I so desparately wanted to root my new Grand Prime so I tried rooting by myself as it wasn't available by chainfire.
I haven't done much here, I just modified few files of CF-Auto-Root which was made for different device by chainfire.
Couldn't attach the file here as the size is 44MB
Download it from here: h t t p : / / d - h . s t / AWH
(remove spaces in the above link)
sad i'm not allowed to post links here yet
The zip archive contains:
Rooting method is simple.
Boot device into download mode and flash the first file: 2_cache_recovery_stock_mohan_sm-g530h.md5
Wait for the device to reboot and again boot into download mode and flash the second file: 1_cfroot_sm-g530h_mohan.tar.md5
Now after the device has finished reboot you can see SuperSU installed. Open it and it will ask to disable knox notification... Press Cancel.
If SuperSU asks for su binary update, just press the Normal button.
Hope this helps someone
Sorry guys, something went wrong while renaming the flash files. I have updated the above link which now works... Thanks...
