Flashing Requirements
- Windows PC (Windows 7/8/10/11) with administrator access.
- YGDP Tool (or compatible CPB flashing utility) that supports Comio C1 CPB files.
- Installed Comio/MediaTek USB drivers (from the firmware package or official driver pack).
- Comio_C1_171014_7.0_CPB.zip fully downloaded and extracted to a folder on the PC.
- Good quality USB data cable and a stable USB port.
- Phone battery charged to at least 50% to avoid shutdown during flashing.
- Backup of all important data where possible, since full firmware flashing can erase internal storage.
How to Flash the Firmware
- Download and extract the Comio C1 firmware package; inside you should find the CPB file, YGDP (or flashing tool), USB drivers, and a basic how‑to guide.
- Install the provided USB drivers, then launch YGDP Tool on your PC and select or configure the correct CPB firmware file for Comio C1.
- Power OFF the phone completely, click the “Start/Upgrade/Download” button in YGDP, then connect the C1 to the PC with USB (often while holding a volume key, if required by your tool setup).
- Wait for YGDP to detect the device and complete the flashing process; do not disconnect the cable until the status shows success or 100%.
- Disconnect the cable and power on the phone; the first boot after a full flash may take several minutes, so be patient.

Frequently Asked Questions (FAQs)
What issues can this Comio C1 CPB firmware fix?
It can resolve bootloops, “stuck on Comio logo” problems, repeated app crashes, and many software‑side performance issues by reinstalling the full stock Android 7.0 system and related partitions.
Will flashing this erase my apps and personal data?
Yes, a complete firmware flash typically wipes user data stored in internal memory, so contacts, apps and files may be removed; always back up anything important before you start if the phone is still accessible.
How can I be sure that my phone is the correct Comio C1 model?
Check the sticker on the box or under Settings → About phone when possible; it should clearly list “Comio C1” with 5‑inch HD display, MT6737 quad‑core CPU, 1GB RAM and 32GB internal storage.
Can I use this Comio C1 firmware on the Comio C1 Pro or other Comio models?
No, each model (C1, C1 Pro, C2, S1, P1, etc.) has its own firmware; using the wrong CPB on a different device can cause permanent brick or modem/IMEI problems and is strongly discouraged.
YGDP does not detect my Comio C1 or flashing stops with an error – what should I do?
Reinstall the USB drivers, try another cable and USB port, ensure the phone is fully powered off before connection, and verify that you loaded the Comio_C1_171014_7.0_CPB file; many detection and boot issues come from driver or connection problems.
