Possible Revival for a Corrupt Bootloader & a Dead xdaII

Last week I posted a thread titled (Corrupt Bootloader :-( Dead Qtek2020... Need Urgent help...) and Toenailed was kind enough to post a link on that thread that would shed some light on the subject. The link explains how to revive a Wallaby, but our target device is the Himalaya ...

As it seems that by using jtag software it is possible to reflash corrupt bootloaders. Now please pay close attention, if you notice closely, certain diagnostic points have been located on the Wallaby's PCB. These points are then connected to PC's LPT1 port. These points are easily located on the Wallaby since they were printed on the Wallaby's PCB. But nothing is printed on the Himalaya's PCB. The diagnostic points that have been identified on the Wallaby's PCB are (nTRST, TDO, TDI, Vstandby, TMS, TCK, and GND). I'me having great difficulty identifying the corresponding points on the Himalaya's PCB. If anyone here in this Forum has an idea about the location of these diagnostic points on the Himalaya's PCB please post them right away. I've already designed the cable needed to connect the PCB to the PC but got stuck on the locations of these diagnostic points.
This is a shout to all electronic and Himalaya experts, plz help me locate these diagnostic points on the Himalaya's PCB. By doing so, would have helped in bringing alot of dead Himalayas back to life.
Here are two pictures explaining the loacted diagnostic points on the Wallaby's PCB.

Thanks.

Urgent Request ...
Does anyone know HTC's website or e-mail for technical support ??

Come on you guys ....
So you're telling me that no one in this huge forum has any idea about this problem ....

8525 with a missing part

Can someone help me identify the part that is missing from the case of my 8525? If you are looking at the back of the case, the silver cylinder thingy that fits in the opening on the bottom right corner of the case is missing. I'd like to know what this piece does and if I need/should replace it.
TIA for any help!

Mine came the same way from AT&T. I always assumed it was for a Hermes feature AT&T opted not to include in their model, similar to the second camera.

Your stylus is missing
Easy enough to buy another ....

Not the stylus hole... the OTHER side
The stylus fits in the hole on the left side (from the back of the 8525), I'm referring to the hole on the RIGHT side. I believe it is usually covered with a silver circular thing.

That silver ring is nothing more than a place to attach a lanyard to give it it's fancy name. In other words a hook to clip a carrying strap onto if you want one. HTC supply a short wrist lanyard that clips onto the ring - other suppliers I don't know.
You are really not missing anything - with many phones the strap is an optional part.
This sort of thing:

Many thanks Mike (though, secretly I was hoping that it was a missing antenna attachment that would explain why my reception lately has been flakier than a stale croissant)!

You MAY be suffering from the signal flipping from GPRS to 3G. If you get dropped calls and high battery drain, you may want to select GSM Band only in:
Start>Settings>Phone>Band. (Change from Auto to GSM)
(Some branded models do not have this option)
I stress IF you have this problem. BUT it may be worth a try just to see if things improve. If you do not have the option then do a search on Bandswitch or Commmgr.pro

EDIT: By the way there is a place to attach an external aerial under the round rubber pop out cover on the back cover.

3d-printed wide-screen car-holder

Not being able to find a car-holder that would hold my Touch Pro in widescreen
with the keyboard extended firmly and still allow for a power-cable,
I designed this car-holder.
It ataches to anything that can carry a camera (1/4") and to the slide-in car.holders
from HAMA (they sell suction cups, air-hole -attachments, glue-ons and screw-ons).
You can attach the supplied and wider third-party cabless, reach the power-button
and it even comes with a hole to keep yout touch-pen.
If anyone wants one of these,
I can print them for 35eur+postage on my 3D-printer.

Any chance I could get the .stl file? I'd like to use it with my schools 3D printer.

You don´t seem to have that printer for a long time yet to not know http://www.thingiverse.com/
It´s the first place to look for the STL-files of things ment to be printed.

Didn't think to look there. I thought you would've posted a link in here, but oh well.
Thanks!

IGES or STEP
Hi, is it possible to get a IGES or STEP File from you. I want to make one at Work, but from aluminum, with a CNC Mill.
My CAD/CAM Software takes STL files, but import of STL is not the best. It works better with IGES or STEP.
At the moment I am working on a Desktop Dokingstation, its not ready but will be in a short period of time. Will post it here.

Like this?
http://www.thingiverse.com/thing:2195
It´s the original Alibre Design files.
With milling you´d have to work very deep in the material without your toolhead touching the sides
and you certainly have to run multiple faces. I don´t think that will work well.
I´m using my Touch Pro only for development now that I switched to the Nexus One.

I have to say that it pretty cool stuff. Nice work Marcus. What cool times we live in when you can design and fab your own accessories for your phone. Thanks for sharing.

Is there mini pciexpress inside Acer Iconia Tab A500?

Hi all,
I have got an Ericsson F3307G, is there any way to add it into Acer Iconia Tab A500?
thnx

Good question - I don't anyone could answer that without actually cracking open the tablet and having the knowledge to decipher the internals.
Normally, I wouldn't think it would just be a simple, solder it in place and call it a day situation. But, one never knows.

Did you see this guy rip open his? On androidtablets net, post- 13577-whats-under-hood-acer-iconia-tab-a500.html. Sorry I would put up a proper link but I am a newb.
I wonder if that little white strip in middle leftish is an internal sd card?

I have seen a tear down, though I don't know if its that one.
Either way, I'm not knowledgeable enough to know if that would work or not.
Be interesting to find out.

thanks to all for replies. What i search for were internal pictures.
In particular, this:

it should need to solder a mini pciexpress slot on those pins on board (with sim card holder).
this is the thread:
http://www.androidtablets.net/forum...77-whats-under-hood-acer-iconia-tab-a500.html

Yep. That's the image I saw and I doubt it would be just a simple solder job. Why not try it?
EDIT
Besides, it barely looks like it's got any chips on that part of of the PCB and you'd need to add a connector point for the SIM connector to slide into. I think if you got that far, it could very well that the board itself will not accept an after market part like that or that they remove all functionality of that type for wifi models in a future update.

anyway it's bad idea, it's difficult to install beacouse sim card holder will be in wrong direction ti insert sim card if it added :/ the correct way is to buy the a501 version.
thanx to all for your reply and to drive away my dubious

I think the Mainboard is the same for all A5XX model so they just didn't put the
- miniPciE port
- controller O21 and D3 position...
so far I think that will be... risky, not sure to work, and not worth the time to try to SOLDER anything.... sadly.... I was really expected they put the modules functionnal but just not the 3G Card... that will be so nice from ACER...
----- hope the 3G on USB will be ripoff
I heard about some kind of Wifi boxes you put the 3GDongle on it, and all your HomeWifi got internet via 3G.... is that could works?

Replacement I.C
What is the number printed on the dead bug?
It might be a 'house' numbering system used by the Mfr., or it coule be the I.C maker's nuber, such as: LM324, which is a quad op-amp.
Try sourcing from parts suppliers online, such as Mouser, Newark, Phillips, National Semiconductor and so on.
I can try helping you identify the defective component if you can take a pic of the part, showing all markings, then attempt to track down a sutiable part as a replacement/direct drop-in.

I haven't it , I removed IC , phone charge but not show charge Progression on phone screen !
IC is too small can't read what's write on it .
thx

If you already have the schematics, you may find the part number in there.
otherwise compare to THIS post. Otherwise look in:
[GT-N7000][REF] Service Manual + Full Schematics

Thanks @E:V:A this is IC N° SMB328AET
