hmm ok I have to say right off I've never used bolt browser
that is very odd that you don't have access to the native browser.
I want to recommend that you re-install the OS but there may be a way to fix this without doing that let me research but first a few questions:
1 Do you have access to a computer?
2 Is it possible for you to hook your phone up and use Desktop manager?
hmmm... Have you removed anything from the java folder on your computer?
