Is your Redmi Note 15 5G (codenamed kunzite) stuck in a bootloop, showing the new HyperOS bugs, or refusing to take official OTA updates? Reliable device restoration starts with downloading official Xiaomi/Redmi Fastboot firmware—especially when system errors, heavy bricking, or severe software conflicts prevent normal operation.
This page delivers the original Fastboot firmware (OS2.0.206.0.VPQCNXM, October 2025) for the Redmi Note 15 5G China model. This ROM is perfect for:
- Resolving deep bootloops, black screen, and heavy system crashes
- Recovering from failed HyperOS or root/custom mod attempts
- Upgrading cleanly to Android 15 / HyperOS 2.0
- Going back to 100% official Xiaomi/Redmi system software
If you’ve encountered Google Play Service errors, sudden 5G drops, or touchscreen freezes after recent OS updates, this ROM can help restore your phone’s stability.
Do NOT attempt to flash this file on global, India, or other non-China devices; this can PERMANENTLY brick your phone.
Always verify your device’s region and codename before flashing.
Flashing this firmware wipes ALL data including internal storage. BACKUP everything!

Frequently Asked Questions (FAQs)
- Is it possible to flash this firmware on Global or India units?
No. This ROM is specific to the China-only “kunzite” variant. Flashing on Global/India EEA models will brick your phone. - What should I do if the phone won’t boot after flashing?
Double check that you used the correct firmware and flashing tool. If stuck in bootloop, try a factory reset from Recovery, then reflash. If persistent, hardware test or service center may be needed. - Does this firmware support Google Play?
As a China MIUI/HyperOS build, it lacks Google services by default, but Google apps can be installed manually after first boot for most China Xiaomi phones. - Bootloader lock status after flash?
The device remains unlocked after flashing Fastboot firmware. Re-lock only via official methods, and never on a modified system.
