NOTE:
Write down you imei somewhere (press *#06# on dialer)
You will be needing it
Method:
-Install all Drivers
-Put scatter file ,extract rom and preloader,dsp_bl in one folder (makes things quite easy) replace if asked
-Turn off phone
-Open Sp Flash tool open scatter file and select the scatter file u downloaded
-put tick on all files on sp flash tool and select its corresponding file (for eg "ANDROID" is system.img)
-Click Firmware Upgrade on sp flash tool and connect phone (turned off)
-It Will show error! Disconnect Phone
-Remove tick from all files
-Now put tick on "BOOTIMG" "UBOOT" "RECOVERY" "LOGO"

-(to navigate in recovery mode press vol + to go up press vol - to go down and press power to enter selection)
TO MAKE BACKUP: in recovery mode enter backup and restore, and backup it will take few mins
TO COPY BACKUP: in recovery mode find mounts and storage and turn on usb mount and connect your phone to computer while being at that mode a removeable drive will show up copy the clockworkmod folder
Okay now listen carefully go to the folder where you downloaded the rom (the one you downloaded from me) find the file system.img
rename it to system.yaffs2.img
then go to the folder where you copied the backup to you will find also system.yaffs2.img there replace that file with the file from the rom (the one you renamed earlier) next open the file "nandroid.md5" with notepad delete all the text it has and save it
now copy this folder back to your phone (replacing the old folder) and the Super su zip u downloaded earlier reboot your recovery (after copying back the backup it is important) NOW:
- factory reset
- go to backup and restore -> advance restore ->restore system
- go to update from sd card and select the super su zip
- reboot your phone normally
After the reboot your phone will be rooted But your imei will be lost
Here what you will do restore your imei:
1. remove all sim cards from phone ,turn on the phone in normal mode and connect it
2. open mtk tools press root button it will ask you for some thing just click ok
3. Click replace imei and enter the imei numbers (can be found on phone box or back of phone)
4. Click ok reboot your phone check for updated imei numbers
And Congratulation Your Phone is Rooted

simply root it with Vroot
This method is very complicated just simple root it with voot 1.7.2 sofware , you just all those drivers witch come with Q mobile software. Juts simple put mobile in dubugging mode , once sofware detected your mobile just simply press the Root button , your wmobile will restart once and its finally rooted . No need for all this stuff. I rooted my friend's A2 Classic with that method , if you want some screenshots i can provide that to.
Easy Rooting Method.
- I am not responsible for bricked phones
-and i am also not responsible if someone hit a bricked phone in your head
-don't worry your data remain safe :laugh::laugh:
Method:
first and first download the software from attached files below the post :good::good::good:
1) Install all the drivers (as the original post suggested ADB and VCOM )
2) turn USB debugging on.
3) Install the software , its in chinese but not very difficult to understand Just press the middle button once installed it should be looked like this (check the attachment )
4) press the button , let the software do its things, once your cell phone restart check the SU app in the drawer.
Caution: Do not Factory restore your phone after freezing apps or modification you will end up in a boot loop.
So what you do with this little Rooted device ?? duh off course make ext 4 partition on your SD Card and link your newly download aps using link2SD . no worrying of low space

I had the same problem, all you have to do is open data.ext4.tar or data.ext4.tar.0 from from you backup folder i.e. clockworkmod/backup/(whatever the date is) with winrar in your pc and extract the nvram folder then copy paste it to your device's root directory's data folder and replace the older one or just delete it before pasting your backup's nvram folder!

Thanks for the post.
Sir, I have followed your guide for rooting and READBACK both worked perfectly. But for READBACK normal USB driver installation worked and when tried to root drivers were not working in SP Flash tool so installed PDAnet drivers. Now I want the IMEI backup for repartioning guide but unable to do it as the mobile is not being fully recognized in MTK droid tools. MTK recognizes Baseband Version & IMEI 1 & IMEI 2 but in lower bar say unable to reveal device, please reconnect.
Thanks and Regards
Deepak Gupta
Thanks for the guide. Finally everything done and completed.
Problem I was facing of mobile being not able to recognize in MTK droid, was fixed when in mobile under PDA app I switched on USB tethering. Hope this helps everyone following this guide.

This error is quite common . Jus delete the stock rom using the SP Flash tool. Then , reflash the Stock ROM , this will fix your baseband. Then you can use the MTKDroid tools to restore the IMEI.
hello every one... i had this problom and i fixed it, i see lots of peeple having this problom
i hope this saves some one else's 3 day of life !!!!!!! My phone was MT6572
"" MTK ONLY ""
Your device doesn't detect simcard?
you flashed your phone and it can't connect to gsm networks?
is your phone stuck on airplane mode and you can't tun air plane mode off??
you can't change imei?
in MTK Droid tools you get these errors??
Baseband v: -----
and even when you root your device you get this error?
--- ERROR : pttycmd1 device NOT found!
you get this error in IMEI&SN write tool?
Enter to ModemMeta Fail

3-Format your phone "WARNING!! DON'T FORMAT BOOTLOADER"
3.1 press start

4.2 Press start
4.3 turn off your phone
4.4 connect usb cable to your phone
4.5 wait for the process to compleate...
4.6 remove the usb cable
5- if you want to do something with the mount screapt or ect... its for the best that you do it now
6- in SP flash tool uncheck every thing

6.2 click on the location area of the SEC_RO
6.3 select your own SECRO.bin or NODL_SECRO.bin
6.4 click download

Root Your Phone if you didn't
9- Select ROOT in MTK TOOLS
10-in your phone allow super user or super su
when the light in the app turned green you are ready to pull the new imei to your phone

select IMEI/NVRAM
insert the new imei(s) and ok....
10- reboot your phone and see the imei *#06# it is ok now :victory:
if i helped you press THANKS :good: button
First of all: Instructions very unclear!
Second of all: Doesn't work for all the MTK phones. On my Jiayu S3A it didn't work. From a few days ago I can't connect to Orange (but to Vodafone as an example, I can), and this didn't solve the problem.

Flash the secro.bin file with sp-flashtoo, that shuld fix it. If the secro.bin file i did upload didnt work for you find the one that is for your device in its backup (from backup that u take from ur device before) or flash files for sp-flashtool (from internet)

One week after i brought my phone, I accidently formatted my device using sp flash tools and lost the IMEI/NVRAM. It has been a real pain for me to repair it because i was new to an mtk device. Finally figured out how to repair by doing many search. So I made this thread to share the working methods to help those people who are suffering from invalid IMEI
So let's start.
Always remember "Prevention is better than cure". If you are planning to flash a custom rom, First of all Backup your IMEI. Don't Trust that a custom ROM flash will not delete your IMEI number. because odds are it will. It's important to store your backup to external SD because some ROM flashing techniques will erase your internal SD. so the best way to keep your IMEI number is to take my advise and make a backup.
Some Video tutorials will be added soon
DISCLAIMER: Do not do try any of these methods unless your IMEI has been lost! Doing so may permanently corrupt your imei partition.

I tried this method but every time I tried, I was getting "Entre Meta Mode Failed" I am unable to understand why my device is not going into meta mode. I have written IMEIs and MAC IDs with this tool on Canvas HD, hell lot of time.
The process for Canvas HD is little different, I used to select both the database files, first "BPLGUInfoCustomAppSrcP_MT6589_S00_MOLY_WR8_W1248_MD_WG_MP_V6_P18" and then this one "APDB_MT6589_S01_MAIN2.1_W10.24" secondly I used to power on my device "Power On" msg was displayed on SN Write Tool.
I tried all possible scenario, selected only one database file, changed the sequence of selecting database files, tried to turn it off after hitting start but worked nothing for me.
When we select Database files the window opens twice, did you select same file both the times? And have you tried to write all the things together, means IMEIs, MAC ID of BT and MAC ID of Wifi in just one go?

Yes i select same file for twice name of file is given above in my post and i never try to write other things like bt address, imei same time but i want to say don't try to write bt address because it will show error every time when you try to write and i also want to say that imei number can be written with this tool but select only imei don't other things like sn number, wifi mac address.......etc. try one thing only at same time. means when you want to write imei then select only imei but you can choose sn and wifi mac address at same time it can be flashed successfully......

2)INVALID IMEI(Lost/Invalid IMEI)
What you need:
1.MobileUncle Tool apk.
2Your IMEI number(Copy the IMEI of the phone box or from the bottom / top of the battery)
Step by Step
1.Run MobileUncle Tool
2.Enter Enginering Mode
3.Choose Enginering Mode (MTK)
4.Choose Tab Connectivity
5.Choose CDS Information
6.Choose Radio Information
7.Choose Phone 1,Write on the row:
AT + EGMR = 1.7, "IMEI_1 NUMBER HERE"
- Press SEND AT COMMAND
8. For Phone 2, write:
AT + EGMR = 1.10, "IMEI_2 NUMBER HERE"
Press SEND AT COMMAND
9. Restart Phone n Done
Dial * # 06 # to check your IMEI
#TO GET YOUR SECOND IMEI NUMBER,JUST ADD 8 TO THE LAST 3 DIGIT OF YOUR FIRST IMEI

There are so many reason to occur the issue you mentioned
1) Virus/ malware infection
2) Contact database corrupted
3) Due to 3rd party application which share your address book such as Viber, line ets..
4) Sim card contact memory location having issue with data filed
5) recently you imported contact complicating or address book limit exceeded
Simply you can reset the device and most probably fault will be fixed but before reset the phone make sure all contact backup to the your google account.
Hope this answer help you!

I found a little thing that make that command failed; there's no space and no . (dot) within the command, so the command should be
AT+EGMR=1,7,"IMEI_1 NUMBER HERE"

Hope it helps! Regards!
No permanent solution
It requires root. Also it's not permanent solution. After performing hard reset, imei are erased again. So give permanent solution.
I used Maui meta to recover my imei you guys could also try sn writer

Thank you very much (an original author and you)! Really.
( AT+ EGMR=1,7,"IMEI_1 NUMBER HERE" worked for Phone 1 and AT+ EGMR=1,10,"IMEI_1+8 NUMBER HERE" for Phone 2 ( IMEI1 + 8 ) )
Btw, a command *#06# shows two same IMEIs, but SIMs and dialling works. Is that okay?
What happens when I dont have my imei number
What happens I.don't have my original imei number
Dailing the 06 thing says invalid IMEi
The sticker on which the IMEI.number was is so faded I cant make out jack.....
The box is gone
Hellpppppppp????
