Locating the class by strings isn't very hard. But decompiling and regenerating the jar file probably needs a lot more work. (I thought they had framework jars codesigned?)

Since you mentioned kaf.jar, maybe people will find "shop kindle store" menu needs a bit more love as well

I'm not trying to do that, I can just change the strings. I'm just afraid that on one of the many firmware/device variations, one .class file gets corrupted and it makes the entire kaf.jar unable to run, essentially bricking the device.

Maybe I could release a script that injects copies of the .class files with the strings, then asks the user to verify them manually before updating kaf.jar.

It's easy to verify a .class file by by simply decompiling it online on a site like this for example. If it's corrupted then the decompiler will throw an error.

You mean the one in the top right menu?

Amazon has their weird logic controlling what icons are shown. (You might see less/different depending on registration/market/kids mode)
Those jar files changes with each firmware so I'd say a short writeup would be much more practical than scripts.

Yeah, I was under the wrong impression that amazon injected that menu systemwide few years ago. Turns out it's been there since the original kindle. sigh
