Hard reset cant restore Factory setting

Hi all,
what can i do?

You sure that what you're trying to perform is a hard reset, not a mere soft-reset?
If yes, this is really weird. Try flashing your ROM again.

If you are trying to perform a hard reset and it doesn't work and phone won't reboot, then only other option you have left is to put phone in bootloader and flash stock/cooked rom.
Does phone reboot ok? Are you actually performing a hard reset i.e. turn phone off. Hold down vol up & vol down and then phone on while still holding down vol buttons. You will then be presented with a white screen with text asking you to press vol up once again to restore factory settings.

If it doesn't help try to flash a cooked or stock rom but I recommend you to first try the hard reset.

Bootloader is the tri-coloured screen you are getting
If you can get phone in bootloader then you can still flash new rom.
First of all try a hard reset by doing the following:
1. Turn phone off
2. Hold down vol up & vol down
3. Continue to do No.2 and turn phone on
4. You will then be presented with a white screen with text asking you to press vol up once again to restore factory settings.
Once complete if phone still doesn't reboot you will need to flash new rom by doing the following:
1. Turn phone off
2. Hold vol down button only
3. Continue to do No.2 and turn phone on
4. You will be presented with bootloader screen (tri-colour screen)
5. Connect phone to pc and bottom of screen text should change from 'serial' to 'USB'. If this doesn't read cRaCKwHoRe's guide (see link below) as you may need to update pc drivers.
6. Now flash original stock rom from which you have downloaded from wiki. You can find stock roms here. To flash rom you will need to run ruu file from pc (this is rom you have downloaded)
Make sure you only flash original stock rom which was already on your phone. If you want to flash other roms you will need to follow cRaCKwHoRe's guide
I'd recommend reading the wiki so you understand more about the process and you phone
Good luck and keep us informed

Unable to enter recovery mode after removing a system file by accident

Greetings. I ran into a major problem yesterday when i was playing around with titanium backup. I was a bit careless and touched some important system file. After which i was unable to reach the home menu nor restore the backup file. I rebooted and pressed the volume down button, and the "updating system.." icon appeared. Nothing happened for 1h, so i tried using the lg software suit to do a remote recovery. Nothing worked. I tried performing an update, hopimg the particular file might be restored, but the updater told me the new version is incompatible.
I'm a bit inexperienced in these matters, but i find it impossible that the bootloader could become permanently inaccessible due to a software error. I need to restore the original rom without accessing recovery mode on the phone - but how?

You're right, it's not possible.
You're trying to get into recovery wrong
Hold bother power and vol-, not just vol-

Thats what I thought I did, I always hold the power button until the boot screen appears. Still no improvement, seems I wont be able to restore my phone to factory default through normal means.

If you let it try and boot up, you might get it far enough to use 'adb reboot recovery'

If you ask me, the best solution is to flash the stock rom > root > restore titanium backup

As I said, there's no way I can reach any system menu whatsoever. The phone freezes at the LG logo on a normal boot, and in system recovery it freezes at "S/W Update". I can't do anything using the manufacturer's PC software, so what do I do? The rom is obviously rooted, but I'm not the one who performed the job so I don't know which software was used for that.

Try "factory reset". Press "Vol-" + "Power" button, select "wipe data/factory reset", press Power" button, select "Yes -- delete all user data" and press "Power" button again.
If it doesn't works, re-flash the phone.

Yep LG does not like you to change their fonts. I have tried and the system jumps into a reboot loop.
I even changed the fonts and named them the same name as the LG fonts. Still same problem.
Just reflash the kdz.. You can find information in one of the threads. Search and you will find the answer.

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.

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.

isn't a way to extract the baseband files and flash them without having to flash kdz + unlock + re-install everything...?

ok.
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

[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

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?
