The Mobicel R9 Plus is a mid-range Android smartphone built on the Qualcomm MSM8937 Snapdragon 430 platform. With 2GB RAM and 16GB storage running Android 7.1.2 Nougat, it was a fair performer on release—but as common with all Snapdragon-based Mobicel phones, performance can deteriorate over time. Users report issues like persistent freezing, random reboots, app crashes, system lag, and the device failing to progress beyond the Mobicel logo (bootloop). Software partitions can become corrupt due to failed system updates, malware, or even hardware wear, and the only reliable fix is a full, clean reflash using QFIL/QPST and the official stock ROM.
This pack contains the tested, officially compatible QFIL (firehose, rawprogram) firmware for the Mobicel R9 Plus. You must use QFIL or QPST—not SP Flash Tool or SPD tools—for all Qualcomm chips.

Why Flash This Specific Firmware?
- Fix Bootloop and Logo-Stuck: If the phone cannot boot past the Mobicel or Android logo, QFIL/QPST reflash replaces all partitions with clean, official images.
- Repair Persistent Freezing or Random Reboots: Software-level flash can resolve boot cycles or unexpected shutdowns not caused by hardware failure.
- Restore Function After Failed Modding or OTA Updates: If a bad root, custom ROM, or buggy OTA left the phone bricked, QFIL full firmware will return it to original factory state.
- Unbrick Qualcomm EDL/9008 Devices: If the phone enters Emergency Download (EDL/9008) mode, QPST/QFIL is the only method to recover.
Crucial Prerequisites Before Flashing
Backup all important files. QFIL or QPST erases everything (apps, user data, settings, accounts, etc).
- Official QPST suite (includes QFIL) or standalone QFIL tool.
- Qualcomm USB drivers installed on your Windows PC.
- Charge to at least 50% before proceeding. Do NOT interrupt flashing!
How to Flash the Firmware
- Download and extract
Mobicel_R9_Plus_MSM8937_V21_270917_QPST.zip - Install Qualcomm USB drivers if not already done.
- Open QFIL.exe from the QPST/QFIL suite.
- From the tool, select “Flat Build” and choose the
prog_emmc_firehose_8937.mbnfile from the firmware folder. - Load the
rawprogram.xmlandpatch.xmlfiles as instructed in tool panels. - Power off the phone and boot into EDL/9008 mode (usually by holding Volume Up + Volume Down while connecting to PC via USB).
- Let Windows detect the Qualcomm HS-USB QDLoader 9008 port.
- Click “Download” in QFIL/QPST and wait until the process completes successfully.

Disclaimer: Flashing with QFIL/QPST is advanced and risky. Proceed only if fully familiar; the process cannot be undone and may permanently brick the phone if interrupted or done incorrectly.
