Realme C60 - C61 - C63 - Note 60 (RMX3933) — Downgrade & Baseband Fix [Tested File]

🔧 Realme C60 / C61 / C63 / Note 60 (RMX3933) — Downgrade & Baseband Fix [Tested File]

If your Realme C60, C61, C63, or Realme Note 60 (RMX3933) is showing problems like no network, unknown baseband, or missing IMEI, you're not the only one. Many users are getting stuck after flashing or updating their phone.

But don’t worry — I faced the same issue with a customer's Realme Note 60, and I found a working downgrade + baseband fix that solved it in 10 minutes. No box, no complicated tools — just the right file.

🧑‍🔧 My Repair Shop Story

A few days ago, someone brought a Realme Note 60 (RMX3933) to my shop. The phone turned on, but it had:

• No SIM signal
• “Baseband: Unknown” in settings
• Both IMEI numbers were missing
• Couldn’t make calls or use mobile data

The problem started after they flashed the wrong region firmware (they used an Indian build on a global device). This caused the baseband/modem file to break.

I tried everything: re-flashing the official OFP, factory reset, SP Flash Tool — nothing worked… until I found this special downgrade + baseband fix.

I flashed it, and boom — network came back, IMEI restored, and no errors. Happy customer ✅
