Error after trying to update to Operating System 7.5.4 Release (RESOLVED)

  • Hi,

    please help me resolve an error after trying to update from USB to Operating System 7.5.4 Release.

    I'm not sure if I tried to update from version older than 7.3. or not :rolleyes:.

    Anyway, I never had an error before, since I'm not experienced in troubleshooting I would appreciate some help.

    Thanks.

  • Fixed by dropping 7.3.2 OS to the root, not the OS Updates folder.

    (Hope this will help someone careless like me.:))

    Changed the title of the thread from “Error after trying to update to Operating System 7.5.4 Release” to “Error after trying to update to Operating System 7.5.4 Release (RESOLVED)”.
  • Just to be clear: This special cold start with kaos.bin in root directory of USB flash drive is only required, if the must-do interim step to upgrade via OS 7.3.2 had been forgotten. If you follow the documented steps right from the beginning from OS 7.2 to OS 7.3.2 and then further to OS 7.5.4 you can keep storing the various kaos.bin versions in the OS Update folder.


    Anyhow, this whole interim step matter only applies to classical PROFILER models. Stage users don't need to take an interim upgrade step.
