Hi! Does anyone know if this phone has exposed UART or JTAG on the PCB? I'm looking to do some low-level debugging.

Hi all,
I am new to this thread..
I am actually trying to make my mini pro sk17i compatible with QXDM as is has got qualcomm chipset, for which modem and diagnostic port need to be enabled.
I have already rooted my phone and modified USBmodetable.sh to enable modem, diagnostic and NMEA port.
My phone is working fine..no issues with that..
however, when I check the device manager, under other devices there are 3 SEMC HSUSB devices..I am assuming it to be for modem, diagnostic and NMEA port..
Now, i have searched many threads and ports to get the drivers for the above mentioned ports...still no luck..
I am using th phone in USB debugging and enable unknown sources..and working on vista..
Could any one please suggest me!!
i flashed my phone and the imei got invalid after that. i saw some tutorial on web for that using "QPST" software but i am not able to connect the phone as usb virtual serial port that is the usb com port. can anyone help me out with that ?
i am trying to do some changes using the qualcomm tool QPST for that i need to connect the phone as USB SERIAL PORT (COM PORT) . do anyone have an idea how do that ?
please go through this post and try it out. it has procedure to connect your phone to QXDM which should work with QPST too.

i just hard brick my phone and moreover, i've broken my LCD-touchscreen.
I unbrick my phone by flash tool, but now i can't do anything because the screen has damaged. Is there any tool that i can use to reproduce the screen on my pc? Because of i reinstall the stock software so i don't have usb debug enabled, and i can't use ADB commands. Is there any way to by pass usb debug to use and configure my phone by pc?
Does anyone know where the uart is located on this device and how I can tap into it?
I need to do some kernel debugging and from the CM kernel commit log I can tell they enabled it in the kernel, but I simply can't find any documentation on where the physical connectors are located.

You get a serial port when you are flashing with qpst if thats of any help. When phone is turned off, you hold vol + and then insert usb cable and the phone will be in a modem diag flash mode something for like 5sec and if there hasnt been any activity from the connected pc then it will continue booting. Was quite a hassle to flash original zui through qpst I tell you but thats the only time ive seen a serial comport from the phone in device manager.
You might already know this and im sry if its a dumb answer.
While the Qualcomm Loader mode is technically a USB serial port, this is not what I'm searching for.
I talk about the kernel debugging serial port used for outputting kernel messages.
