I mistakenly uninstalled my Download Manager 4.4.4 in my Samsung Galaxy Grand prime G530H. A system application. I tried replacing it with a Download Manager 2.3.5. I did that by using a file explorer to place the 2.3.5 in the system folder. Then I rebooted the phone. It didn't work. The phone doesn't recognize the 2.3.5. Looking through the file explorer I can see the Download Manager 2.3.5 is still in the system/app folder and I tried deleting it but it won't delete. I need help on how to get the original Download Manager 4.4.4.

  • Can you just push a custom ROM to your phone and be done with it?

  • Custom ROMs are like different OS. They are based off of android (as android is open source). You don't need Michael Nancarrow to send you a ROM, you can search one up (perhaps cyanogenmod for it's fame), find build, and flash. But that might not be necessary

Refer to MANI's answer regarding resetting the device, this may assist you, but as far as I am aware a reset does not touch where the applications are actually stored.

What is a ROM?

Read Only Memory. Essentially just a new firmware/software for your Android Phone. For a more detailed explanation and information on a ROM look on this website. If unsure if you should do this process, read on How To Geek about the "Top 5 Reasons to install a Custom ROM"

Process for your Phone

Here is an example of how to install a custom ROM on your phone (including Drivers, links to ROM etc.)

Here is the Xda Forum for your phone. Covers troubleshooting, ROMS etc. I would suggest you look here also.

Other Resources

Refer to this question on SE that provides a detailed answer (thanks @Izzy)

Hope this helps you. Undoubtedly a Factory Reset could assist, but I am not 100%. The steps for a Factory Reset on your device are located here.



  • Thank you Mani. Mike. I just signed up at the xda forum. I have requested for help. Just hope someone can help
