LG Marquee - Easy Root (LG-LS855)

I've recently found an extremely easy way to root my LG Marquee:

 


1. In Settings > Applications > Enable 'Unknown Sources'

2. Download app attached to this post to your phone, and install it, or scan QR code to download:

3. Run the app, select SuperSU instead of Superuser (Superuser fails to work at times), then click 'Gimli' option, then it should say 'Root successful' or similar. Then if root successful, open SuperSU app, it'll ask you to 'update binaries', so let it do that update; once SuperSU binary update is done restart the phone; after that you can install Rom Manager, and do your thing!

  1. (Optional, but recommended) Install custom ROM - CTMod (the best for this phone yet). First, make sure you have Rom Manager (Clockwork Mod or similar) installed, and custom recovery flashed, then download CTMod for Boost Mobile or Sprint®* (both reported to work fine) to your sdcard, then open Rom Manager and make it install 'ROM from sdcard', and don't forget to do a full backup before doing that!

Download CTMod here (official page):

For more information, see source of this root app (Framaroot) on XDA developers (note that Framaroot works for other phones as well, for list of compatible devices see list via link below):

(Note: so far only versions 1.3 and 1.4.1 of the rooting app are known to work)

 

Good luck!!! Post here if it worked for you!

  • Worked for me! Thanks for posting this; I looked into it when I got the Marquee and what I found had a ton of steps! This couldn't be any easier.

  • That's great, Dave! That's exactly the reason I didn't try rooting before myself - way to many steps, did not worth it.

    Also, if you want to go all cool on your LG Marquee, I would suggest installing this ROM (CTMod 3.80):

    It worked like a breeze for me. I practically got brand new phone in the pocket, with virtually no lag, that's how amazing this ROM feels.

  • Yeah I've heard nothing but good things about ctmod rom. Thanks for the link; I'm going to give it a shot Friday!

  • What version were you running before you rooted using this method? The old ZV9 that it comes shipped with or the updated version ZVC?

  • @The UltimateG, I fully updated my Marquee after I got it, so, I guess I was running ZVC (or whatever latest) back then.

  • I was running the ZVC update as well... that's the beauty of this method; no downgrading and all that craziness! Worked great for me. I just recently installed the CTmod rom and the phone is a ton smoother!

  • I have an LG Marquee from Ting sitting on my doorstep when I get home...if I understand correctly, this root method will work on even the latest firmware?

     

    Also, what version of Android is CTMod running off of? is it 2.3? I really want a 4.x ROM...I see CyanogenMod 10.0 is 'stable' on this device, but stable is subjective to them as they don't test everything extensively on every device.

  • @Joey, yes that's correct, it worked for whatever latest firmware was there at the end of 2012. Which is most probably what you've got. CTMod is 2.3 unfortunately - mainly because there is simply no good drivers to support Android 4.x. But be confident, CTMod will make it feel like 100% different device - a device worth much more than what LG Marque initially was.

    Also I've checked CyanogenMod site and didn't find no indication of whether it is stable in this device. In the past there used to be some semi-functioning ports to LG Marquee, did not worth it. CTMod is extremely stable and quick, totally awesome.

  • Got the phone and installed CTMod 3.8. It's incredible how smooth this phone is now...it was laggy right out of the box with stock firmware.

    The Cyanogenmod version I was looking at was for the P970 Optimus Black. Basically the same phone but for other carriers. It doesn't work on the LG Marquee.

    I found a great way to make this phone look like stock Ice Cream Sandwich / Android 4.0. After installing CTMod, flash this ICS theme with Clockworkmod (click Beta 3): http://androidforums.com/marquee-all-things-root/549496-theme-ctmod3-6-et16s-ics-theme-holo-beta3-alpha4-updated-5-22-2012-a.html

    Then, install "Holo Launcher" and "Holo Locker" from the Play Store for free and tweak the settings to how you want your drawer, home screen etc visualized:

    https://play.google.com/store/apps/details?id=com.mobint.hololauncher

    https://play.google.com/store/apps/details?id=com.mobint.locker

    Note: everything looks great with the ICS theme, but the CTMod settings force closes. There's not many options in that one setting pane, but you can long press on your home screen and add shortcut > action > CTMod settings to get quick access to it. The only useful option I found ws to change the font color of the time in the status bar to be holo blue.

     

    Quadrant benchmark was 1850. On my similarly-spec'd Nexus S running stock 4.1.1, I got 1100. And the CTMod Marquee isn't even overclocked by default!! It feels like it's worth double now with my ICS theme mods.

  • Do you install the Sprint or Boost version of CT Mod?

  • Also, after using this root method, I attempt to test root and it seems to hang.  Tried installing a recovery as well and it just hangs when it attempts to try superuser.

     

    Any suggestions?

  • @Rory, honestly I don't remember already, I think I did 'Boost Mobile' one, since my LG Marque is labeled with Boost Mobile branding. All in all do full backup first, before installing any ROM's.

    As for root method, make sure you're using Framaroot v.1.3 (later versions didn't work for me), and when running Framaroot select SuperSU instead of Superuser. I believe superuser failed for me as well. Then if root successful, open SuperSU and let it update it's binaries, than restart and you can install Rom Manager, and do your thing. I hope that helps!

  • I have a marquee from Ting labeled "boost mobile" I did the framaroot using version 1.4.1 and it seemed to work fine.  I used SuperSU and Gimli, rebooted.  Installed and ran root checker  https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck and it showed I was rooted.  Was able to install Clock work mod recovery and a new rom no problem.  Just sharing my experience.  Thanks

  • @Mike, that's great! So version 1.4.1 works, good to know. If you installed something other than CTMod, let us know. It's interesting to compare other ROMs.

  • It was CTMod I installed and it seems pretty killer as far as features, speed and performance goes.  It is funny I used to use the old long way (load zv9 sprint rom, root phone,etc...)slow and painful way to do this then found framaroot and was like wow can it really be that simple!

  • Yepp, Framaroot is awesome, quite a painkiller from stock experience. There been roots before that, but they were way too complicated, so I ignored them. I used stock Sprint ROM for few months, than I installed one of the Launchers which speeded some things a bit, but was only a half measure. Then - CTMod. If only there would be drivers for Marquee's hardware so that they could bump it up to Android 4+. My biggest and only issue with CTMod and LG Marquee in general - extremely slow camera performance - point, click, then hold it steady and in 3-5 seconds you may get a descent shot, lol))) Makes me sooo mad at times!

  • My marquee is a secondary / backup phone for me so I don't notice the camera issue.  Just a suggestion have you tried other camera apps?  I don't know if it will help but I am pretty sure there are other apps out there.  Just a thought.  Thanks

  • Well, honestly - no, not really))) Well except 'Silent Camera' which produces pics quickly but with pretty poor quality, compared to built-in camera app. So I don't really consider Silent Camera as a full replacement for stock one. However I haven't look hard enough - and perhaps I should...

  • My experience: I had a Sprint phone purchased on eBay, so I installed the Sprint rom. From what I understand, even a Boost LG Marquee can install the Sprint rom because the only difference is some Boost-specific apps, which Ting doesn't use anyway. Try for yourself but make a NAND backup first! Framaroot 1.3 worked for me, but ONLY after I selected SuperSU instead of Superuser, and the Gimli method.

     

    The camera is awfully slow. In fact I'm upgrading ASAP and selling this phone. With the root, custom rom that's faster, and ICS/JB theming I've done to it, I bet I can get more than I bought it for!

  • @Joey S - I am confident your statement about sprint roms are correct.  My phone is labeled Boost as stated above and when I did the old root method you had to load the zv9 sprint rom onto the phone and mine functioned fine.  So as far as stock roms go the sprint one worked for me.  I think if you load the boost rom it will break a some stuff on your phone.  Not 100% sure but I think the cell settings for boost are different than sprint and I believe ting uses the sprint settings.  I could be off base on this one but I know the sprint stock zv9 rom works on my boost labeled phone.  Thanks

  • I just checked mine and CTMod 3.80 is running the ZVC firmware. I think that's newer than ZV9 as I see instructions on downgrading to root, but the method above worked fine on ZVC!

    And just to confirm, the camera still sucks on ZVC so there might not even be a reason to upgrade.

  • Nice.  Yes ZVC is the latest.  But the old slow way made you roll back to zv9....what a pain.  Also Joey I see you are in the ting army, just out of curiosity are you having MMS issues?

  • No issues Mike...what issue are you having? sending/receiving? Did you change your MMSC URL? If so and you're still having issues, remember that MMS goes over the data network to send/receive, so if you are on wifi and keep data off with a toggle or something, you'll need to turn it on before sending or downloading an MMS.

     

    If you need help finding the MMSC URL I can look for those instructions, but I think they were here on the BYOD page.

  • Thanks for the suggestion but I am working good. I was wondering if you were caught up in the MMS mess the marquees are having. I have been working with brad on the issue. Thanks!

  • Ah didn't know there was a current issue. I only use MMS sparingly.

  • And also consider yourself lucky for not falling victim to it. Now I know why you are not having the issue....you have a sprint branded marquee. You mind hoping over to the army area to the marquee thread?

  • Hey, it's my first time rooting and I want to install CTMod, but I'm a little nervous. I rooted just fine, installed the ROM Manager, backed up my current ROM, used Titanium Backup in addition to that and I'm trying to find my efs folder in the system files to back up my IMEI (I'm vaguely following the steps here: http://www.droidviews.com/things-to-do-before-and-after-installing-a-rom-troubleshooter/ ) I've tried using Root Explorer with root permissions, but I can't find the folder. Is there such a folder on Boost Marquees, and what is its file path? All the Googling I'm doing about the issue is just pointing me to apps and tricks that work with Galaxy lineage phones, nothing that seems right for Marquees.

  • Hi Megan, nothing to be nervous about! You have your backup and that's your insurance policy. No need to backup the IMEI. These are CDMA phones, not GSM, and the IMEI in the form of a HEX ESN is stored in a place that flashing ROMs does not overwrite it.

     

    Since you made the backup in ROM Manager, I would suggest installing the Sprint version of CTMod 3.8. You won't have any ghetto Boost branding or whatever weird system apps they have. It's the exact same hardware so the ROM should work fine. As Mike notes above, his Boost-branded Marquee had the Sprint ROM flashed to it and he said it worked fine. He also points out that TIng uses straight Sprint settings, whereas Boost might use their own settings.

     

    Respond back when you get further into the process. The only thing you'll have to do after flashing CTMod is changing the MMSC URL to get your MMS picture messages working. To do that, follow these directions:

     

    1 - Open up the phone's keypad as though you are about to dial a number 

    2 - Enter # # 3282 # 

    3 - Select MMSC 

    4 - Select Edit 

    5 - Enter your MSL (call Ting and ask for this, they'll give it to you instantly)

    6 - Select Set URL 

    7 - Enter  http://mms.plspictures.com 

    8 - Select OK

    Then send an MMS to activate.

     

    In my lengthy post above this one, I outline the steps to make the Marquee emulate the Android 4.x design with a custom CTMod theme and two apps from the Play Store. Performance is as fast as it gets still, but it just looks more modern :)

  • Anyone know if this same process will work for other phones, for example The Samsung Epic 4G?  I'm guessing the ROM will be different but is the process up until then the same or does it need a completely different setup?  Thanks for any help.
