[Device Reviews and Information] psychegr:
I spent the last night trying to figure out what is going on with this virus thing.

To my surprise my wife's Elite 1 seems a bit hard to root with KingRoot but that didn't stop me from removing the malicious software from the device.

From my research it seems that the latest OTA update S160225 comes with an application named "CallerIdSearch.apk".

This malicious application comes with the firmware update and it is present to other chinese devices.

Trying to find information, i read many useful stuff at 4PDA.ru forum using a translator. It seems that the root of all these issues is this malicious app and there only 2 ways to remove it.

One way is to root the device and use a system application uninstaller, this is what worked for me because i have successfully rooted my device with KingRoot.

The other way is to use the ADB shell and delete both the apk and the folder that contains it. This is what worked for my wife's phone which i am not able to root it yet using KingRoot.

So i am trying to write down here the steps to remove this app using the ADB shell. I read and followed those steps from the 4PDA.ru forum.

1. Connect your phone to a computer, using the CD-ROM mode and copy all the files from the newly appeared CD-ROM drive anywhere on your computer. These are the drivers which might be required later on.

2. Go to the system settings (on the phone) and press the "About Phone" near the end.

3. Click on the item "Build number." about 5 or more times and you will get a notice that the developer is enabled. Go back to main menu.

4. Find the "For Developers" menu near the end and click it.

5. Click to enable the "Enable USB Debugging" and close the menu.

6. Connect your phone to the computer again. It is now defined as a composite device and it will start installing the drivers. If at a point it says that it cant find the driver then point it to the folder that you copied the files from step one. Choose the "Unsigned Drivers" folder.

7. Download ADB from here.

8. Unpack the archive to your PC, for example, "C:\ADB".

9. Hit Win-R (run), type "cmd", and it will open the command line.

10. On the command line type "cd c:\adb" (or the path where the extracted adb).

11. Type "adb devices". At this point, the adb server will start. Type "adb devices" again. If everything goes well, you will see the serial number of your device and the word unauthorized.

12. Now unlock the phone and you will see the on-screen connection request for debugging, click "yes." Once again, type in the command line "adb devices", the screen displays the serial number of your phone and the device. Everything is fine.

13. Type "adb root". This will give temporary root access to the device without any external programs on it!

14. Type "adb shell". You now have access on your device and you need to use Linux commands.

15. On your phone, open the settings app, find "Search Service" in the list of "all", click "disable", "stop" (just in case).

16. Now at the command prompt type:

"mount -o remount,rw /system" and press Enter

"cd /system/priv-app/CallerIdSearch" and press Enter

"rm CallerIdSearch.apk" and press Enter

"cd .." and press Enter

"rmdir CallerIdSearch" and press Enter

"exit" and press Enter.

17. Disconnect the phone from the computer, hold the power button, choose to reboot.

18. Open the settings application, verify that the "Search Service" is not anywhere else.

19. In the "For Developers" menu disable debugging via USB.

That is it. A bit difficult but till now it is the only way to remove this malicious app.
