Extract text from Firmware update files (FOTA)
To convert FOTA Firmware updates to another format, you need Android OS or other System software.
To convert other file formats to the "Firmware Update File" file type, you need software like Android OS or a similar tool.
A .FOTA file is a Firmware Over-the-Air update package. It contains low-level system updates, operating system patches, or baseband radio firmware for mobile and IoT devices. These files are most commonly distributed by Google and hardware manufacturers to update Android smartphones over Wi-Fi or cellular networks.
The primary disadvantage of the .FOTA format is that it is highly proprietary, device-specific, and often heavily encrypted. They are practically useless on standard desktop operating systems and consume significant storage space if left undeleted. You cannot simply double-click to open them, and they require a compatible device bootloader or custom recovery environment to execute safely.
Because they contain compiled binary code and partition images rather than readable media, you cannot convert a .FOTA file to standard formats like PDF or JPG. Advanced users, however, may attempt to extract the payload into ZIP, BIN, or IMG formats to analyze the system partitions or modify the firmware.
This file format is exceptionally difficult to open or convert because it is a closed, proprietary system image. Standard online converters fail to process it because they lack the specific manufacturer decryption keys and expect standard document headers. Often, only the original device software can properly read or execute the data. If our analysis detects a supported underlying or embedded format, viewing or extraction may still be possible.
Convert.Guru analyzes your FOTA file, detects the exact format, and lets you read the text inside.
If you want to convert FOTA file to SYS, DLL, EXE, DRV, VXD, 386, COM, BAT, CMD, SCR, PIF or LNK, you can use Android OS or similar software from the "System Update Deployment" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to FOTA, try Android OS or another comparable tool in the "System Update Deployment" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our FOTA converter.
