Hey Guys, I have a P30 Pro that is not doing any loud speaker sound (so no audible ring sound, music, youtube sound, call on loud speaker), I tried replacing the loudspeaker module but it didn’t work (I will try ordering another loudspeaker to try again, don’t know if the first was working), also tried ordering the daughterboard (with the CHIP) as it looks like it has some kind of filter for the audio right under the conector under the armor (or am I wrong?) but the board came without the armor and anything soldered there.
Any advice on what to test, the audio signal come by the big flat cable? Maybe trying to replace it too?
Already done software reset and even downgrade using huawei software.
Don’t know what else I can try to fix it.
This thing is not a backup battery, it is the vibration motor / crystal, my TF700 was "vibrating" for long periods of time, I teared it down, removed it, turned it on again and the all the vibration was gone (even those that were ok, like moving from sound to vibration).
