Can't enable USB debugging, is permanently grey

Sorry for my bad english, first of all. I just bought a LG Optimus L3 and, of course, I want to root it..:).But, I can't enable USB debugging, is permanently grey......Is this a required step for root?.....please help.Thank you.
 
Can you post a screen shot of the settings/applications/development screen?
Use a screen capture app from Google Play, then use photo bucket App from the Google play. once you have the screen shot uploaded to Photo Bucket select it and hit the menu button. Select to copy the img URL. Go to this site with a browser from the market that will enable Desktop view (Dolphin HD is the one I use). Paste the screen shot img URL into the reply box making sure you have
in front of the IMG in the box. I think it can be small case img but I'm not sure.
 
All screen capture apps from Google play needs activate USB debugging. I can't do that, so I can't use Android SDK (DDMS).......other solution pls?

Anyway...there are three options.....USB debugging(permanently grey, inactivated), Stay awake and Allow mock locations.
 
hi harris, try this

1. connect phone to pc
2. see usb icon on shortcut drop down, you see message : charge only , usb storage , go to pc-software and press ok.
3. go to settings menu- press applications - press development now you can press usb debugging press ok

USB debugging options should be able to tick.
If u want to root, you can use this link

beforehand, you need to install L3 USB driver, find it from LG E400 Support: Find Manuals & Warranty Info | LG UK click the software update & drivers

After rooting, i manage to find useful application that can so called "map" internal sd folder but put the large big file in external SD
This app requires superuser access. here is the link [TOOL] DirectoryBind - move data to external_sd (GameLoft, Shadowgun etc.) ROOT req. - xda-developers

so far i am quite happy because i can move my huge offline map to external SD

For force moving application that belongs to phone memory only such as Adobe Flash Player, i use Link2SD. This also requires superuser permission and farthest only to Internal Storage, not External SD.

Your using windows right, have you installed the L3 usb drivers ...Connect L3 to pc via usb select go to pc-software and press ok, select usb debugging..run.bat file your phone should reboot in a second or two ,don't touch it even if it seems to be in a boot loop mine did that a few times,it will eventualy restart and if it worked you'll have the superuser app .. Seems a it quiet on here XDA forums has got a thread on the L3 thats updated daily.

yup ive installed the drivers that i got from LG site(windows usb driver=l3 usb drive?) if that would the case i installed it already. but why is it that after i run that file nothing changes to my phone.

well if i run my that "run.bat" on my pc there is a black box(seems commandt promt) and says press enter or any key to root your phone., and still i have the same result >.< ive tried it many times but i dont know what is really wrong., i getting headaches and starting to pissed off about this situation.. haha do you know other reasons why?. or is it the driver?. i dont anything else more about this situation. i really need help :)
 
I would check if the usb drivers are installed properly or just reinstall them and turn off anti virus software it may conflict, or try a different usb port ones on the back of the pc seem to work best, when I rooted mine I used linux on my netbook no drivers needed and it took two times for it to work so dont give up.
 
im getting same probs as Sharkeater , someone heeeelllllp , tried everything , adb drivers antivirus off etc the lot , this has to be something n nothing . my phone is on latest firmware could this be the issue ? i also trie on different pc running xp not 7 to see if this was an issue but still get same outcome ....its winding me up !!!
 
Hilly windows not working do you know anyone with a mac execute the &#8220;run.sh&#8221; instead of the "run.bat" or try a live linux

If the USB is connected to the PC in a mode other than charge only, it will be greyed out until you unplug the cable ;)

Thank you! I couldn't figure out why I couldn't enable USB debugging on a particular device, but could on others. Mystery solved!
 
Can someone help me? my lg e400 is already rooted but i want to hard reset it now, but it wont. i tried the lock button+volume down+home button but it wont do any too.

Sorry for delayed answer. This is not a problem - you really need a PC connection to enable it - but once you did it, it will stay enabled even if you are disconnected from PC.
