Having Problem in Unbricking Lava Iris 504q

Hello Guys,
My lava 504q was bricked so i was using above method for unbricking it step by step, but got following error after connecting the phone,

"Image PRELOADER checksum failed!Checksum reference value(0x2f771) in the config ini file.
please re-fill correct checksum values in checksum.INI under tool folder and re-load scatter file again!"

Same error also include Image like UBOOT, BOOTIMG,Recovery, LOGO, ANDROID, CACHE, USRDATA and FAT

I used unbricking method on Windows 7 and Windows 8.1 desktop.

Right now i am in deep trouble and you guys are my last hope.
So please please help me.
Thanks in advance

Dear Shailesh,
Thanks for helping me out. I did what you have suggested but having same problem.

May be sp tool is not detecting my phone as after clicking firmware update same error pop up even though I didn't connect my phone or may be I am missing something?

I bricked my phone when I was restoring NAND back but after restoring it phone did not boot up.

And if phone still going in recovery then just flash a fresh rom instead of firmware Flash..

The problem is I am not able to open in recovery mode through phone.

As you said I will download different version of ROM and try it. Let's hope it works.

Glad I saw this post. Had got my phone bricked due to an incompatible ROM and this thing recovered it and saved it. Great work. Keep it up.
Can you please edit one thing in the post that you need a PC with admin rights, coz I tried it first on my office PC and it didn't succeed, then I realized that perhaps the VCOM drivers can't be installed without admin rights. I tried it on my laptop and it worked like a charm.

By the way, have you heard about the prototyping board UDOO? It's great for android and electronics learners.
