@ day ago I set off on a journey to root my phone so I could get xposed to work with pokemon go. I Followed a couple guides and every site stated that you need Twrp. The thing is im running marshmallow on the D850 and any time I try to boot my phone in recovery I get "boot verification failed" and get a black screen with the notification flashing and this even prevents me from even doing a factory reset. From lurking the forums i've learned that the best way to fix is to flash back to an older version of android but most of these guides seen old and out dated and I cant seem to find a kdz for the D850 . Thank you and your help will be very much appreciated.

If you dont find an mm kdz jut flash a lolipop kdz by using lg up....
The only way to go back to stock firmware on D850 is to flash a tot file using LG Flash tool (as no other method is currently available).
You can follow this guide for that purpose

Hey guys,
I really hope someone will be able to help me out.
I will try and provide as much information as possible.
I own an D855 bought from Germany. The phone originally came with the stock rom 4.4 I believe. I had rooted the phone using purple drake. few days ago I update the phone to 5.0 Lollipop, the official version rolled out by LG.
I lost the root after update and didn't re-root. Today during work my phone had gone into a boot loop (Logo->restart->logo-Restart). I though "okay that's fine , when I get home I'll look into the unbrick methods and fix this easily" Wrong.
I tried using the instructions provided by the user zedomax on youtu "How to Unroot/Unbrick LG G3!"
Downloaded all the drivers and the LG g3 Flash tool. Also downloaded a European stock rom. I got to around the 6:35 mark on the video, removed the cable and replugged it. Then the phone just shutdown and started a boot loop again. The boot loop had now changed to Logo->Firmware update page->restart->logo->firmware update page->restart.
Now I can't put the phone into firmware update mode anymore and I am really scared the phone is hard bricked. What is the next thing I can try?
I am offering a 60€ bounty to whoever has a fix for this.
I can also try taking a video of the boot loop if that would be of any help.
If I would try and RMA the phone, does anyone know would there be any sign of rooting. I had previously had the phone rooted on the official 4.4 build (using purple drake) and then I updated to 5.0, but didn't root.

please help me
Hello Everyone,
I have a VK700 and I totally screwed myself up lol.
So I originally had the device rooted, I dont remember how I did it, just that it was rooted a while ago.
So as some of you may know the Lollipop update came out and because I was rooted the update just kept failing at every try.
So after doing some reading I unrooted my device (not my best idea) and tried it again, only to have it fail again.
I was able to download the OTA update to the tablet and save the file to my pc in the hopes that I can somehow extract or make it flashable so that I could possibly root and then sideload or somehow flash it manually.
I have done numerous google searches only to find they don't actually show how to extract the files from the OTA update.
Any help is much appreciated, I would love to get this device running lollipop.
Also I have no clue on how to flash my recovery to TWRP or CWM and ideally I would like to so that I can make this process a lot simpler.
update
So I successfully re-rooted the device with LG One Click Root found on these forums (yay me)
Okay, a brief history.
I have an h818p, bought here in the Philippines. I wanted MM and it was taking a while to roll out here so I used the LGUP method and flashed a Russian 20c kdz into my phone. It ran okay but had some trouble with data connections.
I finally had some time to see if I can fix it so I decided to run the 20D euro into the phone and got some error so I ended up doing a factory reset. My data works perfectly now and everything is up, the only problem I have is that every single time I boot my phone I get this error.
I tried looking as to its meaning and I think it has something to do with the wrong kernel being in my phone or something like that.
Now if anyone can please help me, find a solution. I originally wanted to flash a kdz from the Philippines but the only one I could find was 10l. Now that the errors been popping up I cant get my LGUP to read my phone properly (it wont even let me set a kdz, its asking me to find a .tot file)
Now Im wondering if I can use the LG Flash Tool to flash the 10l philippine version and if this will help. I dont want to experiment anymore only to brick my phone.
Hello,
I have followed the Canadian guide to rooting my LG G4 H81210N.
I was on MM when i opened my brand new LG G4, i successfully downgraded to 5.1 LP for my right carrier.
I have downloaded the rooted img file to flash via the LG ROOT kit, following the rooting guide.
When i reach go to flash my rooted img (4.2ish gb) it takes less than 5 minutes for it to return with the pound # sign to show its completed the flash. i type LEAVE, my phone reboots fine, and i open up a root checker and super su with no success of a root.
I have tried using my original carrier (wind) KDZ and rooted img file, with no successs.
I have tried using telus kdz and rooted img file with no success. (as all canadian variants are compatible as i've read.)
So i have no clue what i am doing wrong. the LG root kit i downloaded contains SUPERSU 2.46, should i download a newer version?
thanks again for your help.
Please somebody help me out !!! ill even let someone use TeamViewer to do it or watch from your end, i know im not doing anything wrong but i just cant figure out why its not working!!
when i go to flash the rooted img, it stays for about 3-4 minutes and gives me the # sign, i let it sit for another 20 min and then rebooted, still nothing. I even tried using an american rooted img file to brick my phone so i know atleast its flashing something, but i couldnt even get it bricked haha sounds stupid but i have been trying to root for 4 days today is the 5th day i am going crazy!!!!!!!!
Problem is likely in the rooted image you're installing ...

Suggest you check out [Canadian Guide] - Complete Source for the LG G4 H812. Linux VM/Root/Tools&Files at: https://forum.xda-developers.com/g4/general/canadian-guide-complete-source-lg-g4-t3212449 and use one of the rooted images available there. It sounds to me that the image you've been using either isn't rooted or has been rooted incorrectly.
I notice you have not posted on that site so it should be a good source of info for you.
Good luck, S.
I have a g3 d855.
I was running 30b rooted and decided to tweek the ui soft keys (big mistake).
I ended up bricking but managed to use LGFlashTool without any problems to go back to stock "LGD855AT-00-V10e-EUR-XX-JUL-08-2014-32G+0.tot"
Then I installed 30n and found out it can't be bloody rooted.
I thought it would be simple to revert back to stock. 8 hours later and I am still stuck.
I keep getting "model information check fail!"
Is there any other tool for flashing the stock files as I am loosing my freaking mind here.:silly:
Thanks
