[Q] Micromax Canvas Knight A350 boot issue! Problem with device turning on. topic

Okay, Hi. I will try to give all the details as far as possible about the issue.
Canvas Knight A350 running on Kitkat 4.4.2. It was not rooted when the problem occured.
The problem is whenever I turn on the phone it shows the MIcromax logo later powered by android and canvas knight welcome screen for 5-7 secs but gets switched off automatically after that. The home screen does not appear. Sometimes for flash of a second it appears and I could see the wallpaper, app shortcuts in the background out and the "power off shutting down" screen

Things I've already tried :
1. Charging the phone : Whenever the charger is connected it shows the charging symbol with the lowest battery and after 5-6 seconds it says "Error, Please remove the charger."
2. Wipe Cache Partition : Installed recovery with SP Tools and wiped cache. No update.
3. Wipe Battery Stats and Dalvik Cache : Phone started with the screen "Android is upgrading. Optimising apps ... out of 163..." It finished optimizing all apps then shows homescreen for a second again wit the "Power off... shutting down." So issue not solved.
4. Mounting all possible disks etc. : No update still the same problem.

A. The phone has an internal sd card so using the recovery mode I took backup also. But I don't know what all that items the backup option takes? Will it take contacts, sms, whatsapp msgs, application apks? I havent taken any backup using Titanium or anything for the phone / apps / or their data otherwise.

B. I am able to browse the internal sd card folders in recovery mode but how do I copy them to the PC?

C. If I use the Wipe data / factory reset feature of the recovery what data will I lose? Will the internal sd card also get wiped??

D. I'm currently downloading the Kitkat official rom to update it manually using recovery. Will that also make me lose all my data on phone storage - contacts, settings etc.? and internal sd card?

E. Is there any better way to solve my problem without the whole factory reset or flashing ROM? Because appears to me that its some software glitch and the phone is not actually bricked!! (the appearing of home screen and wallpapers even if just for a second) Maybe something is sending a power off command to the phone as soon as it gets turned on?

F. Could it be a hardware or battery voltage issue? Should I post the battery test readings from the factory mode? How to conduct the test properly?

[ GUIDE ] How to solve ' Invalid IMEI ' error on Micromax Canvas Knight topic

This guide will help you gain back your IMEI on your Micromax Canvas Knight [Only if the Baseband is not lost].

NOTE :

1.Only for ROOTED devices !

2. This guide is useful only when the 'Baseband Version' of your device is avilable. If the device is showing 'Unknown' in the Baseband tab in the About device section , then you will have to use a different method.

3. This method is also applicable for many other MTK6589 and MTK6592 devices [Even more , maybe].


STEP 1 :

1.1 Go ahead and install Mobile Uncle Tools from Playstore .



STEP 2 :

2.1 Open the Mobile Uncle Tools and grant Super User permissions
2.2 Click on Engineer Mode and then click on 'Engineer Mode (MTK)'

This will take you to the MTK Engineer Mode.

STEP 3 :

3.1 Now swipe right once and you will find the ' Connectivity ' tab.
3.2 Under this tab , you will find ' CDS Information '. Click on that.
3.3 Next , find ' Radio Information '.
3.4 On opening Radio Information , you will find 2 options : Phone 1 and Phone 2 .
This denotes the IMEI slots for the 2 SIM cards.


STEP 4 :

4.1 You'll find a page with ' AT+ __________________ '
4.2 Now , just after the '+' , type 'EGMR' . As you start typing , it will automatically pop-up four messages.
4.3 Select the first one from that : AT+EGMR=1,7,"".
4.4 Between the two double - inverted commas , type in the IMEI 1 . You can find the IMEI from the backside of the device [If at all you have not removed that TAG] like this .

AT+EGMR=1,7," 15 digit IMEI number "

4.5 Now click on " SEND AT COMMAND ".

You will receive a small toast message like this " AT Command is msent ".
That message shows that the IMEI has been restored !

Now , repeat steps 4.1 , 4.2 and 4.3 for Phone 2 .
But , in step 4.3 , select " AT+EGMR=1,10, "" " ( It is the second option )
Repeat rest of the steps and you will have both the IMEI written on your device.

To check , just type *#06# on dial-pad and it will show your IMEI numbers .

STEP 5 :
* Reboot !


And then the SIM cards will be detected .
