  1. Hi,
    I have a problem, I rooted my phone and installed TWRP. It booted to my stock OS , I went back to TWRP to clear cache but I actually clicked on format data and typed yes.

    Now my phone constantly boots into TWRP, there is no OS installed, for this I downloaded Freedom OS and tried to flash the zip, it installs and reboots my system but I end up rebooting back into TWRP. I checked the sd card folder throught TWRP but I see no android files there. The internal storage is empty. I even tried to flash the 4.5.5 OTA but its the same. The phone bootloops back into TWRP.

    I am unsure what to do now. Can someone please guide me ?

    I also have the one plus recovery image file downloaded. I am not a pro at rooting but I can try following instructions.I use a mac and have the adb and fastboot drivers with me.

  2. Don’t Worry. First, install the latest TWRP from the link that i gave.

    After that Download, the FULL ROM file of OXygren OS 4.5.5 and install the same by following method.
