Flashing Requirements
- Confirm codename blue by booting to fastboot and running fastboot getvar product on a PC; flash only if it returns “blue”.
- Unlock the bootloader; Xiaomi fastboot ROMs cannot be installed on a locked Redmi A3 / POCO C61.
- Have a Windows PC, Xiaomi USB drivers, Xiaomi Mi Flash Tool (or a compatible fastboot flasher), a reliable USB‑C cable and at least 10 GB free space.
- Charge the phone to at least 60 % to reduce the risk of shutdown and extra heat during the flash.
- Back up all important data, as “clean all” fastboot flashes will erase apps, settings and internal storage.
How to Flash the Firmware
Fastboot ROMs (.tgz) via Xiaomi Mi Flash Tool
- Download the correct blue_…_images_V816… file for your region and extract it until the images folder and flash_all*.bat scripts appear.
- Install Xiaomi USB drivers and Xiaomi Mi Flash Tool on your PC, then open Mi Flash and select the extracted firmware folder.
- Boot Redmi A3 / POCO C61 into fastboot mode, connect it via USB and click “Refresh” in Mi Flash to ensure the device is detected.
- Select the clean all option for a fresh install, click “Flash” and wait until Mi Flash reports success without disconnecting the cable.
- Reboot; the first Android 14 start may take several minutes while the system optimizes apps, after which performance should be more consistent if the old install was badly corrupted.
For detailed, illustrated tutorials, follow these guides: how to flash with Xiaomi Mi Flash Tool, how to use a flash_all.bat fastboot script and how to manually install official OTA updates via recovery/ADB sideload.
Frequently Asked Questions (FAQs)
What issues can these blue firmware files fix?
These fastboot ROMs can unbrick Redmi A3 / POCO C61 stuck on the logo, repair failed OTA updates and clear deep software errors that cause constant lag, crashes or “System UI not responding” loops.
Will V816.0.4.0/0.6.0 stop lag on my Redmi A3?
The updates bring Android 14 with a fresh system image and current security patch, which often helps if lag comes from a broken install, but entry‑level Helio G36 and limited RAM still require keeping storage clean and background apps minimal for smoothness.
Are these ROMs safe for POCO C61 as well?
Yes. POCO C61 is effectively a rebranded Redmi A3 using the same blue platform, and official trackers list V816.0.4.0.UGRMIXM as a joint Redmi A3 / POCO C61 fastboot ROM, as long as codename is confirmed as blue.
How can I confirm my phone really uses codename blue?
Enter fastboot mode, connect to a PC and run fastboot getvar product; Redmi A3 / POCO C61 units supported by these ROMs will report blue, matching Xiaomi’s firmware databases and codename lists.
