[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Oliy:
I have since discovered that my IMEI has been blocked. This phone was bought off eBay in January but apparently the block was only placed on August 7th. I'm gutted, I'm really hoping this can be resolved or that I am covered by insurance.

Hi everyone,

I'd greatly appreciate any help anyone can give me. Here is what happened:

About 2 weeks ago I upgraded radio from 1.38 to 1.50, which worked and everything was fine.

Last week I went on holiday to a little place on the beach, where signal has normally been a problem. Not so this time, I had plenty of signal and was talking and texting fine.

On Tuesday it worked all morning and then in the afternoon the signal dropped off and it said "no service". I cycled the phone radio a few times and rebooted the phone, all to no avail. I concluded that the local cell tower had a fault and that I wasn't in range of another.

On Wednesday we took a trip and, as I expected, a few miles down the road my phone picked up signal again, consistent with the faulty cell tower hypothesis. I recieved a load of texts that had been waiting for me, made a few calls and everything was fine. When we got back to where we were staying, the signal held - I presumed the fault had been fixed.

Later that evening the signal dropped out again as before. I assumed that perhaps the fault hadn't been sufficiently fixed in the cell tower, so while annoying I presumed when I got to a different area the signal would come back like it did before.

However, it didn't. We came home on Friday and it hasn't picked up a signal, just says "no service". If I manually search for networks it finds O2 (as well as all the others) and I can select it, but it still says "no service".

I plugged in a T-Mobile sim, and it found signal immediately, BUT I cannot send/recieve calls or texts, people calling me hear a strange problem about it being unable to connect their call, and text message delivery reports give the same (not the message that one gets if the phone is switched off) - so it is obviously on the network but something is stopping it using the network - when I try and make a call I instantly get those four beeps which indicate the call has ended.

I then phoned O2 and said I think my SIM is dead, and they agreed and are sending me a new one. However, I then tried my old O2 sim again and got a brief signal, but still the same problem as the T-Mo sim - cannot send/recieve calls/texts/anything.

My O2 sim now says no service, although I have tried it in another phone and it works fine.

Since then I have re-flashed 1.38, hard reset the OS (Sleuth's v3) and flashed the O2 WM6 official rom with 1.47, all making no difference. I've tried forcing 2G and 3G and particular frequencies (it usually says it cannot apply these band settings, but after several reboots I sometimes manage to change it).

So, in summary:

Signal is very intermittent and usually says "no service".

Even when I do have signal, I cannot send/recieve calls/texts.

My O2 sim definitely works.

I have tried radios 1.50, 1.38 and 1.47 to no avail.

I have hard reset the ROM (Sleuth's v3) and flashed the O2 official ROM to no avail.

Desperate for help! Many thanks
