[Q] P769 SU binary issue, please help! - LG Optimus L9 P760, P765, P768, P769

I'm having some issues getting my LG L9 rooted. I bought the phone yesterday evening and immediately found the easy way to gain root, using the LGPwn.apk exploit. I did it last night and things were great- I could use Titanium Backup and everything. However, this morning when I went to go use TB, I was greeted with a message that said I didn't have root, and launching SuperSU gives me the "There is no SU binary installed, and SuperSU cannot install it" popup.
I've tried a few things over and over now to get root back, from uninstalling and reinstalling SuperSU and LGPwn.apk, trying restore again and again, even factory resetting the phone. Nothing has worked- every time I try to use SuperSU I get the same message.
I've owned half a dozen Android phones and have never had such an issue as with this phone, and all I really care about is getting rid of the bloatware since I don't feel like taking on the bootloader right now. Does anyone have any advice? I'd very much appreciate it. Thanks.

Uninstall Superuser then turn your phone off. Take out the battery and wait for like 20 seconds. Then place the battery back in and turn the phone on. Let it load up and run a new fresh download of the LGPwin.apk. Once you hit restore just leave it alone. The phone should restart automatically for you. After it reboots download the SuperSU and install. If everything goes well look in the settings and place the SuperSU app in the system folder. Then download busybox and install before you do anything else. I use this one but a lot of people choose this one; your choice. Good Luck!!!

Thank you for taking the time to make these suggestions, but it still didn't seem to work.
I was coming off a fresh factory reset (though it still boots up with the 20f update), took out the battery for a minute, downloaded a new LGPwn.apk from jcase's original post, and did a restore. However, like in all previous tries, the phone doesn't automatically reboot after restore, as you said it should. It just shows the screen saying that the restore finished and needs a manual reboot.
Installed SuperSU and got the same message again, no SU binary.

This should get it working, when you use the LGPwn.apk to root, don't take your time and read all the instructions. Run through the root process fast (don't read just do) try this a couple of times. Another thing, use a root browser to check out the /system/xbin (and /system/bin) and see if "su" is in there. ROM Toolbox lite has a nice root browser. Don't worry you can get into the /system folder without root (but you can't access data).

I've tried restoring fast, slow, and in between, always the same result. su is in my /system/xbin but not in my /system/bin.

Also, if someone could point me in the direction of how to get this phone back to it's real original everything, that'd be great, seeing as how a hard reset/factory reset only gives the phone a clean slate while keeping all system updates (like 20f). I know I've come across something similar involving non-rooted flashing in the dozens upon dozens of forum threads I've searched in the last 24 hours, but can't seem to find it now. If this root method worked yesterday as soon as I brought the phone home, maybe it'll work if I can get the phone back to the exact same state? Thanks.

I agree with Kuma. . take your time and why don't you download a root checker while your at it. For some reason I had a little trouble with the root program too. It rooted my phone then it said I didn't have root so I just clsoed all my rooted apps, restarted my phone and did the restore binary again. I think I was hitting the ok button when it said restore complete. This time I let it reboot itself and I was fine. But I loaded superuser first and titanium backup, root explorer, terminal, link2sd and once I saw those were running fine I installed superSU and it deleted superuser and then I placed superSU onto the system in the setting section. Ok I'm rambling. . .just keep trying for some reason there's something going on and the only thing that I can think of is that you are already rooted but it's just not working properly.

It you have su in /system/xbin you have root. What are the permissions for su. It should be 644.

That's what I'd think, but its apparently not true here. Also, su is currently 755, or -rwxr-xr-x, and Titanium is telling me this is the su it's trying to use.

Download a busybox installer from Play Store and use it to update/install your busybox in /system/xbin, then reboot. This may fix the root issue.

Also, trying to update binary with Superuser fails when it tries gain root.

1. uninstall superuser
2. uninstall busybox
3. reboot
4. Check for root
5. turn off the phone then reboot
6. Relax
Maybe you're looking at it all wrong. There's something that you did wrong or the download was a bad one. Just re-download the app and try again. But let the app do it's thing and once you have root install superSU (I like that one because you can make it a system app with one touch).

Busybox wont even open, just like SuperSU.

Same issue, won't open Busybox.

Try disabling lookout security if that helps.

Nope, same results.
What's most interesting is that everything I read says that after running LGPwn and doing the restore, the phone should restart on it's own. When it does finish the restore, all I get is this screen that expects me to restart the phone myself:
{

"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

I hoped you don't hit the button. You are suppose to just leave it alone and it will boot by itself.
