D-Pad gone crazy!!! - JASJAR, XDA Exec, MDA Pro General

I have a peculiar problem here. My O2 XDA Exec was working fine until one day suddenly the D-Pad/nav-pad UP action started automatically and now it runs continuously . So that no matter which application I run, the UP action is automatically emulated. I simply can't use the device. I have soft reseted , Hard reseted and when all failed upgraded the device to WM6 but the problem is still there. I don't know what the problem is. If it can't be fixed, can I some how disable the D-Pad button? Need help, thanks.

You might have something shorting the contacts, if even a hard-reset didn't remove the error. You might have to take it apart to see the problem, or take it to a repair center(not your provider, they will most probably say the warranty has been voided by the WM6 upgrade) to have it fixed...
Good luck with it!

Thanks for the reply, this is what I was afraid of. It will be difficult to get it repaired at a center because there are not many around who can do it well. Since I donot use the D-Pad that much, disabling it by any registry tweak would do for me for the time being, any suggestion on that. Thanks again.

You'll have to ask someone more knowledgeable than me for that...
the buttons are identified by a seemingly meaningless string in the registry, and god only knows which is "D-pad Up". I'm not sure you can even do such as thing in the registry.
It should be easier to remove the lid, disassemble it, and take a good look inside to see if there's anything in there that shouldn't be. You should be able to see the screws if you turn the lid 90 degrees, and from there, it should be a piece of steak...
Good luck!

Uni D-PAD
Hi, Did you get the uni to the service centre ? did it fix your problem
coz, mine is having the same problem too :-(

JasJar dead!!!HELP PLEASE

HI to everybody....my touchscreen..does not work anymore...I did nothing strange to kill it..i was not working on the JJ...I opened it and nothing happened when i touched the screen with the stylus...so I tried to soft reset it and nothing happened..I hard reset it and nothing...I flashed my rom and nothin'...my screen is not a touchscreen anymore...only keyboard worked and when it asked me to align the screen at the first window i can't do nothing...i'm really desperate I think is not a software trouble but a mechanical ****...and now??does anybody experienced something like that before???thanks for your kind help
mik
Yer dead up Jarjar, jaz jar or however its pronounced! >&
I'm an XDA2i person and am deliberating if I should go for a Universal or not right now....
in your case I'd say it was time to send it back via the place you bought it from ad get a warranty repair. If you have insurance you may want to give them a call and see what they say about replacing it.
Sounds like a hardware fault (theres nothing really 'mechanical' inside these machines) maybe a dodgy connection or dry solder joint etc. I say this because it 'worked' before and 'now isnt working' which means 'something' has changed.
Another alternative would be to find one of the service centre's for PDA's etc and get them to diagnose and fix the problem...
Hope you can get it sorted!
Dennis! West London UK!!
Thanks Dennis...I bought it at expansys..and i really don't know if they have services like that...i'll try to contact them...bah...!!thanks again

Need some Wizard digitizer help, please...!

Hi guys,
I'm having an issue with my digitizer on my 8125. I am wondering if anyone has experienced this, and if anyone knows of any workaround, short of sending the unit back.
After the unit has been great for a month (summiter's 2.17), all of a sudden, when I use the stylus in teh lowe right corner of the screen, it senses the pressure about 3 milimeters to the left.
Therefore, it's almost impossible to use the right scroll bar, if that makes any sense.
I realigned the screen.
It was fine for about 30 minutes.
Same problem.
Reset.
Fine for a bit.
Then same problem.
Now, I bit the bullet, and did a hard reset.
It was running so nicely, but I had no choice.
The digitizer was fine for about 30 minutes.
I was pretty happy...
And now... SAME problem.
Only in the bottom right of the screen, like usual.
Has anyone heard of this?
AFTER a hard reset, before installing apps???
If you think there is a solution, please let me know.
If it's a case of back-to-Cingular... So be it..
...but I figured i would ask the pros before sending it in!
Thanks!
Mike
I have the same problem, though I haven't managed to do a hard reset yet. (Does anybody know how to back up text messages without using an all in one backup program, because I want to rebuild anyway)??
My screen seems to be okay for a period (so far the max has been two weeks) then it becomes unusable after eg. 30 mins. In periods when this happens, it does so up to 10 times a day! Arggg.
I wanted to send it back under warranty, but now the problem has stopped!
Was going to do a hard reset to ensure it's not any dodgy software that I've uninstalled since it was last doing it etc... but I really don't want to lose my texts!
Any help with backing up SMS messages (without restoring full backup thus recreating digitizer problem) appreciated!
Mat
Thanks for the reply!
I was also CERTAIN it was software related, too.
I could NOT believe that after a hard reset, back to square one, that after 30 minutes, again it would be off.
Made no sense to me.
And only in one quarter of the screen.
So far, today, it's been fine.
It's the weirdest thing.
As for backing up your stuff, I have no idea how, sorry.
I'd love to hear any more opinions/ideas...!
Thanks!
I'm also having this issue...hoped the new ROM would fix the issue but noticed it after I installed a few apps....forgot to check it again before installing a few apps (i.e. pocket plus, tcpmp, a2dp cab, etc.)...did you guys end up sending yours back for a replacement or did you find it to be software related? I called Cingular today and HTC and they both were zero help... trying to figure out if I should send it back.... any suggestions are appreciated
I have this issue also... on all ROMs that I put on... There's a thread that says all you need to do is open up to the keyboard and then close to fix.

I found the issue to start after a week, starting on the right hand side, and then moving towards the centre of the screen. Happens all the time now.
Voda v1605 S/N - 626
Somebody with the problem needs to disassemble their TyTN and power it up with the front cover completely removed and the digitizer assy loose. If there's a mechanical issue based on the gaskets or some other case ideoysncracy, the alignment issues will immediately disappear. If my TyTN starts acting up I'll do this myself. We need to divide this problem to conquer it by answering this first all-important question:
Is it Hardware, Software or a combination of both?
HTC's own repair kit tends to indicate that its hardware and that the above test will resolve any issues. However, there have been reports that software changes solve it too and these are backed up by a compelling video that shows a person tapping on the same spot of the kbd SIP and sometimes it would register the correct key and sometimes it would register the key to the right of the one tapped. If the problem were hardware, this wouldn't happen; the offset tap registration would happen consistantly.
Sleuth255, unfortunately it is a hardware issue.
HTC is replacing faulty units and repairing (changing the LCD) if you don't have the original box.

I partially concur. Here is the video that I referred to earlier which, after closer examination, has made me change my opinion as to its root cause:
http://www.youtube.com/watch?v=FQIVv4b2jOI
(notice how his alternating finger pressure on the right side of the case is causing the alignment to shift right by one char).
Nevertheless, I still see posts such as this one which point to a software related cause as well:
mcalbala said:
I had the alignment issue, and the phone started to slow down, I bit the bullet and reimaged the phone (clear memory and reset to factory default), reinstalled software and resynced, and the problem went away totally - seems to be part of the software for the Tytn - Good that it doesnt seem to be hardware related

Maybe there's two completely different issues that are being tied together here.
save yourselves the headache and send it for replcement ...!!
:roll:
@sectorlord: I'd say hard reset first and run for a day w/o re-installing any software. If alignment problem re-surfaces, send it in because you've got the hardware problem that HTC has identified.
Why be without your TyTN if its not hardware? Remember: I'm not disagreeing with the hardware hypothesis here. It's obvious that one cause of screen alignment problems is digitizer/case related. What I'm saying here that there may be two seperate issues here, both of whose effect are screen alignment issues. If this is true, posters following the "just send it in" rationale who actually have the second software related issue, will be sorely disappointed when they get their TyTN back after an indeterminate wait based on regional service differences because the problem will crop right back up after they restore from backup.
I myself can't ignore data just because it doesn't fit the model. Calling this problem solely hardware ignores the data that I posted above from mcalbala as well as countless other posters who have reported similar success from hard resets.
I guess I'll just have to wait for that first post from someone who sent their TyTN in for the fix only to have the problem crop back up to see if my "two problem" hypothesis is correct.
I agree with you... I know some people have success getting rid of the issue by :
1) Hard reset
2) Upgarding ROMs
3) Loosening up the screws
4) Offsetting the calibrations
5) Unticking the USB-PC options
etc ..etc..
I tried all of these, and my unit improves but never totally fixed. I am trying to save you the headache I got.. if you can swap it..do it !
I returned my Trion, and bought a new Dopod838pro WWE HT636XXXX yesterday...
Knock on wood... It's a gamble on my part. I just trust Dopod HK, that they will release these units when this issue is resolved, and they release it last Thursday starting with HT636XXXX.
Is it fixed...I dont know... but surely I will be screaming on SIS if not..
:twisted:
Few days ago I received my repaired tytn back. SN HT627.
According to the serviceburo it should now be repaired according to the instruction of HTC.
parts used:
1x Gasket, Keypad.Apache For.
1x MYLAR,LCM CONN, BREEZE FOR
So, hopefully this really solved the problem.
Regards,
Piet

Reopening the question: A week ago suddenly the notorious screen alignment problem appeared on my device. Never had it before, now every 2 hours, sometimes after 10 minutes already. In my case the SA-problem has several appearences: one time it misallignes a bit to the right, the other time a far end to the left. But always in horizontal line. B.t.w.: in landscape mode the alignment problem always was gone!
So finally after trying everything I knew (from XDA) I did a hardreset with the intention to send it back for repair. But now after the hardreset my SA-problem seems to be gone! I'm testing for hours now, do everything what might cause the problem but nothing (till so far). I only installed TomTom 6 after the hardreset...
Could this be software (programs or settings) cause after all?

keyboard button problem (not symbols)

I was wondering if anyone else is having problems with individual keys wearing out on the 6800. Three of my keys have become a little difficult to use. When I press them they act as if they have not been pressed. I have to press the many times before they will work.
I've tried googling but the only problem people seem to be having is the "symbol problem". My problem is different from this - it is a mechanical problem. The phone is only 6 months old and I use it regularly but not excessively.
I'm thought about taking the phone apart to see if there is anything that I can do.
I have the exact same issue, mostly with the space bar... some keys would take pushing it several before it works or sometimes I would press the key once and I get two letters, for example if I press E once I get EE.
Let me know if you find a solution for this, it's extremely annoying.
sounds like normal wear and tear to me. if you use a button alot, eventually its going to start working less efficiently than it used to. there are a bunch of good (free) full screen keyboards that you can use to give your keyboard a rest. taking apart your phone is a really bad idea. if you've only had it for 6 months, its still under 1 yr manufacturer warranty. send it in and get a new one.
thanks so much for the quick response, this might be a stupid question, but how do I exchange my phone? It's a Sprint Mogul.
probably the most direct way is to head into a Sprint store. and try your best to talk to them like you know what youre talking about, so they dont try to jerk you around. when i was using the xv6700, i got 9.. yes 9 replacement phones on my manufacturers warranty. if there is nothing to show that YOU have damaged the keys, they have to replace the phone for you.
try this, it fixed my key misses and repeats, but i have to hit the keys a bit harder.
Unfortunately, 'titan_key.cab' does not fix my problem

Thanks for the file...unfortunately, the problem persists on my Mogul.
Has anyone found a solution that makes the hardware keyboard perform as it did BEFORE the last official ROM upgrade was released into the wild. Installation of that [allegedly] tested and approved HTC/Sprint file coincided with my beginning to experience my KB problems.

Questions and Answers Section for BA Forum. Post Your Questions Here.

@All,
As a celebration for my 1000th post, I decided to open a new thread based on Tweakman's idea, which seemed to work very well in the Development and Hacking Section. The idea is simple, a single thread for all Questions, Problems, and Concerns regarding Blue Angel. This includes, but it is not limited to:
[highlight]*Problems with Flashing.[/highlight]
Can't get your device in bootloader? Did it freeze during flashing and now it doesn't get past the 4 colored screen? Are you a complete noob and need some guidance as to how to flash? Etc.
[highlight]*Have questions about which Rom is best?[/highlight]
[highlight]*Want to install software but don't know if it is compatible with your BA[/highlight]
You get my point. All the questions that I have seen/answered over the past couple of months are just repetitions of posts, threads, and things that are readily available on the wiki or in other threads. However, people are either lazy, don't know what a Wiki is / where to find it, or just flat out don't know how to search (or read the forum rules for that matter). Having something general (in this case a sticky) that says "Hey, if you have a question, you can ask here" should draw enough attention and start minimizing the number of new threads and posts opened by users (both new and seasoned). This way, we will be able to keep the development threads a little cleaner and smaller... hence making the site's search function work a little better in the process.
@Seniors,
Kinda like the Q&A team, I will need your help in trying to keep the influx of questions to a certain level by answering them as we see them. None of us are logged in 24/7 (or at least some of us aren't ), but if you guys see a question, please try to answer it. I know that xplode, Chef_Tony, markanthonypr, red_hanks, sun_dream, imatrix, +Que_PPC, motisu, and others normally try to keep this under control, but if we centralize it and contain it, we will have a cleaner forum.
Reserved for future use.

this is strange issued problems but in mine (BA) every thing is ok,this problems only in my friend (BA),I mate PDA2K.
any ideas?any suggestions?

Hey homam,
Thanks for kicking things off
First of all, which OS were you having problems with? This is important because it could have been a bug in a rom that could have been fixed in a later version.
@mark,
I know I can count on you, buddy I need help from the mods as well though. I cannot redirect posts to here and/or close threads
My BA, keeps turning on from standby, by a light shock! I maen, if you press the Power button, and then you knock gently on it's back, it turns back on!!
I've set to "Lock all buttons except the power button", However, I still have this issue.
Well, I must confess that once it dropped off of my hand, and it's the result of that...
Any ideas?
by "it turns back on" i assume you mean it wakes up from stand by, it doesn't really start like after a soft reset, right?
since the BA's only battery activated wake-up is in the cradle and we are not talking about soft reset, my first guess is, the battery is not to blame.
have you checked whether you can use your camera at all time? i mean, the camera_detect does not usually run at all times but if the camera connector is a little lose, from now and then it could "discover" the new camera hardware and wake up, that is unlikely for normal devices, but if yours had a crash before...
you could refer to this site for checking possible hardware reasons:
http://www.land-of-kain.de/ppc/mda3/disassembly/
the hardware things aside, there are also many possible software reasons for the device to wake up on:
- update of titanium weather
- automatic email checking
- cell broadcast
- if bluetooth is on
- if beam is on
- automatic update of any software...
plus of course the usual:
- incoming call
- incoming text message
- incoming mms
- upcoming calendar event...
so please check the possible software wake ups first to make sure this is really a hardware issue, because that would be a shame, that could be tricky to solve.
or let me put it this way, if it is really the moving that wakes it up, you have the first BA with accelerometer
EDIT: last but not least, it could only be a bug, maybe a hard reset or change of the rom could also be a way to go, since spontaneous waking up is a known bug for BAs
Chef_Tony
If there was only a way to hack the hardware and make this work at least on Edge. I can live with everything else, but its a shame paying for a full unlimited Internet service and only getting G connection Sighhhhhhh
Ok, I had to let that frustration out !!!!!!

Wow! Tony! I really appreciate your complete answer. I mean it.
Yes, as you correctly assumed, I meant wake-up. It just wakes up and continues the routine WinMo operation; no soft-reset occurs.
It's less than a year that I've replaced the battery with a new one. I remember all the funny things used to happen when the old battery was dying. But non of them were similar to this one.
It can't be the Camera. Well, I'm able to use it all the time, and the "camera_detect" has been always loaded in the processes whenever I've checked it. About the looseness thing, ummm, I'm not sure. I tried to knock on it to see if it's more sensitive than other parts. I think the upper part of the device is more likely to wake it up by an easy hit (like knocking). but it's the whole upper part, not only the camera section nor the camera button.
Unfortunately, the software possibility, is unlikely to be the problem:
I've used many ROMs on my lovely BA which 3-4 times of them taken place since the wake-up problem.
The software and the usual reasons you counted, do wake it up. but shakes, too.
Finally, to be honest, I'm agree with you! This is the first Blue Angel with accelerometer. yeaaah! I did it!
I bet my friends that I can wake my BA up, without touching any buttons or screen! It's fun this way, but I comes to be annoying when I put it in my pocket or just put it on a table! and it wakes up... consider the forced battery consumption, unwanted screen taps if I don't lock the screen. God bless A_C! and... .
I know it's a hardware issue (((((
@raizaM: My Thought.... Have you ever taken it apart? One of my BA's had 3 loose bolts inside. All 3 were from what I think is the Radio/Antenna part at top. However, in my case, I had a rattle going inside. Thats why I put it apart. You might have something loose inside, causing a connection to arc when you knock on your phone. If you do deside to open it, there is a tutorial on the wiki on how to.

Hey mark!
I had that same issue a while back, but with only one screw (also from the same area as yours).
@raizaM
Just to knock off Chef_Tony's theory out of the table completely, try to erase camera_detect.lnk from \Windows\startup and SR your device. If Chef was right, then your issue might be gone. However, I would follow markanthony's advice and take it apart in case Chef's idea doesn't work.
Oh man, your not my hero anymore LoL.. and here I thought I would be the only one with a mechanic inside my phone.

Frankly, I'm a lil bit afraid to take my lovely BA apart... :-s... What if... :-(
But, I guess sooner or later I need to do so. so what the heck... lets do it.

raizaM: You're not going to go that far deep. Only remove the cover. If you look at picture #4 on that link, the top green area has about 6 bolts all around it. Those were the ones that were loose on mine. 2 of them were rattling inside the phone. I still can't believe they didn't cause a short circuit. You don't need to go down into the camshell area. Do you use the sliding keyboard? If so, you could have a bad flex cable. But, don't worry about tha for now. Just remove back cover and carefull inspect for loose bolts. Don't over tighten them.
all the master please help, my BA strange,,,,, the screen suddenly go dead after actived wifi or playing game, its suddenly dead, and i must push power button to turn it on again through proses like softreset, that in battery power. but if i conect in charger power mode, i turn wifi,playing game, its normal, the BA still on and working normal,

It seems that you have the backlight settings set to dim/turn off too fast. Go to \Settings\System\Backlight and modify the settings in there (particularly the ones labeled "On Battery Power"). Then, soft reset the device (stylus on the bottom).
Hope this helps.

not the setting, it got black scren, its dead screen after running wifi or application, suddenly goes dead, black screen,.
Have you tried with another battery? It sounds to me like your battery is about to die. It won't hold the heavy battery consumption of Wi-Fi and heavy CPU usage while on Games. Try with another battery. Also make sure you followed Egzthunders suggestion to change your Power Settings. If you still need help, post back and include more info about your device, such as, what version of Windows are you running and how old/new is your battery.
