Lenovo Phones / Tablets Test Points (TP) Here
 

Test Point (Eng. Test points - the key point) - points on the board mobile phone, making it possible to record the phone's memory (usually in the boot area) information in the event of software or hardware errors.

TA should be sought only if the PC does not react to connect a standard USB cable, you turn off the phone!

Type Of TP
----------------------------
All TP can be divided into types of following items:

1. Caused by a combination of buttons, ie not requiring disassembly tf.apparata. It should be noted that Lenovo is one of the few that is on most of its devices makes this option (info on 2014)
2. Caused by the closure of certain control points (KT) on board the phone or its components
3. Caused by the closure of certain Pin Phone
4. Caused by opening of certain CT or phone lines on the board or its components. I note that this is the most difficult and inconvenient option
5. Well, the worst option - the lack of TP in this case will only desoldering memory chips and programming on the programmer
6. If there is a "box" (they tuevahucha) can pour through firmware. Because not cheap price (approx 200ue), they are mainly used in the SC.

!!! This topic will be discussed options 1, 2, 3, and (*** forbid) 4 !!!

TP combination of buttons
-----------------------------
P700 hold "Volume + and -" to insert the battery, connect
P770 Sandwiched "Volume +"
P780 USB when connected to press Reset
S850 Sandwiched "Volume +"
T2-A7-10F Sandwiched "Volume +"


Search TP
------------------------------
1- The combination of buttons

1. Start the "Device Manager" ("Control") on the PC
2. OFF yuchit unit, insert the cord USB
3. Tighten the button "Volume +" on the unit and connect the other end to your PC (the button "Volume + "is most often used for TA devices Lenovo)
4. In the" control "is likely to appear for a device (with Voskl. sign), RMB clicking on it (prav.knop.myshi) Choose Properties and tab information in listed property, selecthardware ID, and look what's pid if there is something like USB \ VID_0E8D & PID_0003 ie pid = 0003 - you were lucky you found "button TP"
5. Install the driver as the same as for the firmware will only driver with a different name probably - "MediaTek USB Port"------If the same pid will be USB \ Vid_0e8d & Pid_2000 means to call this combination of driver preloader probable name - "MediaTek PreLoader USB VCOM Port". Then we must continue to search for other TP buttons and combinations of buttons (peredёrgivaya CRA), as well as being check all other available options: with battery taken out, with the push of a button "Reset", etc.Those. repeating steps 3 and 4 to the other options.There was an incident (tf. I do not remember but not Lenovo) - people going on a serious torture tf and my advice tried every combination of buttons, but Pid_0003 and was not found (((He was not stopped and started bullying, which resulted in the (for zaparke) fully formatted memory. FT naturally stopped seeing tf. but there was "unbelievable" after ubivstva preloader on one combination became determined Pid_0003. It is clear that the firmware has been fully restored (backup was nvram).Conclusion - Hope dies last!

2- CT circuit
This option is only used when it is not working or not B.1The principle is as follows. In the off tf through ballast resistor 800-1000 ohms closes a certain point on the ground (minus food) or less two points together. !!! Warning, you can not close the point without a resistor - TF will burn if the supply line loop ends with "weight". Thus Tp is translated into a special mode which does not require a loader apparatus. When you connect your phone to the PC with the TA will be found with the equipment PID_0003 see above var.1 if so then install the driver if nothing had happened and found a device with a different pid then try another point.
For greater simplicity, it is recommended to open the "Device Manager" and turn the sound on your PC.
So it is possible to use the program USBdeview that show was, whether the device is connected with the correct pid if you do not have time to notice. USB_dev.rar 198,11K186 times Downloadedhttp://lenovo-forums.ru/public/style..._types/zip.gif
