Unbricking Problem

    Greetings.
    I have LG L4 (E440), and recently it got in Boot Loop (after I installed some programs it just turned off, and whenever i try to turn it on, it just shows LG Logo, then LG Animation and starts just repeating animation). At first I was quite confused because I didn't know how to enter download mode (you have to hold both + and -). I thought that was the only problem i was to encounter, but i was wrong.

    No matter what technique i use, regular LG Support Tool or LG Flashtool i always end up at Software Upgrade stage at 4% or 5%. In log it says that it is because of:
    drivers\mstrgen.sys file search fail

    Any help on how to fix this would be appreciated!

    What was the app(s) you installed? Google how to boot your phone into safe mode and if it boots, uninstall the app(s)
    (or if you've already tried a factory reset, don't bother)

    I had some errors with Viber, so i restarted phone and bootloop occured. I can't boot into Safe Mode, can't go into Recovery or Hard Reset (tried tons of combinations but none of them worked, each time i got in boot loop). I can only enter download mode. :saddroid:

    I'd try and find the firmware from a different source then if it won't download

    I downloaded 5 firmwares for LGE 440. V10B, V10C, V10D, V10E, V10F, all stock ones. From LG Software update tool I know that V10A is on phone. Each of these firmwares failed at 4% or 5% in Update phase. From log you see that error is drivers\mstrgen.sys file search fail. And in "Retry" window it says that there was connection error, even tho i have all drivers updated. I also tried front and rear USB Ports and tried both LG E440's cable and P970's. Same result. Also, i don't see any other ROM for LG E440 on net.

    Ahh sorry I thought you were having download issues .
    So are these firmwares for different models or just different builds for your model?
    EDIT sorry I misread..

    Sorry I have no experience with LG so can't help much :(

    Sorry then bro. Is the root forum for your device active?
    if not there's an LG expert on here but I can't remember how to spell his name to tag him lol. Hopefully he'll see this he's a good guy.
    Good luck

    Unfortunatly my device isn't rooted. :( I was planning to do it, but bootloop got ahead of me. Thank you for your help, it means a lot to me. Now if the iowabowtech could help me solve this problem, i would be the happiest person in the world!

    So are you flashing these firmwares as .tar files (unzipping them)
    I just know that's what you do on a Samsung

    Not really. I believe that for LG there are 2 methods for flashing. One is with .kdz and another one is with .tot files. I am trying to flash it with KDZ because it in my opinion easier and has less chance to fail, and i use it on my LG P970 regularly, so i know it better. The other method requires .tot files, but i doubt i will find any of them for LG E440.

    I've flashed my share of LG's but I have no experience with this particular model. OP, are you using the 2014 KDZ Flash Tool as seen here:
    http://forum.xda-developers.com/showthread.php?t=2432476

    If so, the only other thing that comes to mind is to be sure you have the LG United Drivers installed on your PC.

    Thank you for response. Yes, i am using Flashing Tool 2014. I'm gonna try again, uninstall all drivers, reinstall them and try again. I'll let you know what happened.

    Make sure there are no drivers from old phones on there :thumbsupdroid:

    I uninstalled all drivers. Both from Device Manager and from Add/Remove Programs panel. After i plugged phone in PC (phone is in download mode), this came up.
    [​IMG]
    As you see, i am missing some drivers.
    - CDC ACM Communication Interface
    - Unidentified Device

    I think that for Unidentified Device i need to download special driver for my phone, like LG E440 driver from LG site, but what to do with the other driver?

    Oh, and when i try right click on them and "Update Driver Software" it tells me that Windows coudln't find drivers.

    So, i ignored these fails. I downloaded LG Drivers from LG Flash Tool 2014. Installed them, and this is what i got:

    I managed to fix this... I had to use P970 cable and to use another USB port...
    [​IMG]
    However, the exactly same error comes up again. [​IMG]
    It stopps at 5% and says something like "Error has occured" giving me option to restart process. Unfortunatly i don't have log of this attempt, but it stopped at 5% so i guess same error prevented it to continue - and that is:
    drivers\mstrgen.sys file search fail
