[LG Optimus 4X HD] narkos:
hi ,

i've installed CM 10.1 on my p880 but I made the error to try upgrade to CM 10.3 .:).. all work fine but after a reboot i lost my imei number and so I can't use the phone .:confused:

I've tried to restore the previous ROM but it still don't work ... :o

So i tried to install the original rom and i put the phone in download mode ( vol down + usb cable ). Now i can't exit from this mode

( if i start my phon i can see lg logo and then "S/W Upgrade Please wait while upgrading....").

I tried with LG Flash Tool and with KDZ_UPDATE ... but always it stop at 10% ....

this is the LG Flash Tool log :
