Hello,
How find test point Kcolo and gnd on the motherboard jiayu s3
thank you
I don't know about test pint Kcolo but I guess that the ground is common so if you simple use the ground on you'r battery connection should be fine.

Subj. Does anybody research the JTAG way?
I have an information what pins on PXA272 are JTAG interface. But I don't know where it's pins traced out on mainboard. The separation of PXA272 from mainboard is impossible in my case(for a while).
Does anybody know JTAG pins on mainboard for ATOM?
What tools for PC can support JTAG? Can I make a LPT-device for the connection PDA to PC by JTAG?
Did you find jtag pimout yet ? I have the same problem as yours, dead atom !
Basicly, I've seen couple connector in PDA which I believe are JTAG pinout, I've seen it in ETEN and in Atom it seem placed near the simcard holder. You'll see eight gold circle contact on the PCB, I believe six of them are JTAG pinout.
But still can't find the info about those specific pinout.
Still find the soft, mostly run under linux needed in win
I guess JTAG is my only option for waking up my atom, so if you have any info regarding this matter, would you please share with me ??
Thank you

Click to expand...
Click to collapse
How on earth did you manage to get into the wire?
Anyway, just re-assemble your phone and make claim on your insurance
It´s happened while disassembling.
It´s reassembled back again and everything is working fine now after falling into swimming pool but just the coaxial cable inside is missing. I can choose now using the one for wifi or for gps.
Now it´s connected to wifi, more important for me.
But I am still needing a coaxial cable to connect GPS!
Please help!
anyone found this cable yet?
Hi,
i found some pins on my mobile phone that mostlikely will be some jtag pins
(since i found serial already).
Now hard part is to find what pin is jtag and what not.
I am not seem to be able to find information how i can eliminate pins.
Does anyone of you have any tips or howto´s?
ps desoldering mt fpga cpu is not an option
thanks!
No-one?
Common guys (&girls) !
I remember it here as the forum to get such help or information!
I am sure plenty of you guys should have experiences with jtag´ing
mobile devices!
Maybe i did not post enough information;
it has an arm s3c6410 (pins are hidden under the fpga),
so i know it has jtag and serial debug (witch i found).
My device has +-22 pins around the simholder that are reachable and show some reading while testing voltages , a few of them should be jtag since there are no other testpins on the pcb..
So if any of you could point me to a howto or
explains how to find some important pin(s) i think i can manage it.
hi I need the x10 pcb schematic. Thank's
I don't think they release the pcb schematic of any smartphone. Why do you need it?
I need it to repair communication. I've already made a charging work but I don't know how to fix communication
Hi all, new to XDa so go easy on me here...
Just. Got a smj327p sprint phone
Where I live I get very poor 4g coverage roughly -105dbm on band 41
What I am trying to do is connect an external antenna
The phone has a mhc705 connector labeled r1 which I'd love to make use of
I have a patch lead from my S4 days, This is a ms705 to FME
The cable fits the port but I do not think the center pin is making contact as I do not get any signal changes whatsoever, doesn't appear long enough
I am trying to avoid using a passive patch
can someone recommend a correct cable for this phone?
Thanks in advance
Hey Jer1981,
I'm in the same condition, pls update if you find a solution to plug an external antenna to the J3.
I share here a reply from some antenna makers in New Zealand: "The port on the J3 is more of a 'test port' than a usable antenna port. The port is smaller and more delicate than the one in the link, so much so it's designed for use in a 'laboratory environment' only. I can get the fitting to work with it, but it must be held in place and costs more."
I'm thinking of getting a 3G mobile wifi device from huawei with external antenna port...
Hi what cable are you using? for this as mine doesn't appear to get a connection at all
