The Xiaomi Redmi 7 and Redmi Y3 (codename onc), both launched in 2019, were part of Xiaomi’s successful strategy to bring advanced features to the budget segment. Sharing the same core hardware platform, both devices boasted a modern aesthetic with a large 6.26-inch “Dot Drop” display and a stylish “Aura Smoke” gradient design. They were powered by the capable Qualcomm Snapdragon 632 chipset, offering a major performance leap for their class, and included a massive 4000 mAh battery for excellent endurance. The primary distinction was the Redmi Y3’s focus on selfies, featuring a high-resolution 32MP front camera specifically marketed in India. For owners of either of these popular devices, this page provides the official India (IN) Fastboot ROM, essential for unbricking a phone, performing a clean factory restore, or resolving software issues.
Important: You must verify that your device codename is onc. This firmware is not compatible with the smaller Redmi 7A (onclite) or the more powerful Redmi Note 7 (lavender). Flashing the incorrect ROM will hard brick your device.

FAQs
Q1. What is the difference between the Redmi 7 and Redmi Y3?
Both phones share the same onc codename and core specifications (Snapdragon 632, 6.26″ display, 4000mAh battery). The main difference is that the Redmi Y3 was exclusively released in India and featured a 32MP front-facing camera for enhanced selfies, while the standard Redmi 7 had an 8MP front camera.
Q2. Can I flash a Redmi 7A (onclite) ROM on my Redmi 7 / Y3?
No, absolutely not. The Redmi 7A (onclite) is a different model with a smaller screen and a different chipset (Snapdragon 439). Flashing its ROM on an onc device will hard brick it.
Q3. What was the final official update for the Redmi 7 / Y3?
Both the Redmi 7 and Redmi Y3 launched with Android 9 Pie and received MIUI updates up to MIUI 11. They did not receive an official major Android OS upgrade to Android 10. The firmware provided here is a late-stage MIUI 11 build based on Android 9.
Q4. Is this an official and safe ROM to flash?
Yes. The link provided is a direct download from Xiaomi’s official servers (bigota.d.miui.com). It is an untouched, official fastboot ROM for the Indian region (onc).
Troubleshooting
- Drivers: If your PC does not recognize the phone in fastboot mode, reinstall the Xiaomi USB drivers, run Mi Flash Tool as Administrator, or try a different USB port (USB 2.0 is often more stable).
- Fastboot errors:
- “error: not catch checkpoint” → This common error means you have selected the wrong folder. In Mi Flash Tool, be sure to select the parent folder that was created when you extracted the .tgz file, not the images folder inside it.
- “Anti rollback error” → You are attempting to flash an older firmware version than what is currently on the device. Xiaomi’s Anti-Rollback Protection (ARB) prevents this.
- EDL mode: For a hard-bricked phone that won’t enter fastboot, EDL mode is the last resort. It requires using hardware test points and is recommended for advanced users only.
