According to a post over at TX Forums
Team Xecuter has defeated the infamous corona boxes.
As promised we have defeated Corona. Full decrypted boothchain achieved and CPU key retrieved.
Xecuter does it again - 10 years and still rockin'. Greets to the haters.
More news soon - here's some screen shots of the NAND Dump - the box is still live so a few portions of info were blocked. However if you doubt this is real you should go to the back of the noob line.
