I am going to apologize for this newby question upfront, but in what you said or what you saw, does this phone have the same kind of graphics accelerator that the Dell v50x has? I have seen video and games on the Dell Axim v50x and it is amazing. I was just hoping that the Universal was going to be comparable.

[rick83]

good stuff but, hopefully someone can post the entire thing.. like lcd, keyboard , etc

here they state that it will use the same ati graphic chip as the xdaII
ups my bad that was the device beside it the graphics of the universal was tba.

about graphic chips and games then
having a fancy graphic chip dont mean anything unless the game
is made to take advantage of it
it's not automaticly used

and same thing with the resolution being VGA games have to support it

The ROM files dumped by Asukal
don't include "atihwtbl0.txt", which is
a bad sign.
There is a
[HKEY_LOCAL_MACHINE\Drivers\Display\Active\Built In LCD]
"Dll"="ddi.dll"
"BufferMode"=dword:00000001
"TapMode"=dword:00000001

but i don't see the "ddi.dll", too. That gives some hope.
--------------------------

The GPIO file dumped by Asukal
shows that the LCD and keyboard are
served by the PXA :(

[tintoy]

Interesting to note the date on the PCB is 14th April - was this a engineering sample/pre production sample?

[SiliconS]

Can anyone tell me where the WiFi and Bluetooth antennae are located? What's the best orientation for the device when trying to connect to a weak WiFi signal?

[stot]

The Wifi one ( looking at this pic, and from taking appart mine ) is screwed into the lowest screw hole next to the USB port you see there. The BT antenna is to 1" the right of the 1.3mp camera if you are pointing it at yourself in portrait.

the phone antenna is around the camera lens.

There is ALSO an antenna of some kind at the bottom going across the SD slot, right next to it is a pigtail connector thingy like you get on MiniPCI wireless cards.

[SiliconS]

Cool, thanks stot.

So the WiFi antenna is in the back edge of the device, near the hinge.
The Bluetooth antenna is near the stylus hole.

Useful info - cheers!

All the antennae, then, are in the 'base' unit with the keyboard. I guess if signal strength is a problem for WiFi then I should pick it up off the desk and use it in tablet mode rather than laptop mode. :?:

[stot]

yes ALL antenna are in the base unit. Id point the back of the device to the router/access point as much as possible if youre having weak signal. I think in portrait mode your hand is likely to be covering the wifi antenna, if youre right handed.

[hazer]

Thanks for this pics.

I too would like to see the rest of the parts. Specifically the hinge on the screen side.

I unscrewed the keyboard (single screw) side, but the 4 screw on the lid don't remove the metal plate.

It's seems the actual screen housing has to be separated before the metal plate will come out.

Why do I care? I'm wondering if there some way to tighten the pivot point.

Any help would be GREATLY appreciated.

[Capt. Sky]

This is is top-class device, why 520, why not 624mhz!?

[lbendlin]

to have better battery life.

[Capt. Sky]

to have better battery life.

not good enough reason! battery consumption is not so bigger, and there is power&speed management system (axim x50v), and u can adjust device to best perfomance or batt saving.....

[lbendlin]

go ahead, use Pocket Mechanic...

[Nossie]

can anyone confirm the graphics memory? :-|

[Flavio]

Is there any way to increase the Storage Memory on the Universal?
I had to install all my programs to the SD card to avoid repeating critical memory messages. is Storage Memory RAM or ROM?

[peter_altherr]

hello itsme and other hardware gurus,

first i like to thank you for providing such detailed hardware information for the xda wiki. after studying all those infos i would like to initiate a discussion about those two empty places on the pcb located nearby the m-systems doc g3 chip. when i compare the layout of the soldering points (shape and quantity) against the informations in the data sheet of infineons dram-chips and m-system doc chips i am almost sure that those two reserved spaces are not for expanding the 64mb of ram (which is more than enough from todays point of view) but for expanding flash-rom (main memory or storage) by one or two m-systems doc chips with 64mb each in a 7x10 fbga package. that means the device could be upgraded up to 128mb of additional flash rom by soldering two more m-system doc chips on the pcb.

what do you think about that idea?

still unanswered is the question whether there is a software modification required for the universal in order to detect the additional memory or whether this function is already in the current software.


best regards

peter

[xda_guy]

oh it has a qualcomm modem and the 3g protocol stack was done in farnborough, uk?

is the ti tnetw1100bg a wifi chip

i geuss the intel pxa is the media processor

what does this the xilinx cpld 2c128 programmable logic do?

[underwurlde]

@peter_altherr

You'd really, honestly, hand on heart take your pda to a hot air gun & attempt to solder on 2 FBGA ICs - you're bloody mad mate! :wink:

Strong piece of advice - don't even think about doing this!!!!!!

If this tought did by some miracle enter therein, take your mind firmly off it by looking at some nice pictures of some ice cold pints of beer freely available on the 'net.

The wireless chip seems to support 11g, but specifications for the Qtek 9000 claim that only 11b is supported.

What am I missing? I have obviously misunderstood something, right?

EDIT:

I was finally able to find threads that discussed a registry hack to turn on G support.

Hmm .. from what i've read it may say G and restrict you to g accesspoints but it still runs at the speed of a b

[colonel]

there is some 3d capability, look at multimedia-graphics below:

http://www.cdmatech.com/docs_details/chip_tool/msm_chip_results.jsp?sSearch=&sQString=&chip=MSM6250#SD%20Card%20interface%20support

wonder whether this has to be written specially for, or is used automatically when 2d graphics calls are received ?

The point isn't to be restricted to G access points. By supporting 11g users of the Qtek 9000 will be able to connect to access points that are configured to only allow G-clients. The speed isn't important.

I have made changes in the registry and get G-access points to appear, but I am unable to connect.

[devGOD]

is it possible to decrease the frequency of the 2100mhz antenna to 1900mhz via a software?

[underwurlde]

99% sure this is certainly hardware fixed @2.1GHz.

BTW, Why would you want 1.9GHz???

US is 1.9GHz :(

[alynch75]

Will this phone work on the Cingular Cell Phone netwok in the USA

[lbendlin]

Not on the 850 MHz band, only in areas where they use 1900MHz. Basically this means T-Mobile roaming.

[xda_guy]

Hello

i was wondering if you guys could tell me what is the crystal used on the HTC Universal. i guess there wuld be 2 crystals, one for the real time clock using 23.768 KHz and one for the arm processor, i guess 10 MHz, is that correct?

the schematic of the universal does not show the clock? can some one tell me where it is on this board?

do you guys know what is the make of the lcd screen?

[skywriter]

blah i just dropped my UNIVERSAL, now the screen is loose and wobbly. anyone take theirs apart and try to tighten it? the service manual shows all the steps to take it apart and put it back together. any brave soul attempt it?

edit: awesome! i took the single black screw out on the KB side the the swivel screen and bent the bast plate back. good as new! :) YAY!

[Ferret-Simpson]

The TFT is on the PXA270 FB device. Which of course makes it far easier to get linux on it. XD

Which it did have a graphics coprocessor though, it'd speed snes9x up somewhat.

[eddiept]

Does anybody knows the Wifi antenna Gain in dBi ??

[akibrit]

I have made changes in the registry and get G-access points to appear, but I am unable to connect.

I still couldn´t figure out if it is possible to connect to G acess points? If yes, at what speed?

Thanks;;

[r3bel]

YES you can connect to 802.11g access points.

BUT at 11mbps only

[akibrit]

So they do not put that is WIFI G compatible because it cannot connect at 54Mbps speed....

Interesting...

[claudio19]

hello al
I want to change the case ( I have found spares) but I am quite reluctunt of doing it without any istruction...I have seen someone here talks about a service manual...where is it available? is anyhow any other short form showing how to change disassemble the case?

thanx

[RoHaM]

so theres 2 32mb ram chips... if I get my friends old mda pro(screen smashed and top half broken to a few pieces), take the chips out... can I put em in my xda exec?

and are they soldered in.. that would make getting tem out kinda impossible...

any info would be appreciated

[monti_908]

my universal always showing "insert sim card", tried with may sims, does anybody have any solution.

[ToolmanFedEx]

Will this phone work on the Cingular Cell Phone netwok in the USA

I am using my JasJar on Cingular/ATT. Seems to be be working fine. I guess mine is unlocked, I do not know, but I put my SIM card in it and took it to my local Cingular/ATT store and had them set up the number to call and make sure that it worked properly also with internet access.

Re-do the Unlock SIM Tool ... or else try updating another ROM..finally if that doesnt help talk to a hardware specialist .

[domi007]

Has somebody any information about how to communicate with the small light sensor?

I think, WM controls it, but there must be some kind of gate/API through i can read out the actual value from it ("dark" or "bright" :D:D).
