Not recommended now .... See other ways in the Sticky !


As you know this phone cannot be rooted by current popular common exploits
After a lot of work with almost 5 zips, more than 1Gb of bandwidth and countless hours, finally the phone is rooted


You can just download the ROOT4.7z A75-ROOT.7z from here:
EDIT : Updated...

Presenting A75-ROOT.7z for root A75


-- This is Mandatory Check the extracted system.img for checksum with HASH TAB

for
SHA512 :

Whirlpool:

1. -- Now replace this system.img with the one from the update package.
2. -- Follow the exact way you flash your device from the new update
3. -- Restart your device
4. ---
   
   Updated : No need of wifi and other stuff now !
   

• -- Voila , you are ROOTED !

Titanium???

Ankysoni

hey now tell me what are the benefits of rooting

ninadchaudhari

Yup everything is working awesome
I had many fixes for it !
Just download and ya after u restart ur phone do not forget to install Busybox as your favroute Titanium backup requires it
also you will face slow backups and restore timings as the app and binary i have installed are stable versions so just update the superuser app from Market


Hope that helps

erandevishal

hi ninad.
i got whats rooting.
pls will u tell the whole procedure right from the begining,with all required softwares and all.
i have done nothing yet to my phone.
thanks

ninadchaudhari

A video tutorial is in the progress for complete n00bs ,
I will soon uploading a package with all the stuff necessary ...
you can refer the thread for flashing in the same forum..

EverWin

Hi,
@ninadchaudhari
thankyou for your hard efforts, i was able to flash new system.img but to download busybox i was unable to connect my currrent WiFi.

tried flashing again with no luck then i have flashed back to original New System.img and WiFi works now.

i am able to enable & insert WiFi password, it stuck afterwards with the message Obtaining ip address.

Hope you will fix this too soon.

Thanking You

ninadchaudhari

@everwin , i do not think that might be a problem ...
as library files have not been touched by me !
there may be some different kind of local problem
1.) report if you already have flashed the new update from mmx ?
2.) try installing Cachemate from market and try clearing the cache
3.) some times a simple restart ( twice) helps
4.) it might be some problem with ur router try restarting the router
5.) try deleting the wifi and connecting again

As it has to be noted that in a ROM installation if wifi bugs are present , the wifi does not start up ... it displays "Error" message, more over the wpa supplicant is also not touched by me..
you can try the above options and i am sure the problem wil be solved ..

Tresezk

SHA 512 and Whirlpool .Do you work for the military ,DOD !! .SHA 256 is more than enough .(I dont trust Md5 though .Curse you google)

Second thing
For busybox
JRummy's one is better than Stericson (preference )
Busybox

EverWin

1.) yes done that & WiFi works
Flashed your system.img again
2.) Installed Cachemate
3.) rooting twice done
4.) nup WiFi working Fine on other devices
5.) Done several times. also, tried Open Shared without any luck.

None of the above worked
I have to flash system.img only or else just like new mmx update?

MeanWhile: in WiFi setting, under Advanced, configured Static IP & it fixed the WiFi problem
can't obtain ip address from DHCP server

Till then enjoying Optimus one

ninadchaudhari

@ karan
Thanks i am replacing the link with JRummy's Busybox
I just saw the number of comments

Thanks !

More over I just thought If All of us can use SHA512 also just few seconds are required then y not go for it

kumar abhishek

+1 same problem with me

ninadchaudhari

@ abhishek I think simple reboot should have solved the problem but as even u are facing it let me go in deep now !
jus try simple reboot though i will start fixing that bug.
more over the everwin confirmed abt wifi correction if he has fixed wifi ip

TRY THESE THINGS
after applying rooted zip


TRY a factorty reset......
also the BEST FIX : use static ip address it is no harm in it

as if there is a problem in the ROM usually you see Error in starting up wifi
refer

akhil A75

Please ninad post a video how to root A75

ninadchaudhari

video coming soon ...
the problem is that i do not actually own a A75
I have requested a member to do it for u guys though

ninadchaudhari

@every one
plz try factory reset , and use static Ip for solving problem

kumar abhishek

I cant do factory reset because I uninstalled default launcher and wt do u mean by static ip?

ninadchaudhari

No problem just go to titanium backup and convert ur default launcher to system app ! then even if u do a factory reset that launcher will not be lost and ya one more thing remember never ever remove any launcher from the system
at-least keep any launcher (any one u love) will do but keep one in system

2.) when u go to advanced options you will see manual entry of wifi details
just add something like IP: 192.168.1.64
subse :255:255:255:0
note these are just the most general settings they may var according to ur installation if u need help do contact me via a pm.

akhil A75

akhil A75

ninad plz help me out!!!!!!!!!!!!!!!!!!!!!!!

545himanshu

I am also getting the exact SHA-512 checksum as 'akhil A75' is getting.

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

wi-fi is not working after the flash. After enter the pin for my access point, it says 'Obtaining IP adderss from ...' and stalls there. Even with the static IP, the wi-fi not working.

ninadchaudhari

@vaidasr

Go here for wifi : Set up Static IP

545himanshu

and i don't know why when i install drivers and plug in phone(switch off) it shows battery charging i am using win7(32BIT) i have installed driver lots of time..........

vaidyasr

The router logs show below: So the wi-fi is connecting and disconnecting immediately.

The below message is keep on repeating...

[INFO] Tue Feb 21 08:42:46 2012 xxxxxx: Wireless system with MAC address xxxxxxxxxx disconnected for reason: Received Deauthentication
[INFO] Tue Feb 21 08:42:15 2012 xxxxxx: Wireless system with MAC address xxxxxxxxxx secured and linked
[INFO] Tue Feb 21 08:42:15 2012 xxxxxx: Wireless system with MAC address xxxxxxxxxx associated

ninadchaudhari

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.

EverWin

@545himanshu
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.

ninadchaudhari

@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

545himanshu

@everwin

i do exact what you tell me but driver can't install

Tresezk

@all
can anyone of you upload an almost empty update.zip ?
Just keep the META-INF folder in the update.zip .

ninadchaudhari

@ karan do u mean by Recovery then
let me make it more clear as most ppl won't get it here
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

Attached Files

	update.zip (1.7 KB, 33 views)
	update2.zip (276 Bytes, 19 views)

545himanshu

micromax does'nt provided me any zip folder can you please upload android scatter file

ninadchaudhari

install drivers b4 connecting the device

How to flash your A75

svkroy

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 ?

@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

ninadchaudhari

I have updated the hash calculating software HashTab tool to quickly find file hash information
this one is the awesomest software !

ninadchaudhari

For Wifi just download the "ROM Manager" free from market

Click on Fix permissions
-- run the script i will be giving
+ ROOT5 is coming soon
