so i think is a matter of software!! and my warranty expired! so... i kinda expensive 2 get a new original software ... i rather buy a new phone ...

I duno what 2 do!! ... i send it to motorola service!! i w8 an answer

I got a new battery and fully charged it before using it....this has cured the issue...your battery may be the original one (mine was too) but the phone is no longer original state you bought it, it resets the battery setting inside the phone.
my suggestion is when you have a new fullt charged battery in the phone, use MSS to backup the phone settings and store for future.

Can't see that as the problem as your writing new software to run it,...but can't tell what the problem is at 87% unless i run a cable watcher... make sure you are using the right program to load the flex and make sure you tick the master clear and reset buttons
