Hello,
I need some assistance with a hardware issue with my IPAQ 2490b.
About a year ago I had to replace the display of my IPAQ 2490b, but during the procedure I broke two components on the motherboard that I suppose are responsible for the USB connection to the computer. Since then my IPAQ is not recognized by a PC nor does it do charging through the USB. This wasn't really a big issue since now, because I did most of my syncing through BT, however with the aging WM5 I would like to be able to use on of the WM6 roms that we have around, however for that I need my USB connection.
I searched the net for a schematic of the IPAQ device, but I wasn't able to find one. I took some pictures of the components that are broken on my IPAQ 2490b mobo, so would somebody be so kind to tell me if he either knows or could find out, what are those, so I can replace them.
Thank you in advance for the help.
I have this model.
From your picture I think it is capacitor or resistor.
I will check and tell to you.
Isn't anyone else willing to help?
I am still looking for a solution. If someone is able to help, please do.
I hate doing this, but I just wanted to bump the topic, hoping that someone might help me. Please?! Pretty please !

Hello Universalowners!
I got a really big Problem. My Universal falled down 4 month ago. Because of that the USB-Connector broke out. Till yesterday that was no problem. My Universal worked pretty good. Under Windows, I was able to connect to my device by Bluetooth.
No here comes my problem.
Yesterday I booted up my device and I dont know why, it came up in bootloader mode.
I tried every key combination, but it does not reboot back to windows. Even Both softkey+reset does not work.
My friend owns an universal too, and we tried to back up his rom to sd card with mtty. The d2s command is locked on his device. There is no chance to backup his rom to sd card.
That would be my only chance to get my universal back to life.
The change of the usb connector would cost me a lot Euros.
I really don´t need the usb connection if I have a running system.
I charge my batteries by an external device and everything else I can do by bluetooth or infrared.
So please tell me, what I can do, to get my problem solved. I heared something about the tool itsutils.exe with rapi enabler on my friends device. But I really do not know, how I have to handle this.
Could someone send me the image, which I can write to sdcard with my laptop?? Please help me. I need my universal like the air to live!
Hope I will get a soon answer from you!! Thank you in advance!!!!!!
Don't o2 Germany do an insurance plan like o2 UK?
If I were you I'd buy the connector for the Euro or so it will cost, and solder it in myself. But of course, if it goes wrong you'll have fried your XDA with no backup. Can't you just call o2, take out insurance, then about a month later, "Lose" it?
Hello, does someone have the jtag pinout for the uni?
Or at least the circuit diagram...
I thought the whole point of jtag was that it was a standardised interface connector:
http://www.interfacebus.com/Design_Connector_JTAG_Bus.html
or am I misunderstanding your question?
Cheers,
yes, I know what is jtag but probably my question was misplaced.
what I would know is where are jtag testpoints on universal.
my phone is bricked and the only hope of resurrection is restore the bootloader through jtag
ah right, I'm with you now. have you checked out the universal reference manual? is it mentioned in there?
-edit- no just checked doesnt appear to have any mention or picture of one.
sadly true: the service manual doesn't mention it.
does someone has got schematics for the universal?
sigh! i'm going to believe that my uni will be forever a nice paperweight...
any news?
Hello, I'm still stuck with my uni bricked. Anyone have new suggestions or jtag pinout?
Thanks!
I payed about 50USD to have my bootloader chip replaced here in China.
cant find any other solution for the same brick here. I'v heard someone here fixed his dead bootloader by jtag DOC reflash.good luck.
Hi champro, then does you have got the bootloader chip replaced and not reflashed?
Does you could contact someone to get jtag pinout for the universal?
Thanks a lot.
Any success for bootloader solutions ? I also have a bricked universal.
Thanks
Still nothing...
Hi, I haven't debricked my uni yet. But in the meantime I'm looking for a dead mainboard (or a whole dead phone) in the way I'll could desolder the cpu to trace the jtag pins. When I'll have this pinout I'll count on the support of this forum to find a pal that will dump a working phone to restore mine.

we are allready doing this no need to break two phones
Great!!!!!!!!
Fantastic! May I participate? I'm a average experienced user with jtag interfaces and a dead M5000 to work on!
Please is a lot of time that I'm waiting for the jtag pinout!
ok Lt.Cmdr.Ivan is going to trace the JTAG points from under the CPU of his dead Universal, last I heard he was about to put it in a toaster to get it off
You say you have JTAG experiance? When we find the points could you work out the best/only method etc to fix a broken Universal
Yes, I've already debricked a toshiba e740 pda last year. A complete success!
The best way to desolder a bga is to use a heater gun like those used to remove paint from walls. It is very cheap 15~20$. If you aim to the motherboard with this gun, surface mounted components literally fly away or fall down if is it in vertical position.
I'll wait anxiously for news!!!
i suppose who can afford a digital multimeter, can afford a hot-air soldering station as well. (well under $100 now)
anyway, you can just use a 300W infrared bulb and several hours and the work is done as well.
just pick off the plastic items before applying this heat.
Hi, any news? The number of bricked universal is growing!!!
roglioWhat software you used and what adapter LPT (wigler )or another?
If you know the points jtag as you will write in DOC (DiskOnChip) SPL and IPL ?
Just fyi progress ont he JTAG project can be found here:
The Universal JTAG Project
We found them
After trying all types of tricks, I am still unable to get my USB port on the Artemis to do anything but charge the phone. I am dying to stick a Tom_codon firmware on the thing but without a USB port I am pretty much dead in the water. Anyone have any experience with PPC Techs repair service? They seem like they are pretty fast at turnaround time. I am curious how much a mini-USB port repair might cost. Don't they just open the case, de-solder old port, solder in a new one, close it and run some diagnostics or does it go deeper than that?
Any experience or pricing info for this type of repair would be appreciated. Thanks!
Really wish we had some news on the HTC Polaris...might be vaporware!
Dubhead
No one has ever used PPC Techs??
Looks like everyone has a perfectly functional Artemis all the time?! I would love to get mine repaired if it is worthwhile, especially since the WM6 upgrade is out from HTC. Anyways, please weigh in with your thoughts/experiences in getting a repair done either from PPC Techs or HTC themselves. Thanks!

Hi,
my Problem is exactly the same. But I cant send it to t-mobile because i've flashed an WM6 for O2 and without USB I can't update to the original German T-Mobile ROM.
Greetings
Ali
I had a minor probelm with the USB connector where the headphones would crack and splutter on playback.
I used some good contact cleaner and it seems to have done the trick.

if your device is CID-Unlocked you can flash any rom with micro-sd-card and bootloader. go to wiki

Good morning I have a bricked XDA 02 (HTC Wizard), after a tentative of rom update. Now is dead compleately (doesn't switch on). The only way to solve the problem is the Jtag programming of the processor. I'm looking for the correct JTAG pins, but anyone have traced it till now. I have dismounted the brick and I found a strip on the left side of the board, can anyone tell me what it is used for (picture 2 and 4)??? Can anyone tell me if I can found the JTAG points under the soldering below OMAP processor? Does anyone have the OMAP 850 datasheet? Are the pins close to sim connector useful for what I'm looking for? Thanks to anyone that want to help me...
hi
me and some guys we are working finding that pins for reflashing
join us in thread (dead wizard , never let's revive) to continue it
i attached many important pic in last page , so take a look

Was it really necessary to point to a russian topic?
In the first post I just want to salute all users of this forum and I hope to help me to solve the problem with a HTC P3300 that is dead.
The phone was dead when I get it and I so there is no suffers mechanical shocs or to be damaged by water or something liquid.
When I conect it to a power supply and push power on the device start consuming about 110 mA and just stay in that mode.In other devices the problem was solved by replacing the quartz that gave the tact frequency to CPU or by resoldering the CPU.With this I've made both things but no way to work.If someone had this problem before I just want to tell me how did solve it;where can I found it's diagram schematics or a service manual.Can be this a software problem and possible need to flas it via jtag procedure?
Thanks a lot and I hope to repair it!
After a few hours of work on it I succed to make it working.The problem was from flash chip(resolder it and it's OK).I also find a service manual for it but it's not good(it show how to assembly/dissasembly the device).
All the best!
Hi there..
nice thing if you can make this work...
I have brick of artemis and I think it is software problem..as you said.
is there instruction how to do it?Or how much you charge for it?
cheers

If it's a software problem here are tutorials on how to fix it;if it's hardware You must have have experience to work on this kind of phones.
Good Luck!

Hi!
Could you please give us the tutorials? A friens has bricked his Artemis and I would like to try to bring it back.
