Riverside99 Posts: 11 Rating: (0)	Hi I'm trying to downgrade the firmware in our s7-1500 6E27 516-3AN01-0AB0 from v2.6 to v1.8. So I can download a v13 program to it. We cant upgrade the program to a newer version as there are errors coming up which cant be resolved as we dont have the passwords for the know how protected blocks. So basically I need to know where can I get v1.8 firmware files for a 6E27 516-3AN01-0AB0 in order downgrade it. Hope someone can point me in the right direction. Thanks.

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
