If your Vivo X90 PD2241BF is stuck in a bootloop, showing “No Service”, not turning on, or displaying an Invalid IMEI error, you’re in the right place. These are common issues that many users face after a failed update, rooting, or corrupted system files.
The good news? You can fix all of these problems by flashing the official firmware and repairing the IMEI number using the right tools.
This guide will show you:
The Vivo X90 is a high-end smartphone powered by the MediaTek Dimensity 9200 chipset, featuring up to 12GB RAM, AMOLED display, and OriginOS (based on Android 13/14).
All of these can usually be fixed by reinstalling the stock ROM and repairing the IMEI number if needed.
Stock Firmware (ROM) is the official operating system that comes pre-installed on your Vivo X90. It controls everything—from booting to camera, network, and apps.
When the firmware gets corrupted (e.g., due to a bad update or system crash), the device may refuse to boot or function properly.
