[DEV] Z5 Kernel issues & related stuff + fix(es)

The following is all on stock (out of the box), unrooted kernel + ROM

Seriously Sony, what is wrong with the other half of this octa-core CPU ?

The following hints at some issues with Bluetooth headphones. Call or sound output related issues could happen (?)

Anyone had issues with stability at the end of calling ? ( https://talk.sonymobile.com/t5/Kerne...s/td-p/1022774 what phone model is this ? )

Random Shut downs, Freezes, Download Mode and other stuff

About a week ago, I updated my CyanodgenMod 12.1 rom and, suddenly, my note began acting nuts!

It started to freeze and randomly shut down with no warning. I wouldn't be able to power it back on immediately either. I'd have to remove the battery and wait at least 30 seconds before putting it back in and starting it.

I tried downgrading to back to the previous version but, it continued to do same thing even on the previous one.

I used Odin to go back to latest Touchwiz stock firmware and the firmware did it too. I've tried almost everything and now whenever I try use Odin to go back to the previous firmware before 5.1.1 December, Odin fails and gives me this message:

<OSM> Please wait..
<OSM> Checking MD5 finished Sucessfully..

<OSM> All threads completed. (succeed 0 / failed 1)

My bootloader says this:

UDC Start
sw REV Check Fail: [aboot] Fused 4 > Binary 3
[1] eMMc write fail: aboot

Any suggestions on what to do or what's wrong?
