This is my guide on how to change the lockscreen wallpaper for 7.4.1!
MAKE A BACKUP!(TWRP)
What i used..
1.7zip - 7-Zip
2.Windows 7
3.ES File Explorer from amazon market place
lets get right into it..
1.You will need good resolution pictures
recommended size: portrait: 600x1024 and landscape: 1024x600
1.5.Open ES File Explorer
2.navigate to system/framework/
3.Make a copy of your framework-res.apk and put it on your SD card in a safe folder.
4.you can take another copy or the copy that you put on the SD card and put it on your desktop.
5.open the apk with 7zip and navigate to framework-res.apk\res\raw-hdpi\
(this is where your portrait & landscape pictures go)
6.now rename your own pictures accordingly to each picture in res\raw-hdpi\ and when done drag all of your images ontop of those in that folder and replace the originals.
7.once done exit and save.
8.now place the framework-res.apk back into your kindles SD
9.copy from SD and paste in /system
10.now hold the apk and bring up the menu and go down to properties then change permissions to rw - r - r
11.now copy again and paste in framework/ and copy over the original apk.
12.it will probably be laggy and reboot. which is fine,
if not hold power button to manually reboot.
13.you should now have your custom lockscreen pictures.
