Download the image
The full image, to install on the receiver from a USB stick. New versions then come as updates over the internet, from the receiver's menu.
HD Satelit 0.7.4 beta for Vu+ Ultimo4K, with no warranty (GPLv2). A tester has tried it on a Vu+ Ultimo4K and it works. It installs from a FAT32 stick, with the vuplus/ultimo4k folder. On 0.7.4 the note "Unconfirmed model" may appear at startup; it is normal and goes away in 0.7.5. Testing continues and there may be errors.
Warning: the HD Satelit image erases everything you have on the receiver now: the channel list, the settings, the plugins and programs you added, the skin and the picons. First make a copy of your settings on a USB stick: at the first start, the image brings back from it the channels, the channel lists, the antenna settings and the scheduled recordings (how they are brought back). You set up the network and Wi-Fi, the plugins, the skin and the picons again. How to make the settings copy and the image copy, step by step.

Installation steps · What each version brings
Warning: beta image
You are downloading the HD Satelit image 0.7.4 for the Vu+ Ultimo4K, at the beta stage. Before you do, read this:
- The image is at the beta stage: it runs on the receiver and testing goes on, so there may be mistakes.
- It is only for the receiver on this page. Do not install it on another model, even if it looks similar.
- The new image erases everything you have on the receiver now: the channel list, the settings, the plugins and programs you added, the skin, the picons and everything you set by hand.
- So first make a copy of your settings on a USB stick. At the first start, the HD Satelit image brings back from it the channels, the channel lists, the antenna settings and the scheduled recordings. The network and Wi-Fi, the plugins, the skin and the picons are not brought back: you set them up again.
- While the receiver is writing the image, do not unplug the power and do not remove the USB stick.
- Also make a copy of your current image: if something does not work or you want to go back, the receiver is restored from a USB stick with it; how to make both copies and how to restore the receiver is on the installation page.
- The image comes without any warranty, like any program under the GPLv2 licence: you use it at your own risk.
- You help us a lot if you tell us what does not work on the image forum or at [email protected], with the receiver model and the image version.
Installing the beta image on Vu+ Ultimo4K
HD Satelit 0.7.4 beta for Vu+ Ultimo4K, tried by a tester on their own receiver. It installs from a USB stick.
Beta: read first
HD Satelit 0.7.4 beta for Vu+ Ultimo4K, dated 13 November 2026, with no warranty (GPLv2).
A tester has tried the image on a Vu+ Ultimo4K and it works: it was written from the stick with the steps below, it recognised the model (chip 7444s, board ultimo4k) and the FBC tuner modules by itself, and the receiver ran it for several hours. There may still be problems we have not seen; tell us what you find.
This page is only for Vu+ Ultimo4K, software machine vuultimo4k. Do not put the archive on any other receiver.
On 0.7.4, the note "Unconfirmed model: software for testers" may appear at startup. That is normal: the model was confirmed after the image came out, and the note goes away in version 0.7.5.
- Writing the image replaces the installed system and its settings. Save your settings and channels first.
- Keep your current image or the official Vu+ image for Ultimo4K on your computer, so you can go back.
- You need to see the receiver display and reach the Power button on the front.
- Do not cut the power or remove the stick while the image is being written.
Step 1. Save settings and channels
- Save settings and channels with the instructions of your current image and keep a copy on your computer.
- A settings backup is not a full image. Keep the archive of the image you have now as well.
Step 2. Prepare the stick
The archive is called hdsatelit-0.7.4-vuultimo4k-20261113.zip. Inside it, the installation files are in the vuplus/ultimo4k folder.
- Use a FAT32 USB stick. Formatting deletes everything on the stick.
- Extract the archive on your computer. If the download has a checksum, compare it.
- Copy the vuplus folder to the root of the stick, so the stick has vuplus/ultimo4k/ directly. Copying the ZIP as it is does not work.
- Check on the stick that all eight files are there with unchanged names, then eject the stick safely.
vuplus/ultimo4k/imageversion vuplus/ultimo4k/initrd_auto.bin vuplus/ultimo4k/kernel_auto.bin vuplus/ultimo4k/mkpart.update vuplus/ultimo4k/reboot.update vuplus/ultimo4k/rootfs.tar.bz2 vuplus/ultimo4k/splash_auto.bin vuplus/ultimo4k/hdsatelit-model
Do not mix files from other models or other archives. ultimo4k is the folder name read by the loader; vuultimo4k is the software machine name.
Step 3. Write the image from the stick
The steps below are the manufacturer's, from the Vu+ guide and the Ultimo 4K manual. A tester wrote HD Satelit to an Ultimo4K with them. We have no measured duration.
- Switch the receiver off with the rear power switch.
- Unplug the other USB devices. Put the stick into the front USB port.
- Switch the receiver on with the rear power switch and watch the display.
- When Update! Press Power appears, press the Power touch button on the front, left of the USB port, within 5 seconds.
- Wait until writing ends. After a successful write the receiver restarts by itself.
- Remove the stick after the restart, so a new write does not start.
Step 4. First startup
At the first startup the image checks the model by itself. If it stops with the model guard message (other than the note above), photograph it, send us all the values on the screen and do not bypass the guard.
If you want to help us, read these over ssh or telnet after the first startup and send them to us:
cat /proc/stb/info/chipset /proc/stb/info/vumodel /proc/stb/info/model cat /proc/cmdline /proc/partitions cat /proc/bus/nim_sockets ls /proc/stb/lcd/ cat /sys/block/mmcblk0/size df -h /
The guard expects chip 7444s and model ultimo4k, the values also read on the tester's receiver. The other values help us complete the model's rules.
What we are still watching on the Ultimo4K (tell us what you see)
- Scanning, SD, HD and UHD channels, recording and playback, on the FBC modules and on the third slot.
- Picture and sound over HDMI, changing the resolution, the remote control and the colour front display (clock, channel, standby).
- Wired network, Wi-Fi, USB storage, CI with a module if you have one, standby and waking up.
- After a crash: the log in /home/root/logs/ or the automatic report from Support.
If writing does not start or startup stops
| Update! Press Power does not appear | Check FAT32, the vuplus/ultimo4k path, all eight files and the front port. Unplug other USB devices. Do not rename another model's folder. |
| The prompt appears but writing does not start | Check that you pressed Power within 5 seconds. Note the message before trying again. |
| Startup stops | Do not assume writing has finished just because time has passed. Note the messages on the display and the television and write to us. |
How to go back to the previous image
Put on the stick, in the same way, the vuplus/ultimo4k folder from the archive of your previous image, kept on your computer, or from the official Vu+ image for Ultimo4K. Then repeat step 3.
We have not tested going back from HD Satelit 0.7.4 on this model. It depends on the receiver loader and on reading the stick. Do not use files for another model.
Tell us what you find
Send the exact model, the tuner modules, the archive name, the steps you followed, the messages shown and what worked or did not. Every result helps us, good or bad.
The receiver does not start? Leave it on for 5 minutes with the network cable plugged in and write to us on the forum with the model. In the new versions of the image, when a start fails, the receiver sends by itself an anonymous technical report, without personal data, so we can find out why it does not start.
