content: So i pulled out my old beaten up Nokia because there's a very special phone number in that i'd like to recover.Screen is smashed and the keyboard is missing, on top of all that i have no memory of how to use it.Maybe you guys have suggestions on how to convince this humble beast of giving up it's secrets ?Ps: it does power up and make noises.

content: Quote from: Refrigerator on October 09, 2016, 06:21:27 pmDoes it still have a SIM card? Those phones offered an option to store the address book in the SIM card, so you can just plug that into any other phone and see if there is something on it.Another option is PC software, but that very much depends on a specific model of the phone, so you'll have to search yourself. You may also need some goofy data-cable with a proprietary connector. Those were truly horrific times...

content: Quote from: ataradov on October 09, 2016, 07:00:53 pmIt's just a mini-b cable and i tried hooking it up but from what i know it asks questions on the phone on what to do with the PC interface and it also need some PC software from Nokia to even read the damn thing, what a pain in the arse.Would help if the screen wasn't cracked.So my next best bet is to try pop in a sim card.Quote from: Kilrah on October 09, 2016, 07:02:15 pmGood idea, i'll see if i can find any.

( ahhh memories, Select > left > select > down > down > down > select > select )If i'm not mistaken the number transfer should be - Unlock > down > down (x8)>select, but i might be wrong.It's kinda like the konami code.The SIM itself is long gone.Oh and i also checked if there are any for sale and apparently around here they're quite the collectible, only found one locally for 45$.

content: If the phone asks what connection type to select once the cable is connected, then it's easy. Basically 3 tries with up/down selection + confirm. If it is set to permanent setting which is not PC/Nokia suite, then you need to dig deeper in the menu. In that case just get crappiest $3 display from ebay IMO, or you will need reference phone to dig in menu on both phones simultaneously.

content: You could also pull the phone apart and read out the contents of the memory. They weren't encrypted so it was quite easy to recover all kinds of data provided you had the tools.

content: Quote from: TwoOfFive on December 25, 2016, 11:14:00 pmCertainly no, you will get "Contact service" on the screen (dead phone) best case. And what a good idea swapping BGA is when phone have just a broken screen which you can get for a few busks (chinese crap of course, but works).

content: Quote from: wraper on December 25, 2016, 11:24:09 pmI would not be going anywhere near the main board with heat.If any swapping was being done, I'd be going with displays and keypads loooooong before any desoldering was even considered.

So if button assembly is lost, it's not an issue, you can press on the dome sheet directly. If even dome sheet is removed from the PCB, you can just short the contacts with something, like tweezers.
