[foosoomin]

Hi all,

Yesterday night i encounter "phone is encrypted" after relocking my bootloader, because i modified the 7.1.1 operating system

I tried to enter into TWRP recovery through turning on HTC download mode screen, but failed


Therefore i wanna ask, can i flash HTC Recovery back into my phone, to replace the TWRP ?
