Problems after Downgrade - G3 Q&A, Help & Troubleshooting

Hi peeps
i seem to be having problems after downgrading from lollipop to kitkat 4.4.2 and used kHz file uk 10a
i did the whole kdz method n flash tool and although it worked and i am back to stock i can no longer edit APN details and also i can not update software in anyway.
iI have tried hard reset to see if this fixes the issues but no it doesn't, my computer no longer sees my device and also the same in LG suite, device not found blah blah.
I should also say with all this i wanted to also get rid of Mcafee but i can also not root my device now from what i can see, i can enter download mode but i also find it doesn't work
If anyone can give me some heads up ideas to solve this problem that would be fantastic

What's "kHz file uk 10a"? Kilohertz?
Don't use any shady .kdz files. If you search for lg g3 kdz files you end up on an XDA website where everyone shares his official .kdz link. Flash one of those .kdzs for your device and if you're using any v10x kdz you can root it.

Sorry i meant KDZ file it was the UK 16g D85510a KDZ file and i did indeed get it from here but not sure why I'm now having this problem
if i plug in my device it just shows as charging and is not seen in any other way

anyone ?

What's your version right now? KK or Lollipop?
If you're with KK what version is it?

hi thanks for asking
I'm now running kitkat 4.4.2 after the downgrade and the version I'm running is V10a-234-20

I suggest to root it with Stump root
- Download Stump Root app and copy it to your device: Click here
- Open File Manager app and install the Apk file. Do not forget to check Unknown sources option under Settings> Security on your device.
- Having installed the app, open Stump Root from app drawer and tap the Grind button. Stump Root will greet you with a melody while the device is being rooted.
- Wait till Stump Root works its magic and allow the device to reboot when you are prompted to do so.
- When you phone boots up, install SuperSU app by Chainfire (download it in playstore)
- To verify root access on your device, download a root checker app and run it.
- Then download TWRP: Click Here
- Flash it with Flashify (download it in playstore)
- Flash any ROM you want to make your G3 like a new one

I rooted my G2 using ioroot several times with no problems. Here was my basic method (based off memory)
- Turn on USB Debugging
- Connect G2 to PC in Charge Only mode
- Accept RSA Key (If you haven't already)
- Run ioroot.bat
- Follow on screen instructions (newest version is a bit different and requires you to change to MTP mode then back to Charge Only)
- Let phone reboot as normal
- Check root via Root Checker or Android Terminal Emulator.
Then you should be rooted and good to go.

What update are you talking about?
Thanks for your replies. :good:
i was able to finally achieve it. Here is what i did.
--first i flashed my phone with LG flashtool (TOT methods) using stock tot of ZVA version.
-- then upgraded the ZVA rom to ZVC
-- then rooted the phone using ioroot.
-- finally it was rooted.
I used a pervious version of ioroot before i posted this thread and that version created the faulty superuser directory which prevented the newer versions of ioroot to achieve the root.

this is what i think could happen if you use the old version of it once, and then using the correct version will not even root your phone.
In order to overcome this you need to reinstall your from stock so that the faulty superuser folder gets removed.
http://forum.xda-developers.com/showthread.php?t=2432476
i followed this forum to start from stock and then root the phone using ioroot25r version as mentioned earlier.
i followed the second method (the tot one).
good luck.

you can try installing custom recovery (TWRP or any custom recovery you want) and flash the Super user and remove kinguser this way should work i guess

sir please help me rooting my device ive got lg g3 d855 android version 5.0 software version V20n-234-30. thanks
Please help me root my G3 too. I'd love to know how
this is a simple way root your device not sure if it will work but it works with marshmallow tho
1)you will download kinguser apk from playstore and try to root your phone try to root your phone if it failed you will download the windows version of iroot from here http://www.iroot.com/ (you are rooted here)
If you want to swap to supersu
2)you will need to install a custom recovery which will be simple will install this from google play https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager&hl=en thats TWRP and will select your device
3)https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip you will need to download this zip and reboot to custom recovery you can do it manually or by this apk https://play.google.com/store/apps/details?id=fr.petrus.tools.reboot
flashing a zip: will be by pressing install in recovery then you will search for the zip in the location you put it in. im not responsible for anything happens to your device.

Either downgrade to Kitkat using TOT/KDZ and LG Upgrade Tool or if you want a one click method and trust Chinese downloads, then download Autorec and root package from:
http://pan.baidu.com/s/1o6YpUsE
Use password: rjte
Navigate to one of the folders which has kingroot app, which roots temporarily and then use autorecmm app for D858HK. This should downgrade bootloader to Kitkat, install TWRP, downgrade modem to compatible version and flash bumped MM boot image. Of course, permanent root with SuperSu will be there as well.
If you prefer DIY methods then there are a few other posts by me and @topet2k12001 which should be helpful.

Hi, you must install KingRoot latest version and Beta Super su 2.5.2. After this you would have enabled administrator permission.
In case of failure the update binaries in SuperSu, you must again install TWRP apps in order to install the custom recovery ( the latest version is 3.0) and finally, you must install the Supersu file (from recovery) in version 2.52 (is the one that works best on android Marhsmallow).

root is the problem, I am not able to root my Phone, I tried Kingroot, but no luck,
You must install to KingRoot in latest version from its official site. Then run the application and leaves that the process is complete. In the end, the application will show an error message indicating that it has not been possible to establish root on your phone. You should try to at least three times. If the error persists, install the application root check and verify if the root permissions have been granted.

I am not sure of the steps for your variant. You will try to do through of adb/console. Find on Internet how to obtain root permission from adb/console for your model.

Use lgup tool and install KitKat
lg up says unknown device
Okay you have similar problems As me 1.download and install lg mobile support tool 2.go in download mode -> to come there press volume up and power 3. Connect to PC 4. Make sure drivers are installed but the program will tell you 5. Let it install the latest update its official 6. Use LG UP again download mode etc same as before.. download kdz according to your phone 7. Select the kdz on lgup tool then lollipop should be installed or KitKat what you prefer and what kdz you installed with 10 in the name should be kit kat with 20 should be lollipop when I remember right. 8. Download kingroot from kingroot official website install from activate from unknown source if u don't have it ticked it will say its a threat go on the red text and choose install anyway. 9.Open kingroot root your phone with kingroot
10. Down and install autorec according to your running system either lollipop or kitkat this will install twrp or you can use flashify ( flashify is an app and to be found in the playstore) to get the newest version your decision well there u have it
Just do it with the adb(android device bridge) and powershell,...replace stock recovery with twrp .img file and its done
