upgraded a samsung s3 through the OTA update, ever since the mobile network has gone south, phone does have an imei anymore with no baseband, which has made it reject all sim cards
any idea on how to fix this?
appreciate all ur help

You'll need to reflash the stock backup via Odin, this should restore your baseband and set IMEI to 0 (some networks tend to work normally even with this). You'll then need EFS pro restore your EFS if you want your original IMEI back.

For MTK users experiencing such, you can see

2, I have d efs pro but how is it possible to restore what I didn't backup.

1. Just ensure you flash a stock ROM for your exact model
2. Get your baseband back first and see if IMEI is 0, you can then begin to manually edit an existing EFS backup
3. NVRAM is for MTK (i posted a video for that). EFS is for your phone type
