'Sup XDA,
I'm pretty new to this whole Flashing Thing going on.
My LG G5 is my first device where i flashed the Genysis Rom, TWRP and Root on.
Now i want to sell it to get myself a OnePlus 3.
Is there any way to completly get my LG G5 back to its Factory Mode?
Without TWRP, With Stock Firmware (even with the Vodafone Branding) and without the Text "Can't check for Device Corruption" on Startup?
Thanks and Greetings from Germany

Firstly you have to flash the LG Stock Firmware with LGUp, you can find it Here
Next thing to do is locking the bootloader, mind that this "lock" will only remove the startup message and lock the bootloader, it won't recover the warranty, you can find the method Here under FAQ

I recently purchased a LG Optimus G and started installing programs on it. once it got late I plugged it in to my computer (to charge it) and out of habit, i restarted the phone. It got stuck on the LG logo and kept saying Security Error...thats it...no number or any other explanation. I did a hard reset and nothing happened. I NEED INDEPT INSTRUCTIONS ON HOW TO RETURN IT TO WORKING CONDITION. I spent all night reading other post and devs or other users gave vague answers like "oh download this..." with no link....or use this with dead links.....PLEASE HELP THIS LG NOOB. .
The security error is from uninstalling bloat without having bootloader unlocked. You will need to restore using a program called lgnpst with stock firmware. Found here http://forum.xda-developers.com/showthread.php?t=2219953&highlight=jellybean . Links for lgnpst can be found here in teenybin thread ( you may also use teenbin files in place of stock firmware if you want to install custom ROM, it will unlock bootloader and install twrp recovery) http://forum.xda-developers.com/showthread.php?t=2230994 . If you decide to install custom ROM it will need to be on SD card so it will be available in recovery.
Edit... Be certain you have AT&T LG E970 model before attempting this, if you have any other model you will need to use different files.
I'm really sorry if the means of doing this has been posted but I have looked and I cannot find it. I would assume that I am not the only person who would want to do this, so if someone can either point me in the way of a definitive guide or tell me it simply isn't possible then I'm grateful for your help.
Here's what I know:
I can easily flash my Three UK (H3G) LG G5 to the open EU version of Nougat via Uppercut/LGUP
I can easily flash it to the EE version of Nougat for the UK
I can easily flash it back to the H3G version of Marshmallow
In the first two cases I get an error on boot which is related to the cust folder being set to H3G specifically. The only way to get the device to boot without these errors is to flash back to the Three firmware. There is no nougat firmware from Three for the G5 yet because they are utterly rubbish.
My question is, *is there a way to flash the open EU ROM, wipe or convert the cust folder by unlocking the BL and rooting, un-root, flash the normal recovery back on and re-lock the boot loader and basically convert my G5 into an Open EU model with OTA updates and no evidence that I have ever tampered with the device at all?*
Or do I have to accept that in buying a Three branded device it will always be hobbled in some way?
I've always found it incredibly easy to flash Samsung devices with ODIN so this level of PITA-ery is all new to me!
Thanks in advance everyone, and sorry once again if a guide for this has been posted, but I genuinely cannot find a guide specifically detailing the solution to my request.
On a side note, if I flash the Open EU KDZ (confession, I have), will I still get OTA up dates - for example, to 20C - once they arrive, or does the cust folder error on boot signal some borkery that will disable OTA updates from working?
Thanks again everyone
Also apologies but this should probably be in Q&A. Genuine user error!
Just find a European Nougat kdz flash it thro lgup and hey presto ....nougat on the G5 I've been running v20x ever since it was available.
I already did that, but I get an error everytime I reboot because even though I've flashed the KDZ for the open EU ROM the cust folder is still set to Three UK I believe. Was your device network branded?

May be you have to flash boot logo. I have never checked flashing boot logo like I did with Nexus phones.

There is no Three splash screen on my device - it is just running the stock splash screen now. The only issue I have is that I get the errors on boot relating to the CUST folder.
I am on tmobile lg g5, twrp installed, unlocked bootloader, rooted, running fulmics. I am returning the phone since the gps issues are becoming worse, and it has even started dropping cell service almost hourly which requires me to reboot. Can I completely restore to stock via flashing in twrp? Trying to avoid having to drive somewhere and use LGUP on a windows PC as I don't own one. Will the bootloader automatically relock if I flash the stock rom without flashing SU along with it? Appreciate any help.

There are stock ROMs (H83020a and H83020c) available to flash from twrp. You will not lock your bootloader nor lose twrp; but in order to get root again(in case you want), you will need to flash su. It worked​ for me perfectly and I have no issues with anything on my phone. The only thing that does not work (check screenshot for details) is google pay because since the phone is rooted "it does not meet the google's security standards." Now if you want to return the phone to factory state I believe there are threads here for that. If you still want to keep the phone just flash the appropriate zip and enjoy removing tmobile bloatware if you wish.

Ok. If you're wanting to do 100% stock, download the complete zip for 20c from http://downloads.codefi.re/autoprime/LG/LG_G5/H830/H83020c/LG-H83020c-Flashable.COMPLETE-ARB01.zip there. Put it on your extsd card. Backup everything that is on your internal sd (phone memory) like pictures, videos, SMS, etc. Once you've done that, boot to TWRP. Once in TWRP wipe everything except externalsd card, I also recommend using the format option to format the internal sd. Once you've wiped and preferably formatted data go to install and install the 20c complete zip you put on your extsd card. After it's done installing just reboot. This will overwrite TWRP and you will NOT have root. Your bootloader will still be unlocked though, so you still need a PC to relock your bootloader. Also I don't think encryption will be re enabled unless you flash the kdz though. Anyways that's your best way to return to stock without using PC.

I don't remember very well; but I believe it's hard brick. When I was researching to root my phone y read that somewhere, maybe here. I'll try to find the info on my PC when I get home.
Update:
I found the link. The advice is in the FAQ. Not sure if that would happen in your case since you have a custom ROM. The danger is when downgrading from H83010D to H83010A.

Thanks bro. I totally believe it because past phones had exact issue.

Just for clarification, if you're on Android 7, you can not downgrade to Android 6 without first downgrading your bootloader as it won't flash correctly. Also just something to always keep in mind with LG phone's at least, is that LG uses a antirollback system. Never attempt to downgrade from a higher ARB # to a lower ARB #, if you're somehow successful it will lead to a hard brick. Every firmware that autoprime has posted states what antirollback number it is on, so always check that. On h830, every firmware since 10D has been ARB01, only 10A or earlier was ARB0. While lgup shouldn't allow you to flash (should error out), no reason to take that chance. Hopefully that helps clarify
Hi guys,
I bough a used LG G5 back a couple of days because i have a lot of love for the LG G series. I got the phone after i had a quick look over the phone when i was with the seller and i was very happy about the external look of the phone so i bought it.
I had read that there is an official update for the LG G5 to Oreo so it was a big surprise when i realized that the one i got was still on 6.0.1. What i did was come back to the house, connect to the wifi and try to do a FOTA upgrade. No luck. It said that the phone was already at its latest update available. What i did then was to do a manual upgrade with LG Bridge. All went good and the phone was updated to 7.0. After the first reboot, i got the message "Current version is not available for user....". I didn't bother at the time because i thought that after a factory reset all would be ok. Well that didn't happen . I did notice something strange. The software version i had was referring to "EU" but now it says V20r-OPT2-SI. Perhaps the previous owner had the phone rooted and perhaps that version that it had was not the official EU.
Now the OS is full off bloatware and there isn't an update to Oreo available.
I want to:
- Find the appropriate OS version that my phone should have
- Get rid of the message that appears during the boot
- Get rid (if possible) from the bloatware when the correct OS is loaded
I want to use an official ROM with no root because of company regulations where i work so, rooting might be an issue. If i do have to root, i then have to unroot it again before use.
Because i have been away from the scene for a long time, please excuse my lack of information.
Regards,
If you don't mind loosing VoLTE support for the operators your rom was made for, just delete the /cust/ folder and you'll get rid of both error message and most of the bloatware.

That is indeed a nice tip that i was not aware of but would it be possible to know if i am able to flash a rom carrier independent in order to be able to upgrade afterward to the Oreo? If so, how can i find out the version that i can flash without damaging the phone?
Thanx for the help so far.
You can flash whatever rom you want (of course an H850 one, never try to flash a H830 or H860 ROM on the H850!!!). If you want to upgrade to Oreo having an Open EU stock rom, follow these instructions: https://forum.xda-developers.com/lg-g5/development/stock-h850-30a-eu-rom-flashable-zips-t3850072
If you follow colsely the instructions and charge the phone before proceeding, there's virtually no risk of damage (avoid flashing form a desktop pc in a stormy night, of course).
I installed a custom room in my LG V30 and then I started to have problems with the camera and other things and now I want to reinstall the official ROM and it remains in firmware now waiting for a connection and when I use LG Bride and my cell phone turns off to update stop responding and stay in firmware update

You don't say WHICH V30 you have. That's important information you left off. If cross flashed to another variant, what was the last stock firmware you used before installing custom ROM?
You can either:
* restore the TWRP backup you made before flashing the LOS- based custom ROM.
You did make a backup, right?
or
* flash TWRP-flashable zip (ROM) made from stock firmware.
Made for V30 with TRWP custom recovery by our Devs; basically stock ROM but with DTS 3D and other stuff already enabled. We have them for several V30 variants -- which is why we need to know what you have.
or
* use Dev Patched LGUP to install LG stock KDZ for your V30 variant.
Your Bootloader will still be unlocked. You will then need to follow WTF Section 6 Instructions to re-install TWRP, reformat internal memory, root. Unless you have T-Mobile H932, which uses different method to install TWRP. Which is why we need to know what variant you have.
(Saying you have a "V30" is like saying you have a "Dell" computer. It tells us very little.)

LG Bridge isn't going to work for you on LOS-based custom ROMs. It's LG software looking for LG stock firmware to update.

Thank you very much to those who have answered me, and tried most of the forms and just brick the cell phone, finally I read on a page that served to let much of the battery run out and try again and I did it and miracle It worked, I hope this helps another person with a similar problem.
