[Micromax Canvas Nitro A310/A311] android.crux:
Now, i have seen countless cases of people being not able to flash their MMX A311, as for me I was having the same problem too, turns out that the driver is the main problem.

I was trying out YGDP but i was stuck at "Enabling Download Mode"

and while trying out SP tools i was getting an error "s_brom_cmd_jump_da_fail (0x7f3) " .

Then again, I tried many things, and got my phone working in 10 minutes. :good:

So if u too are stuck, then try my method. :D

It is highly recommended you do this in Windows 7.

I did everything while my phone was switched off but battery was inserted.

Disconnect your PC from internet just to be double careful about the flashing.

First getting the proper driver:

Now, before installing the driver, make sure that you dont have any other driver installed rather than the one which i will provide, if you think you might have installed some other driver then try removing it by "usdreview" (but it didn't work for me though that's why PLEASE TRY THIS ON ANOTHER COMPUTER OR LAPTOP, MAYBE IF YOU HAVE ANOTHER LAPTOP OR COMPUTER OR MAYBE TRY IT ON YOUR FRIEND'S SYSTEM. THIS SOLVED THE "ENABLING DOWNLOAD MODE" PROBLEM FOR ME)

Download this driver, I did with this one:

Extract it and remember where the folder has been extracted to, as it will be needed to install the driver.

Installing the driver:

Open up Device Manager.

right click on My Computer > Manage > on the side pane click on "Device Manager"

Keep it open.

Now first CHOOSE A SINGLE USB PORT WHICH WILL BE USED BY YOU THROUGHOUT THIS WHOLE PROCESS. DON'T CHANGE IT!

Now use your usb data cable and insert it into your chosen USB port and then to your phone.

As you will insert it you will see a device popup in 'Other Devices' or some other tab named as "MTK65xx Preloader" or something similar like that.

NOW BE QUICK IT DISAPPEARS IN 3-4 SECONDS !!

Quickly right click on mtk65xx preloader and select "Update Driver Software"

Now as in the new window opened up, select " Browse my own computer to install the driver"

Browse to the DOWNLOADED DRIVER'S folder, select the folder "Win7" for Windows 7 and Above.

Now the driver will be installed.

Now after being installed, take out your phone from the usb cable, dont remove the usb cable from the computer because you make mistake while again inserting it back into to a different port.

Getting the stock rom and YGDP tool:

Now get the stock rom for A311 and YGDP tool from any verified site.

I downloaded mine from :

Download from this site needs user to be logged in, it barely took 2 mins for me to register and download it.

If you have any other site you trust then go on and download it from there, but I recommmend you to follow my steps and sites as I did everything and succeeded.

Download the ROM and also the YGDP tool.

Extract the downloaded file to some specific folder as this is the ROM and the tool required.

Installing and Using the YGDP tool:

I have seen people recommending latest YGDP tool but on the contrary I recommend the downloaded old version from the previous step, it worked for me like a charm!!

Install the YGDP tool from the extracted folder.

After installation, YGDP desktop icon will appear, open it.

put the password as: 369

Now, on the top pane, press the button "Config"

In the window opened, on the side pane, carefully select "8297W" for A311

And after selecting that, on the left side section,

in the " Please select CPB file : " , click on the button beside it and browse for your

extracted folder of ROM and select it

!

now it click " Apply " button .

It will take 1-2 minutes, and after this you will be brought back to the main window!

Now click on " Start "

And wait till in the bottom message log it says " ENABLING DOWNLOAD MODE" , now follow the next step !!

Flashing your phone:

As YGDP stays in enabling download mode, now insert your phone back to the usb cable which was left out in the computer.

Now, if you did everything correctly, YOUR PHONE WILL BE DETECTED and YGDP will start flashing by itself, wait till it says 100% with a green bar.

Remove your phone from the USB cable and then click "STOP" in the main window of the YGDP tool.

Power on your phone.

Your phone will be successfully be flashed and alive !!! :fingers-crossed:

FROM NOW ON, ALWAYS MAKE A BACKUP . :silly:

Feel free to ask questions. :laugh:

If u have suggestions, I'm open for it!! :laugh:
