I have found a workaround to enter in recovery.
a)Turn off device
c)We enter in bootloader mode, with volumeup key we select the "recovery" and press power
d)Device reboot to twrp
The basic process of installing TWRP on every phone is to boot into TWRP itself first so TWRP could overwite the recovery partition and replace the stock Android recovery with TWRP itself.
Boot into bootloader / fastboot mode
Make sure that your device's boot loader is unlocked. If not, please follow this tutorial on forum.xda-developers....
