So you are saying that when going with version 0.7.9 f produced this garbage as New BCore version string....
But also when you used 0.7.9 e, it worked fine ....
Is that what you have observed ?
But again, in order this V26 version mentioned to be used, there should be there a type 02 bootcore for an R65 (such as ME75 , C72 ...).
useually this does not appear in S65...
I will recheck sources for f , to see what or if something wrong happens !...
