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.

Hi Friends,
This is my first post at XDA.
I unfortunately bricked my Panasonic P81 after rooting it and adding XHalo app and the boot manager app from the Xposed Framework.
The situation is as follows-
I can get to the logo, it screams Panasonic and then doesnt boot. I dont have CWA installed and worse, my SD card which had my stock backup is also lost. This means I need a mechanism to stock recover and perhaps flash boot.img and recovery.img?
I am stuck at this point, not sure how to proceed. I can get to recovery, have cleaned cache, backed up user data ,done a factory reset. Even after factory reset it still cant boot.
Please help me with a step-by-step instruction to recover, this phone is dear to me. How do I flash?(boot.img or rom) I have downloaded Sagar Patel's (good bless him!) backup and the images, but need guidance on how to flash and recover.
Please help friends and apologies for any incovenience. I am still a newbie
Guys please help!!
Driver-USB-PC connection problem
kartik.krish said:
Guys please help!!
Click to expand...
Click to collapse
Hope drivers are installed properly in your pc.
If you are going to use sp flash tool, Make sure SP flash tool is set to auto-detect com port, not manual selection
If you find that it is driver problem, following may help you.
Please note that there is nothing that much hard in driver installation as it is just to connect your device with your pc but because many users still face problem of driver installation, you can try following tricks!!!
It is observed by me that driver installation and adb interface problem do not happen in windows XP as eventually and generally it is happened in windows 7 and later…so, you can simply try on windows xp if you are able to do so…(you can use dual operating system too!!! Or good relation with neighbor/friends/colleagues/someone/all can be beneficial here!!!)
Note that all tricks here are not necessary to work, but it may still work for you….
Take one by one step, if the first step does not work for you, only then try next step. This is not all steps to be taken at once type guide…This is simply Try and error type tutorial/tricks…
There are following problems I have come to know regarding to driver installation and conflicts:-
Device is charging through usb cable but there is no usb option displaying on either device or no driver installation box/message/pop up appears in pc….
Missing sound of that usb-pc connection
Sound of disconnection after couple of seconds of connection
Adb interface is missing
Ok, sometimes changing usb connection type for example, from mass storage or mtp to camera, ptp, usb tethering or something else can bring adb interface…..
Try with different USB Cable. You can use original nokia or samsung tiny cable instead of cable having long length. Sometimes, length matters!!!!
Try in different USB Port.
Sometimes, you have to disable signature verification in your pc for proper installation of driver.
Had you disabled your antivirus before downloading, installing and while running your tools/softwares? You may need to do so…
Have you installed the software (or say, all associated softwares/tools) in C-System drive?, if not, then you should first install required software/tools in system drive that is usually C drive in Microsoft-Windows OS…or try after installing them on desktop.
Keep all necessary files/tools (driver files, flash tools, rom etc…) on desktop.
Download proper driver According to your model/device, According to chipset inside, According to Official site of manufacturer, Official site of chipset, through PC Suite/flash program of your device…
If the problem still not solve, you should try all available driver packages of your device one by one whether from official site of chipset inside your device, or any forum, adb, pdanet+ or foxfi, universal driver, VCOM Port driver, drivers from hexamob through play store, and find all possible packages and see if someone make positive result after installation…
If the problem still not solve, you should install remaining update packages of your system (PC) including all primary, secondary, essential, Non-essential updates….whatever, just install them all….reboot your pc…and see if problem is solved….
If you can connect the device but somehow found that device driver still not installed properly, just go to device manager in your pc, click on portable device, right click on your device and apply “Update driver”. Click on “automatically search” when a window prompt ask you.
If the problem still persists then,
Just remove all the drivers using usbdeview (I have given link also to download usbdeview in earlier post)
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Install usbdeview and remove all the drivers
You can also fix this by showing the nonpresent devices in devicemanagement (google for show nonpresent devices for explanation)
Go to com ports, and delete all mediatek drivers except preloader driver. Now start over. It can help if you choose the same usb port where you had success last time.
Use Usbdeview to uninstall all the drivers before connection, restart the pc, Extract and keep driver zip files and other useful files/tools on desktop…just start your tool… and try to perform your tasks like backup…or restoring the backup…without worrying about that sound of disconnection you may listened after couple of seconds of connection or don’t even worry if you are just missing that sound of usb-pc connection….just try on your tool…
If still problem of driver installation persists, then simply use usbdeview and uninstall all drivers, restart your pc and try following steps:-
There are various ways to install proper drivers at the time of connecting the device with pc depending upon how you connect it.
Follow the procedure both with and without battery
Simply plug in via USB Cable
Connect by holding volume down button
Connect by holding volume up button
Connect by holding Power button
Connect by holding power and volume down
Connect by holding power and volume up
Connect by holding both volume up and down button
Connect by holding thrice volume up, down and power button
Connect by holding power and home button
Connect by holding power and menu button
Remember which method works and which drivers are installed
in LAN-Devices you may have different android device
Select/set drivers by hand and use the mtk usb driver, now Flashtool finds the phone
Suppose holding volume down method without battery works for you then what next you have to do is as below:-
1.TAKE THE BATTERY ,SD ,SIM OUT OF THE PHONE
2.HOLDING VOLUME DOWN CONNECT IT TO PC VIA USB(ONCE YOU HEAR A SOUND FROM PC YOU CAN RELEASE VOLUME DOWN)
3.OPEN DEVICE MANAGER(ON COMPUTER SEARCH IT OR CONTROL PANEL)
4.WAIT FOR 2-3 MINUTES
5.YOU WILL HEAR A SOUND & OTHER DEVICE WILL BE DISPLAYED
6.IN OTHER DEVICES ->MT65XX PRE-LOADER
7.RIGHT CLICK MT65XX PRELOADER
8.UPDATE DRIVER
9.LOCATE THE DRIVERS PROVIDED ACCORDING TO YOUR OS(VISTA,WIN7,XP)
10.IT WILL DO ITS STUFF
Install Mediatek drivers, preloaders, VCOM port etc…
Manually Install MediaTek USB VCOM Drivers
Requirement:-
1. Download MediaTek USB VCOM Drivers
2. Download USBDeview
Here is the link from you can get it:-
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Procedure
(* Note: You might need to disable drivers signature verification in Windows for this to work smoothly.
If you want to turn off device driver signing in Windows completely, do the following.
Windows 7:-
1. Hit the Win+R keys together to open the run dialog
2. Type gpedit.msc to open the local groups policy
editor
3. Expand ‘Administrative Templates’ (it’s under ‘User Configuration’)
4. Expand ‘System’. Click ‘driver Installation’
5. In the right panel, double click on ‘Code Signing for Device Drivers’
6. Choose ‘Enabled’ in the window that appears.
7. In the underlying options, choose ‘Ignore’
8. This disables drivers signing in Windows 7, and now you can install unsigned drivers in Windows 7.
9. Click Apply, OK. Restart your computer to install unsigned drivers
Windows 8
1. Hold down the Windows key on your keyboard and press the letter C to open the Charm menu, then click the gear icon (Settings)
2. Click More PC Settings
3. Click General
4. Under Advanced Startup, click Restart Now
Note: In Windows 8.1, the ‘Restart Now’ button has moved to ‘PC Setting -> Update & Recovery -> Recovery.’
5. After restarting, click Troubleshoot
6. Click advanced options
7. Click Windows Startup Settings
8. Click Restart
9. After restarting your computer a second time,
choose Disable driver signature enforcement
from the list by typing the number 7 on your Keyboard Your computer will restart automatically.
10. After restarting, you will be able to install
unsigned drivers normally; however, Windows
will display a warning message. When the
warning appears, click Install this driver
software anyway. )
1. Install USBDeview and use it to uninstall all Vcom, Mediatek and Preloader drivers
1b. Extract the contents of the Mediatek USB VCOM file
2. In Windows, go to Control Panel and open Device Manager
3. Click any of the device groups (any of the items on the list) you see there, and then from Action menu, select Add legacy hardware
4. Add hardware wizard will be opened, click next
5. Select Install the hardware that I manually select from a list (Advanced)
6. Click next two times and click Have Disk button
7. Click browse and find where your driver's .inf file is, then select it (the .inf you'll select is located in drivers > USB Vcom driver > your OS) . Ensure to select the 64 bit .inf if your PC is 64 bit
8. Click Open and OK. You will see the drivers listed.
9. Select your driver there (select Mediatek Preloader USB VCOM Port)
10. Click Next and finish installing
11. If SP flash tool or other software still dont detect your phone then also install Mediatek DA VCOM (consider installing more from the list of drivers one at a time if need be)
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Case:-
It did the same thing with my MT6577 (Wiko Cink PEAX), so I connected it with a battery and without holding VOL+. Then "MT65xx preloader" appeared in device manager then disappeared (once). It is normal that it disappears. When you start Flash_tool and when you click Download (or whatever you want to do) THEN you connect the phone (in off state), and the flash operation will succeed.
Guess what? Once my Panasonic P81 could install driver and got detected after approx. 5 hours of continuous connection with win 7 x64!!! Meanwhile, I tried first usbdeview and then manually installation of mediatek driver but manual installation had failed as my p81 was only charging when it was connected with pc….So, mediatek – windows 7 conflicts….but, when I tried tiny (very small) nokia usb cable, it works instantly…
If you ever meet problem when you connect your android with your pc via usb cable and find that your android is charging but could not recognize or there isn’t that options of “USB connection” then just disconnect your android, power off it, remove battery, connect it without battery with your pc through usb, let it have some time to recognize your android or hear that voice of “usb connection” you were just missing…after that, insert battery and switch on your android…you are done!!!
Sometimes removing both sim cards and battery and then re-inserting them after a couple of seconds also works.
Try with different USB Cable
Try in different USB Port
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Use usbdeview to remove all the usb devices and then add your device
Find proper driver of your device:-

In my opinion MIUI is best because it has a self large community like xda and launch updates per month so many that you will fed up installing them.....if you download and install one update you will be amazed that it will say 3 more system updates pending......and if you complain a bug next month it got fixed.....only thing is to find one...
PS don't download the miui 6 for p81..complained by many p81 user that it hard bricked the device.
And that miui is not official i.e. some developer made his own one and DO not tested that it works or not......

One week after i brought my phone, I accidently formatted my device using sp flash tools and lost the IMEI/NVRAM. It has been a real pain for me to repair it because i was new to an mtk device. Finally figured out how to repair by doing many search. So I made this thread to share the working methods to help those people who are suffering from invalid IMEI
So let's start.
Always remember "Prevention is better than cure". If you are planning to flash a custom rom, First of all Backup your IMEI. Don't Trust that a custom ROM flash will not delete your IMEI number. because odds are it will. It's important to store your backup to external SD because some ROM flashing techniques will erase your internal SD. so the best way to keep your IMEI number is to take my advise and make a backup.
Some Video tutorials will be added soon
DISCLAIMER: Do not do try any of these methods unless your IMEI has been lost! Doing so may permanently corrupt your imei partition.

I tried this method but every time I tried, I was getting "Entre Meta Mode Failed" I am unable to understand why my device is not going into meta mode. I have written IMEIs and MAC IDs with this tool on Canvas HD, hell lot of time.
The process for Canvas HD is little different, I used to select both the database files, first "BPLGUInfoCustomAppSrcP_MT6589_S00_MOLY_WR8_W1248_MD_WG_MP_V6_P18" and then this one "APDB_MT6589_S01_MAIN2.1_W10.24" secondly I used to power on my device "Power On" msg was displayed on SN Write Tool.
I tried all possible scenario, selected only one database file, changed the sequence of selecting database files, tried to turn it off after hitting start but worked nothing for me.
When we select Database files the window opens twice, did you select same file both the times? And have you tried to write all the things together, means IMEIs, MAC ID of BT and MAC ID of Wifi in just one go?

Yes i select same file for twice name of file is given above in my post and i never try to write other things like bt address, imei same time but i want to say don't try to write bt address because it will show error every time when you try to write and i also want to say that imei number can be written with this tool but select only imei don't other things like sn number, wifi mac address.......etc. try one thing only at same time. means when you want to write imei then select only imei but you can choose sn and wifi mac address at same time it can be flashed successfully......

Hello , after alot of research online I've managed to come up with a way to unbrick my hard bricked device Sky IM-A770K in qhsusb_dload mode with dead boot ,without having to send it to those jtag/medusa services with the help of some methods i found on some vietnames websites . Ok so before we begin I hold no responsibility for the damage that you're device gets so follow the steps exactly as I say .
So this is the ultimate guide to unbrick your IM-A770K or IM-A760S device from qhs_usbdload. :fingers-crossed:

3. Open device manager. Device should should show as qhsusb_dload.
4.Click on device and click update driver browse for the files qhs_usbdload and chose the driver accordingly to 32bit or 64bit system.

11. If asked do not format. If device boots up do not attempt the following.You've fixed it . If not continue with below steps.
12.This is the hard part you should be careful with this could damage your internal emmc partitions permanently.
13. Install winHex from winhex folder.
14.Open winhex as administrator.
14.5.Warning this step is for sky im a770k or 760s only if you have another device please do not attempt it as you may damage emmc(sdcard) permanently. Thank You.
15. Select File->Restore Image->Browse to the downloaded files of my guide(Change File type to .01,.img,etc)->Select unbrick770k760s.img. Open.

Hello,
My phone can be charged though usb , but can't be used to transfer data.
If somebody can help me undestand.
PHONE IS NOT ROOTED
What i've tried:
1. Using all combinations posible with the *#0808# code.
2. Reinstalling another firmware with ODIN - XEF , BTU , etc.
3.Trying another cable/cables
4.Trying connecting to other PCs
5. Tried to connect with ADB in RECOVERY MODE
6. Tried SAFE MODE
7. Tried Debugging mode
I've used USBDeview - small utility that lists all USB devices that currently connected to your computer, as well as all USB devices that you previously used.
THE DEVICE CAN BE DETECTED IN ODIN MODE , TRIED INSTALLING VARIOUS FIRMWARES in DOWNLOAD MODE
Any advice please , post it here.
I'm disperate because i can't understand why it does work in DOWNLOAD MODE .

i've added a picture with the USB LIST when the PHONE IS IN DOWNLOAD MODE, IMGUR: /c96h9k9
Make sure that You use USB 2.0 port. I had same problem with 3.0 and avoid usb hubs. You can also tap on that "cable charging" and see if it gives You options like:
Charging only
File transfer
MTP
MIDI.

Hello,
Tried with BOTH USB 2.0 and USB 3.0. Taping on the ""cable charging" does nothing.
Thanks for trying to help :good:
Have You tried doing a factory reset? Odin doesn't always do that unless You will choose a BL file. If nothing will work, don't root etc the phone, just take it to Samsung Repair Center and they will fix it within a week or two. And this way it will be 100% free. Otherwise they would charge You $200+ if it was rooted or knox was tripped.

I did a factory reset from recovery. Yes , it may be a hardware problem , but i don't understand why the phone works in DOWNLOAD MODE. Just doesn't make sense.
Here is something that worked for me.
Activate Developer options on your phone. To do this go to Settings < About phone < Build number and tap Build number 7 times quickly.
Return to Settings and scroll down to Developer options, tap it and scroll down to USB Configuration. Tap it and you will a number of options. Try taping MTP. If that does not work try long pressing it. If that does not work tap one of the other options such as Midi and then go back and tap MTP.
This should activate the ability to download files and still allow charging.
This worked for me on my Verizon S6.
Good luck.

Tried in "Developer menu" with USB debugging ON/OFF and with all the option available in the "USB configuration menu" (MTP,PTP, MIDI, etc)in "Developer menu" .
Tried also using the *#0808# code for USB SETTINGS.
Can't detect the device using a computer , showing nothing in DEVICE manager ,neither the device can't detect any PC showing only "Cable charging" without the "Connected as media device" message.
I really can't understand why it does work in ODIN - DOWNLOAD MODE.
I will try a NAND ERASE , if its still happening , obviously is hardware related.
