Q1: Will flashing remove the network lock (SIM lock)?
No. Flashing removes only the user security code. To remove a SIM lock, you need a separate NCK unlock code.
Q2: My Nokia C1-01 shows "Contact Retailer" after flashing. What do I do?
This means you flashed the wrong firmware variant. Re-flash with the correct product code firmware.
Q3: Can I use a USB to TTL (serial) cable instead of CA-101?
Yes, but it is more complex. You would need to interface with the phone’s RX/TX pins. Not recommended for beginners. Firmware details:
Q4: After flashing, the IMEI is lost. How to restore?
This is rare. You would need to use a tool like "Infinity Box" or write back the original IMEI using a certificate backup. Always back up your PMM sector before flashing.
Q5: Is there a free tool other than Phoenix?
Yes, "JAF" (Just Another Flash) can flash Nokia BB5 phones like the C1-01, but Phoenix is more user-friendly.
