Make the bin files on your own (without CWM injection). You can find the how to in my Noob Thread. First make a Factory reset then, flash with Smartflash, boot it up, make another factory reset (best would be including SD cart), just to really get rid of all the data, which might tell them, that your phone has been rooted and I think that's basically it Just make sure, there is nothing on your SD card anymore, as well and you cannot reboot to recovery anymore and there are nomore superuser rights on your phone.

I think there's no need for leaving the SD Card inside the phone..
They don't need your SD Card inside your phone in order to repair it.

easier, flash it with smartflashtool and restore your imei

hey guys i have instlled a stock rom thru smart flash.... jst 1 more question

hw to b sure dat dere wil be no trace of rootin nd to chk dat d rom i hav installed is nt rooted??

after smartflash you can be sure will be ok if you flash stock rom from your carrier

wenever i do factory reset after initial LG logo the below attached image comes up (jst d background of the image no text) nd after that lg animation.....

is it ok??

If it's only the text, it should be fine. Just download quickboot and try to reboot to recovery. If it works, you need to flash again, if not, everything is fine
