i have tried installing older version of twrp through fastboot and twrp as well but it says flashing successfull but when i reboot to recovery still there is twrp3.1 i flashed twrp3.0 version
also i tried flashing more things like product and version through fastboot but it says remote command not allowed
so here is final status
fastboot not flashing anything everytime it gives error of remote command not allowed except in case of recovery it succesfully flashes recovery but actually still there is twrp 3.1
twrp is doing nothing everytime gives error of vendor not mount, product not mount(invalid argumnt)
and also twrp flashing recoveries successfully but in actual there is nothing flashed
so i just have fastboot and twrp 3.1
