Micromax A52 (ROM Backup Generic)

Hi friends,
I recently bought Micromax A52. Thought of rooting it and after looking on xda i figured that existing root methods didn't enable root privilege in Micromax A52. Thinking of trying the manual way to root ( Creating own methods to root).
I need your help in getting basic idea of few things.
I dont know/find where i can download A52 stock OS. Pleas guide me the process of backing up stock.
After stocking original os as we can easily restore to it, would like to proceed with the rooting steps. Wondering how a rooting softy (Superoneclick or z4root etc) works based on which i will be able to give a shot on it.
I know the queries here are silly but if you help me i could learn to master ..
Thanks

Thank you sharmad247. I tried them but failed. First of all it was because of MT65xx Preloader failed driver at boot and later in Factory boot mode identified the chip is MT6575 and searched for that particular driver. (Tried rooting as well)
Got the drivers from

and installed successfully.
Now started Smart Phone Flash Tool again and configured Readback.
Disconnected phone from Data Cable.
Clicked on Read Back button on Flash Tool.
Switched off phone. Removed battery.
Connected Data Cable.
Inserted Battery.
Press and Hold on Vol - UP / Down button. (Tried both ways)
Flash tool detected the driver (showed on status bar) and popped up the error attached.
Please try and let me know when you are successful in making backup (I can understand where i went wrong), Also please share backed up rom.
If you also want to root, I tried lots of possibilities but seems i missing some steps and rooting not successful yet.
Thanks

No luck with me too
This seems to be 'Download Mode' error which our phone does not support or does not have it. But has a recovery mode with limited options.
I too tried this on Ubuntu 11.04, but no luck.

[Q] Installing ROM on MTK6575

Hello,
I'm new to flashing and installing ROM on android phones.
I enabled root in this phone.
I wanted to install JellyBean 4.2.2.
After a long search on the internet and a lot of trying I decided to open a thread here.
My phone is Star N800 MTK6575 with Android 4.0.4.
When I tried to install ROM through recovery mode it showed me this:
"Failed to verify whole-file signature"
I tried to install ClockWorkMode Recovery without success
SP flash tool and Odin also disappointed me..
Could anyone help me please?
Maybe I did something wrong, can you please explain me step by step how to upgrade this phone?
Please help me, every answer will be appreciated.
Thank you!
P.S
I think I found the problem.
When I plug in my phone in the usb, when it's turn off and without the battery, I see it in the Device Manager appearing and then disconnecting.
I tried to change the Power Settings but it didn't help. Anyone faced this problem in the past and knows how to fix it?
HELP ME PLEASE :crying:

Help with chinese 7840

Hi All,
I just got a wonderful Venue 8 7000 (7840),
problem is ONLY after double upgrading it (4.4=>5.01=>5.1) I found it's not international version, as I supposed, but is somehow tuned for china, so no google store/apps/account and lots of chinese apps I don't really need.
After searching around here, I found I should perform following steps,
please confirm if I'm right:
1) root the device using this procedure
http://forum.xda-developers.com/showpost.php?p=59203577&postcount=5
2) connect in tethered cwm and restore an original image like the one linked here
http://forum.xda-developers.com/dell-venue/general/dell-venue-8-7840-factory-fresh-t3026691
If correct, I'm having problem with both steps,
first I installed ADB drivers and rebooted tablet in fastboot mode
then I tried to follow steps at 1), but Intel Platform Flash Tool cannot write
(ps I tried both with and without externad SD inserted)
I tried also the procedure here
http://forum.xda-developers.com/and...t-temp-cwm-t2975096/post57543924#post57543924
using package IntelAndroid-FBRL-07-24-2015.7z
The adb connection seems ok, but still cannot write temporary cwm and proceed
(tried both T3 and T4)
One more thing: I can't find the option to enable USB debugging... I've searched all options under Settings
Please help !
thanks in advance
I fixed my problems following this EXTREMELY USEFUL guide for rooting and installing english rom
