This is the first ever guide written by me, and I am not an expert in android and recovery, so please pardon if any mistakes are found. Lets correct if any. Also at this time Karbonn A21's system.img file is not available hence we had to perform some hard steps to get the job done.
CAUTION : WARRANTY VOID : I'm not responsible if any hard/soft damage occurs to your handset after/during using this guide. I successfully unbricked my A21 and want all of you to understand the recovery procedure properly before doing anything. Rooting your handset and applying another recovery/ROM certainly voids manufacturer's warranty. Do anything mentioned here ONLY if you understand it.
The only reason I posted this is to save any karbonn a21 users time if his device gets bricked. I had to keep my business aside for a whole day to recover my Karbonn A21 in working state.
You will have to keep handy :
1) Drivers for Karbonn A21 Click here
1) CWM by Eklovya Click here
2) AIO Flasher by Fonehacker Click here
3) Custom ROM flashable reloaded (*.zip) and A9+ system image (system.img) (because A21 's system image was not found at this time.) here and here
Also use Root_with_Restore_by_Bin4ry_v18 to root your karbonn a21 whenever necessary.
First of all you must understand that three partitions are necessary in Android : 1) Boot, 2) System, 3) Recovery
Other than these, there are Data, Cache, etc.
Unbricking an Android handset involves
1) Repairing Boot partition in fastboot mode using AIO Flasher to flash a proper boot.img file to the handset.
2) Installing proper Recovery partition in fastboot or normal mode using AIO Flasher, CWM Recovery by eklovya is a suitable solution.
3) Installing the System partition from a proper system.img file using AIO Flasher, or from a .zip file (Custom ROM) or a backed up ROM through CWM recovery.
Fastboot mode :
Fastboot mode is a Android device's state where it is possible to flash different partitions through a simple USB cable and PC. It can be activated on Karbonn A21 by keep pressed [Volume Up] key during power on (read : before power on) until your screen glows in green colour. Instantly release [Volume Up] key or your A21 may boot into recovery partition. On your PC proper drivers must be installed and fastboot.exe from Google is required to flash the partitions to the handset. AIO Flasher is a good GUI based solution for that.
Recovery :
During the above process, (for Karbonn A21) if you keep the [Volume Up] key pressed until the screen glows red, and then release the key, you enter into recovery mode. Updates to operating system's files can be installed from this mode. Stock recovery means manufacturer provided Recovery partition 'as it is' and Custom recovery is recovery partition OS developed by other developers, CWM recovery being the most popular one.
STEPS FOR UNBRICKING :
1) Repair Boot partition
Firstly enter into fastboot mode, and then use AIO Flasher to flash boot.img of Karbonn A9+ / Cherry Mobile flare to boot partition of your A21
2) Repair Recovery partition
Using AIO flasher, flash CWM Recovery's img file to recovery partition, in A21's fastboot mode. (For more info read this and this thread)
3) Install System.img to system partition
Currently A21's system.img is not available, else we could easily flash it to A21's system partition and get our handset running. Hence I flashed A9+ system.img downloaded from above (note that the downloaded file has extension .7z, to be renamed to .img), by AIO Flasher to system partition in fastboot mode. The flashed system rom was made for Karbonn A9+ hence it didn't work on my handset properly. I got white display and the touch screen and buttons didn't work. I used AIO flasher's screenshot facility to get into the handset and found that actually the system was up and running properly, except the display and touch interface. Then I decided to flash custom ROM and tried using santo_rock 's custom ROM DarkBoid. But it didn't work. Then I flashed ashoknraj 's custom ROM Flashable reloaded. It was success.
4) Install ROM for A21
To install the custom ROM via Eklovya's CWM recovery, the .zip file needed to be inside internal memory in the form of update.zip file stored in root folder, but the internal memory was not accessible through my PC as its usb drive was shown in windows explorer but was in [no disk] state, and I could not select [Turn on USB Storage] on my A21.
Here comes ADB 's power. I used ADB push to push the custom ROM into the internal memory.
Use the following command to push the update.zip (rename the custom ROM to update.zip) :
adb push update.zip /mnt/sdcard/sd_card/update.zip
Note the spaces and special characters properly.
The file is greater than 100 MB and hence some time will be required to transfer that file into memory.
If it shows error Permission denied, then remount using the command
ADB REMOUNT
and then try again.
Now we have the custom ROM ready in A21's internal memory, lets flash it. Boot into CWM recovery mode and select apply update.zip, let it install, and then wipe data/cache and reboot the device normally. (For more info read this thread)
If everything goes well, your A21 will now be successfully unbricked.
Of course you need patience and concentration to do all this.
DISCLAIMER : The above process and softwares are not my creation and are of respective developers. I just aggregated all these to one place.
Thanks for the guide. Do you know of any solution if phone only boots in QPST Download mode? No other methods like Fastboot, adb working for now.
I've connected via QPST tool but don't have images to flash. If you can research on it and provide the files to me, it would be great help.
Enter QPST download for karbonn A21
Is there any soution to this problem. It arises when I install cwm. But I have restored the default recovery by mounting it in linux.
When it shows this in sceen you can access all the partitions in linux.
I used this command to restore the default recovery as it was 16th partition that I changed with cwm image
dd if=/home/tushar/recovery.img of=/dev/sdc16 bs=4096
Also fastboot mode in not working on karbonn A21. powering up while holding up volume key shows me no green screen
karbonn a21 brickked
need help
need ashoknraj 's custom ROM Flashable reloaded

Karbonn a21 Bricked. please help!
I tried installing Nokia X firmware on my Karbonn a21 but it gor stuck at black screen no boot logo or animation.
When i press volumeUP+ power itwas going to black screen only so i thought recovery partition is also gone
But volumeDOWN +power was working so i put it into QPST mode and tried EMMC download software with Karbonn a9+ bp firmware. it resulted in error of cookies not present!.
Then i got to know that volume up button was broken from hardware only. so i got it fixed.
Now i see green light for fastboot and then pink for recovery.
BUT if i leave power button on pink(recovery) it goes to black screen
And if i leaveit on fastboot(green) it stays green only .
I dont know if that failed QPST try blew my recovery or it got bad in the beginning only!
QPST mode is still working and drivers are getting detected as Qualcomm USb 9006.
Please tell me what i can do to revive my phone!. (Its not in warranty)

How to restore the Stock ROM:
For Grand X ProOK, today I'll be showing you how to restore the Grand X Pro back to Stock, just as it was before you flashed the custom ROM...
You will need:
A PC Running Windows 7 (ONLY WIN 7 WORKS FOR NOW)
The Grand X Pro
A USB Android Cable
My FlashTool
ZTE VCOM Preloader Drivers MT6577
So , first get the full flashtool from here: ApeelMe's Blogspot - ZTE Grand X Pro FlashTool
Also install the Preloader drivers if you didn't do so...
Plug in the Grand X Pro and then turn it off...
It should (on the PC) install some drivers and fail , don't worry...
Open flashtool and select the NandUtil file and the Scatter file (nandutil.bin and mt6577_scatter.txt , their names are like that)
In the menu where you can select ANDROID , RECOVERY , BOOT , MBR, DSP , Preloader , etc DON'T Touch anything as it will wipe that partition and you may hard-brick your device..
Click "Download" in flashtool, wait till the green circle...
After the green circle appears , close flashtool and disconnect the phone.
Now turn it on, good ol' stock ROM...
Hope this works for you as it did work for me...
TeamMaverick
it didn't work for me, it completes the download and evrything but it still just stands on zte sign an that is it, can you help?
trying to use but i get a nandutil.bin file is not a valid da format. Is it corrupted?
Anyhowse. i went ahead and flshed with all in one. im now with cyanogenmod and cwm which is the opposite of what i needed. How can I return to stock rom and stock recovery? basically i need to send it back to shop because of faulty screen.
Resolved. Followed guide with link here

2. select File-open scatter loading file
3. select MT6577_Android_scatter_emmc.txt from restore to stock folder.
the ebr1 etc should be automatically filled in with file pathway
4.click download button
5. plug in switched off telephone (if drivers installed properly should just run)
6. wait until green circle appears. hey presto! switch on telephone.
nothing i hav done all that, an the problem is when it is all finished, i get errors such as can't mount data, it doesn find anything, i don't know what to do else, if you want i can post pictures when i enter recovery mode

Hey Buddy!! Sometimes it gonna happen if you keep tring to mess with your phone...
Just one method left!! That is to flash stock rom using Flashtools on your Windows PC!!!
#gOtm
hi
how are you
I have a big problem
When you update a device error occurred ( fastboot failde)
Then the machine continues to this situation
Video demonstrates the problem
youtube.com/watch?v=E8k0KOQF8p0&feature=youtu.be
I do not know how to solve the problem
is there a solution?
you tried to flash a kitkat rom over an existing lollipop and the files flashed cannot be loaded by the lollipop bios (that one remained the same) you need to flash a lollipop stock rom instead
1. download and extract this file someplace on your pc
2. uninstall your existing Phone Flash Tool and from the drivers folder install both files (Intel Phone Flash Tool and Android Driver accepting defaults) reboot pc when finished
3. place your tab in DNX mode (from power off press and hold both volume keys then press pwr to start, in a few you screen will show "Fastboot starting..." message and hang on that. you must get that message on your tab screen, restart from power off until you have it)
4. start the installed Phone Flash Tool and load flash.xml from the extracted YT2-830L... folder then Start Flashing, it will reboot when done
