It is advised to attempt updating with your memory card removed to reduce chance of bricking this phone.
To update the phone, among the apps that come installed with the phone there should be one called "system updates" launch it and click check for updates, it should locate an update of 70~80 mb, accept whatever the phone asks you and the download should start,
Note: your network must be steady throughout the downloading process,
If your network goes off the download will freeze and cannot stoped, restarted or resumed
If you download makes no progess after 10 mins it is frozen

To fix this open a file explorer and delete this folder "system_updates" and this file "update.zip" from the root of you memory card.
Then goto Setting>Apps and locate the "system updates" application click it and click "force stop"
then click "clear data"
Now you can attempt to download the update again

If the update downloads successfully, open "system updates" again if you minimized it, you'll see a button that says "apply update" or something similar, click it, answer yes and your phone will restart and install the updates
Note 2: if you see a screen that says signature verification failed, you have to select reboot and start they process from the beginning again , which means more downloading doh

Simran94:
. download MTK engineering tool from play store, install and open it. click on mtk settings, swipe to the left and you will see CDs information, click on it and then click on radio information. then select the sim card you want to change it's imei and type in the command E and you will be given a list of commands. if it is sim1 you wanna change it's imei select 1,7 but if it is sim2 select 1,10 and type in the generated bb imei. but make sure you leave a space between AT and EGMR

It works for both sim one and two although only on Glo Sims, so it depends on which sim port and sim u own
