    If this works, you are my hero and I will bow to you.

    This doesn’t work on the m323. It’s bootloader is strapped and recovery mode is inaccessible by any conventional hacking means. No one in the android rooting society has been able to touch it, although unbranded LG Optimus L70s may be able to be rooted this way. Just not the M323 (Metro PCS)

    Hey Peter, I recently purchased the Metro Pcs LG optimus L70 (MS323)…I wanted to root my phone. I am a rookie when it comes to rooting phones or tablets, I looked over ur instructions on how to do it and was getting ready to start, when I saw that someone else said there was a problem doing it the way u explained doing it..I was wondering if u could answer a few questions for me, and possibly help me root my phone. Thanks

    So does this really work for the ms323?
    if so, it seems some steps are missing. Every other forum I’ve visited said that the ms323 is not yet root able.

  • meow

    Or just use towelroot

  • Raw

    Towelroot worked for my lg optimus l70 ms323 on the metro pcs network.

  • Dznutts

    Towelroot works on L70 ms323 for metro PCS

  • Jay R

    Yes I agree…. Towelroot worked for me also on kitkat 4.4 on cricket

    como paso un archivo con ext2 fsd tool a la sd?

    Towelroot didn’t work for me. I followed Peter’s advice but got stuck in a few areas and finally got stopped after using the adb shell to reboot my device. For those of you who found Peter’s instructions a lil bit confusing, Here are the steps in a bit clearer fashion:

    1-Download everything in the links he mentioned
    2-Install the LG drivers
    3-install and run the Minitool Partition Wizard Free application. Hopefully your SD card will show up at the bottom of the Minitool App window, if not, try a different SD Card reader (your phone should NOT be connected to your computer during this time)
    4-In the Minitool application, right-click on the icon representing your SD card and click on Delete all Partitions (or Delete if only “Delete” appears)
    5-Minitool will show this as a pending operation in the left tree menu. It will not act until you click the “Apply” checkmark in the top menu (If you actually wanted to save something on this disc, select the “Discard” (red “X”) and use a different SD Card
    6-Your card will be erased and unpartitioned. Right click on the information line BELOW the SD Card icon again and choose “Create”
    7-Change File System to Ext2 or Ext3.
    8-Change Create As to Primary
    9-Resize the slider widget under Size And Location to at least 3MB (you will eventually copy the file to this partition and it is roughly 1.23MB – 5MB is ample room) and click OK
    10-Right click on the information line 2 lines BELOW the SD Card icon and choose “Create” (the 1st line should be the partition you just created)
    11-Give it a label if you wish (though it is not necessary. It is just to keep track of which is which). Change the drive letter to None. Click OK
    12-Click the “Apply” checkmark in the top menu to commit changes.
    13-Click Yes to proceed. You will now see progress bars indicating that the partitions are being created
    14-(hopefully no errors) When this is done, you now need to run the Ext2Fsd tool.
    15- When Ext2Fsd opens, You should see a list of disks and their partitions (if not, either press the F5 button or go to Tools > Reload and Refresh)
    16-Your screen should look similar to the one Peter posted above with one Linux partition displayed (it may say Ext2 or Ext3 or RAW under the File System column, none of this will affect you)
    17-Right-click on the Linux partition and choose Change Drive letter (this helps windows to identify it as though it is a Windows drive).
    18-Choose Add..
    19-Choose a letter that is not in use (I normally choose either U: or X:)
    20-Ensure that there is a checkmark in the midle option or the option that reads “Automatic Mount via MountMgr…” and click OK
    21-Wait for the drive letter to appear in the blank field then click Done
    22-Right-click on the Linux partition again and choose Service Management.
    23-Remove the checkmark on “Mount all volumes in read-only mode”
    24-Place checkmark next to Enable writing support for ext3 volumes then click Apply.
    25- You may get a “Current settings will be overwritten message. Accept it (click Yes)
    26-Now open Explorer (or whatever you use to see all of your drives in your file system). You should see your disk. You can now copy the file onto the disk
    27-Now the ugly part, on the newer LG70s, KitKat does not show Settings > Applications > Developer options, Instead you have to go to Settings > General > About Phone > Software Information and tap Build Number a few times until a message stating that “you are taps away from becoming a developer” appears. Keep tapping. Once that finishes, you can
    go back to Settings > General and you will see Developer options
    28-The USB Debugging will probably be greyed out. You have to turn it off, then turn it back on using the on/off toggle above. You’ll get a message asking you if it is ok to turn the settings on. Choose Yes.
    29-Click the checkmark for USB debugging
    30-Whew! Now let’s actually connect the phone to the computer using a USB cable
    40-If you haven’t already, unpack and install (well anyway, unpack…) the ADB tools to a folder somewhere (I suggest making a folder in System32)
    41-Open a command prompt and navigate to the folder that you unpacked ADB in (if you unpacked it in the System32 folder, just open the command prompt and goto step 42)
    42-type: adb devices – this will produce a prompt that proves the PC is communicating with your phone (debugging MUST be on in order for this to work)
    43-Once connectivity is verified, type: adb shell – this will temporarily switch over to a linux based command prompt (you will see the command prompt change to something like ‘shell@w5’ or something
    44-just type the words: reboot recovery. Your phone will automatically reboot and try to enter recovery mode

    Unfortunately, mine briefly shows the little Android recovery screen and then quickly boots back into my normal phone image sooo… Me Stuck! Hopefully someone will find a fix and add to this thread…

    I have a question, that may or may not pertain to this. I have an LG Optimus L70 and just recently, the Camera says Can’t connect to camera. Do you know how to fix this?
