Root [updated] Root T-Mobile LG L9 (P769)

Okay, I have been at this all day, so I'm just going to break this down for you guys:

*I am a beginner, but I have a little experience (if this makes any sense).*

Goal - root phone, remove pre-installed bloatware, and download and use the free WiFi tether (that requires the phone to be rooted, of course). [Side note] If there are any custom ROMs available for my device (the LG Optimus L9 [T-Mobile prepaid]) then I may try those, too, but I'm cool with the phone as it is; I just need to tether my 4G to do homework on my computer.

Now, my device automatically installed its drivers onto my Windows 8 computer after connecting it and selecting the "LG mode", so I have that down pat, I believe. I have also downloaded the RunMe_L9.txt file, opened it, saved as ".bat" (literally just .bat; nothing else), and ran the file as an administrator, but all I get is a bunch of "path cannot be found" followed by "press any key to continue", ending with "after your phone reboots, you will be rooted. Enjoy." The problem is: my phone didn't reboot, I am still not rooted, and I'm certainly NOT enjoying it.

So, I'm thinking it isn't working because I don't have that Root and Restore file downloaded and extracted, but it just seems null at this point since I'll only be opening the RunMe file, right? Also, if that's not the case, how am I supposed to download the required files with NO internet? I downloaded them on my phone and transferred them to my computer, but, for some odd reason, the Root and Restore file isn't something I can "extract" and/or "unpack". So, what am I to do? Does anyone have any suggestions? Please respond as soon as possible, but at your earliest convenience.

Thanks in advance,
D.

This is the same message I am getting, too. What are we doing wrong? I know someone has the answer!

all you really risk is a minor waste of time. if it doesn't work, it does absolutely nothing to the phone.
Just making sure. I'll give this a shot.

EDIT: Root achieved! Thank you all. How might I go about deleting T-Mobile crapware? On my triumph I flashed CM9 right after I rooted and installed recovery, so I never had to learn how.

EDIT 2: nvm link2sd has an uninstall option. All who are rooted give this a try:

It made a modest difference for me.

alright, go into settings, about phone, software information, the software version should read something like p76910g. if it's anything before 10g, you should be able to root it.

Okay, it's showing as P76910e. What do I do from here? In fact, can anyone with the exact steps (with the exact software version) even attest to rooting their phone with this process? If so, can you please give me a detailed step-by-step run-down of how exactly to do it? I really, really need to utilize the Free WiFi Tether (for root) app so I can get my classwork done by the 30th!

Remember, I have fulfilled all of these prerequisites, so I am going to need either a new method or someone needs to explain what it is I am doing wrong by detailing exactly how it is supposed to go.

Thanks in advance,
D

*Edit* IT WORKS!
I guess the problem was that when I downloaded the prerequisite files from my phone and then transferred them to my computer, it was incomplete in some way. I was able to extract and run them appropriately when connected to my neighbor's Wi-Fi (shh). Thanks, guys!

Thanks for all your help mjb1994. It did not update but I do not get the ota update promts anymore. When I tryed update after backing up the root it gave me an error about google something. I realized that I had to probably unfreeze all google stuff(which stilled showed frozen with titanium pro during supposed unroot) and tryed to update through the phone. My phone said it was up to date and is oddly still on 10e. The update prompts that shwed up every 30 min have not shown up almost a day later. I am happy with this so thanks!

I was able to keep my root after doing the OTA update to 10g, all I did was before I updated installed voodoo root keeper, backup my root with it, then updated to 10g, after the update I went back in with voodoo and chose to restore root then VOILA i am now rooted on 10g with my p769

I wonder what I'm doing wrong then...
I am rooted and my root is backed up on voodoo ota root keeper, but, yesterday, when trying to restart and install the update, I was presented with an upside down android with a red triangle hovering above him.

I did some scouring online to see if anyone else had this issue and I found nothing. I did find that it's people with other phones were having similar issues, though, and it is/was because they didn't have a system/custom recovery. I don't even know how to access the recovery (boot into it), nor do I know how to obtain the update again.

I'm currently running v10e, and this version doesn't allow me to tether my 4G (meaning I have no internet access on my laptop, and everything I have to do online has to be done from my phone--including homework [which sucks]). The v10g update resolves this issue, but I can't access it!

Does anyone know what I should do?

I stupidly hit the update button before reading this thread didnt have voodo installed and no more root access. any other work around? I've been seaching my a## off and nothing. I woldnt have to root if they didn't take away the capability to run files from sd. Well thats a lie, I'd probably root anyway. lol
