The WE B2 is a 5.0-inch Bangladeshi budget smartphone featuring a MediaTek MT6735 quad-core processor, 3 GB RAM, up to 32 GB storage, dual SIM, 4G connectivity, and a large 4000 mAh battery for all-day use. Over time, many WE B2 and MT6735 users experience common issues such as random reboots, constant bootloops after failed updates or rooting, severe lag, app crashes, network instability, and soft-bricked devices that no longer boot into Android.
The We_B2_MT6735_6.0_KAAE1_BGK_1.00_729.zip stock firmware is an official, scatter-based Android 6.0 ROM designed to fully restore the WE B2, fix bootloops, resolve serious software corruption, and bring the phone back to a clean, stable factory state when flashed correctly with SP Flash Tool.

Flashing Requirements
- WE B2 smartphone with confirmed MT6735 chipset, at least 60% battery, and original or good‑quality USB cable for a stable connection.
- We_B2_MT6735_6.0_KAAE1_BGK_1.00_729.zip extracted on a Windows PC, revealing the MT6735 scatter file and partition images (system, boot, recovery, etc.).
- Latest SP Flash Tool compatible with MT6735, plus properly installed MediaTek VCOM/Preloader USB drivers.
- Full backup of personal data, and if possible, a backup of NVRAM/IMEI using MTK engineering or backup tools before flashing.
- Basic understanding of SP Flash Tool options (Download Only vs Firmware Upgrade) and awareness that flashing preloader carries additional risk.
How to Flash the Firmware
- Install MTK VCOM/Preloader drivers on your PC, then extract both SP Flash Tool and the We_B2_MT6735_6.0_KAAE1_BGK_1.00_729.zip firmware into separate folders.
- Run SP Flash Tool, click “Scatter-loading,” and select the MT6735_Android_scatter.txt file from the WE B2 firmware folder to load all partitions.
- Choose “Download Only” for a standard reinstall or “Firmware Upgrade” for deeper repair, carefully decide whether to include preloader, and then press the green Download button.
- Turn off the WE B2, connect it to the PC via USB (you may need to hold a volume key), and wait while SP Flash Tool flashes the firmware until you see the green success checkmark.
- Disconnect the phone and power it on; the first boot into Android 6.0 may take several minutes while the system optimizes apps and completes initial setup.

Frequently Asked Questions (FAQs)
What problems can this WE B2 firmware fix?
The WE B2 MT6735 stock ROM can repair bootloops, stuck-on-logo errors, severe lag, repeated app or system crashes, and software damage from failed rooting, malware, or experimental ROMs. It is also useful for soft‑bricked devices that still connect to a PC in preloader mode but cannot boot into Android.
Is this firmware only for the WE B2 with MT6735?
Yes, the We_B2_MT6735_6.0_KAAE1_BGK_1.00_729.zip build is tailored specifically for the WE B2 model with MT6735 hardware and Android 6.0; flashing it on other WE models or different chipsets can instantly hard‑brick those phones. Always verify the exact model name and chipset before flashing any ROM.
Will this firmware upgrade Android beyond Marshmallow?
No, this package keeps the WE B2 on Android 6.0 Marshmallow and focuses on stability, security, and bug fixes rather than major OS upgrades. Users wanting newer Android versions would need custom ROMs, which carry additional compatibility and reliability risks.
SP Flash Tool does not detect my WE B2. What should I do?
Reinstall VCOM drivers, use a different USB port and cable, ensure the phone is completely powered off, and try holding Volume Up or Down while connecting to help trigger preloader mode. Also avoid USB hubs and make sure no other MTK tools are running in the background.
