Stuck at LG animation

I have a GT540 stuck at the LG animation. I had Cyanogen 6.1.1 which I didn't really like (was having some big issues with it), so I flashed a 2.1 ROM and now I'm stuck.
I have tried:
* disabling LGE Modem in device manager, rebooted laptop and phone, reconnect then flash
* booting boot into fastboot mode - screen does not go black, stays stuck at lg logo. Fastboot commands leave <waiting for device>
* using ADB while phone stuck, error "device not found" - same in download mode
* booting into safe mode with home+power button, phone stops at animation still
* flashing using KDZ in all 3 modes both when the phone is stuck and also in download mode
* flashing using the KP500 updater as described at hxxp://android.modaco.com/index.php?showto...t&p=1394990
* flashing using LG mobile support tool recovery option
* reinstalling LG drivers
* flashing with phone in download mode through LG Mobile Support tool in recovery mode, error "No software update available for this device"
* connecting to the phone through hyperterminal to do a factory reset then flashing
* some people are reporting this problem with a corrupt SD card. Removed SD card, still having this problem
* removing battery, connecting USB cable (displaying phone with arrow screen) and flashing in all 3 KDZ modes
* booting download mode by removing battery and holding VOL- while plugging cable in
I can't find ANY more ideas no matter how hard I search. I've been trying to fix this for 2 days solid now and I seem to have tried everything.
Halp!

Did u tried to flash Quarx black ROM ?

I've flashed Vodafone 2.1 official, Baltic 2.1 official, French 2.1 official, a 2.1 with fastboot, and Clockwork Recovery 2.1... also out.kdz as mentioned in this thread hxxp://forum.xda-developers.com/showthread.php?t=825173&page=3
I'll try the Quarx ROM now but I don't like my chances
EDIT: out.kdz in the thread above is the same ROM as in the quarx black rom thread here hxxp://modmymobile.com/forums/527-lg-androids/557934-gt540-rom-black-system-rom-quarx.html so yes, I've already tried that ROM.
I've logged a service request with LG but I REALLY want to get it working without waiting a week or two for them to get to it...
thanks
EDIT #2: I CAN access the phone using Hyperterminal on COM12 (tried a hard reset that way) but I have no idea what commands exist or anything through that terminal...

When you tired to flash a ROM with fastboot what happened? still stucked @ LG logo

I can't do anything with fastboot - if I hold camera+power it won't give me a black screen, it just gets stuck at the same spot (last frame of the LG animation, white LG logo)
I tried running fastboot commands in this state but I just get <waiting for device>
EDIT: I've just re-flashed the quarx ROM but getting the same problem, camera+power hangs at the LG logo and fastboot reboot just sits there with <waiting for device>
I was wondering, is there any way at all to install software through a hyperterminal? This seems to be the only connection method that works (adb doesn't work either). I followed these instructions to do a factory reset and it worked:
In Hyper Terminal type
AT
OK --> if youre getting OK, then connection with your device is OK, if there is no OK, check again your PORTS
if you get OK, the type
AT%FRST
FACTORY RESET OK --> this will perform factory reset to your device, it might fix your problem but it might not

It didn't fix the problem, but I was able to connect and successfully perform the reset so at least that connection works... Maybe I could erase the system and then try flashing in cs_emergency mode or something?

1. Remove battery,sim,mmc coonect ur phone to pc using USB cable
2. Press Volume down + power when it boots
3. It should go to download mode now
tell me whether it is going to download mode or not

It goes into download mode when I do that, I've tried flashing in DIAG, EMERGENCY and CS_EMERGENCY modes this way with no success.

20B FAST
Try this: flash it in normal mode with KDZ updater.
Then when flash is finished enter in fastboot mode ( in this ROM flashboot is not black screen, it is blue screen with white letters) so you can easy see when you are enetered in fastboot.
then
fastboot -w

We have liftoff!
Booting the phone normally I get the LG picture, LG animation then loop at the android animation (one step further than I was getting before...)
Phone booted into blue screen fastboot mode and fastboot commands work (fastboot -w, fastboot reboot etc).
fastboot -w gives the following readout
fastboot: processing commands
fastboot: erase:userdata
skipping @ 3215 (bad block)
cannot erase @ 3215 (bad block?)
fastboot: erase:cache
Click to expand...
Click to collapse
Best of all, the phone boots and runs normally after I ran fastboot -w. ADB commands work when the phone is booted normally. But is the 'bad block' message something I should be concerned about?
So 2 things - first, should I now be able to flash it with an official 2.1 ROM? I don't really want to reinstall Cyanogen as I had a lot of minor but REALLY annoying problems with it (bad touch and haptic feedback was the worst). I would just like to flash an official 2.1 for the time being while I find a better 2.2 port. And second, can you explain what's so special about this ROM that it worked when all the others I tried (at least 10 of them), including fastboot-enabled ones, didn't?
Thanks!

I have also two bad block but it seems that flash found them ,and skip writing to them so I think that is ok.

You should in theory: I found that I cannot flash my LG540 with any official ROM since I flash it with fastboot rom. ( and I wrote on several forums, no one give me answer) In fact, only few users tell they can flash it without any problem, but much more have same problem like me. So if you successfully flash with original ROM, tell me about that.
And second, can you explain what's so special about this ROM that it worked when all the others I tried (at least 10 of them), including fastboot-enabled ones, didn't?
I made it at home, in peace of my room
I dont know what is so special, but I rearrange few official ROM into fastboot for reason I tell before in this message.

Well thanks again I am in the middle of flashing official vodafone 2.1 so I'll let you know how that pans out.
Which ROM did you modify to come up with this one? It looks like baltic I guess
EDIT: Flash with official Vodafone Australia 2.1 ROM unsuccessful. The phone loops at the Android animation (although this is still further than I was getting before), I left it for a while (15 minutes or so) in case it was a slow first boot but it's still looping.
I guess I'll flash with your ROM and use that for a while, maybe I'll stick quarx on it.
thanks for your help mate I've been trying to unbrick this phone for nearly a week

So I tried to install black quarx using the guide in this thread: http://modmymobile.com/forums/527-lg-androids/557934-gt540-rom-black-system-rom-quarx.html
However the ROM that it says to install first leaves my phone hanging at the LG logo again. Something you did when you made your ROM avoids this problem that all other ROMs seem to cause..
I'm going to reflash with your ROM then skip the rom step in that guide and just install the black quarx system.img over the top of your ROM... we'll see if that works!

looking at the screencaps for that black quarx, something tells me I need the ROM as well as the system.img for it to work.... oh well we'll see what happens

That was case with me also. When I try quarx ROM I didnot have get it to work.
So I flash "my rom" then erase ALL
- fastboot -w
- fastboot erase system
- fastboot erase boot
and then reboot phone
fastboot reboot
Enter in fastboot mode, and flash it with quarkx ROM and should work without problem. But since black theme Quarx use i so dark for me I found it unusable, And ROM is not heavly modified so difference between them and stock ROM is not big. So for that reason I go back to "my" rom and stick to it...

I was modify UK ROM , BALTIC ROM, and OPEN EUROPE ROM ( you have it)
Baltic rom was smallest but have strange symbols when listing applications for remove ( white squares) . Also many other have that so I remove it from my phone. Beside that all was ok.
UK ROM was also ok, but have random FC on one application, so I finally flash it with OPEN EUROPE ROM, change application that have FC and now is all ok.
Battery have about 4 days of "life", phone doesn't slow down and I am happy with that ROM.
Yes, that is error I get ( but you go further then me, I stuck on LG logo)

Hey mate just noticed something tonight when I left the house (and got off wifi), mobile data doesn't work? I did a factory reset and it still doesn't work, double checked the settings and it should be fine...
Does it work on your phone?

Never have any problems with mobile data. Since you noticed wifi and mobile data doesnot work together.
Look at PAN for Internet, does at end stay: default- last option.
It must not be empty
Option name is APN model:

Hi, I'm stuck at the LG screen, can't enter recovery mode and have no idea what fastboot is. so I've downloaded V20B_00 from elsewhere and I'm unable to finish the process. Is there any different between that and the you FAST version? If so can you please let me know how I can get it?

Hi, I have the same problem, my phone was working fine until when I tried to upgrade to a higher version android and it fot stuck and took a long time so had to unplug it from the USB. Then when I tried to on it it was getting stuck at the white LG logo. Only once I was able to get it to the download mode, unfortunately I did not know what to do after that tried to plug it into my system but nothing happened, so just removed the battery after that and still standing at the same place. I teied as instrucked but nothing happenes. Please help me with this.

Bricked phone ?

Hi,
I tried to upgrade from v2.1 to new Android 2.3.5 Gingerbread For LG Optimus GT540 and I followed instructions exactly, but I am stuck at number 8, I did this:
8- Now click “Launch software update”, DO NOT USE THE PC TO THE PROCESS IS COMPLETE. THE PHONE WILL REBOOT WHEN FINISHED THE PROCESS IN KDZ. (The process takes about 15 minutes in KDZ).
and about 2 minutes text log writes and stopped, I am now waiting more then 40 minutes my phone didn't reboot. On display is still written download mode, what should I do now ?
In kdz is written:
3GQCT: wParam = 205. IParam = 36
p.s.
I disconnected phone from usb and pull out battery and now I cannot turn on phone, I tried to push vol down + power for 5 sec.
Any idea what should I do now? I hope I didn't brick my phone

What programs are you using?
What are you using to update your phone and have you tried taking out your SIM, SD card and battery then turned it on with the USB cable?

I used KDZ updater and tried to install CyanogenMod7 (2.3.5) @ GT540 Swiftdroid2 RC3 by Mur4ik. if that is what you ask ?
I removed sim card and battery also, then tried to turn it on while plugged in to computer usb but no response from phone, I can't turn it on
p.s. I am using win 7 64 bit OS

If you can't get into download mode, then it's game over I'm afraid. What you will need to do is return the phone back to where you bought it. This happened to me some time ago. But the Carphone Warehouse were happy to fix it (even though I had voided the warranty but don't tell them that ). Don't say that you tried to mod the phone, say something like 'I installed LG's PC Suite and it said my device had a software update. I went along with it, but it gave me an error half way through. Now my phone won't turn on at all' It might just work!

I had the same problem when modding with kdz.
completely bricked my phone, but was able to fix by putting kdz into emergency mode instead of diag and updating with a fastboot stock rom,
it would stop after 2 minutes and give me and error but it managed to get fastboot onto my phone,
(camera + power)
then just flashed the fastboot method with adb and everything was fine,
my problem was something to do with lg modem drivers i believe,
I read a thread that said to disable the lg virtual modem. (didnt
work for me)
pretty noob myself
but the above method worked for me,
not sure if this can do anymore damage to the phone

have a look at this is u get it into emegancy mode.
On the kdz updater instead of 3GQCT put into emergancy

If you have tried flashing with Cm7 you might be lucky,
try holding camera button and powering on the phone, a black screen should come up thats fastboot.
if that comes up u should be able to just reflash following mur4iks instruction
if not try what i said in my last post and reflsh with phone type 3QGCT and PhoneMode EMERGENCY
again only going of how i fixed my bricked phone

He was trying to flash a fastboot rom (to install CM7) but bricked his device in the process. So he can't flash CM7-.-

Yeah I know that but I mean when I got the error he has, I flashed with a stock 2.1 fastboot rom With Diag changed to EMERGENCY and was able to get on to fastboot mode (camera+power), I got the error again as i was flashing but the phone would load fastboot and not start up
If he can get lucky and get into fastboot like i did, a simple:
fastboot -w
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot
should fix his problem or did i just get lucky?
sorry if im confusing thinks here, but this is how i fixed mine. which was also dead and not turning on

Well like i told you im a noob at this myself (Android phone flashing atleast)
I suppose it would be good to see if you got fastboot??
Power on the phone while holding camera button (hold the camera button until the screen goes black) if you can get fastboot you can just follow the fastboot flash instructions after fastboot -w
if not on kdz in the top right were it says DIAG, Change this to CS_EMERGENCY,Click Launch update and flash again with a stock fastboot rom
after THIS see if the phone loads or boot loops(had this once too) or loads fastboot
Il try look to find the thread i read on another forum for troubleshooting kdz it helped me alot
EDIT: http://android.modaco.com/topic/321895-faqgt540-reference-thread/ try some of the troubleshooting tips at the bottom of the O.P
I basicly aimed to get fastboot working so make sure your flashing with a stock FASTBOOT! rom
again im new to this im just saying what got my phone back to life

I bricked my phone and I tried it again after getting it back from lg

I'm new here and to having a Smartphone, I've just been given an LG Android GT540 which is at version 1.6. The LG site tells me I can upgrade to 2 something or other, sorry can't remember the exact number and gives instructions on how to do the upgrade, but I'm a bit on the cautious side as I don't want to brick it, not this early on in owning my first Smartphone.
I'll be reading a lot of the posts here to try and find out as much as I can before I attempt to do this.

Well don't worry if it's official update. But if you some how brick your phone just tell lg the update bricked your phone and we are talking about unofficial updates

I've got phone today from service (not official LG service), repairman just manage to wake up phone so I can turn it On, but when I turn it I get black screen with message on it ''download mode''. Now computer recognize phone when I plug it, and I tried to update or flash it with kdz updater but have no luck
I launch kdz in emergency mode, load rom with updater, press launch button, and process started, (get messages unpacking software etc.) but after 3-4 minutes I notice that computer is blocked I couldn't do anything with mouse pointer, and I waited 15 minutes but computer is still blocked, even time on computer is stopped. I tried this procedure few times, every time it is same. Also tried to disable lg virtual modem in device manager. Any idea what I could do ?
p.s. repairman in service told me that he tried it to flash it with riff box, process started but after few minutes if stopped and blocked his riff box

[Q]Dead phone after flashing

So, my friend gave me his LG GT540 to flash it with a new ROM but I kinda messed it up.
I followed the instructions from here:
http://forum.xda-developers.com/showpost.php?p=12898827&postcount=3
After flashing 2.3.7. with 'fastboot installer' the phone won't turn on anymore! I'm holding the power button but I just feel a little vibration and nothing happens.
What should I do?

I somehow managed to put the phone in download mode but KDZ Upgrader always stucks on the same point while flashing (20:41:54 : Smart : wParam = 205, lParam = 215).
Anyone?

Do you have fastboot mode(blackscreen withback light) when you hold power and camera buttons on startup?

my friend had the same problem
he solved using fastboot on a pc with windows XP (he was on win7)

Got that problem, try differents KDZ, in cs_emergency and other computer!

No, I can only get in the download mode with VOL DOWN + POWER, but to acomplish that I need to plug my phone several times in and out of my PC and at some point it finally says 'download mode' on my phone.

used it to flash my brothers phone from 1.6 no probs

ok first what operative system you have. Second try to find another computer to do the process again if after all this doesn't work:
* i assume you have Windows, download Ccleaner if you already don't have it to clean your computer.
*If your machine has more USB slots try them.
*Disable Internet
*Disable antivirus-Firewall (some can give problem, puts restrictions. I use avira and first time it blocked the KDZ application i had to re-install deactivate Avira antivirus and firewall to be able to flash.
*If you are going to flash with KDZ now do it under CS_emergency
So basically you have to clean your computer , install from scratch even the phone drivers(Mines works fine in Windows7 x32 and x64 bits), try with other USB slot (better the ones in the back not front in desktop PC).
Report back
*Dont use fastboot installer do it the old way then
*Don't upgrade directly to 2.3 do it step by step 2.1 to 2.2 then 2.2 to 2.3

I was on WinXP 32-bit and now switched to my laptop with Win7 64-bit.
Now I have a problem with drivers. When plugging in, windows is trying to install drivers for 3 devices:
-LGE Android Platform Composite Device - SUCCESFULLY
- 2 unknown devices - just says 'installing drivers' but no succes
I have installed all drives that were in that .zip just like on the first PC but this isn't working here.
I tried to flash anyway with KDZ, but it says that 'phone was not found' and after that just 'finished'.

i flash mine with win7 64bit no probs for drivers i just keep trying to let it update from windows update and they work

OK, I somehow managed to get the KDZ starting the software update on my laptop but just like on my PC earlier it stucks on the exaxt same line:
14:08:46: Smart :wParam= 205; iParam = 215
After that I hear the 'USB-plugging-in/out'- sound while windows is starting again searching for some drivers.
Since this is the same problem just like on the other PC i suppose something is seriously messed up with the phone and I should just bring it to the repair center.

L5 bricked when KDZ got error

Please Help me somebody ... i cant afford to buy new phone i just bought this phone a week ago ..

Having same issue ! XDA forum experts always helped me with every situation with my phones. Expecting help this time as well from you experts.

Same here, enyone can help, i stuck with the sam message, presing vol- just rebots, and vol+ sends message "jump to download mode" but i cant flash stock firmware

i have the same problem any help ??

I have the same issue too, can anyone help?

I heard that this can help you guys. Use the search option there and try to fix it. Actually i had the same problem few months ago, but for me mew motherboard was the solution... If you're device is under warranty send it saying it failed while taking OTA. Good luck...

lg g2 critical error
I have done a flash to my g2 32gb d802 and it suddenly entered into critical error not going into any of thefastboot mode or download mode even though it is giving me options.....please any one help me out to get my phone back to normal ........

PM me if you guys need help.

I had the exactly same problem, and I had to go to afterservice center to repair. Engineer told he would wipe everything and install new rom. but He failed to write rom so he simply changed mainboard.
At first I had thought about open my g2 and makes it go into qualcomm download mode by short-circuit.
the reason I didn't was my warranty was still available.
I tried every method to make it boot into recovery or download mode but I failed. In my opinion, you may try short-circuit method for last solution. In this situation, even linux doesn't mount rom's storage section. Only if you can make G2 recognized in Linux, G2 will revive.
good luck.

The best way to go if you do not have a warranty is to short circuit the board and get into Qualcomm ... 9006 mode. However, when you get the demigod error plug in you usb and click up and it should start download mode even though it doesn't show it.

How do you short the pins? There's a guide here on xda but it's so difficult to undestand. I need to know how can I short the pins.
it should start download mode even though it doesn't show it.

No, it doesn't. I try to use flashtool but it doesn't recognize the phone. No download mode in any method I tried

I got into this error after I had previously recovered into qhs_usb9006_bulk mode from a hard bricked D801, by shorting the capacitors on the main board. After entering qhs_usb9006, I used srk tools 2.1 for my phone, and after they finished, I tried entering download mode, only to get into this error. I really don't know what it is to say about this. Everything turned wrong with this phone, it went from simply failing a .kdz, to stock .tot, to hard brick, and now to this error, whereas it should've just enter the download mode, as for the 99,99% of the others. Any help would be really appreciated. Thanks.
L.E. I shorted the capacitors again (the one i the middle, like I did the first time, when i got into 9006 mode. 5000 and 5004 didn't work for some reason). This time I got into dload mode, which is 9008. I'll try to recover the phone from here, with this method:

i had this problem while trying to return to stock. Fixed it by following this guide http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 . it needs some hardware tampering though. i tried and tried but i cant flash the phone any other way. the way i understand this is due to bootloader being corrupt.

I installed autorec from playstore solved all the problems

Than you! autorec worked for me too

Can someone post a KK baseband for D801 (T-Mobile)? I'm on D80120a software version with unknown IMEI and baseband (the phone is a D801 refurbished into D802, I more than hardbricked it by flashing wrong .kdz, got it recovered through shorting pins, 9008 mode, got download mode, D80120a stock, root, twrp, after a very long and painful process of about 1 month). Now I have to make use of QPST, but I have to obtain a valid baseband first. Of all links I've stumbled upon, only 5% or less of them are still working, so I only have one flashable modem, in twrp recovery, which corresponds to D801 jb version.
http://downloads.codefi.re/autoprime/LG/LG_G2/G2_modems
cloudyfa kk_baseband_D801 only make my phone restarts like crazy.
I'm simply stuck and pray for some devine help.
Thank you.

Weird enough, I flashed a canadian modem and I got both baseband and IMEI. Why did I do that in the first place? Because I remembered that before all these things happened to my phone, the baseband was M8974A-AAAANAZM-1.0.190082, which corresponds to D803. So I said to myself what can happen by flashing the wrong modem? Boot loop, easily fixable with the phone in it's current state. But again, after 1 month of trouble with the phone, I'm back to what exactly started it in the first place: phone seem to work OK but it has 2 huge problems: WiFi extremely weak (2 meters away and a wall or 5 meters away and no wall a and I lose the signal in both cases; the 2nd is wit the GPS - 20-30 meters error). No idea how should I adapt the radio to Europe region (by keeping the canadian one and change the settings, if it's even possible/fixable this way or if this even does make any sense).

I had to do a hard brick fix to get it into the QSUSB mode to flash TOT.

Have you tried using LG Support tool to put it back to stock?
