Technical Specifications: Original Service Part (ORG) for Qualcomm 5G architecture.

• Model Number: PM7250B.

• Revision: 200 (or 002).

• Function: Secondary Power Management Unit. It primarily regulates voltage rails for the 5G Baseband (Modem) and RF Front-End modules.

Common Fixes:

1. Unknown Baseband: Device loses IMEI and Baseband version due to power failure in the modem circuit.

2. No Service / Signal: Inability to latch onto 4G/5G networks.

3. Boot Loop / Dead: In some architectures (like Poco F3), failure of this IC causes the system to hang or reboot (Watchdog Timeout) because the modem fails to initialize.

Compatibility: Found in devices running Snapdragon 865, 870, and 765G, such as:

• Xiaomi / Poco: Poco F3, Redmi K40, Mi 10T / 10T Pro, Mi 10.

• OnePlus: OnePlus 8 / 8 Pro / 8T.

• Oppo/Vivo: Various 5G flagship models.

Technician Note: Ensure the revision code matches “-200” (or 002). Installing a different version (like -000 or -001) is not recommended and may lead to network incompatibility.
