I did clean flash before too, and it was not working same as you.done clean flash, but getting stock in setup on WIFI screen, tried flash without debloater as well, same issue. Setup doesnt go past wifi screen for me.
Dirty flash from stable h2os should do the trick.
All using modified TWRP.
Kindly try the following :
1) Factory wipe<br />
2) Flash H2OS latest stable<br />
2) Flash latest nano opengapps<br />
3) Reboot and ensure everything is working<br />
4) Reboot to recovery again<br />
5) Flash H2OS latest beta (without wiping at all)<br />
6) Flash latest nano opengapps<br />
7) Wipe Dalvik and Cache (optional I think)<br />
8) Reboot and ensure everything is working<br />
