6.1.3 custom firmware -no signal
 

Have iphone 4 modem baseband 01.59.00, got shsh files for 4.3.5 and 6.1.3.
Sn0wbreeze or redsn0w dont support 4.3.5 so it had to be 6.1.3 after errors on handset in opening app's.
Got shsh from ifaith, made custom firmware 6.1.3 stitched shsh with sn0wbreeze and flashed it with itunes 11.05, booted with redsn0w installed p0sixspwn and ultrasn0w.
All is good but only 1 bar signal then searching, there must be other with same issue.
Is there a fix?

Regards.

Update.
Done the same with ifaith, after finding out that it preserves the baseband to 01.59.00, but it does exactly the same 1 bar signal?????????

Any idea's.....
