Ok, I can add one more bug to report. Regardless of the current battery level (100% or 50%) after a while of moderate use like web surfing and for example reading mail, the battery level drops to red and the phone sounds the low battery alarm and notification banner tells me that the battery level is low. This does not affect the usage of the phone in any way and the autoshutdown does not kick in. After the work is done, and I put the phone on idle the battery level rises back to 50% or 100%, where it was before moderate usage.

I got tired of the low battery alarm so yesterday I decided to replace the new bme with the stock one and confirm that the 100%-50% battery level and the low battery alarm was connected to the new bme. I installed the stock BME with this line:

After hitting the reboot button, phone went of, but didn't reboot. I couldnt get the phone to boot or to charge. I swapped a full extra battery inside and the phone then responded to power button and booted up. The battery icon was 100% and the green led was on on when the screen was off (normally even with "full"battery after the boot, my phone show one level lower than the full battery). I then concluded that the batterylevel problem had something to do with the bme-helper files and not the bme itself, so I reverted them also back to stock:

And everything went back to normal. Have to see in the future to test only the BME replacement, if it works without the other new files.
