Bold 9000 doesn't turn back on

Hi there! I'm very new to Berries, and a couple of weeks ago I got my first second-hand Bold 9000. I've been reading these forums ever since :rotfl:

After installing some apps and doing a battery pull in order to free some memory, my device got stuck at startup, as shown in the picture below.

Tried removing the battery, inserting it while plugged in to usb. I've read other threads [here and in some other forums] about whether it's the battery or the device itself, but I've seen it's a kind of common issue. Even tried to remove the battery for any amount of time, but to no avail. :(
I got no other battery/charger available for now.

What can I do? Thanks in advance.

Warm greetings from Guatemala.
