Reboot when "initializing apps" 3/4 times - now stuck on android animation

last night my N5 battery ran out, tried to turn on but he was dead when load and switch off.

I left my N5 charging(off), all night

this morning my n5 boots into "optimizing apps", but stops when reach around 15/20 apps and reboot (3 or 4 times)...

Now, only keeps in android animation .
I can see my data in TWRP, battery %...

I wipe cache/dalvik... nothing
I reflash the kernel (ElementalX 6.17), still nothing
ROM Xtrafactory(M) 6.1....

Any ideas?

Now i'm doing a manual Backup before delete some data and doing TWRP backup...
PS: I think sometimes not switch on if N5 is not connected via USB / Charger, but when i'm in twrp or in bootloop i can disconnect and connect without problems

Thanks in advance
