Custom Kernel For LG Optimus L3 E400 Allows Overclocking Up To 1 GHz

Posted by & filed under Optimus L3.

We haven’t seen much development in the LG Optimus L3 community. There was a CyanogenMod 9 ROM and that too an official one which worked well on some devices but caused display issues in some. The reason was that LG updated the display drivers in new handsets but the CM ROM was built using old display drivers and hence the issue, too bad LG! However, there is a new Kernel that I was informed about by a friend of mine and a member of our Facebook Group, Vidur David who posted a screenshot of the device running at 1 GHz on stock ROM (LG L3 originally comes with a processor that runs at 800 MHz). He also reported that the device runs pretty smooth after flashing this custom kernel which also has Swap support. This means that if you use the Swapit RAM expander app, you can increase your device’s RAM by creating a simple Swap file on your SD card.

Sounds interesting? Lets proceed with the flashing.

People using CyanogenMod 9 ROM, please flash this kernel. It has the same features and fixes the blurred screen issue!

[box_light]We are not responsible for anything damage you might incur with the following process, try it at your own risk. Vidur has test this kernel and his device works on new display drivers. He could not install the CM ROM but is happy with this kernel as of now. Before you flash this kernel, I recommend you to backup everything using our backup guide. A nandroid backup is much appreciated.[/box_light]

Steps to Flash the Custom Kernel

  1. Download the kernel zip file and place it into your device’s SD card.
  2. Boot your device into recovery mode. If you don’t have CWM recovery installed, read this.
  3. Make a nandroid backup in recovery mode. You will need a lot of space in your SD card for this. Please do not comment below saying that you bricked your device and don’t have a backup, you will not receive any reply in that case. Read our unbricking guide instead.
  4. After you have made a nandroid backup, go to “Install zip from SD card”>”Choose zip from SD card” and flash the kernel zip file you placed in your SD card in Step 1.
  5. Go back and select “Reboot system now”.
  6. Install No Frills CPU from Play Store and overclock your phone as seen in the screenshot above.

Do comment below with your feedback about this ROM. If you face issues with this, we will be happy to help you (don’t forget backups).

P.S We are not aware who built this kernel. If you are the developer of this kernel, please contact us.

Thanks, Vidur.

    Lalit I have heard that this 1GHz overclock kernel have Wifi conection bug on Stock ROM.WiFi doesn’t work.And Yes I have findout about this kernel a few weeks before you.

    • Lalit Indoria

      You can usually solve these bugs by wiping dalvik cache and/or going to /data/misc/dhcp and deleting all files in that folder.

      • Boris Blagojevic

        There are two more Overclocked kernel’s of 1.2GHz and 1.5GHz range.1.5GHz is too unstable so OS will crash and faliure so you must that do completely fresh instalation of the operating system to fix that.With 1.5GHz overclocked kernel after first reboot it happends permanent system bootloop and you can’t reboot os so the only solution in that case Lalit is to manualy you know how to manualy turn into the ClockWorkMod ROM Manager and do the completely from the begining full fresh instalation of any Android OS like Stock or Custom ROM like Cyanogen Mod or MIUI.But I will test also and the latest at the moment 1.2GHz overclocked kernel.

  • Boris Blagojevic

    Lalit you are also an developer I think.So you really should very seriousely check this link about Overclocking kernels based on playfullGod’s changes.On this kernels are based 1.2GHz and 1.5GHz kernels and for LG Optimus L3 E400.http://www.modaco.com/topic/356069-overclock-kernel-built-using-playfulgods-changes/
    Here is a content about overclocking kernels how is created:

  • Boris Blagojevic

    Lalit brother please delete this outdated 1GHz Overclocked kernel because I was found last night at 4:36am Serbian Time the latest fully updated and upgraded 1GHz kernel with Virtual RAM memory swap paging file one is for Cyanogen Mod and other exactely the same for the Stock ROM.Soon I will give to you alink with thouse great the latest updated and upgraded 1GHz stable kernels. ;)

    • Boris Blagojevic

      Thouse kernels is made January 2013.You will really love thouse kernels.And you will see and notice that now in Memory you have now two setings first is the familiar cleaning puring RAM and other new is the Swap RAM enabled.I was already tested and it is great I can’t wait that fully test with the latest Oficiall Original Cyanogen Mod 9 ICS Nightly ROM 2.10.2013.

      • Lalit Indoria
        • Boris Blagojevic

          Moded ROM’s are definitely bad and stupid idea.I was faced with one very seriousely horible problem I almost lost my android.I was installed one ROM and my external memory SD didn’t work and every even the latest oficial Cyanogen Mod and even stock ROM after installing I was geting message instalation aborted and thank God I was fix that somehow few times I was restarted recovery removing battery and so one and now my android is finally ascepted the latest Cyanogen Mod it is defenetely bad idea and very dangerous taking ROM’s moded ROM’s from XDA and Modaco. :(

          • Boris Blagojevic

            Now my Android is fine and operational.All systems functioning properly.And the PlafulGod’s are good only for Disco Party Effect’s.When I was installed my smartphone was blinking black and white constantly without stop.

  • Boris Blagojevic

    Brother Lalit here is the link where you can find the latest fully updated upgraded and completely fully stable 1GHz overclocked Kernel it is on the top of the XDA page 187
    http://forum.xda-developers.com/showthread.php?t=1610666&page=187
    Please check this I already using this kernel and it is great much better than original 1GHz overclocked kernel trust me and please test this you too please and tell me your apsolutelly honest opinion.

    • Boris Blagojevic

      Lalit I was belived that I was learned enough about Android and like my father says”Now I see how much acutally don’t know nothing”.

      • Boris Blagojevic

        Today I almost died out of the fear because of one Moded ROM bug.I feeling like I was done something very seroius and unforgivable but”I didn’t done anything like that”brother.

    • T-ne

      Im using this stock kernel but the problem is the WiFi connection didn’t work. it says error. I hope that there’s a stable one, Im done using CM9 and other custom rom like annobox everything works fine with me but im not satisfied because of other bugs. that’s why I restore it to original stock Rom. ive been searching for a stable stock kernel but nothing found.

    When i reboot my lg e400 into recovery then after choosing install zip from sd card i choose select zip from sd card and it doesn’t show anything except a backup file. but when i choose select zip from internal sd card then it show’s the zip file. when i choose zip file from here then it installs perfectly but i can’t use my WiFi. . Please someone help me. i need my WiFi .. i m using default preloaded gingerbread and my phone is rooted.

    • Lalit Indoria

      This kernel actually has WiFi bug. :/

  • hazm

    Any solution for this???

    • Lalit Indoria

      Flash the stock ROM back.

      • T-ne

        Sir, I cant restore my backup that ive created it says md5 mismatch Im having a wifi issue that’s i need to restore it back.

      • T-ne

        well done, now i can restore it to stock rom done fixing my backup i thought my phone is broken because i cant restore it back to normal, all I did is to delete the nandroid.md5 and make a new file and name it nandroid.md5 then reboot and restore.

    • T-ne

      @Boris Blagojevic. Sir im using stock kernel that you’ve post http://forum.xda-developers.com/showthread.php?t=1610666&page=187. it works fine with me but the problem is wifi connection doesn’t work, so I’m planning to switch O.C. kernel V4 that you’ve post earlier but i have a question is there any bugs like wifi connection and other is it good for gaming? im using stock rom because the reason is I really need chainfire 3d to support for gaming, As you said it only works on CM9, so im going back to cm9 again because of this O.C kernel V4.

      • Boris Blagojevic

        No problems with WiFi with kernel V4 how I could see but I was stop using it because this V4 kernel is a cople of weeks was treatning to burn or damage my CPU and GPU So I am back on good old 1GHz OC kernel with swap enabled.I got many kernel panics with V4 kernel and on the boot screen was cut on top of the screen with one line.So I do not recomened avy more V1,2,3 and 4 kernel stay away from it or else you will permanetly very seriousely damage your LG Optimus L3 E400 with “V”Overclocked kernel the only most stable overclock kernel is thisone up here 1GHz with Swap enabled.Few hardware butons are stop working and I have problem with hardware motherboard caused by V kernels wich are manifest by few constant reboot kernel panics stop functioning hardware butons and hardware motherboard wich can be noticed in CWM Recovery Mode ROM Manager with charger pluged in for reacharge battery when start to scrolling down on his own without your influence. :( :( :(
