Split from HMI stuck in bootloader screen: how to fix?.

In my case the HMI was stuck in BootLoader screen, not found in TIA or ProSave. The only solution that might work, besides call Siemens Services for a replace, is do a backup pendisk. Use this tutorial:

Good Luck

Hello Murof,

Thanks for replying, I already solve my problem with firmware update by Prosave.
