I did something so stupid I'm almost kind of proud of it. I rooted my LG Optimus T (Froyo) using Gingerbreak, cleaned out a bunch of stuff, and accidentally deleted the home screen launcher. No big, I'll just install a new one... but I have a chicken and egg problem now, that requires debug mode to get out of. I can't just open settings on my phone to set debug mode. And the phone only starts up in safe mode.

So the tl;dr is this: I need to force my phone into debug mode via USB, in safe mode. If I can't do this, I will have to buy a new phone. Please help me!

With a proper Recovery (e.g. ClockworkMod) in place, and having made a proper Nandroid Backup, you should be able to restore that and start over. Or did you forget that backup? –  Izzy Jul 26 '12 at 21:21
    
Besides (I wasn't sure first), if your CWM is recent, it should also offer you a root shell (see here -- so you could copy the Launcher to your SD-Card on your computer, insert it to your Optimus, launch CWM, and push the app to the system partition. –  Izzy Jul 26 '12 at 21:30
    
I had a Titanium Backup but it got damaged somehow. Anyway, I can't get to the screen to restore from backup either. I do not have ClockworkMod. –  betherwisser Jul 26 '12 at 23:22
    
I see. Then the best you could probably do is to follow Michaels advice (which was what I had in mind in case you had no backup and no custom recovery, call it a "last ressort"). And make sure to include the last mentioned step, and install a custom recovery. CWM is the most used, some prefer Ammon Ra (I go with CWM). –  Izzy Jul 27 '12 at 6:12

The easiest way to recover your phone is to flash the original factory firmware on it.

After much searching I found a thread at XDA which explains how to do this for the LG Optimus series phones including the P509 (yours).

You can obtain the original firmware by following these directions (substituting P509 which you have for P500).

After you recover, remember that the first thing you should do after rooting a phone is to install a custom recovery (usually Clockworkmod Recovery) as this gives you access to tools to manage situations like this.

I have seen that thread before. The links to country codes and such are all dead. :( –  betherwisser Jul 27 '12 at 19:49
