The Xiaomi Redmi Y1 Lite (codename ugglite), also known in global markets as the Redmi Note 5A, was launched in 2017 as a highly affordable entry-level smartphone. It was designed to offer core smartphone essentials, featuring a large 5.5-inch display, the reliable Qualcomm Snapdragon 425 chipset, and a dedicated microSD card slot for expandable storage. In India, it was part of the youth-focused “Y-series.” This page provides official Global Fastboot ROMs for the device, which are crucial for users who need to unbrick a bootlooped phone, downgrade their MIUI version, or perform a clean factory restore.
Important: You must verify your device is the “Lite” or base model, with the codename ugglite. This firmware is not compatible with the higher-tier Redmi Y1 / Redmi Note 5A Prime (ugg), which has a different processor and a fingerprint scanner. Flashing the wrong ROM will brick your device.

FAQs
Q1. What is the difference between the Redmi Y1 Lite and the Redmi Note 5A?
They are the same phone with different marketing names. “Redmi Y1 Lite” was used for the Indian market, while “Redmi Note 5A” was used for the global market. Both share the ugglite codename and can use the same Global ROMs.
Q2. Can I flash this ROM on a Redmi Y1 / Redmi Note 5A Prime (ugg)?
No, this is a critical warning. The Prime model (ugg) has a different chipset (Snapdragon 435) and a fingerprint sensor. Their firmwares are not compatible. Flashing an ugglite ROM on an ugg device will cause a hard brick.
Q3. Which of the two Global ROMs should I use?
The V11.0.3.0.NDFMIXM (MIUI 11) build is the newer and final update for this device, so it is the recommended version. The V10.3.1.0.NDFMIXM (MIUI 10) build is an older version provided for users who may need to downgrade for specific reasons.
Q4. Why is the Android version still 7.1 Nougat on MIUI 11?
As an entry-level device, the Redmi Y1 Lite launched with Android 7.1 and did not receive a major Android OS version upgrade. However, Xiaomi continued to provide updates to its MIUI skin on top of the original Android base, bringing new features and a refreshed UI.
Troubleshooting
- Drivers: If your PC doesn’t recognize the phone, try reinstalling the Xiaomi USB drivers, using a different USB port (USB 2.0 is often more stable), and running Mi Flash Tool as an administrator.
- Fastboot errors:
- “error: not catch checkpoint” → This common error means you have selected the wrong folder. In Mi Flash Tool, select the main extracted folder, not the images sub-folder.
- “Anti rollback error” → You are trying to flash an older firmware version than what is currently on the device. While this device may not have strong ARB, it’s always best to flash the newest version available.
- EDL mode: For a hard-bricked phone that won’t enter fastboot, EDL mode is the last resort. It often requires test points on the motherboard and is recommended for advanced users.
