this phone lg optimus 3d (lg su760) just seems dead. it won't turn on, it won't go to recovery mode, i won't show battery charging status, i won't connect to laptop. laptop does make sound like its trying to connect with then phone. but after few attempts it just gave up.
i was in uk, but right now in Pakistan. i showed it to few mobile phone technicians and they said that its BOOT ROM DAMAGED. can anyone please tell me who can i connect this phone to laptop??? i don't know much about ROM, About KDZ or anything. but i think once my phone get connected with pc then i might be able to do something with it.
what do you thinks guys? will i be able to recover my phone or its just gone now..totally dead?? please reply.
At the moment you have no way to recover it by connecting to laptop,you need a new board.
Sorry, search doesn't work right now and i found this thread via google only. Hoping someone can pull magic out of their $$$.
I have an LG Optimus 3D P925G (but using the ThiaiZ ROM for a long time). Yesterday i was going to experiment with another ROM, so i copied some files from the SD to External SD via mass storage, rebooted into recovery and did a backup (CWM), and then forgot i wanted to copy a couple more files, just to be safe. So i rebooted into the phone, connected via mass storage, copied my files and turned the phone off. A bit later, i went to turn the phone on into recovery so that i can flash a new ROM and nothing happened. Phone won't turn on, no screen, nothing!
So here is what i tried, with two separate batteries.
1. Hold down 3D, volume down and power
2. 3d, volume up, power
3. volume down, power
4. volume up, power
5. home, volume up, power
6. home volume down, power
7. Took battery out, held the power button for more than 10 seconds, but the battery back and tried above options
8. All of the above while connected to PC via USB
-Some caused my PC to connect for half a second and go into continuous loops (you hear the PC trying to connect, but half the sound it usually makes, and then again and again...)
-So PC can't see it, ultimately
9. Tried above options with battery out and then putting battery in
I got nothing left to try...any ideas? Magic?
But i am guessing an expensive brick/paperweight is what i have.
Thanks!!!
Follow this step by step.
Install driver.
Use another cable.
Open Windows device manager.
Remove battery.
Insert battery.
Hold vol+.
Insert cable.
If it gets recognized it will show you LG communication port in device manager.
Release vol +.
If you cant see that and all you get is OMAP4430 you probably flashed wrong ROM and your LG can't be repaired with the tools that are available here.
Send from my Xperia Neo V using xda-developers app.
No go. Still get the OMAP, off and on in a continuous loop. The thing is, i didn't install a new ROM yet, i was planning on it but never got there.
Fun (sarcasm).

Pls help - same situation
Pls help! I'm in same situation. Did anyone manage to find a solution?
I am desperate because I need my phone all the time.
I have the same symptoms, and the OMAP device in device manager does the same thing. On/Off/On/Off...and so on..
If I simply plug my phone in, It just goes on/off/on/off ....... it only vibrates shortly when it starts and I can see the LG logo, then it turns off.
Did you enter "S/W update" mode ??(by insert battery while holding vol+)??

Search the threads ..
There are tools available that fix this problem
Wkpark fastboot tools make the phone almost unbrickable unless it's damaged the hardware
And it's very hard to damage the hardware

First things first. If you have tried all these, start afresh.
uninstall all LG related software, reboot laptop and start again.
search the forums for all related issues, read read read, understand and follow the steps exactly.
you will have your su760 up and running!!

Hi guys, i just wanted to unlock my phone's bootloader when my computer was suddenly getting 'blue death'. My phone turned off, I tried to turn it on but nothing happened. After that I found some fixing method like SEUS, Flashtool (installed drivers to recognize my phone..), but im still bricked 'cos none of these programs can recognize my phone. When programs say 'turn off phone - hold back key - plug in usb' i get nothing, i mean i know what is flash mode (with the green led) but i cant get into it. I've tried all buttons on the phone (even combos like - power button & back) but noting. When i plug in the charger the led isnt light. Please help me i want my phone back. - and sorry for my english
Same problem: Hard bricked x10 mini pro
I have exactly the same problem as you.
I have had no success in finding a solution, because the phone cannot enter flash mode. There are absolutely no signs of life in the phone even though bootloader unlock was reported as successful.
Any ideas guys? Or can you recommend a decent, trustworthy repairer?
Cheers
the only one here with any inkling of a solution
if i am not mistaken, the only way to solve this problem is to J-tag your phone.
basically, what that means is you take your phone to a repair shop, they take apart your phone and plug in a chip which enables certain debugging features, and they simply re-flash your phone for you.
however, unless you are willing to buy a J-tag board yourself, you need to pay 20+$CAD for this.
After all, they need to make money too..
My phone is dead after switching external sd with internal sd via CWM script .zip file and a little tinkering in the phones system files.
(“I have done this before with success but had just flashed new firmware, and in the rush I was in wile doing it I obviously did something majorly wrong and super bricked my phone”)
After rebooting to complete a step I was doing, the phone did not turn back on, the pc does not detect it properly anymore, no button combinations work, such as pressing vol up when connected without battery, power button and pressing up + vol. No RESPONSE:.
when plugged into the pc it just flashes "OMAP4430 device" but appears and disappears all the time in device manager, now I know all drivers are correct and how to go into download mode, recovery mode and every trick you can with the O3D but none work anymore, phone does not turn on and it only recognizes it for a second showing “OMAP4430 device”.
PS Sorry for the new thread but I have searched the forum and the internet with no real answers, it would be great if there’s a fix for this situation or is my O3D dead to the world never again to be reborn.
NOW IF ANY ONE HAS MANAGED TO FIX A TRULY BRICKE O3D LIKE MINE PLEASE HELP!!!!!!!
sounds like a harware brick i did that to my thrill had to take it in
That’s what I’ve been fearing, my other issue is that the phone is actually a LG thrill from at&t I just call it a O3D because in Australia were I live we only have O3D, and let’s face it they are basically identical, any way would that mean I would have to send it back to the USA for repair?
well is it under warenty? if so youll have to send it to who ever you bought it from. if it isent ull have to get a new logic board and relace it your self or have some one relace it. or send it to lg to fix it
I had a similar problem when installing rom. KDZ:
http://forum.xda-developers.com/showthread.php?t=1473781
http://forum.xda-developers.com/showthread.php?t=1244490
The problem with "OMAP4430" device I solved by connecting the phone to the computer via a cable from HTC Wildfire (such problems I had with the original cable, LG).
It can change the cable will solve the problem.
I wish you luck.

You have to remove the battery when omap flashes on device manager let go off the button and push and hold it agen it should stay. try this time omap like have your cursor ontop of omap4430 as soon as it appear quickly right click properties and find the driver unplug reconnect it will install the driver when it detects it agen i think with this phones its impossible to hardware brick the phones if only it was easy like samsung just plug in download mode let drivers install and push start button done. if flashing a phone was like a movie lg would be inception
trust me i totaly bricked my phone i tryed every trick pulling the battery out and putting it in in download mode problem was omap didnt even show up just the other one and it would flash on and off way to fast to click on it in device manager then it would just stop.
So did you end up taking it in?, it should still be under manufacture warranty well hopefully I got it in october and I don’t even think the O3D has been out for a year yet.

The problem is that it only starts flashing with the battery removed so, and I can’t get into download mode at all, which is when it normally stays there and detects it properly, otherwise the drivers are all installed.
If it flashes omap its not a complete brick. If all fails try the resistor cable. You can find a post around in the forum
I have tried the resistor cable using 910k resistor, and I even checked it on the multimeter and it reads 908k resistance which should be ok since I think you can allow for a 1% difference.
I could figure out that ur device can be detected as OMAP, this means it isn't bricked totally, please be sure U remove UR battery, connect ur USB--phone side, then press volume up and insert the USB--pc side while pressing the button and continue pressing while ur pc is installing, first it will show OMAP, then after 10-20 sec it will show COM added, don't stop pressing until it finds the COM and installs it, then directly stop pressing and insert battery and don't try to turn it on and start flashing as usual
try to use other USB cable model like sony ericsson, it never failed me
hoping U will be lucky
See the problem is that no button combination work on the phone, pressing a button is like talking to a wall you get no response lol.
I have the same issue and I bought my phone off of Craigslist.. is there anything I can do? I cannot send in via warranty because I do not know when the phone was bought.

its hardware bricked need a new logic board sorry to say
Hi, i had the same problem while upgrading to gingerbread. What windows version are you running? Ihad the same problem using win 7 x64. Got to a win xp computer with no lg software installed and used the tutorial of unbrick from this forum. had to try several times, but at least step by step my phone got back to life. Main thing is to get omap drivers installed on XP with no battery. Then taking the other steps mentionened under unbricking your phone in this forum.
Hope it helps
I have the exact same problem and NOTHING works.
Just to clarify everything, you guys had the same problem where the OMAP4430 device appears and disappears over and over again in device manager and by doing what you all describe, the phone got brought back to life?
Because none of those things work for me, I even tore an old sonyericsson phone apart to get the phone pins connected to my O3D battery and see if the old phone turned on, which it did, so the battery does work.
I installed the OMAP4430 driver without any problems and I guess from here, everything seems to be working for you other guys, right? Because the OMAP4430 is still getting connected and disconnected 10000 times BUT as a "Known" device which has the driver installed.
No need to answer this with "you need to send the phone to LG". Just want to see if I'm on the same track as the guys who got their phone working.
Btw, mine got bricked when formatting the external SD card with CM. Seems as if CM formatted something else..

So let me get this straight. Like a few months ago, there was a way to completely destroy your phone:
install CWM and run an OTA update on stock rom.
That completely ruined my phone. It was explicitly said that no unbrick method is available.
Now I hear several people reporting yet another unfixable brick, caused by
- Erasing your SD card through cyanogenmod
- Formatting /data ?
All the available methods of unbricking are said not to work. And by those methods I mean
- Opening recovery and do a factory reset (recovery can't be opened I heard?)
- Connecting to a Windows 7 PC with battery out and volUp depressed (device disappearing reappearing)
- Connecting to a Windows XP computer With battery out, volup depressed (Same problem as Windows 7?)
So to put it simple:
Doing some things with CWM OR CyanogenMod can render your phone unfixably bricked. There is a genuine risk in hard bricking your phone when you have CWM and/or Cyanogenmod installed.
I'm not going to install either of those for that very reason.
If the omap 4430 is detected when connecting the phone, then the phone should be recoverable. Try another pc system and then use the official lg recovery tool entering the imei number which should hopefully restore the stock rom.
Can i clarify whether or not any other devices appear in the device manager (Remember to hold the up button without battery until these appear and then insert battery after
The entries in device manager that should also appear would be something such as the following (This would probably vary based on whether in normal connection mode or flash mode)
PORTS
LGE android platrom usb serial Port (Com x) x may vary on system
UNIVERSAL SERIAL BUS CONTROLLERS
LGE Android Platform Composite Usb device

They said that the omap driver keeps appearing and disappearing. You can't do anything if a driver does that!

Hello, I know, this question rather belongs to this thread:
http://forum.xda-developers.com/showthread.php?t=935578
but since I had no intention to flash my phone and I also have not enough posts to reply to the other thread, I hope this forum might be the right one
(edit: sorry, somehow I managed to get even this wrong. I wanted to post in the LG Optimus 7 subforum )
I installed the most recent update, when my LG lost connection. I then removed the battery (duh!) and eventually it transformed to a pocket warmer (well, it got no other function than heating up ).
I tried all the things Microsoft recommended me (Phone recovery tool on different computers & different usb slots ).
But always the same message : Can't repair, contact service.
So I stumbled upon the flash thread. I managed to get my old winxp sp3 rolling and installed everything. After countless tries my phone was recognized and it was even successfully flashed - wait!
It shows 100% and then the emergency download screen disappears, it reboots and shows up the LG logo.
The same state as before. (I am also not able to shut it down, it keeps firing up itself)
I tried the format all keys (vol + - & pwr) but it doesn't accept this combination.
I tried the vol - key in emergency download, but it does nothing
So i downloaded the European firmware besides the German one (allthough the download I could find, only had ~170 MB)
Anyways, it had no effect. Still only the LG logo, nothing more, nothing less.
Zune only shows, I should contact service (like the support tool) and the phone itself only accepts the key combinations for connection mode, cold boot, emergency download + power off (although this is rather a reset function, 'cause it always restarts)
Is there anything I could try which might get Windows back on my LG (besides sending it back to manufacturer ) ?
Thank you in advance and sorry for any spelling / grammar mistakes I made
Hi friend,
you can take out the SUB board (the board which insert SIM card), then Power ON. If you can get in to Wellcome Screen. You can fix this problem.
==> The eMMC Toshiba IC got problem, try to re-solid it. i was do this way and my fone working again.
sorry about my English.
Hello. So i recently have this error with my at&t Lg g2. I have been researching and have found so many threads and dicussions via Google. I am so confused. I literally am dumb i guess according to all of these solutions and believe it or not im pretty savy at least so i thought until this. So my phone is stating Critical Error. It states the message press volume + for download mode, connect usb. etc.. then it states press volume - for reboot. Ive tried both. It's also stated get the ram dump image using QSPT Config. I've connected my phone to the usb and pressed the button volume + and it states dload mode pressed or jump to download mode. But it does nothing. Am i suppose to do something on my PC? when it states jump to download mode?
Now when i look at my devices connected it classifies my Lg G2 Under a category, (folder) "unspecified" and it shows a device icon with a yield symbol and states Unknown USB device.
Please help. As u know a cell phone is urgent and at this time with my health i desperately need a phone. Please help. I will stay on watching for a reply. Thanks and God Bless.
Hi
I've been browsing the forum to find some help, but nothing matches exactly my situation and it is stumping me.
Have one plus 7 pro GM1913, attempted to install the latest update today that was pushed to my phone a few days back and set the phone down with charger cable attached and then look back at it and the screen is back at the security code entry tap my code and then back to booting, then black screen.
Attempted all manner of the key combos to get into the different reboot, fastboot modes, occasionally would get back to the loading screen which would then freeze with occasionally distorted graphics (one plus logo).
And now after a bit of charging (phone doesnt indicate it is charging at all) can't even get it back to the crashdump screen I could get to.
Crashdump screen didnt indicate any errors.
So i've been looking into possibly trying to trying to unbrick it with msmdownload tool. I have managed to install the qualcomm drivers, i believe i have the right version of the msmdownload tool.
However when i try attach my phone to the pc it keeps disconnecting all the time, my running theory is the phone is on and running through the boot sequence but I can't see it, but each time it disconnects then reconnects etc. Anyway I can't maintain a connection long enough to attempt msmdownload tool.
I also can't seem to boot my phone into EDL mode, following the below instructions:
Power off the phone.
Plug in the USB cable your computer but do not connect the other end to the phone.
Hold down Volume Up and Volume Down buttons for a few seconds, and plug in the cable while you are continuing to hold them.
You should see the anticipated EDL mode.
I am a complete beginner at this, but considered myself relatively tech savy enough to give things a go, but there is the old adage about knowing enough to be dangerous! Any help is appreciated.

I actually start the MSM tool ,wait until it boots up, position my cursor close to the start button on the tool, then I connect my phone to cable make sure it's attached to both PC and phone , put phone in edl ( hold power button and both vol up and vol down at same time) phone should go blank and you should see a connect on the MSM tool, hit start,,,, hth
My phone appears completely blank anyway, i've left it off charge overnight and then attempted to charge this morning, no real change. I've got no indication if the phone is charging or not or if it is even on.
When I connect via usb to my pc it is connecting and disconnecting constantly. I can't see anything via the screen.
What should edl mode on the phone look like?
Prior to this update there were never any issues with the phone, so im pretty sure it is connected to the update, just dont know how it has even wrecked the bootmodes etc
