[Q] i9300 bootloader problem will pay for assistance - Galaxy S III Q&A, Help & Troubleshooting

Hi there. I have a i9300 I am having trouble with i will try to explain.
It was stock 4.0.4 worked fine on Spanish Vodafone
then i used odin to update to a stock 4.1.1 then rooted and unlocked everything seemed to work fine.
I put in my sim that used to work fine it searches and finds the network then it registers with network then shows emergency calls only as shown
I can post screenshots
I will donate $20 via paypal to anybody who can assist me and get my phone fixed

- Did you use an unbranded ROM or the one for your specific country + carrier?
- what rooting method did you use?
- did the SIM card work in this very same device before ?

If you just want to return your phone to working state (no jb), try these steps:
-Download This and unzip to your desktop (It is the stock Vodafone Spain ICS)
-Boot to recovery, wipe data/factory reset
-Boot to Download mode
-Connect to PC and open ODIN
-Select previously unpacked file from desktop to PDA slot
-Make sure that NO pit file is selected and Re-partition is NOT ticked
-Hit start, it will flash and reboot to android

the same sim worked before and another different network worked fine too. I have not tried an unbranded rom.
Another sudgestion was that it might be something to do with the bootloader?

Hardly. If the bootloader was faulty your phone probably wouldn't even been booting.
Like it's been suggested, reflash the JB ROM for Vodafone/Spain. You can also download it from here : http://samsung-updates.com/device/?id=GT-I9300
If that doesn't work, check with the operator if there has been any block made to your IMEI.
Does that SIM card work on a different phone now? Do other SIM cards work in your phone now?

See if your imei is fine: type *#06* to phone app. It should show the same number like the sticker under your battery. If its not, you might have corrupted efs.

when i do *#06* it does not registered on network then goes back to the dialpad when i go into about in settings status and it displays my imei does that sound like a corrupt efs?

If u can't connect to your operator then ussd codes won't work.
Check mobile networks/access point names(in settings), if your apn is there and connected to mobile carrier. If everything is as it should be, then try and change your modem..xda member "upintheair" has posted a large collection of modem's in his thread..
U can backup/restore with apn manager(when u get the phone working again),its free from market.
Ps: does all other sound areas work, like notifications/music/ringtone..

The correct code is *#06# try again and see if it shows your IMEI number.

Ahh I see that I failed at the code ....
Try to go to settings -> Mobile networks -> Network operators
and select the appropriate network for your carrier
+ also try different modems as suggested
If it still fails, I dont know what next..... :S
