Please could you furnish me on the best software program to use on a pc for unlocking and flashing cellphone/mobile phones? If there is a software that does not require any hardware tools, please kindly tell me of it. I have browsed all over the internet only to find out that most of them require boxes of which i am not looking for something that uses a hardware box like jaf, octopus, etc. I have found out about jurassic uniandroid software/ and infinity BB5 but i don't know how the softwares work, and also some people tell me about flash files requirement which i do not know anything of at all. Please help.
