1. you must read FAQ here: http://www.gsmhosting.com/vbb/forumdisplay.php?f=296
2. you must read information from C:\Program Files\InfinityBox\Documentation folder
3. you must make "search" in this forum
of course, you must be NOT LAZY before you will start to make steps 1-3

After you have some free time after steps 1-3 you must read this:

Due to a lot of different models with the same name but absolutely different hardware,
bottom connectors and different pinouts we recommend you to make detailed description of model,
attach phone photo, phone bottom connector photo and information about Gnd and Charge pins on phone bottom connector.

After you have this information prepared, please, check the next detailed description how to get pinout for your model:

use "Cable Selector": http://forum.gsmhosting.com/vbb/showthread.php?t=398297
if not helps, please read: C:\Program Files\InfinityBox\pinout\ChineseMiracle.txt

"ChineseMiracle": how to repair "reboot with SIM card"

1. make full flash backup for emergency case (use 921000 speed for fast operation)
2. select "safe format method"
3. make "format ffs"
4. remove/install battery
5. press and hold phone "Power" button during 30-40 sec to make phone powered-on
if phone Ok go to step-6
if phone not Ok, go to step 2 and select "complete format method"
6. restore original imei
7. if phone has touchscreen LCD make calibration: click to LCD corners one by one

if still no luck: check phone hardware
