Possible Issues and Specific Reasons
| Possible No Modem Firmware Issues | Specific Reason |
| iPhone stuck on “No Service” despite inserting SIM | This usually points to a faulty or desoldered baseband IC. Common triggers include prior board-level damage, flex from drops, or thermal shock. A baseband reballing or IC replacement is often required to restore the signal. |
| IMEI shows “Unknown” or disappears entirely | A corrupted baseband EEPROM or NVRAM can cause the IMEI to vanish from system diagnostics. Restoration typically involves low-level EEPROM repair or baseband circuit reprogramming using advanced tools. |
| Cellular data grayed out in settings | A broken communication path between the modem firmware and iOS kernel can disable mobile data access. This may require a DFU restore, baseband flash rewrite, or micro jumpers if board-level damage is confirmed. |
| Unable to activate iPhone or fails SIM detection | Modem firmware absence or mismatch during iOS updates can break SIM card recognition. Deep firmware flashing using IPSW or reconfiguring the baseband logic manually often brings devices back online. |
| Calls dropping immediately after dialing | A degraded RF amplifier or unstable modem handshake can cause repeated call failures. Testing signal integrity and reflowing key radio components can stabilize baseband connectivity. |
| Modem firmware missing after battery drain or reset | An interrupted update or voltage fluctuation during factory reset can lead to missing modem partitions. Full board diagnostics, followed by modem patching through DFU mode is often needed to revive connectivity. |

FAQs
Why is my iPhone 16 Plus stuck on “Searching” even with a valid SIM?
If your iPhone constantly searches for a signal without locking onto any network, it’s likely the modem firmware has failed or gone missing. This can stem from baseband corruption, update glitches, or a hardware fault inside the RF chain.
Can overheating damage the modem firmware on my iPhone 16 Plus?
Yes, prolonged heat exposure during gaming or charging can weaken solder joints around the baseband IC. Over time, this leads to communication failure between the modem and logic board, which wipes out your signal and data functions.
Why does my iPhone reboot during activation or carrier setup?
Sudden reboots during carrier activation often point to a faulty or incomplete modem handshake. This may be due to missing firmware partitions or deep-level baseband corruption, which needs expert reprogramming or hardware-level intervention.
Can a modem firmware issue affect FaceTime or iMessage activation?
Absolutely. Both FaceTime and iMessage rely on SIM-based network authentication. When the modem firmware on an iPhone goes out of order it won’t be able to detect any network and result in failing to activate the services.
Is it possible to recover modem firmware without replacing the board?
In many instances, yes. Our certified technicians first attempt a low-level DFU flash or modem patch. If the firmware loss isn’t tied to physical baseband damage, your original board can often be revived without needing a full replacement.
