How to (hard or soft) unbrick Micromax A27 and Micromax A35

How to (hard or soft) unbrick Micromax A27 and Micromax A35

My friend broke his Micromax A27. He flashed a wrong ROM in Micromax A27 and I knew that opening recovery console of Micromax A27 will take much of hours (because I need to try every combination) because currently no one is successful in opening recovery console of Micromax A27. What was good, was that he made a Nandroid backup. So I was thinking how to unbrick it, I thought for 5 minutes and fixed his device. This is because of fastboot mode. Also, it was speadtrum device and I don't have much experience in speadtrum devices so it was just a challenge for me that how to unbrick Micromax A27. Firstly, it takes 20-30 seconds to boot in Fastboot mode and I always felt that this was a wrong combination (but it was correct!) and then I try another, I tried many methods and all. I installed PDANet drivers in my computer and I was lucky that I got Fastboot working with those PDANet drivers. Both Micromax A27 and Micromax A35 are the same devices (because the same chipset) and trust me, it will work on both the devices, I guarantee you this.
Finally I fixed the problem by flashing system partition via USB cable through Fastboot. Let's no more talk about my experience and move to our main piece of this article: How To (Hard or Soft) Unbrick Micromax A27 Bolt or Micromax A35.

Requirements for both the cases

  • Bricked Micromax A27/ Micromax A35 
  • a ClockWorkMod for case 1 and nothing except the downloads given here.
  • a USB cable for both the cases.
  • Fastboot for case 1 (download link given.)
  • USB Drivers, firmware, flashing tool for case 2.
  • Battery charged up to 50% (for both the cases).
  • a Brain!


Downloads
  • Fastboot: Please Click HERE
  • Nothing except your nandroid backup which you have made. 

Downloads for case 2
Note: Before or means a situation when you have a nandroid backup and after or it means a situation when you don't have a Nandroid backup.

How To Unbrick Micromax A27 or Micromax A35

Case 1
  • Open the SD Card on which you made a Nandroid backup (by open I mean connect to computer via Card reader or any other mobile.)
  • Go to Clockworkmod folder and follow to backup folder.
  • Please open the backup which you made of Micromax A27/ Micromax A35 and copy & paste system.yaffs2.img image to your folder.
  • In that folder where you extracted the system file, extract the fastboot (link given in downloads section.)
  • Now install PDANet like a normal application and when it will display phone selection then tick Others (if not sure) option.

  • Accept all the warnings and when it will complete it's work then click on minimize it (don't exit!!!)

  • Press and hold the Volume down and Power button simultaneously for 20-30 seconds.
  • When you wills see fastboot mode in the screen with red color of text then connect your USB with it. 
  • Hold Shift key and Right click on the folder in which you have extracted system image and fastboot.
  • Click on Open command window here.
  • CMD will open now, type fastboot devices.
  • If you see your device or anything in this then it means that your device is connected, if list goes blank then try again.
  • Type fastboot flash system system.img (system.img refers to the name of your system image, I wrote system.img because it is easy to type, if you haven't changed your name of the image then replace system.img with system.yaffs2.img.)

  • It will send the file and will automatically flash it..
  • When it will flash completely, then type fastboot reboot in the same command prompt window.
  • Done!!
Case 2
  • Open DPInst.exe file to install your drivers. Let it install, and close it.
  • Extract the file (firmware) and there will be .pac file which is having our firmware of Micromax A27/ Micromax A35.
  • Open the tool and select the .pac file which you just extracted.
  • Open the flasher and press Play/Start on the tool.
  • Press and hold the Volume down button for some time (5 seconds) and insert USB in your phone (and computer too.)
  • Installation of the drivers will take automatically and it will flash your system.
  • Done, now reboot!

    1. Your fastboot is working? If yes then connect ya device, make sure drivers are working and put all these files in a folder with "fastboot and adb tools" (download it from here only.)

      And then open Command Prompt on that folder and type these commands:

      fastboot flash boot boot.img
      fastboot flash system system.img
      fastboot flash userdata userdata.img
      and Micromax A250 Canvas Turbo will boot :)
