This is true. However I have bricked my phone in the same way. I change the permissions and ownership of my /system/apps folder

when I rebooted I got and android man with a x in his belly.

I fixed it by doing this.

Follow the origonal post.

when flash tool checks your device state it will say that your device is not detected.

restart your phone with the usb cable plugged it and click restart check on your computer at the same time.

you device is detected for a split second when it is restated and flash tool will continue. it should say something like.

kernel version

battery state = 0

it should continue the process. then it might give you the same pop up as before saying that your device is not detected.

do the same procedure as before by restarting your device and it will continue.

then it will start to flash and tell you not to disconnect your device.

It will get stuck on 4%

dont worry just restart your device again and flash tool will send it into download mode. the rest is just a sucessfull flash.

if it doesnt send it into download mode just do it manualy.

I have sucessfully flashed my phone many time using this method.

hope I made sence. :-/

I guess what I am trying to say is that it will detect your device for a second if you restart your phone.

Hope this helped !

Thanks a ton Mircea89fzr and Slipsystem

I am a fairly new andriod User. Rooted my phone, the LG L5 II E450 using the chinese tool.

Worked fine. Installed an app to change fonts. Worked good after the first few changes, when I immediately rebooted.

On the last change, I selected "reboot later", and the next reboot ended in a bootloop.

Thanks a lot Mircea89fzr for the Tutorial :good:. I was hanging at the same problem as Ivan0550, but, the tip given my Slipsystem worked.:good: Thanks again.

I almost had a heart attack when the falshing completed and it appeared as if it was bootlooping again! :fingers-crossed:

Okay, got into some big trouble trying to flash this phone.

Picked up a firmware from my region (wanted Movistar Mexico instead of Telcel since I unlocked this phone) and it worked at first, but changed my IMEI so I don't have any signal and my SIM card is now invalid.

I have been trying some ways to change the IMEI (which I know it's a touchy subject) but I'd rather have my old IMEI back and get this back to normal. I can't even flash to the stock Telcel FW because the phone is unable to turn on after flashing, so maybe I messed up an internal driver of this. Anyone can help?

EDIT: Just fixed it with PuTTY.

[LG Optimus L3 II, L5 II, L7 II, L9 II] slipsystem:
I am willing to help you but you said if you pull vbs script over to command prompt it doesn't work which makes me nervous. the reason why it is not working is because the name contains spaces, try renaming the auto whatever its called to just auto.vbs then it should work unless you saved it in a location that contains spaces as well(eg. C:\users\Hello World\Flash\auto.vbs). I am not questioning your knowledge in computers but I am just think you need to read into the flashing process a bit more before even thinking of flashing your device.

I am also contemplating if I should help you because this bug in the flashing process is new but has been mentioned a few prior to yours. try reading back one page.

as XDA says if you don't take the time to find the solution which is almost always there for yourself why must someone take the time to find it for you.

if this didn't help send me a pm with a detailed description of your problem with some screen shots and I will gladly help you. if I am not able to help I will log into team viewer for you.

Thank you for your answer.
[LG Optimus L3 II, L5 II, L7 II, L9 II] slipsystem:
you need to remove this line from your hosts file

127.0.0.1 csmg.lgmobile.com

then run B2CAppSetup.exe wait for it to finish and see that your drivers are correctly installed.

Then continue from step 8

if you still have a problem you will need to uninstall from here

Windows 7

C:\ProgramData\LGMOBILEAX\B2C_Client

Windows xp

im not sure

you can probably delete the C:\ProgramData\LGMOBILEAX folder after uninstalling B2C client

but I have never tried this.

then

Download CCleaner from here

http://www.piriform.com/ccleaner/download/portable

Click on Run Clean

Then Click Registry, Scan For Isues then when its finished fix selected issues

Click yes

Click Save

Fix all selected issues

remove the line from the hosts file and start from step 1

are you sure you are installing the correct firmware this time?

If I had to guess, touch is a part of the kernel I think.

If you flash the wrong kdz you will flash the wrong kernel and touch wont work.

can you get root access?

maybe try flashing with the original flash tool not the offline flash

that worked for me when my phone was stuck in download mode

1. remove the line from the hosts file

2. open B2CAppSetup.exe

3. options

4. upgrade recovery

Doesn't work

If I do what you say the LG support tool says That the most recent version of software is already installed in my phone.

But I have two questions

1.- If the tutorial say that we have to include the line in the hosts file, why do you say that we have to remove it? Is it necesary or not?

2.- I never see the image that appears in step 21. And the program in step 22 is different that the one that I see.

Thank you for your help
[LG Optimus L3 II, L5 II, L7 II, L9 II] slipsystem:
the hosts file creates a loopback. I will try explain how this tutorial works.

ok so the first thing is installing the update utility

in order for the update utility to install it needs to get files from the internet. so that is why I asked you to remove the line in the host file. because if that line is in the host file it will loopback to your local network and not install.

then what we do is we tell it to install the kdz you have selected. that is why we put that line in the host file. because if we didn't re add this line it would try and download the kdz from the internet.

what the host does is redirects all programs on your computer to a different place for instance

will tell your computer to redirect csmg.lgmobile.com to the local host(wich is your computer)

saying that you can use it to redirect any website

will tell it to redirect facebook to redirect

then if you open your internet browser and go to facebook it will say page cannot be displayed.

Hello everyone :)!

I'm new here and I wanted to ask a few basic questions about this method. They are the following:

1. How were those firmware updates created (the .KDZ files in the link provided at the opening post) - if they were not legally distributed by LG?

2. What is the purpose of flashing your firmware with one of them - will you receive a newer Android system version (KitKat for example) or what?

3. Why those updates aren't offered officially by the LG PC Suite updater?

4. Will I lose my personal data stored in the phone if I install them?

5. Can I export an .KDZ file from my LG smartphone and how could I know what my firmware version is?

*My LG model is k455 (rooted using the VROOT method)

*Also note that I know x86, C++ and have been hacking PC games and examining Windows NT under-hood. But I've never been modifying mobile devices.
