Can u show me how you do that (DC/AC) method to me? I am interested.

@ Edwins C,

Why the huge text size? I know akingsm was asking here. I was trying to encourage proper habits by not replying to his query in this thread which is for network problems. I request you not to use such huge fonts as we are not blind and its a waste of a page as with such huge fonts only a few posts will be seen.

@Gabsi,

Please start a new thread if u can't find the reply to ur query in old posts. This thread is for network problems only.

I have found the solution for using volte meter to measure TX/Rx without Tx/Rx measuring points. To use voltemeter, fix the ground and touch +ve point at all Tx/Rx measuring points. you will find different values of ampare at different points,which can be noted with ok kit. Enjoyeee...

Ashiq Rasoul · 02-20-2005, 07:53

I also got the solution for my 3310,2100 which no one has told me at my previous post.

make sure that you flashed same sw as the hardware - if 1100b make sure sw ver is the same - otherwise if network was ok before you write flash - try writting a PM(but make sure you have good one - without IMEI field ).

Hi all,

I have a 3510, originally from TIM (Italy), unlocked, and I'm trying to use it on Orange UK (1800MHz). Once yesterday I saw good signal, but normally I get no network at all(zero signal, "no network coverage" when trying to make a call). Yesterday I tried some friends' SIM cards: it didn't work on T-Mobile (also 1800MHz), and it was ok with strong signal on Vodafone and O2 (both 900MHz).
Trying to select network manually with Orange SIM, it sees all 4 networks, normally hangs for ages trying to connect to Orange but immediately says "no access" trying Vodafone or O2. Not always so, however: sometimes Orange responds faster or Vodafone takes ages. Very intermittent behaviour...
Any ideas how to troubleshoot and fix this?

Thanks!

P.S.: The phone was dropped on ice+snow, probably got wet; changed cracked LCD, but everything else looks fine inside.

[Rod] · 02-20-2005, 14:49

regards
