Hello! Have Unlocked the bootloader after i flashed my phone from a vendor rom to a China dev rom.Now i am on Global stable 188.8.131.52(LHPMIDB)Offical rom. But now i want to install TWRP and ROOT but it´s not working. If i install TWRP will the bootloader be locked again?And what version of TRWP shall i use?? Must i have TWRP installed to install a Eu rom? I dont know how to install Eu rom weekly i cant realy find any guides to do it. Must i Flash the phone back to a China dev rom and after that install EU rom? Or how do i do it??? If i install EU rom weekly will the boot loader be locked again?
