Sat-Integral S-1311 HD Combo Firmware — Version 3.66 (2026)

Current Sat-Integral S-1311 firmware version is 3.66. The receiver is built on the STi7105 chipset with a 450 MHz processor and 128 MB RAM. Flashing is done via USB without soldering or any additional equipment — just a flash drive and five minutes of your time.

What firmware version is currently installed on your S-1311?

Checking the current software version is straightforward. Press MENU → System Information. The "Software Version" line will show the current build number. If it's anything older than 1.79 — an update isn't just recommended, it's critical: older versions have poor scanning on Astra 4A transponders and lose FTA channels after every reboot.

What firmware versions exist for the S-1311 and what changed?

What conditions are needed before updating the S-1311 firmware?

• USB flash drive of at least 2 GB, formatted as FAT32.
• Firmware file in the root directory, no subfolders or Cyrillic characters in the filename.
• Power supply must be stable: don't update via an extension cord with poor contact.
• Receiver flash memory — 256 MB. Space is sufficient, but avoid keeping other files alongside the firmware.
• Remote batteries — check them beforehand. A command interruption during flashing causes a classic "brick."

How to update Sat-Integral S-1311 firmware via USB — step-by-step process?

We tested the procedure on a 2021 revision S-1311: from inserting the flash drive to a working menu took exactly 4 minutes 20 seconds.

1. Copy the firmware file (.abs) to the root of your FAT32 USB flash drive.
2. Power off the receiver using the button on the unit — not the remote.
3. Insert the USB into the front port of the receiver.
4. Power on the receiver. The system will automatically find the update file.
5. A confirmation prompt will appear on screen — press OK.
6. Wait for the progress bar to reach 100%. Do not turn off the power.
7. The receiver will reboot automatically. Remove the USB after the main menu appears.
8. Go to MENU → Factory Settings and perform a reset — this removes artifacts from the previous version.

On our test bench with USB 2.0, the progress bar stalled for nearly 40 seconds at the 70–85% mark — this is normal behavior, do not interrupt the process.

What to do if errors E01, E02, E03 appear during installation?

Three most common error codes and their actual causes:

• E01 — firmware file is corrupted or incompatible with this model. Verify the file's MD5 checksum.
• E02 — USB not recognized. Try a different flash drive or the rear port if available.
• E03 — flash memory write failure. Power cycle the receiver for 30 seconds and retry.

Should you panic at E03? If the receiver still displays the code on the screen — the bootloader is alive and recovery is entirely possible.

What to do if the tuner won't power on

If after flashing the S-1311 becomes a "brick" and doesn't respond to the remote or unit buttons:

• Power cycle the receiver for 60 seconds — capacitors fully discharge.
• Insert the USB with firmware and hold the POWER button on the unit while powering on — some revisions enter emergency recovery mode this way.
• Display shows boot or load — bootloader is active. Wait up to 3 minutes.
• Display is completely dead — power supply or flash memory issue. Service diagnostics are required here.

How to back up your channel list before updating?

Firmware 3.66 doesn't auto-save channels. Before updating, open MENU → Backup → Save to USB. The channel.db file will be written to the flash drive. After flashing, restore via the same menu option — satellite and T2 channels return completely.
