• PFO (Power Amplifier and Frequency Oscillator) Issues: If you can detect networks but not your home network, the problem may lie with the PFO. To resolve a “mobile network not found” error, consider replacing or repairing the PFO.
• Network Disconnects During Calls: If your network disconnects while making calls, it could be related to the Network IC. You can try repairing or replacing the Network IC and cleaning the antenna tips and connection points on the phone.
• 26 MHz Crystal Oscillator: If you continue to receive the error message, consider heating or replacing the 26 MHz Crystal Oscillator as a potential fix.
• Jumper for Antenna Switch: If replacing the Antenna Switch is not possible, you can consider using a jumper to bypass the faulty switch if it’s accessible.
• Re-Ball or Replace ICs: For various hardware components like the PFO, Network IC, Power IC, and CPU, you can try heating, re-balling (re-soldering), or replacing these integrated circuits if necessary. These components can sometimes develop soldering or connectivity issues over time.

Please note that hardware repairs should ideally be performed by professionals or experienced technicians, especially if you are not familiar with smartphone hardware. Attempting hardware repairs without proper knowledge and tools can lead to further damage. If you’re not confident in your ability to diagnose and fix hardware issues, it’s advisable to seek help from a qualified technician or a mobile repair service.

Before proceeding with any hardware repairs, make sure to back up your data and consider the warranty status of your device, as opening the device or attempting repairs yourself may void the warranty.
