The Homtom HT3 Pro (MT6735M) is a budget 5.0‑inch smartphone from the 2015‑2016 era, featuring a MediaTek MT6735 quad‑core processor, 2 GB RAM, and 16 GB storage running Android 5.1 Lollipop in its factory state.
Common software issues on this older model include bootloops after failed root attempts, corrupted storage from full 16 GB capacity, and instability from unofficial updates or low‑RAM multitasking overload.
Installing the original stock firmware via SP Flash Tool can help restore factory software integrity, repair partition corruption, and return the phone to a stable baseline, though success varies based on the specific fault and hardware condition.

⚠️ Flashing Risks & Disclaimer
Flashing this MT6735M phone with SP Flash Tool accesses the eMMC storage directly, posing risks heightened by the device’s older architecture and limited 16 GB storage, where partition overflows or incomplete writes are more common. Selecting an incorrect scatter file or using “Format All + Download” without NVRAM preservation can wipe IMEI, modem data, and calibration settings, rendering the device unable to connect to networks or boot properly. Interruptions during the preloader or boot partition transfer, often from cheap USB cables or power fluctuations, can result in a hard brick requiring specialized hardware recovery.

Flashing Requirements
- PC & OS: Windows PC (7/8/10/11) with admin privileges, stable USB connection, and 2+ GB free space for extraction and tool operation.
- Drivers & Tools: MediaTek VCOM / USB drivers and SP Flash Tool v5.x compatible with MT6735M scatter files.
- Bootloader Status: Stock firmware flashes work on the default locked bootloader for Homtom MTK devices; no additional unlock is typically required.
- Backup Advice: Back up all user data and NVRAM/IMEI before proceeding, as certain flash modes may erase apps, media, and network settings on this limited‑storage model.
- Hardware Verification: Ensure the device is the Homtom HT3 Pro with MT6735M (check build info or label); do not use on standard HT3 or MT6735 variants with mismatched partitions.
How to Flash the Firmware
- Download and extract the Homtom_HT3_Pro_MT6735M_20161105_1.0.5.zip to access the scatter file and images for the MT6735M platform in SP Flash Tool.
- Install MediaTek USB drivers, open SP Flash Tool, load the scatter file from the extracted folder, and verify that partitions like preloader, boot, and system are selected correctly for the HT3 Pro.
- Choose “Download Only” for a non‑destructive restore or “Firmware Upgrade” if switching builds, avoiding “Format All + Download” unless NVRAM is backed up to prevent IMEI loss.
- Power off the phone, connect via USB while the tool is ready, and let SP Flash Tool handle the transfer until the green success indicator appears.
- Disconnect, power on the HT3 Pro, and expect a longer initial Android 5.1 boot as the system optimizes; test basics like calls, Wi‑Fi, and storage before data restoration.

Frequently Asked Questions (FAQs)
Is this firmware for HT3 Pro or the standard HT3?
This package targets the Homtom HT3 Pro with MT6735M specifically and should not be flashed on the base HT3 model, which has different firmware and partition structures.
Can flashing resolve issues from rooting or custom ROMs on this device?
A full stock flash of the correct HT3 Pro ROM can often recover from root failures, custom recovery bootloops, or partition corruption by overwriting the modified system areas with factory images, but it requires the exact MT6735M scatter file.
Will IMEI be erased during the flash process?
Safer modes like “Download Only” preserve IMEI and modem data, but “Format All + Download” or modem partition flashes can clear NVRAM, necessitating IMEI restoration tools afterward on MT6735M devices.
Does this update Android from 5.1 to a higher version?
No, this restores the official Android 5.1 Lollipop build for the HT3 Pro and does not upgrade to Android 6.0 or later; it is a stock revert package.
Is bootloader unlocking necessary for SP Flash Tool on the HT3 Pro?
SP Flash Tool bypasses the user bootloader via preloader mode on MediaTek phones like this one, so no unlocking is needed for stock firmware restoration, though it may affect warranty claims.
Why is the storage so limited after flashing (around 10 GB usable)?
The HT3 Pro has 16 GB total eMMC with a fixed system partition allocation, leaving limited user space; flashing does not expand hardware capacity, but a clean install can free up space lost to corruption.
What SP Flash Tool errors are typical for MT6735M on this model?
Common issues include preloader handshake failures from outdated drivers, BROM errors on USB disconnects, or DRAM mismatches if the wrong scatter is loaded, so double‑check firmware compatibility and cable stability.
Can this firmware fix camera or sensor problems?
It can resolve software‑related camera or sensor glitches from corrupted drivers after updates, but hardware faults like faulty IMX219 modules or loose connections require physical repair.
