Official comment to the flash instruction:

<Before do please make sure 1 Turn off your phone 2 Battery capacity MORE than 30%. Please note that the "Step 3“ in the instruction, please don't choose "DA DL ALL With Check Sum", you only need to click "Firmware→download", after click this option, then please plug your phone to the computer and the phone should turn off>

___________EDIT 1___________

I received a link to the official video flash instruction, but they use Chinese Windows XP and manual driver install in the video so it's rather useless. I suggest the auto driver installer in the link above (http://spflashtool.com) + Windows 7 instead.

My comment to the written flash instruction and SP_Flash_Tool

In SP Flashtool in more recent versions (I’m using V5.1520.00) in the download tab, just over the scatter files, there's a drop down menu where you have 3 choices: <Download Only> (which is default), <Firmware Upgrade> and <Format All + Download>. Here it’s very important which one you select.

<Download Only> will erase the whole particular partition defined by the scatter file and replace it with the one loaded in SP Flash Tool.

<Firmware Upgrade> only upgrade the current rom in your device and that option really should be the default choice in my opinion. At least when you flash a stock rom update for your particular phone and when there is no change to the partition maps (EBR files). Since when device manufacturers started to use unified storage (one partition) there should be no partition changes between different versions.

<Format All + Download> will format the entire phone and this is where things can go really wrong. Without a complete backup (from Titanium Backup for example) you will end up with a brick in most cases. Then when you have gathered the necessary software to get your phone up and running again you will still have lost your IMEI, MAC address, serial number and everything else in the NVRAM. It can be restored if you did a NVRAM backup before you flashed and it can also be entered manually in a rooted device, but it’s hard and takes time. If you don’t know your original IMEI, MAC, S/N, etc from some reason (no original box with that info on a sticker for example) you have a real brick.

In summary I suggest to follow this order:

1. Make a complete backup to Ext SD in the phone in Titanium Backup (root required)

2. Make a NVRAM backup with MTKdroidTools in a PC (root required), or at least write down IMEI (there are 2 in dual SIM devices), MAC and S/N on a piece of paper

3. In SP Flash Tool, change <Download Only> to <Firmware Upgrade>. At least try that option first because it’s the safest and it shouldn't affect the NVRAM. In fact also <Download Only> shouldn't affect the NVRAM but it seems like it sometimes does in some devices anyway.
