Manually Update LG Optimus L5 E610 To Official Jelly Bean

Posted by & filed under Optimus L5.

So it looks like the LG Optimus L5 is one of the phones from the L-series that is receiving Jelly Bean love. Though this phone hasn’t seen too much development, other than a root and a working CWM for the ICS version. With this post, we’ll let you know how to update your LG Optimus L5 with official Android 4.1.2 Jelly Bean firmware. You can do this using LG’s software update program on PC but you can not be sure that you will receive this update on the PC. Also, even if you receive the update on the PC, you may not able to install it properly on your device.

LG Optimus L5 image6736 Manually Update LG Optimus L5 E610 To Official Jelly Bean

We recommend updating it using LG’s PC companion first and try this only if it doesn’t work. This update will also void root access on your phone (in case you already rooted it).  It’s not a big deal anyway because you can root it again and also flash CWM.

Requirements

  • You need the device drivers which can be downloaded from our drivers page.
  • Download V20a firmware (Jelly Bean).
  • Download KDZ Updater (Unzip the files and make sure you run msxml file while you install the KDZ updater).
  • Make sure you have backed up all data on your phone using our data backup guide because this process will wipe all data on your phone.

Steps to Update LG Optimus L5 to Jelly Bean

  1. Run KDZ udpater (KDZ_FW_UPD.exe) as admin.
  2. Select Type as 3GQCT and phone mode as Emergency as shown below:
    Root LG P350 LG Update Manually Update LG Optimus L5 E610 To Official Jelly Bean

    Ignore the .kdz file in screenshot

     

  3. Connect your phone to PC in download mode. To do this, press and hold Volume down button while connecting it to the USB that is connected to the PC already.
  4. Once your phone is in download mode, select the V20a KDZ file in the KDZ Updater.
  5. Click on “Launch Software button’.
  6. The Jelly Bean firmware will now be flashed to your phone.
  7. The initial boot takes too long usually. But if you seem to be stuck on the boot scree, you can perform a hard reset by removing and re-inserting the battery and then press and hold Volume down + Center button + Power button together. This will reset your phone.

If you face any issues with this, feel free to comment below. We”ll be posting a rooting and CMW guide soon.

    Mobile need to be Soff or not?

    • Lalit Indoria

      What does that mean?

      • http://www.tradecashforum.com/ Usman

        S off ?

        • Lalit Indoria

          It is only HTC phones that have the S-ON and S-OFF feature.

            Is there any difference in Korean android mobiles?

          • Lalit Indoria

            Again, I don’t understand. Difference is between two things. Difference between Korean mobiles and?

          • ravi seetaram

            they said the officail updat has been released how long will it take to reach trinidad

  • Marco

    Must the phone be off when you press and hold the volume down button. I am struggling with this part. Is there a more detailed guide on how to flash the update to my phone?

    • Lalit Indoria

      Yes, the phone must be turned off. I’m not sure how you are doing it.

  • Marco

    Well, as per your post, volume must be pressed before inserting the usb cable. I’ve done this more that once, and still cant get the phone to be seen by KDZ Updater. I have the latest LG drivers installed for my phone. PLEASE HELP

    • Lalit Indoria

      Try Volume Down + Center + Power button together. This may factory reset your phone but just in case if you wish to give it a try. I have seen people getting into Download mode via this procedure.

  • Moises

    to enter in download mode…turn off the phone…hold “Vol + and -” at same time…and then plug the cable in the pc

  • Marco

    THe update didn’t work using the KDZ file referred to in this post. Is there an update for South Africa??

  • http://twitter.com/SYFnMario SYFnMario

    I tried to get in the Download Mode with two different procedures. First, I tried with pushing and hold Vol – and Power buttons together and I only got a full screen of something written all over the screen and in the end “fastboot: processing commands” and I had to take out the battery to switch it off again.

    The second time I tried to push and hold Vol- and Vol + and Power buttons, but my phone does absolutelly nothing. Just the two soft-touch buttons blink once and that´s it.

    I don´t know what could be wrong. Maybe I should just wait for the official OTA update.

    • Joni

      Cool! works with me=)!

      SYFnMario all you need to do is holding volume + and – and while you hold you put the usb-cable to it. Tadaa and you have get to the download mode:)

      • twitter_SYFnMario

        Unfortunately, the result is the same in my case. All I get is this “fastboot: processing commands”. But no big deal. I don´t need Jelly Bean, ICS works perfectly so I don’t see a point to change it, unless it comes OTA. Then I will update it.

      • twitter_SYFnMario

        Joni, this time it worked! I finally got 4.1.2. on my phone. :) Here is what I have found out and it might help someone else also. So, when you press and hold Vol – and + at the same time you should first connect the USB part that goes in PC and then after that insert the micro USB in the phone. I don´t know why but that did the trick in my case to get in Download Mode. Thanks again! ;)

  • samar

    thanx dude its work great….keep it up

  • Srimoorthy

    Please someone tell whether the performance of the phone is increased by updating the Jelly bean.

    I wanted to try only if there is any performance improvements.

  • Mall John

    Good day.. i actually did it to my LG L5 E612 and it works fine.. For those who are using E612 and still having problems in entering download mode just press the Vol-, Vol+ and Power button at the same time and connect your original USB cord as fast as you can before the LG logo comes out then follow the next steps! God Bless! Thanks for this post!

    I have a lg l5 e610v (vodafone romania) and at me work only with a hard reset. I belive works only after flash make a hard reset by pressing volume down, home button and power booton together until backlight buttons are blink. After that release all buttons and you make a hard reset :). Thats works very well for me. LIKE HACKMYANDROID, IS the best site after xda developers. I wish a good day for all :D
