- Common Fault Symptoms & Motherboard Diagnostics:

* No Service / Emergency Calls Only:

- SIM card is detected, operator name displays or SIM prompt appears, but signal indicator displays an empty circle (⊘) or stays permanently on "Emergency Calls Only".

* Manual Network Search Failure:

- Running a manual operator scan in Settings results in an immediate "Error while searching for networks" prompt, indicating MT6177MV failed to sweep the frequency bands.

* Radio Power Off (*#*#4636#*#* Menu):

- In Android Testing Menu, "Mobile Radio Power" appears toggled OFF and automatically flips back to OFF when turned ON.

* Unknown Baseband Version:

- In "About Phone", the Baseband version is reported as "Unknown", caused by MT6177MV failing its startup handshake or shorted VDD_RF supply rails.

* 2G Works but 4G LTE Fails:

- Phone registers and completes phone calls on 2G mode, but switching preferred network type to 4G LTE causes total signal loss due to defective LTE receiver mixer blocks inside MT6177MV.

* RF Section Heating & Battery Drain:

- The metal shielding can covering MT6177MV gets excessively hot during phone calls or when mobile data is turned on, accompanied by rapid battery drain.
