LG Marquee + CTMod

As fair warning, this involves rooting your phone, which voids its warranty. BUT I just completed the firmware installation on a refurb'd Marquee and it runs very smoothly now, particularly compared to the frame-droppy mess that it was before (which is sad...the phone has a 1GHz CPU in it so it should run nice and smooth even with stock firmware, but I digress).

Anyway, here's how you root/install ClockworkMod Rcovery (required to flash the ROM):

Note that you need to install msxml as well as the other stuff, otherwise the firmware downgrade won't work (the downgrade is the trickiest part of the whole process). Also, at least for my phone you'll be following the Sprint instructions, even though the branding on the phone case is Boost Mobile.

Now for the easy part: download CTMod to your SD card's root (you need a microSD card for this), reboot into CWM and apply the zip. Your phone will be factory reset in the process.

You'll need to reinstall all your apps, including any Google apps (Voice Search, Maps, GMail, etc.), but that's okay...things run faster that way.

This ROM is still Gingerbread (there are a couple devs working to make ICS/JB a reality) but, for an inexpensive refurb phone like the Marquee, that's perfectly reasonable.

  • I'll echo this sentiment. I personally find it abhorrent that stock shipments of phones are delivered so crippled and non-functional. Installing a trimmed-down, slim OS is crucial to the smooth functioning of any phone. Even the most tricked out phone will crawl if it burns cycles processing garbage. Android can run very smoothly on even the most meager of phone specs (sub 1GHz CPU, 256MB RAM) if it's running something near stock with little waste.

  • Fortunately for me, my Marquee came with ZV9 so I didn't have to downgrade. I installed CTMod a few days ago. The only problem is MMS. I can't send or receive picture messages. Is anybody else having this problem?

  • Never-mind, I fixed it. Apparently flashing CTMod also changed the MMS URL to http://mms.sprintpcs.com/ which is incorrect. You need to change it from http://mms.sprintpcs.com/ to http://mms.plspictures.com/ in LG's hidden menu in order for MMS to work. I was able to successfully send a picture message. I'm still not sure if I can receive picture messages though.

    If anyone's interested...

  • I've only rooted a couple phones and not sure what OP is referring to  "Note that you need to install msxml..."  I skipped this and ended up following the boost-specific steps in the linked guide. Just in case it saves anyone else 5 minutes which I wasted - I needed to have a microSD in the phone to install cwm.  So, put a card in and formatted just to be safe, then re-ran the cwm installer and copied over CTmod. So far so good, will update with any issues.  Cheers -

  • I'm waiting for the same phone. I've heard that some custom roms have some bugs or make things not work (e.g. the camera).  Does this have any of those issues.

  • @Matthew - The camera and everything else seem to be working fine. The only thing that gave me trouble was picture messaging.

  • After installing CTMod, my phone tells me that I'm on the Boost Mobile network.  Anyone else?  Is this a false alarm?

  • I think you installed the Boost ROM. There are 2 versions available: Boost and Sprint. Use the Sprint one, it should be easy to revert back. If the PRL settings are now messed up, you may need to temporairly go back to the rooted Sprint ZVC stock ROM, make sure the phone works fine, voice, data, sms, etc. and then flash again to the CTMod Sprint version.

    A good resource here, though I think some of the steps might not be entirely correct if I remember corectly when I tried to apply them to my phone:

  • Hey, I just ordered 2 LG Marquee that are in the mail and I just want to make sure I understand the directions as this is my very first smartphone.......

    Is the referb phone going to have the OLD stock software "ZV9" so I don't have to do all the extra steps? If so is this how to do it step by step?

    1. Download Sprint CTMOD 3.75 on computer to the desk top, is Linux  or Apple computer OK (I don't have Microsoft)?

    2.  Connect phone to computer, do I set phone to mass storage? Then drag and drop file to my phones micro SD card(I already have a 2 GB one), do I double click on it to unzip it before I drag it to phone?

    3. download ClockWorkMod onto micro SD card

    4. Open ClockWorkMOD, make a backup of stock ZV9 software, Select "install zip from sdcard", Select the CTMod.zip, Select "yes", After its finished press back, Select "reboot system now"

    5. Now I'll have the CTMOD on the ROM and it breaks MMS so I need to follow these instructions

    "After installing a custom ROM, you'll find that the MMS will "break." In other words, you won't be able to send and receive MMS anymore. Thankfully, there is a pretty simple solution to this.

    Go into your phone's dialer and type: ##data#

    Or: ##3282#

    Afterwards, you'll be taken to a special screen. Scroll down to the icon labeled, "MMSC."

    Click on "MMSC" and a dialog box will pop up and say "View" and "Edit."

    Click on "Edit."

    Then, you'll be prompted for some special number to enter in order to proceed. This number is called your MSL number. You'll need to call Ting and give them your phone number and ask them for what your MSL number is. Afterwards, come back and repeat these steps up to this point.

    After entering your MSL number, you'll be allowed to modify the URL used for picture messaging. Delete the URL (which is most likely called):

    http://mms.sprintpcs.com

    And, enter the new URL that is associated with Ting:

    http://mms.plspictures.com

    After entering that URL, you are finished. You can now return to the home screen."

     

    1. So by now I'll be completely done, can I now send and RECEIVE MMS?

     

    Thanks for your time, I appreciate it.

  • The phone you get may or may not have the OLD software. You will need to determine that when you get the phones. It may even be different on each one.  I wouldn't bother with the questions until you get your phones. Some things will become clearer when you have the phone in front of you. Read through the link from beginning to end http://androidforums.com/marquee-all-things-root/552289-root-your-updated-lg-marquee-phone-step-step.html Some of your questions will already have better and clearer explanations than you will get here. If there are things that you don't understand from reading through you should ask for clarifications in that forum. If you want second opinions by all means ask them again here.

  • Another question: have you seen any significant improvement in battery life with CTMod?  Seems sorta sucky so far with the stock gingerbread.

  • @william b - if you get the ZV9 make sure you don't check for software updates, it will save you a lot of trouble from rooting the phone.

    @Matthew Scott  - battery life seems to be better with the CTMod ROM. Plus you have choices to underclock (or overclock) the CPU and quickly turn on/off features you don't use. For my phone I bought an extended battery 3500mAh ($12-$15 on ebay), yes it makes the phone bulkier and heavier which I actually like and I get at least 2 solid days of battery, sometimes more, and I don't bother turning off wifi or cell radios when not in use, I set wifi to never sleep so I can keep GrooveIP running all the time where I have wifi.

  • I'm having a terrible time trying to get the firmware rolled back so I can root. I was almost giving up, but you make CTMod sound so good, I'm giving it another try. Here goes another 5 hours down the toilet.

  • Anyone know of a good IRC where I can ask for help with this?

  • Dunno where you can ask about it on IRC, but my guess is the part you're getting messed up on is timing the phone power-on correctly? If counting to twelve after hitting the software flash button doesn't work, try powering on right after you hit that button. That's what it took to get one of the three phones I've flashed so far to work.

    Beyond that, make sure both the flasher and Windows Enabler are run as Administrator. Also, you'll need to click the iIndows Enabler icon once (it's in the system tray/notification area) after you start it so that the icon says "On".

  • Thanks for the pointers, Ian!

     

    I've run both the flasher and the enabler as Administrator, and I've clicked the enabler in the tray.

    I didn't think it was my timing, because I've never had a problem getting into the "Software Updating" screen. I was able to get to that screen both by pressing the power button right after clicking update, and by waiting 12+ seconds. 

     

    It looks like it's in the right place, but I always get this error:

  • I have the stock ZV9, does it matter if I use Mac or Linux when downloading clockworkmod and CTmod then coping it to sdcard?

  • It does and it makes it easy to turn off radios when you don't need them. But it's no replacement for an extended battery.

  • I am using go laucher with a nice widget to turn radios on/off. But I need wifi on all the time to receive voip calls and get email notifications.

  • Yeah, I need wifi too when available. I use Llama Location Profiles to manage my settings and turn cell/wifi on/off based on where I am. At home I keep wifi on at all times with the policy to never sleep as I use Groove IP or Spare Phone with Google Voice. If wifi goes to sleep I can't get incoming phone calls. The cell radio is off while at home. When not at home, it's the other way around, the cell turns on, wifi is off, auto-sync is off (to save on mobile data). Llama has some learning curve to come up with the right rules and it took me a few days of real world testing to come up with a set of rules that work well enough.

  • Can someone help me boot into clockwork mod???

    I downloaded cwm on phone from google play store and downloaded CTMOD 3.75 from computer, extracted it to new folder, and dragged it to my phones sdcard. I tuned the phone off, held down volume button and power button, but it just takes me to factory reset options. I turned the phone back on and opened cwm app and it says the phone need to be rooted for cwm to work.

  • william b, it sounds like you didn't follow all of these steps exactly:

    I would seriously stop before you go any further. You aren't close to understanding any of this and you truly risk bricking your phone.

  • The LG Marquee I ordered from Ting has a Boost Mobile logo on the phone itself but in the notification center/system info (Android 2.3.4) it says Sprint.

    Should I be flashing the Sprint or the Boost Mobile ROM? :\
