Ergo B501 firmware cleaning from viruses

  • Run ROMHelper and go to the ROM Fix section. Enter the path to system.img and click the Select Package button.
  • Waiting for the application to unzip the image may take a few minutes

ROMHelper-Extract-Firmware

    • In the application list window, selectDeskClock.apk , which downloads the malicious modules into folder MakeupOutedaROMHelper-delete-APK
  • Next on the left we select Explorer , find the folder /system/priv-app/MakeupOuteda and delete it

ROMHelper-modify-firmwareThen click Build. The original firmware will be saved with the suffix _old.

Important! The program will try to sew it’s own advertising!

To prevent it from doing so, delete the C:\Users\% username%\AppData\Roaming\YZMG\RomZhuShouSV\Cloud folder before clicking Build.

However, if you frequently use the program, it is not convenient to manually delete each time. In this case, the folder reading ban will help:

Also disable the System , Administrators , and Administrator groups.

The deny.bat script from the archive will do this automatically. Run it as Administrator
