LG G Stylo 1 frozen on MetroPCs boot screen

[ammire m]

can anyone here help me with a issue i'm having? so first of all i was using my LG G Stylo and it turned died on me, so i plugged it in on charge and tried to turn it on right after only to be greeted to a frozen MetroPcs logo. this isn't the first time this happened. last time i had just factory reset my phone a truly sad day losing all that data. Now once again it has occurred but i don't want to lose all my data and files again, not to mention the countless passwords i don't remember by heart. if anyone has any ideas, or has been through this before please reply a meaningful answer so i don't have to reset again. So far ive tried the battery remove for 30 sec and hold all 3 buttons and the method on letting it completely die then charge it too 100%.
