I played around with smartflash yesterday and i checked the 'erase entire cp' which will erase my imei , thinking that it would unlock me full market access because the play store checks the imei to determine the country restrictions . when the phone booted up, it showed a strange korean message which i could not read and the only english letters were 'CP' . i think that had to do with me checking the 'erase entire cp'. now,where ever i go there is no signal , i think my phone is blacklisted because it did not have a imei . is there any way to flash a imei to my phone ?
Well I had to do this when my phone got security error. I found a tutorial in XDA, sorry I'm at school so I can't search it for you but I had to use Hyperterminal (try to Google : restore imei hyperterminal xda).
EDIT : What is strange is that my network was working fine and no strange message was showing, not like you.

Thank you !!!!!!!! but not at computer right now , can't do it
The tutorial did not explain clearly , i cannot find COM settings in hyperterminal and what i type in hyperterminal would not show up . hyperteminal would not detect my device , it only detected COM 17(my phone) in S/W Upgrade Mode .PLEASE HELP , i don't want to spend money buying another phone or go to the service center
So, you need to switch usb mode from AP to CP from hidden menu 3845#*970#. Then when you create a new connection choose com 24 or smth like that. it will work! just try more.

You need a HyperTerminal or other Terminal app that can connect to modem on COM port and run AT commands.
1. Connect phone by USB (phone should be on normally)
2. Enter 3845#*970# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200bps
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. 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
8. Change again from CP USB -> AP USB
8. Restart
You should know that in many countries changing IMEI is illegal!

I now know what caused the problems! It was because i did not disable my sim security before i flashed the ics rom so my phone doesn't recognises the umts network after i flashed it .But after i flashed another gb rom, the problem becomes like pemanent or some sort of thing...............phone still cannot call........The problem most likely had to do with one of the ics roms and part of the problem should be of the 'erase entire cp' thing

i cant do it coz i recieved unknown device alert when selected CP USB
i recieve error when pressing enter after typing the right IMEI.
What should i do?
sorry
i didn't type ","
everything is perfect now.
Thanks
p.s. i used "tutty" instead of "hyperterminal" cause of windows 7
i cant do it ....coz when i go to ur 2nd step ....it says coonection problem or invalid MMI code
P.S my IMEI is not displaying after flashing CM7 ...and i seriously want it back :|
Help rebuild imei after smartflesh tool. Now installed Zeus 2.2 + Hidden menu pack. In "Port settings" i have only three points: "Diag setting" "USB Switching" "Data Setting". "Select CP USB" - I do not have.

update: Found a shift in the "AP CP USB Switchings". Now another problem, I do not see the printed text in HyperTerminal. If i tape "at" blind to dial and press enter, see the corresponding OK.

In the blind well replaced. Thank you.
This was successful as if by magic!
Was really helpful, thank you.

I have the same exact problem and don't know what to do about it. I don't think you can get root as that's not really a terminal??
EDIT: i just got it to work. 2 things I did differently 1) turned off airplane mode. 2) didn't change the baud rate setting to match the one in the lg mobile modem details. probably airplane mode was the problem though . Also, I used the commas, but not one at the end.

thanks, it work perfect.

Hi all,
i have t-mobile g2x (aka p999dw). i followed all steps. For access to hidden menu i typed "1809#*999" (coz my device is 999dw. It appeared and i tapped to port settings. I also checked "retain cp usb after reboot" and phone rebooted. i chose correct port. and in putty i checked "serial" section, then typed comx (which my own), baud rate 115200. Everything fine. When i hit the Enter putty pops-up a window but nothing respond.

How about trying another USB port? Or maybe another PC, if you have the chance, to use another one
Hello,
i had yesterday rooted my LG Optimus Black, after that was all perfect but at the evening i got a big bug.
They didn´t find my sim card. I searched for many solutions.
I have a good one with smart flash but i cant click at Erase Entire CP but i have WIndows Enabler active.
What can i do?
Hello. Just wanted to clarify. You mean that you cannot connect to your mobile network? Any other changes besides root?
Sent from my LG-P970 using xda app-developers app
only root and zeus v7 rom installed
the lock screen shows No sim card and security failure.
click twice on the button
really make sure windows enabler is on
are you on 64 bit or 32 bit?
i have win 7 64bit
after 2 clicks it isn´t activ at smartflash i try it in the next half hour but i think it had to be active to work.
Don't erase entire CP. It damages a partition that can't be recovered (Even with SFT) and a repair person might refuse warranty if they notice.
i have no warranty it was a present but i can´t use sim cards at any kind of rom its say the same.
At a german board the say you had to erase entire cp and after that change the imei to your original imei.

Still damages nvram. If warranty is not a issue then you can go ahead.
Sent from my LG-P970
Sorry, since I needed to do that last year, I'm curious about what damaging nvram implies xonar_ ? Thanks.
Sent from my LG-P970 using xda premium
what's the thing with nvram xonar?
When you wipe CP it wipes nvram partition on your phone ( or at least part of it). All data like mac address of and IMEI are stored there. This data isn't touched by reflashing with SFT. It's possible to read that data from phone to restore it since it's hardwired to the phone, but kernel 3 only reads it from nvram partition. Rmcc made changes to the kernel to make a dummy address if the mac address is zeroed out to allow people with corrupt nvram to use wifi. I don't know if the kernel then later reads it from phone self, but it could cause some problems with wifi and bluetooth.
If you tried flashing the official firmware of KU5900 (kdz or bin not the repack) and didn't change it to fits our device then it also corrupts nvram.
Its possible that ticking wipe CP only wipes the first bit of nvram where the IMEI is stored. There is two entries in nvram that contains IMEI and replacing both of them could 'repair' it then.
I made a backup of my nvram incase something like that happens.
LG R&D tool might fix this,but I'm not sure. It takes forever and I'm making the assumption it's because it does more than SFT.
Here the guide of the german board.
Here is a summary of my approach: (Before installing the SIM card process!)
1) Smart Flash tool load.
3 loading) The image of the LG P970 V20B page.
4) Smart Start Flashtool
5) Erase entire Ap select and process restart select (Previously appropriate COM port) The port will be displayed only if you have installed the drivers and the LG hidden menu of the smartphone "AP CP USB Switching" and "CP USB" selects.
5) Windows Portable load start, and enable the bottom of the icon menu with a simple click.
6) The Windows Portable you have the opportunity to shaded box "Erase entire CP" enable the Smart Flash tool.
7) You select the pre-loaded CP and Ap-bins and start the process. (Before you have to take the battery off the phone, disconnect USB cable, hold the loudspeaker key pushed up, tuck USB cable again. Then the phone is in programming mode, and you can put the battery back.
8) Now click the Smart Flash tool easy to start. After about 5 minutes the process is completed.
9) You should see the SIM error be gone.
10) Note: Since absolutely everything in this process will be deleted right, not the IMEI! This can be changed using a HyperTerminal program again. The right is under the battery.

If everything is deleted then your MC address will also go poof. It can be put back into nvram quite easily. Make a buckup of your nvram so that you can get your Mac Addresses out. (You can get them other ways aswel but I think this is easiest way.)
Code:
adb pull /dev/block/mmcblk0p11 /WHERE_YOU_WANT_IT/nv.img
i have no idea how i can i do it.

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

EDIT: i got tutty, com 4 and 5 dont work only com3 works, com3 command"at%imei" gives me error, and the phone switches from cp image download to cp usb
I have the same problem only my phone never lets me type anything at all into putty, but just like you no new device shows and it always goes back to cp usb.
I also cannot flash the phone unless using CWM. If I try to flash kdz or bin I always get stuck at waiting for IFX modem, if I try using the official lg mobile updater it the install always hangs at 15% and I get message saying phone is no longer connected to pc.

I didn't try this one,
You need a HyperTerminal or other Terminal app that can connect to modem on COM port and run AT commands.
1. Connect phone by USB (phone should be on normally)
2. Enter 3845#*970# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200bps
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. 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
8. Change again from CP USB -> AP USB
8. Restart
Because it fail when i use the ports when .........
If anyone knows help me to write my origianl imei !
Lately i've been watching people as well as myself screwing imei and not getting reception.
There are two cases possible
1> You screw only the IMEI
2>You screw the baseband version also ( which in some cases makes the mobile lag )
Lets start with fixing the baseband version nothing can be done with a simpler way you just have to flash the stock firmware again and the next time you boot the baseband version will appear.
Imei Fixing
Prerequisite
** Make sure you are using Stock rom and Locked Bootloader
1> Install PDA Net and CDC Drivers*
2> Install MauiMeta 3G Software*
3> Download MTK 6582 NVRAM Database* (The Chipset our phone is using )
After you are done doing all these things
1) Open MauiMeta App
2) Click on Action select open NVRAM DB, A popup will appear navigate to the database files downloaded and select the db files and select the files starting with APDB... and the next time BPLG...
3) Click on Option on App and select "Connect Smart Phone In Meta Mode "
4) Select USB COM as your host and click on Reconnect
5)After doing this switch off your phone and connect it if drivers are installed properly the phone will boot in meta mode and the window besides the USBCOM will be accessible click on IMEI Tool if NVRAM DB files are asked provide it
6) Write the IMEI from the Mobile Phones Box (Behind) in both the tabs and press Upload to flash
7) Restart Phone
Voilà IMEI Appears and you can now get Network Signal
AS THIS IS MY FIRST POST AND I HAVEN'T COMPLETED POSTING 10 TIMES IN OTHER THREADS I AM NOT ALLOWED TO SHARE LINKS FROM OTHER WEBSITE WHICH INCLUDE THE SOFTWARE DRIVERS AND NVRAM DATABASE FILE. YOU TOO CAN BE INTELLIGENT AND GOOGLE THEM.
