[GUIDE] Unlock Phone / Recover IMEI

ATTENTION:
I'm sorry I have been busy in the past months and let my xda account unattended. I currently don't own this device anymore. Anyways if someone wants to take over this thread and expand the tutorial by adding a video or photos are welcomed.
Caution:
THIS GUIDE IS INTENDED FOR ADVANCE USERS. A BACKGROUND KNOWLEDGE IS NEEDED. I RECOMMEND DOING SOME READING BEFORE TRYING THIS OUT.
This guide is to recover the IMEI. This happens when the LG Communication Partition has been corrupted, or you have a locked handset example locked to AT&T or any other provider.
Corruption of the IMEI is caused with a bug with the original Froyo firmware. This is provided in an internal use only document from LG but I failed to find the source.
Please be aware that you are dealing with the phone internal hardware and you can really mess up things. Continue at your own risk.
Requirements:
• Latest LG support usb drivers from the LG support site.
• Stock Rom preferably gingerbread v20p.
• Compressed file provided in the attachment section
• TI Omap driver included (OMAPFlashInstaller.msi)
• Infineon Driver included (FlashUSB_x86_x64_Drivers)
Flashing the CP and removing the SIM LOCK
1. Extract the files to a folder
2. Install the OMAP driver (OMAPFlashInstaller.msi) and the Infineon driver (FlashUSB_x86_x64_Drivers)
3. Shutdown your phone and remove the battery. Wait 5 seconds and insert the battery again.
4. Press and hold the “VOL+” and connect the USB cable to the computer and then while holding the VOL+ press and hold the PWR button until it vibrates. The phone should not boot up.
5. Let the TI OMAP drivers install
6. Open Windows Enabler.exe and activate it by clicking on the icon next to the windows system time at the bottom right.
7. Open SmartFlash.exe
8. Under the “Normal D/L” tab double click “Erase entire CP” verify that the checkbox its selected (this will erase the IMEI and any GSM locks)
9. Click on START and wait until it finish
10. Remove the battery and place it again
11. Press and hold the “VOL+” and connect the USB cable to the computer and then while holding the VOL+ press and hold the PWR button until it vibrates. The phone should not boot up.
12. Go to “ROM copy D/L” tab
13. In the “CP bin” choose the file included in "LGP940_CP.rar" (included in attachments)
14. click “Erase entire CP” verify that the checkbox its selected
15. Click on START and wait until it finish
16. Remove the battery and place it again and power on your phone (Write down the IMEI number under the battery it will be used later)
17. Flash a gingerbread KDZ stock rom
IMPORTANT: Some users are having issues with restoring IMEIS using roms that are not supported. If you have a p925 use a p925 KDZ and if you have a p920 use the p920 KDZ
Restoring the IMEI deleted from the previous steps
1. Connect phone by USB
2. Activate USB debug mode
3. Enter 3845#*920# or 3845#*925# or 3845#*760# depending on your model
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
Common Issues:
- On step 9 notice that there is no coma at the end of the 15 digit IMEI number.
- The COM Port connection closes rapidly on certain devices to avoid timeout errors I recommend doing copy paste specially on step 9 also to ensure that you are writing a correct IMEI
- To avoid issues ensure you use a good USB Cable, dont be cheap!!.
- If the device doesn't see the omap device on Windows Device Manager even after enabling show ghost devices on windows you have a faulty motherboard.
- If after selecting the "CP Image Download" mode you see a new com port and gets rapidly disconnected you have a faulty modem thus a faulty motherboard. (Don't know how to fix this, I have only seen this on one device)
DON'T FORGET TO CLICK ON THE THANKS BUTTON
Thanks to IODAK

Thanks

I followed the first steps "flashing the CP" and it seemed to go ok. I thought my IMEI may have been corrupt and it completely wiped it out.
I then went on to restoring and I'm not sure if a new device installed as outlined in step 5. I opened tutty and selected serial protocol adjusted port setting to the only port that would accept commands and got error at step 8 when I tried to display IMEI. I thought this was probably ok since I thought that I had just wiped this file clean and that I need to input the # again ( as in step 9) for it to be displayed.
I assume that in step 10 reset means reboot.
I still wasn't able to restore the IMEI though.
As I am typing this I read over your instructions again and think that I did not separate each number with a comma. Possibly this is the reason I wasn't able to restore? Right now I can't try again because I'm a noob and I've bricked my phone.
Thanks for your detailed instructions though.

You can't start over and try again? At least restoring part?
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

Yes you can start again from the restoring imei part. If you get and error when you input the imei probably is because you are putting more digits than it should (imei = 15 digits)

No, you won't be able to change the IMEI first of all because it's illegal and second it will give you an error

Thank you for the tutorial, I got IMEI Write Ok but still my imei is not restored. I lost my imei while trying update 21e from froyo using smartflash.

try to use a 32 bit windows OS instead, If that does not work, try installing the driver manually from the windows Device Manager.

I WHOLE formatted my Cherry Mobile Fuze Q390 (MT6582) with SP Flash Tool. Then I flashed the official firmware of this device with SP Flash Tool. I don't have any backups because I am reverting to stock. Now the phone works fine but it does NOT detect the SIM card. Also, the IMEI is shown as "INVALID" for both SIM slots when I input *#06#. When I try to fix IMEI from MTK Droid Tools it shows (ERROR : pttycmd1 device NOT found!). Also, MTK Droid Tools shows (Baseband V -----). I am sure the problem is that when I formatted the phone it wiped the NVRAM region too. So the device has no baseband or radio files right not and also the data/nvram/md folder has nothing in it. Although, WiFI still works perfectly except the annoying NVRAM Warning that I kept on seeing when ever that I wanted to connect to a network. Now the official firmware of Cherry Mobile Fuze Q390 does not contain any nvram.bin file. It does contain the BPLGU file but I can't seem to modify IMEI with SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. I tried using the MTK Engineering mode mode also and tried to write it using the AT+ code but it keeps on saying failed to send command. Probably the SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. only modify the IMEI when the baseband or radio files are already present on the phone. So I think the only way out for me is to flash a nvram.bin using SP Flash Tool or Flash nvram.bin+nvram.tar to MTK Droid Tools which I don't have. Any ideas whether I am on the track or not? If I am, then how can I get the IMEI back on my phone. As you people can see that I have tried a lot of things, so please suggest/advice accordingly and any help would be greatly appreciated.

Try using another phone's nvram.bin, which is illegal and modify the IMEI with SN Write Station or any other tools to correspond with that of your phone.

1. check your baseband with mtkdroidtool if it null,you just only use flashtool format it (whole flash) and up rom again,your baseband will return,imei still null.Now you can use mtkdroidtool to re-write your imei,or use Imei & SN writer tool for hard imei.
2.if you still have baseband,just can not write imei throw mtkdroidtool -> just use Imei & SN writer,please install full driver for your mtk devices, include cdc driver

I've tried all the other software like the IMEInSe writer, the MauiMeta 3g, MTK droid tools... none of them worked. But the method mentioned above worked for me.... now there wasn't any NVRAM error in the wireless notification.... The simcard can register to the network as well... this is flawless...
just to share... CPU version showed by the software was MT6572, but if i boot it in factory mode, it tells me its MT6589... I do not know which one is the right one, but the above methods worked for me.... Samsung S4 Korean (clone 1:1) mediatek. running JB Android 4.2.2..

Hello to Xda members,
Since i get a invalid imei issue in my Qmobile A2 so i start searching on different forums nd then i i get this method ,this method is totally of chinese forum (i cant post reference link} so full credits to them but also me
so here we start.
STEPS
1. Make sure you have rooted your mobile and have root explorer installed or similar in your mobile phone.
2. Next download this tool=http://www.4shared.com/archive/ss4A23VB/IMEI_windows.html
3. Open a command prompt
-Press windows key + R
-In the run box type in cmd
-press enter
-A black window will appear with writing
-Enter the following text:
imei.exe <15digit_IMEI_1> <15digit_IMEI_2>
You can use a valid IMEI or IMEI generator to generate random IMEI's using this toolhttp://www.4shared.com/file/zhEXB80K/uig.html
(eg: imei.exe 123456789111111 123456789111111)
4. Press Enter
If both IMEI you gave are in correct format the file named MP0B_001_NEW will
be created. Now you can put it on the sd and insert that in to the phone.
Run root explorer
Copy it to - system need r/w need to be on:
/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
and make sure you rename the file "MP0B_001_NEW" to " MP0B_001"
And finally REBOOT your phone.
DONE:victory:
WARNING

i m agree with u

Is it worked for any one...If yes I would like to try it once coz every time I install new ROM my imei will be lost, since I have backup of IMEI every time I need to restore this backup file from Mobile uncle tool. Which is annoying process after every new ROM installation.

same error here and the driver are installed!

[TUTORIAL][GUIDE] Complete Guide on How to Properly Flash Baseband, IMEI, Wifi MAC, Bluetooth MAC, in Infinix Note 7, (X690, X690B, X690C)

I had an Infinix Note 7, Which I format all + downloaded from SP Flash Tool, everything was gone, after 6 Months of Trial and Error, here is How I fixed it.
BASEBAND FIX:
Prerequisites: Be on Stock Rom, (The one where Baseband was, AKA, the one you were using before you messed up.), Locked Bootloader, Download TFT Tools, (It is a Crack, so No links. Search on YT).
Open TFT Tools, and Go to Mediatek Section.
Go to Bottom Left, and Click Extras.
Click "Fix IMEI Baseband" and insert Infinix Note 7 by pressing Vol+Up Button.
It will take about 2-3 Minutes to fix.
Restart Device.
IMEI FIX:
Prerequisites: Close All Apps, Otherwise the Process may Crash, Locked Bootloader, Download AfterSalesTool v1.5.1, and Modem Meta v10.2044.0.02, and a Valid Baseband (Use Above Method to Fix Baseband.)
To Fix IMEI, open AfterSalesTool, and Select Infinix from the Phone Category, and Select Model as X606, I repeat, X606.
Click the Connect Button and Insert Mobile without Pressing any Buttons.
After 2-3 Minutes, The Progress Bar will become Green, and then the Details of Phone will be listed.
Open Modem Meta Tool. Click: "More" with the Option: "DUT in Meta Mode"
Change the Port to USB, and from Auto Connection to your Device. (Connect Mobile if not Visible).
Click Connect.
It will give an error, Click OK, plug out the Cable from PC, I repeat, from PC, not Mobile, then Reconnect it, and again click Connect.
Now it will completely Connect. Search IMEI Download, And Input ONLY ORIGINAL IMEI, (Check from the BOX BEHIND). (Otherwise, I am not responsible for Thermonuclear War, or Jail, as It is Illegal)
Click Write, 2-3 Times, to make sure, it is written.
Restart Device and dial *#06#, Congrats your IMEI is Back.
WIFI MAC & Bluetooth MAC:
Prerequisites: Locked Bootloader.
Open AfterSalesTool, Select Infinix from Category, Model as: X606.
Click Connect, and wait 2-3 Minutes till it is Connected.
Go to MAC Area, And the Heads are the Prefixes of your MAC Address, The First Head is for Bluetooth (BT Means Bluetooth), and the Second Head for WiFi.
If you have noted your WiFi and BT Mac, Well and Good, Go Flash it.
But, if you haven't, like me, go search for "MAC Address Generator - Generate Random MAC Addresses" and open the website.
Enter the Bluetooth Prefix and then select the format without any colons, or dashes.
Generate it, copy it, paste it in the AfterSalesTool.
If it says, it has an Illegal Character, again generate it, Try again. Keep trying till it successfully flashes.
Do the Same for WiFi Mac, copy its Head, Format without any colons or dashes, and generate.
Keep Trying till it Flashes.
Restart to check your MAC, it will also fix your NVRAM err = 0x10
And Viola, now you have WiFi MAC, and BT MAC, IMEI, and your Baseband Back!
Now Take a Backup through SP Flash Tool, as you Can't Take Any Risk.
Take Backup of NVRAM and NVDATA:
Prerequisites: SP Flash Tool, MTK Auth Bypass Tool, and a Phone with All those things Discussed Above.
Open Scatter File, Press Ctrl+F and search for NVRAM, note down physical_addr, and partition size.
Open SP Flash Tool, and Load MT6768 Scatter File.
Go to Readback Section, and click on add.
It will ask you to where to save it and *WHAT TO NAME IT*, Name it "Nvram.bin" (Name it exactly this or it will not detect in Restore) and click save.
Now it will ask the physical_addr and Partition size. Copy those values and enter there.
Click Ok.
Now click on Add again, it will ask for where to save it, Name it: "Nvdata.bin" (Name it exactly this or it will not detect in Restore) and click Save.
Now it will ask the physical_addr and Partition size, Go to Scatter file, Press Ctrl+F and search for Nvdata.
Enter those Values in the Respected Boxes in the SP Flash tool and click OK.
Disable Auth using MTK Auth Bypass Tool, or if you have Modified SP Flash tool, Disable Auth from there. and click "ReadBack".
Connect Mobile using Vol+Up.
It will back up in the Designated Place.
Restore NVRAM and NVDATA:
Prerequisites: Nvram.bin and Nvdata.bin of a Working Phone, SP Flash tool, and an unlocked Bootloader to avoid Errors.
Let's say you #### up again, and now, your IMEI and everything is gone, you want to flash the Backup now.
To flash it, Open SP Flash tool, and use this Modified Scatter File, to flash Nvram and Nvdata.
If you face any Checksum Error, Download Checksum Generator v5.1932.00, (Search it on Internet LOL) and Extract the ZIP and place it in your firmware, Cut the Original Scatter File, and place it somewhere, and place only the Modified Scatter there, and run the checksum generator as administrator.
Select Nvram and Nvdata Partition, Disable Auth, and use Download Only Mode, and Click Flash.
After 1-2 minutes, it will be complete.
After completion, restart your device, and Viola, Your IMEI and MAC's, and Baseband is back.
I hope this Tutorial Helped a lot of you guys, as there was not much Information for me available on internet on how to fix this exact Model, as it is too stubborn to go in Meta Mode.
If you need any Assistance, Reply to this thread, or PM Me. I will help you guys. Take Care!
