That is something installed in your android /system

it cant be removed now because it has REPLACED the audio files in your android/system ..

Only if you had a backup ....but backup and restore doesnt work at the moment in eklovya's CWM recovery

---------- Post added at 09:34 PM ---------- Previous post was at 09:28 PM ----------

Backup Can't be made currently in Eklovya's CWM Recovery... It reboots while backing Up Data...

It doesn't show "Backing up complete" message
[Karbonn A21] theboyzrockz:
So what do you suggest?

Is there a way I can replace the changed audio files with the originals?

Also I noticed.. If I put on the headphones, the sound is perfect.. only when it's on the speaker mode(audio files from phone), a loud hissing noise..

Replacing the files sounds like a solution to me. But of course.. I am shooting in the dark.
[Karbonn A21] Nishchay1:
You can try adjusting the DSP manager settings ...

try changing the equalizer or disable the equalizer...

try different combs until you start to get a better and clear voice

i'd recommend to disable bass boost and minimize the bass lever ( first bar in custom equalizer graph) in custom equalizer settings
[Karbonn A21] theboyzrockz:
Equalizer doesn't help. I thought of that already, so downloaded an external app which plays with the equalizer settings. It didn't make any difference to the sound. Always a loud incoherent hiss. I don't even thing there's a sound other than the hiss accompanying it. I guess the Beats Audio installer played with the audio codec. Now the rendering goes for a toss while the output is fed to the loudspeaker.

Or could it be a hardware issue?
[Karbonn A21] satan89:
You have to wait for ftf firmware to be released (don't know if its already there) then reflash rom.

Also look in your PC suite if repair function is available. But this will reset phone and you will lose root and cwm recovery.

Or just wait it out till a custom rom comes out
[Karbonn A21] theboyzrockz:
There's no PC suit provided with the phone. I didn't find any software/firmware support from the manufacturer. I don't think they'll offer OTA upgrade to JB either. Anyway a custom ROM is one option. Other is to give the phone to the service center and pay them to reload the phone with ICS again. Maybe that will help. Till then my phone is mute.
[Karbonn A21] satan89:
Ya but if you are giving to service center you have to reflash stock recovery and unroot phone. I'm quite sure rooting voids warranty.

Also have good excuse why sound isn't working, or tell it had problem on purchase itself
[Karbonn A21] theboyzrockz:
Yeah. Might just have to shell out a few bucks. Hoping it won't be too much. I realized the dark side of new cheap android phones. Limited resources. Hope these will catch up soon.
[Karbonn A21] satan89:
Not much hope here but try this link and select a k series phone. Some have drivers and PC suite links. Just might be compatible with A series phone.

Anyhow now that cwm is there for this device its only a matter of time till custom rom is created
[Karbonn A21] theboyzrockz:
Thanks man. Will try it out and let you know if it works.
[Karbonn A21] Nishchay1:
CWM doesn't even takes backups dude :P . Else i would've started making a custom ROM for the device
[Karbonn A21] satan89:
Even if it did I think its cwm version 5.x

You need cwm 6.x + to safely flash ics and jb roms (AFAIK)
[Karbonn A21] Nishchay1:
Yeah it is 5.0.2.8 ... We need a 6.xx :(

Beats audio problem

Sir please help me out ... i have installed the beats audio on my device and it had made my phone speakers to make cracking sound .i uninstalled the app.But the drivers are still there .I had not backed up the setting (my fault). i had tried to wipe cache.factory install,unrooted the device..Still no solution. Can anyone in the forum can help me out...i have no stock rom with me :(..........

please help out......
[Karbonn A21] satan89:
Unfortunately there is no stock firmware available for download with which you can flash device. And don't worry about not backing up as I heard its not working properly.

Only thing I can suggest is uninstall supersu and any other 'root apps' (titanium backup, set CPU, ad away) if you installed them, then return to service center and tell them phone was faulty on purchase. They might reflash or replace your device.

but under no circumstance should you even mention that you rooted your phone, since rooting voids warranty.

Karbonn A21 does not connect to car bluetooth, no jelly bean update

Hello

When trying to connect Karbonn A21 to car bluetooth system, the connectivity only allows for music to be streamed from phone to car audio. The cellphone can't connect with the car's bluetooth phone system because of a missing chipset in the phone - as I have been informed by Karbonn's support. The conversation with the support people by email is listed below. When trying to connect KArbonn A21 via bluetooth to car's system, I get "unfortunately the process com.android.phone has stopped" on the phone. I have even rooted the phone and removed unnecessary apps but to no avail.

Anil

Hello

Karbonn A21 does not connect with car bluetooth systems. Many users are facing the same problem. When Karbon A21 is connected via bluetooth to car's phone bluetooth system, the error -'unfortunately the process com.android.phone has stopped' comes on all Karbonn A21 phones.

Please guide how to solve this, even your service center, after phone reset & software upload, hasn't been able to solve this problem.

Anil

Dear Customer,

Thank you for contacting Karbonn Customer Care.

With reference to your query regarding connectivity with Bluetooth , we would like to inform you that it’s not handset issue , it’s compatibility concern of connectivity with car Bluetooth , which is not compatible with our device . so we can’t provide any confirmation & support regarding this .

This response is not correct. Except for Karbonn A21, same cars Bluetooth is able to connect to all other brands of phoned including Sony, Samsung and Micromax.

The issue is with software of Karbonn A21, pls see if you can provide jellybean update for A21 model.

Anil

"Dear Customer,

Thank you for contacting Karbonn Customer Care. With reference to your query regarding connectivity concern , we would like to inform you that there is no connectivity procedure with Car Bluetooth . "

Does it mean Karbonn A21 will not connect with any car's Bluetooth system?

Hi all,

I have got this mobile from a second hand and have some troubles with it so I would like to reflash the original ROM to make it as the original. I have done some research but so far I can't find anywhere RUU version: RADIO-0.15.31501S.19_2 (I can see that on the HBOOT screen) with 1.53.61.3 (this showed me the flashing app as the original soft) software version as I get the 131 customer error and it won't let me to do it. The CID is ORAN001 or something like that. I understand that I need to change that to SuperCID or use the exact original RUU to make the phone work. The sd card won't mount so I don't think it's possible to change the CID to 11111111. It looks like there was the original software (don't know which one but it's in the UK) then someone has unlocked the phone and installed through CWM Orange UK Ville.zip. and finally me another Ville.zip (JB but wifi and some other features won't work). The phone is soft bricked now and won't work as I couldn't reflash the original ROM because I don't have it and when I was trying to reflash it by version 1.53.161.3 the 131 error came up and ended my effort.
