Hello guys,I'm currently on the 4.4 version and I'm trying to downgrade my phone to 4.2.2.The NoriOS version
Why?Because I need OTG to work,also would like xposed to work too
I have tried to flash it from recovery but I get the "Installation aborted" message.
Does anybody know how to sucessfuly downgrade down?
There is already a downgrade thread here but the thread is full of offtopic and has zero revelant answers

i need a CWM recovery for my device
i found a device same as my device (coolpad/yulong f1 plus ) but with minor difference like name ,model etc
it is from the same manufacturer there are 6 version available 3 of MTK and 3 of qualcomm based chipset
i tried to flash recovery which was for f1 plus but it soft bricked my phone or something else all it was showing was bootloader mode
somehow i managed to flash stock recovery via bootloader mode using a batch program developed by cool community which was for flashing recovery on f1 plus
then i decided to port recovery by myself but there is no guide for porting recovery for qualcomm device using windows (as i don't possess linux or ubuntu os)
please help me out
