I bought this G1 with a cracked screen and I decided to replace the screen, however when I removed a certain part in the phone I managed to rip a ribbon cable. I searched for a replacement part and found out that it will cost about $185 to replace it. Now I am about to buy this other G1 for $50 that had water damage that I will be using for parts. But before I buy it, is there a way I can see whats wrong with it using adb? I'm interested in whether the part that I need is in working condition.
the phones condition is:
-the screen does not show anything but a backlight
-leds work
-rebooting using three buttons work
-lcd is probably screwed up because when i hit the power button i see part of the home background and then it fades away.
-no g1 screen logo while rebooting
-normally vibrates once while rebooting
-android os boots up
-"adb kill-server adb devices" doesn't list me any devices when i hook it up to usb. maybe debugging is turned off.
here is a link to the part i am about to remove
http://www.cellphone-repair-shop.co...icrophone-and-sd-card-slot_50H10000-02M-A.htm
the pcb board has the trackball, usb port, simcard slot, sdcard slot, and various other peripherals.

you ARE SO FUNNY!!!
Why? can I laugh too?
I don't see you turning a profit considering u can buy one for $200 on craigslist easy
its funny cuz its like you trying to buy a coumputer without a mother board. this is the main thing in the g1 it would be cheaper to buy the phone brand new
i have two, one of them needs this part and the other one has the part i need. and plus im fixing it for my brother.
G1 #1
-already Bought for $74
-needs pcb board
G1 #2
-$50 as is
-has pcb board
-has water damage
anyhow I managed to get into recovery and did a wipe logged in but once the screen turns off i cant turn it on anymore. would you say it is safe to exchange these parts?
Wrong Forum, goodness
how is it wrong..I'm not asking anybody to take it apart and do it for me. if it was in the wrong place would it be because I'm not developing something for someone to use. is there a section for modding, taking apart the g1 and internals. if i could develop something i would. i guess there's no help in posting useless remarks because that doesn't contribute to nothing. If this so happens to be in the wrong forum well then this is my first mod now isn't it? and since you went of of your way to tell me its the wrong place why don't you be helpful to lead your fellow xda forum member. ok.
accessory forum This seems to strictly be about discussing the SOFTWARE for the Dream. Accessory forum covers mods and replacements (to my knowledge)
$50 for a water damaged G1? WTF? Are you serious?

do you mean by that as expensive or cheap???

I'd say expensive, as you have no idea the extent of the water damage. If the phone was on while dropped into the water, the mainboard is likely dead. Buying it would be a waste.
Also, this forum is for software development. Moving this thread. Thanks!
hey thanks for moving my thread. as i reread my post it seems more of a question than a developmental thread.
further testing
i booted up
ran through all of the radios wifi, 2g, 3g, orientation sensor, made a call and they all seem to work fine. the one problem with this phone is that if i turn off the screen it won't turn back on.i think that maybe the pcb board might be salvageable. would that be worth doing?
What cable was it that you ripped? What was it connecting? And is it possible for you to take pictures?
my digi cam isnt working but this will do. its like a 1/8" rip on the side of the ribbon i was thinking about repairing but i cant because the ribbon is soldered to the board. i figure that i should try swapping it out, what could possibly go wrong? im assuming that the lcd has lost the ability to regain power after turning off from the water. and maybe...possibly the main pcb has dried up and not been damaged considering most things work fine. thanks for sticking around.
I'm not liking your chances of getting this working, but fwiw here's the service manual:
http://mikechannon.net/PDF Manuals/HTC Dream SM (A04).pdf
Thanks I already have that manual printed out. Took it all apart like4 or 5 times. its pretty easy to do. I'll be starting operation on it tonight.
Hi there, I know there are other threads on this, but I've got two questions;
I might be able to claim a repair on insurance - the policy doesn't state anything about rooting voiding it, but I'd want to play it safe and flash back the original RUU - now, the digitizer works on my phone, but the LCD is totally shot, can't read anything.
It's been a while since I flashed the RUU, so is there any point where you have to press a button or something on your phone to advance? is it possible to use ddms while flashing the RUU to see what you're doing?
Also, if I can't claim this on insurance, how hard is it to replace the screen yourself? I've seen a "genuine" (hmm.) LCD/tools set on ebay for about the same amount as my insurance excess, so this seems like it could work (if it's easy enough!).
Thanks!!

I've not done it personally but I have seen the guys in the phone shops doing it.
It's not that hard, but you have to know what and where to remove. Just go slow first.
pardon this but what is ddms?
Hi,
I have flashed RUU for my Tattoo at least twice. And as far as i remember there is no point you have to do anything on your phone. It will reboot (into fastboot i think). You will se progress on computer screen.
By the way, how can the LCD be broken and the digitizer not? Is the lcd shattered?
This is against laws of physics!
Oh, maybe I got the letters wrong but ddms is part of the android sdk, so you can take screenshots on your computer - also handy if you've broken your screen and need to know where to press.
As for defying the laws of physics, I guess the Tattoo is more special than we thought! the lcd is showing up loads of black/white cracked patterns (but a small it at the bottom works, so I can just about make out my dock. )
Thanks, insurance guys seem to be a bit more helpful now, so hoepfully won't have to resort to doing it myself.
Just in case anyone else has this problem, found this nice photo-guide to unscrewing everything: http://translate.google.com/transla...acenter.ru/razborka/htc_tattoo/&prev=_t&twu=1
haven't got round to it yet, but should do after exams.
Thanks useful info.
I have opened and dismentled everything my tattoo 3-4 times refering the guidlines. It is really helpful.
I was trying to resolve a touch screen problem. My phone acted like something is always touching at a point of the screen, so, I couldnot able to select a thing correctly and it is worst while typing using screen keyboard. So, I disassembled my tattoo and clean everything inside and assembled again. It seems working correctly for few hours then the problem reoccurred. And I disassembled again and again.
Atlast, I found out the problem was just on the screen protector, I have removed it and resolved the problem. Funny problem but it is worth all those efforts.
Bad Digitiser
Recently the Digitiser of my phone went bad. I tried flashing back the Stock RUU but did not succeed since it was not able to detect my phone. Then I just flashed back the backup of the stock ROM and took it to the Service Center. To my surprise the person didn't even check whether the phone was rooted lr not. Since it was out of warranty I still had to pay I still had to pay $45.
Hello,
I have a busted galaxy s (memory card corrupted).. now i can get another one with a broken screen for a cheap price.. my question is, can i just replace the motherboard part where the MC is located, or must i replace the broken screen on the working one.. the screen replacement is a lot harder but i think it wont give me to much trouble.. i am wondering if the motherboard replacement will work without any IMEI or other parts of the phone conflicts.. have never done that before. If someone has, please tell me your experiences.
Both phones waranties are useles and tryed already. They are both unlocked euro phones gt i9000.
Thanks.

The NAND flash is located on the mainboard which is separate from the screen.
You don't need to touch the display with its electronics - there are some display controllers.
Just change the mainboard and that's all
Thank you i thought so too. i had already put my phone apart 3 times, just to see if by some miracle nand would start working again stupid i know, but i was quite desparate..
hi does anybody know where can i find a mainboard for i9000 i googled with no result. i have my screen been replaced. now there are a few grey horizontal lines on it. the strange thing that they dissapere when i plug charger and when the temperature goes up. and sho
wing back when the phone goes colder. in the lab i was told that the problem is in the connector on the main board. and there is nothing to do with it. so can anybody tell me where to find a replacement? thank you.
I have been trying to repair this phone, but the usual faults have not turned out to be the problem. This is the background on the repair efforts:
In my research I found 3 main causes for a dead touch screen.
1) Corruption of system software.
2) Failure of digitizer cable (hinge FPC)
3) Failure of digitizer screen (touch panel)
To check for #1, I flashed the firmware again (after a wipe). I downgraded to Android 1.5 because I wanted to root the phone and install CyanogenMod Android 2.2 Froyo.
This was a big mistake because I learned that when you don't have a working touch screen, you cannot get past the "Touch the Android to Start" screen.
So on to step 2 - replace cable (hinge FPC). I have a G1 parts phone that was lightly used in good condition before it was damaged. There was no damage to the sliding section, so I expected the hinge FPC to be in good condition.
So I installed the hinge assembly with its hinge FPC from the parts phone, but this did not work either.
So next I installed a new touch panel (digitizer screen), but that did not fix the problem either.
I had a chance to borrow a working G1 motherboard, and I was surprised to see that the phone was working with the borrowed motherboard.
So my question is whether my problem motherboard can be recovered with a software solution, or if these symptoms indicate a hardware failure.
I thought that a wipe followed by firmware flash would eliminate all soft system errors, but I am not sure if the wipe and flash really erase absolutely everything, or if there is something else I need to do to get it working again.
Thanks.
more than likly it was the point in the motherboard where the flex cable connects. try using some electronic parts cleaner.
i have ran into this a few times and simply replacing the motherboard has only helped a twice, when i cleaned it up it worked.
That sounds reasonable. I still have some Tweek. I'll give that a try. It worked with the same kinds of problems on computer sockets.
Okay. You are on the right track. When I went back to the phone, I actually got two taps out of the screen, which it hasn't done in a long, long time. (I was running keyboard only for a long time before I could take it down to fix it.) I attribute that to just disturbing the contacts with so many assembly/disassembly efforts.
After I applied Tweek to the joints, it ran well.... for about an hour. Trying again was no luck, so I don't think I'm going to mess with the contacts anymore. By the time you figure how infrequently motherboards come up for sale and the cost, I think I'd do just as well with a trade in on a flat-rate repair.
But at least now we know for the record that there is another cause of dead touch screens.
well i have about 13 motherboards, if your interested let me know
Thanks. What has been your experience with changing motherboards?
The reason I ask is because the service manual wants the phone to be tuned again after a motherboard swap. I see a lot of people changing motherboards, and I can't believe that is much of a problem when you don't see anyone complaining about the phone not working well afterwards.
A spare motherboard might be a good idea for a diagnostic tool. It would have saved me a lot of work changing the touch panel and cables if I would have had a motherboard to try first.
I thought I had a good spare in a damaged phone, but when I took it out the other day to test this phone, I found out it had physical damage too. The SIM holder and RF shielding were dented, but the killer was that the daughterboard cable connector was bent.
I suppose back when the phones were $900 you might try to fix something like that, but it's hard enough to do a connector swap on a computer motherboard. I can't imagine that even the factory has the equipment to properly swap the connector even if you can get the part.
How much do you want for a motherboard? On that famous auction site I've seen them go for around $10 to $30. I could kick myself for not buying the last one I saw at $7 because I thought I had a spare.
Hello guys! Saddly for me my touchscreen stopped working but the thing is that i bought a new screen assembly but i still have the same problem and the same spot doesnt work (on the digitzer, lcd works perfectly). I really dont know what to do i have tried to google my problem but people always solve there problem by replacing the screen and i did the samething and still nothing. I'm running the latest stock rom from at&t now but i have tried to flash viper rom and cleamrom, etc... but i have gotten the same result
i tought that it could be the digitzer connector on the motherboard but it looks new so i cant find the problem...
To be more specific the spot thats shown on the image does work but when i touch it, it shows that iam using 2 fingers when iam only using 1 its really anoying when i use the keyboard. When i touch that spot, the phone starts to select things arround the "dead" spot.
My apologies if i have made some dumb mistakes in the text, i'm from belgium so english isnt my mother laguage.
IF theres no liquid damage.
The phone was working just fine, then mysteriously stopped working in one spot. I would guess replace digitizer (aka glass) But if replacing glass has yielded the same result. Now it gets tricky. Now its either a board level issue or a problem with the Kernel interfacing with its hardware.
Since not a stock device and has been rooted with custom ROM its possible those software mods might have affected it.
My suggestion is do your best to go back to completely stock and hope for the best.

Thanks but iam already on stock i have used RUU to reset the phone, same result. And liqued damage is possible any idea what would help?
Or is it possible that the connector on the board is broken?
As you start to eliminate your possibilities the fixes become more difficult.
If your back on stock everything and still bad then its going back to board level stuff. Meaning the connector on the board or something along those lines.
If thats the case then the fix is near impossible.
Might want to get a good strong magnifying glass out and see what you can find.

ok i will see what i can find, and thanks for your assistance.
Did you ever find out what it was?
My HTC One has a 1/4" section that doesn't respond to touch at all.
Hi
I have the same problem in my HTC ONE E9 PLUS where a longitudinal line along the screen does not respond. Does anybody find a solution for that please?

Most likely a faulty digitizer, replace your lcd assy.
