Sudden No service message on iPhone 2G

[RandmTask]

Hi,

Have an iPhone running 1.1.1 that has been working fine unlocked/jailbroken for the last year.

Last week however it came up with 'No service' after I turned off an alarm i set.

Also, the sound stopped working and wifi stopped working.

I tried resetting network settings and that didnt work

Then I updated ituned to 8.0.1 and installed 2.1 firmware then QuickPWN'd the phone to jailbreak again (didnt unlock again, as I believe that it doesnt need to be down and I didnt have the 2 bootloaders it was asking for)

Now the sound and wifi work but I still have the 'No Service' or zero bars reception

iTunes at some stage said the SIM was invalid but was able to successfully update to 2.1/PWN/restore the device

Any ideas of what could be wrong or how to fix this? or how to test if the phone has a hardware problem?

cheers

^^Yes you DO need to "unlock" again.

It isnt necessary depending on what firmware you have and are going too....but going from 1.1.1 - 2.1, it updates baseband, etc, and you will have to unlock again.

So, thats why you have no service, you are running a locked phone.

I have the exact same problem, and pretty much same symptoms. Any help is greatly appreciated, thanks!


Update: Just thought i'd put this out there; i updated to 2.2 to see if it would make a difference (first gen iphones retain unlock though loose everything else). Well, basically, the service is back, though intermittently is lost.

well i had that problem before but mine was in firmware 1.1.4. what i did to fix up the solution was try to restore the whole thing do not restore all your settings....

hopes this helps
