How can I downgrade from 4.4.2 to 4.2.2 HELP PLEASE!

Hi all,
I have D802 G2 that had stock rom and I've upgraded to the 4.4.2 KitKat with the following manual:
http://forum.xda-developers.com/showthread.php?t=2665985
This is a vodafone official rom which is suppose to be rooted.
How can I downgrade back to the original 4.2.2 stock rom?
I tried the LG R&D Recovery tool and loaded the 4.2.2 kdz file and turned my phone into download mode but it doesn't work.
It keeps on saying that my phone has the latest updates by LG, I wanna downgrade !!!
Anyone can help ???

Anyone help?

I'm interested in it too. You can try to follow this guide: http://forum.xda-developers.com/showthread.php?t=2432476
but i'm not sure if it is ok to downgrade (I think it's safe). I tried it but unfortunately I can't finish because of an error that is occurred and I didn't find any solution yet. So by now I still have 4.4.2.

I have same proble. any help?

Reset to Factory doesn't work as a method to roll back? Or does upgrading to Kitkat also upgrade the factory restore image?

The factory restore image gets updated to kitkat. You have to use the guide Revert To Stock here on XDA and follow the instructions listed. Just follow them to a t and you'll be good to go. It's awfully hard to mess up. Even if you're not used to using methods like that it's easy peasy

you aren't using the correct tool. Find the thread Revert to Stock here on the LG G2 forums and follow those instructions. You will be using the LG Flash tool. Not the R & D tool. That's a whole different animal that is used for updating software. Not downgrading. All that tool does is search the LG servers for software updates and starts the install for you if you cannot receive an OTA for some weird reason. I downgraded my AT&T d800 using the flash tool method and it takes about 10 mins and then you're back on 4.2.2
The link the other member posted is the correct method of downgrading.

Well, simply in the last passage, when I have to chose the language, I select "different language" but in the second menu there are no language. Can I start anyway?

That's the wrong tool. That's the LG support tool. You need to use the LG flashtool that is listed in the tutorial the other member posted a link to. You don't have to do anything with languages if you follow the instructions. The tool you're talking about is used for software updates. That doesn't let you downgrade.

I have a Bell G2 on 4.4.2 that I want to downgrade and install a custom recovery. Those instructions say to use the LG Flash tool but when I download it, I notice that the source says ATT/Sprint/Verizon only. What do I do?

That I can't answer. I'm not sure if the At&t and bell images are compatible. I can almost guarantee they aren't. What you CAN do is just google search Bell LG G2 stock tot. I'm sure there would be either an xda link or a dev that had a repository of factory images for various models of the g2.
The easiest thing for you would be to search for your specific device model number (I.e. d800 which is the AT&T g2) tot. That should get you to the image you'd need for the flash tool.

I have tried searching for the tot file but there doesn't seem to be one for the Canadian variants. I have the 4.2.2 KDZ file though, can I just use the regular back to stock methods and flash it over my 4.4.2?
Edit: From what I see, only ATT/Sprint/Verizon models use the .tot and .dll method.

If you look in that revert to stock thread there is a link for the kdz method in there. Follow that and you should be golden. I forgot your variant didn't use tot

If I remember correctly the kdz method doesn't use the flash tool. It uses another method entirely. So if you got an error while attempting to use flash tools with kdz that'd be why.

I was using the R&D took for that. I followed the instructions exactly but no luck.

Idk, world war three.
The member said his version uses kdz and not tot. If your model uses tot then use tot. I've found it vastly easier than kdz. Either way you go just make sure you follow the instructions exactly for whatever method you decide to use. Neither myself nor the devs whose method you decide to use is responsible if you somehow mess up your device. If you follow the directions to the letter you should be fine but if you're not comfortable doing this then please don't. XDA isn't tailored for noobs. It assumes you have at least general knowledge of android modifications. Not trying to come off harshly so please don't take it that way.

I upgraded to kitkat via OTA. But due to audio noise problem I am looking to revert back to jellybean.
my phone previously had D80210F-SEA-XX (32GB). I can't find the JB .kdz flash file for my phone. I have come across D80210F-SEA-XX for 16GB but i cnt find the one for 32GB. Can someone here direct me to the link?
LG's csmg website only gives download link for the kitkat firmware of my phone.

Root your phone using towel root and install autorec https://www.androidfilehost.com/?w=files&flid=13763 then you want to download and flash this custom recovery from http://blastagator.ddns.net/twrp.html . Next you will have to flash the modem for your device. Since I assume you are running KitKat download the 20y modem from here and install via twrp http://blastagator.ddns.net/modem.php

Problem with getting back to stock lollipop

Hi All,
I need a little help here.
I have rooted my Zenfone 5 and installed Euphoria OS. But now i want to get back to stock. I have downloaded the latest lollipop firmware from Asus Website and followed the tutorial from Windroidica (Its for kitkat actually).
Revert back to zenfone 5 stock
But when i tried to sideload my firmware file in "Apply update from ADB", it starts opening update package, verifying update package when the file sent it only 2%. And when it reaches 52%, it starts installing package and aborts. No error message is displayed and the phone boots.
Can someone please help me with this. I am in a very bad position now.

I bricked my S7 Edge, might need some help please

Hi guys,
So yesterday i was trying to install the One UI rom to my S7 Edge, but i messed up in the process. I think the problem started when i installed the latest version of TWRP (twrp-3.3.0-0 i think), and then i reinstalled a previous version of TWRP over this one (twrp-3.2.3-0).
Anyway, after doing this my phone went into full bootloop with the logo "SAMSUNG S7 EDGE ...." on the screen. No big deal i thought, i'll just flash a stock rom with odin, but everytime that i try, i keep getting the same error "sboot.bin -> FAIL!".
I already tried :
- Using differents versions of odin, especially the latest (3.13.1)
- Downloading differents roms (marshmallow, nougat, lollipop)
- Using a different usb port
- Restarting my pc multiple times
This is the SM-G935F btw.
Thanks

Just flash the latest firmware via odin. Tell me you model number and I'll send you the link to what firmware you have to flash. Also tell me what firmware are you currently flashing which is giving error

Yup that is why you are getting the sboot.bin error. It means the bootloader on your phone is newer than the one you are trying to flash. That's why it fails. On you phone screen you would have a error binary 4 device 5. Something like this.
