[Q] Phone not detected by Computer, or KDZ Updater - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hi!
I have developed a problem with my LG Swift L5 (e610) phone. The problem is, that I tried to downgrade from Android 4.1.2 to 4.0.1, but I must have chosen the wrong KDZ file, because the phone is bricked, all I see after turning on my phone is a white screen (But I think that it is working, because I can hear the boot sound, and the screen dims). I have included a photo of my phone below.
Now here comes the real problem. I have got all the drivers installed, but my phone isn`t detected by my computer. And I don`t think my phone detects my computer either, because when I connect my phone to a USB port, the screen doesn`t light up. When I connect my phone, and try to flash a new system using the KDZ Updater, my phone isn`t detected either.
I hope somebody out there will be able to find a solution to my problem! Thanks.

can you get your phone to download mode?

Hi, thanks for your reply!
Well, I don`t actually know if my phone is in download mode (after using vol-up + vol-down + power), because the screen is white! Let`s put that as a no, I can`t boot into download mode. Does anybody have any other ideas?

1. Switch off the phone
2. Remove battery
3. Hold power and volume up button
4.Plug in USB cable
....and phone will enter into emergency mode.
Drivers for USB my install, let them finish and then flash the KDZ you want using KDZ updater.

Hi, thanks for your reply!
I did exactly what you told me to do, I even reinstalled the LG United Mobile Driver, it seems to detect my phone now, but I have came across a new problem. Here is the log:

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
Click to expand...
Click to collapse
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.
- first, should I now be able to flash it with an official 2.1 ROM?
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?

I teied as instrucked but nothing happenes. Please help me with this.

[Q]Any way to unbrick my phone?

I have installed swift droid on my GT540 and tommorow i wanted to change the the system to 4.0 by Mike Gapinski. Before flashing mike gapinski's rom i tried to install the original android and id failed. Now after LG logo there's a linux kernel panic
Process init (pid: 1). I've tried flashing with kdz updater on EMERGENCY and CS_EMERGENCY with that V20_a French rom but the log got stuck at wParam=205 lParam=215 and after it the phones reboot and kdz doesnt do anything more.
Please help me!

are u able to enter recovery / fastboot mode?
Download mode only
Use kdz updater to flash a 2.1 rom that has fastboot enabled. Use cs_emergency mode (phone in download mode).
When it finishes (or just stops) pull the battery then put it back in and go straight to fastboot.
Connect to pc and do:
fastboot erase boot
fastboot erase system
fastboot erase cache
Then flash recovery back on. Then use recovery or fastboot to flash whatever rom you want...

Hi my friend, i've experimented this problems months ago, when i started with my phone..
This is the only solution i found, risking:
Follow the same process, and when the log got stuck at wParam=205 lParam=215, disconnect the phone, wait 2 seconds, and reconnect in download mode, the process in kdz will continue until the end..
We hope your results
When i bricked my phone too the process in KDZ used to freeze at the same point as yours...just be a little more patient and the process will proceed and everything will be ok..KDZ is a very useful tool at times like it..
Stuck
After flashing to European ROM-fastboot its stuck at android logo. Any other roms causes nothing to happen.
Help
Anyone knows what to do? I dont have warranty.
One of my friend had the same problem (stuck at android logo), I don't remember exactly how we fixed it, but we fixed it by trying everything written on XDA.
IIRC we tried a lot of ROMs in normal and both emergency. Don't forget to close programs that could interfere with the flashing process (anti-virus and such)
My post isn't useful but it's to let you know that there's still a way to fix it.
Does he remember what was the topic?

After flashing European rom from kdz, you must enter in fastboot mode and flash whatever personalized rom you want.. swiftdroid asis, utopia, ics beta 4..
To enter in fastboot mode turn off your phone and then press camera button + power..
Thanks
Thanks ! It worked !
Thank you all!

I have goofed up big time in trying to roll back Android 2.3.7 Gingerbread (Swiftdroid) CM 7.1 to stock. I used KDZ updater and got up to "Smart : wParam = 205, lParam = 215". Then the it stops and the phone tries to reboot and is no longer recognized by windows vista. The phone scree shows:

There are multiple lines after that which fill rest of the screen. I guess I can take a photo and post it if required.
I followed the above advice, put the phone in Download mode and left KDZ to finish. then I got this log:

OK. I used KDZ to flash romfastboot, then reinstalled Android 2.3.7 Gingerbread (Swiftdroid) CM 7.1 and all is well again.
Maybe (just maybe) you're flashing a wrong image...GT540 is ARM6 based not ARM11 as the message says.

I am having this exact same problem, but the solution wasn't clearly written in this thread....
Whichever rom I try and flash using KDZ, they all get stuck at the android boot logo when trying to turn the phone on.
But so what exactly is the solution please??
Mate it's a 3 year old thread, but I might just have the solution somewhere just give me til tomorrow.

Cheers thankyou.
This has literally ruined my entire life currently, as having my phone broken has made me lose so much stuff in my job and everything.
Ive looked all over this forum and others but everyone just keeps saying the same rubbish about ''flashing using kdz'',
but that simply doesn't work, and the kdz tool is just a piece of crap in my view!!
But so if you know the actual solution il appreciate it so much
What KDZ images did you try to flash? (BTW KDZ is the only way out of this situation). What exactly does your screen say while booting?
In my case, from what I remember, I either tried flashing one of the multiple images published in this forum and it just clicked, or i may have tried unplugging the phone while flashing with KDZ just to see if breaking it further may undo the damage done before, but that is the last resolve.
When you post additional info and whether you want/can try some possibly bricking techniques I can help you more.
Till then mate.

I managed to unbrick it yesterday.
I used KDZ, cs-emergency, it was saying phone not found but using a trick from a page on facebook I removed the battery and reconnected the usb (it showed a screen saying it needed battery), but KDZ detected phone and it flashed 2.1 (update 1) which I think was a stock rom.
I then managed to get it back to 4.2.1 rom by using fastboot to flash 2.3.3 rom,
then using fastboot again to flash 2.3.7 rom,
and then using recovery to install 4.2.1 rom from zip.
Im still having the exact same problem with the phone as before though,
as when I try and use Mounts2sd, the phone just screwsup totally.
Its because it always says ''error mounting sd-ext''.
I cannot use the phone without mounts2sd though, since there isn't enough memory for even 1 app without it! :'(
But re-partitioning sd cards just destroys them.
I had to go and buy yet another sd card today as the other 2 had been ruined totally by the phone!!
I tried to re-flash the 2.1 rom via fastboot and also tried through recovery.
When trying through fastboot and KDZ the phone wont get detected by KDZ (removing the battery now doesn't make any difference like it did yesterday as it wont do that same screen it did yesterday),
and when I tried to flash a 2.1 rom I found via recovery it just showed a screen saying loads of errors and that my rom couldn't allow that, and then the phone wouldn't turn on just kept getting stuck at the cyanogen logo.
So I had to go and buy a brand new sd card, put it into my computer, put the 4.2.1 rom onto it, start phone in recovery which it could still get to luckily, and then install that rom again.
But so now I have a phone that is on 4.2.1 rom, will turn on ok, but cos there is an issue with the SD-ext mounting,
I cannot install mounts2sd, and so cannot use the phone!! :'( :'(

LG L7 P700 - P705. Please Help Me. L7 Wont turn on!

I have LG P705 and have P700 v10i firmware.
And I have rooted, unlock bootloader and also instaled cm10
recently it working fine and I just wanna restart My phone and then I choose to reboot My phone.
After the screen light turn off, it wont showing up again.
I try to push power button a couple times but nothing happen. Even with CMW power buttons.
I try to put in rechargeable usb, wish that will an battry icon show up. But NOTHING.
Is it dead? Is there a way to revive?
Please..help Me..
===========================================================================
I'm sorry for late Update.
In My Case, the phone is DEAD, problem is on the hardware.
BRING TO LG SERVICE CENTER AND YOU WILL STILL HAVE THE GUARANTEE. JUST DONT TALK TOO MUCH LIKE SHOWING UP YOU KNEW EVERYTHING!! JUST BRING AND TELL GOOD REASONS WHY ITS DEAD!
IF YOU DONT HAVE THE GUARANTEE, BETTER GET A NEW PHONE. THE HARDWARE REPLACEMENT IS MORE THAN $80 FOR ASIA PASIFIC.
Some master who have first LG L7 will know this handset still have some issues with the hardware, especially for LG in Asia Pasific.
i have the same problem? any solution

Well, your phone is hardbricked. The only solution is send phone to service. I hardbricked my phone 2 times and only solution was repair bootloader via RIFF JTAG.
@gefademe2d @dami7bl
Ok firstly just relax..i dont think that it is hardbricked
Pull off your battery and find a cable to connect your phone to your PC..connect it while pressing volume+ button(without battery,only usb cable)..
If that works it will boot on emergency mode(yellow screen)..open kdz and flash again...
Be sure to have lg's drivers installed and run kdz as adminstrator :sly:
Hit thanks if i helped

Hard reset steps L7 P700/P705
Old post, but if someone ever have this problem.. here's what I did. It happen to me not long ago, I tried everything I tough could help but nuting worked. So I decided to go for the hard reset. I was on V20E with root + bootloader + cwm recovery and did the manipulation for a hard reset. You have to know that it will delete the data from the phone memory.
Steps:
1) In Power Off condition, Press & Hold "Volume Down key" & "Power key" together with your left hand
2) When the LED at the bottom of the phone lights up, touch & hold the "menu" key with your right hand
Menu key should be pressed immediately before the screen displays the LG logo)
Make sure that your left hand is still holding the "Vol Down" & "power"
3) Release the Power key when phone vibrates.
4) When LG logo is displayed, then continue to hold other keys for about two seconds & then release all keys at the same time, before the LG logo dispapeares.
5) Leave the phone for a minute to allow the hard reset to take place. After that phone will reboot.
I don't know how, but I had CWM recovery and doing this, it took me directly to the recovery mode. Then I was able to wipe data/cache and flash a proper ROM again.

Then try launch software with type 3GQCT and phone mode CS emergency. Next, connect phone via cable usb without battery. Maybe reinstall kdz and drivers.

If you currently have a Jelly Bean then install Jelly Bean.
Uninstall KDZ Flash Tool + drivers and install again.
1.Install drivers.
2.Install KDZ Flash Tool.
3.Turn off your phone. Connect phone via cable USB and pressing volume + and power (without battery). On screen shows emergency mode with yellow background.
4.Open KDZ and:
a) 3GQCT + EMERGENCY
b) 3GQCT + CS EMERGENCY
Disaster recovery software for LGMobile Support Tool rather not work. But you can check it.
If you have P705 then install for P705:

Are you sure you set TYPE to 3GQCT and Phonemode to DIAG and are you sure you have the right ROM and also make sure you installed msxml file.
Also try taking out battery and checking if any of the volume buttons are stuck

i need to see the log
but for now take out your battery, and plug your phone into your computer via USB while holding volume up.
now go to KDZ updater
set it to 3GQCT and the next option to EMERGENCY
select your KDZ file
then click launch software update.
if it gives you errors dont worry just wait for it to finish. (if the program freezes dont worry just wait it out)
thats it just wait for you phone to reboot on its own and you should be good
