you don`t need a tutorial, just flash the ICS kdz over what you have.
I did this downgrade from JB to ICS and it works. Maybe your kdz wasn`t good, try to get the official one.

you should use V10K that homero shared before bro, it work like a charm

Don't work for me v10 zip.I've tried ,but i get bootloop.Now i'm on the last nightly.
Sent from my LG-P700 using xda premium

Try reflashing in emergency mode (volume up + volume down + power button).

factory
after the flash, we must do a factory reset.

cant understand
i lnow this is awkward but I didnt get it..can you please tell me in a simpler language...please

i have written a guide in android development to downgrade... just search downgrade in l7 android development u will find a thread for it

[Q] Can't flash LG Optimus L3 II

Hello!
I've spent too many hours trying to figure this out, now I'm becoming hopeless! :crying:
No matter what settings I try on the KDZ update, I always end up on this error:

10:07:19 : OnModelDllMsg(OnMsgFromModelDll-CDMA) delete m_pLGCyonUpdate
It is interesting that it says "CDMA: wParam = 100, lParam = 0", although for other people it says "3GQCT: wParam = 100, lParam = 0", even though I set it to 3GQCT, my error includes the word CDMA instead.
Also, I'd like you to tell me if that's right: "Check Phone mode = 1", shouldn't it be "2"? I turn off the phone and connect it to the PC with the "- volume" pressed down. Then a black screen appears with the words "Download Mode".
Thank you!

And BTW, if I run it as administrator, it won't even decrypt the KDZ:

13:26:21 : kdz decrypt error.

Try another rom which is compatible with your phone. Download KDZ updater from another source. You might also try flashing KDZ from another computer.
