Cannot Unroot/Stock! LG Suport Tool stuck at 4%. LG Flash Tool Stopped due an error

Hey Folks! I need help!
First sorry for my english, im from brazil.
I'm a Lawyer and i'm gonna sue LG company for a hardware problem ( SIM CARD REMOVED PROBLEM ). But my LG G3 have LG 6.0 Stock rom installed. I tried to root with King Root, it failed, but now even if i hard reset the phone it keeps installed!
(in brazil unlike USA, the company's don't support the costumer. They have given 1 year guarantee, i have the phone for 1 year and 1 month. They told can't help me but the brazilian Law says that if a unkown hardware problem appears then you have 90 days to sue the company.)
So i want to Go back to stock 4.4 ou 5.0, so if the judge need to avaliate, at least it will be known as unmodified.
When i updated to 6.0 Stock, i did with LG Flash tool 2014.
So i tried again to downgrade with LG Flash tool, but using the 20x kdz. I tried diferrent KDZ. My phone is D855P, tried D855 normal KDZ, tried 855P KDZ. but downgrade always failed " due to an error " on flash tool.
So i tried LG support Tool, gone do Download mode, but it stucks at 4%. ( and yes i tried to hard reset before starts the procedure.)
Someone can help me to unroot(i don't think is unrooted, but King root remain on the phone as a bloatware now), or return to 4.4 ou 5.0 stock?
thanks!:good:

I was thinking about. As i already use "stock rom 6.0" and i just figured out how to uninstall "king root app". So now my Phone looks clean from bloatware. Guess now i can sue the company without being afraid of someone detect some mod on the smartphone.

G4 Stuck in Encryption mode.

Hi I bought a refurbished LG G4 and I set it up and used it for one day and it was great. But I went into the about section and noticed that it wasn't running Android 6.0 yet so I connected it to LG bridge and updated it through the program. Next thing I know after it finished updating it booted into encryption mode asking for a password. I try enter something and it goes to 29 attempts out of 30 if I try it again it just stays there and doesn't change or or go below 29 it has now randomly changed into Chinese too.
I contacted the company I bought it off and explained it to them and said there should have been an explanation in my package. But there wasn't.
It's not allowing me to boot into recovery and I have no idea what to do.
I used this phone for one day and spent a lot of money on this phone and I have no idea what I can do to fix this situation.

not sure if flashing stock firmware will help... now the question is what version of android has right now.?
you can try the back to stock guide... not sure if it will erase everything .. but if you going to downgrade lets say you took the last update antiroll back 3 you can only downgrade to a firmware that its the same antiroll back version.. the last update from my variant its v3.. so ask first... then download firmware flash an d hope its wipes all and start from scrath..

It says on the website that it's running Android 5.1.
I tried the KDZ method last night and I would get and error when the upgrage was at 9%.
It's a refurbished phone, if that makes all the difference?

not sure, you best bet is to post that problem in that thread and provide all info and pic of error..

Use LGUP or LG FLASH TOOL 2014 for going back to the same kdz u were on? Also try to remember when u bought the phone did it had update center when u go into "about" u didnt try OTA via wifi?

LG G3 D852 downgrade from 6.0 to 5.0 Lollipop

I have been trying to root my LG G3 D852 on 6.0 mm, i have found that there is nothing out for that yet. I know know that have to downgrade and I have tried but since I'm on virgin mobile so the downgrade file I tried to use bricked my phone so i had to send it back to LG to get it fixed. Is there any other way to downgrade or root without bricking my phone again?
Thanks

Hmmm. I had the same problem as you did with my G3. Same model and everything. Tried to downgrade it using my computer. Can't remember what tool, but it said it completed successfully. When it went to reboot, it would stay on the LG logo for 15-30 seconds, before going to the broken android screen. After a few minutes, it would reboot. Could enter into the recovery menu from the broken android screen, but when I tried to bump the files or flash a rom, there was nowhere on the phone to store it. I think it removed the partitions during the flash, hence why it couldn't store the files. It's not that I didn't have permission, but it showed in the console that there was no directory to mount. Couldn't even charge the phone in the state it was in. Guess it relied on the OS to control the charging. I'll probably try to simulate the phone, with the stock OS, and see if I can find any exploits that could allow for a "safer" rooting method. Tell me if you find anything yourself!

Repairing damaged recovery partition on Huawei Y560-U02 - Solved

I watched a few videos on YouTube on how to upgrade the Android O/S but none of them mentioned that it needs to unlock the bootloader 1st.
So before I found out that I need to unlock it I tried installing ROM before I knew that.
The phone came with Android Kitkat 4.4.2 and there is an official Lollipop for it that I want to install.
The device is rooted with Kingroot.
I tried the installations two times and the phone still works but I can no longer boot into recovery mode or fastboot mode. It just hangs and then I need to remove the battery to get it to work again.
I just want to restore it back to what it was before and then I will work on unlocking the bootloader.
I prefer to use tools that are free of cost.

Issue has been resolved.
I flashed the device with a pac file using SPD upgrade tool and now all is back to default.

Hi. I recently messed up my phone (Y560-U02)! Please help me.
Can you please tell me where I can find the "pac file" and "SPD upgrade tool"?

You meant un-official, right?

Sorry for the delay. I check the linked email once per month.
Do you still need help on this?
I thought that it was official Lollipop. But it does not exist for this phone.
Yes I can help you get it to what ever you need but it is not easy if you want to do more than just resorted it back to default.
I will tell you more if you still need it.

Stuck in fastboot. Recovery available, no download mode, Octoplus instructions? I ordered one.

Hello, I unlocked my bootloader and then flashed the ulm kdz for this phone thinking I could flash roms on it. I went ahead and flashed twrp and tried to flash a few roms, none worked. Then I went and got orange fox recovery and same issue. No flash works. I guess I need to be on one of the other firmware? Problem is, I can't get into download mode. I've tried every thread on here to fix that.
Does anyone have the latest ulm firmware , the xml for qfil to flash or is it possible le to flash a rom over the latest ulm ? I can't get it to to boot, the most I've gotten was the spark os sign. Thanks in advance.
Or if anyone knows a remote service that would be good also.

What phone are you using, and what ROM do you want?

Disregard, I see you have a LG G7 ThinQ.
