About the Lenovo A6800
The Lenovo A6800 was released in May 2015, built on the 64-bit MediaTek MT6732 (28nm) platform. Featuring a 5.0-inch 720p HD IPS display, a 13 MP rear camera, and a removable 2150 mAh battery, the A6800 runs official Android 4.4.4 KitKat with Lenovo VIBE UI 2.0.
Flashing official stock firmware using MediaTek SP Flash Tool resolves bootloops, fixes corrupted system partitions, and restores factory software operation. Follow the verified bench steps below to flash your device safely.
Which Flash Mode Should You Use?
SP Flash Tool (Scatter Flashing Mode)
Official low-level flashing protocol for the Lenovo A6800. Writes partition blocks directly over MediaTek's BROM/Preloader interface using MT6732_Android_scatter.txt. Does not require an unlocked bootloader.
Android Stock Recovery Mode
Built-in recovery environment used for performing factory data resets, cache partition wipes, and ADB sideload packages.
What You Need Before Flashing
A PC running Windows with official MediaTek USB VCOM Preloader drivers installed.
Download and extract the official A6800 stock ROM containing MT6732_Android_scatter.txt.
Ensure the removable 2150 mAh BL242 battery has at least 40% charge prior to flashing.
Use a verified microUSB data cable connected directly to a rear USB 2.0 port.
Writing system and userdata partitions completely erases all personal data from the device.

Scatter File & Firmware Package for MT6732
The Lenovo A6800 stock firmware package unpacks to reveal MT6732_Android_scatter.txt along with raw partition binaries (preloader, boot.img, recovery.img, system.img, and cache.img). These map the exact partition boundaries of the 8 GB eMMC flash chip.
MT6732_Android_scatter.txt
Official factory firmware for the Lenovo A6800 utilizes MT6732_Android_scatter.txt to map the partition table. In SP Flash Tool, click "Choose" next to Scatter-loading File and select MT6732_Android_scatter.txt from the extracted firmware folder.
The Lenovo A6800 utilizes the MediaTek MT6732 quad-core 64-bit processor paired with 1 GB RAM. Always use the "Download Only" or "Firmware Upgrade" mode within SP Flash Tool. Selecting "Format All + Download" wipes the protected NVRAM partition, destroying cellular baseband calibration.

Lenovo A6800 — Important Notes
The removable 2150 mAh BL242 battery makes bench servicing straightforward on the Lenovo A6800. If the device fails to establish a stable Preloader handshake in Windows Device Manager, remove the battery for 10 seconds, reseat it firmly, and reconnect the USB cable while holding Volume Down.
Troubleshooting Lenovo A6800 MediaTek MT6732 & SP Flash Tool Flashing Issues
SP Flash Tool: BROM ERROR : S_FT_ENABLE_DRAM_FAIL (4032)
The Preloader handshake failed to initialize the LPDDR3 RAM controller on the MT6732 SoC. Community repair discussions indicate this is typically triggered by connecting over modern USB 3.0 ports, unverified charging-only cables, or residual controller charge. Pull the BL242 battery for 10 seconds, switch to a rear motherboard USB 2.0 port, and verify that MT6732_Android_scatter.txt is loaded.
SP Flash Tool: PMT CHANGED FOR THE ROM (8038)
Occurs when the eMMC partition table on the phone does not match the partition addresses defined in the scatter file. Technicians advise changing the flashing dropdown from "Download Only" to "Firmware Upgrade" so SP Flash Tool can safely sync the partition table without wiping radio calibration data.
Phone enters Meta Mode or Fastboot instead of Preloader flashing
Holding the Volume Up key or both volume keys during USB insertion can trigger MediaTek Meta Mode (yellow text on black screen) or Fastboot mode. Community repair technicians suggest holding only the Volume Down button (or inserting the cable with the phone powered off and battery reseated without holding any buttons) to engage the Preloader COM port.

Frequently Asked Questions — Lenovo A6800
MediaTek MT6732 devices communicate via a short 2 to 3-second Preloader window when connected via USB while powered off. If your PC does not recognize the phone, pull the removable 2150 mAh BL242 battery for 10 seconds to discharge the PMIC. Reinsert the battery, click "Download" in SP Flash Tool first, and connect the USB cable while holding Volume Down. Ensure you are using a direct motherboard USB 2.0 port rather than a front-panel USB 3.0 port.
Error 8038 indicates that the partition layout currently stored on the phone's eMMC chip differs from the layout in MT6732_Android_scatter.txt (frequent when moving between factory builds). In SP Flash Tool, change the dropdown menu from "Download Only" to "Firmware Upgrade". This instructs the tool to safely rebuild the partition map without touching the protected NVRAM partition.
If the device hangs on the Lenovo startup screen after flashing, remove the battery to power it off completely. Reinsert the battery, then press and hold Volume Up, Volume Down, and the Power key simultaneously until the recovery boot menu appears. Use the volume keys to highlight "Recovery Mode" and press Power to enter. From there, select "wipe data/factory reset" and "wipe cache partition".
Always select "Download Only" or "Firmware Upgrade" in SP Flash Tool. Never click "Format All + Download", because that option formats the physical eMMC storage partitions, erasing the NVRAM and NVDATA sectors where the unique dual IMEI addresses and radio calibration data are stored.
