Hello , after alot of research online
I've managed to come up with a way to unbrick my hard bricked device Sky IM-A770K in qhsusb_dload mode with dead boot ,without having to send it to those jtag/medusa services with the help of some methods i found on some vietnames websites .

Again I do not hold responsibility for all the above steps . It worked for me maybe it'll work for you or your device could be damaged more who knows so do this on your own risk. If you chose to do this be sure to install the drivers properly. Research on how to install them if you're having trouble doing it .If this methods doesn't work for you keep researching online maybe you'll find a way.It took me a week of research before i could come up with this.
