SOURCE: stuck on boot loader,phone code sig error v3i r47a_g_08_d8_89r''

I Charged the battery up using another motorola phone,and then I did a software upgrade, and this has fixed the problem.The phone is working great now,all photos or videos were saved.
What i think caused this error is that the phone was doing an upgrade and then I got a message at the same time,I think these clashed some how and prevented the upgrade from completing,hense causing an error on the boot loader.

Hope I helped
