[Completed] [Q] How to fix Boot Loop ?

Hello Everyone, I am a Noob in Flashing Custom ROM...
I use Micromax Canvas A63 (Rooted)
I successfully Flashed Xperia Custom ROM in my Phone, But after Flashing it, My phone could'nt detect my SIM. There is no problem in my SIM card as i had used it on another mobile phone and it was working...
The major problem starts Now: -
After that, I Restored the Backup of the STOCK ROM and rebooted my device (in hope to reverse all the things back).. But after that it got stucked in Boot Loop and is not starting beyond that Xperia Animation.
I Tried lots of Methods like- WIpe Dalvik Cache, Format/Cache, Format Data etc.. but still it is stucked in boot loop..
PLEASE SOMEBODY TELL ME THE HOW TO CORRECT IT

From what you've explained, seems your phone is running on stock recovery and not custom, that would explain the installation aborted error, else, you're flashing files either in the wrong format or improperly downloaded/copied
The solution is to flash the system.img from stock backup and your phone will be back up.
I need you to clear something up. you said
"I TRIED TO INSTALL STOCK ROM BY Brcm_MultiDownloader_1450 SOFTWARE AND I FLASHED D ROM.....BUT AGAIN THE PROBLEM STILL OCCURS!!! STUCK AT BOOT LOGO!"
How exactly did you flash it?

if you flashed the stock ROM and flashing was successful, its only logical to say your phone should be in good condition now. am I missing something?

dude samething happened to me if its because of chainfire then do the following take ur battery out and at the time u insert go to recovery mode micromax recover - power+volume down then from there go to choose a install new zip that is it can be restored only if u have a backup or else try finding a image in google and this must work and if u dont have backup and only idea i can share is clear cache go to advanced clear dalvik cache and reboot ua phone and again take off battery while booting and restart :good:
all the best
Chainfire 3D only support Gingerbread or lower. Not for ics+, try to wipe cache and dalvik,if problem still exists, reflash ur rom

Don't worry my friend one and only one solution just flash the stock ROM with flashing tools. You can search in XDA thread regarding this....
Else download the latest from this link
http://xdafirmware.com/micromax-a117
For flashing instructions follow this link-
http://androidxda.com/flash-stock-rom-using-smart-phone-flash-tool
not able to install other ROM s in a117
Sir I installed xld ROM 1.3 first time ,it booted successfully but it lacks sim toolkit (sim not supporting) ,whenever I try to install any other ROM it sticks to the boot image (bootloop) but at the same time xld ROM is easily installed

So pls guide me a solution

i dont have your device, but the solutions for this situation are pretty limited. im kinda suprised putting the correct rom back on didnt fix it.
i believe your best move (maybe only move) would be to flash the factory files back on.
if you dont have them, or dont know how to use them try searching google like this "Micromax unite 3 q372 return to stock" or "Micromax unite 3 q372 stock firmware".
do a factory reset. worked for me
Dude, Unite 2 and Unite 3 has different Mount points. Your device might be in soft brick. Only way to get back is flashing the stock firmware. I think restoring nandroid won't help , still you can try
