Win hasher gives these hashes of extrcted system.img file from system.img.7z withSHA-512 Algo.
 
I am also getting the exact SHA-512 checksum as 'akhil A75' is getting.

@ninadchaudhari
Probably you have calculated for a wrong file?.

The solution is to use a static IP for your WiFi connection, to do this:
From your android device, goto Settings > Wireless and networks > WiFi Settings > Click menu button (left) and select advanced.
You'll see an option "use static IP" under IP settings section. Enable it and enter the following parameters.
IP address : 192.168.1.253
Gateway: 192.168.1.1
Netmask: 255.255.255.0
Dns1: 8.8.4.4
Dns2 : 8.8.8.8

By doing this, you should immediately get connected to your wifi network. I've tested this with my BSNL Teracom Wifi modem.

Umm that's strange :)
it may mean that the device (phone) is using a similar encryption as ur router is providing ( as even a simple turn off and restart also fail ) a solution is sure needed...

more over many anrticals over internet provide some explanations which i do not think apply in this case
but it is strange y even Static IP works for u as many ppl have reported success after Static IP ...
Fine , Will reopen the project as i get time.

Extract The Drivers to Desktop & Plug in you Micromax 75 via usb cable
Put your phone in Debugging Mode.

Press WindowKey + R (Together)
Run will pop-up, type in
devmgmt.msc
This should open Device manager
Look for "Android Mobile Phone" or "MTK 6573"
mouse right click & select Update driver software
Choose Browse my computer for driver software
Choose Let me pick from a list of device driver on my computer
if you see list, simply press next otherwise
click on Have Disk...
Browse to driver folder & win7 folder pick -> usb2ser_Win7
select first in the list, press next.
Drivers Installed.
Start SP tool, select MT6573_Android_scatter
Reboot your micromax (don't power off)
after 20 sec click download on sp tool to begin flashing.

@vaidyasr
Dont change WiFi router settings
just configure your device with static ip addr.
if you dont know how to. just tell me your Router's ip address.
 
@ever win the Static Ip thread is already created.
Request you to direct to that thread and do provide help...
thanks for providing support though :)
 
@all
can anyone of you upload an almost empty update.zip ?
Just keep the META-INF folder in the update.zip .

@ karan do u mean by Recovery then
let me make it more clear as most ppl won't get it here:p
just download the attached zip and place it in the sd card rename it to update.zip
then enter recovery by holding the power button and vol + button
( after u switch off ur phone )

similarly try other zip

note : first one is signed
second one is not

I am having issues with hash values.

Though the SHA512 value is matching, but I am getting the following value for Whirlpool ? Is
it wrong ?

Thanks a lot ninadchaudhari for your efforts.
 
@svkroy yup it is wrong , b4 i mistakenly posted the check sums of ROOT 3 images which i promptly corrected as soon as it was released :) that time i just updated the SHA512 not whirlpool in hurry as most of users here are Windows and they did not find the whirlpool checksum
now updated :)

Really sorry for the inconvenience caused
