So here is manual how to repair chinese phones with our tool.

1. Run Latest Chinese cocktail ( MTK tool )

2. Select your model from list.
IMPORTANT: if your model is not in list it doesn't mean that is not supported, we support all MTK based phones, it just mean that we have not firmware maybe for this model. That is not too important which model you will choose for first conect. After connect you will see CPU info - so this must be correct with selected one.

3. Choose please working speed. Some times some models work only on 115200 speed.

4. Press connect botton and you will see next info like on the picture.
5. If you have message like: Unknown firmware version you need make back up before any procedures. And send it to [email protected] for next updates. With all phone info.

6. So now you need press botton: "Format eeprom area"
It will take some times.

7. Press and hold phone "Power" button during 30-40 sec to make phone Powered-On.

So enjoy your phone now.

IMPORTANT: if after format your phone not working - write readed before full flash back up and inform us about this via E-mail. We will make update for your version and model.

All cable schemtaics at support area. Use correct cable. Guys I realy don't understand what is the problem? Check schematic from support area - than check which cable you are using and enjoy.
