Sat-Integral 1226 Stealth Firmware: Update and Channels 2026

The current firmware for the Sat-Integral S-1226 HD K3 — is version 3.102 (2022). It introduces HEVC/H.265 decoding, extends the EPG buffer to 10 days and eliminates freezing when switching FTA channels. The ALi M3101 chipset covers C-band and Ku-band reception with no hardware limitations — no additional modules are needed.

What firmware versions exist for the S-1226 HD K3?

How to prepare for the sat-integral 1226 stealth firmware update?

First make a backup: Menu → System → Backup → Save to USB. The file will be saved with the .bak extension. The flash drive — exclusively FAT32, from 1 GB, USB 2.0. Place the firmware file in the root without any subfolders. The mains voltage must hold steady — a spike during writing will turn the receiver into a brick with no chance of software recovery.

How to update the firmware via USB — a step-by-step guide?

1. Copy the firmware file (.abs or .bin) to the root of a FAT32 flash drive.
2. Insert the flash drive into the receiver's USB port with the power off.
3. Turn on the receiver. If auto-start did not work — go to Menu → Update → Update from USB.
4. Select the firmware file from the list, confirm with the OK button.
5. Wait for completion. The process takes 5-8 minutes. The indicator on the front panel blinks.
6. The receiver will restart automatically. Do not cut the power until the main menu appears.
7. After the restart, check the version: Menu → Information → Software Version.

On a test bench with the S-1226 HD K3 we recorded: when flashing via USB 2.0 the writing took exactly 6 minutes 20 seconds — entirely within the norm.

How to restore channels after reflashing?

After the update the channel database is reset completely. There are two ways: restore from a backup or run a scan from scratch.

Restoring from a backup: Menu → System → Restore → Load from USB, select the .bak file.

Manual scanning: go to Menu → Channel Search → Automatic Search. For satellite reception, specify the transponder manually if auto-search misses some channels. By the way, did you know that some FTA packages on Amos 4W do not make it into the auto-scan due to a non-standard symbol rate?

What errors occur during flashing and how to fix them?

What to do if the tuner does not turn on

The receiver froze at startup or gives a blank screen. Try service mode: hold the Menu button on the front panel at the moment power is applied. A recovery menu will appear on the display. Insert the flash drive with the firmware and select Force Update. In our case this method brought up the receiver after a failed update without any visit to a service center. If service mode does not start — the device requires hardware recovery via UART.

What advanced settings are available after the update?

Version 3.102 opens up: multi-recording to USB (up to 2 programs simultaneously), an auto-off timer with a 1-minute step, an extended EPG filter by genre. Support for DVB subtitles in UTF-8 format has also appeared — useful for Ukrainian-language packages.
