I read that i can do this with a memory card. i dont have a memory card. Is there a way to downgrade the drive without a memory card ?? Please let me know,

The question is: Why do you want to downgrade? Maybe we can help you with "the problem" that you have with your actual firmware (I guess you have maybe FW4.7SP10, don't you?)

It can be that he have not the 4.7 SP10 SSP installed and can not select the version 4.7 SP10 in the HW Catalog. The SSP for V4.7 SP10 for starter can be downloaded here: https://support.industry.siemens.com/cs/ww/en/view/109757079 Regards Christoph

Thanks again,

The FW update V4.7 HF 11 have a amount of 111 MB , so you need no 3GB Card to perform the change. you say you have upgrade the drives by mistake, for this you must have use a memory card or? Then why not use this card for the downgrade? Regards Christoph

Also i thought the drive will not support SD cards bigger than 2GB. Attachment Upgrade_1.PNG (98 Downloads)
