Flashing Requirements
Before flashing any Comio X1 firmware, prepare the following to reduce errors and avoid damage.
- Windows PC or laptop with stable power, plus a good quality micro‑USB cable.
- Installed MediaTek USB VCOM / CDC / preloader drivers so the X1 is detected in BROM/Download mode.
- Latest compatible SP Flash Tool and the extracted firmware package (ZIP/RAR fully uncompressed on your PC).
- Comio X1 phone with at least 60–70% battery charge and original or reliable replacement battery.
- Complete backup of personal data where possible, and if you are a technician, a backup of NVRAM/IMEI and important partitions before any “Format” operation.
How to Flash the Firmware
Both Comio_X1_MT6737T_24072018.zip and Comio_X1_V127_user_07062018_1532.rar are flashed with SP Flash Tool using a similar MediaTek procedure.
Quick steps – SP Flash Tool (for both ROMs)
- Install MTK USB drivers on your PC, then extract the chosen Comio X1 firmware package and SP Flash Tool to separate folders.
- Open SP Flash Tool, load the scatter file from the firmware folder, and choose the desired mode: “Download Only”/“Firmware Upgrade” for safer repair, or “Format + Download” only if partitions are badly corrupted.
- Power off the Comio X1, disconnect and reconnect it to the PC via USB (often with Volume Up or Volume Down held) so the tool detects the device in preloader/BROM mode.
- Click the Download button in SP Flash Tool and wait while the ROM is written; do not touch the cable or the phone until a green success tick appears.
- Disconnect the phone, then long‑press the Power key to boot; the first startup after a full flash can take several minutes while Android optimizes apps.

Frequently Asked Questions (FAQs)
What problems does this Comio X1 firmware fix?
The official ROMs typically resolve bootloops, stuck logo, constant app crashes, malware‑infected systems, failed OTA update issues, and instability caused by custom ROMs or root modifications. In many cases, they also restore missing system apps, improve network performance, and fix random freezes that appear as the device ages or storage becomes fragmented.
Which file should I use: MT6737T_24072018 or V127_user?
Use Comio_X1_MT6737T_24072018.zip first for normal software repair, bootloop fixes, or to refresh the OS with minimal risk of altering modem/NVRAM content. Choose Comio_X1_V127_user_07062018_1532.rar when the device is hard‑bricked, does not boot at all, or partitions are badly damaged and require a more complete service‑level firmware package.
Is this firmware compatible with all Comio X1 variants?
These packages are intended for the standard Comio X1 with MT6739/MT6737T platform, 2 GB RAM and 16 GB storage sold mainly in India. They must not be used on Comio X1 Note or any other Comio model, as cross‑flashing can permanently brick the device.
What should I do if SP Flash Tool shows errors?
Common MTK errors are often solved by reinstalling drivers, trying a different USB port or cable, using another SP Flash Tool version, or re‑extracting the firmware to ensure no file is corrupted. If errors persist, search for the exact SP Flash Tool error code together with “Comio X1” and your firmware name, or ask for assistance in the comments with screenshots and details.
