Flashing Requirements
- Windows PC or laptop with the latest Xiaomi / Mi Flash Tool installed to handle kunzite Fastboot TGZ packages reliably.
- Original or high‑quality USB‑C cable to keep a stable Fastboot connection throughout the flashing process.
- Unlocked bootloader on the Redmi Note 15 5G, as Xiaomi Fastboot ROMs will not install on locked devices.
- Battery charged to at least 60% so the phone does not power off mid‑flash and corrupt system partitions.
- Complete backup of apps, media and internal storage because a clean Fastboot flash normally wipes all user data.
How to Flash the Firmware
- Download the kunzite OS2.0.206.0.VPQCNXM Fastboot ROM above and extract the TGZ file on your PC until you see the images and script files.
- Install Mi Flash Tool and Xiaomi USB drivers, then power off the phone and enter Fastboot mode using the hardware key combination.
- Connect the Redmi Note 15 5G to your PC, open Mi Flash Tool, select the extracted kunzite firmware folder and confirm that the device is detected.
- Choose the preferred mode (clean all is recommended to solve bugs) and press Flash, avoiding any movement of the cable until Mi Flash shows success.
- Reboot the phone from Mi Flash or manually; the first HyperOS 2.0.206.0 boot can take several minutes while the system optimizes apps and applies stability fixes.
For step‑by‑step visuals with screenshots and videos, follow the dedicated Xiaomi Mi Flash Tool guide, and if you prefer using the included Fastboot scripts such as flash_all.bat, also review the Fastboot script flashing tutorial while working with this kunzite ROM.
Frequently Asked Questions (FAQs)
What issues can OS2.0.206.0.VPQCNXM help fix on Redmi Note 15 5G?
Like other recent HyperOS 2 waves, this kunzite build focuses on overall stability, battery and performance tuning, and UI polish, which can reduce random lag, minor freezes and small interface bugs seen on earlier releases.
Is this firmware only for the China Redmi Note 15 5G?
Yes, OS2.0.206.0.VPQCNXM is a China‑region ROM for Redmi Note 15 5G, and flashing it on non‑China or cross‑region devices risks modem, language, Google services and OTA compatibility problems.
Does the kunzite China ROM include Google Play Store?
No, the China firmware ships without Google Play Store or GMS, so you must use Chinese app stores or attempt manual GMS installation if local regulations and bootloader status allow.
Will flashing this Fastboot ROM erase my personal data?
Using Mi Flash in clean‑all mode will fully wipe apps, settings and internal storage, so backing up your data before installing the kunzite Fastboot ROM is strongly recommended.
Can this update completely remove HyperOS 2 bugs?
No update can guarantee a totally bug‑free system, but Xiaomi’s HyperOS 2 bug‑fix bulletins show ongoing improvements to lag, battery behavior, UI inconsistencies and stability, so OS2.0.206.0 should deliver a noticeably more refined experience than first‑wave builds.
Will I still get OTA updates after flashing this ROM?
If your phone is an original China Redmi Note 15 5G on the correct kunzite China ROM, OTA updates should normally continue, though factors like an unlocked bootloader or heavy modifications can influence Xiaomi’s update policy.
