got an s/w upgrading screen loop.

hello guys, i need help on my o4x, actually i've failed to upgrade from v10c to v10f so each time i turn on my device it just looping on the s/w upgrade screen, thanks for advance, i really need help cuz this is emergency T_T

just enter recovery and do a clean factory reset
turn on mobile while holding VOL- down until it shows recovery, select "wipe data/factory reset" and reboot.
and you should be all fine.
if you installed clockworkmod and did a full back or used titanium to backup apps, you could save all configs, so try that for next time.

You should search a little more "how to flash", "how to unbrick", etc... I think that almost of the possible problems with "bad flash"
were already posted somewhere.
Just to avoid people being repeat over and over the same

You need to press the VOL "--" and the button switch on the phone, and hold up to vibration. Thus enter into a mode of CWM. If this does not help, then update the firmware through KDZ, the data is stored.

If u want to start from stock recovery in CWM-Recovery u can use adb, see http://forum.xda-developers.com/showthread.php?t=2006168

No need to wipe or do a factory reset...just reflash firmware through KDZ. And you should be good. Then just re root after.

Looks like your file system is corrupted, making impossible to re-install the factory settings
Just re-flash the phone...
Downgrade to V10A, factory reset and upgrade to V10H "web upgrade".

Your problem is solved very simply. You just need to make the output of KDZ when iParam stop at 204 , then insert the battery, to come again in mode S/W Upgrade and re-install the firmware . Run KDZ and re-install the firmware. Believe me helped. Sorry for my bad English. My skype: Feodorus1972.

LG-P880 Firmware flash,upgrade,downgrade improved.

So as LG-P880 flashing instructions were too much hassle for my taste
Here it is a very simple way to upgrade/downgrade your phones easy peasy
Everything will be gone so backup first!

Mirror 2:
http://www.mediafire.com/download/wu50af8uh99air7/P880-Flashtools.rar
Unrar and copy your downloaded new firmware inside LG Flash Tool 2014 folder
Browse to Driver folder and install/double click LGUnitedMobileDriver_S50MAN311AP22_ML_WHQL_Ver_3.11.3.exe file.
Shutdown and remove SIM&EXTSDCARD from the back of the phone. Leave battery in-place don't take it out.
Press and hold Vol(-) connect usb cable coming from pc->download mode
Run LGFlashTool2014.exe
Selections
CDMA or 3GQCT doesn't matter really
DIAG
KDZ file location
then select preferred flash mode
Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.
Done, enjoy!
Update:
If you get
This mode is for data backup at service center ...

in recovery repeat flashing the KDZ and you will get the stock recovery this time.

Wow, thx Demetris, you are my savior just in time.
With the online upgrade the phone is always stuck in a bootloop and the old offline method just didn't work as it gave me a file extract error, although I know I've done everything correct (maybe the issue was leaving the sim and sd card inside or selecting 3GQCT?)
Btw and fyi, the CSE method is only available if CDMA is selected.
Thanks for making this fast and simple tutorial that even works ^^

Thank you for the great tutorial. I tried exact accordance with my LG-P880 to update. Unfortunately it did not work, the device starts but then remains at the LG logo, no further reaction. Restart / reset no improvements. Options in Android System recoveryy <3e> do not work. Do you have an idea how I can still save my beloved P-880?

Use CDMA and select CSE flash. After update and phone sticks at lge logo remove battery hold vol +(99% of times you need to use - but for me was +) and press power on. On stock recovery factory reset and now phone will boot

I did and the unit freezes. The figure Android is flat and shows an exclamation mark.

Did you erase nv partition? from stock recovery?
If not check this V20c md5: 8dd721c1c6ec63c74d42b2931de8456f

KDZ
where can we find the original KDZ files?
Thanks in advance! :highfive:

For me it worked without a factory reset, just flashing and restarting.
Forget what I said, i think I did a factory reset and wiped nv partition before I flashed the new firmware with this tutorial.
@alberteske all firmwares can be found here: http://lg-phone-firmware.com/index.php?id_mod=15
but some links are broken, after clicking on a link you have to replace the "%2F" at the end of the adress with a "/"

When I select the options in the recovery mode it freezes, no action will happen.
The MD5 number is correct.

baseband change without flashing whole kdz?
isn't a way to extract the baseband files and flash them without having to flash kdz + unlock + re-install everything...?
thanks a lot in advance Demitris!

Think here you mean:
press and hold [vol -] and [power] until you got the "android recovery figure"
then clear cache and make factory reset

Somehow my phone got to the LG logo but is in bootloop. Tryed vol+ and power. I can get to stock recovery, but how to factory reset from there?

Reboot phone
ADB sideload
Factory reset
...something like that
I think that you must see that options when enter recovery(vol- and power button),then using volume buttons select factory reset and confirm with power button. I also have bootloop after flashing kdz but after factory reset phone boot properly.
BTW i use flash kdz tutorial not that method from Demetris

[Help] Unlocking bootloader D-405N

I use this guide: http://forum.xda-developers.com/lg-l90/general/guide-unlock-bootloader-flash-custom-t2839690
But I cant find recovery.img on my phone and I use another recovery. Now I want to go in Recovery Mode but I have only LG logo and in left up corner is:
[490] fastboot_int()
[590] USB init ept @ 0xffdc000
[610] udc_start()
Besides when I restart phone, my phone turn on normally. I think that the fault of a bad file recovery.img. Someone can send me recovery.img on D-405N? Or help me with this problem? Best Regard, Damian.

all of them, its for all lg l90 D4xx devices.
I recommend using this one TWRP_2.8.4.0_160115_L90.img

Ok It's done, thank you. But i have another problem... I put on my SD card ROM but Team Win Recovery Procjet doesn't see zip file. Why? SD card must be in Ext2?

sd card should be in fat32
make sure you are looking into right directory, in twrp you can choose between internal and external sdcard. if you cant see it on external memory try putting it into internal.

I have another problem... -.- I install ROM but when i turn on phone is LG logo, T-mobile logo and I wait and nothing. Someone can help me?!

which rom did you install?
maybe try to do full wipe and reinstall it

just pull your battery out
and this how you can get into recovery, its from that thread for unlocking bootloader etc
HOW TO BOOT INTO RECOVERY PRESSING VOLUME AND POWER KEY
You can reboot to recovery via flashify app or following key combination: -
Power of your phone press both Volume Down + Power Button same time, As soon as the LG logo appears release both buttons and immediately press and hold same buttons (Volume Down+Power) again. Now Factory data reset screen will appear saying "Erase all user data & restore default settings?". Use volume down key to select "Yes" and press power button to confirm and now you should be in recovery.

[Q] DBI Apps Watchdog Reset I can't do factory reset or go to recovery

(Sorry for my eanglish)Hi gyus. I broke ma phone, but not totaly. I just want to install cyanogen, so I do much things on phone, but all of my guides are in Polish. I can paste it here but i don't think it will be helpful. So I install revowery TWRP from XDA using aboot v10b when I have v10f system and flashify, but i can't install CM. So i downgrade my system to 10b and than i install recovery. Showed up purple screen, so I turn phon on in download mode and by LG Mobile Support Tool I install oryginal system. Now I can use phone, but I cant go to recovery or do factory reset. When i wan't to do factory by kesy combination vol- + power i can see "Factory Reset Processing..." and after that only black screen. When I wan't to go to recovery by flashify I can only see
DBI Apps Watchdog Reset
DmiGod Crash Handler: DBI Apps Watchdog Reset
Option: SD card ram dump mode.
Push below files to sdcard before test.
rdcookie.txt, rtcookie.txt
Please do following action
1) Ram dump Mode. Please connect USB.
2) Get the ram dump image using QPST Configuration.
3) If sdcard ram dump enabled just wait for reboot.
4) Collect ramdump files from your pc to sdcard.
5) Send e-mail to [email protected]
What I must to do now?

Like you said:
"LG Mobile Support Tool I install oryginal system"
If you flashed the KDZ with LG support tool you don't have a custom recovery now, so your phone doesn't boot to it because it's locked.
You must root, unlock bootloader and install a custom recovery again.

my phone screen is purple with a written white letters: "DBI Apps Watchdog Reset" among other writings as well. What I have quefazer to be able to use it again?
My mobile phone is a L40
