[HELP][SOLVED!] Cannot restore IMEI after downgrading

Hi guys, as I explained in the related thread, after downgrading from ICS to GB my O3D p920 thanks to berni's guide, I'm now having troubles fixing my IMEI.
I followed this guide http://forum.xda-developers.com/showthread.php?t=1734330 without success.
After a short conversation with Pesach85 I noticed that, when connecting the phone to my PC in debug mode it normally detects and installs all the new hardware. But, after dialing 3845#*920# and selecting "CP Download image" from "Port settings", it seems to DISCONNECT ALL THE PREVIOUSLY DETECTED HARDWARE, and installs a new device (Intel(R) flash loader utility).
If someone tells me how to let all the hardware stay connected to my PC, I would be able to fix my IMEI with tutty.
if there's another method to fix the IMEI please write it here.
PLEASE HEEEELP!!

I've been in the same position for a while. Make sure to try the LG Support Tool recovery in S/W mode. (Remove battery, unplug USB, press vol UP, plugin USB - Power + Vol UP. It should show S/W mode. Depending on which loader it should show some korean text).
If you enter your IMEI number to repair the phone it should fix it all. Tho if you came from ICS you might need to do a factory reset after that when the phone boots (it will nag about no space available).

^ +1 This works. It will unroot your phone, but it will restore your IMEI.

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# or 3845#*720# if device is SU760
4.Select Port Settings -> Select CP Image Download
5.A new device should appear at let it install
6.Open Tutty (or hyperterminal) 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

But little changing in the above,
step 3 depend on your phone model or rom in it like for SU760 code it 3845#*760# and for P920 it is 3845#*920#
in step 4 I selected CP USB instead of CP Image Download or CP Reset
Final I was unable to get it to work in Windows 7 so I tried on Windows XP in my office and method magically worked and my imei is restored. I can make call and so on now

hi i lost my IMEI too on my p920 and whenever im using LGMobile support tool to recover with the original IMEI it give's fatal error and nothing.

hey
I not have the SU760 for the long time and was not visiting the forum much, sorry for not replying earlier but it may help other if your problem is already solved
Hopefully your problem is already solved if not, after step 5 check the device manager what your phone is assigned com port com4, com5 or whatever com"xyz" xyz is a some number then in the hyperterminal in All Programs -> Accessories -> Commincation -> Hyper Terminal and in new connection select the com port your phone is assigned whatever that xyz was and start the connection and proceed.
P.S Method not work on Windows 7 so you must be using the Windows Xp

the baseband does not show in Settings=> about phone.
If you want to know your baseband you need to download "Getril" from playstore.
i think you need to be rooted for that to work, but i am not sure.
Also, it is always better to explain the problem you are facing.
Baseband cannot be changed with smartflash. u need LG FLASHTOOL to change the baseband.
please reply with more details like when and how you lost the network.

Hello,
please be specific. what rom are you trying to flash? ICS? GB? CM?
you need to read and understand and only then proceed. I had commented in my earlier reply that you need to reply with more details, but you skipped that part. If this is the way you try to flash a ROM by not reading and following step by step, word by word, you will never reach where you intend to.

[GUIDE] [P720/725/720H] Resurrection Guide (Let´s get those brick´s fixed)

Hello Guys, i have to show you, how you can recover your LG P720/725 and 720H. It´s very simple. Since i have my LG P720 i have reflashed my phone so often by this step´s
there give´s 3 methodes to bring your Smarthphone back to orginal
First what do you need.
First off all you need the KDZ from your Phone and the *.cp and *.ap also the binarys
----------- S/W MODE --------------
Plugged your Batterie out of the Phone. Wait 3 seconds.
Bring it back and insert your USB Cable to the Phone. Then Hold the Volume+ Button for 6 seconds. Your S/W Mode will start.
Now Connect your Phone to the PC, maybe you must install the Driver. (There are in the LG Flash Tool Package included)
If you didn´t flashed your Phone and it´s bricked automaticly , you can use the First Methode
--------First Methode ------
Connect Your Phone via USB to the PC and bring your Phone in the S/W Mode.
Start your LGMobile Support Tool and start the Emergency Mode, it will download the KDZ and flash it new to the Phone.
You have flashed a wrong Bin or KDZ to your Phone? Or Your Bootloader is bricked, also Bootloop ? Use this Methode
---------- Second Methode-----------------
You need the "LG Flash Tool Package" and the full working "LPG720 DLL" you can get the FlashPack here p92x.acidhazardrom.com/ccount/click.php?id=15 . This Includes all relevant Drivers, install it.
Here in the Post you find the LG Flash Tool 1.2 without Drivers
and the DLL are from here http://forum.xda-developers.com/attachment.php?attachmentid=1937519&stc=1&d=1367761284
The SmartFlash Tool http://hotfile.com/dl/143853325/ed430ad/SFT.rar.html Password [email protected]
--If You have a Behavior Blocker on your PC, disable it ---
Install all Drivers from the LG FlashPack.
Bring your Phone to the S/W Mode, install the Drivers.
So after you installed it, go to your Device Manager on the PC and change the Comport under connections > LG Modem ..... to COM41. Disconnect your Phone.
Install the FlashTool, then Start the LGFlashTool.exe from the LG Flash Tool 1.2. Then Select Manual Mode, choose the DLL and add your AP.bin and CP.fls. Press OK. Goto the COMConnector Button and Choose the Port 1. OK. Click on the Arrowbutton , the Program will be ready. Connect your Phone in S/W Mode now to the PC. It start´s automaticly and flash´s your device new.
After your Phone is ready, check your Mobile Network, if its false,"No conenction" you have to reflash the Baseband.
Use the Smartflash Tool, bring your Phone Back to S/W, start Smartflash and connect your phone. Goto the Register Rom Copy D/L under CP Bin use the *.fls binary. Click the Button "Start" now the Smartflash flash´s the Baseband new.
Now Your Phone is NEW.
---------------------------------------------------------------
My Smartphone is Permantently Bricked, bootloop, flashtool can´t flash anything(but i have used it correctly), Kernel Error or anything else
----------- The Third Methode-------------
So Guys, this is complicated for noobs.
You need the OAMP TOOL, download it here http://forum.xda-developers.com/attachment.php?attachmentid=1937574&stc=1&d=1367763391
Now unplug your Batterie from the Phone, and connect it via USB to the PC. Now he will install the Driver, make it manual and choose the Driver from the folder usb_drv_windows, includes in the Package your downloaded.
So now if you have installed the Driver, start the "start_fastboot.bat". Choose your Phone and press the Button on your keyboard, the Tool will bring your Device to the Fastboot mode, if its write to start the mode "Pls wait 5 secondes " is now in the Screen read. Plug your batterie back to your phone.
then choose "install orginal bootloader" and follow the Steps. After you have to all, bring it back to the S/W Mode and follow Second Methode.
------------------------My S/W Mode is Gone-------------------
Follow Third Methode, but hold your vol up button permanetly , this will bring your Phone to the S/W Mode.
----------------------- Nothing goes, i think my Device is Bricked permantenly, fastboot can find any partitions or any thing else--------------------------
After i had this Problem, i fixxed it. So start Omap, choose your device. Hold permanently your Vol up button, plugg the Cable to usb and insert the Batterie. Omap brings your phone back to S/W.
Now flash your Stock Image with FlashTool, maybe 3 Times.
It works for me
----------- Other Mode KDZ_FW_UPD ---------------
i have forgot to tell you this mode. For this you need the KDZ File.
Download http://forum.xda-developers.com/attachment.php?attachmentid=1949514&stc=1&d=1368135582
Its the same methode with the LG Mobile Support Tool, but offline.
Bring your Phone to S/W Mode and connect it to the PC.
First you have to edit your hosts file. Open it and insert this 127.0.0.1 csmg.lgmobile.com
then start kdz server, start windows enabler. See at the Tryicon click on it and make it ON.
Then open UpTestEX_mod2_marwin
On the rigth side, click on select kdz file. Choose your KDZ.
On the Bottom start "normal web upgrade test"
Then Upgrade Start.
The Mobile Support Tool opens and flashs the KDZ
This was a short Guide to bring your Phone back. If You have questions so ask pls =). Btw sry for my bad English, but i hope you can understand it
Added CWM for P720 maybe P920

Hi,
How do I get the binary files?
Also, the SFT.rar file is asking for a password.
If I have the KDZ, .bin and .fls files, i can use this method to upgrade to later version of software as well ( I am on V10C on P725, I can use this method to upgrade to V10F as well)
please help.
schubeir

ok if you read the Guide you find
The SmartFlash Tool http://hotfile.com/dl/143853325/ed430ad/SFT.rar.html Password [email protected] <<<<<< Passwort
the Binary files are from the KDZ, you musst extract them with LG Extract Tool
you can Use SFT or LG Faslhtool to flash you binarys.
If You have only the KDZ Use KDZ_UP......

Good Job !!!

Dear MasterTobi, hello!
I am trying all these methods, but I can't unbrick my phone! I can enter 2 different screens for S/W Upgrade, one by normal mode, another by OMAP boot mode, bu tin anyone my phone goes live... Do I have to select the port 41 in LG Modem in Device Manager, and after this, port 1 in the LG Flahs Tool? Is it correct? When I try to do this, I got the message "Downlaod Fail" each 20 seconds in the port 1 field at the LG Flash Tool.
I tried the methods in this post and another ones, but anyone works for me. Do you have any idea?
Thank you very much!

Sorry, but if I use your DLl, I got the message "Model Name is different! Chel phone or DLL!".
Also, I tried the smartflash tool, selecting the ap and cp. At the ending, appears a mesage "Magic number doesn't concide".
And finally, I tried the "Normal web upgrade test". This one looked as my phone would return to life, but not...
In any of methods I could turn on the phone. I don't know what I can do know. I am very, very afraid...

My guide is similar to the Resurrection guide which supports 3D MAX, the difference is that I've added some different steps and a slightly different method.

My phone is a 3D MAX, a P725.

oh guys...............
so you have a magic number ........ strange, there is only the error if you have a wrong version
you have to download the LGP720AT-00-V10e-EUR-XXX-JUL-17-2012+0_AP this is for the P720/P725 alias 3D MAX

Success!
Hey people! I got success! After many days trying, I unbricked my phone! I will tell you what I did.
- My phone is a P725. I don’t know exactly where is it from. This information (P725) was very important for me in the unbricking process.
- I used the LG Flash Tool 1.3.77.21 (http://forum.xda-developers.com/attachment.php?attachmentid=984864&d=1333650043).
- Now, the two cheats that helped me to unbrick my phone:
1st: I didn’t use the .dll from the first page of this post, and I didn’t use the .dll, .bin and .fls extracted from the KDZ gotten from the IMEI of the phone. They didn’t work for me. I googled for these files for P725AT, which was the model that LG Flash Tool was telling me that is my phone. I found the following files:
http://freakshare.com/files/e6xssy95/BIN_LGP725AT-00-V10b-ARB-XXX-MAY-08-2012-0.zip.html
http://uploaded.net/file/v6orqts2
2nd: At the flashing process, there is a pause at 80% telling that the phone will reset. In some cases, the reset really occurs, but in my case, the reset didn’t occur. A lot of errors appeared (see the image), but no problem. I just turned on my phone, and BINGO! It was working again.
It’s important to tell that I had to put my phone in download mode using the OMAP TOOL, that can be found in the first page of this post (http://forum.xda-developers.com/attachment.php?attachmentid=1937574&stc=1&d=1367763391). Don’t forget to change the LG USB COM Port to 41.
That is my history! I hope that this help someone. I would like to thank everybody who wrote about the brick of this phone (MasterTobi, Karim Kahale, Eklovya Dutta [I'm not certain of how to link for them, sorry!] and anybody else), I believe that is one of the worsts bricks in smartphones…
Good luck for all!
EDIT:
I forgot to tell: all the process was made in a Windows 8 64 bit. It gave me some difficults to install all the drivers, but it is possible, Google it and found how to.

Then you will see three option something like Recovery, fastboot, factory...
You have to choose fastboot option...
when fastboot is selected then connect your phone to PC via USB cable...this will install some helpful drivers to your PC....and then again try the flash method without battery...

yeah, everything was according to the tutorial. phone was detected, first red, then blue then yellow progress bar & finally green circle. I removed the usb & reinserted the battery after flashing then pressed the power button. Karbonn animation shown & stuck at the eye screen. After a number of failed attempts I decied to erase the whole device & then flash again. I erased flash+bootloader. The phone is dead now. not powering up. But if I connect the phone via usb to pc a beep sound is heard. Any clue, how to restore the bootloader?

Thanks a million times man for your suggestion.
I tried with fastboot but no device shown. I went to device manager & uninstalled-then reinstalled the drivers. That actually helped me to build the serial communication between SP flash tool & Device.
Then I discarded the battery & retried the SP flash tool, this time the phone is finally detected & flashed successfully. red, blue, yellow bar then green circle. DONE.
Now, the same issue. Karbonn boot animation is displayed & stuck at the eye screen. I have covered the halfway but cant be able to get success in the other half (cant see the homescreen or anything.)

[Guide] Unbrick Your UNLOCKED Lenovo P2a42

Hey Friends,
You must have seen very good days with Lenovo P2 but when there comes a bad day when your phone stops responding to button holds and restarts. You may or may not have a clue what to do to get your phone working again just like before.
I got into this situation where only thing my phone was able to operate was a RED LED on connecting it to my laptop. Then I had to read tens of pages on XDA to find answers to all my questions. If you are in such a situation and your phone is UNLOCKED then you have come to the right place. Procedure is quite simple but remember, I am writing this guide to define complete process from blackout to complete update so follow this guide as per your needs.
I faced this situation of Total Blackout / Dead Phone (Almost) with only Red LED working and it can be very scary. So, here is the simplest procedure you can follow. I want to appreciate all those people who helped me in finding a way to boot my phone with each and everything working. Long story short, let's get this done.
Tools Required:
I am mentioning here all the Tools you will need. I will urge you to download and save these tools in case you want to unbrick your phone any time:
1. Minimal ADB and Fastboot setup for PC
2. Lenovo USB drivers v1.1.33
3. Qualcomm USB Drivers
4. Qualcomm Flash Image Loader (QFIL) v2.0.1.9 for your PC in case you have corrupted your phone's IMEI and/ or Baseband
5. Blankflash.bat in case you want to recover from total blackout (Attached)
6. Stock MM S048 Firmware for Lenovo P2 in case phone doesn't boot
7. S048_ModemTelephony.zip in case your phone boots through Stock MM S048 but SIM isn't detected and IMEI is missing. I have made a complete modem zip file for installation through recovery.
8. S251_ModemTelephony.zip in case your phone is on latest firmware and doesn't detect SIM and has lost IMEI. I have made a complete modem zip file for installation through recovery.
9. QCN file for recovering baseband version and giving you most precious network signals. (Attached)
10. WinRAR or PeaZip for uncompressing files
I will recommend you to have a specific folder for keeping all these tools in a single place.
Procedure for Unbricking:
Before going with the procedure, make sure you have downloaded all the files you need, updated Lenovo and Qualcomm drivers etc. Here is the procedure:
1. If total blackout with red LED notification when connecting to PC: Unzip blankflash.zip to a folder in C drive. Now connect your P2 to PC through USB, press volume+, volume- and power button simultaneously and double click blankflash.bat. You might have no success in your first try. Just keep trying and it will load your phone to Fastboot. Restart your phone in TWRP if installed and install a working ROM for your phone after doing a wipe. If all is good and phone works OK then great but if you have lost IMEI and baseband then it is better to reinstate your phone through first MM stock ROM S048
2. Install S048 firmware through Minimal ADB and Fastboot - use flash instructions in .txt file.
3. Wait for startup of phone. Check if fingerprint, BT, WIFI and SIM work if all work then OK.
4. If fingerprint, BT, WIFI and SIM are not working then check IMEI through dialer. Dial *#06#. If IMEI is not available then install latest TWRP through Fastboot.
5. Start P2 in TWRP recovery and install S048_ModemTelephony.zip. Restart phone to see if WIFI and SIM work.
6. If SIM is detected but not giving signals and Baseband is shown as unknown then extract 000000_0.qcn file given in .7z and restore through QFIL and restart your phone into Fastboot.
7. Now, install stock recovery of S048 firmware through Fastboot and restart your phone.
8. Use your phone like you normally do and update your P2 till firmware S251 and see if everything works including calls. Update your phone through OTA.
9. After OTA installation, stock recovery may say that update failed. Just press Back, go into Wipe user data menu and Wipe Cache only. Restart your phone which will be updated to latest version and will ask you to update to a newer version. Allow it to download the next update.
10. After installation of S251 update, install latest TWRP through Fastboot and install most recent version of LOS 16 so that your vendor partition is stable and free from any bloated files. Now, use your phone just like you want to.
If you need further clarification then ask in this thread.

You should download S048 and use flashall.bat inside that archive to install it all. However, if you lose IMEI or baseband then you can use modem and qcn files given in this thread.

If red light blinks, your phone can be detected by your laptop. Check ports in device manager settings and you'll see a new port with Qualcomm 9800 series number. If that's there, try blankflash to start in fastboot. It might need some tries before startup. Be patient and keep trying till you are in fastboot.

Press Volume+, Volume- and Power simultaneously and double click flashblank.bat. It might take some tries to finally install the scripts and start phone in fastboot. It took me 20+ tries to finally detect my phone through blankflash. Please, read OP completely.

No. Keep USB connected. Try blankflash. If it doesn't detect phone or go ahead. Close command terminal, double click again and keep doing it till it processes the files. If it is stuck somewhere. Close terminal and try again.

I think you might have damaged some hardware. But anyway if you want to use blankflash, I have a method.
In lenovo p2 we have another mode called QDloader mode, in which we can use blankflash. For entering into this mode, it's little tricky but, can enter in one or two go.
So, here's how:
1. Switch off the mobile.
2. Press the volume up key,
3. While holding the volume up key, insert the usb cable and at the same time press the power button (this is the trick, we have to insert and hit at the same time).
And voila! :highfive: you will see black screen with only red notification led blinking.
we are into QDloader mode. Now use blankflash :good:
