You CANNOT install a custom ROM on this device without unlocking the bootloader first. I'm guessing that you have "LG Security Error" printed on your screen just below LG's icon? Never never wipe your phone without making backups first. KDZ and or fastboot are your only alternatives to repair your device at this time. There are several tutorials here to get you back up and running. Search is your friend

About a month ago I rooted my Samsung Galaxy Grand(the single sim version) with the help of Klingo Root, worked like a charm and had no problems at all. I even uninstalled all the bloatware samsung and the carrier had installed. About 3 weeks ago then an official update poped-up, so I updated my phone through Samsung Kies. Everything went fine, but after the reboot of the phone I noticed that all the bloatware was back, so I just figured, maybe i have to uninstall it again.
But then disaster struck SuperU said there is no SU Binary installed, so I though could have the update unrooted my phone? So I tried rooting it again with Klingo, doesn't work, I tried Framaroot, doesn't work either, I even tried to install Clockworkmod with Odin and it doesn't work. I even repeated the procedure while factory resetting my phone.
Has anyone else encountered this? It seems my phone is somewhere in between being unrooted and rooted? Everything else works fine.
Help! I just want to uninstall the carrier bloatware!

When you update your software it actually update your firmware. So the previous method will not work for this firmware.
1. you need to do it with different method if developers found it for you
2. just installed previous version of android .
3. May be fixed by factory reset..
4. You can even install prerooted custom rom like CM11
As per my experience new update will not that much compactible for all phones..
Hi, I'll start from the beginning, so I have a smart phone vodafone 2 (Alcatel V860) I wanted to upload the new software but accidentally I uploaded a backup of the tablet, after uploading the backup phone can not be connected as the flash mode, or in any way, you can not enter the recovery can not in any way connect the computer, the phone is as if dead. when I connect it to the computer when it is turned off the sound indicating that a new device has been detected, however, this software can not be installed. I hope that there will be a magician who already had a similar problem and knows what to do. Please help as soon as possible, if anyone knows what's going on I can talk about it on skype because it seems to me that it will be hard to even describe.
Thanks in advance.

No... Samsung kies doesnt provide feature to downgrade android.
You need to flash firmware package through odin.
you can google it for your device or search on xda...
All the best..

I connect my Galaxy Mega (i9205) to kies and it showed that my phone have new update. Bear in mind that my phone is rooted previously (CWM). Kies updated my phone to I9205XXUCNA3. I update my phone with no problem (it took longer time only) but unfortunately KNOX ruined everything. It keeps on saying that SuperUser is trying to access the system. Furthermore, my Wifi is not working at all. I tried to click on the toggle button but no to avail.
So after searching, I found out how to disable KNOX - By flashing using vcoreroot-v2. Done flashing with this file, and now I can't see my interna; SDCard. I'm doomed and now I don't know what to do to turn back to how it was before.
Anybody that can help me, really appreciate it.

I see that so far you have found a way to disable knox AND cripple your Mega...
IMHO the best way to fix this situation is:
1. Download once more your newest firmware I9205XXUCNA3 (e.g. from Sammobile) and flash it by Odin to resolve starting position. Or try to restore your firmware through Kies.
2. Then BEFORE YOU DO SOMETHING read forums to find information how safely root firmware with KNOX. You have to be known so probably your warranty is already void and if not so it will be on the first attempt to root your unit. You are warned... There are some threads about rooting KNOX-ed firmware and even how to come back (partially) to previous build.
BEWARE! Do not attempt to flash older firmware lest you brick your Mega. New bootloader prevent from downgrading and if you try you will have endless bootloop. Upgradindg to newest firmware is one way trip.
OK I've followed your advise:
1. Re-download I9205XXUCNA3 from Sammobile and flash using odin.
2. Re-apply vcoreroot-v2
and after reboot.... WALLA!! My phone is back to normal again! And same goes to my internal SDCard, back as normal.
I have a problem with messaging where it keeps on crashing at first. But then I boot into recovery, clear cache and apply factory reset.
Now, all back to normal.
Anyhow, thank you so much for the tips. Now I can ease out a bit

I am glad you are successful. Sometimes you have to repeat two times, but no more: one for download errors, two for your errors. But if then you are not successful... then you have to look for another solution...
Can I know what rom u are using before updating to stock rom using kies?
Sent from my GT-I9205 using XDA Free mobile app

Hi there, I hope somebody can help me after making fun of me.
I tried to root my devices. Everything went fine until I installed SuperSU via TWRP. Before I installed SuperSU I made a Backup using TWRP.
When I installed SuperSU my device seemingly was in a bootloop and stuck on the Vodafone screen; so I rebooted into TWRP and restored the backup I made before. After that my device showed the LG screen, then the "Your device software can't be checked for corruption." screen and now I'm stuck there. I can't even go into Factory Reset or TWRP, everytime the device is stuck in the "Your device software can't be checked for corruption." screen.
Is there anything I can do to help me with this nightmare?
try to go into Download mode and then install a stock kdz.
I'll try that now, will be back with news. Thanks for the help!

No problem. Let me know if you need some help.
On another note any ideas how to downgrade from 7.0 nougat easily?
Okay, it works again. Thank you for your help. I flashed Nougat directly, so at least there is something nice to it.
Hey XDA, I'm having a bit of a problem. I got my G5 just recently and I wanted to go ahead and unlock the bootloader so I could install some custom ROMS (I'm not a fan of LG's ux), but I ran into a sticky situation. I was trying to flash the TOT file for rooting h830 with LGUP when I found out that it doesn't work on Nougat. I tried to cancel it but now I'm just stuck in firmware update at 0%. The code at the bottom says 633A B50. I can get into fastboot but I can't really go anywhere from there and I've gotten to stock recovery but all it does is factory reset and boot me straight back to firmware update. I downloaded the stock nougat kdz file but LGUP won't flash it; sometimes it says invalid, other times it gives me the error code 0x2000 CEFS::Initialize. This is a brand new (kind of expensive) phone and I can't send it to LG for repairs since I unlocked the bootloader and probably voided warranty so I'm really desperate for a solution. Can anyone help me out?

Was your phone on the 20a version before you tried flashing the 10d root tot file and did you actually cancel the process within LGUP while it was flashing the phone?
Another user had a similar problem but he flashed the 20a version before he accidentally flashed the 10d root tot and he fixed it by just flashing the stock 20a within LGUP.
Assuming you can still get into download mode you should be able to fix your device.
Try flashing this kdz uploaded by @autoprime
downloads.codefi.re/autoprime/LG/LG_G5/H830/H83020a/H83020a_00_1107.kdz
If flashing is successful factory reset your phone from the stock recovery after.
Thanks, that worked but I had to do a little tinkering before it did. LGUP wouldn't flash it because it kept saying invalid and some other random reasons but I found a program called uppercut that allowed it to flash. I was able to get back to stock and then I used the dirtycow exploit to flash TWRP. All's good now on XenonHD.
so I thought I had a grasp on the unlocking rooting myself. I was getting the error in lgup where it doesn't recognize my device at all. I unlocked the oem and it did its own flash afterwards then I had to go and reset unknown sources. then I tried to do the lg up flash assuming all I needed from my 20i was the v10d arb01 may 23, I picked the upgrade and in the middle of it it failed. then it rolled back. so I tried it several more times in lgup and it failed so I tried the arb 01 march 4 with full root and it failed.
Edit: okay lI found uppercut and it reconnected me to LGUP then I used the flashable 20a file and that patched me right up. But no root, I can do a 1 click now I guess but what about a flashable twrp or can I just install it like the old cwm or x-parts? where to now? do I try the 10d one with root? I'm really tired of looking and blindly downloading tot and kdz files hoping they work? My main goal is to slap RR remix on this for anyone that would give me a hand
