I published a video tutorial on my Youtube channel on how people can jailbreak their Kindles using HackerDude's WinterBreak method. Many people appreciated that video and some of them wanted to know how they can get rid of Mesquito and make Kindle Store work again.
I was not even sure how to do that. But after thinking for a while I tried this way.
I just got back to my Kindle's root directory and deleted the following three folders such as ".active_content_sandbox", "mosquito" and "apps". Then I restarted my Kindle and tried to launch the store. It took some time to load for the first time. But I managed to make the store work.
CAUTION: Before doing this you must disable OTA updates via renameOTAbin KUAL extension.
Here is the video guide to get back the Kindle Store:
Thanks a lot.
BTW this is my first post on this forum and I have created an account just today.
