Resposta para "My phone wont turn back on"This happened to my LG TRIBUTE HD for Boost Mobile (9/17). No one could figure out why after buying new battery. Ended up buying another device. Same model. After a week of having new phone, I inserted new sim card on old device & it powered up. So put orig sim back in old device & it started right up and worked. The new sim still works in new device. Could you please explain why that occurred? What did putting a new sim in old device do? I mean how did it start functioning again?
