[Q] Karbonn A21 got formatted accidently. what to do?

Hello Everyone,
2 days ago i tried to hard reset my Karbonn A21 android phone. i pressed Power+volume+home button. after that there was an error displayed on the screen saying "ENTRY QPST DOWNLOAD". i quickly searched on the internet but wasnt able to find any successful link. but then my computer asked me to format the device, i thought this will reset my phone but unfortunately i was totally wrong. after the format i tried to start my phone again but nothing happened. i also tried different combinations of keys but nothing happened not even a single pixel lit up lol. then i downloaded cherry mobile flare software and AIO flasher and all the image files and other files required. they didnt work for me. now whenever i connect my phone to the laptop, i get Qualcomm HS-USB QDloader 9008(COM 4) in ports section of my device manager. i tried to flash it in fastboot in AIO flasher. it says flashing but nothing really happens even after 10-15 minutes. all the online forums i searched they say enable debugging mode on ur phone in order to reboot but i dont know how the heck i can do it when my phone doesnt even start up lol. I am left with a dead phone now. can anyone please help me out and solve my problem. and please advise me step by step what to do next in order to get my phone working...please...

First Don't panic
I will provide you with steps to unbrick your device
1. Install AIO Flasher to your PC. Download from here
2. Install PdaNet on PC. Download from here [pdanet.co/bin/PdaNetA4126.exe]
3. Get recovery and flash. (CWM preferred, download and know how to flash from here)
4. PM me to get stock ROM.
and hit thanks if it helps.

Bricked Goophone N3+

Hi everyone,
I tried flashing a new rom on my Goophone N3+ (i think it's a MTK6592), but something went terribly wrong and now the phone doesn't boot.
I can't even access the recovery mode or the download mode: the phone just won't turn on.
I tried connecting it to different computers with different cables, but it's always recognized as an "unknown device".
Is there a way to unbrick it, or at least make my pc recognize it?
Thank you in advance and sorry for my poor english.
Remove battery, plug phone on USB and check for COM port in device manager.
If there is a COM port for only 2 seconds, there is unbrick possible.

[HELP] Cannot power on Z7 Max

Hello all, hope I can get some help here. I was trying to boot my phone in recovery mode to clear the cache but the phone cannot be on at all. There is no response now when I try to on it normally. I've tried charging it but the phone does not respond at all. When I connect it to my pc, it detects it as a USB drive but says it has malfunctioned and cannot recognize it.
I'm not sure what happened exactly. Need some help~

Bricking the phone, please helpp !!

Hey, I got wiko ridge 4g that was bricked, it won't turn on but the light is blinking when battery is not full when i connect him on charger. I have connected the phone with PC via USB and he recognized him as 'qhsusb_bulk', i tried to unbricked it with SRK Tool 2.0, but i can't turn on usb debbuging and i don't know if the phone is rooted or not, but i did it anyway. So i managed to delete partitions with that program, but later the phone was recognized as Unknown USB Device. So my question is : is there any other way to brick the phone back, without phone being turned on, via PC ?
Thank you very much.
