When i turn on my Samsung gt E2120 it says phone freezed how do you remove this?

turn on your freezed gt-e2120, after its says phone freezed dont turn it off, turn the phone around and take the cover off with the phone still on. now take the battery out. there is a sticker all around the phone all you have to do is take off the Samsung sticker so your left with plane sliver battery with no logos. now insert the battery without any SIM inside, turn the phone on it should be working, no turn off put your desired SIM inside then turn back on. fixed.

OPTIONAL:

you can put the sticker back on after you have fixed it
