[Q] F460k OTA update error

LG G3 cat6 F460k model. hi guys. I just received a brand new F460k and i am not able to update it to lollipop. When i go into update center and then phone version update, after clicking on check now for update, it gives me an error "update service is limited. Please contact lg service center". I am currently downloading the lg pc suite. I have attached the software information. Also, I put up in India and I don't know whether that's the problem as my G3 is Korean variant.
Also lg pc suite, but it gives this error "cannot run upgrade. Check phone status and retry". Is something wrong with my device?

These are all LG Korean refurbished phones.. But they don't support it and not licensed to sell in korea. That's why e-commerce sites selling these phones with deep discount. But I wonder can I able to flash lollipop kdz file manually. If I do so will it affect SIM lock or SIM network read issue?
It's going to download mode when pressing volume up button while turning on and I downloaded lollipop kdz for f460k. Can I go-ahead and flash it. Or it will give boot up or hard brick. It isolleh . Thank you.

And by the way still automatic download not working same error when checking for new updates. Planning to go back to kitkat stock and install any custom lollipop rom available.. Olleh is having annoying bloatwares in korean language to get rid only i need to go custom rom.

Flashing Original Carrier Firmware on LG G3

I purchased a used Verizon LG G3 from someone online. It has Verizon all over the device; however, whenever I turned it on, US Cellular popped up on the screen. The guy told me all I had to do was call Verizon and they would activate the phone.
I contacted Verizon, and they said there was nothing they could do. I talked to a friend of mine and he said that it looked like they flashed the phone with a US Cellular firmware as the device is a VS985 but it is showing up as US990 on the firmware. I have tried flashing it back to a stock firmware of Verizon using the FlashLG Tool and stock *.tot file to which it fails and just says device model is different.
My question is, is there anything I can do to fix this or is this phone basically a paper weight?
I'm kind of new to this, so any help would be appreciated.
Thank you
Try flashing 24b using the KDZ method...

Will flashing Firmware for Indian H818N model on T-Mobile H811 cause any issue?

I got the T-Mobile LG G4 H811 Unlocked from eBay. I am having issues with my 4G sim. Data is working on it. But, Call and messages fail.
I am thinking of flashing Indian firmware to test. can it render it complete dead or reflashing T Mobile Firmware will make it work again?
I am not familiar with LG devices. Above all this is my first LG Flagship device.
Last I had an LG G3 S and it was unlocked Indian version.
Won't work man.Don't do experiment.

F400s recognized as D855.

Hello, I have a Korean F400s LG G3 i rooted it and installed a ROM and it was working fine for a year or so, i wanted to upgrade to Marshmallow but i mistakenly flashed a D855 Rom to my phone, the phone froze up and now it only enter the fast-boot mode and Download mode when connected to the flash tool, i tried downloading the stock ROM for the f400s but the flash-tool shows me that it is not the Korean version, somehow the ROM changed my phone to a D855, i wanted to know is there any way to get it back to the old version? force flashing the old stock ROM? and if i just flash the D855 ROM will there be any danger on my phone? Thanks!

Can I update from kitkat directly to marshmallow? Plz help

Hello, I recently bought this phone G3 model D855 and would like to install the latest stock marshmallow version. Right now I have 4.4.2, so I am wondering if it is safe to flash marshmallow direct or do I need to update it to lollipop first. Also if you can direct me to the files I need and the procedure. Thanks
Some info about my device
Android 4.4.2
Kernel version 3.4.0
Buils number KVT49L
Software version D85510n
It is rooted
Also I checked the imei number on several sites, and it is showing Sprint as carrier, model LG LS990 suffix ASPRTN how is that possible if its model is D855, which is also printed back inside the cover. Also my imei ends with 855, so which firmware should I install for Sprint LS990 or D855 model?

Click to expand...
Click to collapse
Download LG PC Suite,install it.
Connect your phone to your PC and it will automatically detect and ask you to install the firmware update.
