Hi I was just trying to replace some icons of framework-res.apk and didn't know it should be signed. I didn't save the original framework-res.apk... I'm able to boot into TWRP with a sdcard... but I'm not sure how should I replace the file? should I login as root in twrp? how should I mount /system as RW? I have another framework-res.apk from another device but it from Nougat, this is android 9 should it work as well?
thanks for the answers.
