| Hardware | • Huawei J530s‑U7 (or any J‑series phone)
• USB‑A to micro‑USB cable (preferably the original)
• A Windows PC (7/8/10/11) with at least 2 GB free space | Stable connection & enough disk space for the firmware files |
| Software | • SP Flash Tool (latest stable build) – free download from the official site
• Huawei USB Drivers (install via HiSuite or the standalone driver package)
• The stock firmware for your exact model (e.g., J530sU7_4.0.0.220_20220912.bin)
• The dual‑SIM patch file (often named dual_sim_patch.bin or dual_sim_auto.zip) | SP Flash Tool writes the firmware; the drivers let Windows talk to the device; the stock firmware is the baseline; the patch is the only piece that changes the SIM flag |
| Preparation | • 100 % battery (or keep the charger plugged in)
• Full backup of personal data (photos, contacts, apps) – via HiSuite, Google backup, or a manual copy
• Enable Developer Options → USB Debugging (optional but helps detection) | Power loss or data loss mid‑flash can brick the device; backups safeguard your info |
