A very irritating thing in the kindle touch, especially for those who don't use the kindle store, is the store button on the search bar. We could remove this in < 5.1.0 but now that doesn't work. Here's how you turn that button into a browser button (detailed enough for a noob to follow):
First download the attachment, extract it and save "store.png" in /mnt/us i.e the usb drive.
Then ssh into the kindle and enter in:
mv store.png store.bak
mv store_active.png store_active.bak
cp /mnt/us/store.png .
cp /mnt/us/store.png ./store_active.png
cp search_bar.js /mnt/us
Connect up the USB drive and open up search_bar.js with A PROGRAMMER'S EDITOR, OR ELSE YOU WONT HAVE UNIX LINE BREAKS!!!
After the comments you will find a line (somewhere between line 20-30):
const STORE_ID = 'app://com.lab126.store';
Replace this with:
const STORE_ID = 'app://com.lab126.browser';
Now save this and ssh back into the kindle and enter:
mv search_bar.js search_bar.bak
cp /mnt/us/search_bar.js .
And voila! You have a browser button on the search bar.
