Why is that oppo f1s is rebooting again and again after 2nd rooting?

This is not the right place to ask root questions, as this is not related to fixing a device. Rooting is something that modifies the phone beyond its original intended design. It would be better to ask someone on xda-developers.com

u have to use advance oppo tool to flash new software . while restarting again and again you have to plug data cable ha press volume up at the same time. wait until ut finish done

You only need to do Flashing with original firmware bro.

you should try to flash new stock rom

You can repair your hp Android phone by using a flashing tool on your PC, and it can be done alone

Maybe you need to flashing a new firmware

it's very easy, just flash your ''hp '''Android''''' and finish. But that requires a lot of time. And you can search for fflashing tutorials on Google

just hard reset it. if you dont know how?

long press power button to switch it off. i mean long press until it will be off

next long press power button and volume down together until it will show the options . im tired typing bro. just search it in google. thanks to me :)
