The HDC i6S Plus is an iPhone-style Android smartphone built on the MediaTek MT6582 platform, distributed with Android KitKat derivatives and later Lollipop-based builds for certain revisions. Users of this device frequently encounter software-related faults such as bootloops after unsuccessful modifications, soft-bricks due to incompatible ROMs, or instability following experimental “iOS-style” theme updates. Installing the correct Android 5.0 MT6582 firmware can help return the phone to a clean, bootable state and provide a stable base for further servicing or resale, without guaranteeing resolution of every individual issue.

⚠️ Flashing Risks & Disclaimer
Because the HDC i6S Plus uses the MediaTek MT6582 platform with clone-specific preloader and modem layouts, flashing the wrong scatter package can result in a fully dead device that no longer responds over USB or shows any sign of charging. In addition, mismatched firmware may overwrite baseband and NVRAM partitions, potentially causing loss of IMEI, permanent “No service” behaviour, or unstable cellular connectivity even if Android boots.
The Android 5.0 MT6582 firmware listed below is intended only for compatible HDC i6S Plus boards and should not be cross-flashed to other MT6582 “iPhone” clones or to HDC 6S / i6 / i6S non‑Plus models. Before attempting any operation with SP Flash Tool, users should ensure adequate backups of NVRAM and user data, and accept that all flashing is carried out entirely at their own risk.

The Android 5.0 package above is commonly referenced in servicing forums and firmware collections under the name “HDC_i6S_Plus_MT6582_04032016_5.0” and is specifically tagged for MT6582 hardware in multiple sources.
Flashing Requirements
- Operating system: A Windows PC (Windows 7, 8, 8.1, 10, or newer) with rights to install unsigned USB drivers and run SP Flash Tool.
- MediaTek drivers: Mediatek VCOM / Preloader USB drivers suitable for MT6582 devices so the HDC i6S Plus is detected in preloader Download mode.
- Main flashing utility: A compatible SP Flash Tool v5.x release that correctly handles MT6582 scatter files and can communicate with the clone’s preloader.
- Firmware package: The exact archive appropriate for this model, such as
HDC_i6S_Plus_MT6582_04032016_5.0.zipextracted to a dedicated folder containing the MT6582 scatter file and images. - Bootloader / mode: Standard MTK preloader “Download” mode (device powered off and detected briefly as a MediaTek preloader port); no fastboot or OEM unlock is used on this clone family.
- Backups: If possible, a full backup of:
- User data (contacts, app data, media) from the running system, since a clean flash may wipe the data partition.
- NVRAM / NVDATA and IMEI using MTK tools or SP Flash Tool readback, to mitigate network issues if NVRAM is overwritten.
- Verification of device compatibility: Confirm that the phone is an HDC i6S Plus MT6582 (not HDC 6S, not i6S non‑Plus, and not a different MT6580/MT6753 iPhone-style clone) by checking board information and SoC details where possible.
- Power and cabling: Battery charged to at least 50% and a stable USB connection (no loose ports, avoid unpowered hubs) to reduce the risk of transfer failures during flashing.
How to Flash the Firmware
- Download and extract the correct MT6582 package. Obtain the HDC i6S Plus Android 5.0 archive and extract it to a folder on the PC; confirm that a scatter file for MT6582 (such as
MT6582_Android_scatter.txt) and the associated partition images (system.img,boot.img, etc.) are present. - Install Mediatek drivers and prepare SP Flash Tool. Install the Mediatek Driver package compatible with SP Flash Tool usage on HDC “iPhone” devices, then download and unpack a suitable SP Flash Tool v5.x build and start
flash_tool.exeon the Windows machine. - Load the HDC i6S Plus scatter and configure the flash mode. In SP Flash Tool’s “Download” tab, click “Scatter-loading” and select the MT6582 scatter from the extracted firmware; after the partition list loads, choose “Download Only” for typical recovery on this model or “Firmware Upgrade” only when a full layout refresh is necessary and complete backups are available.
- Connect the powered-off phone in preloader mode and start flashing. With the HDC i6S Plus completely powered off, click the green “Download” button in SP Flash Tool and then connect the device by USB; a sequence of progress bars should appear until a green success circle indicates that the Android 5.0 firmware has been written.
- Boot into Android 5.0 and verify basic functions. Disconnect the cable, power on the phone, and allow extra time for the first Lollipop boot on this MT6582 clone; once the setup screen appears, check IMEI, baseband status, and basic functions (calling, Wi‑Fi, touchscreen) before restoring user data or making further modifications.

Frequently Asked Questions (FAQs)
Is this Android 5.0 firmware compatible with all HDC i6S Plus units?
The 04032016 5.0 package is intended for HDC i6S Plus units built on the MT6582 platform; some clones share similar branding but use different chipsets or layouts, so flashing must be limited to verified MT6582 boards from the same family.
Can the Android 5.0 package be flashed over the older 4.4 build?
Yes, SP Flash Tool can write the 5.0 system over a previous 4.4 firmware for this device, but the operation behaves as a full firmware replacement rather than an incremental OTA, so user data may be erased depending on which partitions are selected.
What happens if a different MT6582 “iPhone” ROM is used?
Using a scatter package made for another MT6582 “iPhone” clone (for example, firmware tagged for a different Apple-style model) can introduce preloader or modem mismatches, which may leave the phone non‑booting or without network service even if it powers on.
Will this firmware restore IMEI on an HDC i6S Plus?
The Android 5.0 ROM can restore system and boot partitions but cannot recreate a lost IMEI if NVRAM or NVDATA were previously damaged; separate IMEI or NVRAM repair files are needed for network calibration in such cases.
Does flashing with SP Flash Tool require an unlocked bootloader on this model?
On the HDC i6S Plus, SP Flash Tool communicates directly with the MT6582 preloader and does not use a standard fastboot OEM-unlock process, but it bypasses most user-facing protections, so misuse can still lead to permanent damage.
Is it possible to downgrade from Android 5.0 back to 4.4?
Downgrading is possible by flashing the earlier HDC i6S Plus 4.4 package with SP Flash Tool, provided that the MT6582 board revision matches; however, the process should again be treated as a full reinstall with appropriate backups.
What typical SP Flash Tool errors appear with this phone?
MT6582 devices often show preloader handshake or BROM errors if drivers are not installed correctly, and scatter mismatch messages can occur when a firmware package for a different MTK project or board configuration is selected.
