입니다. 예를 들어 Pristine DJI Mini 4 Pro는 Flawless A+ 가격 $639에 비해 $50를 절약합니다.

Q: Reboot Hub 드론에는 고도 제한이 없는 국제 버전의 DJI Fly가 함께 제공됩니까?

A: 예, 우리가 판매하는 모든 드론은 무제한 DJI Fly 앱을 실행하는 정품 국제 버전 모델입니다. 페어링 시 앱은 500미터의 표준 고도 한도를 허용합니다(현지 규정에 따라 - 여전히 해당 국가의 법적 제한을 준수해야 함). 비밀번호 프롬프트도 없고, 숨겨진 메뉴도 없으며, 120m까지 잠길 위험도 없습니다. 40개 항목을 검사하는 동안 각 장치의 펌웨어 지역을 확인하므로 상자에서 꺼내자마자 하드웨어 기능을 완벽하게 활용할 수 있는 드론을 받았다는 확신을 가질 수 있습니다.
