i am unabel to understand that why it is coming pls help pls pls pls pls
Which recovery you using
for signature problem try clockworkmod recovery (try there option disable sign)
or download file again may be it is incomplete or sign missing
Are you sure you have a recovery image installed other than the stock one?
Try 1click root & recovery script from maverixx.
It`s very useful for for rooting and reflashing recovery, and You will see if there is any error.
1. Download RootTattoo1Click_Recovery_2010-03-18_Mvx.zip from http://forum.xda-developers.com/showpost.php?p=5835675&postcount=1
2. Extract rtattoo folder to C:/
3. Run rootTattoo.bat or RecoveryTattoo.bat
If necessary Copy other recovery file to C:/rtattoo/sdcard and run RecoveryTattoo.bat again.
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)

Any backup before system app uninstall? If you have one then restore that.
If not then download stock ROM from here & AIO Flasher from here & flash stock rom, then root it again & before playing with system apps take backup....
help about karbonn a21 reinstall
I have a friend who has completely wiped his Karbonn A21's data out, trying to show off his rooting skills. He had successfully rooted his phone, but then he tried to change the icons of the OS using an app called Rom Toolkit Pro, but then his device displayed an error, and since then all apps he tried to run started crashing. He turned his device off, but when he started to turn it on again, it just kept on displaying the boot animation, but never actually booted. He thought he had bricked the phone, and followed some vague instructions online on how to unbrick; and then he ended up wiping his Karbonn A21's internal storage, completely wiping the Android OS's files off. Now his phone is completely dead.
Is there any way an Android OS can be freshly installed on his phone? Due to the rooting, his warranty is also no longer valid. Or should he take his device to the service centre? Please help guys

So mobile hang at boot animation, not a big problem..
Install drivers(XP preferred) & power on your mobile & connect it.
Run AIO flasher & use it to reboot your mobile into fastboot mode & then flash system & recovery image.
Restart from fastboot & have fun...

qpst download mode will appear when you press "vol down & Power Button" same time.. To boot in to fastboot mode press "vol up & power" buttons at same time & leave vol button soon you saw green screen...
Or as told before connect mobile to PC when its hang at boot animation & run AIO & find "reboot menu" & select "fastboot mode", press reboot...
If after restart command, mobile going to QPST mode then you need different & more complicated method :fingers-crossed:...

fastboot mode is "green screen mode", as soon as you saw green screen leave vol & power buttons. Download AP firmware from here. Drivers included.
Either use Qualfast method to flash Stock ROM or AIO flasher... steps already explained there so read those....

Both methods will work & when you connect your mobile with PC it will ask for drivers. Chose location of driver files & system will do the rest...
Driver installation is very basic step, be careful with advanced flashing methods..

Dear all,
I ll try to explain my problem :
I have a wiko rainbow
I installed a recovery from android 4.2 to change my ROM
unfortunately, it doesent work correctly ..... now I just have access to my recovery
I d like to change this recovery (to try to install again the ROM from this new recovery)
my problem is : I know how to install a *.zip (ROM format file) from my current recovery, but what I d like is to install/flash a new recovery, so a *.img file
So, is it possible to install/flash this *.img (and so change my recovery) and how can I do that ?
Thanks in advance for your answer, proposition of test (I can nomore use my phone )
Download the stock ROM for your phone, download your preferred custom recovery(CWM/TWRP/PHILZ), download SP flash tool and the mtk drivers. After installing the drivers, unzip the Stock ROM zip and replace the stock recovery file with the custom one(the name must be recovery.img)make sure you don't put it into a separate folder. Run SP flash tool as administrator, select scatter loading, browse to your ROM's scatter file, uncheck all the options except recovery and download, then connect your switched off phone via USB cable. Wait for the download to finish, unplug, boot into recovery and do a factory reset.
Hit thanks of this post helps.

Hello!, I hope is not late for the help. Follow my steeps (sorry for my eglish)
1. Download the firmware for ur mobile (U can do it with a program called Frija, is the fastest way).
2. Download ODIN V. 3.10.7 (Is the best version for your model)
3. Open ODIN and put the ROM, select the option: Nand Erase All.
4. Flash!
5. If all goes fine congrats, but if ur phone is stuck in SAMSUNG logo go to step 6.
6. Put ur phone in ODIN mode again, and re flash but don't select Nand Erase this time.
7. Wait for 100% then, turno off ur phone, and enter recovery mode (VolUp + Home + Power)
8. Select in recovery: Wipe data factory and Wipe Cache Partition.
9. Restart ur Phone and wait. If all goes fine: Congrats.
i support what "cc33wm" wrote,
also, at least on mine i had to unlock the bootloader first in order to root it properly(i also installed twrp recovery), so it might also be your case
