Need help about naza m lite disgrading on original m lite  firmware from v2

By mistake I've upgraded naza m lite (which was upgraded on v2.) To 4.4 firmware
Now when I turn it on it I'll goes in self check mode n never come out

Need to degrade on m lite
BT can't disgrade with normal prosses of connecting f1 and f2 port

Pls help

hello... in self check mode it will take 2 mints.. if it take more time than power cycle your FC
and for downgrading the firmware connect F1 and F2 with servo wire and connect fc to pc and run Naza lite assistance software...
hope this info may help you

regards

For degrading it to naza lite u have to connect the f1 & f2 using a servo cable. Then open naza lite v1.00 assistance. Make sure its red coloured assistance not the black coloured one. Then click on update and get it updated to m lite firmware and then use the hack again to get it upgraded to v2 4.02.
