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

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.

Hi
Sorry for poor English
I'm Re-partition my phone (D802) with this method in TWRP (with gdisk) :
https://forum.xda-developers.com/lg-g2/general/guide-resizing-lg-g2-partition-size-t3143580
Thats worked ....
After all the stuff was done
i'm flashing custom rom (AOSPExtended) and GAPPS and reboot phone to boot up new rom
unfortunately didn't boot anything .... Only LG logo appeared
I did not have access to the recovery (TWRP) completely (even hardware keys method do nothing - for bring me back into TWRP)
I didn't know what to do
so, I tried to install Stock Rom (with LGFlashTool v1.8 and TOT File)
Then I got this error:
[15:23: 1] ## [ERROR] : Partition Change system Partition[15:23: 1] ERROR: system Partition was Changed.
[15:23: 1] LAF retrieveGPT() failed.
then, I tried to install Stock Rom (with LG Flash Tool 2014 and KDZ(Android 5.0.2) File)
It was successfully installed
but didn't boot and Notification light blinks (even after 20 minutes)
What should I do?
no custom recovery (any method to install TWRP with this condition)
no fastboot (any method for boot into fastboot - Vol+ and Power button or Vol+ and plug usb don't worked - I tested everything)
i can only enter to Download Mode
Is there a software method?
Or only the hardware method can solve it? (please tell me if hardware method can solve it)
p.s. : i replace eMMC on this phone in repair shop before but i don't have any problem with that till now

It says the stock firmware is for nougat, i myself am currently running marshmallow. I had tried to flash nougat through the custom recovery, ( when the thing was stuck in a bootloop) and it said something like only versions upto *some serial no.* can be updated.
Anyway, thanks for the links, will try it.:good:
Hello, I own the ZE552KL (Z012), but when I saw your question I was able to find a link containing what you need for your model. Take a look, I did not download but I believe it contains the necessary files.
1) download firmware files :
https://tinyurl.com/y863uw7y
-save UL-ASUS_Z017D_1-WW-13.16.5.33-user.zip to SD card / insert card in phone.
- under the folder ''boot recovr z017dww13.16.5.33''
2) Go to fastboot mode (power + vol up)
- flash recovery.img (command: fastboot flash recovery recovery.img)
- flash boot.img (command: fastboot flash boot boot.img)
3) reboot to recovery (power + vol down)
4) install update form micro sd card. set the file UL-ASUS_Z017D_1-WW-13.16.5.33-user.zip that you saved earlier
5) wipe cache
6) factory reset

I hope you can solve your problem.
Though I have some experience with rooting phones and flashing custom rooms, I still consider myself to be no more than a novice in this subject. I have a LG K20 PLUS, metro pcs, and I have it rooted running PBRP recovery and the unofficial lineage 14.1 rom. I have been trying different roms and just recently kernels. I was trying to get kali nethunter working and on here at xda two files that I could flash to install it. I will have to go and look to get the names right but one was something like kali nethunter generic rolling something and the other was a custom kernel to complement it. Both flashed without any errors. When I rebooted, after the LG logo I found myself with a kernel panic error.
Kernel crash!

I am still able to enter revory mode and through recovery boot to bootloader. I had attempted reflashing the recovery to TWRP, which was successfull, but attempting reflashing kernels (though flashing without errors) has had no effect on the kernel panic issue. I have reflashed roms as well, it seems nothing that I know how to do will fix the problem. Surfing the web for answers... has only shined light on just how little I understand a lot of this stuff. Most information ℹ have been able to find (in a lot of cases I don't even know if it applies to my specific problem) is way beyond my technical ability to comprehend. I hope that someone here can guide me through this panic and help get my K20 plus functional again. :fingers-crossed:
You're gonna need a PC with LG Windows USB drivers, LG UP v1.14, as well as LG Uppercut 1.0 which is a modified version of LG UP, and a stock .kdz image to reflash your phone back to stock. You can find those links on this forums or other LG phones threads. I'm pressed for time so I can't link them all. I've had a similar issue with kernel panic where flashing any ROM or kernel couldn't fix the issue. The only thing I could do was flash a stock image so that the partitions could be overwritten and corrected. You can find the LG stock image here https://lg-firmwares.com/lg-mp260-firmwares/#tab=firmwares I suggest an older variant like 10j or 10v, though I've had success installing 11k and reverting to 10j but I'm not certain if the newer images have any code that makes it more difficult to modify bootloaders or revert to older stock versions. MTP is your ideal image. MTD is a Metro Demo and MTK are FRU (field replaceable unit) images with some capability of having special resizable partitions but that goes beyond my understanding and scope of this post.
There's a chance you'll find Download mode on your phone doesn't stick to more than 20 seconds or so, which isn't enough to flash an image without issues. I found the fix for this was to go into recovery and wipe everything you're allowed to wipe, recovery will caution there is no operating system installed. That's fine. Rebooting to system should lead to a similar warning on boot. Custom Recovery should still work but you won't need it. You'll need to get back to download mode, plug the phone to the computer, and be sure it is recognized by Device Manager along with a COM port number associated to it. LG UPPERCUT should then be able to see the phone model and COM port and launch, it won't launch otherwise. Once LG UP is running, load up the .kdz image and click UPGRADE. As long as your phone is able to remain in Download mode for more than 30 seconds you're good. If it continues to reboot short of that, give it another thorough wipe in custom recovery.
Once you have flashed stock, you can go back to adb or fastboot and reflash a custom recovery and root program as you did initially. Your bootloader should still remain unlocked after flashing stock so there's no need to run fastboot oem unlock commands again.
