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.

External antenna ipaq hx4700

Connected external antenna to ipaq hx4700. Antenna was from a Belkin Mimo router that had the right size connector (very small IPX connector)
First removed existing connector/wire on wifi board that leads to onboard antenna, then connected external antenna wire to board.
Antenna was omni-directional so there was not much difference in signal. Might try making a directional parabola to fit around the rubber ducky and test with mini stumbler.

DIY BGA RAM upgrade...hmm, now where did I put that toaster oven.

That Chinese site "translation" says:
The ninth step, the new memory chips placed on the chip welding position, alignment solder joints, is very simple, because the chip is surrounded by a white frame, as long as the alignment position on the list.

I'm surprised how much space there is btw the spots on the BGA chips.
I wish I had a rework station. Has anybody else tried this? I know about PPCtechs, I'm talking DIY.

Glad to hear you're using this: I plan to keep it much more aggressively up-to-date than has been the case in the past, but don't hesitate to let me know if you find errors or need clarifications.

Sorry maybe I misunderstand, are you Yanzeyuan? If so, great write up over there! I wish I could read Chinese.
Welcome to xda-dev!

If anyone's interested, I found an excellent site with alot links to technical info on the hx4700. It's in Czech so Google translate. Links to chips, antenna, etc. Best tech info on 4700 I've found so far.

nice!!!!
tnks

Very nice but I hope never to need it

Thank you, i intend to replace my front cover.

i think you shoud wait... i have removed the old front cover and now i have touch problems(i press certain area and the phone rigesters another area) don't know what to do??
i believe that my phone is out of warranty now.
if any one knows where the problem is please help!

the phone is now back from the repair center ... they have replaced the whole screen with touch ... it had cost me a lot of money "about 500 LE" and the phone now isn't the same as it was before this ... so i don't recommend any one of you to do this without being completely careful ...
now my phone is out of warranty ... and i have to pay extra money to revert it back to it's original case ... so BE CAREFUL with what you are doing as this is not easy as it seems to be.

Yes I fu**ed up mine too. First it was some indentation on the front upper rim, then the camera lens cover, so I decided I was up to a DIY work. I've often refurbished my dear SE phones to look as new but this level four repair has proven to be beyond my reach. The local service co. returned the phone in the same state and said no can do.
T'is the time I had to admit I really love this crappy piece of software on a wonderfully sweet hardware and have to get another one back, as price dropped as low as its makers dropped the phone itself.
Next SE X2 I will lay my hands on will have all my TLC and probably end up years from now as a stylish portable FM radio player, aside to an old R520m I use as the ultimate alarm clock with light sensor snooze.

thank for share

thanks for sharing

thanks very good

[Q] Before I pulverize my Jade...

Hello friends,
I've been using this phone for two years now and it was not bad until recently when touch screen started to misfunction, especially in lower third of the screen, making it impossible to type meny buttons and use keyboard correctly. Since then, I have properly flashed several ROMs, even cooked ones from this forum (btw, I find them very neat) but the problem persist in wide range:
- with some ROMs it get stucked on Screen alignment;
- even if "Remote Screen Alignment" tool was used, it didnt' help with most ROMs;
- Some ROMs like
_HTC Touch 3G_RUU_Jade_Orange_FR-B2B_1.71.73.11_Radio_Sign_12.36.30.29.UMA_0.29.30.U23_Ship
and
sj1.2.2-wwe_ultralite&clean (thanks to developers and uploaders)
pass well the screen alignment, but after short walk through Menu it starts again to be unprecise and makes use of keyboard and other impossible!!!
So, just before I grab my hammer and pulverize this dear and beloved Windows phone, is there ANYONE who can give me an advice here?
Thanks to all of you and keep developing, because you're doing a great deed for the people worldwide.
Cheers from France

Mais oui, mon ami. The problem lies with the digitizer, meaning the device which converts your screen touches to digital information. It's the phone's plastic screen cover, to be more precise. Either take your phone to a GSM service to have yours replaced, or buy a new one from e-bay and change it yourself, if you're a DIY kind of guy.
This is how the digitizer looks:

Multumesc prietenului meu!
I thought it could be a hardware failure, because we just can't blame it on software every time.
Funny, but I think I didn't wear-out this digitizer that much in the past, but maybe their lifetime is not as long as three years?
I remember this Jade fell of the table once, so maybe it could be some bad connection?
I also took your advice and googled a bit for shopping results and it seems that there are TWO different sorts of displays and digitizers for the same model of HTC Touch 3G Jade T3232. This means that I should open up the phone prior to purchase of this spare part.
I promise to post here the result of this "surgical operation" once I get it done.
Thanks again

Real Analog RGB output on PDA and fully configurable resolutions (pictures inside)

Hello,
These days I have managed to add real analog video output to my Asus P750. My goal is to connect the pda to my car's navi screen. It has 400x234 res. (NTSC timings).
HARDWARE PART:
I desolder the small LCD FFC connector located on the pda board, and solder ultra fine cable leads to the small pads:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then, I solder this leads to a PCB I have designed months ago with ADV7125 DAC, to make some test before design the final PCB:
This is my car navi screen, it receives analog RGB input:
SOFTWARE PART:
I have built some Windows CE images for PXA270 development platforms, and I have one LCD DLL driver, from Toradex, that is able to make configurable all timings parameters through registry:
http://wiki.toradex.com/index.php/Display_driver_registry_settings
The user of this forum, pupakota (thanks again), helped me. He took the file, and insert it into the Windos mobile 6.1 ROM using something called "kitchen".
Then, I flashed my Asus with the modified rom, leave it to start, and connect to my pc using activesync. With RegEditor, I added the correct config into registry, and new DLL took this config after reset, result? Windows mobile 6.1 400x234 15.7khz 60hz:
(Colors are bad, clock valid edge stuff ... nothing important yet)
BUT, after 10 seconds of the start, it suddenly changes resoluntions and timings to 20.4khz hsync 79Hz vsync:
Please, need software help, what is happening here?? why the SO is "swaping" to another timings 10 seconds after the boot?
Thanks!!!

allright, pm sent, testrom soon. imho, cpu driver's getting into way(it may change lcd timings;/).
check cpu settings on all possible modes(avoid auto).
shame i cannot be there, i think i could help much faster then..
