The Xiaomi Redmi 7 and its selfie-focused sibling, the Redmi Y3 (codename onc), were dominant forces in the budget smartphone segment of 2019. They offered a major upgrade over predecessors with the capable Snapdragon 632 processor and a modern design. While marketed differently—with the Y3 boasting a superior front camera—both phones share the same core hardware and, critically, the same software.
However, both devices have since reached their official "End of Life" (EOL) for software support. Their final stable build was MIUI 11 based on Android 9 Pie, and they never received the much-anticipated updates to MIUI 12 or Android 10. For users still holding on to these reliable devices, having access to the official stock firmware is essential. Whether you need to unbrick your phone, fix severe performance lag, or simply restore it to a clean, stable factory state, this guide provides the official Indian firmware to get the job done.

FAQs
Q1: Are the Redmi 7 and Redmi Y3 the same phone?
They are almost identical. They share the same codename (onc), processor, and body. The only major difference is the front camera (8MP on Redmi 7, 32MP on Redmi Y3). Because of this, they use the exact same firmware.
Q2: Can I get Android 10 or MIUI 12 on the Redmi 7 / Y3?
Officially, no. Xiaomi ended support at MIUI 11 on Android 9. To get newer Android versions, you must install an unofficial custom ROM (like LineageOS or Pixel Experience) from a community like the XDA-Developers forum.
Q3: Is it safe to use a Redmi 7 / Y3 in late 2025?
For basic tasks, yes. But be aware that it has not received any security updates in several years, making it vulnerable to security threats. Using apps that handle sensitive financial or personal data is not recommended.
Q4: My screen has "ghost touch" issues. Will this fix it?
It might. If the ghost touch is caused by a software or driver calibration error, a full Fastboot flash can resolve it. However, if the problem persists after flashing, it is likely a hardware failure in the display itself.

Troubleshooting & Common Errors
- Mi Flash Tool shows a "sahara" or "xbl" error: This is a common error on older Qualcomm devices that can indicate a weak USB connection or, in rare cases, a failing eMMC (storage) chip. Try using a different USB 2.0 port and a different cable first.
- Device not detected in Fastboot mode: This is almost always a driver issue. Uninstall any old drivers and reinstall the ones linked above. Run Mi Flash Tool as an administrator.
- The phone is stuck in a bootloop after flashing: You did not select the "clean all" option. You must boot back into Fastboot mode (hold Power + Volume Down) and repeat the flashing process correctly.
- "The system has been destroyed" error appears on boot: Don't worry. This is a generic error message. Just force the phone back into Fastboot mode and flash the firmware again.
