For whatever reasons, I do not see any pictures but I do not think the problem is what generates the red light - either you have red light or you do not. See my file on the fibre optic loop jumper that allows one to bypass certain parts of the system such as the Bluetooth module. That link is just below but at the bottom of this post is a link to all my Infotainment system files. Most have between five hundred and thousand views so some may have found them helpful.

Regardless, I do not have any better ideas than what you have already attempted. It seems to me that you have done all the normal fixes, yet nothing works.
It may be that you will just have to wait it out. It has been my experience that for no known reason, one morning upon startup, all works again. My guess is that there has been a software glitch and over time, the glitch has worked its way out of the software.
Do not be afraid to do the hard reset over and over. Nothing will break or burn up.
For the most part, what a hard reset does is force the system to reboot, and over time, the hiccups in the software work their way thru the system and are flushed out.
In other words, what I am saying is that everything still works, nothing is broken, it is a software glitch and that takes times to get a good reload.

Hard Reset Instructions
In brief, to start the hard-reset process, open the hood but close all doors and let your 3 go to sleep - no radio display etc and no key in the ignition. This will take a couple of minutes and do not open any doors until the reset is completed. (I find that it is often a good idea to have the driver’s door window rolled down and the key in one’s pocket whenever fooling about the vehicle.)
Also, when I play with a car battery, I remove any rings I have from my fingers, also my watch.
Have the car keys in your pocket.
Disconnect the ground battery terminal from the main starting battery.
Disconnect the positive battery terminal from the main starting battery.
The reason for this order is if a wrench or loose battery cable ends grounds to the body, no arcing or other bad things happen.
(I assume that you only have one battery in your 3. If not, disconnect the others as well and leave them disconnected until after all is done.) I have the Traxide dual battery system installed.
Connect the negative cable end to the positive cable end. (
NOT to the battery.) To do this, you will need a short length, (a foot or so), of light gauge, (14 to 18 gauge AWG, insulated stranded copper), wire to span between the battery cable ends as there is not enough slack in the positive and negative battery cables for the ends to be able to touch each other.
Hold all together for about a minute or more, (suggest at least two minutes), as you are discharging memory modules within the engine computer and elsewhere. Then it is suggested you then just let all sit disconnected for say ten minutes, (minimum five minutes), prior to commencing to put the battery cable ends back on the battery posts per the following order.
Reattach positive terminal to the main starting battery positive post.
Reattach negative terminal to the main starting battery negative post.
Start engine and hopefully none or at least fewer warning lights and the radio when turned on plays music rather than being silent.
Reset time on the radio - note that the station presets are still there as not everything is erased. Nothing much else needs resetting either.
You can also now connect up the other batteries if you have a multiple battery setup.
