Buddy, my phone is not rooted yet, but upgraded to official JB 4.1.1 through micromax service center. As sound intensity was a little low. I entered into engineering mode to adjust it to a desired level. Now my Loudspeaker sound is fine, but sound from my headphone became noisy. Is there a default value which comes with factory settings. Kindly help me out.

No problem ... you have problem I've a solution

Audio Settings :
To Go to engineering mode go to your dial pad & type *#*#3646633#*#*
In here Just Select audio then go to Loudspeaker Mode
Now scroll down to Max Vol 0-160: By Default it is 128 & You can change it to 160 but at 150 and above i noticed it produces more noise then
voice. When selected your preferred settings Click on set.
post me again if you need further help ..

I am on legolce canvas 4 ROM. they say FM is working on that ROM . but it's. not working now. I suspect it has something to do with me selecting radio button for antenna type to earphone or do I have to flash some patch on top of legolce for top work.
I even tried to flash grand rom v3.FM
worked on it.then I re flash legolce . still FM not working. old help me

This is not how you reset the audio settings in MTK mode. What he meant was to reset the values to the default before he made any changes and messed it up.
---------- Post added at 06:42 PM ---------- Previous post was at 06:40 PM ----------
I also have this same issue. I messed up with the audio setting of loudspeaker, rinde, mic, etc and now I don't how to reset to default. Please help.

I have a similar problem, but more severe.
I have an unrooted Siswoo C55 device. Chipset MTK6735 running Android 5.1 I was trying to adjust the baseband frequencies to see if I could enable the LTE, but I ended up making it so I can no longer send text messages. I can still make/receive calls, and I can receive texts, but it says that its not connected to a mobile network in the engineer settings even though the rest of the phone thinks that it is. I need to st least be able to connect back to my USA Band, AT&T, 3G network. Any ideas what I screwed up and how to fix it?

Yesterday my Eluga DL1 also did exactly the same thing, one minute the pin to unlock the keypad works the next minute it doesn't... weird. I know I am entering the correct code and I can guarantee no-one else has changed it!
Likewise, I can't do a hard reset because that also requires some sort of pin. Also, none of the lockscreen bypass apps on google play work.
Did you ever manage to fix this?

No struggling with this one
Hi all, I am writing with an interpreter so I apologize for the errors.I have the same problem with Eluga DL1, unfortunately I have a problem with locked screen and hard reset wants a password. Wi-fi and USB ports are inactive and it is not possible to activate them.I found about this problem on samsung and there are several fold typing wrong password leads to automatic reset, or eluga it will help if the phone pretty blocks?

Hi there!
I guess I am a junior member in this club.
It's difficult for me to choose one thing in the story:
the ever-so-poor Panasonic design,
its unreliable and erratic functioning,
the awful hard reset,
its customer attention taking days to start doing the right thing in symbolic amounts, or
the fact that the want the phone to travel all across Europe for a fix in Germany.
Did you find another way out (better, for sure)?
Cheers !

IMEI is quite easy to fix ! Use MTK Droid tools to write ur imei or S/N Write tool. There are many tutorials browse through for how to use this tool !
Flashing stock ROM through SP should solve imei. First select format in sp and then flash ROM through sp. Then after first boot take imei backup as mentioned in this thread. And replace it every time u face problem !

Hey! I have got the same problem in my Canvas HD. What I do is:-
1. goto dialer and type *#*#3646633#*#*
2. Goto CDS information
3. Goto Radio
4. On the command bar, type AT+ EGMR, 1,7"YOUR IMEI"
5. And send command
If it says command sent, then good but if not, remove SIM and try again .

Note: For SIM 1, the command is AT+ EGMR, 1,7"YOUR IMEI" but for SIM 2 it is, AT+ EGMR, 1,10"YOUR IMEI"
I hope you got the answer! :fingers-crossed: :fingers-crossed:

Brother I have checked this but this solution is not working on Karbonn S5 Plus it is for Karbonn S5
and as I have wrote above there is neither fastboot mode nor any recover options are available when I start it while pressing Volume up or Volume down keys
There is only Black screen
only a sound notification comes when i attached this to my computer
If the clues above mentioned are the adequate for any solution then I will strongly thankful for that.

Try to obtain the boot.img, system.img and the kernel for your phone. The company would have released the source for your phone. And try to enter fastboot mode to flash those img files. If that doesn't work, then I'm sorry but unless there's some miracle of sorts, its not going to work.
Manpreet,Give back your phone to the place where you bought it and just use your acting skills.it happened to me and i gave my mobile back to the shop and the shop gave it to warranty location.After 1-2 months you will get your phone back and if it doesnt get repaired you may get a new one...
You have bricked it

This happened with me too few months back. I was trying to do WCDMA mode only cause of good 3G network and connection was dropping and did GSM and stuck there lol the only thing I remember I did was flash the phone since I was already on Custom ROM
Try to power off and switch on back and see if it helps

Yes bro It did solve my problem by flashing Custom ROM but mine was HTC device and It already had recovery and rooted so was easy for me to flash new ROM just like removing Windows 7 and installing Windows 8 type of scenario
Here you're having a clone of iPhone 5s and AFAIK clones don't have any developments on XDA but you could just flash official clone iPhone firmware and it will solve your problem. Google up for iPhone 5s clone firmware and update it.
Did you try Airplane mode and power off etc? and see if that solves your problem

Hi,
i am not sure if this would be of help but you can try the below steps and if that doesn't help register yourself at xda and post a query there.
http://forum.xda-developers.com/t2-ultra/help/sound-update-to-lollipop-t3128736
Try safe mode to verify if sound is working or not.
1. press & hold the device Power button
2. power off options will appear.
3. on touch screen, hold power off untill, reboot to safe mode dialogue appears, then click OK.
4. when boot done, try playing any audio/mp3 file,
5. if working well in safe mode, then some 3rd party app is causing trouble, find it & update or uninstall it.
6. if in safe mode, you can't hear sound, thats bcoz lollipop update went wrong bcoz of you have update on root access.
7. To exit safe mode, turn your device off and on again. thats all!
