Hadware Buttons Not Responsive

[dkstinger]

Hi all

I bought a JasJam about an year ago, and it has been working fine.

About 5 weeks ago, I flashed it with HardSPL 7, Radio 1.50 and Schap's 3.60a.

It worked fine till yesterday when suddenly following buttons stopped working: IE, Messaging, Left & right soft keys, start, ok, green & red buttons. Rest of the buttons, keyboard etc are fine. There was no impact, no "sudden movements". The buttons just stopped working! I mean, one minute they were fine and the next minute, they were screwed.

I have done following to fix this (in order)
1. Soft reset
2. Hard reset (which shows that there is no problem with the hardware)
3. Flashing with Schap's ROM again
4. Flashing with 3des ROM
5. Flashing with Sleuth's ROM
6. Flashing with Cingular (WM5)

And still, no use! Buttons still don't work.

Any help would be highly appreciated.

Does the silence says: You have to live with it.

??? :(

More Updates :s

Now I am not able to delete anything I type. :s Not even while using the onscreen keyboard! I can see that when i tap on the backspace button, it highlights, but the text doesn't get deleted! I have tried this in almost any place which allows you to enter text. :s

I think I will go back to my original shipped ROM and bootloader. :S

Strange stuff happening! Downgrading to olipro 1.10 has solved the backspace problem. How can a bootloader affect a function like that? :s

[dkstinger]

Back to shipped bootloader and ROM (not the radio) Still the buttons are not functional.

I also opened up the phone and cleaned the buttons, made sure all connections are properly in place. Put everything back together, and no, the buttons don't work.

What do I do? :(

[dkstinger]

I have tried a thousand other bootloaders, radios and ROMs... But these buttons wouldn't work?

Where are the geniuses like oli? :P

I have the exact same issue.. I have pretty much tried all SPL/Radio/ROM/App combinations, including the 1.01 IPL, original SPL, and WM5 that ships on the Tytn from HTC... And, just like you, the keys sometimes work, and then suddenly they stop. Restart or hard-reset seldom brings them back. I know it's not hardware issue because holding down the "-" and "-" keys while resetting always works. I also observe the LEDs on the front panel go all whacky. Sometimes the power LED, which normally blinks on battey power turns on and stays that way; sometimes it doesn't come on at all.

My guy feeling is that this is not ROM related, and somewhere along the line while I was enjoying the "flash-o-palooza", something got corrupted in the flash memory.

I am now looking for a method to do a "harder-reset" that will clean out the whole thing, reflash the bootloader and build it from scratch.

I think the buttons are not properly passing interrept requests to the OS, which as you correctly mentioned is a flash memory / bios problem. (I don't know a lot about hermes architecture)

HTC provides a diagnostic sd card in which you can check if the buttons work fine. I will try to get my hands on one of those.

Did you try going back to Wm5?

[aarman]

Did you try going back to Wm5?

Yep.. Many times.

[whistler4ever]

any luck with this? can u get to bootloader mode with the keys?

[rscorreia]

not believing that it would be hardware problem, I disassembled already some times my TyTn and I did not have sucess. If someone have sucess, post here please

[whistler4ever]

the only obvious thing is that the keybddr.dll driver is not be loaded properly. how do u normally load the rom's? do u let the software boot the phone, or do you put it in bootloader mode first?

[rscorreia]

as I use a Windows Vista, the ROM upgrader have to be done in the Bootloader Mode
But, Sometimes the buttons works, and in next minute, they die again

its a misterious

I am also experiecing this problem. Occasionally the hardware buttons will work, then if I open the slider they stop working. I have also tried updating firmware etc.. but it hasn't helped. The buttons will work if i press the left and right keys while pressing the reset key to do a hard reset. They work every time doing this, so it seems like a software problem. But I don't understand how a s/w problem like this can remain there even after firmware update and hard resets.

I have opened the phone up several times, because I have another problem, or two. As much as I love the phone it has been totally unreliable. It shipped with the LCD not working, I diagnosed that as a faulty ribbon cable, which I replaced, that made the LCD work. But then the earpiece speaker and the front camera didn't work. Now this problem... this is starting to drive me crazy.......

Hi, I have the same problem, I think. Sometimes when I play games, browse the phone or slide down the keybord the buttons below the screen just stop working. I have also tried to flash different roms, but to no good. There is a temp fix thou but it work slow sometimes, if I scroll with the wheel for a bit(the scroll time varies) the button seem to work, but only for a little while.
Does anyone have any news on this issue, cause i can't use any program that need these buttons.

I also have this problem, I guess I'll have to send it in to get it fixed :|

I have managed to resolve the problem. It started compounding which made me think that it had to be a hardware problem. The first symptoms were that the front bottom hardware keys stopped working. Then the LCD would not align properly after sliding the keyboard, so I would have a white bar at the top and/or left of the screen.

Next the top hardware buttons stopped working, and then finally all I had was a white screen with nothing on it.

I replaced the flex cable that connects the front of the phone to the main board and it has solved all of my problems. I had already replaced this cable when I first got the phone because the one that came was with it was faulty. Now after just a few months of use the replacement one wore out as well. It seems to be the weak link in the build of these phones.

I don’t think you got the same problem as us, if you check almost all the other button problem threads they are about the white screen but since we in this thread have not gotten any white screens or some of the other symptoms I'm quite sure it’s not the same. Also some with our problem have tried to change the flex cable but it has not fixed the problem.

*edit - I did not put the angry smiley on this post.
