Stupid mistake Firmware update bootloop (Flashed twrp too early) - LG G5 Questions & Answers

Hi Guy's,
I think I may have made a really blooming stupid mistake. After re-flashing stock due to some funny errors in my rooted rom I attempted to enter the bootloader again and flash trwp without unlocking the bootloader. I had the same adb window open from my first root and cycled through the commands and simply pressed the wrong command
So I'm in the infamous yellow "lock the bootloader" problem wherein it simply boots me into the firmware update. I had tried to do my previous restore to stock with LGUP that was successful however it throws up an error now as I believe it doesn't like that I updated in the mean time from buggering my phone up. (see attached pic) I have also tried to use a kdz for the 10i found here from the forum to only have LGUP crash upon initiating usb connection at 3%.
I know of no way to go back at lock/unlock the bootloader and I do apologise for the inconvenience but any help or pointers would be greatly appreciated.
Thanks a million!

"LGUP crash upon initiating usb connection at 3%..."
Maybe replacing dll file solved crash problem of LGUP and he flashed the stock Rom.

[Q] How to get back to stock

So my phone was rooted until I got the 4.3 update( Silly me for updating). Once I got the update and Samsung Knox appeared on my phone It said I had to disable it, well after following this thread http://forum.xda-developers.com/showthread.php?t=2565758 it disabled Knox, but I have some sort of problem with updating the SuperSU binary?

I click continue then is asks if I want to use Normal or TWRP/CWM
I do not have a custom recovery, so I clicked normal. Then it pops up that it is installing
after 2-10 seconds it fails and asks me to reboot and try again
I spent 4 hours yesterday trying to get it work and searching the forums(and google) for answers. At this point I am completely stumped on what to do. Any ideas? Can I get back to completely stock somehow so I can try again? Or is there a way to update SuperSU?
I will be checking back this is not one of those posts where someone asks a questions and does not return

Give this a try while phone connected to PC, run "adb shell" command, you should see $ prompt, then run "/system/xbin/su", you see root's # prompt. Please verify this before we proceed further.
I ended up just flashing stock then doing it all over again and it worked. Sorry for the late reply and thank you

Cant access recovery/Opreating System

my ROM is faulty and im trying to switch to another rom
but my home button is not working so i cant access the recovery
and when im trying to plug the phone to the computer im getting UNKOWN DEVICE ERROR
and because the unkown device i cant use the KEIS software to install another ROM
and ideas what can i do to solve the problem ?
thanks in advnace!
Hopper8's 'Odin troubleshooting' thread stickied in General, pay particular attention to the suggestions around connectivity (I.E phone/PC not recognising each other). these still apply to you even though you're attempting to use Kies (why you'd do this & not simply flash a stock rom manually with Odin I don't know, but, anyway...).

KDZ/TOT Flashing Fails, Bricked due to bad 47A flash

Hello, I am trying to return to stock for Miitomo/Android Pay to work on my G3-VS985 from CM13 nightlies with the last LP radios and boostack of 35B
Essentially what happens on all flashing methods is it fails to install the mtp drivers, and fails to connect regardless of OS bitness and version (Win10x64 and Win7x32 tested) and does not change the COM number on the phone's screen,
on one of the flashes it deleted the bootloader flash partition, and i re-flashed it in TWRP3, alongside all the 47A partitions except system and recovery, blaming possibly dead partitions of previous flashes, in hope to fix the flash mode
and here i am, stuck on just 47A flash mode which doesnt seem to respond enough to flash a KDZ or TOT
in the flash mode's status box it states "VUSER B60"
How likely am i to get this back up and running? and if so, how would i go about this?
THIS HAS BEEN FIXED, BAD CABLE
Glad you solved your problem! In the future, please put questions in the Q&A section. I'll notify a mod to move it.
You can also edit the title of your thread in the Advanced edit view, and put "SOLVED" in the title.
Edit: Also, are you sure your HD2 is dead? Or just resting? (Sorry, Monty Python reference)

Try to repeat the procedure, sometimes it might happen that odin get stuk, restart odin and get back to the download screen on your phone, you should be able to try again. If it keeps happening it might be that is the wrong version for your phone, I would suggest searching the original firmware on SamMobile and use odin to install that back.
Hopefully this helps, I'm no expert, just run into similar problems recently
