Flashing Requirements
- Windows PC or laptop with the latest Xiaomi / Mi Flash Tool installed for flashing spring Fastboot TGZ packages.
- Original or high‑quality USB‑C cable to keep a stable Fastboot connection during the flash.
- Unlocked bootloader on Redmi 15 5G / 15R 5G / POCO M7 Plus 5G, as Xiaomi Fastboot ROMs will not install on locked devices.
- Battery charged to at least 60 % to reduce the risk of shutdown and partition corruption mid‑flash.
- Full backup of apps and internal storage, because clean Fastboot flashes usually wipe user data and HyperOS settings.
How to Flash the Firmware
- Download the correct spring Fastboot ROM for your region from the table and extract the TGZ archive on your PC.
- Install Mi Flash Tool and Xiaomi USB drivers, power off the phone and boot it into Fastboot mode with the hardware key combination.
- Connect the device via USB, open Mi Flash Tool, select the extracted firmware folder and confirm that the spring device is detected.
- Select the desired mode (clean all recommended) and click Flash, keeping the cable still until Mi Flash reports success.
- Reboot the phone; the first HyperOS boot after OS2.0.204.0–206.0 may take several minutes while the system optimizes apps and data.
For a step‑by‑step tutorial with screenshots, follow the Xiaomi Mi Flash Tool guide, and if you use the included flash_all.bat script, also see the Fastboot script flashing tutorial when working with these spring ROMs.
Frequently Asked Questions (FAQs)
What issues can these spring HyperOS updates fix?
Recent HyperOS reports show Xiaomi targeting launcher lag, touch‑delay, random freezes and small UI bugs, so moving to the latest spring stable build usually improves smoothness and stability.
How do I pick the right spring ROM for my phone?
Check Settings → About phone for codename spring and region (China, Global, India or EEA), then flash only the ROM that matches your original region to keep modem bands and OTAs working properly.
Will these Fastboot ROMs erase my data?
Mi Flash clean‑all flashes erase apps, accounts and internal storage, so always back up everything important before installing any spring Fastboot ROM.
Can flashing fix HyperOS network or signal problems?
Some network issues are hardware‑related, but Xiaomi often includes modem and stability optimizations in HyperOS updates, so upgrading to the matching region’s latest spring build can help with software‑caused glitches.
Will OTA updates still work after manual flashing?
Staying on an official, region‑correct spring stable ROM usually preserves OTA support, but cross‑region flashing or extensive modifications can affect Xiaomi’s update policy.
