Oh hey guys, seems like my thread got popular after a year
Just wanted to tell you what happened, the seller replaced the unit with a different one. In my country, the forgotten stuff at an airport gets auctioned after several months. So seller bought many kindles to sell them over internet, not being aware of kindles can be blacklisted. But I couldnt be sure if the replaced kindle would be blacklisted after a while so I asked for a refund, and with some cut, I got my money back.
Then, I bought a new kindle from amazon, and I couldnt even get it because my friend was in vacation in US, and I got it mailed to his apartment, then, he got it stolen, I couldnt even open my new kindle's box
Then, finally I could get a working, not blacklisted kindle over internet from my country but I broke its screen as soon as possible, now I'm waiting for a replacement screen from china, hoping I could use my kindle happily eventually
