MyPhone MYA3 Stock Firmware Download (SP7731CEB Android 6.0)

The MyPhone MYA3 (SP7731CEB) was a popular budget Android 6.0 device in the Philippine market. According to multiple service technician reports on PHCorner forums and YouTube repair channels, this model frequently experiences unresponsive touchscreen issues and boot loops after software corruption — with the specific firmware version V1.09 (20170831) being cited as the most stable build that reliably resolves these hardware communication failures.

Why Flash This Specific Firmware?

• Touchscreen responsiveness restoration: Multiple technicians on PHCorner forums have documented cases where the MYA3 develops unresponsive touchscreen areas, particularly along the edges. As discussed in a 2018 thread, this is often caused by corrupted touch panel drivers that are properly reinstalled with the stock V1.09 firmware flash.
• Boot loop resolution after failed updates: Users on Filipino smartphone Facebook groups frequently report the MYA3 entering boot loops after interrupted OTA updates. Service center technicians confirm that the August 2017 build (V1.09) contains stable bootloader files that prevent these cyclic boot failures.
• Network signal and SIM detection fixes: Spreadtrum devices like the MYA3 are prone to baseband corruption that results in “No Service” errors. The stock firmware contains the original modem files that restore proper network registration and dual-SIM functionality.
• Battery calibration and charging issues: Several YouTube repair tutorials specifically mention the MYA3 having incorrect battery percentage readings and slow charging problems that are resolved by reflashing the factory firmware.
