    Am getting few PMs on how to flash A75. Thought I would post it as a separate thread to avoid confusion.
    Flash files -
    Here is the link for the s/w ( a previous version of wat we downloaded.)

    Please follow this method to flash.

    Install the drivers given in the forum. (The MT65x3 folder - Install driver file). Then restart the system.
    Driver file: You can download drivers from here: or
    Run SP flash tool. Choose the scatter file (MT6573_Android_scatter.txt) and Downloading agent (MTK_AllInOne_DA.bin).
    Untick PRELOADER.

    Then run Download. ( if file not found error comes, choose each file individally DSP_BL, UBOOT etc..)

    When the s/w scans for the phone, plug in the phone(switched off).

    Flashing complete.
    Revert in case of doubts.

    Hi Rahul,

    I need your help, i have 16 gb sd card and have moved most of the application in to it and now i am facing problem while accessing the data from SD Card. Is there any way to speed it up without rooting.

    Also, I am worried about rooting this device as I have read in many places that Micromax hardware is not up to mark and there is high possibility of failure, so considering that I don't want to take a risk of rooting in it.

    Your suggestion please.

    @Abhishek, I got a copy of it from the service center. @Raju, As far as I know the first read is always slow. But after that its quite fast. Have you tried the update?
    As far as rooting is concerned; I dont think is rooting is risky if done roperly with guidance (ofcourse the bricking potential is always present :) ). And we are yet to find a way to root A75.

    yup just consider buying a better memory card ! if you want ultimate speed go for Class 10 Micro sd cards and one more thing , do not ask your local ppl selling sd cards abt the Class thing they are always clueless abt what is class in sd cards . i ordered my card from Flipkart got immediate delivery (just 2 days and if you want payment on delivery) it is not very costly anyways ...
    more over that is the only primary way also 100% guarenteed way for increasing the SD speed , after you fill up amazing amt. of data in sd card ( i think you have Class 2 sd card ) it does tend to get slow ...
    more over, rooting is not as risky as you have fear in your head, droid being a old platform now almost every result of actions are well anticipated.
    more over if exploits are found there is no worry abt rooting, the best part, even if root it just software hack and almost nothing to do with hardware ! hence no prob abt mmx hardware also being from mmx those ppl in there service centers are illiterate abt rooting thingy ! hence you can just ask them for a replacement if you brick your device in warranty .. and anyways A75 is not rooted( at-least now).

    @Rahul.. Thanks mate. FYI I have a Transcend microSDHC Class 4 memory card. With the above wise words, I will wait for the day, till we find a way to root A75.

    Consider making this Thread straight forward ...
    Its annoying to have 2 links for the same stuff ..
    + there is no need for sp-flash tool ( only ) now. ..
    it is better with the new package stuff ...
