LG Tribute HD LS676 Boost & Virgin Mobile GSM Network SIM Unlock

If you own an LG Tribute 5, you must have got it rooted with ease.However, its successor LG Tribute HD is amongst the latest LG Sprint prepaid phones running on marshmallow which is unrootable till date.

So since its release, the only gsm unlock solution known to me was via hardware tool called Gcpro key which is a costly affair and makes no sense for a single device. Then I came to know about a remote unlocking paid solution. I was just about to give it a try when I got a free and easy method which works without rooting the phone. Thanks to vittger @ xda forums. He wrote the unlocking method for LG G5 which worked well for Tribute HD LS676.

There is a small app called hidden menu call which gives access to the LG hidden menu without root.Follow the step by step tutorial to unlock your Tribute HD for free without paying a penny. Afterward, you can use it on At&t, Tmobile metro pcs, cricket etc.

You can download its apk file from the below link –


To do the unlocking we need to access LG Hidden Menu. For this, we’ve to install the downloaded apk file.

If you’ve downloaded the Hidden Menu Call app, get ready to install it. Click on the downloaded apk file.

It’ll say “Install blocked”. We’ve to enable “app installation from unknown sources” in security settings.

  1. I have a question..Someone stole my sim card out of my LG Tribute 676 (virgin mobile) and i am super upset…Trying to find a way to track or ping that sim card on my own somehow…It does have service on it..There is no superuser options for Lg Tribute 676 with PC or any apk install…Cant flash the firmware without causing serious issues…Does anybody know what to say to customer service when trying to get a free replacement on a sim card…any help would be appreciatted…Thanks..

  2. Hey Admin im trying to unlock my sim to switch from sprint to T-mobile and noting im trying is working any suggestions ????

  3. Hello. Pls i am from nigeria and after unlocking my LG ls676 the 4G and 3G network doesn’t work. It only work in 2G network. Pls what can i do to use it with 4G or 3G network for browsing. Thanks

  4. oy!!! i figured it out after the unlock, while the phone is scanning for the sim card, quickly go into the apn settings and the option to add will be available. add the apn quickly before it reads the sim card . worked for me guys try it out!!!!

  5. Would somebody help please. I got this lg tributehd sim locked just shows invalid sim. No hidden menu i found so far opens IOT menu. Any assistance would be greatly appreciated.

  6. how would one use this menu/app to manually configure spring (tello) (after removing the system update system app)?

  7. Admin – You mean it won’t work for version zv5. There is no way out…
    Also what is the service code when I type ##3282#

  8. yup, firmware update gives me an extremely ….useless hidden menu and zero ability to unlock this b!^ch. Boost will not provide unlock code, unless one stays with them for 12 months…..( this whole contract free shite does not sound great now) SO, they have the codes, you own a phone you cannot simply take anywhere. I have spent hours searching and filtering through crap and UNWANTED downloader offers to find a true, free unlock code.
    nope. Nothing. Why are people not sharing this?

    • The free unlock for me also worked until zv4. It automatically took zv5 update. After Zv5 the hidden menu has limited options.The unlocking needs to be done by z3x or octopus box & these devices are quite costly. I unlocked mine from this eBay seller for $9 4cdmaru . He’s quite professional. He also disabled hands free activation pop-up.

  9. Hi i recently got a LGLS676 HD TRIBUTE ,,I am really wanting to get it so i can change it from Boost Mobile carrier to Straight Talk me and my wife have the same phone, but before i do this like you are saying will this phone if unlocked be able to go to Straight Talk we live out in country and Straight Talk is strong out here when Boost is not, so before i do something i have never done i have this ?? To ask also do i have to unlock the sim card that came with the phone’s plz send me all the info to my Email account at Skinnink6778@gmail.com i really thank you for taking your time to read my concerns….we had these gave to us by family the phones are paid for and legit im dignosed with acute lung cancer and we need are phones for family and emergency use we are very poor and never have had a phone that are this nice so please help us…Again Thank you….

  10. how to get the service code? is this the UNLOCK code that we are all trying for? if so, i guess we dont have a way out. my current firmware version is ZV7., probably the hiddenmenu apk doesnt work for this version.

  11. I am still having trouble on my LG from Boost mobile. Can anyone please help with directions when using the ##3282# setting.

  12. don´t try to downgrade NEVER, you will kill the phone even from zv7 to zv6, or zv7 to zv5, or zv4 to zv3
    the phone will be black FOREVER

  13. hi, i recently updated the android system in my LG LS676, and the sim card was blocked, i tried to do what you said in this post, but didn’t work. When i open the Hiddenmenucall 1.7, just show tree options:
    -LG Hidden Menu
    -Version : 1.7
    AATest doesn’t work and the LG Hidden Menu doesn’t show any options of the shown here. If you can help me i’ll be very thankfull

    • Go to phone dialer and type ##3282# that will open the correct menu on lg ls676 you will need your security code to edit anything though so be sure you have the 6 digit passcode. Good luck.

  14. this no longer works, only shows
    Device test
    ELT test
    Factory reset
    Log service
    WVDRM Keybox when touched it say not supported

    is there any other way?
    thanks for your help

  15. I got no access to add new apn. I tried to long press the old key “otasn” but it seems no way to add or to edit the existing setting. Would you help me, please?

  16. It worked and then phone updated. Which makes phone to be locked again.

    And now above app does not have those menu items to do unlock steps.

    Please let me know how to unlock this.

  17. What am I doing wrong? Got the app installed but when I open it I do not see the options you are showing.
    Device test
    ELT test
    Factory reset
    Log service

    That’s s it. Please assist.
