Hi,
I have a G1 Tim Italy debran T-Mobile (RC7).
After making the rom change , my keyboard does not work, the keys A, Q, write no sense words. For example if I press the A writes amncs, x , or if I press the shift rule the volume.
Could you help me to resolve the problem?
Besides I not have the root permission...for this problem I can't write on Telnet to obtain a root permission.
Thanks
Serena
Please help me
Have you tried just re-flashing the ROM and seeing if that resolves your problems?
Ok, but my pc dont'see the phone in fastmode..., and when I try to install by sd, give me an error message...signature etc...
Found it. Since I found this as the first result on Google for those same characters and know many others have problems without an answer in sight... I took my phone apart and started swapping out boards.
The keyboard actually spans across two separate boards, on the front button panel and the board where the SIM card slides into. The menu circuit board was the culprit. I guess if this board misfires, the front keyboard gets it too.
Interesting the keys worked perfect from a boot terminal. I guess the Linux kernel speeds up the keyscan routine and the higher scan rate picked up the short circuit. I spent earlier in the day doing factory restores, flashing new roms, etc...
I had slight corrosion on my circuit boards from sodium hydroxide vapors. Cleaning doesn't work well in my experience. The only thing that I know completely removes the conductive salts would be melting fresh solder flux on the connections. And they are pretty darn tiny!
Having a similar problem with my G1. del types JHGL and fiddles with ringer volume, enter types amncs,x, spacebar types / ~Z{ , p types pq8yt19d, back types U542i3. searching on google many people have encountered this problem with the same exact gibberish. How can so many people get the same exact gibberish from corrosion? seems unlikely..

I have been running a older version of Dutty's Kaiser ROM for some time with great results, however, I have noticed that my hardware keyboard is slower than it should be. I can press a button and either get no response or two characters typed. Anyone else experience this and know what causes it?
thanks ahead of time,

Use Disable T9 cab
I also had more performance with different radios and spls
There is a recen thread on this
do you know where the recent thread is? or where the disable T9 cab is located? i did a forum search but turned up too many hits and after reading the first page of hits i gave up.
The problem has escalated!
you know I tried that disable T9/XT9 cabs and tricks, but they didn't help. I investigated further as to why my hardware keyboard doesn't respond correctly. I think that I have found that is is strictly a hardware related issue. Only a few of the buttons on my device have this problem, and their not really slow, they just don't type each every time I press them. I also found that the harder I pressed those problem buttons, the more likely it was to actually type them. I might end up trying another ROM and hard resetting the device but if not, I may try taking the device apart and cleaning the keyboard, I suppose I have just typed it to death! If all else fails unless anyone else has suggestions, time for a new phone. Anyone else have this problem with the Kaiser, and another thing. Have a kaiser?, look at the front of it and inspect the shiny button cluster. Does your button cluster move about the opening sort of loosely jiggling around? hmmm........ mine does!

this is a known issue with alot of ROMs that are made from the AT&T OEM rom.

I second both observations.
On my keyboard, it's the R and H buttons that are unresponsive. As to the shiny button cluster, mine moves too. But not as much as my friend's TYTN II does.

You may want to check your key repeat speed and delays in settings->buttons. I had mine set to lowest delay and highest speed. I tried to double the delay, and reduce the speed to less than half. My keys seems to work a little better now (but i've just been testing for a few minutes).
jiggly buttons
my hardware buttons jiggle around a lot. they still work fine, but yes I believe they are just jiggly by poor deisgn.
I'm wondering if anyone else has experienced this problem (searches lead to fixes with keyboard lag, which help a lot, but my issue is different).
My keyboard is incredibly unresponsive; certain key (i.e. P and V) require incredibly hard repeated presses to register. My keyboard has been going down hill since I got it, but now its a downright pain to use (approaching 2 years of ownership). I'm wondering if this is simply a flaw with the device that most people deal with, or if I have a uniquely bad unit? It doesn't appear to be ROM dependent as this is a consistent problem with all.
Is there a buildup of dust/other stuff under the keys? Usually the most common cause of individual keys getting hard to press. Could also be the membrane inside is wearing. Either way, you'll need to pop her open to check.
I have the same problem with F and takes me to stomp on it before input, after time the Kaiser keyboard seems to become this way there are threads that say about opening up a text doc and circling around the key but never helped me, there must be a way to sort it via a new keyboard "or cleaning but pretty sure the keyboard is glued" but i just got used to it as the age of device.
Sorry i couldn't provide a fix but wanted to let you know your not alone
Thanks for your responses...I figured it was probably just dust or wear n tear, which makes sense as it gets worse as it gets older. I've already opened it up once to replace the screen and it was tricky putting it back together (the left hinge isn't perfect ) but maybe once I get another device I will give it a try.
I have my X1 since over a year now, and i don't use the hardware keyboard a lot, but now after nearly a year and after trying many ROMS i choose TouchX 1.9.1.
the hardware keyboard is fine, except for the Space, M and N buttons, very often they skip and i have the press them really hard to get those letters, is it a defect or just dust somewhere? any method of cleaning it?
I had the same Problem on mine. And my Space key often produced three spaces at once.
Solution:
You have to clean the keyboard. Or better; undserneath the key-"foil" and the circuit board with the contacts. Although it seemed clean to me, this helped.
There is a very good video how to get there here:
youtube.com/watch?v=AWDurQrRt-Y
For cleaning I've used a desinfectant which is made mostly of alcohol.
If you use the search function - there is a thread on the keyboard cleaning topic with many photos.
I know it's been said before i've googled it and stuff but when the delete key is hit on my keyboard i get a JHGL and a volume lower key and if i hit the back key on my phone i get a U542i3 input. the phone has NEVER been dropped in water and it just started happening randomly.
is there any solutions i can do myself to open it up and fix it? Im not covered under warranty so that's not an option for me.

You can take it apart and clean it.
But first, I would investigate possible SOFTWARE issues. Wipe it clean and load a new system on it.
Yeah, my friend gave me the phone stock when it had the problem then I wiped it flashed it etc and the problem still occured.
Can you confirm if this worked? I have a similar issue:
I have a similar problem but not as severe. Almost all buttons work ok, just the buttons in the middle of the hw keyboard like y, h, b and space sometimes print other stuff, b sometimes writes a few characters and opens up the search, n sometimes writes some characters with an 'enter' in between etc. and these random outputs are usually the same, ie I get the same stuff by pressing b over n over again. They work fine after some pressing, and I've noticed if I press these keys immediately after pressing something else, they work fine. The problems has persisted through rooting, flashing, radio change, bootloader change etc. Anyone know what this problem is? Is it a hardware issue should I get it checked? The hardware guys here charge so much I have to be sure before I take this to them. Any way I can correct it myself? Any help would be appreciated.

Please let me know.
My torx tools aren't small enough so I haven't bought a pack yet to actually try it yet. Im really interested in fixing this G1 so im not sure yet what to do.
Hi ryohazuki!

I'm pretty sure it's a hardware problem.
On HTC Dream there are several GPIO's involved with scanning the keypad, hardware keys and trackball sensors.
These GPIO's of the SoC (MSM7201A) inside are connected to 4-line ESD circuits to protect the chip, prevent voltage peaks and stuff.
Please have a look at this post or read the whole thread.
I found out that these circuits might be harmed by some electrical effects. As a result some of the GPIO's are shorted and affect the behaviour of your device in a strange way.
It's not sure what exactely causes this short circuit... maybe some peak voltage while using the wall charger or some strange inductive effect.
Maybe these protection circuits are little bit weak concerning electrical specs.
Whatever, as you might see at the date of my posts in that thread, i fighted several weeks to solve this issue and i'm pretty sure it's the same effect that causes your device to go mad.

I have this exact issue. I can rework/solder very small parts and would be willing to try your fix but I really don't think it can be a hardware issue, one because everyone gets the same gibberish and two because all keys function normally in recovery console. What am i missing?
I've been running hyper dragon III on my tilt for the past few years. A couple of days ago my tilt started acting flakey, pulling up sms, email, contact lists, and dialing random numbers ,44924444466634444.......repeating like a stuck key. I reset but to not avail. I took out the battery and reset again, no luck. I figured it was time to replace my venerable hyper dragon with a shiny new Rom. I chose a clean wm6.5 Rom, ahmedfikry wm6.5 23569 Tilt 3D UC light Rom V2 . It seemed to work... at first. I was excited with the speed, the response, of this new interface and smugly back patting myself ... when the buggy behavior returned; hmm, I thought, a bad flash?, so I went back to the wiki, reformatted SD card, reset, rebooted... no joy! It can't be viral...can it, or worse some malignant kaiser killer cancer; can it? Insights, ideas, recommendations? Please be kind, I'm very vulnerable right now....
UPS just delivered my brand new seidio extended tilt battery! It came a day early, oh joy! Murphy strikes again... : )
if it is starting programs that are linked DIRECTLY to hardware buttons, i would suspect your kaiser's buttons or the cables from the buttons have gone faulty (hardware problem).
everything you say seems to point to things that are linked with buttons...there is a button for sms/email, all the numbers have buttons (on the keyboard) and even the contact list is sometimes mapped to one of the soft keys on some screens (e.g. the "All Contacts" button on the contacts page of manila).
so perhaps your buttons are the problem...they might be "sticking" or a cable or set of cables might have come loose or they might have cracked.
the only other possibility i can think of is that your screen protector might need changing. even worse, your touch screen may have gone faulty (hardware problem). you can try realigning the screen but i doubt that will help if the issue is sporadic.
finally, you might want to see if something physical triggers the issue. maybe holding it your left hand upside down? maybe slide open the top? or maybe more frequent when the keyboard is hidden? or try to apply pressure near the buttons or near the frame of the screen to see if that makes the issues more frequent?
good luck!
ASCIIker thanks for your insightful reply.
I fear you to be correct. I did not think to correlate the type of programs and their use of hardware buttons. I did however disassemble my sick little baby last night after posting. I went looking for pocket gunk or loose connections. I had replaced the LCD about a year ago and while it work fine after that, a loose screw wasn't impossible. Too my never ending surprise it booted up upon reassembly, but to my disappointment it began to exhibit the same freaky symptoms. I decided to do a Rom flash, but now was unable to get to my tricolor screen! After about 20 attempts, I gave up turned it off and put in my new battery. A long charge later, I turned it on to drain and train the battery expecting it to resume its schizoid activity...but no! I find a lovely 6.5 win-mo screen an a well behaved phone. I'm determined to solve this conundrum. I would like to say it was the principle of the thing, but really I'm driven by my ocd nature reinforced by cheapo habits. ASCIIker, do you think if I disconnect the 'd pad' connector I might be able to confirm your hypo? I sure I can get it to repeat its bad behavior if just spend some time reloading and setting preferences. Once I get it perfect its sure to fritz out! Either way thanks again.
