I've read a lot of HowTo's for flashing back to stockROM.

On two ways I had a little hope (one is this one here, see log-file above). But even phone switched of after about 90% of flashing.

I think, the main problem is, that flashing CM10 set a "new" serial number (IMEI still o.k. and original).

I see at the moment two ways to fix the problem:
(but I have at the moment only "S/W update-mode" and "fastboot")
- Is there any chance to set the serial number back to original?
- Is it possilbe to bring back CWM-Recovery to the phone?

OR

..succsessful flashing to stockROM..

thanks for help!!!!!

UPDATE:

CWM is back on phone with this tool: http://forum.xda-developers.com/show....php?t=1971014 So it was easy to bring back CM10nightly to the phone.

The main problem is still there:

HOW TO COME BACK TO STOCK ROM?!?

What I tried until now?

Try to flash on this way here (1st post) --> I seems to work fine. Flashed up to 90%, phone swiched of.. (I've read at different places, that is o.k.), no automatic reboot. When I start the phone again, it stops at the silber LG-logo. No chance to come to the LG-recovery. Flashing CWM again (http://forum.xda-developers.com/show....php?t=1971014), done all wipes (wipe data/factory reset, wipe cache, wipe dalvic cache).. Boots again only to silver LG-logo .

The other way was the LG Flashtool, but the same result !

So my phone is working with CM10 quit nice, but I've still no chance to come back to StockROM .

Flashing with KDZ-Files dont work to my phone .

Is there a chance to restore a backup of a stockrom from an other LG P720??

Can anybody help me out with this?
Is there any other idea to come back to stockrom?

Thanks for your help!!!

Please visit and feedback http://forum.xda-developers.com/show....php?t=2085344 hope new pals will find it useful.

what does the "clear phone software update registry" mean? what does it clear?

Can anyone provide live links to the kdz files. All seem to be dead
