Trying to downgrade, but KDZ_FW_UPD_EN not working

Hi Guys, i'm trying to downgrade the phone from 20B -> 10C, however after I launch the KDZ_FW_UPD_EN, selected the V10C_00.kdz, click start upgrade, it comes out LGmobile Support tool page and says the phone already has the latest firmware. Any idea why it not start flash the firmware?
I tried on another computer also same error.
Thank you.

if u want to downdgrade from 2.3.4 to 2.2.2 you can use SmartFlashTool_External, download this one: http://www.multiupload.com/MBRIAUG5V2 (is 2.2.2 european version) and connect ur smartphone in flash mode (turn off, remove ur battery, press volumen up and connect to ur computer) then open smartflashtool, select ROM Copy D/L, select Normal mode, in CP bin u have to select one of the two files result of ur .rar from multiupload i gave u with extension .fls, in AP Bin u need to select the file with extension .bin, select in comp port the only port it ll show, in comunication driver u have to select LGE Mobile USB Serial Port in Communication Driver or similar, and then click on start. There u have, ur smartphone will downgrade satisfatory, then u can do root, then rom manager and then cyanogenmod with nova kernel =P
sry about my english, i just want to help u some way =P

Thank you. It works after using SmartFlash tool.

OK, lets do it...
First you'll need the .kdz file. The firmware to flash it. Click here: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP880/ANLDWH/V10F_00/V10F_00.kdz
Next, the programs, here: http://www.4shared.com/rar/Re4VCOAS/kdz-update.html
Assuming that you already have the LG drivers installed...
1 >>>>> copy the V10F_00.kdz to the folder that you download (kdz-update).
2 >>>>> install "msxml" from the "kdz-update" folder.
3 >>>>> run "Windows Enabler" from the "kdz-update" folder, it should appear an icon on the right/bottom of your screen, if not near the others in the taskbar, you need to click on it and you should see "ON" on that icon.
4 >>>>> run "UpTestEX_mod2_marwin" from the "kdz-update" folder.
On the field "Select type" choose "CDMA - SmartPhone(WM)" (if the flash fails change it to "3GQCT - SmartPhone(WM)")
On the field "Version" (at the left) type "V10F_00".
On the field "Select model .dll" browse and select the "P880.dll" from the "kdz-update" folder.
On the field "PhoneMode" select "EMERGENCY".
On the field "Select kdz file" browse and choose the "V10F_00.kdz" that you download and should be in the "kdz-update" folder.
5 >>>>> with your phone "OFF" and the USB cable connected to the PC, press "VOL-" and connect the cable to the phone untill it turns "ON" in "S/W Upgrade".
6 >>>>> Now click on "Start Upgrade" in "UpTestEX_mod2_marwin". As soon as you see some progress in the log, put the battery on the phone, carefull to don't let it drop.
Wait until the phone reboot by it self and it should be all.
Let us know if it worked or not and, or, if you have any other problems.
Good luck!

The phone boots up but stucks at the lg logo. With 'select type: CMDA (smartphone wm) the log stops at '13:41:32 : 3GQCT : wParam = 2001, lParam = 0'. It never says complete. And with 'Select type: 3GQCT (smartphone wm) it gives an unpacking error.
Its very anoying.

Forgot to tell you, everytime you need to use the flash tool you need to close it and restart it again.
That unpacking error is because of temp. files. The program unpack the kdz file to another one where is the .dll and the .dz, doing that twice it uses to have that error.

What RuedasLocas said is correct however this:
On the field "Select type" choose "CDMA - SmartPhone(WM)" (if the flash fails change it to "3GQCT - SmartPhone(WM)")
Isn't. Keep the phone type set to 3GQCT.

@judodave, try first flash the V10A version.
My first flash went wrong and I was going crazy around the V10C and only after I flash with the V10A I was able to re-flash with the V10F.
Maybe it works with you to... at least I hope so.
Here is the link: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP880/ANLDWH/V10A_00/V10A_00.kdz
I'll flash mine (later of course) just to post a damn video of how I do it.
Good luck once more.

You'll do it. From time to time someone appears with a phone like yours. For sure is something escaping and we just don't figure out what it is.
When we start to do the same thing over and over again, we use to forgot some small procedures.
Don't worry, one of these days you'll make it.

Thanks.. it works. I just upgraded my lg p880 from v10e to v20a two days a go. Then i rooted the device. Works for two days, then it stuck at boot logo after I restarted the device. Do not know why. So far has been disappointed with the battery performance and the sound quality of this device. Hopefully the new v20a can help improve even just a bit:good:

VERIZON ONLY Revert to stock GUIDE [UPDATED]

MAKE SURE TO VALIDATE THE DOWNLOADED FILE with the md5 hashes listed under the links you followed for the tots.
You can use this to check It will add a tab to the Propterties" window for any file. Check that your MD5 matches the ones pertaining to your downloads. There is an MD5 listed for each download for the zip file, and for the tot included in the zip. If the TOT MD5 matches then you are fine. We only included the zip MD5s so you can quickly check as soon as you finish downloading. Repeat: MAKE SURE THE TOT FILE's MD5 MATCHES THE ONE LISTED UNDER THE LINK FOR "tot file md5". If it does, you are good to proceed.
-------------------------------------------------------------------------------------------------
1) Go ahead and put phone in Download mode by VolUp + plug in USB to PC. At this time your computer should install the device, if it hadnt already. Open device manager to check if un der "Ports (Com and LPT)" it shows up as LGE AndroidNet for VZW USB Serial Port (COM##) IF the COM number is anything other than 41, which it probably will be. Right click it in device manager and choose peroperties, then go to port settings tab and click advanced. On the bottom choose COM41 and hit OK. (if you get an error about it being in use I'll write more about that later)
hit ok and all that and close out the properties.
2) Open LG Flash Tool
You may get a menu asking ??? Korean something, choose that one hit OK.
Now in here you have to choose "Select Manual Mode" checkbox on top then on the top DLL box choose the "LGVS980_20130902_LGFLASHv151.dll" we saved earlier, then in the S/W box click add and choose your TOT file. MAKE ABSOLUTELY SURE ITS THE RIGHT ONE
Then hit OK.
3) Now click the yellow arrow in the top left of the main window. It will prepare and maybe give a milky way error (seriously) ignore it until it says finished, or ready.
4) Now unplug your phone, power off and then go back into download mode again, volUp+USB. It should immediately connect and start flashing.
It will restart around 83% and then you are done!
if you red light is flashing on phone just unplug and hold middle power until it either boots or turns off so you can turn it back on.
Done!

I want to stress that this guide was written with only Verizon variant in mind, while it may work for others Id appreciate not flooding this thread with requests about other variants.
Yes, this guide can be useful for them, but stuff will be different. I don't know what, and I don't care. Please don't post in this topic if you have issues with another variant, you can always start a new post, or join another one for that.
IF you wish to request me to write a guide for your variant, then please acquire links to all required resources, tell me what's different, and I'll put together a guide for you. Until that happens, no off-topic posts in here PLEASE.

Trying this out right now. Really fast download speeds, thanks so much! I am doing this to get rid of the Chinese root and try the new one. Then I'm gonna uninstall/debloat TO THE MAX because I know I can always go back to stock :laugh:
EDIT: Everything went smoothly, and quickly too. Settings says "unrooted" but not for long hehe.

Worked like a charm, thanks for the good stuff.

This is the error that is ok to get?
"MilkyWay Control Port open fail"

Didn't work for me.
Using Windows 7. On device manager, it just says LG Phone. Not LGE AndroidNet for VZW USB Serial Port (COM##).
And I can't install the drivers; when I indicate the file the drivers are in, it says nothing is found.
Even though that step didn't work, I went ahead and continued with the steps. The LG Flash tool stuff worked. After "Ready", I unplugged the phone, but it stayed in "Firmware Update" mode. I long-pressed the power button and it powered on. I then turned it off, went back into download mode, and it's not flashing anything.
There is also no "port settings tab" in the device manager for the LG Android Phone.
And when I click on the LG Android Phone in device manager, under drivers, it says there are none installed. I tried installing the driver in MTP mode, but it says all drivers are up to date.

I'm gonna sound like a pain, but does anyone possibly have the ROMs tot file hosted somewhere else? Both host sites are blocked for me while at work. No prob if they arent, I'll just wait till later. Thought I'd ask.

I can tell you that when Verizon did this on their machine it still didn't change the About Phone, Status, Rooting status to "Unrooted". It stays at rooted if the phone has EVER been rooted. Even when I went back to unrooted the status still says rooted.
Did you have different results?

You should be in download mode when installing the drivers, and install from the EXE, dont install from device manager, unless you want to extract the EXE's contents and find the driver ini files, that wont work.
Also if it still fails on you, right click the LG phone in device manager, and choose uninstall, reboot, install EXE, then plug in phone directly in download mode. And tell me what happens. I'll try to help ya out. Maybe join #lg-g2 on freenode to get some more help?

Yup, that's what I got. After that error, and it saying finished, make sure to unplug and replug your phone back in in download mode, and make sure your device is showing up in device manager under COM ports as COM41
If you are still unsucessful, join #lg-g2 and ask in there or ping me, as I'm sure you want faster help than forum replys can get you

I did. My root status went away until I rerooted with IOMonster's rooter. Both on the download screen and in about phone.

I am not a developer, I simply decided to write a guide out of the procedure they led me through.

I'm gonna sound like a pain, but does anyone possibly have the ROMs tot file hosted somewhere else? Both host sites are blocked for me while at work. No prob if they arent, I'll just wait till later. Thought I'd ask.

Blocked? ... why is my site blocked at your work?
That's not good... does it give a reason for the block?

I dont think it's anything for you to worry about. My work blocks a lot of hosting sites. However, the reason just says "Uncategorized"
Good thing is that theres a button I didnt realize before that bypasses the block... :laugh:

So were you able to get the files? If not, I can copy them to another of my servers for you.

Didn't work for me.
Using Windows 7. On device manager, it just says LG Phone. Not LGE AndroidNet for VZW USB Serial Port (COM##).
And I can't install the drivers; when I indicate the file the drivers are in, it says nothing is found.
Even though that step didn't work, I went ahead and continued with the steps. The LG Flash tool stuff worked. After "Ready", I unplugged the phone, but it stayed in "Firmware Update" mode. I long-pressed the power button and it powered on. I then turned it off, went back into download mode, and it's not flashing anything.
There is also no "port settings tab" in the device manager for the LG Android Phone.
And when I click on the LG Android Phone in device manager, under drivers, it says there are none installed. I tried installing the driver in MTP mode, but it says all drivers are up to date.

Turn your phone off. Then hold vol. up as you plug in a usb cable. This will send you to download mode, and the proper device should show in device manager.

GREAT job on making up these instructions on the fly like that bro. I got tired last night and did it this morning instead. Instructions were absolutely perfect. :good:

WACOMalt said:
You should be in download mode when installing the drivers, and install from the EXE, dont install from device manager, unless you want to extract the EXE's contents and find the driver ini files, that wont work.
Also if it still fails on you, right click the LG phone in device manager, and choose uninstall, reboot, install EXE, then plug in phone directly in download mode. And tell me what happens. I'll try to help ya out. Maybe join #lg-g2 on freenode to get some more help?

Ok, it appears to be working, thanks!!!
It has been stuck on 8% for a while, though, maybe 2 minutes. Is that normal? Is this a pretty lengthy process?
EDIT:
Still stuck at 8%. Getting worried. . . .

OK, this is a new one for me... You ARE on verizon LG G2 right? Might need to check the MD5 of that tot file. I'll update the guide with that step.

Does this revert back method wipe data?

Yes, I'm on VZ LG G2.
If I disconnect and reboot my phone, am I screwed? Checking the MD5 isn't going to help me at this point, I'm afraid.

Hello, I have the following problem. As in every other thing ive done to this phone (root, installing twrp, installing xposed) I always thought my model was LG-H502F. Though, my model is LG-H500F, I bought it from Greece, I recently bought Huawei P8 lite 2017 for myself and I gave my old LG to my father, he tell me that sometimes it lags and he is right. I think it lags because I uninstalled Xposed (flashed the uninstall zip using twrp) and also removed root, because he didnt need those things in his phone. The question is: Is there somewhere I can get the stock LG-H500F zip and what guide should I use? Ive been searching for a while now and can't find many topics related to LG-H500F. Thanks
