    Ok, this phone does not unbrick the same way as most other LG phones will.

    You will need:
    Drivers installed- https://www.box.com/shared/32c5t7fj2w8xcwr0krjo
    LG Mach Firmware: LS860ZV7_08.S7_08.P25010.tot Alternative: http://www.filedropper.com/ls860zv708s708p25010
    LG Flash Tool (read the Readme!): https://app.box.com/s/ua760vn52db4ainj92hb
    LG Mach DLL for LG Flash Tool: http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=CT109871648442116484421/

    This guide is intended for windows users. There is no way to unbrick this phone unless you are on windows due to the software being used for flashing only made for windows.

    1. Put your LG Mach in download mode:
      While powered off, hold volume up + volume down + power
    2. Connect a trustworthy USB cable
    3. Open up LG Flash Tool
    4. Tick "Select Manual Mode"
    5. The DLL selected is called "LGLS860_20130220_LGFLASHv141.dll", find where you extracted that to
    6. Select Add, choose the tot file you downloaded.
    7. Press ok.
    8. Read instructions here on how to configure the COM Port and flash: LG Flash Tool - Free - no need B2B User/Pass - GSM-Forum

    Thanks! The download worked.
    Now I just need to get past the "Tot File Open Error" in LG Flash Tool.

    That might be my bad... :eek: the tot is only 100 something megabytes which I dont think would be the right size...

    Is there a way to convert a cab to a tot? I still have the 509mb cab file that I downloaded from LG.

    Yes, but its a very detailed process and the tot is in the cab.

    I used ArcConverter to convert the 509mb cab to dz, and got the same file error.

    Nope. Wrong file format. Cab is not supposed to be a dz, if anything a dz would be inside the cab.

    My Mach is working again!!! Thanks, man!!
    Here's the play-by-play:
    1. I downloaded the tot file from uploaded.net/f/ibssdg. The file size is 978mb, and, unless you're a premium member of Uploaded.net, it will take anywhere from 2 to 4 hours to download this file. Also, it took 3 attempts to download the entire file. The first try downloaded a 1/3 of the file, the next a little more, bingo on the 3rd attempt.
    2. At first, LG Flash Tool failed in about 2 seconds. The second try took maybe 5 minutes, tops, to go from 'wow, this might work', to around 85%.
    3. At around 85% the progress bar stalled, but in a few seconds the phone rebooted to an LG screen, then Sprint screen, then Home screen.
    4. Then the progress bar went up to 98%, and I got the all-too-familiar "Download Failed" message, apparently because the connection reset itself. Supposedly there were "500s" left to complete the download. Didn't matter cos...
    5. The phone was ready for activation. It will take a few minutes for the phone to reach the network, but it's worth a few minutes of anxiety to finally have a working Mach again.

    thanks for this - I guess I need to paypal you some $$

    or else let me troubleshoot your car issue! (Japanese car specialist)

    PS - can you give me a list of apps that commonly cause this soft-bricking on LG Mach, because the way I soft-bricked it was removing what seemed to be useless apps after I rooted the phone - someone said removing crap like google play music etc. would mess it up? - I also removed Sprint ID, Sprint Zone and Google Play Movies and Google Play Magazines and perhaps a couple of others!

    by the way, will this phone ever have an unlocked bootloader or custom ROMs?

    Do not delete google play videos.

    A bypassed bootloader may happen if djrbliss decides to port loki to this phone. The only thing he needs is your aboot partition. If you have no idea how to use adb, I suggest someone that knows how to use it attempts. Is there a dev anywhere at all that has this phone?
     
  20. LexusGuru

    can you delete google play books, google play magazines, or google play music?

    I know of no dev in the world with this phone, and I have searched pretty hard!

    I do use adb a fair amount to transfer files and/or install non-google play store software

    I have an extra LG Mach for development use if you have a recommendation on who could utilize it for the greater good! - I am a 5-row qwerty junky or I wouldn't care about these phones!


    Also - I need some advice/help:

    when I soft-bricked the phone, I lost the 3G flashing for PagePlus, I would like to restore this flashing using same phone number etc. so I can get the use of the rest of this month of my Page Plus prepaid card! (not to mention makes some calls and have a working phone again :rolleyes: ) - right now I get "thank you for calling Verizon Wireless, we will connect you to an external operator to make a call"

    the good news is, I do have a legal, registered, bought and paid for, latest version of CDMA Workshop version 3.9.0, how could I get the correct settings for an LG Mach on Page Plus with 3G for Birmingham, AL (Verizon SID 00113) to reflash it it using CDMA Workshop?

    Is everything programmed correctly for page plus? Are you on PagePlus's PRL??

    Idk of any devs that would be interested in that phone at all..sorry.
     
  22. LexusGuru

    maybe it is noob question, but

    setting up the phone on PagePlus is what I need the help with, like if you had an LG Mach and you had the latest and greatest CDMA Workshop, and you have a current PagePlus account, I have all the tools, but the CDMA Workshop learning curve is a little steep - I just need to know what are the PagePlus settings are I need to set in CDMA Workshop, if that makes sense, and I need to end up with 3G service, which I had with PagePlus before it bricked - CDMA Workshop has about 5000 different settings!

    PS - I am still wondering if it is safe to delete google play books, google play magazines, or google play music?

    Yes you can delete all that. There's another guy on pageplus with the LG motion. He can probably help you. I don't have time to find him, I g2g to church.

    something else you cannot safely delete - anything that says LG Home or Home - lol
