[Q] Stuck at LG logo no matter what I do.

Hello all.
Today mine optimus froze at LG logo screen for no reason, and its been like this no matter what i do.
I already updated it with the LG update tool on the emergency/recovery option, it downloaded a 368mb file and flashed into, but when I turn on the phone again it get stuck on the logo anyway.
I can't get into recovery mode either (vol down + 3d+ power), it ALWAYS get stuck on the LG logo.
Then I also tried flashing as mentioned here showthread.php?t=1540163 , it completes all the process but again when I turn the phone on it get stuck.
Anyone hane any idea? I'm about to throw it on th toilet

I had the same problem, deleted the drivers, tried again. Somehow it worked after a few tries.

I'm about to flash with the lg emergency /recovery for the 12th time haha.
I don't see how I will get anything diferent from the other tries.

I have the same problem after installing a Thiaiz rom.
Can you explain step by step how you recover from this issue?
Thank you

Are you sure you are flashing it right? Anyway try this.
Step 1
download
V21a from here:
http://content.wuala.com/contents/caroceiro/optimus 3d/roms/ORIGINALES/V21A_00.kdz?dl=1
or
V21d from here:
http://content.wuala.com/contents/caroceiro/optimus 3d/roms/ORIGINALES/V21D_00.kdz?dl=1
Step 2
download this
http://forum.xda-developers.com/attachment.php?attachmentid=887870&d=1328537753
Step 3
make sure you have installed your lg phone drivers before continuing to the next step
Step 4
unzip LG_KDZ_FW-Update_OfflineFix.zip
you will find a filename Automatic Offline Procedure.vbs
run it
if everything runs ok it will take you to the upgrade tool if not it will probably show you a windows script host error
if that happens try running it manualy from folder
LG_KDZ_FW-Update_OfflineFix
KDZ_FW_UPD_EN
KDZ_FW_UPD.exe
as soon as KDZ_FW_UPD.exe select Type: 3qct and PhoneMode: Emergency
select your downloaded kdz file , now you should take off you battery , press volume up and power on the phone , connect the usb cable and after 5-6 sec release the buttons and put the batery
Press Launch software update
It will take some time to decompress the files but if everything is ok it will start.
You will see the progress with various messages the last message ends with 0
That should do the job..

I will try this again but the links are incomplete!

Did it again, got the 0 on the end but still stuck at lg logo when booting it up again.

One correction: LG has removed v21D from their servers almost 10 days ago.

As I post above, I had the same problem.
The only way to solve it was go to the local LG support.
They verified that the phone (it was been rooted by me and the custom CWM installed) was in the warranty period and, without any questions in 2 days they put the phone in my hands as new with the acual gingerbread firmware. No costs for me.
Good service!

Yes. Lisboa/ Alfragide/Parque dos Moinhos. The assistance agent is "Mobile All" indicated to me by telephonic LG Client Support.
As a reason for the problem I said that when turned on the phone just don,t started staying stucked at the first LG screen.
EDIT: I had no CG till now.

OK i fixed the links although you already found the KDZ files.
Ok try this
remove your usb cable
remove your battery
insert battery again
press and hold volume down button
press power button
(you dont have to press 3d button thats for CWM Recovery)
after 8-10 seconds it will show you LG logo
release the power button and then the volume button
It will take you to the recovery menu
select yes
then again wipe EVERYTHING
ALL 4 OPTIONS
you can move with volume up and down and with menu key you run the commands
Good Luck

Got my fingers hurting after so many times i've tried it already.
Still stuck at lg logo.
I'm starting to think it is a hardware problem of some kind.

Doh, sorry for the noob act hehe.
Just flashed it again without the battery. It wen't all the way through 100%, didn't stop at 6% to put the battery on =/ guess what... Didn't work.
I will try it again to see if I hit the 6% stop. Worth a try.
I'm pretty sure I'm not skipping any step. I do uninstall every single time the LG drivers. Its pretty annoying.

Trying on a diferent computer right now.

I need help to unbrick my LG p920h Optimus 3D

I've tried to install Cyanogen mod then it was boot-looping already, so i solve this, but i could not use Cyanogen because of no signal, then i tried two original ROMS, anything works, i can't use that flash program because the link for bins are broken
My cellphone is a LG p920h as you can see, he is boot-looping, any suggestions ? :crying: :crying: :crying:

I bricked mine and used this http://forum.xda-developers.com/showthread.php?t=1491870 to unbrick. Skip to #3. Since I'm in the US, I use V20p.

Help with my optimus 3d
i have my optimus 3d rooted and i am not sure what i did, but when i rebooted it, all that happens is it goes to the rogers logo and keeps looping through that. it wont boot up past that and i have no idea what to do to fix it. PLEASE HELP ME!!!!

wipe data and cache, if you have CWM if not then try with factory reset(hold power+3D and press home, i think, google it to be sure how to factory reset the phone).

[Q] Bricked lg optimus one

Hi guys,
yesterday I put evoking (android 4.2.1) on my phone, and I wanted to change it, so I've installed ROM Manager..
After that, I've rebooted on recovery, but, the phone shows only the lg's icon..
So I tried to unbrick this whit KDZ (using this guide http://forum.xda-developers.com/showthread.php?t=883314) and, I tried all the possibility, but it still not working. Now, it does not turn on!! Can you help me please?
P.S. Sorry for the english I'm using google translate..

remove battery, plug the phone to computer while pressing vol up and power to see if computer recognize it, if it does, flash again via kdz
after reflash, restart and w8 for the phone to boot, it will take some minutes to boot, just be patient

It's all fine, this phone is unbrickable.
Flash ICS V30 European or V28B with FlashTool, there are guides on the forums.
Then if you want you can flash CM10.1.

i could suggest 2 problems, either you have "bricked" thee phone and you need to flash basically any bin file again or your phone is like mine and it fails on the first boot maybe you should try this, put in the battery and let it go to lg logo and the turn off after it has turned off plug in the charger (DO NOT REMOVE THE BATTERY) it might boot up, in this case you can installed custom loaders and recovery by using xbsa's recovery tool and then pressing volume up after you try the second boot (with the charger in)

Just do complete resurrection guide and you will be just fine.Just search xda for resurrection guide topic.

[Q] P920 reboots only into CMW recovery

Hey guys, I have a little or rather big problem regarding my LG P920. It only boots into CWM, but here the story:
A few days back I updated my phone to the newest version with the official LG Support tool. After this the performance of my phone went downhill. Scrolling, swiping, typing – all those things lagged and lagged.
So I decied to root my phone using this guide: http://forum.xda-developers.com/showthread.php?t=2366916
Everything worked out fine, I uninstalled some annoying system apps but found that the performance didn’t improve all too much. I went to the next step: custom ROM.
I used this guide: http://www.android-hilfe.de/anleitu...s-custom-roms-fuer-anfaenger.html#post5147071
It’s German, so I’ll try to describe what exactly I did.
First I flashed a ported ICS:
1. I Installed the LG Flash tool 1.2
2. I downloaded this ICS (http://d-h.st/QgU : XBSA404_AP.bin and XBSA404_CP.fls) and also the LGP920_110622.dll
3. I uninstalled the LG drivers and installed the CDMA drivers (version 4.9.4) to make sure the phone is listed as ‘LGE CDMA USB Serial Port’ and changed it to port 41
4. I then flashed that ICS (with .bin and .fls), got to 80% and finished
5. The ICS booted with no problem (only problem: it didn’t seem to recognize my German SIM, but whatever)
Then I installed a new bootloader and CWM:
1. I downloaded Omap4boot v1.25a (forum.xda-developers.com/attachment.php?attachmentid=1641950&d=1358098807)
2. And then installed the OMAP4430 drivers through the device manager
3. I downloaded the non-touch CWM v6.0.1.9
4. And then installed CWM using the ‘start_fastboot.bat’ from the omap4boot folder
After this I decided to flash CM 7.2:
1. I downloaded it from the official CM website and put it onto my SD Card
2. I started my phone into CWM using the button combination and made a backup first
3. I wiped data/factory reset and started to flash the .zip from my SD Card
4. At around 60% the progress bar got stuck at ‘Installung Update’ nothing happened for 30mins so I pulled the battery
5. I tried it again and again – no luck
After this is where it all went wrong (at least I think so)
I noticed that CWM gave me this error quite a few times: Can’t mount internal SD Card
I googled it and read somewhere to do a factory reset from the android menu.
So I restored my backup, rebooted into android, went into the menu and selected factory reset.
The phone went through some progress windows and then powered off and rebooted – into CWM.
From this point on I never got it to NOT boot into CWM.
I tried many things:
1. Restore backup again – no luck
2. Flash ROMS again (CM 7.2, 7 nightly, 10 nightly) – no luck (the installation actually finished, but reboots into CWM)
3. Flash stock ROM using the Flash tool (v21.e) – reboot into CWM
4. All kinds of combinations of wiping/formatting data/cache/dalvik/system/batterystats etc in CWM
5. This guide http://forum.xda-developers.com/showthread.php?t=1942836 and the rebooter tool mentioned at the end
6. Using the official LG Support tool to reset upgrade errors – stuck at 4% of installing
I saw another post which suggested to flash universal_recoveryloop_breaker.zip, but this apparently didn’t work and got the phone stuck at LG logo – should I even try it?
I saw other post with similar problems but always another model –p925 or p720 and not much information given about what they did, that’s why I went into detail and hope to find a cure
I saw drastic00's guide here http://forum.xda-developers.com/showthread.php?p=39269819 suggested a lot but wanted to post this first before I try a second guide that might only make things worse.
I spend the last few days in front of my PC and phone but nothing worked – I’m starting to go nuts..
I am willing to try everything, to provide any information you might need to help me figure out how to fix this.
Thank you for any help provided – it is greatly appreciated

If stuck at LG logo try factory hard reset.

Try dreccons recovery loop breaker

It's not stuck at the LG Logo, it boots into CWM and I can go through everything and do everything in CWM.
Would you suggest I try your guide first or try hard reset? If your guide - what exactly should I do, where be cautious? And how do you perform a factory hard reset?

I saw this being suggested in this thread as well: http://forum.xda-developers.com/showthread.php?t=2441478
But when he wrote that after trying that he didn't even get into recovery anymore I got scared

You said you flashed and it sticks at LG logo. If you are flashing the correct files, not a wrong binary, factory reset should fix that.
Can you enter download mode? i.e. hold vol up, connect usb to pc, insert battery. You should see "S/W". If not you might need xbsall's or Karim Kahale's unbrick guide. If you DO have download mode, you can just flash as in my guide. But I can't stress enough that drivers must be installed to pc correctly.
Ported ics is old and from the Korean device. Could be cmod is not compatible, dunno, but that could be the issue. In that case you may have a 'hard brick.' Wrong ROM with wrong firmware.

Wait so did u flash recovery loop breaker or not? I am confused. If not flash it. It will delete your recovery then you got to flash another but worth it

I have never had recovery loop, so yeah, you might try what Niko says first.
Flashing will redo your OS, etc. but if you have just a recovery loop you may not need to start over from scratch...

Sorry for the confusion: I didn't try to flash recovery loop breaker. I just saw another thread in which a guy had a similar problem to mine, someone suggested he should try loop breaker, he did and atferwards his phone got stuck at the LG Logo, that's why I hesitated to try this.

I don't know what exactly I have sorry, this is my first time rooting, flashing and all that.
The phone only boots into recovery. I can flash other ROMs, I can restore backups and do everything else in CWM, but when I reboot I get booted into CWM again.
I was hesitant to try the loop breaker, because I saw the other thread, but I will try it this afternoon and tell you how it went.
Just a quick question: what if I end up stuck at the LG Logo afterwards?

Update:
I flashed the recovery loop breaker and flashed CM7.2.
When I now start the phone the LG Logo appears for a few seconds, then a white screen with small dots/pixels comes up and the phone is stuck there..
sooooo.. i think this is not good.. right?
I started to prepare for drastic's guide, downloaded all the files and will do that tomorrow or the day after, or would you suggest something else I should try first?

I have never installed cmod so I don't know.
You can follow my guide if you want. Like I say, drivers must be installed correctly and you must pay attention to details.
Doing random things is not going to help you.

Why do u want cm 7 anyway? if I would want CM I would go for Cm 10 (my current rom lol) and If i would want GB i would one with 3D support

The loop breaker said to flash a new ROM afterwards, CM7 was the only thing I had at hand, so I tried it.
Right now I don't really care which ROM I flash, I just want to use my phone again :crying:
I'll try your guide if you don't have other suggestions so far, let's hope I don't end up in a recovery loop again - this is driving me mad
I will keep you posted on how it goes with your guide or if I have any questions. Thanks so far !

:confused?: So after you flashed loop breaker what exactly did you do? After flashing loop breaker u need new Recovery not ROM if you reboot and try get into recovery which is not there you gonna end up at lg logo. Is that what you did? Anyway if you do follow drastic00's guide you should be able to revive your phone..TWRP Recovery is integrated in xbsa rom (am I right drastic00? not sure) I would recommend you try xbsa v8 first then you can decide if u want different rom
Also drastic don't want to bring my stuff here but you know what I said about weird startup screen ? He probably got the same thing he said he sees white screen with pixels and dots . Still no clue what could be reason?

I have not had this particular problem so I don't know what could be the cause.
Flashing xbsall's v28B rooted ICS should recover the device as long as the phone can enter S/W mode. Yes, it has built in TWRP recovery, but it resides in system partition, not recovery partition. Any old TWRP backups you may have are probably not compatible with this method of custom recovery, so keep that in mind.

You will have a recovery loop when you try to factory reset your device using the soft reset like this
Settings>Backup & reset>factory data reset
Dont do this if you have custom recovery
To do a factory reset use cwm/twrp and choose wipe data/restore to factory setting
---------- Post added at 03:25 PM ---------- Previous post was at 03:18 PM ----------
And to recover on this thing you have to reflash a stock firmware using kdz update or lg flashtool.
I cant provide you links. Im on mobile use. Try to search on forum. Im on mobile use

This is exactly what happened to me. I will try drastic's guide now, it uses stock ROM at one point if I'm not mistaken. I'll keep you posted what happens. Thank you!

It worked! My phone boots normally and everything is fine, yay :victory:
Thanks for all your help, now I just need to explore everything in this custom ROM
Is there a explanation or guide of all the apps in this ROM? I've installed XBSA v8, maybe I'll upgrade to vR3D soon, how much better is it?
Edit: On a second thought...
THIS ROM IS BASED ON CANADIAN ROGERS V30C AND IT HAS NATIVE SUPPORT FOR ENGLISH, FRENCH AND SOME ASIAN LANGUAGES.
IF YOUR LANGUAGE ISN'T ONE OF THEM YOU MIGHT HAVE PROBLEMS WITH SMS NOT BEING DELIVERED CORRECTLY IF IT'S WRITTEN TO ANY OTHER LANGUAGE.

I think I'll stay with v8 then

Check xbsall's page for ROM details, linked at the top. :thumbup:
