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?

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 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.

Most likely a faulty digitizer, replace your lcd assy.
Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all

Hey guys
I have a very strange problem with my Huawei P10
About 2 weeks ago, I noticed that two purple horizontal stripes are appearing in a 3-4sec sequence
Normally, I would immediately ask for a repair, but there's a thing which persecutes me: it only happens when I don't touch the screen for longer than 3-4sec
When there's a continuous contact with the screen (e.g when writing a message) nothing happens, everything is fine and dandy, but whenever I leave the screen for itself for 3 or more seconds (e.g when watching a movie), the stripes start to appear every few seconds, and continue until the screen goes dark or until I touch it again, but after touching it it still takes only a few seconds for the stripes to sequentially flicker again
Here's what I've tried so far (no result):
- safe mode
- factory reset
- cache partition wiping
- cord input deep clean
What may be the reason?
Hey.
It's 100% a board or Display issue. send it for repairs. but i believe maybe you've dropped ur phone. Anyways Huawei knows better.

It's quite complicated
I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I can't really answer for sure but i believe if there's a Huawei service center in your city and you try to fix ur broken huawei, your wasting your time. Whatever solution u apply on ur phone its just gonna be temporary since u hide your problem and not solved it.

I still think (or should I say believe ) that there's a solution which doesn't involve another screen replacement
As for your "temporary solution" mention, I guess if I found one, it wouldn't be temporary, since the fault doesn't progress, it's been the same for a month or so when it first occured, which gives me another reason not to replace the screen and keep looking for other possibilities
I don't need a Huawei service center, I can replace the LCD myself (didn't do that the first time though), but it still involves spending money, whereas I've been looking for unpaid solutions the whole time; getting a new LCD is an extremity

You can ask them to diagnose it and tell you about problem noone makes you pay for a lcd. And after reading your message over and over (And since i repair TVs and everything with electronics inside) i think it also can be your touch or display controller ic. Mostly it could be from touch ic since screen works fine while its in touch with something. But someone has to try your lcd or mb on a healthy one to make sure. which you can't do nothing like that. or do you?
@fengels did You bought original lcd, where can I buy it in good price?
I know this problem from older galaxy series like s5. The fix for this most of the time was disable auto brightness or higher the brightness on auto brightness. Don't know if this is the same problem, but it could be a try. Also don't know which cause this strange problem. Hope it can help you

No, it's a different problem, in the galaxy series the whole screen would flicker, whereas in my P10 it's only 2 horizontal stripes appearing in a 4-5 sec sequence whenever I leave the screen untouched for longer than 5sec
Playing around with the brightness doesn't solve that unfortunately, actually no in-device settings do, as I've tried almost every single option which is screen-related, like switching the eye comfort mode on, but still no result
The main reason why I'm still looking for an unpaid solution is that apart from this one error, the phone is like brand new, everything works fine
ok, so if I understad the problem shows up after you replaced the LCD display? So do you really think is more software related than hardware? I personally would send it to diagnose and repair.

The thing is it didn't show up immediately, I had used the phone for some time with no errors before it first occured
Also, since the new LCD was set, I haven't done any physical damage to it, I've never dropped or sunk the phone
Since you guys mostly advise me to send it, I guess that's what I will have to do

While you were replacing screen, did you turn your device off and disconnect the battery? and i think cleaning all cables coming from LCD and related sockets on motherboard can help. Use thinner or alcohol and if you wanna use thinner be careful so it wouldn't touch anything except golden contacts. Thinner is dangerous and affects ur phone color and plastic parts.

I did turn the device off, but I didn't take the battery off, since it's strongly glued to the phone's body, and I didn't want to damage it
Anyway, could not taking the battery off really be the reason?
As for cleaning, I did it by simply blowing out all the potential dirt, I'm inexperienced in thinner and alcohol cleaning

I am not sure butbon some phones it damages screen. I've seen this on laptops. But anyways its done. Open ur phone and use alcohol. put 2 drops of alcohol on each socket and flat cable connectors and brush it with a soft brush. u don't want to bent any golden contact. It's last thing u can do to fix it without paying for hardware related stuff.

Well, will definitely try it then, but what alcohol? Does it need to be something specific?
