LG VS840 Help!!

Got a bit of a problem.... I flashed a ROM onto my phone (forgot to back up, that's my big issue) It said it flashed just fine. Went to start up, just ran the lg logo for about 30 mins. Decided to try re-flashing it. Made sure to wipe everything. Nothing, still have the same issue. Tried to get back into CWM, but its gone now. Tried doing emergency download software, now its stuck on the screen "Download is in progress, do not disconnect cable." Im stuck. I dont know what else to do. I've tried the LG Support Tool, but it says to use Verizon Software Upgrade Assistant, which I can't get because I can't find a download for it and I cant get it from my phone.
I have the stock ROM image, but I have no clue how to install it without CWM or something. Any suggestions? Any help would be greatly appreciated! I needs my phone...

they said to use Upgrade Assistant that means you never told them about the truth: phone is not booting....big mistake or let me understand that:Upgrade Assistant works when your phone is in download mode ?!
what is that rom you tried to flash surely was for your phone ?
also you have stock rom this is a .zip file or what format?
can you enter fastboot mode ?

Um... Let's see... The LG Support Tool which in most cases you can use to return your phone to stock comes up with a message saying "Upgrade tool is preinstalled in your phone. Please allow to install "Verizon Wireless Software Upgrade Assistant" when the phone is being connected to the PC". That's what the tool tells me.
The ROM I tried to flash was BrokenOutConnect v1.0. Its for the LG Connect, which is almost the same phone, and some one said it would be ok to flash it.
The stock ROM is in an .img file, so I need to figure out how to install from that
And I have no idea how to enter fast boot (unless your referring to the vol up+down + pwr, in which case, that doesn't work.
Sorry, can't post the original page for the ROM, I'm too new lol

ok
I think was a bad idea to flash that rom because is not exactly made for your phone one can damage a phone in this way never do like that !
about your stock rom...maybe this is a backup made by stock recovery ? do you have a recovery.img file in that update ? there is a single img file in that stock rom or more files ?

No I do not... I actually just found that stock image on another forum. File is called LG_Lucid_VS840_4g_system.img . I realize that was a horrible idea... Google kinda led me astray on that one lol. I just wanna figure out how to return it to stock. Or if anyone has a link for "Verizon Wireless Software Upgrade Assistant", that would be much appreciated.

but do you have a backup of your current rom on your sdcard ? It's made by stock recovery if so search for a file named recovery.img
here is the link to your phone check if this is really your phone also download usb drivers and software to update it from LG site
install USB drivers then download and run LG Mobile Support Tool this will connect to LG site download files and finally will request to connect phone to PC then will make update

And do you think I need to do this if I'm just taking it in to a retail store? The store employee probably isn't going to check super in depth Will he?
What I'm asking is if I use supersu to unroot and then do a factory reset using the devices stock recovery would that he good enough to swap devices at the store?

Wasn't sure if it was stated still in my OP or not, but that error usually occured when flashing the tot method for the first time on a new phone, which you would use a button combo to factory reset while booting up the phone.

I tried a great many things to get rid of the 2 status and nothing worked... I think I reflashed no less than 20 times, and finally one took. The flash tool, if left alone would always come back as failed and I'd be left with a status 2. I tried factory resets, I tried various other little tricks listed here and there on the web (usb ports, plugging and unplugging at various times, etc) nothing worked... finally after a dozen or so tries at various trick methods, I thought, well let's just do it by the book one more time and see what happens, and sure enough I finally got a status 3 and a pass, pulled the battery and rebooted, everything is good now.

Also remember flashtool will almost ALWAYS fail.. Once its 85% its pretty much done. If it fails past 85% it's done flashing, the rest is just waiting for reboot.

yeah tried that too, it booted to a factory reset status 2 screen.
I'm sure I'm the odd man out in this process, but for me it wasn't as straight forward as all that. I think perhaps the answer for me was flashing multiple times until it finally decided to work. I know with the sgs3 (my last phone) some people had to flash multiple times and others didn't, I'm thinking it's the same here.

What matters is you have it working now

There just doesn't seem to be overwhelming evidence that returning to stock is completely dependable for the 850d. So I continue to pine for root.

changing from sprint firmware to att software

hi, i got my lg g3 at&t from my cousin upstate and i was trying to get some apps running on it and it most of them werent really functioning well because my playstore couldnt connect with google through mobile data and facebook app was doing the same so i decided to download the stock firmware for the phone. the phone used to start up as sprint so i download the sprint stock kitkat firmware and used lg flash tool to change it back to stock firmware. Then the network stopped working so decided to do background check and found that it was actually at&t version.
Long and short of it all is that i tried putting the stock at&t kitkat firmware on it using lg flash tool and always outputs download failed( mismatch device and firmware ). can anyone help with this.
i read on some forum that theres a universal dll that can with all versions for Lg G2 and was wondering if theres one for this one too
pls help i really need it to work

If that DLL does not work for you, You may need to use a HEX editor to edit the TOT file. But try that first

thanks, i already downloaded that and tried it and still fail and i cant wrap my head round the hex editing. Was thinking of installing twrp recovery and doing a full data wipe then after i use the lg flash tool to flash the .tot file on the phone but an having problems with installing the twrp recovery cos the firmware is sprint and the phone is at&t so i dont know which one would work. Thats even if its possible

According to this post you just need the flash tool and kdz but haven't tried it yet.

I just attempted it and ended up erroring at 9% with error 0x2000 CEFS:Initalize() :/ Attempting a redownload maybe I have some bad files.
*edit*
Was able to use uppercut by codefire(thread) to flash this kdz. posted in the other thread for this kdz also.

So what was your status before attempting? Did you do the unlock/root?

Sorry i typed that twice because i trashed my first post...
Thought i included it but apparently missed it the 2nd time
Im stock unrooted. So this was tested on a stock unrooted vs995. So ill be rooting in the near future. If someone doesnt test before me ill do it, but the uppercut allowed lgup to flash the vs995.

Thanks for testing that. If I knew it was 100 percent safe and wouldn't have issues, I would probably try the kdz with Uppercut to restore mine back to stock - currently unlocked, rooted, on 996 deodex.

Hey bro I decided to test this myself.. I was unlocked and rooted on vs995.. I just used the uppercut and LG up I did the upgrade option in lg up..
And it worked.. I didnt lose my data r apps but root is gone.. I will now see if I can root it again with Dirty Santa which I should Security patch is Nov 1..
Thats what i was on b4 when I rooted the first time.... Also if anyone can tell me how to pull the system.img and boot.img???? If i can get those

Thanks for keeping us updated. I'm probably going to stock restore too, currently on the unlocked deodex 996.
When you did the restore, did you wipe data before you started? I think I'm going to wipe and format storage since I'm on the vs996 Rom. Unless there's a way to wipe data in the stock recoverym

I didnt wipe data, i wasnt on deodex 996 rom. make sure u do the upgrade option in lgup

I tried to use Uppercut but it kept giving me an error that no devices were found. I have adb drivers installed and the LG mobile driver installed, nothing showed as error in device manager. Did you have any issues like that?
Edit: Weird, tried it again and it seems to work.

Thanks a million everyone, I finally fixed my Lg v20 vs995! I kept having failure trying it with Uppercut, but I finally saw that I needed to install 3 files to get it to work correctly, 1st you need the kdz file: VS99512A_06_1114_ARB00.kdz, next you need to install 2 driver files, LGUP_Store_Frame_Ver_1_14_3_3.msi and LGMobileDriver_WHQL_Ver_4.1.1.exe, and of course have UPPERCUT.exe. Finally after installing all of the correct drivers, and loading UPPERCUT, using the VS99512A_06_1114_ARB00.kdz, I finally got it to work and you have to choose "UPGRADE" in UPPERCUT, but I completely restored my phone to factory!!! What a frickn blessling, I am so happy, because I was trying for days to fix this..... and I actually threw this phone in the trash, hehehehehe, but something made be take it out of the trash an hour later, THANK GOD!

Has anyone downgraded from N to MM?????

Pretty straight forward. Seeing nothing but fails in LG UP even though the ARB passes. So it's not that.
Has anyone done it successfully? I've tried searching but no dice. (And i do mean via tot or KDZ. I'm aware that you can use TWRP to do it).

Intermediate steps
When LGUP has failed for me going back from N to MM - and i have done that many times successfully - it is because of an odd and, as far as i have seen, unidentified impasse unrelated to the ARB. Assuming you are on a later version of N (seemed to me to happen after about 20k), you should try an intermediate step before flashing MM. I believe flashing 20a worked thru LGUP and then from 20a i was able to return to MM with no failure. Hope that helps...

I would jump directly to tungkick's 10d pre-TWRPed tot file from 20a. Then upgrade from there to 10j or other MM.

Tried that too lol. Every single file I tried gave an error message. Not ARB, but something generic like 0x2000 - it wouldn't really say WHY it was failing. I don't have the phone right here to verify the exact error but there wasn't much to go on

Yes, i remember getting that error code before and eventually finding a way around it. What worked may have been as simple as re-downloading the TOT/kdz file (in case your file is corrupted) or switching to a different cable that could better handle data. Unfortunately, i just don't remember how i got around that error code. But i can say it is possible for a novice! I remember losing root and TWRP, returning to stock, and using easyrecowvery with verification disabled to reestablish root and TWRP. Sorry i haven't got my notes with me...

I think I tried every single version between 10d and 20a - they all failed. And the same cable worked to upgrade from 20a and then back down - tried it just for giggles. It was going down from 20a that I kept getting hung up on
