PS3 Different FW versions on ROS0 and ROS1 - no warning/danger?

[bob76]

Hi,

I got a CECH-2504B today and followed MrMarios guide on installing CFW. I'm hesitant in proceeding as he mentions in the video that ROS0 and ROS1 should match. In my case I get no danger or warning but when I compare the versions in the log output they appear to be different?
I updated to OFW 4.91 to try to match these two without any luck, see output below.

Would this be an issue or is it safe to proceed with installing CFW please?


******* Getting SDK versions *******
ROS0 : 491.000
ROS1 : 490.000

....

******* Checking CoreOS_region *******
009.01 ROS0 Header : OK
009.02 ROS0 Hash : OK
Size = 0x6FFFE0
MD5 = AFA10D61A1156CF56A994CA85E3B4777
Version = 4.91 CEX/SEX OFW/HFW
009.03 ROS0 unused 0xFF Filled Area : OK
009.04 ROS1 Header : OK
009.05 ROS1 Hash : OK
Size = 0x6FFFE0
MD5 = AB9C9700445CCD1AB9215AF8C28EE0F9
Version = 4.90 CEX/SEX OFW/HFW
009.06 ROS1 unused 0xFF Filled Area : OK

Found the solution: After flashing the official firmware file once again (two times in a row) it now states the identical versions and MD5 hashes for ROS0 and ROS1.

As you indicated, as there were no warnings you were fine to proceed. The ROS0 and ROS1 banks alternate; so for example if ROS0 had 4.90 on it, and you installed 4.91 then ROS1 would have that on it. If you then reinstalled that same firmware a second time, ROS0 would then be the same as ROS1 as is the case with your console now. Anyway, no worries whatsoever.
