How to flash stock ROM over ADB sideload After successfully rooting my phone, I mistakenly soft-bricked my phone by modifying the build.prop file. Some research tells me that the only way to repair it was to flash the stock ROM.

I have already downloaded the stock ROM. All I need to do is flash it.  

I tried flashing the ROM using SP Flash Tool, as my phone uses a Mediatek processor. However, it doesn't work. 

So now I thought of flashing over ADB sideload. So could you please tell me how is that supposed to be done?

In the command adb sideload &lt;filename&gt; whether the &lt;filename&gt; has to contain the zipped version of the stock ROM or something else.

Thanks.
I finally was able to solve this problem, as Firelord said, adb sideload wasn't able to help in the case of this ROM. And SP Flash tool turns out to be the best for MediaTek devices.  

Most of the ROMs (Stock or Custom) are available on http://www.needrom.com, so I would recommend it to others for downloading ROMS. However, the website requires signing up in order to download ROMs.

SP Flash Tool, in order to work, needs the following things:


A formatted SD Card in your Mobile Device
Battery to be re-inserted after removing (within 10-15 seconds)
Media Tek VCOM drivers to be installed in your PC. (Link: https://docs.google.com/uc?id=0B9srKhKuVIMnalFkV3EzWjVXdUE)
A scatter-based ROM for your device.



  Note: SP Flash tool needs to be Run as Administrator while using it.


A factory data reset from the Recovery mode is advisable after successful flashing.
