TWRP loop on booting nokia 3? i successfully installed twrp but on twrp reboot i selected system and now on opening nokia 3 it goes to twrp.
Only twrp can be opened not the OS (normal boot) of nokia 3.

I tried flashing stock rom of nokia 3 with sp flash tools but on starting or booting phone , it will not detect nokia 3 and red and yellow bars does not appear.
so how to flash stock firmware when i am stuck boot looping in to Twrp.
Any other way if possible please describe.
As your question you install twrp recovery and did you perform wipe after that ? If not try this might work or try the following


Turn power of your phone in twrp recovery option by reboot\power off or hold the power button till it shuts down.
Now load stock rom in sp flash tool.
Now click on download button.
it will dectect your phone if your phone is power off and if battery is removable please remove it before connecting
now connect your phone with usb in one end and to other end with pc.
if it didn't dectect install the right mtk drivers.
after successful install your phone turns to stock os with stock recovery and will boot normally.


Alternative


Find custom os for your device.
move it to sd card.
flash it through twrp recovery.
then perform wipe and clean cache and boot normally.


Hope it works.
