How to Flash RedMagic 8S Pro (NX729) Stock Firmware (Fastboot / QFIL) — Fix Bootloop, Unbrick & FRP
Flashing the factory firmware is the reliable way to revive a RedMagic 8S Pro that won’t boot, unbrick it, clear an FRP lock or roll back a bad update. Here is the full procedure for the RedMagic 8S Pro. The RedMagic 8S Pro runs on the Qualcomm Snapdragon 8 Gen 2 (4 nm) chipset, so it flashes with fastboot (Android platform-tools), or QFIL for an EDL package — the Qualcomm flashing route. ROM Palace hosts 3 official stock firmware files for this model as a free, resume-supported direct download.
Before you start
- Back up anything you can — flashing erases the phone.
- Charge the battery above 50% so it cannot die mid-flash.
- Confirm your exact model code (NX729) in Settings > About phone or on the box — flashing another model’s firmware can brick the device.
- Use a Windows PC and a good-quality USB data cable (not a charge-only cable).
💡 Flashing the wrong firmware, or pulling the cable during a flash, can hard-brick the phone. Only use the firmware listed for the RedMagic 8S Pro on its ROM Palace page.
What you need
- The RedMagic 8S Pro stock firmware — download it free from the RedMagic 8S Pro firmware page on ROM Palace.
- fastboot (Android platform-tools), or QFIL for an EDL package — the Qualcomm flashing route.
- the Qualcomm USB / adb-fastboot driver installed on the PC so the tool can see the phone.
How to flash RedMagic 8S Pro stock firmware
- Install Android platform-tools (adb & fastboot) and the Qualcomm USB driver on your PC.
- If the package is a fastboot ROM, boot the phone to fastboot mode (power off, then hold Volume Down + Power) and run its flash-all script from the PC.
- If it is an EDL package, open QFIL, load the provided firehose/programmer and the rawprogram/patch files, then boot the phone into EDL (9008) mode and start.
- Keep the cable connected and the battery above 50% for the whole flash.
- Wait for the tool to report finished / all partitions written before disconnecting.
- Reboot — the first boot after a firmware flash can take a few minutes.
💡 The RedMagic 8S Pro uses a Qualcomm Snapdragon 8 Gen 2 (4 nm) SoC — Qualcomm devices often need a matching bootloader/EDL programmer — a signature or "sahara" error means the package is not for this exact model.
Common problems and fixes
- Stuck in a bootloop after an update: flash the matching stock firmware from this page to restore a clean system.
- Tool never detects the phone: reinstall the Qualcomm USB / adb-fastboot driver, try another USB 2.0 port, and connect with the phone fully off.
- FRP / Google account lock after a reset: flashing the full stock firmware clears the locked system partition.
- Battery drains fast or the phone won’t hold a charge after an update: reflash the stock firmware; if it persists, the 6000 mAh · 80W cell itself may be worn.
- Failed or interrupted OTA: a clean stock flash is the safe way back to a bootable system.
