Yes it will work for t mobile. Just make sure you download the appropriate files for your model. You said you get stuck at 4? If you mean step for that's just copying all the files out of that particular folder listed

I'm still stuck im really not sure why i cant get this correct. I'm not sure but if anyone is willing to assist with this i would be willing to compensate that person please DM me if you can help thanks.

I know this thread is a little old, but i had the same problem after rooting my T-Mobile Flex. I'm telling you, the guide to restore stock firmware DOES 100% work. The problem is that it's not clear on what state your phone must be in. I had to manually enter Download Mode in order to get the thing working. I have been reading that some people were able to fully restore their phone by using the LG Suite program, which can be found on LG's official support page. Make sure your computer actually "registers" your phone being connected to it by installing the appropriate drivers.

The UNROOT
If you wanna unroot your device, why so ever, the easiest way is to use Unlock Root (Link above) open it, connect your phone via USB, enable Debugging Mode and click unroot. If you wanna unroot it, e.g. to be able to send it back to LG on warranty, better use the method below, to unbrick your device with R&D tool.
Because like this, you will get back an unrooted device, which has also been hardresetted. So LG will hardly/never get a clue, that it has ever been rooted.
Dont forget to format your SD card as well

That's from my how to, but I think I should correct this. Use Smartflashtool and flash the latest version available for you. Do a factory reset from within settings menu and everything should be fine

Your problem is not from rooting. You may have inadvertently messed up something in your system partition. Try to lg flash tool back to stock.

⬆⬆⬆⬆ Rooting cannot break knock on. I would try
1. Make sure it's on and toggle it either way
2. Factory reset after making a LG backup and dragging that file over to your computer. Then reset and drag the file back To the LGbackup folder on your phone. Restore from backup and the whole process shouldn't take more than 5min and you're phone will be exactly the way you had it setup still.

I'd LOVE to know how to fix this issue on AT&T 950 variant. That's the only thing keeping me from flashing back to 4.2.2 so I can install custom recovery. If you know how to fix it when I downgrade from KK to JB I'd be forever grateful.

Like justinwidebody suggested dial 3845#*959# then click "Settings" then "Update Touch Firmware"
or in Geners case I think you have to dial 3845#*950#

Actually the hidden menu on Sprint does not have the option to fix it. The work around is go into the general section and download my Sprint unlock Rom which is a att Rom. Then use the att dialer code and get into the hidden menu. Then go into recovery and run a back up. You will have knock on again.

I have flashed the LS995 Rom that you provided to return to stock, and yet the knock on is not working. I dont know why.
Yes, the ATT Rom that you provided is great, it can repair the Knock by access the dialer code.
After I fix the knock on, and I use TWRP backup to restore System, Data, Cache, EFS, Boot, but the knock on is gone again on Sprint Rom.
Do you have any guide to restore back the knock?Or I perform a wrong way?
Or perhaps there's a way just to get the touch firmware from AT&T or AT&T Hidden menu LoL and install it to Sprint LS995 Rom.
I would appreciate your help.

[Q] Help me about the update!!!

Hi everybody, I'm a new user. I just bought a new G2 phone of Verizon and I don't know how to update it up to 4.4.2. The seller told me that I could use the flashtool to update it, but I can image to do that. I've read a topic that guides us to do that but it's not so clear.
It's here: http://forum.xda-developers.com/showthread.php?t=2699123&page=37
So can anybody do me a favour by letting me know the concrete process? Do we need to connect the phone to the PC to run the adb shell or we can do it on our phones? How we open the adb shell on our phones?
And one more thing, I have to mention about the "auto rotate". Does anyone have a problem with it after update?
In settings at the bottom there's an option for system update. I didn't use a computer for the update, all OTA! As soon as I got the phone and got my wifi set up, a pop-up came up on my phone alerting me to an update. Both mine and my wife's...

When changing the drivers in zadig did you put the phone in dl mode? Also try using windows 7 or older. The restore never failed on me, not even once.

No offense, but if you can't download a file off the Internet:
A) you shouldn't be rooting and deleting stuff
B) i'm not going to have the patience to help you.
Sorry, but downloading a zip file from the Internet is really, really basic stuff.
