[Q] Caterpillar cat b15 translating system.
A week ago my dad bought cat b15 dual sim phone. Everything is ok except the menus. Of course i can change language settings to polish but it doesnt solve the problem-some options are still in english which makes my dad angry becouse he doesnt understand what should he click. So heres my question: How to translate the things which are still in english? I have already searched a bit and i think best would be pulling apk files with adb decompiling them then editing english leftovers in xml files and recompiling then pushing back to the device. Am i right? Maybe some of you could help? (only technical stuff ill do the translating job myself) I'll be really greatfull.
