To trellogavros (or whatever)

First you must edit this line in your build.prop file (/system/buiild.prop) first copy the file out to sdcard anywhere would do then editing on the copied build.prop because I think it will not successfully edit the file build.prop "in-situ" after (due to some rooting problems on our firmware)finishing the editing only then you copy it back to the original location and you MUST SET THE PERMISSION and OWNERSHIP RIGHT (permission rw-r-r / ownership root:root) or your device would not boot up!! CAREFUL!!.

FIND and EDIT these lines

ro.com.android.dataroaming=true ( change to = false)

ril.function.dataonly=1          (change to =0)

wifi.supplicant_scan_interval=180 (change to 360 double the delay in scanning rate for wifi )

then ADD these lines to the build.prop (if you are upto it)

hw.nophone=true

hw.hasdata=false ( careful if later you want to use a 3/4G dongle you have to change this to= true)

persist.backgrounddata.enable=false

pm.sleep_mode=1

ro.ril.disable.power.collapse=0

ro.comfig.hw_fast=dormancy=1

ro.config.hw_quickpoweron=true

Test to see the battery consumption IF you are still not satisfied then do this next thing;

Go into /system/priv-app/  rename the Telephone.apk to (.Telephone.apk) put a dot in front the name and TelephoneProvider.apk also. Android will ignore any file with a dot "." in front of its name.

Since this is your main concern to want to disable modem/opinions-on-teclast-p90hdlephone ( I have the same model as yours without 3G but my battery last about 4 days in sleep mode only with the build.prop lines, I dont disable the Telephone services apps because sometimes I need to use them.

Thank you so much !!!

I will try it today !! You are awesome.

In order not to cause any errors I have prepared a CWM flashable zip to DISABLE the "ril" and "telephony" functions. You just flash thro CWM the attached file to your device. This is for KitKat M9Pro build #407 (latest) version. (Dont flash this on other models and build version) If anybody want to use the modified build for other models they will have to manually edit it into their own build.prop

Thank you for your offer !

I flashed successfully the file. However, going to Mobile settings I saw that the modem power check is still on. Is this a fake toggle or something and the whole module is disabled now or I failed ?

Thank you anyway !!

This my status everyday even with the modem ticked (enabled it seems) my build.prop is different than yours you just flashed  where all telephony service and data service is OFF whereas mine is ALL ON. You can see that there is no data (modem) running, it only shows the screen consuming power
