Whether to Restore the "Android ID"

Hey Guys,
After flashing a Custom ROM, i went to restore all my apps from Titanium backup but it gave me the warning that my device's 'Android ID' has been changed and gave me the options to restore the old one/ask later/keep the current one.
Does anyone know the best way to proceed?
Yes, hit restore, it will reboot, job done

Is it necessary to restore Android ID? I always ignore it and haven't notice any problem yet.

I think it applies to root protected apps ie banking etc, so if you don't have these I don't think you will get problems

Sorry but it is not possible to restore files from a full-wiped S3 since the data partition is for multiple reasons no longer an additional fat32 partition but piggybacking in the system's ext4.
However I want to point out that a full-wipe is only done on the stock recovery, not when using Cwm.

S3 or 9100? Thats Two different phones there!
Check your imei and report back.
Sent from my GT-I9300 using xda app-developers app
Have you tried going into mobile networks settings and ensure your APN (Access Point Names) are set correctly? In rare cases, these may have been resetted during the full wipe and flash.
If you dont know what are your carrier's APN settings, try googling for them.

Network not registered!!

Hey guys
So I'm not getting any service at the moment even though my IEMI and serial number haven't changed and they dint start with 00. I was running CM10.2 when I had signal. Then I decided to flash a different rom. After doing so I lost my signal to I reverted back to the 10.2CM rom I was using and now I don't have any signal. I've looked at other posts on this and I've tried many things but I can't see where it what the problem is caused by and how to fix it

First you read the faqs and guides and learn how to.
I9300 does not have locked bootloader.
Second don't hijack threads with a totally different question .

IMEI begins with 0049? changed your APN settings yet?
IMEI number is fine starts with 35. APN settings is for the Internet. I can't send or receive calls as well as text message. Mobile data dosent work. Wifi does. As for the apn settings I can't seem to find the proper EE one

try to restore your very first buck up then try to flash the rom you want
You need to downgrade back to your old rom for that old efs backup of yours to work

Your serial no is corrupted but your imei is fine. Nothing got to do with Apn.
Go to Settings>About Device>Status look for serial number
Go get yourself a patched modem. Problem solved.

Well if you are afraid then you should just drop that idea of flashing a rom..
But AFAIK if you read everything you should know and do evrything corrrectly then you would have no problem..
