Ariva 103 RS232 Firmware Update Issue: Wrong Version Loaded, All-On Display, EromUpgrade Steps

The problem arose as a result of loading the wrong firmware version from USB (for model 203).
All On on the display of the device.
I made an attempt to upload the software to Ariva 103 via RS232 using the information on the electrode and satkurier.
1. EromUpgrade and firmware downloaded from the manufacturer's website.
2. Connecting the notebook with the decoder via USB port> USB / RS232 converter> null modem cable.
3. I run the LZMA program twice.

EromUpgrade is as follows:
Check serial port status.... Done

Start downloading is 100%
Click "Next" to start burning. Old data will be lost. And the process CAN NOT interrupted. Click "Back" to re-download.
I click Next
Star burning. DO NOT power off!
comes to 100%
Program upgrade finished successfully
Click "Next" to upgrade other data.
Click "Finished" to exit.
I click finished
The program closes, but it stays on the decoder all the time and nothing happens. Switching the device off and on again does nothing.

You have to keep trying until you succeed. See programs from other models - Amiko, Openbox, Cryptobox.

I have already tried 10 times, I wonder if I am missing an activity.

What, what, how? What about what I gave other decoders?
The upload procedure is known and you cannot skip anything.

What, what, how? - I use EromUpgrade software and firmware downloaded from the manufacturer's website for the update
What about what I gave other decoders? - ???
The upload procedure is known and you cannot skip anything. - In the first post I described the course of my update. If the procedure is known, where is it described? On the manufacturer's website I did not find anything about it, the update was made based on information from the satkurier and electrode for other Ariva decoders.

You can see with programs from other decoders what the ALi 3511-Cryptobox, Amiko, Openbox processor have. Here you have to download. After unpacking, click 2x the LZMA file. We load Allcode + bootloader. RS232 null interlaced modem cable.
The uploaded file should be without a folder. A computer that has an RS232 port is best suited, because with adapters it is different. Windows 98 or XP is best suited.
