What should I do when the V-Box update firmware always failed?
1. Please download and install the V-NET Access Client version 20210617.
2. If it is V-Box E series, it maybe have prompt there are 2 version available for update, E01 and E02. Like picture below.(But if it is H series and S series, it would not have this kind of problem)
3. Close the V-NET. Go to the installation path of V-NET Access 210617. Find the following file: Up.ibl
4. Open Up.ibl as Notepad or some other similar software. Before doing this, remember to backup this Up.ibl file first.
5. Find this E2 row and comment it or directly delete it. Saved the changes.
6. Then open the V-NET again. There will be one line left after the modification. Try to update again.
7. Last use the later version to update the firmware to the date. For example version 20220628.
