Only solution for me was to flash using LG Emergency Recovery

The offical LG update tool saved my life, it restored it
Xperia Arc S [lt18i]
ROM: latest FXP CM10
Kernel: Fusion Kernel 5.1
-
SIO | Smartassv2 | 0.2 - 1.6 gh

Thank you!
Thank you so much! My phone works again after a week of trying a lot of things

I was upgrading my LG P705 to 4.1.2 usind KDZ V20B, but it failed & its now stuck in emergency mode. The main problem is my PC is not recognizing it. I uninstalled LG drivers & installed again, but then also, its not recognised by my PC. Please Help.

Yeah so I had the same issue and tried this method, but i am not sure I got the right LG update software. Where do i download it from?
Also, when im running this, despite me running the little server the LG update thingy still connects to the internet and downloads a kdz, which fails to be installed on the phone.
I am trying this on a vista computer, will try on XP to see if results change.

My problem solved
before flashing use should care about alternate program running instead of KDZ upgrade tool, also need P705 dll files
i also stucked in Emergency mode i check Device Manager\Modem disable it and put P705 dll files and work nice
i also tell that we want better stable program instead of LG KDZ upgrade tool

LG E615 | Cross Firmware Flashing/Downgrading | Error 1002 | 4% Update Fail FIX

This post may be helpful for:​
1. People that are trying to downgrade from firmware they flashed.
2. People who accidentally flashed wrong firmware and now they want to flash the correct one.
3. People who generally want to flash a firmware using the KDZ Updater, ​
AND
Cannot do the things above because the KDZ Update tool shows the "Error 1002" or the update tool stops at 4%.
P.S. I have tried that on Optimus L5 and L9 when I had same problem and it works. Some users also told me it works on L7 too.
Go to post 2 for the solution​
Hello guys.
As the title says, I have tried to test JB(e610 model) Firmware to my LGE 615 with KDZ Updater.
The funny part is that I tried Europe v20B, which is supported for e610 and it (SEEMED) to be installed correctly. It wasn't obviously, that's why I'm here..! I had the usual " no touch " issue. The touch works ONLY after the first KDZ install, and after Hard Factory Reset for only ONE boot(and with SIM inside - If it's not it doesnt work). With the first reboot, the touch stops working.
Hence, I decided to downgrade it again to the previous version. So, I downloaded the correct firmware from LG site.
The issue is that NO other version other than v20B(Europe) for LG e610 is installed (no matter how many Roms compatible with e615 i tried).
I tried recovery from The LG Mobile Support Tool auto-update,KDZ Updater and offline installing it (Unbrick). The first 2 options give me this specific error:
Smart : wParam = 100, lParam = 1002
Step : Upgrade Error error code = 1002
Click to expand...
Click to collapse
The latter, gives me error in Connection with the phone(which I think is a bug)
The wierd thing is that v20B Europe flashing works. It seems i cannot "downgrade" it to an other version.
I thought "maybe it's because I tried e610 firmware" so I downloaded and tried older e610 firmwares but still nothing works. ONLY v20B-e610.
Of course I tried everything with disabled the LGE Usb Modem driver and with usb-debugging on.
Any suggestions?
Thanks in advance,
Moul.
EDIT: I've searched every possible solution online(Currently I'm trying to figure if LG Flashtool can do anything. Found the LG_E615.dll, but currently it says it cannot find the libusb0.dll....
Can anyone help? Maybe a link/guide for Flashtool?
EDIT 2: Ok, now I'm totally frustrated(and SCARED)... Stayed up all night and found NO solution. Tried LGMDP too, but cannot find a workaround...I tried either in Emergency Download Mode or in JB with no solution.... Is there any device compatible with e615 that i can use from LGMDP's devices??? KDZ still gives me the "1002" Error(Except of V20 Firmware).........
Am I at the wrong forum btw?*
If anyone knows any solution or has any abso-freaking-lutely ideas what I can do(Because I mine have ended).... PLEASE HELP!! :crying:
Please help..!!!!

KDZ Updater - Error 1002
Finally fixed it!!!
I installed downgraded CrossModel Firmware, and now my E615 has a E615 Official Rom.
As I said on the first post, there was only one firmware that worked and got installed with the KDZ Updater tool.(The v20b-for E610 - Europe) , so I downloaded the firmware i wanted to install, and "tricked" the PC into, thinking that it installed the 20b.
I don't know if that issue happened only to me only, but IF someone has the same problem another time, it will maybe work for him too. Or maybe it will be possible solution to everyone flashing a wrong Firmware..!
The thing is , I noticed that the KDZ Updater everytime it wanted to install a KDZ, it extracted it as a .DZ file at the "LGMOBILEAX" folder located in C/ProgramData folder.(In Windows XP it's in C:\Documents and Settings\<your account name>\Application Data\)
To fix the "Lparam 1002 Error"(Stop on 4% of update tool or crash error in KDZ updater ) I did the following steps:
1. Installed correct drivers from LG mobile tool to be sure my phone was recognized.
2. Moved battery out(Optional, by I prefer it if it's possible).
3. Entered Emergency Download Mode(By pressing the Volume-Down button while connecting the phone with the PC).
4. Extracted the -working-E610/V20.kdz and the E615/ V10.kdz with the Rom Converter Tool made by jes0411 (Original Post HERE), and renamed the extracted E615v10.dz same as E610v20.dz.
5. I started the KDZ update, choosing the working V20, and when the e610v20.dz file was extracted, I replaced it immediately with the (now renamed as "e610v20.dz") E6150v10.dz.
EDIT: If you are too scared of replacing files during the procedure, just wait until the update stops and ask you to restart. You can replace then it then.
Wierd issue from LG, but it worked for me!
Cheers.

Hello Guys...
I can CONFIRM that the process explained by moulwxtos works!!!!:good:
Just to add that in my case the first time I made the process the device stayed at the LG logo,, tried a hard reset without results, so I choose another ICS working KDZ file and made a second flash.... A succesfuly second one!!.
Thank you moulwxtos... your help was so appreciated..

You upgraded via KDZ Updater? Or by the in-phone updater?
If you upgraded via KDZ, you follow the same steps as the second post. The .dz files that you will need to replace are in the c://appdata/lgmobileax folder (on Windows 7 and with "show hidden files and folders" option ON).
If you didn't update via the LG KDZ tool , you just have to find a working (one that can get installed) firmware from HERE. I think it's better to download a Jelly Bean(V20) one, since you wont have problem installing it propably.
Try, the things above, follow the steps on second post carefully and tell me what happened.
Cheers,
Moul.

i have updated through kdz and i do the same steps as i updated but it gives me errors ..i will try the way you mentioned in post two ...its too complicated when i read it i didnt understand anything but i will try and tell you if i need assistance ..thank you mate

I can confirm that it works on lg l5 e610.
I succesfully flashed from v20c to v10l.

Brilliant!!
This worked for me!!
I tot my Ph was almost Bricked.. was searching for a solution but did not get it anywhere...
Finally this fixed the issue..
Thanks Mate..
Thanks a million..

Thx a lot! Worked like a charm! :good:

Hey guys,
Please help me out. I have an E615 that I wrongly flashed with with an E610 ROM using the KDZ Updater. I'm trying to use your process to get it back to the stock ROM but i have a problem, whenever I try to copy the renamed E615 file after extraction I get the message that the file is still in use and cannot be replaced. How do i work around this? Please help, I'm pretty desperate here

Hey moulwxtos,
I managed to figure it out. The problem was with the version of KDZ updater I was using. For some reason I couldn't replace the renamed .dz file when using the original KDZ Updater because it kept giving me something about permission errors. When i changed to the KDZ Updater with offline fox (UpTestEX_mod2_marwin) it worked flawlessly. My phone's back to normal. Many thanks mate

We can fix the "Error 1002" or the update tool stops at 4%. of the KDZ Update tool (I did with LG E615)
This way:
1. Installed correct drivers from LG mobile tool to be sure my phone was recognized.
2. Moved battery out(Optional, by I prefer it if it's possible).
3. Entered Emergency Download Mode(By pressing the Volume-Down button while connecting the phone with the PC).
4. Download a firmware stock version V10x_00 compatibly with your Phone ( From lg-firmwares)
5. With LG Flash Tool 2004 do downgrade from V20 to version Base V10, you just have to choose the V10x_00.kdz
6. I started the KDZ update NORMALLY and just Wait.
maybe later you can install the version V20D

Odin is only for samsung. For LG, use KDZ updater. You must download rom too. (Links in my previously posts) Not so difficult.

Just unpack your kdz_updater package with winrar in a folder where you want to use it. I don't see anything about incompatibility with win8.

i succesfully unbricked my lg thanks to kind people who knew how to do it.

Go back to 100% STOCK from 4.4.2!!!

Since so many people have asked if they can go back to 4.2.2 from using my 4.4.2 update thread :
http://forum.xda-developers.com/showthread.php?t=2692505
YES YES YES you CAN go back to STOCK 100%, the day it came out of the box 4.2.2 if you try out the 4.4.2 update I shared.
This is the Official direct from LG update/return to stock you'll be doing.
Heres how:
Make sure your usb drivers are installed.
Make sure you backup EVERYTHING you want to keep as this will wipe your LG G Pad V500 completely.
Now
Make sure your G Pad is ON, and plugged into your PC and It is plugged in with LG Software mode **NOT connected in "charge tablet" or "Media sync (MTP)".
This will ONLY work in LG Software mode.
Download this:
http://www.androidfilehost.com/?fid=23329332407582419
Install it and right click on it and Run As Administrator, just to be safe.
Open it and once you get to the screen click OK at the bottom...
The next screen will say "Your device has the latest software available..."
Ignore this.
Click on OPTIONS in the top right...select "Upgrade Recovery" give a few seconds to load and it's going to do it's thing
--It's going to ask you for 2 things: 1st line "LG V500" or "LGV500" or "V500" I believe I used "LGV500" and the 2nd line goes your serial number to your LG G Pad, it's on your box, OR the sticker on the back at the bottom of your tablet or I am sure there is an app or another way to get that for you, I have my box.
Now just sit and let it do it's thing and it will flash and "update" your LG G Pad V500 back to 4.2.2 stock, with the stock 4.2.2 bootloader.
You can root, use the Loki exploit, add recovery or whatever your heart desires.
((NOW GO CHECK OUT THE 4.4.2 update I posted and see for yourself if the 4.4.2 update was worth the wait, since you now know you can indeed go back to stock 4.2.2 so easily))
****IF you are stuck in an LG logo bootloop, do the following:
--HOLD the power button for up to 30 seconds until your tablet is OFF completely.
Now press and hold the power & volume down button
As soon as the LG logo shows up, release the power button ONLY, keep holding Volume Down.
While holding Volume down press and hold the Power Button & Volume UP.
You should be now holding all 3 buttons.
The Factory Reset Screen should appear, now let go of the buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset and press power a 3rd time.
Voila.
You're back to stock 4.2.2 100% and YES you can use the Loki exploit again! As this does go back to the 4.2.2 bootloader
GO ROOT and do your thing.

I used this method when I originally downgraded from the leak. The problem here that I've been asking all over the place is where is the file stored that is downloaded? This method will become obsolete without it because this tool will just download the kk update when it's released. The tool downloads and flashes the 'latest' firmware.
I've looked everywhere on my computer looking for the 1.5gb file that this tool downloads (currently 4.2.2) and I just can't find it....

Yup the tool deletes it after. You have to copy it out before the tool competes flashing.

Ok. So right after the dl while it's flashing, navigate there & copy it? Think there is a way to then use the file later with the same tool even though it's not auto downloading it?

It's doing the same for me

As predicted, this doesn't work anymore since it's downloading and re flashing KitKat. Is there a work-arround to stop it from downloading and feed it the 4.2.2. flash file?
I want to revert back to 4.2.2 but the guides i've seen so far seem complicated. This one is simple but don't work anymore.

Yes, it is possible. I did it two days ago following an italian guide, through google translate. I would post the link but unfortunatelly I'm not allowed, having less than 10 posts.
But answer me this: why do you wanna go back to 4.2.2? The reason I'm asking is because, after I downgraded and tried various ROMs, I reverted back to KitKat in a matter of hours.

this is required so one can retain loki and custom recovery patched in the latest bootloader , so the ideal way would be to
1. get to 4.2.2
2. Root
3. TWRP recovery
4. Flash 4.4.2 official zip via recovery thus retaining recovery and the loki exploit

You can also use the loki exploit, obtain root and then flash a custom recovery AFTER upgrading to 4.4.2. I know this because I did it.

I also tried it running official 4.4.2 but it seems like since there is 4.4.2 officially available it just reflashes the same system.

LINK TO UPDATED PROCEDURE:
Since LG has put the 4.4.2 image on their servers, factory restore now gets you a version without the exploits required to flash a custom recovery. The procedure in post #1 no longer reverts to 4.2.2.
Fortunately, there is another thread that discusses a workaround to this. If you need to flash a 4.4.2 device back to 4.2.2 so you can flash a custom recovery (and in order to have access to third-party ROMs), please see this post:

I hope this helps.

After updating my g pad to 4.4.2 the front camera stopped working. Android can't recognize it anymore so I'am downgrading to 4.2.2

Can't root!
Hello everyone,
I just got the LG G Pad 8.3 couple weeks ago. I've never been able to own an Android device that I didn't flash a custom rom on. I am currently trying to root this tablet, however, cannot do it for the life of me!
I've tried several guides on XDA but always end up with it not working. First issue I'm dealing with is that I cannot boot into the stock recovery. My recovery doesn't have the option to load from ADB. So, that's out of the question.
Following the guide within this thread leads me to the fact that I cannot go into "Software Mode"!!!
Please help me!
The specs on this tablet are the following:
Model number: CK810 4G :cyclops:
Android Version: 4.4.2
Software Version: VK81022B
Kernel version: 3.4.0

I cant open b2capp - it's showing- check your internet connection. But I'm all the time on wifi, I hv no idea what's happend.

For those looking for 4.2.2 or flashing their own KDZ. this has worked for me also as suggested here:

The LG Flash Tool 2014 is a modified flash tool that simply works without connecting to the network or utilize LG's Mobile Support:
http://forum.xda-developers.com/showthread.php?t=2797190
1. Download LG Flash Tool 2014 and LG Drivers
2. Put the KDZ you desire.
3. Set "Select Type" to CDMA (I think it doesn't really matter)
3. Set Phone Mode to: EMERGENCY
4. Click CSE Flash for complete wipe or Normal Mode. (I choose CSE but haven't tested Normal Mode)
5. Click the "START" Button on next screen.
6. Press "OK" (I've also choose English as language)

Autorec is damn slow and has no progress bar. While its gathering device infos it won't ever respond. Be patient and when Autorec finished gathering it will work. Good luck!

I get the pop ups that says finished gathering information and backup complete
still i waited 5 minutes ( lol... yess too long.. but just to make sure )
and press the screen... NOTHING!!!!
so i will think will flask stock
but KK
right ?
i already downloaded d801v20g00.kdz
and im now that one stock
BTW,
a friend of mine just got a NEXUS 5 and the camera sux
very grainy in marginal light, suppose to be very similar to the G2 but no!
G2 is way better camera
also i have read somehwere that you can install another camera package from the G3 or G4
if i an not mistaken and that is better than the stock G2 camera
The better the algorithms to render a JPG from the RAW DATA of the chip camera sensor
the best the pic looks
is XCAM the one ?
Well, im back to stock d801v20g
i am planning to install Cloudy v3 or CM13
any recomendation ?
i heard XCAM only work with stocks
so... tough decisions
