Installing Manually using VCOM Driver


When installing it manually your phone must be turned off, then connect it to your computer/laptop while pressing VOLUME UP or VOLUME DOWN. This will detect and look for the driver.

1. This is the first time that you will connect your phone and it will search for the correct driver.


2. Check include this location ... ... and click on browse. Look for USB VCOM Driver and Click on 2K_XP_COM folder if you are using Windows XP or Win7 for Windows 7 and then press OK when you are done picking the right folder for the driver.



"Your Phone must be turned off when you are ready to connect and flash your phone"

Flashing
1. Launch FlashTool (flash_tool.exe)
2. In Flashtool, Click on Scatter-Loading, and load your scatter file. (see example below)


3. After you load the file, UNCHECK PRELOADER and DSP only (Never flash preloader and DSP if available in firmware) If you can't proceed flashing without these two files then proceed at your own risk, press Press Download to Flashyour Phone.


4. After you press Download Follow these steps

• Turn off your phone (always powered off is a must)
• Press and HOLD volume UP or Down or you can simply press it simultaneously
• *********** USB cable without releasing the VOLUME button(s).
• Keep on repeating until Flashtool detected your phone.

5. If successfully detected just wait until the progress bar reaches 100%. If your phone did not automatically turn on after flashing, remove battery and USB cable. And put back your battery then turn on your device.


"Hard reset your phone after flashing"

Some workarounds: (only do this if your expiriencing the given errors)
If you encounter PMT_Changed error here is what you do:
In Latest version of Flashtool

1. PMT_CHANGED error occur when firmware is not compatible with your phone. Sometimes your phone has a different board version. You should check it too, if your firmware is compatible with your phone.
2. Try Firmware upgrade
3. Try different version of flashtool
4. Try to set Format All + Download
5. Or try Manual Format first then Download.

If you encounter Privacy Protection Password:

1. Open flash_tool.exe
2. Load the scatter file
3. Goto Format Tab
4. Click on Format except bootloader
5. Press Play/Start Icon
6. Then remove battery
7. Insert the battery again
8. Insert the USB cable (you should hear a beep on your computer, and it should proceed in formatting.)
9. After done formatting proceed in Flashing.
10. Goto Download tab (I assume that you loaded the scatter file already)
11. Uncheck PRELOADER (this is very important)
12. Press Download
13. Then remove battery
14. Insert Battery again
15. Insert the USB cable (you should hear a beep on your computer, and it should proceed in flashing or downloading the firmware in your phone.)
16. Power ON the phone after flashing.
17. Restore your IMEI.

For Invalid IMEI (Does not work in MT6571 SoC):

1. Root your phone via vRoot/iRoot/Kingoroot or your preferred method in rooting you device. Your phone must be rooted first.
2. Download MTKDroidsTool version 2.4.8 and version 2.5.3
3. Enable your USB debugging in Developer Option (you also need this in rooting your phone via PC)
4. Okay in your PC -- Open MTKDroidstool version 2.4.8 (Mtkdroidstool.exe) first. Make sure that you connected your phone already.
5. Still in Mtkdroidstool -- Click ROOT
6. In your phone -- A pop up dialogue will appear, just grant or allow it.
7. In your PC -- If root shell is granted/allowed, Click in IMEI/NVRAM tab. If it is grayed out this is the time when you open the MTKDroidsTool version 2.5.3.
8. Enter your original IMEI
9. Click Replace
10. Reboot your phone
