What can be the suitable patch update (NOT UPGRADE) for X460-48 t having image 22.214.171.124 ?
The latest patch is always recommended of any version of code (For 126.96.36.199 it is 1-14). When you "update" the patch it is like performing a upgrade and will be placed on the opposite partition. I would not recommend sticking on the 15.3 code considering it is out of support. The current recommended code for the x460 is 188.8.131.52.
