To unlock bootloader on LG Android smartphones, there are several different methods.  The easiest method is the official bootloader unlock method supported officially by LG.  For all other LG smartphones, you will have to find an unofficial version floating somewhere on the interwebs. Before you can root or install custom ROMs, you will need to unlock the bootloader.

  6. to get into fastboot mode on the LG G6 H873 "canadian model" POWER OFF, HOLD VOLUME DOWN & PLUGIN USB, HOLD VOLUME DOWN, then the device is in fastboot mode, but there is no way to actually unlock the bootloader !? it makes no sense..

  7. i have an LG G6 Canadian model H873 ,so could that mean the Bootloader is already unlocked ? if so how do i check it, just continue to follow the Command scripts till it get into the Bootloader ?

  8. Max i have a question. I own a Samsung Galaxy S10 Plus on At&t, but my phone is also unlocked as well. I want to convert it into a Tmobile phone. How do i go about doing that ? Meaning when my phone boot up it wont show At&t, but Tmobile instead.

  9. anyone know the unnofficial method for doing this on an LG k30 from boost mobile?? i dont want to flash a custom rom i just want to use my sd card for more ram so i need root unlocked i figured out how to oem unlock and enable debugging fine but i think if i go any further than that the phone will brick becuase its unsupported

  10. when doing this method on my LG it goes to the bootloader but it disconnects so I cant even do anything about it PLEASE HELP

  11. Max.i have lg h870v ,using official h870 pie rom ,i want to unlock bootloader can i use someone,s 870 unlock.bin file?

  12. it sucks you cant do it on the lg v30 H931 model. i just got one for $45 dollars just to use as a mini computer and to watch free nba apps that ios does not allow . oh well works nice for now until they force software updates on me . I guess ill buy a v20 model later as that looks easier to root and unlock than the model i got.

  13. What do I do if it does not boot into fastboot mode when I type adb reboot bootloader? It just reboots normally I have an LG LGL44vl

  14. Dear friend I need to reboot in my little lg k4 model 2017, as the 4 gb I deal with them only with social networks and nothing else, only that in tube tutorials I failed, because they say it takes the Bootloader lg k4. , before becoming the root, for your knowledge I can do it also from pc, if it becomes easier, then I connect the phone. for downloading the app thanks in advance for your answer and help

  15. Max… Is there an unofficial method to unlock the bootloader of the LG Stylo 4 LM-Q710MS on MetroPCS?
    I'm going crazy looking for an unofficial method since LG does not support this model.
