Big problem
Hi! i have a Lg c660 and i'm very sad for this. I have been rooted and then installed ROM MANAGER to make back-up. I changed the backup name, and then i clicked ok. my phone has restarted and no started to make back-up, only LG logo appear on display. I tried emergency mode with kdz but i received error, probably was not correct ROM, I tried to restart the phone, i pull out battery and usb cable and then the phone no start. I was with him at service and a guy repaired the phone with JTAG. Now, the phone rules perfectly, but is locked on fly mode. I can't unselect fly mode. the guy from service said probably is f**ked up the ESF or EFS (i don't know exactly) which include file with GSM network and parameters, Imei, and i can't use the phone to speak at him, only without sim. How can I fix this problem? The phone was bought from Italy.
I'm sorry for my bad english, is not my mother tongue.

first i tried to flash i had no problem. then i installed cyanogenmod an then deleted the launcher. So i decided to reinstall the originial firmware, i cannot succeed., i says error, this is the last line.
when reach wParam = 8, lParam = 0 the phone disconnect itself from the PC and then the phone display the battery charging animation. Finally the phone get stack boot over and over again.

02:29:57 : Smart : wParam = 8, lParam = 0
02:36:38 : Smart : wParam = 100, lParam = 6
02:36:38 : Step : Upgrade Error error code = 6
02:36:38 : ResetStartInfo() Call
02:36:38 : _DetachDLL Call
02:36:38 : _DetachDLL Call End
02:36:38 : FreeLibrary Call
02:36:38 : FreeLibrary Call End
02:36:38 : ResetStartInfo() Call End
02:36:39 : ===FINISHED===
02:48:24 : OnModelDllMsg(OnMsgFromModelDll3GQCT_PDA) delete m_pLGCyonUpdate

what do you mean?

I thought I always start in emergency mode.
well that is what i am doing.

I'm beginning to think that the cable is bad.


PROBLEM SOLVED
1-. The transfer cable driver was installed, otherwise i could not start transfer data.
2-. The problem was the other driver was not installed (no remember the name). So after successful installation KDZ want to recognize the phone and the driver that i mentioned was no installed, so is pops up error even after install the ROM.
3-. i tried to start the phone and always got stack in the LG logo over and over again .
4-. I did not know this after i downloaded all the diver from here ( search google lg c660h soporte). So i installed the error was disappeared .
5- After no error, the star up still displaying LG logo over over again, so searching i noticed that i was not doing the right hard reset. So i did it (VOL DOWN + HOME + POWER), wait for the android logo and eureka !.


Summarizing

install the proper diver.
do the hard reset.
