[LG Optimus 3D] d347hxd:
I'm going to be straight out and say that I know next to nothing about this side of phones (repair, flashing, etc). So please be patient with me if I don't quite understand stuff that seems simple.

I own a LG Optimus 3D (LG-P925g)

I had JellyBam, but noticed it ate my battery life like nothing else so I flashed Promethius Kernel V1.5 thinking it would replace the ROM. (Now I know ROMs and Kernels are completely different) Ever since that, when I start up my phone it goes past the LG boot screen straight to a white screen that has a bit of random pixels everywhere, as I said in the thread I came from.

I tried your tutorial but there are a few parts I don't quite understand and are having problems. For instance in the beginning of step 2, you say to take out the battery... and the same goes for step 4, but no where in between does it say to put the battery back in... when do I put it back in? I did install the drivers correctly though.

When I launch the fastboot stuff, and do all that I get through well (do I put the battery back in when it says waiting for 5 seconds?), and it asks me all these yes/no questions. http://i.imgur.com/3wtWv72.png being the first, as the person in the previous thread said; I will type N for the fastboot devices thing. Next question comes up, http://i.imgur.com/hHc5vUL.png... the guy said to say y to this, so I do it... then it gets stuck right here: http://i.imgur.com/VC1OpCI.png. Please note, I did not insert my battery at all from plugging the cable into the phone while pushing the vol+ button, I let go of the vol+ button once it started asking me these questions.
[LG Optimus 3D] Karim Kahale:
First, are you using the same version of omap4boot included in the thread ?

Ok and you are right, no removing battery or inserting it again between steps 2 and 4.

I want you to check something : it's checking if your device is half-bricked.

To do that, I want you to skip that and start from step 17 and see if your phone can boot in BLACK DOWNLOAD MODE.

Any more help is welcome :highfive:
[LG Optimus 3D] d347hxd:
Okay, at this point I do think it is 'half bricked' I am not sure how to use SmartFlashTool exactly, but this is what I did and what happened:

Launched SmartFlashTool: http://i.imgur.com/TIT14nD.png

Clicked the 'Add' button: http://i.imgur.com/RM75iRp.png

Selected BOOTV21E_AP.bin: http://i.imgur.com/ow8Lysu.png

Took battery out of phone

Held Vol+ button

Plugged Phone In

Waited a few seconds, then this is what the menu looked like: http://i.imgur.com/PknI5G0.png

Clicked start, and instantly played a part of this french song that scared the **** out of me and I couldn't understand because it was only like 1 and a half words said, and as it did the song this popped up: http://i.imgur.com/YvLuaYU.png

Pushed the X in the corner, as there was no "continue" or "exit" buttons.

Came back to this (not detected under Communication setup) http://i.imgur.com/ctxCM0G.png
[LG Optimus 3D] Karim Kahale:
You are about to unbrick your device ! Just choose ROM COPY TAB instead and add CP and AP files and flash while holding vol-up button !:laugh:
[LG Optimus 3D] d347hxd:
http://i.imgur.com/cxTfB4L.png
[LG Optimus 3D] Karim Kahale:
Did you open windowsenabler before ?

If yes, try to press the 3D button instead during the flashing process .
[LG Optimus 3D] d347hxd:
I did not start that, but I did and then this is now happening: http://i.imgur.com/HGrdJ7X.png

What do you mean hold the 3D button instead? Meaning instead of pushing the vol+ then plugging it in, instead the 3d button and plug it in?
[LG Optimus 3D] Karim Kahale:
Plug the usb cable in while holding vol-up and during the flashing process keep on holding 3D button .
[LG Optimus 3D] d347hxd:
So when it is flashing, I need to be holding both the vol+ and 3D button?
[LG Optimus 3D] Karim Kahale:
No, it's either vol-up or 3d button
[LG Optimus 3D] d347hxd:
Yup, still doesn't work.

EDIT: We brought this conversation into a private chat, and we got it working! My phone is unbricked!

Thank you so much! :D

First of all congrats for your hard work. I followed the steps 1 to 15. I flashed the ICS bootloaders (I couldnt flash GB bootloaders) and CWM recovery. But I still cant flash into recovery. I pressed first vol-down and 3d button then power button, and it still boots in Safe Mode and not in recovery!! Any kind of help please?
[LG Optimus 3D] Karim Kahale:
The good thing is that you can be sure now that you can resurrect your phone.

After flashing the ROM, you can be sure that this problem would disappear.

PROCEED WITH THE NEXT STEPS ! :laugh:

I want to flash the OptimusRS Xperia ROM ICS V6, but it is a zip file, and the smartflash tool only allow bin files! What should i do?
[LG Optimus 3D] Karim Kahale:
Download the ROM included in this thread which will fix everything, then flash cwm and install the zip file :highfive:
[LG Optimus 3D] sokpip:
I only flashed the ICS bootloaders I am in ICS V30A and I couldnt flash GB. Isnt this ROM included, a GB ROM? I want to stay in the ICS! Do you suggest to flash this GB ROM, so I can get in the cwm recovery, so through recovery to flash another ROM?

Lg drivers

Hi. I think I have serious problems.. When I attempt to install LG DRIVERS, it fails..
[LG Optimus 3D] Karim Kahale:
So you're having this Window when you are connecting your phone ? Or this is happening when you are installing LG drivers in the first step ?

Did you disable automatic updates and driver updates ?

Is there any antivirus running ?

[LG Optimus 3D] Karim Kahale:
Let's see if your device is half bricked.

Skip to step 14 and continue from there. If your device gets recognized in Ports, you can proceed with the flashing part.
[LG Optimus 3D] keycam:
I don't know if it was intended or what, but i believe my phone fixed itself. When i flashed everything in blackscreen DL mode, CWM showed on (bugged, i couldn't do anything else than clicking "reboot") and eventually my lovely LG started working again.

Thanks alot man, i owe you ;)
[LG Optimus 3D] Karim Kahale:
Good Job !

Actually CWM boots everytime after the flashing process, so you could've flash any ROM you wanted.
[LG Optimus 3D] nikosar:
Help, i'm stuck at 14 step. The os_hacking tool does not flash GB bootloader, it pops up a message in the end about "waiting for device". Can anynone help?
[LG Optimus 3D] Karim Kahale:
Are you sure your device gets recognized as Omap ? If yes check that also with omap4boot tool.

If nothing works, skip the OS_HACKING step and see if it works for you because sometimes half bricked Lg phones can be fixed without this step

but it depends.
[LG Optimus 3D] nikosar:
Anyway i moved on, but now i stuck at step 18 with the diconnection problem. No matter how many time i connect it, i disconnects in less than a minute. Is there any solution for this?
[LG Optimus 3D] Karim Kahale:
Are you sure you are holding volume up all the tim?.Sometimes you got to press 3d button instead.

Can you post a screenshot of the error you are experiencing ?
[LG Optimus 3D] nikosar:
Error in step diconnection problem. I press vol button all the and the 3d button....
[LG Optimus 3D] Karim Kahale:
Did you enable windowsenabler before ?

If yes try to restart your machine and try it again with either pressing vol up button or 3D button
[LG Optimus 3D] nikosar:
i have enabled windowsenabler but not restarted the pc. Let's try this and hope......
[LG Optimus 3D] keycam:
Oh, didn't know that, i had to manually flash it in my previous phone. However, there's one more thing that disturbs me - as i said CWM is not working as intended (resets after clicking anything apart from power button), therefore i can't stick to my original plan of installing CM10 from .zip...

Is there any other possibility to do this? Or will i have to flash CWM again, this time on working Optimus?
[LG Optimus 3D] Karim Kahale:
It would be much better to flash recovery again to ensure everything is working properly ;)
[LG Optimus 3D] OmerKH:
Thank you my friend you are saved my life

I can flashed by smart flash tool. But my installed GB is not started. Ringing starting sound after LG logo loading. But that process is never stopped after 1 2 3 4 30 minutes.

If I install other ROM files, my problem will end?

But I haven't other ROM

Sorry for my bad English.

Help me guys!
[LG Optimus 3D] Karim Kahale:
What you got to do is flash gb bootloaders again and flash cwm recovery. You can then flash a ROM via CWM recovery or stick to bootv21e if it boots.
[LG Optimus 3D] Galaacule:
Thank you

I am trying...

---------- Post added at 01:21 PM ---------- Previous post was at 12:34 PM ----------

My phone is working normal like new. But my sim card is not connected. I did try another sim. But not connecting Service status is NO SERVICE.

What should I do? :confused:
[LG Optimus 3D] Galaacule:
Thank you.

But question is:

Should I flashing the CP? I want to skip this step and I only restore IMEI? If I do it my sim loading and my IMEI restore?

Beacause don't understand how to flash KDZ file.
[LG Optimus 3D] Karim Kahale:
Didn't flash bootv21e at the beginning? You should be doing that because it usually fixes all IMEI problems.
[LG Optimus 3D] laloquisloli:
Well... I read the topic but for me it's not working. I'm not able to see the silver LG logo.

I'm able to see the port in devices as LG, but when I tried to use the smartflash tool in the middle process got stuck (throws an error).

There is another posibility for me?
[LG Optimus 3D] Karim Kahale:
First, did you open windows enabler ? Are you sure you are holding the vol up button during all the flashing process? Did you try the 3D button instead ?

Please upload an imaage of the error you are talking about.
[LG Optimus 3D] laloquisloli:
I was following all the steps. Here the screenshot:
[LG Optimus 3D] Karim Kahale:
Are you sure you changed the com to com41? I see com6 in the photo
[LG Optimus 3D] laloquisloli:
You are right, the main problem for me it's change LG USB Serial Port to com41. Is not happening :rolleyes:
[LG Optimus 3D] Karim Kahale:
You must change it manually from device manager, did you do that ?
[LG Optimus 3D] laloquisloli:
How do you change the port manually?

---------- Post added at 08:48 PM ---------- Previous post was at 08:28 PM ----------

I hope you are thinking to change the port in a strange and difficult way... But If you mean only select the other port in combo box, I'm not able to do it as I wrote... No matter the program that runs.

Never appear the com41.
[LG Optimus 3D] Karim Kahale:
Open device manager, select the LG port and open its properties by a right-click. Go to port settings tab, then click on advanced button. When you see a drop down menu, click on it and change the port number to com41.

Thank you so much for your help.

Now my problem it's the SIM card, I don't have coverage. Also I've check the IMEI number using *#06# to get it but nothing appeared... Could be related?... how can I fix it?

I found this:

Restoring IMEI

1. Connect phone by USB

2. Activate USB debug mode

3. Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#

4. Select Port Settings -> Select CP Image Download

5. A new device should appear at let it install

6. Open Tutty and select serial protocol. Click on open

7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)

8. Type at%imei, it should display your current IMEI

9. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number

10. Reset

The process was fine but when I restart, my IMEI still empty.

To access CWM recovery, hold vol-down, 3D button and power button.

After success flash of P990, Disaster brick with P920!

Hi Karim, nice work you have done!

The reason of my message: After rooting Xperia Neo V, and Xperia Pro, moving them to CM10.1, I decided to do the same with my P990. I did but it was really bad, so I found how to move the official V30A from LG.

But then I was so happy with my results, that I offered a friend to flash his rooted P920 (that was working really bad) to the official V30A ICS for his P920 as well. So I downloaded the right (I think) FLS/BIN files, launched Windows enabler and started the SmartFlash tool...

I got stuck here:

The red Error message appeared on screen with a noise. I tried another time thinking my USB cable had disconnected or something, I got to the exact same point again!

So I found the following solution to unbrick the P920: http://www.lg-phones.org/how-to-fix-a-bricked-lg-optimus-3d.html

But, still, no results, I got the following:

Run start_fastboot from the OMAP folder and choose option 2 (P920), enter

Remove the battery from the phone and start pressing the Vol+ button.

Now connect the phone to PC, Omap4boot will flash some files and will wait for 5 seconds for you to plug the battery back.

Immediately plug the battery back

Phone will boot into GREEN SOFTWARE DOWNLOAD mode

After step 4, I had "waiting for device" and could not manage to go any further. Never got the Download mode screen to show up in step 5.

But, after booting the phone, there was a gray LG logo in the center, and fastboot in top left corner....??!?

Anyway... I am sure somthing could be done, but I need to know which one. Also, about the OMAP, found there was a new 1.25 one, instead of 1.21... should I take the newest?

My objective: apart from raise the P920 from the deads, would be move it directly, if possible, to V30A. (V30A Rooted, if possible, even better).

So far I found the following 2 solutions:

1. XBSALL original thread: http://xdaforums.com/showthread.php?t=1942836

--> with his download link: http://d-h.st/RC5 (312MB for the V21E)

2. Yours, 1 year newer, in your thread, a lot shorter, with another download link: http://d-h.st/pCX (342MB for the V21E)

So both are using V21E, there is no way to go to V30A directly?

If not, what is the difference between your solution and with Xbsall's original one? And what is the difference between your V21E and his?

I am sorry for the long post! I hope it will not bother you!

Cheers!!

Sly
[LG Optimus 3D] Karim Kahale:
First of all, I can't see the photo, which means I can't see the error that is showing up.

Second of all, to access download mode, you should insert the battery within the 5 seconds. Sometimes, you got to press the volume up button while doing that.

Third of all, the grey LG Logo means that you are in fastboot mode. You can then install fastboot drivers (included in OS_HACKING tool in my thread) and flash GB bootloaders and cwm recovery by following the instructions. So just check out steps 8-15 in my thread.

For the omap version, I recommend to use always the newest version.

I am using the same bootv21e firmware that xbsall used, it's just compressed as a .zip file.

The difference between my tutorial and xbsall's one is that I have included the OS_HACKING tool step which helps your phone to BOOT. You can also flash cwm recovery which let you flash any ROM you want. There's an extra step too in my tutorial which includes flashing partially the firmware which will write the necessary partitions for bootloaders and recovery. Yes I am using smartflash intead of LG Flash tool in xbsall's thread.

Hope I helped !
