Trying to downgrade, but KDZ_FW_UPD_EN not working - LG Optimus Black

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.

Pls move it to another subforum... Wrong here in DEV section...

Check if you have installed SUTL properly. It works as any windows application. second check if you have necessary admin rights on your laptop. You phone device should first be detected in the download mode as 'FIH' and should be visible in "My computer'. You should be able to browse thorugh and see the Image folder. If this is not happening check device manager on windows and see if your device drive has been diabled - Rightclick My Computer, Properties, Device Manager, On the top you will see "Qualcomm....", If it is diabled, right click and enable it.
Check in anoher laptop/desktop. I have had no issues with SUTL been installing stock using this now so many times...

Yes you need to rename the file to "firmware.nb0".
I think renaming the file to 'firmware ' is unnecessary while using SUT to flash a nb0 file... it is required for flashing thru stock recovery as far as I remember

My oversight !!!!...MI410 is right, not mandatory to rename the file to firmware while updating via SUTL - I have by default kept it renamed as firmware in my comp so that I don't miss out this aspect if updating via SD card !

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:

[Q] Please help unbrick LG if you know how to....

Hi,
a student in my class has bricked his LG 4x HD during ROM flash. He had asked around the Czech forum but no one gave a working advice, so I promised to ask here as I speak English better. Apologies if the same problem was handled here before, I'd checked briefly but didn't see it answered around. I'm translating from his Czech thread( http://androidforum.cz/post574659.html )
He tried to install Cyanogen mod 10.1, instaled APK, copied ROM and GAPPs into internal storage, switched off the mobile.... BUT instead of pressing power+volume down he pressed power and then volume down.(?) Now he's stuck on the LG logo. He took the battery out several times to no avail. He'd entered recovery menu, chose full wipe/factory reset with no result either.
Then he tried to follow the tutorial here http://forum.xda-developers.com/showthread.php?p=35971349 but after the "S/W Upgrade Please wait" screen he's stuck on the LG logo again. He said the logo was animated before but is just static now.
This is all I know, if this resembles something you'd seen before and got through, please share an advice. The boy - Mark - is 12, the mobile was his world, just got into waters too deep. I'm running WP 7.8 and my knowledge of android is limited...
Best regards from Primary School Ponikla, Czech Republic!
Hmm I've never touched any lg but if it is anything like a galaxy s2 then you are going to need an app called odin

Ok, than you can try this method:
http://forum.xda-developers.com/showpost.php?p=38838927&postcount=7 (LG Flash tool and .dz create tool u can find here http://forum.xda-developers.com/attachment.php?attachmentid=1642495&d=1358114024 or use all programs from first link)
Notes for this method:
1. You can make your .dz and .dll file for your region (IMEI) specific .kdz with this http://forum.xda-developers.com/showthread.php?t=2207786 or just use euro open .kdz from first link
2. For this and every flashing method if you have problem you need first check your usb cable, plug it in usb slot in motherboard not in front-pc case hub or similar, you need to provide space on your HDD (when using .kdz if you do not have hdd space kdz can not been unpacked for program that is using it for flashing)- maybe because of this your kdz flashing stop at 4%
3. Just to be sure - Your phone is LG P880 not LG P880G?
No, in cze its p880.

1. You can make your .dz and .dll file for your region (IMEI) specific .kdz with this http://forum.xda-developers.com/showthread.php?t=2207786 or just use euro open .kdz from first link
2. For this and every flashing method if you have problem you need first check your usb cable, plug it in usb slot in motherboard not in front-pc case hub or similar, you need to provide space on your HDD (when using .kdz if you do not have hdd space kdz can not been unpacked for program that is using it for flashing)- maybe because of this your kdz flashing stop at 4%
3. Just to be sure - Your phone is LG P880 not LG P880G?

Follow the steps one by one.
Unless your device is connected in a port higher than 16, using the "easy" way (forget about the device manager), you should be able to have comunication with the device.
View attachment 1927169
To be able to see it in the device manager you need to have your phone connected in SW mode to avoid mistakes.
No rush, take your time to read and understand the entire process.

Change USB, run as "administrator".
Some others had that problem, in front of "MODEL" you should see "X3"...
Some fixed it by changing USB. other running as "administrator", others changing cable...
I never had this problem. Might be related with the PC, I don't know.
You install "msxml.exe" right? and you turn ON "windows enabler"...
The Tool works well but, sometimes or, for some users, something wierd happends, and,
from out of the blue, they're able to flash without any problem...

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
