Start with LMSA. If that fails, root and enable Diag Mode. If that fails, proceed to QCN restoration. Only as a last resort, seek hardware JTAG services.
| Error | Solution | |-------|----------| | Status: BROM ERROR: S_BROM_CMD_STARTCMD_FAIL | Reinstall VCOM drivers, disable driver signature enforcement. | | SN Write Tool: Failed to get IMEI | Phone is not in EDL mode. Try different key combo (Vol Up + Power). | | Maui META: Phone not detected | Use USB 2.0 port. Try Vol Down + Power to enter Meta Mode. |
The distinction between (restoring the original number) and changing (assigning a new number) is legally critical:
A: No. IMEI repair software writes the physical number to the chip. If the device is blacklisted by the carrier, the block is at the network level, not the phone level. Changing the IMEI to a clean number is a crime.
