You open the firmware to modify the editor dragon face and loads the firmware to edit , you go to advanced settings, then " system settings " , you will open the file script.bin . Then look for the following lines :
[ ctp_para ]
ctp_used = 1 (1 or 0 according to this on or off the touch)
ctp_name = " gt811_ts " (name of driver ic touch here GT811 )
ctp_twi_id = 1 ( do not touch these lines )
ctp_twi_addr = 0x5d ( not touch these lines )
ctp_screen_max_x = 800 (horizontal resolution of the screen)
ctp_screen_max_y = 480 (vertical resolution of the screen)
ctp_revert_x_flag = 0 ( if we write 1 we invest touch horizontally)
ctp_revert_y_flag = 0 ( if we write 1 we invest touch vertically)
ctp_exchange_x_y_flag = 0 ( if we write one reverses the XY coordinates)
The first thing to check is that the horizontal and vertical resolution in the script matches the resolution of our lcd screen, the most common for 7 "tablets is 800 × 480 although this and popularizing the 1024 × 600, if the resolution not for the touch of the finger will look bad record.
If the touch screen is vertically inverted ctp_revert_y_flag change the value , and if this change ctp_revert_x_flag inverted horizontally , in some cases the two are reversed . If this does not work , leave the values at the beginning and edit the entry ctp_exchange_x_y_flag .
This is an example of what you mean to imply, that I quoted is for editing allwinner firmware and I thought that the only way to not take the disappointment of never again able to use either my lumia 620 could also edit the firmware lumia 620, but how? I have no idea how to open it nor to modify it, I try to access the settings of the touch, or is editing via software to invest vertically from the driver or the driver for the touch, and so could be used FINALLY well my phone, anyone would be so kind as to give me a hand? I want help to do it! I do not ask you do, in any way.
From already thank you very much, Cristian.
PD: I think the idea is good plus it might help people with the same problem as me! That sure will be many.
