[jmpmjmpm]

any chanc of updating this for new nokia's and older ones like 5210?

[lsalentes]

any explanation on 3310 and 6210?? :-?

[Scorpion47]

Hi sergo_zmeia can you send me complete explanation of pcb layout that you posted to my email add, i needed it thank you very much
for a big help to me :-)

[seny85]

Hiiii.......... sergo_zmeia plz can u send it to me to my mail which u have posted .i m thankful to u

[Flatphone]

explanation coming..

Where is the explanation for the 6210 pictures? I'm new here and I may have missed it somewhere. I need to figure out where the chip is that holds the phone numbers and messages on the phone and remove this chip and solder it onto another 6210 with the vain hope of getting my phone numbers back.
You may be wondering what happened to the phone......
It was run over by a 38 tonne truck!

Ok you can stop laughing now!

To be honest my trusty 6210 survived amazingly well considering, Ok so the screen broke, the aerial exploded, the on/off swich has gone.... but with a lick of paint she'll be as good as new...... or maybe not!

[rampage200ph]

What is its labelled number on the Nokia 3310 diagram shown above in this thread for the 32KHz crystal. I want to replace the part but I am failing to identify it on my pcb. Just help me identify it on the ladelled diagram posted on this thread. If not labelled try to use the diagram to explain me the location on the component on a 3310 PCB.

[electrophoretic]

number 19

[jr3620sp]

can you post a pcb diagram of a 3620 or any 3600 phone

[electrophoretic]

i dont like those kind of posts... can you post pics of this or that... please outline your problems and i will see what i have for you in my collection :P the whole point of this forum is to present problems and solutions...

[iphonefans]

I was able to convert DVD and video to iPhone using Cucusoft iPhone Video Converter Suite software I found on http://www.welldownload.com/dvd-to-iphon.html So far, I'm really impressed with how easy it is to use and how effectively it got the job done.
