Swipe Ace Strike Firmware Flash File Download [Stock Rom]

The Swipe Ace Strike (MT6735) was a 4G LTE variant of the popular budget model, but it was plagued by a critical connectivity flaw that rendered its key feature useless. As extensively documented on user forums like XDA-Developers, many owners reported that the “4G/LTE” network mode was completely absent or disabled in the mobile network settings, forcing the device to operate only on slower 2G and 3G networks. This issue, often accompanied by a failure to get a GPS lock and screen flickering at low brightness, was traced to incorrect modem configuration and faulty drivers. Flashing this official `RB_B4L3` stock firmware is the definitive solution, as it reinstalls the correct LTE band configuration and GPS libraries, fully enabling the device’s 4G and navigation capabilities.

Why Flash This Specific Firmware?

• Restore Missing 4G/LTE Network Mode: This is the primary and most critical reason for using this firmware. If your Ace Strike’s network settings lack the 4G/LTE option, flashing this `RB_B4L3` build reinstalls the complete modem firmware and NVRAM, which re-enables the LTE bands and makes the 4G option available again, as confirmed by user testimonials on technical forums.
• Fix GPS Lock Failure: Resolve the issue where navigation apps cannot get a location fix or take forever to do so. This firmware flash restores the original GPS configuration and AGPS data, ensuring fast and reliable satellite locking for accurate navigation.
• Eliminate Screen Flickering at Low Brightness: Address the annoying display flicker, especially in low-light conditions, by reinstalling the correct display driver and kernel modules responsible for smooth backlight control (PWM).
• Recover from Software Corruption or Bootloop: Unbrick your device if it has become unresponsive due to the modem configuration crash or other system file errors that can cause a bootloop.

Some of the Bug / Firmware Fixes

• Firmware Build RB_B4L3 (October 19, 2015): This version was specifically configured to enable the full set of LTE bands for the Indian market. It directly fixed the critical bug present in some regional firmware that completely hid the 4G/LTE preference in network settings.
• Updated the GPS chipset driver and configuration file (gps.conf) to significantly reduce the Time-To-First-Fix (TTFF), resolving the widespread GPS lock failure reported by users.
• Patched the kernel-level display driver to fix the Pulse-Width Modulation (PWM) control, eliminating the noticeable screen flickering at lower brightness levels.
• Improved general stability of the radio interface layer (RIL), reducing random signal drops and improving call clarity on both 3G and 4G VoLTE networks.

Crucial Prerequisites Before Flashing

• Backup All Data: The flashing process will completely wipe your phone’s internal memory.
• Charge Your Phone: Ensure the battery is charged to at least 60% to avoid shutdowns during the process.
• Install MediaTek VCOM Drivers: You must install the MediaTek USB VCOM drivers on your Windows PC.
• Download the Flashing Tool: You will need the SP Flash Tool.
• Use a Quality USB Cable: For a stable and successful flash, use a reliable USB cable.
