what's the chipset of the phone? use the app at https://www.hovatek.com/forum/thread-13054.html to verify the chipset
are you trying to officially update your phone OR are you looking for a custom rom?

[vRaj]

Chipset of the Tablet is Mt8735m according to Droid info app, but according to downloaded marshmallows firmware of my Tablet the chipset is MT6735M.
I'm looking for custom and official both rom, but few days ago I had search for firmware and I found only lollipop and marshmallows zip file but when I visit my Tablet website I saw there is showing tablet is with nougat than I visited service center and I got nougat update.
Now I don't wanna go again in service center that's why I have tried to take a nougat rom backup using wwr and sp flash tool but before backup I have format my Tablet but it's annoying to see backup is of 14.4gb and when I tried to flash boot.img for test to confirm it's working or not then I got a pop up message "invalid bbchip type (1003).
Please help me to root my device after taking working rom backup and scatter file, and I also want to custom recovery for my Tablet" iball_slide_snap 4g2.

Thanks in advance

1st error is "S_INVALID_BBCHIP_TYPE" (this error already come when I used to flash rom backup which is created by wwr and sp flash tool "readback")
2nd error is "S_TIMEOUT
Then I am going to flash complete Rom backup using sp flash tool but it's showing another error. “boundary check failed:rom_end_addr.
ROM(PRELOADER)(0x0000000000001e28b)!

Miracle backup can only be flashed using miracle box, you can flash by renaming boot.img to boot.bin then copy the image into a folder together with preloader.bin you got from the miracle box backup.

port TWRP Custom Recovery using the tool @ https://www.hovatek.com/forum/thread-21839.html or Philz Recovery @ https://www.hovatek.com/forum/thread-21495.html
For custom ROM you'll need to search online, we don't collect links to custom ROM.
