Hello, I have my phone quite a long time. First I had on it KitKat orginalnego which I mentioned at the C11 later I updated it to the CM12. I am not happy from the development of CM12 wanted me to have on your phone Lollipop original HTC. I tried to upload the TWRP backup Lollipop but I did not work WiFi. Is there any other way to get back to the software HTC?

[Q] Go back to stock from CM12

So I flashed an unofficial build of CM12, literally hours before the official version came out, and now I want to go back to LG's stock software KK 4.4.2. But I'm new to flashing so I just watched a youtube video on flashing CM12 and did it. Now I can find no way to go back. I did try to use the LGflashtool, but my DL failed. Also, I'm not sure what my build number is. I think it's LG D855 10l but I'm not too sure because when I got he phone it was in English and not from India as the 10l suggests. I also have TWRP installed. I did no backup's or recovery, but the original software should still be in the internal memory right?
So what do I do guys? Did I goof?

The original software is gone, its not saved anywhere on the phone.
You need to find your stock file and flash it with the lg flash tool, its the only way to get back to stock in your situation.
Sorry, but I won't be able to help beyond that.

Well, thanks for the tip
At this point, it seems like I'd be better off keeping CM12 for a little while, no? I don't have the time or hear to fix this right now

Downgrade M8 back to Lollipop to KitKat

I've searched the forum and havent found a specific answer to my question. I am currently running 5.0 with the viper rom and its pretty damn sweet. my problem is a lot of my apps and some of the xposed modules wont work on lollipop but are compatible with KitKat. so obviously i want to go back.
is there any way to go back to kitkat without having to plug my M8 into a computer?? i would basically like to do it remotely and on demand, you know flash OS back and forth like you can do with a rom. can somebody help me out with the process if it is at all possible.
You should be able to run a KK version of Viper (or other ROM) with Lollipop firmware, as least from what I've read from reports by others. While old firmware causes problems with current ROMs; the opposite has been found to be a a different matter: firmware has been found to usually be backwards compatible.
You can always make a TWRP backup of your current setup. Then try a KK ROM, and if you have issues, just restore back to LP.
If you do run into issues, then you probably do need to downgrade your firmware to KK (need s-off to downgrade firmware; and not sure if there is a computer-free way to flash back to KK firmware).

Need help on upgrading my rooted LG G3 on stock KitKat (T-Mobile)

If this is posted in the wrong area, I apologize.
I have a rooted LG G3 with TWRP running KitKat. No custom ROM (I rooted it primarily so that I could write to the SD card).
Lately my phone has running strangely lately. It becomes unresponsive for >10 seconds from time to time. Sometimes I press the power button and it won't wake up. So I want to reset my phone and upgrade to Lollipop and load a custom ROM (maybe Cyanogenmod or Cloudy custom ROM). I'm going to use TWRP and Titanium to back everything up on the phone first.
I haven't loaded custom ROMs since my HTC EVO 3D, so it's been a while. I had some (very) basic questions:
If I do a factory reset, will I lose root? I really want to get rid of the stupid non-responsive problem, but I don't want to lose root.
If I load a custom ROM, do I need a specific version of Android to do it? I don't want to load and incompatible ROM and brick my phone.
I've seen posts of people trying to go back to KitKat. Are there any issues with Lollipop that would make my phone issues worse?
Since I can't take OTA updates, how would I upgrade my Android if I have to? Will I lose root if I upgrade?
Thanks for any help you can give me!

Thanks for replying. I have a LG D851 (T-Mobile).
So far I've done a nandroid backup and used titanium backup for apps and data.
I downloaded CloudyG3 2.5. Does this contain the Android update, or do I have to update Android before loading Cloudy?

I just have to boot into recovery, wipe dalvik, system, data, and cache, install Cloudy, and I'm good, right?

I'm also interested in this answer. The only reason I haven't updated to (any ART) rom is because I'm unsure if I can just restore a Dalvik backup without issues. The only way I would attempt is with TWRP.
i tried doing by Flash tool and it gives error like 0000008
bring up the post!
Curious as well. I'd like to get root.
Windows user not sure how to do it on Mac/Linux
by MM to KK I assume you want to take the LG G3 D851 from android 6.x down to 4.x
here goes...
----
http://lgg3root.com/lg-g3-stock-factory-firmware/
http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
use the LG Flash tool plus the two files, follow instructions on that second link step by step.
LGD851_20140611_LGFLASHv160.dll
LGD851AT-01-V10c-310-260-JUN-20-2014+0.tot
That takes you back to the 4.x kitkat stock ROM, not rooted or anything.
----------------
To go north from there back towards Lollipop or MM you can at this point use
http://www.download3k.com/Install-LG-Mobile-Support-Tool.html
B2CAppSetup.exe
Install it, will put an icon on your desktop, plug in your phone, open the app.
It's pretty much automatic, it updates the ROM from KK to Lolli, then if you hit "OK" it will update from Lolli to MM
- I just got both of these steps to work in the last 24 hours.
I'm still trying to find a valid "Root" method that doesn't ask me to install a funky ROM.
I went from a KK stock-rooted(TWRP 3.0) rom to the MM 6.0 Rom, realized I didn't really want to set everything up again, restored my KK backup. Only problem was I had to reflash the modem. That was a couple of days ago and the modem was the only issue.
I'm unsure about flashing a new/clean KK rom over a MM rom though.

I think I missed a step, in KitKat this phone needs a special command thrown at it so the memory cards will be read/write.
On the play store SDFix: KitKat Writeable MicroSD
I think that might be what I was missing last weekend. My phone is currently on MM but I can't root it with any method other than Kingroot and Kingroot is Bad News.
Yes. It's possible!.

[Q] MM back to LP or KK?

Did I read correctly (sorry, can't find exact post) that there is or may be issues when going from MM and downgrading to stock LP or KK?
I have put several MM ROMs on my phone and have considering going back to stock (or possibly recovering my original TWRP backup).
