First, try Kingroot from XDA thread, it should work to root any KitKat or Lollipop on L90.

In second place, if you want to SIM unlock your phone to use it with other carrier's SIM then it's a completely different subject. Bootloader unlocking is just to be able to change recovery (and system, consequently). To SIM unlock you must contact the original carrier and request it or buy an unlock somewhere (also possible online).

Google search for KingRoot. It's not hosted at XDA nor is there a thread.

Maybe you have a stuck volume button? There is no reason to an L90 always start in download mode after a factory reset otherwise AFAIK.

LG Flash Tool and the original firmware. Flash it back to stock and then re-root. If the device is detected, it should be able to flash it.

  1. Uninstall the current drivers
  2. Use the LG Mobile United drivers found in this thread (Page 43 I think).
  3. Install the drivers.
  4. With the phone powered off, hold the volume up and down keys simultaneously and connect via USB to the comp/laptop to enter Download Mode. (I believe Qualcomm will still show, but as long as it detects the device, you should be good to flash).
  5. Select the .kdz file from the Stock ROM to flash to the phone.
  6. Wait until it is done...phone will automatically reboot into the basic ROM.

I have a LG L90 and it doesn´t boot to android(I don´t come out from welcomescreen, google error comes). And I don´t get it in the downloadmode, only fastbootmode comes. It´s not rooted. What can I do?

Does it remain on the fastboot screen? If so you may be able to proceed through the rooting process in order to boot a ROM.

My phone is booting up to the welcome screen. After network configuration I get everytime this error: "Unfortunately, Google Text-to-speech engine has stopped". After that the screen show me "Just a sec" and again the network conifguration. My computer doesn´t recognize it in adb (maybe wrong driver, I don´t know). But in fastboot my computer recognize this smarthone.

I meant in fastboot. (On a side note, if it went to fastboot to begin with, your bootloader was/is unlocked.)

Also, can you get into any recovery? Booting into recovery is a different key combination than download mode.

Try the command: fastboot getvar oem unlock first. It should tell you for certain if it is unlocked.

    First of all, This is not my original work. All credits goes to :cowboy:quangnhut123:cowboy:, who modified this tool for us. I am just sharing this GUIDE for easy flashing KZD to L90
    I have tested this method myself and it is working perfectly for me, but it is also possible that it might not work for you for some reasons, so don't panic, just post your problem or whatever error you are facing (please attach screenshot if possible). I or other thread members will try to troubleshoot it. After resolving the problem I'll update this post, so that other members do not face such problem again.

    • PLEASE, USE THIS TUTORIAL AT YOUR OWN RISK, IF SOMETHING WENT WRONG (because of your stupidity) ME OR XDA WILL NOT RESPONSIBLE FOR YOUR LOSS.
    • Flashing KDZ removes Root and CWM, so you will need to root again.
    • Flashing KDZ does not wipe your data, but if you get bootloops you need to hard-reset it, so please backup data first.

    DEVICES FLASHED WITH THIS GUIDE AND TESTED OK: LG L90 (D410)

    1. Download KDZ file

    To download KZD for you Device GOTO http://lg-phone-firmware.com/index.php?firmware=1
    Enter IMEI no of your device.

    attachment.php


    Enter IMEI Number of your LG Device and press Download Button. It will generate a download link for kdz file.
    Be warned the KDZ that your going to use will be auto deleted (may be not) so make another copy

    2. Precautions:-

    • Please temporarily disable any Adblock add-on in your browser and I recommend to check your host file
      C:Windows\system32\drivers\etc\host
      Enable Show Hidden Files in Folder Option (Don't disable this option until kdz flashing process completes) and Delete the LG Mobile Tool folder (if exist) from
      C:\ProgramData\

    • Remove all other USB devices (external HDD, backup drives, other phones, etc.) and cables connected to PC to avoid issued due to voltage loss.

    • OFFLINE KDZ FLASHING DOES NOT LOOSE PHONE DATA, BUT YOU MUST BACKUP YOUR PHONE IN ANY CASE.
    3. Downloads:-

    Download zip file attached below.

    4. Install LG Drivers (internet required for this):

    Extract B2CAppSetup.zip anywhere on PC and Run B2CAppSetup.exe as administrator. Accept Agreement and a window will appear. Click on OK button (Bottom Right) on instructions. Now connect your LG Device to PC in LG Software mode. B2CAppSetup tool will detect it. Now Click on Install USB Drivers (2nd option on Top Left). It will automatically download and install drivers for your device. If Install USB Drivers options goes grey (Disable) after detecting phone, it means latest USB Drivers are already installed.

    After installing USB Drivers please REBOOT YOU PC

    Now Connect Phone in Software Upgrade Mode: Switch OFF the phone and Press VolumeUP button and insert USB cable into the phone, Now phone should show Firmware Upgrade Mode.

    Let windows load any drivers, wait until it finishes. TWO ENTRIES SHOULD APPEAR IN DEVICE MANAGER IF DRIVERS ARE PROPERLY INSTALLED

    attachment.php


    After installing device drivers unplug the phone from PC

    5. Starting The Installation Process:

    Extract LG Flash Tool 2014.zip to C:\ drove of PC.
    Open LG Flash Tool 2014 folder and run LGFlashTool2014.exe and administrator.

    LG Flash Tool 2014 windows will appear.

    1. Select "3GQCT" in Type of Flash.
    2. Select "EMERGENCY" for PhoneMode.
    3. Select your KDZ file in the Select KDZ File box.
    4. Press "Normal Flash" button. (as pic below)

    attachment.php


    IMPORTANT: Do not change the names of the KDZ files. (They should look like.... "D41010a_00.kdz" or other version in same style.)

    Now "Read Phone Information" box will open with blank information, Just press "Start"

    attachment.php



    Now "Select country and language" small box will open. Here select "Different Country" and "English" and press "OK"

    attachment.php


    The utility starts the official LG Mobile Support Tool

    attachment.php


    After a few seconds a screen will appear saying "The phone is disconnected from PC.". Do not click on any button.

    attachment.php


    Now again connect phone in Software Upgrade Mode: Switch OFF the phone and Press Volume UP button and insert USB cable into the phone, Now phone should show Firmware Upgrade Mode and click retry button.

    Now actual flashing will start, and if your KDZ file is good flashing will end without any issue.

    JUST RELAX!! SIT BACK WITH HANDS FOLDED BEHIND HEAD AND WATCH IT HAPPENING.

    When it finishes full flashing and phone will start rebooting.

    YOU CAN REMOVE CABLE AFTER 100%, AND FLASHING IS FINISHED!!! Close all programs.

    In case of Bootloops try this :-

    SubliemeSiem said:
    This might come in handy for some people too:

    I just this method many times to go back to stock, but the last time I tried this my device got into a bootloop. I actually fixed this by shutting down the phone, starting the phone with the power and volume down button pressed, releasing those buttons when the LG logo shows up and immediately pressing them again, then choose to perform a factory reset. After factory reset the phone booted like I expected it to. Might not work for everyone, but is definitely worth a try before you try to flash the KDZ again.

    Heving Problem.....
    Here are some troubleshooting steps :-
    • Check USB Derives installed properly for L90.

    • When you connect phone in software upgrade mode with PC, Make sure Device Manager Showing Phone is connected.

    • Disable any firewall or antivirus if active.

    • when flash tool prompts to reconnect the phone or saying device not found, just unplug phone==> pull battery out ==> insert it back==> Reconnect phone in software upgrade mode and retry flashing.

    • If still not working, then quit flash tool => Restart PC => This time first connect phone in software upgrade mode to PC=> then launch flash tool and try to flash .

    • Disconnecting and reconnecting phone for several times could also helpful.
