i9100 no imei, repair EFS not working :(

[KaBLooMz]

Hello,

I have i9100 no IMEI. These the things I tried.

1) root, install s2 repair from market - not working

2) efs backup, delete efs folder, reboot to new efs folder, copy imei folder and settings back over - not working

So obvious efs is bad so

3) root on Gingerbread, use Samsung Tool 12.3 repair efs, imei. Next use Samsung Tool 12.1 repair efs, imei. Then once again use 12.3 - not working. Phone now shows imei 0000000000 but still not working

4) use Samsung Tool 13.7, repair efs, imei. - after 100% not done. Cannot find Samsung Modem.

I have 6 pieces like this, none working. Very unlikely hardware problem.

Please help thanks...
