[TOC] #### **5.2.1 MST scheme** Taking board number：08-MS80105-MA200AA，TCL MS801movement，L46E5500A computer type，main chip MSD6A801，storage W25Q16 as the example.The ISP path and serial port of this version are the same port,both have 2 sets.Line orders 1 and line orders 4 can both receive printing message and and reveal the MBOOT program alone,and here we use line orders 1. The way to back-up the program : “ISP automatic identification”→“Read”→“Save”. Step 1 : The VGA ISP port should be connected with board correctly by VGA line.Open the software to the main interface,first click,then charge the mainboard(Keeping booting up,both with standby power supply and main power supply),then it will hint to detect the type of main chip.  Step 2 : Click ,809F will read and verify once automatically.(If it verifies by mistake,please set the low speed in the “setting” menu to read again )  Key point:“ISP automatic identification”“Open”the file waiting for burning“Write” Step 1 : The VGA ISP port should be connected with board correctly by VGA line.Open the software to the main interface,first click,then charge the mainboard(Keeping booting up,both with standby power supply and main power supply),then it will hint to detect the type of main chip.  Step 2 : Select the program file waiting for burning;  Step 3 : Setting the data reconstitution function to reserve the information like original MAC address and so on;  Step 4 : Click the,recombine the data automatically,erase,write,verify,you just need to wait for finishing.  Step 3 : Save the file after reading,try your best to name the file in detail,including the manufacturer,brand,model,screen type,main chip type,memorizer type.  #### **5.2.2 Burning Method** Key point:“ISP automatic identification”“Open”the file waiting for burning“Write” Step 1 : The VGA ISP port should be connected with board correctly by VGA line.Open the software to the main interface,first click,then charge the mainboard(Keeping booting up,both with standby power supply and main power supply),then it will hint to detect the type of main chip.  Step 2 : Select the program file waiting for burning;  Step 3 : Setting the data reconstitution function to reserve the information like original MAC address and so on;  Step 4 : Click the,recombine the data automatically,erase,write,verify,you just need to wait for finishing.  #### **5.2.3 MTK Scheme Flashing Method** Mechanism chip : Skyworth 8k27 Main chip : MT8222 Memorizer : MX25L6405 Board type : 715G4089-M01-000-004L Back-up method outline : Setting the VGA line orders by hand → Choose the chip type → Read → Save  **Reading:** Step 1 : Connect the programmer VGA IS port with the board by VGA line correctly and supply the power,open the software to the main interface,like following picture,set the VGA line orders;  Step 2 : Input the type ”MT822X_SPI#ISP” in the “Enter Chip Printing” on the software main interface;  Step 3 : Clickon the interface; Step 4 : Clickto save the file after finishing reading.Try the best to name the file in detail,including the manufacturer,board number,screen type,main chip type,memorizer type for the convenient use in the later.  **Writing:** Set the VGA line orders by hand → Select the chip type → Open the file → Write Step 1 : The same as above; Step 2 : The same as above; Step 3 : Click on the interface and choose the file waiting for being written;  Step 4 : Click on the interface,according to the words as shown in following picture it means the writing has finished.  #### ****5.2.4 RTD Scheme**** Main chip : RTD2674S Memorizer : MX25L3205 Board type : 715G3934-M03-000-004F  Back-up outline : Set the VGA line order manually → Choose the chip type → Read → Write **Reading:** Step 1 : Connect the programmer VGA IS port with the board by VGA line correctly and supply the power,open the software to the main interface,like following picture,set the VGA line orders;  Step 2 : Input the type ”RTD_DRAGON_SPI #ISP” in the “Enter Chip Printing” on the software main interface;  Step 3 : Click on the software interface,operate according to the hint;  Step 4 : Clickto save the file after finishing reading.Try the best to name the file in detail,including the manufacturer,board number,screen type,main chip type,memorizer type for the convenient use in the later.  **Writing:** The writing method : Set the VGA line orders by hand → Select the chip type → Open the file → Write Step 1 : The same as above; Step 2 : The same as above; Step 3 : Clickon the interface and choose the file waiting for being written;  Step 4 : Clickon the interface,according to the words as shown in following picture it means the writing has finished.  #### ****5.2.5 EMMC_ISP Reading and Writing Tutorial**** Board model:Skyworth coocaa 8A13   Step 1 : In order to stop the main chip working (power supply,clock,restoration),the easiest way is crystal oscillator, ground the 2 pins of the crystal oscillator X0R2(beside the shielded wire extension cord) of the main chip;  Step 2 : Find a few key pin test points DO,CMD,CLK,GND,at least 4 lines,and the line should be better within 10cm.   Step 3 : EMMC uses the power supply of board by self,so one line less,just need to supply the 12V power to the board.  Step 4 : Supply the 12V power to the Liquid Crystal mainboard,open the software of the programmer,choose EMMC_AUTO_ISP and then click ”Read”.  The method of EMMC_AUTO to fly ISP line to write please refer to the EMMC offline writing method. EMMC_AUTO_ISP flying line read-writing must stop the main chip working,then the efficiency of read-writing can be high. The way includes : Stop the power supply,short sub the 2 pins of main chip crystal oscillator to the ground,supply the power to the reset pin to force to reset. The easiest way is to short sub the 2 pins of main chip crystal oscillator to the ground,use the original power supply,the voltage of the VCCIO is the same as the EMMC power supply,fly 4 lines (CLK/CMD/D0/GND) to write. #### **5.2.6 On-line Reading IT85XX Series Laptop EC Chip** Wiring diagram(Provide the FPC line and socket : three kinds of separation distance:1mm,0.5mm,0.8mm,the FPC socket is 32pin connected down,FPC line is 24pin with the same direction,also can cut out the 32pin line into 24pin to be used) Important instruction: 1.Don’t forget to connect the GND,don’t forget to connect the ground,the ground line can not be too slim; 2.The FPC line must be cut and plug as requested,then we can see the clipping and connection in the following high-definition wiring diagram,which must be clear; 3.For the IT8586/IT8587 chip,if it can’t enter the ISP mode,please fly the NO.100 pin of chip to GND(The NO.100 pin must be low level).But it don’t need to fly line if it uses the switch board of V1.5 type; 4.Must not plug in when selecting the type and setting the line orders,can only after finishing the setting and click “read” or “write”; 5.When there are some board can not be connected,please turn off and plug in again,this kind of chip aims to catch the ISP ENTER signal when supply electricity. 6.If it still can’t be connected,please check for the line order you want in the （） in the software of programmer,but if there is no the line order you want you can add the line order by yourself.  Laptop mainboard : Lenovo Y400,Board LA8691P,EC type IT8580. The other types like IT8586E，IT8586G，IT8585E,IT8587E and so on of TQFP128和BGA footprint EC,the reading and writing way:
