somebody may have some advice ...
[G2 General] hyelton:
Can you explain more??

What's your model? Your using a usb 2.0 port correct? Usb 3.0 will not work

What's the reason your flashing back to stock?

What firmware are you trying to flash?

And if you were running MM 6.0 you must use LGUP
[G2 General] Ghostv33:
The phone wasn't starting up just giving black screen after lg sign so I read download mode can be brought back using srk tools and did came back but when I try to flash the stock firmware after the flash starts the phone again goes into the black screen and yes I am using usb 2.0
[G2 General] hyelton:
If you were stock and didn't change anything and it started showing the logo that sounds like a hardware issue not software.
[G2 General] Ghostv33:
The phone enters automatically to download mode when I connect eith charger :3 but disconnects(black screen qhusb bulk) from pc while flashing :3
[G2 General] hyelton:
Okay but was the phone stock before? Just because it powers on that can still mean it's a hardware issue. Which download mode cannot fix.

Since you see qhusb_bulk the only possible fix at all is to use SRK tool
[G2 General] Ghostv33:
Ok thanks for clarifying :)
[G2 General] Hiyaslalabs:
I'm currently downloading the BIN_LGD802AT-00-V10b-SEA-XX-SEP-04-2013-32G+0.exe. Is this the tot file i needed? Thanks mate..
[G2 General] Hiyaslalabs:
I installed paranoid ROM then my device became unrooted. Then i flash SU and rebooted. Secure booting error happened. I can enter download mode but whenever I try to flash thru LG tool KDZ method an error keeps happening. It doesn't continue flashing. Any idea?? Thanks..
[G2 General] hyelton:
And what is that error? There's tons of errors it could be.
[G2 General] Hiyaslalabs:
Its a connection error. Keeps saying to disconnect the cable and re plug it.
[G2 General] hyelton:
Was the phone running MM 6.0 before?

Your using a usb 2.0 port correct?

And have you tried using LGUP?
[G2 General] Hiyaslalabs:
I have tried it on both windows 10 PC and the driver seems to work but nothing happens. That error still persists. From Device manager, should i set to port 41 even in KDZ method?

---------- Post added at 12:25 AM ---------- Previous post was at 12:23 AM ----------

Yes it was a 2.0 port. Paranoid is MM. LGUP? Not yet. Where to find that 'common' folder? And do I need to remove the battery of it? It is kinda complicated.
[G2 General] hyelton:
If you were running MM you must use LGUP.

LGUP you put the phone in download mode and flash the kdz. There's nothing else to that.

If what you were running was a CM based rom your best bet is to download a tot and use the normal tot method.
[G2 General] Hiyaslalabs:
Okay but a LL KDZ wil do right? as there is no MM KDZ available. I will try it later. i hope LGUP recognize my device.

---------- Post added at 12:33 AM ---------- Previous post was at 12:29 AM ----------

Should I install the installv_ver then secondly the codefire.msi?
[G2 General] Hiyaslalabs:
'Install the file with the DLL name in them first and then LGUP_Install_Ver_1_14_3 Then copy the folder "common" to C:\Program Files (x86)\LG Electronics\LGUP\model (this should resolve unknown error)'. Where to copy that common folder?

---------- Post added at 03:33 AM ---------- Previous post was at 02:51 AM ----------

I tried installing the drivers on windows 7 but there seems to be a problem. There is still exclamation on the device manager on lge android mtp device. How to fix this? Im on download mode. I manually located the driver on lg driver folder lgx64bus.inf but still an error persists. Thanks.
[G2 General] Hiyaslalabs:
Still couldn't find why mtp driver not installing any idea?
[G2 General] Hiyaslalabs:
'Failed previous error' whenever I try to hit that yellow button on lg flash tool. Does MTP driver need to be installed? Coz driver is not always installed correctly on my PC whether on windows 7 or 10. Thanks mate..
[G2 General] hyelton:
If your phone is in download mode you don't need the MTP driver... That's normal.

But wait, we're you using MM 6.0 before though?? You never said I don't think If so that's why it says failed previous error as you need to only be using LGUP if MM
[G2 General] Hiyaslalabs:
Yes MM 6.0 CAF AOSP based. But where to find that common folder you saying on LGUP?
[G2 General] Hiyaslalabs:
Model device still unknown, I don't know why the model I see is cloudy though I already flash a MM ROM after that. Already copied that common folder but still the same issue. Will it ever work if I remove battery of my d802? Don't know what to do.
[G2 General] heff91:
What a roller coaster, big thanks for this, since it worked the first time I did it. Big ups for keeping this thread maintained for so long man.

Then......when updating to a new firmware it all went south. I've spent like 12 hours looking for solutions and have now hit a road block. I'll post my issues, fixes in case someone ends up going down the rabbit hole I did.

How It started: Was using TWRP 2.7.0 to try flash a rom after successfully getting 4.2.2. Realised I didn't have the bump file for TWRP 2.8.2 so I System rebooted from TWRP.

1st Issue: Never booted properly and went into a loop.

Fix: By using SRKTool and restoring files.

Result: Magically TWRP was updated to 2.8.6 (SRK?)

2nd Issue: After wipes and formats '/data was reduced to 0 (Mb), couldn't add any roms via SD. /SDCARD was empty.

Fix: Used Repair and change file function in TWRP and changed file type to F2FS.

Result: TWRP folder appears in /SDCARD so I load roms and gapps in there to install.

3rd Issue: Installed latest Cyanogenmod 13 with Gapps, got stuck in perpetual boot to TWRP.

Fix: Flashed CM 13 recovery.img

Result: Could now boot to Cyanogen load page.

4th Issue: Cannot get passed Cyanogen load page.

Attempt 1: Tried wiping cache,data etc then reinstalling, using various cyanogen builds (stable older versions), orionOS but no dice.

Attempt 2: Tried restoring to stock 4.2.2 again via D802.kdz (this didn't work the first time for me) and D802.tot (worked the first time), both crash after loading a certain %.

My guess is that I'm still missing folders/files (from my initial format) that is stopping Cyanogen/other roms from compiling docs when it first boots and this is also stopping the tot method from working.

So....any clues? I'm burnt out.
[G2 General] hyelton:
Since it's showing unknown your most likely going to need to old tot method and get that working. You can remove the battery on a G2 (without taking it apart anyway). Removing the battery wouldn't do anything.
[G2 General] Hiyaslalabs:
But it is not also working on old tot method. And you told me lgup is the only way. Do you think my device is bricked?
[G2 General] hyelton:
LGUP is the only way if your running official MM which your not. What error in flash tool tot method do you get?
[G2 General] Hiyaslalabs:
So that is possible even if I previosly installed is MM rom but my device reading on LGUP is cloudy G2 3.3? Weird anyway the error im getting on flash tool is the previous load error. It doesn't continue flashing.
[G2 General] hyelton:
Did you try using the generic dll file? And redownloading the tot file?
[G2 General] Hiyaslalabs:
Even if I set this up on com41 its not getting 'Ready' on flash tool.

---------- Post added at 03:08 PM ---------- Previous post was at 03:05 PM ----------

Yes the generic dll I tried that alread. I dloaded this BIN_LGD802AT-00-V10b-SEA-XX-SEP-04-2013-32G+0.exe. Do I need to try the other two files on storagecow?
[G2 General] hyelton:
But you said you where getting a different error?

If you get passed the previous load error and its on ready make sure you changed the correct com Port to com41 the phone freshly put into download mode, using usb 2.0, using the cable that came with the phone /lg oem cable (yes it can make a differences sometimes)

And clicking the yellow arrow correct?

And if above is correct make sure your unplugging and replug the phone if it's still stuck on ready
[G2 General] Hiyaslalabs:
But it is not passing the previous load error? Don't know what to do. Doesn't seem a cable problem but I will try at home my LG cable.

---------- Post added at 03:11 PM ---------- Previous post was at 03:10 PM ----------

Iv'e done it nothing seems to work. Unplug replug the device.

---------- Post added at 03:32 PM ---------- Previous post was at 03:11 PM ----------

It was finally working. Thanks you're the man! haha. Unbelievable!
[G2 General] hyelton:
Okay but first you have to fix the failed previous load.. Right now it's a tot / computer issue with failed previous load
[G2 General] hyelton:
I'm glad you got it working :)
[G2 General] heff91:
Any idea on my issue from previous page hyelton?
[G2 General] hyelton:
Sorry I missed your post, what do you mean by crashes when trying to flash tot or kdz? What's the error message?

Have you tried using LGUP?
[G2 General] heff91:
No worries.

The program stops working and crashes at 6% (LG Flashtool tot method, using USB 2.0, running as admin) currently running windows 7. With the KDZ method I can't quit remember if it stops working as well but can't get passed 40% ish.

I was having trouble finding a MM or LP KDZ for LGUP, is it alright if I just use JB KDZ?

UPDATE: Tried LGUP method with JB KDZ, same issue with TOT method, program stops working at 6%. :/
[G2 General] hyelton:
What error is given or does it just stop? If lg flash tool is crashing like force closing that sounds like a computer issue. Are you using the usb cable that came with the phone?
[G2 General] heff91:
No I'm not, it's a nokia cable lol.

But since it's worked once before for me I don't believe that would be the reason.

In the end Cyanogen is installed it just has issues booting (missing registries/files?), and I'm guessing whatever is stopping cyanogen from booting is also causing issues for LG Flash/UP from installing KDZ/TOT.
[G2 General] hyelton:
Why not flash a stock based rom in twrp? CM can cause big issues with flashing back to stock
[G2 General] heff91:
I didn't even think of that.....I'll give it a try. Where can I find a stock based ROM?

Noticed that 6% is the Step "LAF INFO 1 1330794567", not sure why it's bad enough to stop programs from working though.

Any idea what that is?
[G2 General] hyelton:
Just look in the dev section and flash something based on your model/debloated etc. Dont know a specific one theres several just not one with a name or CM.

Sorry no clue when it comes to the LAF partition stuff.
[G2 General] heff91:
Okay, so I've tried Cloudy G2 and even CM 10 (which didn't even install gave me an error 7 error).

Cloudy still boot loops.

Tried CM 13 with a bootstack cause might as well, same.

So....stumped....:/
[G2 General] hyelton:
Don't try CM at all. That's not stock. As well as cloudy. You need to flash a pure plain stock rom like the Lollipop one.
[G2 General] dumbrose:
Hello mate i need your help big time. i am not an android geek so bear with me.

i have LG D802 Rooted . I was doing something with it today which involved booting the phone in recovery.

so i did following things.

1- Downloaded Autorec

2- Installed TWRP recovery through Autorec

3- Installed Flashify

4- Rebooted to recovery

after this my phone turned off and completely died. it is not responding to any thing.

I want to know by flashing stock firmware should i be able to use my device again?

also if yes, what version of kdz file should i download? lgkdz.com is not working. I have LG d802 32gb(INDIA) which was running on 5.0.2

Thank you so much in advance
[G2 General] hyelton:
You will first need to be able to get into download mode to flash stock firmware I stopped lgkdz as it wasn't needed. There's loads of D802 firmwares in the OP. Just flash a D802 India firmware just make sure you use the correct storage side 16GB in file name for 16GB kdz files.

If you plug your phone up and you GET QHSUSB in device manager you'll first need to follow the unbrick guide to get download mode working.
[G2 General] bender_007:
It could also be that your phone is refurbished frankenphone with actually different parts inside(motherboard)

Check device manager while connecting the phone to pc. If indeed 9006 appears and a lot of messages pop up - seek for srk tool. If there is a 9008 then either follow one of the links in my sig (thx to the authors) or seek for unbrick lg g2 9008
[G2 General] heff91:
Can't seem to find a ZIP of a stock rom (if I do they are for other countries, which im guessing can do?), they are all KDZ or TOT, is there a way to turn KDZ into zips?
[G2 General] hyelton:
You have a D802 correct? The first thread in the Dev section - http://xdaforums.com/lg-g2/development-d802/rom-stock-30d-flashable-zip-t3070383

Stock flashable roms.

Granted these are not 100% stock, but they're stock as it gets when it comes to being rooted, etc. THEN proceed to use LGUP and flash a stock firmware.
[G2 General] heff91:
Saw this before but was unsure if using EU roms are okay (im in AU).

Cheers man, legend!

The stock was all I needed, realised I went wrong when I tried to flash from KK to CM13 :/ and did a bad backup.

[G2 General] wulsic:
For the people who can't download the KDZ for their phones, I think that LG has renewed their download links.

so replace the XXXXXXXXXXXXXX with ur imei

http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=XXXXXXXXXXXXXXX

Then search for <sw_url> and copy the filekey=xxxxxxxxxxxxxxxxxx/D80230d_00.kdz behind

http://tool.lime.gdms.lge.com/dn/downloader.dev?

So it would be like http://tool.lime.gdms.lge.com/dn/downloader.dev?filekey=xxxxxxxxxxxxxxxxxx/D80230d_00.kdz for example.

this worked for me to download the KDZ fast without having to wait from other mirros like 3 hours so I hope this could also help other people.
[G2 General] hyelton:
Thanks for that :). I think that structure has been like that for awhile now at least 6 months ( I think) that was the last time I used it.

What mirrors did you say where slow? My mirrors in the OP are hosted on my own server which has a 2Gbps link and no where near slow :). If you ever have a slow acting download always try a download manager which I also recommend using a download manager with LG hosted links as well. As for me LG hosted links are slow without a download manager.
[G2 General] wulsic:
Well [MENTION=2607037]hyelton[/MENTION], for me the storagecow links were like 3 hours but that's also because my internet sucks a.t.m. even more then it would normally do so the LG servers are faster for me and something like IDM isn't an option for me as it would interfere with other programs I use and I didn't really saw the new links how it changed so I thought that it would be good to post it like that as I am going away from the G2 :good:
[G2 General] primus123:
Ok, i am stuck.

I am currently on the Cloudy G2 2.2 ROM http://xdaforums.com/showthread.php?t=2783192

This is the only ROM that my phone will flash.

I have tried every ROM in the threads for the Verizon variant.

So i decided to revert back to stock

kdz method the program keeps saying that the phone is not connected. All drivers are installed, i have rebooted phone and PC with no luck

tot method the program just stops, i follow instruction, get everything added and in place, then when i click start, it runs the dialog boxes on screen then they disappear, and phone shows no progress, but program only shows the exit/stop button, i have tried different USB ports with no luck, same result, each time i left connected for a minimum of 30 minutes.

Extra: So this phone was a extra, i used on the TMO network a while back, and worked great, i had the tmo rom for the VZW G2

http://xdaforums.com/verizon-g2/development/rom-t-mobile-20g-rom-vs980-1-16-15-t3004979

after i finished using, i remember connecting to computer to pull files off, and it was stuck on LG logo, and thats all she wrote for this one.

Any help would be nice, not something i need, just wanted a backup device, but i remember reading somewhere that VZW may have sent an auto update that crashed it because they were removing the other cell radios, or something to that affect.

Thanks,
[G2 General] heff91:
So what exactly is it your trying to do? Go to stock to upgrade or just return to stock?

You have a custom recovery?
[G2 General] hyelton:
Your putting your phone into download mode correct?? And using a usb 2.0 port? And with the tot method you changed you changed the com port to com41 in device manager? And unplugged and replugged?

Also some have issues flashing back from cloudy. Your phone should accept stock rooted Roms without issue. Verizon cannot push updates to a phone running a custom rom.
[G2 General] sga999:
I am going to try to help someone who has an AT&T D800 phone, possibly bricked, or possibly hardware failure. I'm following the instructions for the TOT method. But I'm not sure about the ccorrect files to use in the first download step 1.1. On storagecow, under AT&T, there is a Kitkat TOT folder with a TOT file V20c and a dll 20130811 (those are just parts of the names). However, there are also 2 zip files that appear to be older (i.e. V10d, V10o), and a dll that appears to be newer, 20130904.

Can you tell me specifically which TOT file and which dll I should be using? Also, step 4 says to extract the TOT from the zip. But if I'm supposed to use the TOT and dll that's in the Kitkat TOT folder, there is no reason to do an extract, right? Thanks.
[G2 General] primus123:
Yes trying to go back to stock, or flash any ROM.

Yes i have done all the complete steps, changed the COM to 41, i have unplugged and replugged. Yes it is a USB 2.0 port, i have tried all 3 on my computer. I do not have another computer to try.

My work computer has the USB ports locked off.

I CAN NOT flash anything. The device will just sit, i have tried every baseband, and bootstack combination out there. i have even tried mixing them up but still have same results.

It is really weird. This is the fist device i have ever messed with that would not accept a stock ROM, i have used every ROM that is flashable with no luck.

I will be home later today and will post back specific actions that the program does if that helps.
[G2 General] hyelton:
There's not a specific tot to flash as long as you stick to your model. v10 is jelly bean. So yes you might as well flash the Kitkat tot. No you wouldn't extract the Kitkat tot as its already extracted. The dll files are the same. You'd use the one for the D800 which is under the AT&T folder

Just make sure your using a usb 2.0 port and the phone is in download mode.
[G2 General] hyelton:
Your also placing it into download mode correct as well? You changed the lge or androidnet com port? And after clicking the yellow button when it doesn't flash you've unplugged it and replugged it there? Also each time you try your freshly booting it into download mode?
[G2 General] sga999:
Okay, I'll use the Kitkat tot. But about the dll, there are different sized ones in the AT&T folder and the Kitkat tot folder, so that's why I wasn't sure. I mean, one dll is directly under AT&T, but one is under Kitkat Tot, which is under AT&T. The first one is newer, so I thought I should use it. Yet it made more sense to use the dll that was with the tot in the Kitkat folder, rather than picking something outside of that folder. I think you're saying either would be fine?
[G2 General] primus123:
Yes placing into download mode each time i disconnect and reconnect.

I changed the com port, i had unplugged with program running, and turned off, and back into download mode, and still nothing. i have unplugged and restarted program, tried with and without ADMIN rights. Using original cable that came with device. I will try a different cable later today.
[G2 General] hyelton:
Next step after a cable is to try another PC as something is not right somewhere
[G2 General] primus123:
Tried new cable, same outcome. Press yellow arrow, and it does the little check, the last box is bin check, then goes to picture below. Am I doing it too quickly?
[G2 General] hyelton:
Screen shot of the commucation ports in device manager?
[G2 General] primus123:

[G2 General] primus123:

So, stupid question, phone battery is at 51%, is there a default value the program (s) look for before flashing?
[G2 General] hyelton:
Strange. Only other suggestion is try another PC.

Sorry if I've asked but does LGUP detect it?
[G2 General] hyelton:
About the battery sort of, But it will tell you. It wont just flat out not detect the phone like its currently doing.
[G2 General] primus123:
I give up.

I tried my Surface PRO 3 followed instructions perfectly, and nothing. I have tried 3 different cables, on both computers, i have tried both methods with exact same results on both devices.

I even pulled all the TOT files and tried with each one of those. Thinking maybe i was using the wrong one. Exact same results for each one.

I promise in my earlier statement that Verizon had done some push to the device that locked me up.

It really seems like i have a bricked device, but can not get anything to flash.

Ill stick to my Samsungs, i have them down packed. lol. If there is anything that you could think of that i may be missing let me know.

But i appreciate all your help for this. i know its an older device, and usually this long of time passes and noone really helps out.
[G2 General] hyelton:
You cannot use a Surface Pro 3... That device only has USB 3.0 ports.

As I said before Verizon cannot "push" things especially if you were running a custom rom. It's not physically possible. Only that would be pushed is a PRL update which wouldn't have anything to do with the phone software.

If you had a bricked device you wouldn't get download mode and you wouldn't see the com port in device manager. You really need to try another PC besides the one you where using and I think the surface pro 3 is USB 3.0 only which will not work.
[G2 General] primus123:
Again, thanks, however i do not have any other computers to try.

My work computer is Admin locked, i cant even update freaking Java without creating a ticket for it. The USB port on my work computer are turned off too. I only have the one computer to try.

Thanks for your help.

I appreciate all your help.

Something i never seen listed, does either of these methods require an active internet connection?

If so, then that is the problem. I have Dial Up at home, yes you read that right, i cant afford fast internet at home. I download files to my phone and then transfer them.
[G2 General] hyelton:
No it does not require an internet connection. Ouch Im sorry :( Usually in most places Dial up internet can cost more than a basic DSL service. Im trying to think what else to try, its detected by your computer and your sure your first computer your using usb 2.0? And you do see download mode of firmware update on your phone screen? Did you try and reinstall up to date Verizon LG drivers?
[G2 General] primus123:
I am positive they are 2.0

I can try updating the drivers. i will try that later this evening and see if that changes anything.

I have 5 USB ports on my computer, tried them all.
