The Mobiistar XQ Dual is a budget dual‑camera phone powered by the Qualcomm Snapdragon 430 octa‑core chipset with a 5.5‑inch Full HD display and 3 GB RAM / 32 GB storage configuration.
On this model, heavy multitasking with limited RAM, failed OTA attempts, and storage exhaustion from apps can cause bootloops, performance drops, or soft‑bricks after modifications, and flashing the factory CPB package like 7.0.042.P1.180509 can help restore the device to a clean Android 7.1.2 baseline.

Flashing Requirements
- A Windows PC (Windows 7 or newer) with administrator privileges.
- Qualcomm HS‑USB QDLoader 9008 drivers installed so the device enters EDL (Emergency Download) mode correctly.
- YGDP Tool (Qualcomm Download Program) downloaded and extracted to a local folder.
- The full Mobiistar_XQ_Dual_7.0.042.P1.180509_7.0_CPB.zip downloaded and ready for YGDP configuration.
- A genuine Mobiistar XQ Dual phone with Snapdragon 430 chipset, confirmed via Settings > About phone or hardware specs before flashing.
- Battery charge above 40% to prevent interruptions during the flashing process.
- Full backup of user data, as YGDP flashing this CPB package typically performs a complete wipe of system and user partitions.
- High‑quality USB cable and a direct PC USB port for stable EDL connection.
How to Flash the Firmware
- Download the Mobiistar_XQ_Dual_7.0.042.P1.180509_7.0_CPB.zip firmware package for the Mobiistar XQ Dual and ensure it is accessible in a simple folder path without spaces.
- Install Qualcomm HS‑USB drivers, launch YGDP Tool, enter the password (often 369 if prompted), then click the Config button and load the CPB file from the extracted archive.
- Power off the XQ Dual completely, then hold the Volume Up key (or test point for EDL if needed) while connecting it to the PC via USB to enter EDL mode; YGDP should detect the Snapdragon 430 port.
- Click Start in YGDP to begin flashing the 7.0.042.P1.180509 firmware; monitor the progress bar and do not disconnect until the tool reports a successful completion.
- Disconnect the USB cable and power on the device; the first boot into Android 7.1.2 Nougat after a CPB flash may take longer as the system partitions are reformatted and initialized.

Frequently Asked Questions (FAQs)
Is this CPB firmware specific to the Snapdragon 430 Mobiistar XQ Dual?
Yes. The 7.0.042.P1.180509 package is built for the Mobiistar XQ Dual’s Qualcomm Snapdragon 430 (MSM8937) chipset and should only be used on matching hardware to prevent partition or modem damage.
Can this ROM be used to downgrade from a later Android version?
Downgrading via YGDP CPB flashing is possible if the bootloader allows it, but it carries a higher risk of bricking on Snapdragon 430 devices due to binary revision checks; use only for recovery to stock Android 7.1.2.
Does flashing CPB firmware affect the fingerprint sensor or dual cameras?
Stock CPB ROMs for the XQ Dual include the factory calibration for the fingerprint sensor and dual front cameras, so flashing should restore full functionality if software corruption was the issue.
Will this erase data on the 32 GB storage?
YGDP flashing with this CPB package typically wipes the userdata partition completely, making it a clean install; back up photos and apps beforehand as recovery after flashing is not guaranteed.
How to enter EDL mode if the phone is soft‑bricked?
For a soft‑bricked Mobiistar XQ Dual, use the Volume Up + Power while connecting USB, or short the test points on the motherboard for forced EDL entry before running YGDP Tool.
Can this firmware fix lag from multitasking on 3 GB RAM?
If lag stems from corrupted system caches or bloatware buildup, flashing the clean 7.0.042.P1.180509 stock ROM can improve baseline performance, though hardware limits on the Snapdragon 430 and 3 GB RAM remain.
Does it support VoLTE after flashing this Indian build?
This firmware retains VoLTE and 4G LTE support for Indian carriers as per the XQ Dual’s original configuration, but carrier‑specific provisioning may need re‑activation post‑flash.
