Hi @Pascal_A - I’ve managed to get my phone back. I’ll tell you what I did based on reading this forum and others - some may not be necessary but they worked for me.
- I couldn’t boot into TWRP; I had to backup my SD card then repurpose as portable media (it was set to be treated as internal storage). Once I had done that I could boot into TWRP
- Once in I couldn’t re-install GAppsDownloader and Xposed Modules (I read you need to reinstall these after each update)
- I used the Official TWRP App to download the latest version and flash it to recovery
- I installed the image and then rebooted back into TWRP (I read that you need to reboot to recovery for the update to take) and am now on v.-3.2.3-0
5, I was then able to reinstall GAppsdownloader and Xposed Module through TWRP
Having done all that my phone is working perfectly again - it charges when on, battery life is back up to over 24 hours and there are no heating issues with the processor. As a matter of fact it is all running cooler than it has ever done.
Don’t give up - I hope this helps you too.
