Issue
The HMIST6 does not boot, it stays on a loading screen with a blue circle.
Product Line
HMIST6 series, HMISTM6 series and HMISTO series.
Environment
HMI programmed with EcoStruxure Operator Terminal Expert 3.2 SP2 and newer.
Cause
In some cases, when a display unit failed to accept the project in a transfer operation, the HMI cannot boot and Recovery Mode must be opened.
Resolution
Here are the steps to access Recovery Mode:
1. Power off the HMI.
2. Power on the HMI.
3. While it is booting and the screen shows the green loading bar, touch and hold the bottom-left corner or bottom-right corner of the display until a dialog box asking "Do you want to enter recovery mode?" appears. It takes about 10 seconds for the dialog box to show up.
3. Click [Yes] to enter recovery mode.
4. Transfer the project, depending on your transfer method.
This recovery process was introduced on EOTE v3.2 SP2. It will not work with HMIs programmed with older versions of EcoStruxure Operator Terminal Expert. Please contact tech support if further assistance is needed.
