Real success here, thank you very much
)
I play onto S5 / SM-G900FZKAXEF / KOTH49H.G900FXXU1ANE2 / PhilZ philz_touch_6.57.8-klte.
Abolutely no pb with that excellent work. Just think to go to extSdCard with S5 cause each bckp take 5,5 Gb !!!! It'll full your Internal SD to keep 2 version or more ; extSdCard has been build for this kind of cases...
Also added a Tasker pop-up announce msg pop-up + little beep saying that the phone will reboot in recovery mode for bckp in 120 seconds. It permits to stop it if you're not sleeping some Sat night
I also created a widget to STOP the process, juste placed nearby the one that launch. It would be easy to perform a question "Go/No go ?" to the user via Tasker, especialy for the widget variant...
Next, I think about a confirmation mail, that would be elaborated onto the PhilZ, text droped onto a folder + an init.d script to send it with the log + MD5, when the phone reboot normaly.
The Init.d effect can be gain using
https://play.google.com/store/apps/details?id=com.androguide.universal.init.d as I do not manage to activate init.d onto my rooted stock ROM.
PIN asked at restart seems to be going well with Secure Settings associated with Tasker. I'll give a try (I use PIN + biodigit) and will probably report my results here.
Last, Tasker could detect it's USB connected to your computer, and flush the /backup/* to your home hard drive, juste in case.
Thank you again
