HTC flyer stuck at splash screen
I was given an HTC flyer(I think) from my brother because he said it didn't work. I'm looking to see if I can repair it. He said that he tried to update it and after the attempt, it was stuck at the splash screen. I"ve tried putting it in recovery, but after it makes an attempt, I get a red triangle with !. What are some other things I can try to restore functionality? Also, which RUU do I need to restore to factory?
the info on my bootloader screen is:
flyer pvt-ship s-off rl
