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

Right Now at 2017.
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

[Q] [REQ] DLL for flashing D805 10B TOT file through LG Flash Tool 1.6 - Please help

Guys, I really need to find the LG DLL file database for flashing .TOT files.
The DLL file I need is for the LG G2 D80510B_00 or LG G2 D80510A_00 TOT file firmwares, to be used on 1.6 LGFlashTool, for Brazil unbranded variant of the phone. I believe it will work for all D805 models.
The .TOT file I intend to use is LGD805AT-00-V10a-724-05-AUG-23-2013-16G+0.tot
I have scoured the internet for over a week and found none other than in a chinese LG G2 forum, the link -- http://bbs.gaodi.net/forum.php?mod=viewthread&tid=662769&extra=page=1&filter=typeid&typeid=2381 -- and the file was no longer available for download. I registered on their forum, but the file was showing an error even after proper registration.
I have not found this DLL anywhere, is there a database for it? How did people come up with the AT&T and Vzn DLL versions? I haven't been able to extract it from the KDZ files either, and the DLLs generated from the KDZ during UpdateTool does not work.
I had bricked the phone originally by trying to use Scott's Clean Rom on it, and it bricked into fastboot mode. I flashed something wrong on fastboot, I can't even remeber what, and rebooted, and fastboot was no longer accessible...
I can get into download mode, and factory reset from stock recovery, no custom recovery available, it is gone. I try to flash KDZ files, many versions besides my D805 one, just for the sake of trying, but all of them get stuck on the 49% point. I have set up port 41, disabled modem, reset phone before trying, selected many different language combinations besides my own Portuguese one. Nothing works.
On LGFlashTool 1.6 it seems like it can work, but it errors at 1%, when I use the DLLs for D800 or D802. I need the DLL for D805. I even managed to find the proper TOT file.
I have also searched for about two days on how to reenter fastboot mode from where I currently am stuck.I even did a DIY Factory Cable on an micro USB I had lying around, soldered it all right, but it did not work, and the cable got very hot. I think these cables will not get G2 into fastboot mode, like it seems to do on Kindle fire and Motorola devices. Maybe my DIY was not that good, but I think it should have worked, I made sure the soldure was set and good.
I am downloading Android SDK to try to get back into fastbood mode from there, if there is a way, as it seems to be. I would try to reflash boot and other partitions in an attempt to fix my phone... Is there a way, or another faster path back into Fastboot?
Download mode does not show the version of the firmware on the phone in the box that displays information in the bottom while fdlashng KDZ files. It leaves a blank line where it should be. I believe it is part of my problem, that LGFlashTool does not see a version on the phone at some point, and fails. Or the phone rejects the PC pushes.
I am almost going to the tech support guy with a flash box downtown, but that would be my last resot, and then official LG support, if all else fails. I don't want to go to LG yet because download mode shows ROOTED in red, and they would see it probably, and my warranty become void.
Thanks for any ideas, guidance or help... Cheers guys.

Read this carefully may help you

Yeah, that was the guide I used when I landed on fastboot after a bad flash from CleanROM... I flashed some boot.img and recovery.img that didnt work out well.
After I flashed these I rebooted and fastboot mode was no longer loading, instead, I am now on bootloop of the LG logo, with no animation, just the first logo that shows on boot, and I can access stock recovery to factory wipe and also access download mode. My download mode shows rooted warning, and while I am flashing a KDZ, does not show the firmware version I currently have in the middle of the box - before I flashed those .IMGs, it did show the version.
I now a, after a .DLL for D805 10A .TOT file, and I cannot find it. I think the flash method from LGFlashTools 1.6 will work, with .DLL and .TOT files, where the LGFlashTools 1.0.5 did not work for me, with .KDZ.
Or if anyone knows of a way to get into the fastboot mode for G2, pelase let me know. Then I could reflash some .IMG files and hopefully get my phone back online...

Try to flash other version even this is 802 or internetional version. At least you can proof your phone completly brick or not.
I only have all TOT file link of F320 and D802 if you need to try.

It had to download, so I did it at a friend's who had 50Mbps internet house, to fix this.
I am sorry that I could not manage to do it offline. I even had the KDZ file to flash, but it was only possible through this option in LG Support Tool...
Best of luck to all in any similar problem, I know I was kinda without hope at some points. I spent 2 weeks trying to fix the phone.

Thanks to all that tried to help me! I appreciate it a lot! Thank you so much!
My only solution was to try short the capacitors following this thread:
https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
Thanks God I don't need to mess with the board!
My problem was that I tried this ROM LineageOS 17.1 with latest version of TWRP Blastgator. Everything was running fine until I flashed Magisk and installed some Mods, then the device rebooted and I get stuck at logo!
No System and no Recovery access, only Download mode! :crying:
Then I followed this thread:
https://forum.xda-developers.com/showthread.php?t=2432476
I used to install some custom ROMs like Cloudy G2, LineageOS, Resurretion Remix and AOSPX Pie and tried to this new one. I never had any problems!
This time I realized that my device was forever bricked, my last hope was to short the capacitors but I tried all ways to back to Stock because in Downlaod Mode my device was recognized by Windows.
I tried this in Windows 10 x64 but no success, then I formatted an old HD with Windows 7 x64 to try again!
Old Flash Tool get me stuck at 2% or 4%... no success in both system with all LG drivers available... NO SUCCESS!
https://forum.xda-developers.com/showpost.php?p=53313255&postcount=5400
LGUp only gives Unknow Device and never start but it's seens the device on port 41 - that I changed following the tutorial.
My last hope was New Flash Tool but I needed TOT file for my Device - D805 not D802 and the correct DLL. initially I didn't find anywhere... Like this guy:
https://forum.xda-developers.com/showthread.php?t=2583851
I give a lot of tries... a lot of different files, DLLs, tried .KDZ and .DZ, only errors and errors... a lot of "Failed to Load()"...
I'm getting frustrated until I see this thread:
https://forum.xda-developers.com/showthread.php?t=2582142
And found this mine of gold of Downloads:
http://downloads.codefi.re/autoprime/LG/LG_G2/
And again, thanks to all, there is a hope in the D805 folder!
I get the TOT File: BIN_LGD805AT-00-V10a-724-05-AUG-23-2013-16G.zip and tried the LG Firmware Extractor (https://forum.xda-developers.com/showthread.php?t=2600575) to get a new DLL (LGUP8974.dll).
And voilà, like a charm that WORKED!!!!!!!!! :fingers-crossed::highfive:
It installed Jelly Bean the with the Official LG Updater I installed Kitkat and finally Lollipop.
Later I'll try this LineageOS Rom again!
I hope I can help someone in need like me!!
I thank this forum a lot!!
And please excuse my English!
Thank you so much!

D802 no recovery after failed TWRP install on 5.0.2

i have experimented with custom ROMs on this phone in the past but have been using the stock lollipop 5.0.2 ROM for a while now after reverting back with a KDZ and so i figured i knew what i was doing.
i found out about the recent stability of cm13 nightlies on this device and wanted to give one a try so i decided to root the device with super su, which went well and then attempted to install TWRP with autorec for lollipop. It stated that the installation was a success and to reboot but when i did, it booted to a black screen.
i found this thread http://forum.xda-developers.com/showthread.php?t=2582142 which seems to say that i should be able to fix it if my device shows qualcomm 9006 in the ports menu, however my device shows up as marshall london HS-USB Diagnostics 9006, and i don't know what jellybean version this device was running so i dont know what images to use to to attempt this method anyway. I'm hoping someone more experienced with this **** that me will be able to tell me how to fix this. thanks for the help, King of Hard Bricks

try to see if skr tools works .. if not see in no download no recovery thread.. or post in back to stock thread.
not sure if that error is the one you need to short circuit your motherboard.. but search fisrt those places...cause i think somone suggested to do another step instead of the short circuit way..

Bricked LG G6

Hello everyone!
To make my problem short I tried to update my LG G6 on Oreo but in the middle of update process phone shut down(I didn't know why-probably battery?) And after that phone is bootlooping and I tried to flash stock rom using uppercut and LGUP but without success I manage to start flash process and when it reaches about 50% phone just reboots and flash tool gives error message. Now phone is bricked. I don't now if there are any solutions. Any help is appreciated! Thank you guys! :fingers-crossed:

Keep on charging..
See some post how to enter in download mode (within fraction of second).. use LGUP and flash PROPER ROM..
(I see it was bootlooping.. that it must be charging)

Huge thanks for your reply, well I manage to get to download mode without problem, PC can detect phone as well and I can start flashing process, however with all firmwares I have found I cannot "refurbish" because "refurbished is not supported by that firmware" so I can only select upgrade in LG up. When I start process it goes all the way up to about 50% and phone just reboots back to download mode, after that LG UP moves a few % further reaching about 55% and gives error " invalid response code". I think if I can somehow use that refurbish option to clean flash stock rom , maybe that will be the fix. Thanks again.

I also forgot to mention that when I failed to install stock room with LG up my phone cannot escape download mode, when I force reboot it phone goes again directly to download mode. Probably because there is no OS installed?

Are you sure to using right firmwares for your model?

Thanks for reply. Pretty sure I did use good firmware I found links here on XDA forums and downloaded "H8710d_00_OPEN_EU_OP_0327.kdz" but if I somehow found .tot file would that make a difference and let me to use that "refurbish" option. Thanks everyone for help, very appreciated!

Hi Ray, can you provide me the link of the tot file? I have the same problem

Unfortunately, I think there are no tot files that support refurbish. But after I replaced motherboard regular kdz update flash worked perfectly. I haven't found solution to that problem.
I would suggest you to try your luck if you have unlocked bootloader and try to flash TWRP to get phone back.
