    I just bought an LG Volt, and I stupidly let it update itself. So, it was on LS740ZV4, and was fully activated (with all the Vigrin Mobile crapware downloaded). And, I obviously couldn't root it.

    I followed the guide on this forum to use LGFlashTool to downgrade to (stock) LS740ZV3, then I rooted and installed this ROM.

    I couldn't activate the phone! I had to leave it overnight in order to activate it. (Does it only let you activate once per day or something?)

    Anyway, now it's all set. Activated, rooted, and on LS740ZV4 (I had to ##SCRTN# and then ##UPDATE#). BUT! As my carrier, it says "LG". It didn't download any of Virgin Mobile's crapware, nor do I see the Virgin Mobile log during boot up (like I did when I used the "official" update). I seem to be able to call/SMS/MMS/LTE just fine, but for cosmetic reasons I want the carrier to say "Virgin Mobile", not "LG". How do I fix this?

    P.S. I updated by baseband to c8.

    They called me crazy when I asked for the same thing.
    But it makes me glad I am not the only person bugged about loosing the career logo.
    I on the other hand want boost.

    And the only thing that really has the logo is the notifications pull down handle.

    I had this same issue, did not find a fix aside from starting over.

    What do you mean "starting over"? I mean, the carrier logo did work, when I was on stock (unrooted) LS740ZV4 (after buying it and running the OTA upgrade).

    I did "start over". I downgraded to LS740ZV3, then upgraded to the rooted LS740ZV4 ROM. That's where I am now, on the rooted ROM with a carrier of "LG".

    I wonder if I can change it via: https://help.ting.com/entries/23062023-Change-Carrier-Text-Requires-Root (I haven't tried).

    Flashing V3 and then V4 again and reactivating

    I've done this 3 times now, 2/3 times it was fine, but one time the carrier didn't get loaded.

    That happens to me too and I have to dial ##72786#

    What if we have someone that has the files saved up? Maybe we can "reinstall" the carrier

    I've done this and still have no carrier identification.

    I've never had that problem, my problem was I had to reactivate.

    It's weird, but I'm not overly concerned about it. The phone works fine. Was thinking about reflashing again, maybe it will fix itself.

    After flashing the rooted ROM, I did ##72786#. The phone did re-activate, and I can call and sms/mms just fine, I just (cosmetically) want to change "LG" to "Virgin Mobile".

    It seems to me that when it goes to activate or update the PRL, it can't write to the place it needs to (for some reason). It reboots after the PRL gets upgraded, but I don't get the Virgin boot screen.

    Why do you think that? Are you getting some error?

    No, I'm not getting an error, but since the phone doesn't boot up with the Virgin Mobile logo or say "Virgin Mobile" as its carrier, I'm assuming something isn't being set somewhere correctly.

    The reason it's not set is because it's a non carrier rom. It still works and updates fine so far as anyone has been able to tell. Fyi- the VM boot animation is on the phone, all of them are actually. As for the carrier text, maybe in build.prop?

    The boot animations can be found at root/system/media there is one for Virgin, boost, sprint and the generic LG boot animation as well. Jrummy's ROM toolbox lite and pro have a boot animation app built in and the app can also be downloaded from the play store as well, just don't install the tablet boot animations. Gravitybox has an option to change the carrier name as well, Xposed framework is needed to run GB i believe... I just tested the boost boot animation to see if it works okay and it does but I like the universal feel to the non carrier ROM, Much lighter on my cpu and memory as well :)

    *edit: I checked my Gravitybox settings and you can change your carrier name under lockscreen settings in the app. Hope this helps :D

    I was able to pull the framework_res.apk and swap out the eri.xml with a Virgin Mobile one I found online, and copy the framework_res.apk back onto phone and it fixes the carrier name on lockscreen and on notification dropdown.

    Now since i have boost i been trying to edit the eri.xml to change it over to Boost Mobile but every time i copy it back to phone I get force closes. Haven't been able to find an actual Boost eri.xml to just copy in so i been trying to edit the Virgin Mobile one.

    I'm sure i'm missing something but just have to find time to figure it out.

    In mean time does anyone have any ideas about editing the eri.xml or does anyone have the framework_res.apk from stock zv3 or zv4? It would need to be from a phone that hasn't been restored or had the modified zv4 rom installed..

    I haven't had this work for the Lockscreen, just the notification text.

    Same here i changed the pull down text but i use locker master DIY and i can change the text that way for my lockscreen. Some of the lockscreens they have look nice but they are practical too, for showing system info without hogging too many resources.

    OK easy fix for the carrier label on lockscreen and notification drop down. Edit the following 2 lines in the buildprop. They are located in different areas so you'll have to look for them.

    ro.carrier=unknown

    ro.cdma.home.operator.alpha=Chameleon

    Just replace unknown and Chameleon with your carrier or whatever you want and reboot.

    ----------------

    To fix boot animation...

    Using root file explorer go into /system/media and rename bootanimation.zip to bootanimation.zip.bak

    Then rename the appropriate carrier boot animation to bootanimation.zip

    Same thing for shutdown animation

    -------------

    To fix boot sound

    Using root file explorer go into /system/media/audio/ui and rename poweron.ogg to poweron.ogg.bak

    Then rename the appropriate carrier boot sound to poweron.ogg

    Same thing for poweroff sound

    But what exactly do we put? I assume it needs to be a specific thing.
     
  23. kwknott

    Put your carrier.. Boost Mobile, Virgin Mobile, etc.
     
  24. bg4m3r

    But just like that, or is it abbreviated or something?

    However you want it displayed it doesn't matter. You can put anything in up to 16 characters. Doesn't even need to be your carrier, can be anything you want. These 2 fields are just text info fields so they don't effect anything.
