I have TECNO Camon CX Air and I wanted to port another ROM for my phone and I downloaded XOS ROM from:-
Code:

https://techboxlab.com/xos-rom-v2-2-for-mt6737m-kernel-3-18-35/

and it is The ROM of Infinix Hot 4 Pro and the phone is MT6737M so it is similar to my phones chipset and having kernel 3.18.35+[NOUGAT] ROM.

I ported the ROM Successfully and booted up on my phone with all the available features worked perfectly except FINGERPRINT.

When I try to enter fingerprint it says "Fingerprint hardware not found" and "Enrollment not completed" error. I tried to fix the error by searching on the web but this don't helped me to solve the problem.

I am also read the fix article at:-
Code:

https://techboxlab.com/fix-fingerprint-bug-in-mediatek-roms/

But if you read the guide it says extract the classes.dex from framework.jar using winrar from both port and base ROM but on both of my Stock/Base and Port ROM's firmware.jar there is no such file only there is META-INF.

Is there a mis location between the guide and the ROM's structure?

If there is please Help me!

MY PHONE IS:-

BRAND:-TECNO

MODEL:-Camon CX Air

CHIPSET:-MT6737M

ANDROID:-BASE ROM= 7.0(N) PORT ROM= 7.0(N)

RAM:-2GB

PLEASE HELP ME IF YOU KNOW THE PROBLEM I WANT TO GET IT BACK TO WORK MY FINGERPRINT BECAUSE THE PORTED ROM IS VERY NICE UI, I DON'T WANT TO GET BACK TO THE ORIGINAL ROM.


WHEN I CAN I WILL POST THE FLASHING GUIDE AND THE ROM ON THE FORUM! SO YOU CAN TRY IT OUT!

THANK YOU!

some phones have only meta-inf just like yours while others have class.dex within. 
there's no 'mis location' in his guide, it only means that his guide word for word will not work for you

no idea really, you have to continue your research
i only pointed the above out cause in two of my phones, one has the dex file while the other doesn't. 
so that post might be valid just for those who have dex within their framework.jar

Now fingerprint hardware not found error fixed! I edit build.prop code for fingerprint and com.finprt......from
Fingerprint d and gx fp from bin and the otheretc permission but now when I tried to input my fingerprint it has no response when I touch my fingerprint sensor at the back of my phone just stays like on the screenshot.

I used the guide @

http://tricktrackbd.blogspot.com/2018/02...e.html?m=1

and

https://forum.xda-developers.com/android...55933/amp/


And also the fingerprint menu disappeared from setting I used the app from the launcher drawer to go to fingerprint[Image: df909480562e82f329e8a15e8c3c9c91.jpg][Image: d1573e619950afd08258053e28b5c7ca.jpg][Image: df003983e131b63e8708ce11cae1f573.jpg]

I can't use the guide from the link you are given, because my phones ROM Architecture doesn't have classes .dex on the framework just only there is META-INF.
