[Q] booting problem in karbonn a30 after flashing new rom

Hi Friends,
My Karbonn A30 has bricked. I did so many experiment on my phone and also stucked several time with some problem but i did solved that problems. Unfortunately this time i am helpless with my phone.Now i am going to explain you what i did with my phone and what problem i am facing.
NOTE: My phone was rooted by using "Root_with_Restore_by_Bin4ry_v18" process.
Two days back i flashed TITAN MOBILE ROM in my Karbonn A30 but that was unsuccessful,After that my phone was not able to boot and also it was not able to boot in recovery mode using Volume up + Power key. Then with some R&D i get a new option using Volume Down + Power key that option is for my mobile hardware test. In that option i formatted my "emmc" then after my phone was able boot in CWMR recovery mode.Then i wiped my all data and system using CWM Recovery,Also did Restore factory.
After that i was regularly getting error message on my phone notification " Phone storage corrupted,Format it" Then i formatted that. Then i installed my all apps from by apps_backup. When i rebooted my phone,again i was getting same error message and didn't any option except format it.
Then i decide to check this error after unrooting my phone. So i remove root access. After that i was not getting this error.
Yesterday again i rooted it with same process and again i was getting same error message after installing apps and reboot my phone.
then i decided to flash new rom with same company phone(Karbonn). So i got ROM for Karbonn S5 from google. I flashed that successfully on my phone i was very happy because this rom was having Jellybean OS(4.1.2). But after some time apps started crashing when i logged in my phone using my gmail as usual i did after every factory reset.
Then i re-flashed the same rom(Karonn S5). This time i decided to do factory reset using phone setting before loggin in google account.
That was my blunder mistake. After pressing factory reset my phone got stuck in boot screen.
Then i tried same option to solve it (Volume down + power ) so i can format emmc again to resolve it. But this time after formatting emmc i was in the same condition on boot looping.
I am not able to go in recovery option using my phone key.
I need you help, i can not go service center because i voided my warranty.
NOTE: Currently my phone is not rooted,I checked it using ADB commands. My USB DEBUGGING is showing on but when i put my phone in" phone hardware check mode( using Volume Down + Power key)".
Plz HELP ME TO SOLVE IT.

[Q] my bricked micromax a88 phome

Recently, i rooted my micromax a88 (Ver. 4.1.1) through kingo tool and after that i installed chainfire app. But after the reboot, it is stuck on the starting logo and nothing seems to be working. It is only showing the Recovery mode and the Factory mode when i start it with the volume up and down and power button pressed. I even did the factory reset, cleared cache but it still shows the start up logo and does not do anything beyond that.
I even tried connecting it to pc using USB cable but its not detecting my device but earlier it was showing up. On connecting it through USB cable its only charging the phone. Someone please help as i have tried searching the internet for resolution but it just not seems to be working.

I get error 2004 ( I've installed Meditak Vcom and my device usb driver)
when I turn on my phone with battery it reboots every 5 second , so windows and sp flash tools can't recognize it.
I tried to flash it without battery,when I pressed volume down phone turned on by vibration and after a while it turned of by vibration again!
I can't access to bootloader menu when I press " volume up +volume down + power button" nothing happens! it just turns on phone!( and crazy loop boot circle happens again!)
I'm using windows 8.1 last update , every thing is Ok and my cable is Ok my sd card is Ok and I've downloaded Right ROM for my device(MT6589) and also I'm using sp flash tool last version!
**** I've got access to fast boot mode ****
My main problem is with Error 2004! help me out PLZ!
I couldn't put any screen shot cuz I'm a new user, Sry!

How to repair my dead rooted android (Micromax D321) ?

Few days ago I rooted my android phone (Micromax D321) using Kingroot. It was going well but after few days my mobile stopped working. I removed battery to force switch off phone and booted it. It stucks on boot screen. I tried to flash stock rom using SP Flash tool but after flashing successful phone was in same condition. When I tried to update android Via adb it is showing "status :0, installation aborted" after certain progress. So I tried to factory reset mobile from recovery menu and then it is showing " error: cannot get the phone encrypt state". I am totally confused how to solve this issue.
