No Wifi and no carrier after Blackra1n Bootneuter
yesterday I tried after FW 3.1.2 to JB and Unlock my 2G 8GB with Blackra1n and Bootneuer. Everything went fine without any error.
Bootneuter asked me to reboot after flashing was successfully.
After the reeboot I had no Carrier and no WIFI.
If I now restart the Bootneuter, it says "couldn't communicate to comm..." and it ends. If I reboot and retry it stucks at "determinig.... setting".
I tried to downgrade with Itunes (9.02 on Windows7 HE) it stops with error 23. Also DFU mode is not working. In other Forums they say that I have damaged my board.
If yes which board is damaged? Logic Board or the communication board?
Or is there anything you would suggest me to do before sending for repair.

You need to get the direct link for an old 1.x firmware from here. Firmware - The iPhone Wiki

Once itunes detects your iphone in dfu mode it will offer only the option to restore (update will be greyed out) Shift-click restore in iTunes (option click on mac) to get the option to browse for the firmware ipsw you downloaded earlier. You may get 16xx errors during downgrade, if they come near the end of the downgrade, this is because the baseband part of the downgrade did not work. As you are planning on erasing the baseband this error can be ignored.
