My Sprint HTC EVO 4G asked me for update today morning.I click ok,and after update my phone just going on circles with Sprint logo.I reboot it,pull battery out,format SD card,read tons of articles about EVO recovery-nothing.It's not recognizing PC36IMG.ZIP file from fast boot,when i'm, going to recovery mode it just showing me a red triangle,and when i'm selecting "Boot from sd card How i can put my phone back to life?What is wrong with this stupid update???I need my phone back ASAP.It's a stock Sprint phone,never did any software changes,rooting or anything else,just phone\mail\soft from Android Market.And it was working great before,almost a year,and it's a brick after this morning update.And the problem is that this phone is on corporate account,so replacement will take a while.And i need my phone working now.
UPD.
Now it's recognizing PC36IMG.ZIP but i'm getting "Main Version older, update fail" error
UPD2
I tried Amon-RA recovery,after zip check it returns me to main HBOOT screen. When im using fast.boot it's giving me FAILED <remote:signature verify fail> error
UPD3 I also tried a Windows tool to restore it and it's giving me a Error [140]: Bootloader version error?
