It all started when I tried to delete an archived variable of large size. It was probably a system file. The calculator froze and displayed random ASCII characters on screen. Same characters popped up, even when turned off and turned back on.
When I put batteries in and press ON, static on screen. The same exact pattern of static appears when the calculator is turned off and on. None of the buttons work. The only way to turn it off is to take batteries out. I initially thought it was the batteries, but when I put brand new batteries in, it still happens. I tried to connect it to computer via USB Direct Cable, but the USB port does not recognize anything. I cannot go into the settings to reset it since the calculator is essentially bricked. I am not sure if I accidentally corrupted the calculator or not. I need your help, please.
