bootloop after battery removed (LT5)

Firstly : my note get its usb outlet broken

So I can't charge it neither send data trhough the usb


I can't use Odin


I'm on the latest LT5 stock rom, never flashed any mod (none to date)

I've installed this rom with Mobile Odin 3 days ago, with no problem at all



Yet, I just take out the battery (after having turned off the phone) and set another one


And my phone became to bootloop..

So I entered the recovery mode (which is not a fully custom recovery, there was not Nandroid backup mode...)
After a cache wipe : still bootlooping

So i've done a Factory Reset / full wipe and the phone restarted normally


But I loss all my data :(



What to do ? I don't want this to happen again...


sorry for bad english
