rt7297ah on first foto is clearly see... the pcb is simmilar to r7800 model also.
For other foto, these are switching ic also but in qfn-20 package, you may try to do few better sharp pics, respect to ic marking, before cleaning, and then also after cleaning with ipa. This may reveal one char more... but...
If all chip are on common input power rail, and share it, be sure to output of any individual chip is not shorted with its input, otherwise your router cpu is probably baked internaly.
