touch screen and micro usb don't work properly - One (M7) Q&A, Help & Troubleshooting

hi ,
i have a htc one m7 that is not recognized by pc when it is in bootloader mode, however the phone doesn't charge properly when i plug it in the current because the cable moves when it is plugged.
if i use a micro usb with not long exit, it charges well, if i use a cable with big exit, it moves easily and it often doesn't charge.
the second problem is:
the highest part of the screen doesn't recognize the touch, to use that part i have to press strongly and using the entire finger or a big part of it (if i use the extremity of the finger, it doesn't work ), AND the highest point of the screen ( status bar) doesn't work NEVER.
How to fix micro usb?
How to fix screen problem (i think that is a software problem)
i have not original charging cable
i have just tried to do make electro-shocks to the screen but it doesn't work

If your usb port is damaged you can replaced it. Removing the cover of the phone is a little tricky but once done, the usb board is easily replaced.
You can test your touchscreen by lauching the diagnostic menu by dialing *#*#3424#*#* form there you can access the line drawing test. Test your screen and if some inputs are not registered then your digitizer is probably faulty and will need to be replaced.

[Q] Repairing/assembling G1 -> broken volume rocker and touch panel

Well, I fixed my old broken G1 with new screen, touchscreen panel, case and keyboard.
Now I have 2 issue:
1) Sometimes my touchscreen goes grazy!! If I use the touch test application I see that sometimes when I touch the screen in an area there is another virtual touch in another zone of the screen. I read that it can depend from the current source when I charge the phone.. but I'm going crazy!! I opened my phone 10 times (I thought there was a problem in the cable that link TouchPanel to LCDPanel, because when I lock the cable with the clip it tends anyway to go out from the connector, now I put some scotch tape to fix but the problem is here.. so I think is another problem).
2) My volume rocker doesn't work!!
I bought 2 new keyboard to fix this problem, but no one of that fixed the problem. I thought the first new keyboard had volume keys broken, so I bought another one, but the problem persists!!
Now the Touch problem rarely happens, but the volume rocker is completely unusable..
Someone have experience about G1 assembling/repairing ?
Thanks and sorry for bad english
if you have put in multiple keypads have the same issue i would assume that it is the connection going to the motherboard. just a guess there but its either that or you have had a bunch of faulty keyboards.
only other thing would be a software problem
does the keypad work in recovery (let you go up down throughout the list) ?
as for the touch screen, probably need a new digitizer or flex cable, both are cheap and it sounds like you have the knowhow to replace them.
Ok, but digitizer is new!! screen also is new, and I have bought a total of 4 flex cable because I see that they are fragile (I broke the first I bought).
I tried to change flex cable but the problem remain the same.
The only thing that can be damaged is the LCD cable that links to the flex cable: it has a small cut where the cable have a curve, but the cut don't reaches the contacts (the cable is transparent). I also use some glue and scotch tape to mantein lock the cable.
The digitizer cable is connected to the LCD cable, and then they go to the flex cable that connect them to the motherboard.
The strange thing is that seems a software issue, because if I turn off and than turn on the screen, the problem is fixed for some seconds, minutes and sometimes hours...
Another strange thing is the possibility to control the screen with some metal objects from the moment that the virtual touch problem appear (I can control the screen also without touch it, with hand and piece of metal)
video:
have you tried a factory reset if you think it may be a software issue? if that dosent work you can try install a whole new rom.
really it sounds like it isnt the hardware since you appear to know what youre doing. i have a had a few phones that had screen (digitizer) issues and a new rom flashed cured it just fine
since you dont mind putting a few dollars into it, and your familiar with the inside, you can always try to pick up a cheap motherboard or spare phone from ebay or what have you, then swap the motherboard and you could then hopefully find out if it is the hardware or software

Huh sounds like you got a cheap digitizer than. Most good digitizers use heat to touch. If it's literally touch, then sounds like its a fake/meh digitizer. i hate the digitizers that aren't heat, but press. I see them all the time in those first samsuck touchscreen phones. And they usually die in a bit. I had a Samsung behold with a screwed up digitizer

Yes I flashed 3 or 4 roms after a wipe (I tried also super-wipe.zip), but the problem is here..
The digitizer works well some times, but sometimes get crazy (you can see in the video).
I don't that my new digitizer is fake, but I really don't know!
BTW I'm trying to repair my phone for fun (now I have desire z) and because I am fascinated by my old G1.
PS:
I see another strange issue--
If I touch the screen when the phone is on a table the screen digitizer is not very sensitive and can't take input from fingertips.
If I touch the screen when the phone is in my other hand, the screen digitizer is a lot more sensitive and it take input from fingertips.
My impression is that there is an electric field or something similar that disturbs the digitizer, and when I take the phone in my hand I discharge that field to ground. Also when I turn off the screen, seems that the electric field discharge so when I turn on the screen is ok, but after some seconds the field returns to disturbs the screen.
I really don't know, but is the impression that I have.. something that is not shielded.
Now I'll try to use my phone in airplain mode.
Thanks guys, I'm happy to see that this forum is still very active

Touch Screen broken and micro-usb port broken. How to unlock?

Hi everyone,
I recently drop two times my Sony Z3 Compact on the floor (with a cover, but apparently it was not enough). It fall two times exactly on the same upper-left corner (micro-usb port location).
On first drop, I broke micro-usb port, sd-card port, front-camera (black screen when active), and screen was cracked, but still working.
Then on second drop, I broke back-camera (black screen when active), and the screen is no longer tactile. The smartphone is still functionning, though (I'm receiving notifications, and physical buttons are still working: volumes, camera button, power; and also magnetic port is still working.
It is near to the dead, but I have an important issue. I still need to recover my personal pics which is stored on internal memory. It is very important pics and I'm seeking on all possibilities to recover them, before sending the phone to Sony support (and I believe they cannot recover my pics themselves).
I bought a magnetic adaptater but it seems that it is used for charging only. I tried to plug a microusb OTG with intend to plug a keyboard or a mouse, but without success (since I have the magnetic port working only and microusb port is broken).
Phone is locked with a numeric password, is protected by corporate enforcement rules (if I lose it, they can trigger a factory reset remotely).
Any ideas to find a simple way to fill PIN in it (e.g. with external keyboard, HDMI CEC remote, ?? but I have no idea of what could works with magnetic port) ?
Or a complex way to read internal memory ?

Red LED flashing: bootloader bricked, hardware fault, or a write-off

Hi all,
Last weekend I tried to fix the GPS on my Xperia Z (C6603) - it couldn't lock any satellite and according to all tests it was a hardware problem. When I opened the back cover I saw that the GPS antenna wasn't securely attached anymore (thanks to the third party who replaced my screen last summer I guess). While I was at it, I also wanted to check the speaker since the volume is generally quite low. Doing so I had some difficulty getting the battery out but it didn't look like anything was damaged by it.
I fixed the GPS antenna and reassembled the phone, but now it won't boot anymore...
When I try to boot it the LED blinks red three times and then stops. Nothing more. It only seldomly responds to a cold reset (vol up + power for 10 sec.) but mostly not. When I connect it to the wall socket or laptop the LED burns red continuously.
When I opened the phone I still had about 70% battery left so that should be fine. Nevertheless I've had it on a charger overnight (LED continuously red) and tried the next morning without success.
What I have found is that the red LED indicates either a broken bootloader or a hardware fault. Since it occurred after I opened the phone I would assume the latter.
I have managed to do a repair through the PC Companion software but without result. I can still get the phone in fastboot (LED turns blue) connected to my laptop to flash. The screen doesn't turn on, though I'm not sure if it should? I'm also not sure if being able to connect in fastboot excludes hardware failure?
I haven't tried to root/flash because I first want to ask for some advice on a more systematic approach to fixing it. Also, tonight I will pick up a friend's Xperia Z with a broken screen for spare parts (same model, he got it one month later). So except for the screen I have working replacement parts. Besides the screen replacement (with original Sony parts) the phone was still in original state both in hard- and software.
I would really like to fix the phone since I liked it and I'm stuck to a SIM-only plan until December still. Third-party repair is out of the question because of costs; then I'd rather spend it on a new XZ5.
Any ideas on how I should approach this?
After some trial and error, I have managed to flash a stock ROM (.253) on it. No luck with that unfortunately. When I try to turn it on, there is a small vibration after a few seconds and that's it. Again the phone responds to a cold reset, but when I try to boot it after the LED blinks red three times again. That's all it does.
I would say the only thing to still try now is swapping the motherboard with the other phone, not? Or are there any other suggestions?
Well, I would assume that it is a hardware problem, especially taking in to the account that you touched components inside.
Even if we all know how phone work, and where are all components are, its not recommended to touch anything inside if you dont have steady hand and environment to make any repair(clean place, no humidity, clean hands).
One bad plugged connector can brick your phone. One time I even had problem on other phone with really small rust on one pin that I touched with finger(sweat from it+time+really crappy weather where I had to use it), so it show how actually fragile phones are.
But few questions, when you managed to flash rom, you get all that android logo when you are in flashmode, and it show everything(loading bar etc) on screen?
Im asking because first symptom of bad battery connection is deformed or totally dead screen.
When you fixed gps antenna(that black plastic on top near camera) you used any tool that could damage board? its near microUSB so its easy to mess those small pins and make short circuit.
The same with battery, you could try to squeeze/move it a bit to see if there is any changes in phone boot behavior(not to gentle way to check it but sometimes it show if there is a problem)
Before changing motherboard I would replace battery from your other phone(charged before that) and check all pins on connector and board near it if there is any problem.
But as I said it should be made really delicate and in appropriate conditions.
Sadly I cant really help with it beside that, and I hope your phone gonna stand up after that somehow :/
Thanks for the reply Akinaro. Indeed the conditions are not ideal. At least I have one of those repair tool kits with the small screwdrivers, plastic pick and plastic levers for the connectors. I'll also set a reminder to take some latex/nitril gloves from the lab for next time

No, the screen is totally dead. No sign of life whatsoever.

Possibly. I have used both the screwdriver and the plastic tools, but fiddling everything back in was tricky. The battery was disconnected though so it shouldn't have short-circuited. I will try with moving around the battery. But the more I think of it, the more I start thinking that I screwed up the motherboard by touching something there.

I have tried the other battery last night as well. I didn't charge it first though, I left it in my phone to charge overnight and tried to boot it this morning, without result.
So I've attempted to swap the motherboards. Good and bad news...
The good news is that the spare phone works with every combination of motherboard and battery, so neither of those is the culprit. The bad news: none of the combinations work on my own phone, even with swapping all the other hardware components (camera's, gps, antenna etc.).
On the other hand, by now the LED doesn't turn red anymore. The phone just stays completely off. I didn't have time to try and charge it for some time though, so I'm not sure if it's a good or a bad sign.
I fear that the main multiconnector running under the battery might be damaged when I took out the battery and antenna module the first time. That is the only component that I cannot swap for it is so integrated - it would mean swapping the screen to the spare-parts-phone and using that one.
Any ideas still before I should consider it a write-off completely?

Screen cracked - only upper half reacts to touch. Help!

Hello all,
so my brother threw down his phone. Now it has big crack on the back and a light one on the display.
Despite this display looks ok, but only the upper half reacts to touch ...
So the idea is now to do some backups and then sent it in for repair.
The phone is stuck at the lock screen and cannot be unlocked because the number are in the lower half of the screen.
My first idea is to enable the "Glove modus" (Settings -> Display -> Enable Gloves) and maybe the display will still react to pressure touch... (?)
However how can I enable this modus, is it possible via adb and how?
Any help appreciated, cheers
PS:
The phone is rooted, btw.
Use mouse

What do you mean, exactly?
Maybe he meant to plug a mouse using an OTG cable. I haven't tried myself so i can't vouch for the method
He's right. Buy any cheap USB OTG adapter and plug any USB mouse (even wireless) to Your phone. Tested and working.
Thanks, USB OTG adapter did the trick.

Recovering water damaged z3 compact

Hi All
The GF's z3c recently took a bath in a sink full of washing up liquid, and as it was suffering from the common screen lift issue we suspect that was where water got in.
It was sent off to imend and they cleaned up the corrosion and dried it out, however they found (via replacing the screen) that the water had damaged the display chip on the motherboard and they couldn't risk replacing it.
I've purchased a MHL to hdmi adaptor off ebay (here) and can get the phone screen to display on the TV however the touch screen is erratic and unresponsive. As I cant unlock it I cant mount it as a drive or get at it via ADB (fastboot works but I cant do much with that & it is rooted on the stock 6.x rom).
My next thought was to connect up a USB mouse as I cant pair a bluetooth one and use that but in reading up on it, it would appear that the usb port can be used for MHL or USB OTG not both simultaneously. Has anyone successfully connected a usb device and MHL display on this phone & if so how? My thought is a micro usb hub, mhl adaptor in one side, mouse in the other. Something like this this
Failing that is there any way to get into ADB or pull a backup with only fastboot access?
Thanks
