Hello everyone,
My dad has a Lg Leon H340F, which I tried to update without success to Android Marshmallow I followed the post "How to update LG Leon H340N to Android M and Unlock the Bootloader"
The first time I flash it, the tool showed that it was completed successfully but the phone didn't turn on, it was in a bootlop,
I thought I had done something wrong, so I tried again,
the second time the phone showed "COM5" while was flashing, the tool again showed the process was successfully completed but the phone was still in a bootloop, it no longer allowed me to enter the download mode,
When I connected it to the computer by pressing the volume down button, the charging icon appeared, the LG Flash Tool program no longer recognized it.
When I turned it on normally and while it was in the bootloop I connected it to the computer, it emitted the sound that something had been connectedt, but the LG Flash Tool did not recognize it either.
I thought all was lost,
I decided to try it with the official tool LG Mobile Support Tool, It did not recognize it either,
Then I realized that there was an option called "recovery error update" in which I was asked for the IMEI number, I entered it, and later it began to download the firmware, and was successfully installed on the smartphone.
Now he's alive, with lollipop, but alive.
I do not know if it will work in other cases, but give it a chance.

Thank you for reply, but all these solutions are in download mode or recovery, but I can't access any of that the phone is just dead screen not showing anything, when I connect my phone to pc without battery windows is showing "usb device is not recognized" error and keeps it beeping just like I connect and disconnect my phone every second (I have usb drivers installed)
You need to follow this http://forum.xda-developers.com/showthread.php?t=2585161, mine had the same error and fixed in 10 min!
Hi, I was looking everywhere since yesterday but can't find a solution. I had cwm + twpr + lollipop cm12. I've decided to back to stock, so as allways: driver, b2cApp, kdz, v20h and v10a, usb, s/w mode, xml parser, shhtp, etc... Standard offline kdz method. But during flashing I stuck on 15% and get the info that my phone anad pc are not connected by usb cable, I tried changing usb ports at pc, reinstaling everything, but I have still the same error. If that woldn't be much enough I ****ed something up and I think I don't have any recovery right now
I can put my phone in s/w mode but I stuck on 15% with usb not connected error.
I can put my phone in fastboot mode but my pc does not recognize it, its just pluging in and out it from windows.
I can put my phone in stuck on LG logo 'mode'
Any help? How to unbrick it? How to flash stock or at least some custom recovery? Of course unlocked bootloader. Please help me :crying:
Key it ****ed up even more.
When kdz show me to connect my cable i clicked retry, plugen cable out and in, kdz found my device, and go to step 2. In half way I had again the same error, so again clicked retry, plug out, plug in. Again founded my device, when I had downloaded 100%, same situation. founded my device, log that tool is extracting kdz and nothing. Waiting about ~1,5h, nothing happend, so I diconected cable. In that moment kdz go to third step and I get windows force close for not repodnig app kdz. I said a loud **** and started again. Phone has not been found anymore by kdz. After a few tries, booted to fastboot, and connected to computer. It has been found as Google Fasbtoo USB, no way to update driver to fastboot. I disconected phone and decided to try again with s/w but nope. S/W not turning on anymore (with or without battery). Fastboot not turning on any more. Just LG logo, when I'm connecting device to PC it is sometging pluging in and out but nothing showing in device manager
Any ideas? Please!

Hey guys,
last night I woke up, fining my phone constantly rebooting, so I tried to soft-reset it (pressed Volume Down + Power for 10 seconds). After this it booted again, but it was unable to find my SIM card or connect to my WiFi, so I decided to restore a recovery image. Note that I never installed any unofficial ROMs to this device before, everything was working fine so far, so there was no need to do it. It was running on the latest Denim-Update, that was available for the phone.
Since I was unable to recover the phone using the Windows Device Recovery Tool or the Nokia Recovery Tools, I launched up WPInternals 1.2 It showed me the correct (e.g. expected) product number and version (RM-821, 059S0K1). I then downloaded the emergency files and ffu-image from here (lumiafirmware.com/ser/RM-821/guid/059S0K1) (warranty ended about 1 year ago anyway). After rebooting into flash mode, the device started showing a Bluescreen (where only "" gets displayed), right after the Vodafone branding logo.
Since then I am unable to even connect the phone to my PC, nor do anything about it. I tried to follow this tutorial (docs.google.com/document/d/1FdTtfRcR80qnSzjHX1kvTcjMRcoWh8j5hUxw8UM_prE/edit) in order to flash the image directly using thor2. I had to remove the QHSUSB_DLOAD driver from the device manager (note that it was hidden for some reasons). I expected the "Nokia Emergency Connectivity" driver to be installed, but instead only a "NOKIA BOOTMGR" get's displayed.
Everytime I try to connect thor2 to the device, it says "THOR2_ERROR_CONNECTION_NOT_FOUND". I suspect this is a driver issue on my PC.
Do you have any suggestions how I could continue restoring the phone? Or do you think it is lost after all? (which would be sad, because I loved this device. The first one that was as reliable as I expected from it)
Thanks in advance!
I am constantly receiving
Manually invoked flash mode?
Hi, did you try this: switch on pressing the volume-up key? This should display a flash and a cog wheel. In this mode, you can use either thor2 or ImageDesigner to flash the required ffu file.
Refer to https://sysdev.microsoft.com/en-us/Hardware/oem/docs/Phone_Bring-Up/Phone_Image_Designer.
For download search for Lumia_Flash_Tools.zip. It provides 32 and 64 bit versions.

Hi all, new in this forum because i need to ask for help, i ve already read a lot of threads here but i couldnt find a solution. In this moment i cant aford a new phone and this one do all i need, so im trying to save it.
The phone suddenly restarted and get stucked in the LG logo. If i restart it, it stays in LG logo. I ve already tryed to hard reset it, but the same, it stays in LG logo. I cant enter in Emergency mode. The only mode i can enter is Download mode. So ive tryed to flash it with the stock rom, that ive used a couple of weeks ago in this phone when i had a similar problem, but this time didnt worked, it get stuck in 4% in the 3rd step of Flash Tool 2014. Ive already tryed different cables and usb ports. ADB does not detect the device, neither the fastboot, but the LG Mobile Support Tool detect it.
So my question is what other options do i have in Download Mode, that is the only mode that i think i can use?
My phone is unrooted, and my laptop is windows 7 64bit.
Thanks!!
I unlocked developer options on my phone. I didn't download anything or change no settings. A few days later my phone was acting odd. The it kept restarting over and over then it would get stuck on the tmobile logo. Then when it fully powered up i get a warning saying my device has been corrupted it cannot be trusted and will not run properly

Then it turns off and hasn't done anything since. Hard reboot will not work. My computer is not even recognizing it. It does nothing.
