Hi, I bricked my iPaq hx2795b, and now I have to make a JTAG connector cable, so I can reflash my PXA270 processor. The problem is, that I have absolutely no idea where the JTAG pinouts for this device are!
Can anyone help me with this? On a side note, I could also use help with making the right cable, resistors, luckily I already have a compatible JTAG software.
This may be in the wrong section, sorry for that. Feel free to move if needed.
Can anyone please help me unbrick my device?
Bump.....!!!
Is anyone going to help out..? I seriously need help with this.

Hello,
the bottom connector from my Himalaya is broken...
Does anybody knows if there is a sync-cabel for the back-side connector ?
Or a female plug (perhaps from a cable extension) would help me to solve the problem as well...
Thanks in advance!
I have exactly the same problem. Any advice on where to find that connector. I can't take to a authorized service, because there's none in Macedonia
Thanks
Hey guys, can anyone help please. At least if you can tell me where to find that connector on the internet, so I can change it.
I think it's the same connector as for the IPaq 3800 series, can anyone confirm that. Thanks

go to www.merconline.co.uk for xda2 parts very good for conector repairs
was you finding that cable. I am also searching it, pls tell from where i can get it. i also not sure is it for synch and to charge xda.
cant you charge just the battery on the xda dock?
and sync with bluetooth?
flyboy
but problem is this i cant flash through bluetooth
Exactly same?
I have a Himalaya(i-mate Pocket PC) with a broken USB , repalaced by only a charging port so that I can charge it but cannot flash it! Got the intact cradle though. Is there anyone who can repair my USB port so I can flash it again?
this happenend on My first Himalaya too,i´ve searched a lot through the Net
and couldn´t find any spare parts,what I want to say is...
theres a bigger Problem to find Spare Parts then to solder the Port to the board
(yeahyeah...which isn´t easy too..i know...)
But is there anyone who knows what is the backside connector? And is there cable for it?! It will be good to use it! Just to avoid, soldering and finding spare parts! Any info will be good! I have soldered mini usb 2 times and every time i do that after fall it came of! I'm sick of soldering!!!
MMMMMM That`s it!!!
Look all!!!
The backside connector isn`t for syncornizing an charging!!
It`s just for connecting the "High capacity" battery, you know the big battry with 2400 mAh.
All i want to say, you have to put a new connector to flash roms and charge the battery without take it off from your devices.
Hope i`ve help you with you problem!!!!

I knew that! But if u open a himalaya, and if u see below the back side connector there is a number of small dots, and every single of them are corespondenting for ones where the connector was soldered... So if anyone can find a corespodence for usb connection that will be good project... Just to avoid a use of old and crapy original connector, then u can use any connector u want! (for about 4 pins which is need for charge and usb sync) !!!!

G'day all
I'n need of desperate help as my serial port is stuffed, can someone please tell me if the male part of the connector is available to buy anywhere?
I know this is a tricky soldering job but a good friend has offered to help
Also I notice the rear backpack connector appears to route thru the same pins, does anyone know if this could be used to charge and sinc the phone, and if a connector is available.
Sorry for the gimme questions but I've searched all this site and many more with no luck.
Is it possible?
The dell axim motherboard has
VCC, GND, TDO, TDI, TMS, TRST
I looked on some forums and someone says they might be..
VCC- power
GND- ground
TDO- out
TDI- in- probably what you're looking for
TMS- don't know
TRST- reset, it looks like.
.... Could anyone help with Jtagging? I need a RS232 cable?
Any other thoughts advice?
Thanks
Anyone have any ideas??

the address is:

the language is cheinese, i think you can understand the picture.
my english is poor
hello!
Before writing anything else, i must apologize for my bad English.
A few days ago, i was given a HTC Cruise (Polaris WM6.0), and i was doing tests with it to change the rom. After using pdocwrite, a unknown error occurred in the process, and he was made a brick.
Now i try to revive it by jtag, and in this model, i'm finding an odyssey.
I can not find documentation of polaris and jtag, there is much documentation for jtag and other models, and there is also documentation of riff jtag box, but the riff box price is higher than the htc polaris, and also need the apadtador. Without the adapter i will have the same problem, because is need know which are the pinout
After 20 hours of searching, i located the seven polaris jtag pinout. I now know where is the 7 jtag pinout but do not know which is which, i only know the jtag pinout position.
my question is ... if i have located the 7 jtag pinout, how i can know which is which? TDI, TDO, TCK, TMS, TRST, vcc, gnd and boot pinout.
polaris and xda orbit is the same pcb
Has anyone successfully replaced the USB port on their sensation? If so did you follow a specific guide?
I've read multiple places that the usb port is soldered onto the motherboard itself.

From a teardown video it seems it's as you say - soldered. Though the part is available on Ebay.
However, Attempting repair by yourself is quite risky - unless you know exactly what you are doing (you need to desolder the damaged one, and the solder the new one). Doing this procedure wrong could possibly render your device into an expansive paperweight.
As for a guide - couldn't find one, and if you are not an expert in soldering, I suggest taking it to service to fix it, not worth the risk IMO.
