Sorry for my English it is not so good.
I've done something stupid. I've wiped my system in TWRP mode.
So I've tried to reboot but it stucks on boot screen.
I think that my whole operating system is lost.
So I want to ask if there is a chance to recover my phone. Thanks in advance.
Phone model: HTC M7 running Android 4.4.4
Note : My phone can not connect to pc.
Conditions for flashing RUU
Bootloader LOCKED or RELOCKED when S-ON (This condition can be ignored when S-OFF)
RUU Software version must be EQUAL or HIGHER than the device version (This condition can be ignored when S-OFF)
MID match of RUU and the device (This condition can be ignored when S-OFF and SuperCID)
CID match of RUU and device (This condition can be ignored when S-OFF and SuperCID)
HTC Sync Manager drivers installed (You may install Sync Manager to obtain the drivers and then remove Sync Manager again, because its an extremely annoying, stupid software, that interferes with the RUU.exe and breaks the update process – the drivers install separately from the package and will stay when you remove Sync Manager – you only need those drivers).
Prerequisites
Download HTC Sync Manager from here
Boot in bootloader then connect the USB cable, you should see FASTBOOT USB
Open a terminal and tape fastboot reboot RUU, the device should reboot in RUU mode (Dark screen)
Double click the RUU downloaded previously and wait the end of the process.
PS: First, relock the bootloader otherwise the flashing won't succeed:
Boot in Fastboot mode then tape fastboot oem lock
