[LG Optimus 3D] AndroidLover813:
Okay peoples I was able to unlock & restore my IMEI. It took two days for it to work but with due diligence I was able to do it.

First off I would like to thank all the developers involve with this task. I know it wasn't easy but thanks for all the hard work.

My process went as follows:

First off write down your IMEI # cause your gonna need it.!!

I followed all instructions up to the part where we need to restore our IMEIs that's where it got interesting.

I tried using tutty to rewrite my IMEI but for some odd reason it just wasn't working.

I did a lot of research and found the fix:

Thanks for the find...

You have to use LG MOBILE SUPPORT TOOL.

Put your phone in download mode and upgrade your device and that's how I was to restore my IMEI and it also upgraded to ICS which I don't mind and it did retain root and Sim unlock.

I don't really know how it worked. All I know is it did.

I now have an Sim Unlocked LG Thrill 4G on T-Mobile. I will upload screen shots shortly. My nephew is the first to use so I'm testing it with him.

Thanks XDA, without this forum all our phones would be paperweights, instead our devices take us places we never thought possible....

Update : upgrade does not retain root so your going to need to root for ICS 4.0

I tried to recover my imei but I got stuck at number 6. There's no Tutty to open. What went or did I do wrong?
[LG Optimus 3D] Gilbertvanhaasen:
I'm sorry about my former post :eek:, I found Tutty and when I'm at point type AT and press enter it says OK. So far so good.

But then I type at%imei and then enter my original imei number is showing instead of a dummy. The next thing I do is typing at%imei=(here now my original imei number found under the battery) and press enter then it says IMEI WRITE ERROR.

What went wrong? I feel I'm so close now. Please what am I doing wrong here?

Is it possible you get me a link with the right KDZ file for the P920?
[LG Optimus 3D] iodak:
You will newer be able to repair it if it still report IMEI. That was mine problem in first place, then I finally found a solution. You will need to somehow reset IMEI. There are two ways: flash baseband from prada (p940)

Flash p920 baseband with smart flash tool and select to delete baseband. (format CP i think)

Anyway you have to have IMEI some generic number. Then command write IMEI from terminal will be success .

LG optimus p920

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 a dummy 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 (found under the battery of your phone). It should response IMEI WRITE OK

10.	Reboot phone

OK I've completed all the previous step but stopped here

When I enter my IMEI in Nutty it keep saying IMEI ERROR

I'm pretty sure that I'm typing the digits correctly

I've already restored my IMEI the problem is another IMEI SV is 00

Please could you respond to my request

Thanks in advance :angel:

good work!

[LG Optimus 3D] realbabilu:
Thank you it works.

Note:

First

The author is clearing the imei with the Clear CP. or resetting

The author is injecting 940 baseband for a bait.

So the KDZ reflashing with LGmobile support tools is a must for resetting back to P920 original baseband.

The imei inserting is using the com port that not listed on device manager, and without KDZ stock flashing, it will never came up with port.

it is not the same port for flashing.

That port, for me, is port 5. then can be injecting at%imei= ....

Custom rom and IMEI

The question is as simple as it can be i'm custom rom cm10 and the problem is same unknown IMEI can I just go over the IMEI recovery steps i mean recover IMEI without having to go to stock or flashing some kdz files.
[LG Optimus 3D] cyclonmaster:
Using Windows 7 x64 Pro.

Follow all step, flash V21D <-stock gingerbread.

4.	Select Port Settings -> Select CP Image Download

5.	A new device should appear at let it install

at this stage, it did install new device which is "Intel(R) USB Flash Loader utility"

Is this correct?

Now I stuck at this stage:

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 a dummy 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 (found under the battery of your phone). It should response IMEI WRITE OK

10.	Reboot phone

What is the name of the serial port suppose to be? LGE CDMA USB Serial Port? LGE Android Platform USB Serial Port?

I had no serial to select under tutty after Select CP Image Download. Any hints?

Thank you.

[LG Optimus 3D] tudor.raneti:
I have P920, no IMEI, possibly wrong baseband (L6260_MODEM_SIC_01.1042.00)

I've done the above steps so that at%imei (all caps are needed), shows my actual IMEI which I set from the back of my phone.

I rebooted and phone still shows no IMEI. What am I suppose to do?

P.S. Phone doesn't want to enter download mode no matter what I push, so I can't install kdz's. I'm installing roms using CWM...
[LG Optimus 3D] josuelopezv:
you need to have the original base band and firmware of the first release of your phone for this to work. they have patched the flaw

Think flashing v10 will help? I've flashed v20d lately, supposed to be latest original firmware for p920. Now tutty refuses to start... and IMEI still not existing

P.S. I've used this handy tool to extract bin and fls from kdz: https://xdaforums.com/showthread.php?t=2245469

Perhaps I'll try v10L (my original phone was from Orange): https://lg-roms.com/official-firmware/LG Optimus 3D-LGP920/V10L/FRANCE

Also I've made a CWM restore point which refuses to restore under any circumstance :-/

EDIT: after flashing bootv21e from the guides, I can enter download mode as in the pictures

EDIT2: after flashing v10L with this lg flash tool: https://xdaforums.com/showthread.php?t=2797190

and recovering from bootloop with this: https://xdaforums.com/showthread.php?t=2426426

everything seems to be back to normal, imei files rebuilt, phone signal... had to spam tutty to start properly seeing the right port (15), then spammed at%imei to set it because it gave me error or ignored me :) IMEI set properly too now...

Last problem is, how to properly flash an updated firmware for LG 920 w/o losing any functionality. Also, are v2, v3, v4 firmwares for LG better for it's battery life?

[LG Optimus 3D] josuelopezv:
Try using the original imei in the battery cover of the phone
[LG Optimus 3D] josuelopezv:
First of all I think that in almost all countries this is illegal. Second, Imei numbers have a checksum auto included so you can not get creative writing an IMEI. Third if another imei is already on the net it will cause you issues. Conclusion use the same imei included with your phone.

Question here, smartflash just shows AP and not CP erase. Was this a misspelled or what?

Anyone? I just want to know if he reffers to clicking on Erase entire AP, since im not able to find Erase entire CP....
[LG Optimus 3D] enelyam:
Ok let's see if someone helps me which is getting kind of difficult. I have this p925, it is on Froyo but the phone has no IMEI and of course no signal. Found this thread with the help of a member here but still having a bunch of issues. First, i follow the proccess but then when i open Smart Flash theres no option to click on erase entire CP. In fact, no erase CP option at all. There for, I cant go on with the method mentioned at all. The phone wont flash kdz and or fls. But it goes to download mode ok, And i managed to install CWM on the phone. Other than that when i try to flash using smartflash it runs normal until sends an error and thats it. Nothing can be flashed. Question is, is this a complete bricked phone or is there a workaround. Please help me on this

Edit: Dont ask me how the phone ended up with no IMEI because i dont have a clue. It was given to me as is
[LG Optimus 3D] wayno140:
It may have been flashed with rom based on wrong baseband ie a gingerbread rom on froyo device I had no imei error I believe once when I flashed wrong rom by accident try to flash a rom for froyo and see if imei returns

Edit: do not erase cp it will brick your phone and there is no repair ask the dark lestat I believe he bricked his with a erase cp script
[LG Optimus 3D] enelyam:
Ummm, thanks M8, and yes, it happened to me before that ive seen phones with gingerbread baseband and ppl flashing it with Froyo it will end up with no IMEI. But the thing is that Ive succesfully done that before and solve it. In this case, for some reason, the phone will not flash with KDZ and or fls files stock. It shows on device manager and stuff. In fact it starts flashing. But once it gets to about 50 percent it sends an error and wont flash... So i have not been able to flash anything using KDZ and or smartflash tool. Thinking about creating the cable that forces the programming but im running out of ideas in order to flash gingerbread back to see if it shows the IMEI again.

Edit: It says cant communicate with specific port. Could this be a driver issue or something? I mean the phone shows on COM13 and all. But when its flashing it will show that error message. Driver missing?
[LG Optimus 3D] enelyam:
Ok, when it seems to work. This is all it will do. Seems like either a driver missing so that smartflash can communicate with the phone. Or the phone is really messed up and its disconnecting itself. Strange thing is that it will boot normally and everything.
[LG Optimus 3D] wayno140:
Try to uninstall all LG drivers and start completely over with lestats guide in either thrill or o3d development sections if you are missing a driver it should reinstall all of them needed otherwise I don't know maybe send lestat a pm and request team viewer
[LG Optimus 3D] enelyam:
Ok thanks, well, i have an SeTool on the way. So if not, ill wait for it to see if theres something i can do with it
[LG Optimus 3D] enelyam:
Ok so this is the error im receiving when trying to flash the P925. So if someone have experience this please help me because ive spent two days trying to flash it and wont get pass this. Unistalled drivers and reinstalled them dunno how many times now. And no matter what this is where i end up. In other cases the situation shown in the earlier post.

That error shows after the first 45 or 50 percent flashing by the way. It doesnt happen right away
[LG Optimus 3D] wayno140:
Its a time out error something is taking too long and making the tool time out I believe I don't know I would pm the dark lestat and ask him to teamveiwer you he can fix it I am sure
