The Mobiistar CQ is an entry-level Android 7.0 Nougat smartphone commonly featuring a MediaTek chipset, used as a budget device for basic communication and light tasks. This model often encounters software issues such as bootloops after failed updates, OTA corruption during low-storage conditions, or devices stuck on the logo following root or system tweaks. Flashing the appropriate stock CPB firmware package can help recover the phone by restoring original partitions and resolving these faults, without addressing hardware limitations.
This page lists two preserved stock CPB ROM builds for the Mobiistar CQ, designed for Qualcomm-compatible flashing tools like QGDP or QPST. The packages are mirrored from Google Drive and intended for users experienced with CPB firmware handling.

⚠️ Flashing Risks & Disclaimer
Flashing Mobiistar CQ CPB firmware with mismatched tools or interrupted writes can result in a hard brick, permanent IMEI loss, or modem failure. CPB packages contain sensitive modem and NV partitions; using the wrong build or tool can corrupt radio calibration, leading to no signal or unstable connectivity that is hard to fix.

Flashing Requirements
- PC & OS: Windows PC (Windows 7 or newer) with admin rights for Qualcomm drivers and tools.
- Flashing Tool: QGDP Tool or QPST (QFIL) configured for the Mobiistar CQ CPB package.
- Drivers: Qualcomm HS‑USB QDLoader 9008 drivers to detect EDL mode.
- Bootloader & Modes: Stock bootloader; enter EDL (Emergency Download) mode via volume keys or test points.
- Data & Wipe Behavior: CPB flashes typically wipe data and NV items; back up personal files and NV/IMEI if possible before proceeding.
- Device Verification: Confirm Mobiistar CQ model (check labels/About Phone) and ensure no hardware mismatches.
- Battery & Cable: 50%+ charge and high‑quality USB cable/port for stable connection during large CPB flashes.
How to Flash the Firmware
- Download the desired build: Choose either Mobiistar_CQ_V1.12_180514.1_7.0_CPB.zip or V1.14_180620_7.0_CPB.zip for the Mobiistar CQ and extract if needed for the tool.
- Install drivers and tool: Install Qualcomm QDLoader drivers, open QGDP Tool or QPST QFIL, and load the CPB file or associated XML/programmer images.
- Enter EDL mode: Power off the phone, hold volume up/down (or use test points), and connect via USB so the tool detects port 9008.
- Start flashing: Select the CPB package in QGDP/QFIL, ensure partitions are loaded, and click Download/Flash to begin writing to the Mobiistar CQ.
- First boot: After tool success, disconnect and power on; initial Android 7.0 boot may take several minutes for modem calibration and cache rebuild.

Frequently Asked Questions (FAQs)
Which V1.12 or V1.14 CPB build to use for Mobiistar CQ?
V1.14 (2018‑06‑20) is newer than V1.12 (2018‑05‑14); start with V1.14 unless matching a specific prior software state.
Is QGDP or QPST required for these CPB files?
Yes, these are CPB format ROMs for Mobiistar CQ, flashed via QGDP Tool or QPST QFIL in EDL mode.
Can these ROMs fix a CQ stuck in bootloop or logo?
Yes, CPB flashing restores modem/NV and system partitions, effective for bootloops from updates or root failures.
Why Google Drive mirrors instead of official Mobiistar?
Manufacturer servers discontinued; these are preserved stock CPB packages for legacy CQ support.
Is bootloader unlock needed for CPB flashing?
No, QGDP/QPST use EDL mode on Mobiistar CQ, bypassing the bootloader for deep recovery.
Can data be preserved with these CPB ROMs?
Typically not; full CPB flashes wipe data/NV for clean recovery, so backups are mandatory.
