Welcome to EpoS Wizard!
I m new to this form, please pardon me for any mistake
I just bought a used Sam4s sps2000 register. After trying few times it got hanged and I rebooted it.
After that it stuck at sam4s and rest of the screen was black. I tried couple reboots but same thing.
After that I found the way to go to boot loader screen and cleared the memory but again same issue. Not knowing much I pressed some buttons in boot loader now when I reboot it’s only blank screen and if I try clear memory again, it shows only black screen
Please help me
Found online somebody mentioned can be corrupted rom.
If this is correct can somebody please provide me

bootrom, ramdisk, app, xlib, zimage and etc
Thanks
