Alright I know I have seen the things that my device might get bricked and I took the risks. So I had 220.127.116.11 Amazon OS and I got safestap and I got a ROM I didnt make a backup though :/ And today I wanted to update my kindle by uninstalling recovery for safe stap on stock os. BUT stock os wouldnt load it keeps staying at the logo. So I tried to reset the kindle by pressing volume button and power button. And now my stock rom still doesnt work but I still have safestrap. (3.70) and my rom slot 1 is gone :/ anyone can help?
