Can you flash Lollipop 5.1.1 (for example from this link) to LG G Flex 2 with this method?

 

[Sevillesv]

Heads up for rooted

If your device is rooted select the BOARD DL option, if not your device will go to a blue screen with LG Factory Reset Status 2, well at least that what it happened to mine, had a mini heart attack. Thanks for the guide!

I followed the procedure to bring my ls996 to stock with the zv5.tot but it is bootlooping at the minios screen.

Edit: I managed to enter recovery, I performed a factory reset but the phone still bootloops at the minios screen (doesn't even load minios). Does anyone have any idea on what to do next?

I followed everything that post #43 said but it still doesn't load minios. It reboots, shows it is loading minios and stays there for a few minutes then reboots again and does the same thing until it discharges. A minios bootloop as it doesn't let me do anything.

It stays at this screen:

 

[TECHNOLLIC]

Is this for the G Flex or the G3??
And it looks like its only sprint version.

I have used the lgflashtool on different lg devices besides the Flex 2 and this has never happened before. So I don't know what is happening with this phone.

Zip files?

If your device is rooted select the BOARD DL option, if not your device will go to a blue screen with LG Factory Reset Status 2, well at least that what it happened to mine, had a mini heart attack. Thanks for the guide!

Will this work with a zip file?

AT&T ?

Have the H950. You show AT&t Lg g flex 2. Do you have the KDZ files please ??

 

[Hasan AJ]

HI i need lg g flex 2 f510s/k..... Firmware (kdz file)please.

 

[gomhtog]

This method does not work with kdz files. There are no model dll files for kdz, and this software only works with tot and a dll file. I tried the method that was on the storage account you provided, that was for kdz files, but that too does not work with my H955. I have the firmware file for my device, but no kdz method available works for my device.

I don't know why you would load a tutorial and say it is for kdz and tot files, but it is only for tot files... Not judging, just wondering.

Any idea on a viable method for flashing kdz files?

 

[MasterSe7en]

Thanks broski

 

[shubh2007]

You are correct. This only for TOT method. If you have KDZ file then you should use LG Flash Tools.

 

[gomhtog]

You are correct. This only for TOT method. If you have KDZ file then you should use LG Flash Tools.

LG Flash Tools do not work, unfortunately. I have tried it about a hundred times, with different configurations, with different methods that are available on here, and on two different computers, but it always stops at 9% and tells me that there is no connection to the server and to retry.

That is the problem, you should flash the KDZ without internet connection.
