2. Choose “Smartphones” → “F670L”.
3. Look for “Firmware” or “Software” downloads. | File name typically: F670L_V90_XX_YY.zip (where XX = build number, YY = date). | | Carrier (e.g., AT&T, T‑Mobile, etc.) | Log into the carrier’s device support page, enter the model number F670L and select “Software Updates.” | Often carrier‑branded firmware (e.g., F670L_TMO_V90). | | Reputable Firmware Aggregators | Sites such as XDA‑Developers, Firmware.mobi, SamMobile, or AndroidFileHost host links that point back to the original ZTE files. | Verify the “Original Source” field; avoid sites that host the file themselves without attribution. | | Backup from a Working Device | If you already have a device running the desired firmware, you can extract the ROM using SP Flash Tool (see Section 4). | This is the most “authentic” copy, but be sure you’re comfortable with extracting a system image. |

Important: Never download firmware from random file‑sharing sites, torrent trackers, or forums that do not provide a verifiable source. Those files can be tampered with, contain malware, or be incomplete, which may brick the device.
