[Q] Need to diagnose a X10a 'motherboard' - XPERIA X10 Q&A, Help & Troubleshooting

Hello everyone,
A friend of mine destroyed his X10a, says he dropped it, but looks like it was run over by a truck... At first sight it had the digitizer destroyed with flex cable completely cutoff, broken LCD and the battery sustained some damage.
Then he told me that if I could repair it, I could have it... Naturally I though, 'replace the broken parts, let's say ~$50 and new phone for me! but before running to eBay, I wanted to be sure that it only needed a new 'screen'
The first thing I did, press the power bottom (though that if it gave any signs of life I could just put my SIM card in and call from another phone, if it rang I would smile) and... a red led blinked 3 times, when lucky. As I have never 'played' with a X10, I had no clue what that meant so my quest for knowledge began... and after reading I found it meant low battery, so plugged it to a wall charger and the only thing I got was a blinking red light, same with plugging it to PC with USB cable, which I think it's suppose to mean bad battery. So left it overnight charging... and never got anything but a red light. (no orange light, no green light, not even a steady red one) and if I pressed and hold the power bottom, it would vibrate.
Well, time to open it and see if there's anything else I haven't seen... and after opening it, found that the keypad flex cable is almost cut off and it seems to have some damage in the lower right corner of the 'motherboard' (looking to
where the battery goes) near the antenna connector? (I'm assuming it's an antenna connector, the round thing with a hole, it's a little down from where the LCD connector is, will upload a photo, but at 5:42am I'm surprised I'm still writing...)
1. How can I test the 'motherboard' ensure that it's functional?
2. Does the X10 need the battery to turn on, or can it be turned on with just the wall charger (and no battery). Will it turn any light on?
3. Does any of the damaged parts (no digitizer, LCD or keypad) prevents it from turning it on? (guessing the keypad might). Hopefully someone really brave, thirsty for knowledge and dieing to help will open their X10 and try to turn it on after various combination of disconnected components, let's say without LCD, digitizer or keypad... just to analyze it's behavior and help me...
4. Any idea? or just not my lucky day?
P.S. When I plugged it in to the computer it was as if it wasn't there... PC Companion and SEUS did not recognize it (not even windows 'sees' it)
Thanks in advance!
...Yey! my first post in this forum!

Hi,
almost all of phones I had ever serviced needed plugged batterry.
You may even need the thermistor (middle pin), because phone controls resistance and temperature of original baterry. I am not sure about X10i,but power supply is nessesary I`will take my multimeter and check it out once in home
But before plugging any power source, be careful about static electricity and check if any of flex cables are not short-circuited!
A also may provide complete PCB schematics if it could help you (but they are very very difficult )

A 2-year-old model that looks as if it had been run over by a truck is not worth the hassle, imho.

First test a new battery in a shop
And i think that u say keyboard then it would be x10 mini pro

It depends of sense with you are using your phone - my old 3410 and K310i still looks like new. Unless batterry exploded...
My phones were used very often then

No, he spoke about keypad. But doesn`t depend on model - baterry is dead I thought.
But better is if he use stabilised power station instead.

[Solution] Worst battery scenario and impossible boot

Hi all,
I just want to share the solution I used to solve a big shared problem I had with my X10 Mini. During a call my battery went so down I couldn't even turn it on without any sign of hope. As we know in this cases the phone CAN'T charge itself cause it need a software "help" and without a minimal charge the phone is dead. In my case scenario even with Seus holding back the button couldn't solve it.
I decided to solve it without taking it to the 60km away SE support center and:
- taken apart a usb data phone cable
- divided the red wire and the black one
- considered that the USB port gives 5v at 0.5ma
- taken apart the phone case and the rubber cap on the top of the phone
- take out the battery wires connector from the logic board
- inserted red + wire into red hole of the battery connectore and same with the black ones
- connect it to the usb port of a spare computer (you could sacrifice it if something goes wrong)
- wait for a hour to have a good charge starting point
- disconnect everything, reconnect connector, close case and connect to the normal micro usb cable
- evrything will charge as usual.
NOTE: If someone try at his personal risk, BE CAREFUL cause if something cause wrong you could ruin battery, or logic board or pc motherboard!!!
See attachment.
Bye
Nice hack!
Thanks for sharing.

Good job, but did u try to charge for a few hours without SIM card? Because I already drained completly and solved problem just removing SIM, putting to charge and waiting. After 2 or 3 hours the system start to charge normally.
WTF? This phone has this problem? Did 2.1 fix it? My wife has the habbit of letting her mobiles die.
I hope that she will not need to take out the SIM card every week to charge her phone.
Thanks for the share by the way.
Yeah this phone got this problem and it's quiet usual I see in different forums. But not always it drains so much like me. I did the BIG error to try a couple of times to turn it on. I tried any combinations of tricks with or withous sims differents ones, different buttons, different charger, etc.... No way! I think that SE support centers has got some kind of charger that has got the female connector of the battery to solve this problem.
Ah I now realised you have a mini and not a mini pro, as mini pro's can have their batteries removed.
I hope I will not have to solve this problem , any time soon.
Good to know anyway.

[Q] Touchscreen problems while charging

Hi.
My x10 mini pro has terrible touchscreen issues while being on dc charger.
For example arranging icons is totally impossible and the upper panel keeps on showing up and stuff.
As a result the phone is almost unusable as long as it's on charger. But when charging via pc everything seems to be perfectly ok.
Anyone has the same problem? Or did I just get a defective device/charger?
Also, my battery lasts for only some 4-5 hrs. I've had the phone for 4 days now, so i'm still givin it quite a business, but 4 hours? Seriously..
Well I don't think that is normal , you better take it to where you purchased it and tell them about the whole thing that's not normal.
Thanks, the thing about the touch screen really *is* weird. How about the battery persistence?
Is your phone Android 1.6 or 2.1? I have the same problem before but the problem with my phone not only happens when it is being charged through charger but also while connected to USB port on a PC. I had it replaced with a new one. They said it is a hardware issue but others say it only happens when they upgraded from 1.6 to 2.1 so it is probably a 2.1 bug.
Well, to be honest, I dunno.. I've upgreded to 2.1 right away, so I don't remember if this appeared on 1.6 as well :\ But I don't wanna run on 1.6 anyways, so this doesn't bother me really
I had a similar problem on my mini pro but ONLY when using a charger other than the SE one that came with the phone; fine with PC USB charging or from the SE charger but goes crazy with false touchscreen presses or the TS failing to respond at all on one occasion until I figured out it was the non-SE charger. I think the issue may be that when using a stand-alone USB charger, the SE version supplies much more current than a standard USB port; presumably, when using a port on a PC the driver SW adjusts the charging current to compensate but non-SE chargers may not supply sufficient voltage under the charging draw the mini pro wants.
yeah~ just go for a ORIGINAL charger, don't buy a cheap one, buy a better one! it's the charger problem
My work-around
Hello all,
I'm experiencing the same problem and might have some new insights. I have tried multiple chargers including the Sony Ericsson charger that came with the phone. These are my findings:
- SE charger (wall socket 2 USB) (5V, 850mA) - The problem occurs, however I'm able to navigate
- Cheap Ebay charger (wall socket 2 USB) (5V, 1000mA) - The problem occurs, can't even get passed the lock screen
- Cheap charger (complete charger, no seperate USB cable needed) (5V, 550mA) - No problems
- Charging via USB of laptops and desktops with the USB cable that came with the phone (5V, 500mA) - No problems
Needless to say that with 500mA the charging takes very long.
BUT...here comes the kicker (and my solution):
- HTC ORIGINAL AC EU WALL Charger TC E250 USB ADAPTER (Wall socket 2 USB) (5V, 1000mA) - Charges fast and no problems.
So, in my case it seems as if the problem occurs while charging above 550mA and probably only with cheap chargers, including the SE one. The original HTC charger works like a charm.
I also found out that the touch controller is right next to where the micro USB connection is located. (google "Sony Xperia X10 Mini Pro Teardown and Analysis", I can't post links here...)
Apparently, bad chargers interfere. Hope this helps.
i do use original SE charger and don't even have another but what Neliscornelis posted might be useful THANKS!
I use original SE charger and haven't any problem
I get this problem to.. What i have to do is hold the lock button until the power off screen comes then cancel.. Also I have another problem when in calls.. the screen blacks out every time i try to end the call!! Does aqnyone else have this?
touchscreen problems
hi! i have similar problems!
that problems occur when connecting phone to my pc with original SE cable.
also tried with another original usb->microUsb SE cable, and problem stays...
no matter what charger I use, i always have same problems with touchscreen.
also I tested it with original htc charger and everything is same again, touch screen is registering multiple taps!
so, for now i tested this situations, and problem is always occurring:
-when connecting phone to pc with original SE cable
-when charging via wall outlet (tested with 2 original sony ericsson chargers)
-with original htc charger
only exception, when everything is working fine is when i plug phone in my car (via car lighter->usb adapter)
any solution?
thanks
I can confirm this bug. Original charger 1.6 and 2.1 all the same. The phone seems to be registering random touch events without any physical input.
Also, the proximity sensor doesn't seem to be working while charging. Combined with the false touches, making calls with the phone on charger isn't something i'd recommend.. :\

I am experiencing this one too. I think it's the static from our skin.
I tried putting my finger in front of the screen like less than half inch above the surface (but not touching the screen), and it activates an icon. I can do it all over, so I know its not just a delay of the screen from a previous touch.
The notification bar above also goes like its going crazy or like flickering.
The touchscreen i think is plastic and not glass thats why it's prone to static.(not sure). but whatever that screen is made of, there's some sort of static going on.
Hi i think that the unresponsive screen is due to the fact that its actually oversensitive. i mean the screen is sometimes activated by the sides of the phone and the botton of the screen where the xperia logo is. I am wondering if there is a file that changes the screen sensibility? dont you know how to do it? rooting the phone or something?
Other idea im having is to dissasemble the phone and put something under the black plastic where the xperia logo is to reduce the sensibility of that area. any ideas?
I have record a video watch it to see what i mean with oversensitive. And yes this is a new out of the box xperia x10 mini

Unrelated effects. It isn't static, it is capacitance. These phones have a capacitive touchscreen and your body contributes to the electrostatic field that is part of basic capacitor physics so that it is possible to affect the field to register a touch by merely moving a finger close without actually touching. This is normal. The problem with random touches (when no finger is even near) and the charger problem is not normal.

Dont get me wrong when i ask you this, but what do you think how much your battery like to be charged with that charger? How much you think it will last?
When i charged mine with original SE charger (5V, 850mA) it takes me less than 2hours to fully charge it.
When i charged with PC USB it takes it about 4-6hours.
So, im sticking to charging mine with PC USB..

Really? Mine lasts 2 days with data traffic on, wi-fi, gSynh, gTalk and gMail always on (cause of my work).
Did you followed guides here on forum regarding a battery?
There is a guide of deleting batterystat.bin file in your phone (must be rooted)
batterystat.bin is file that Helps Android read your battery. Its not quite accurate, so, after every reflash/custom you should fully charge your battery and delete that file.
Process that i do after every reflash/restore/messing around.. I fully charge my battery via PC and leave it for ~30 more minutes. I delete mentioned file while my phone is connected via USB to PC, reboot phone and remove USB while it boots, that way, your android will see fully charged battery and pass that info in baterystat.bin, after that, im not connecting my phone until battery is fully depleted.. that way your baterystat.bin will have max and min values for battery. But, its only me, no one needs to follow this..
Also, i read that battery life can improve over time (until batterystat.bin hits the right values)..
Edit: Download Advanced Task Killer from market, it will help you kill unwanted tasks, thus saving your battery life.
Do you think that changing the digitizer will fix the issue?? Its like $20-$30 on ebay. And this phone its extreamely easy to open and change the digitizer in home!!
Or could this be a problem within the phone itself? i mean everything works except for the touchscreen!!

[Q] Got a non-working Xperia X10, based off these issues, what do you think is wrong?

I've always been a huge sucker for good-looking phones, and the Luster White Xperia X10 has a great, unique look that isn't really matched or surpassed by any of the new Xperias, or any new phone at that.
So I got one... going by the eBay listing description, the USB charging wouldn't work because the USB port is messed up (which I prepared for by buying a AC charger)... but that aside it was supposed to work flawlessly.
Thing is, it doesn't.
As soon as I put a freshly charged battery in, I held down power and it vibrated like it was gonna turn on... and never did. Screen stayed black and I ultimately never got it to a functioning state. Been trying all kinds of desperate measures such as trial and error with USB insert angles to see if it was just "touchy"... and even trying to see if I could just get SOME form of response via recovery mode. And nothing worked so far. Sometimes trying to power it on makes it vibrate for a half second before it does nothing, and sometimes trying to power it on will just make it start vibrating endlessly unless I yank out the battery... but not once have I seen this damn thing power on normally.
The seller says he's quite surprised at this because, even when the USB charging officially stopped working, he was able to power it on and make a test call before the battery died (he did dodge my question about how long ago this was, which seemed a bit mysterious). The closest thing I can get to this phone showing "life" is that the LED indicator does blink red when the battery is completely depleted.
At any rate... he's offering me a refund... but I kinda just want to see this work.
What do you guys think? Any more tricks I could try to do to make this respond/test it, or should I just abandon all hope?
I would disassemlethe phone, unsolder the damaged portfirst -it might cause some power shortcut or even in betterlight ofbiewit takes the phone into some strange mode (eg. some resistance between pins can do this).
Or in the best way use the logic analyser connected on data links,but expectyou dont have one

[Q] Evo 3D won't charge, only buttons light up - dead?

Hi there, XDA folks!
Mario here with some phone problems..
I have a CDMA Evo 3D running on the stock ROM.
The phone's charging cable was shorting out ever since I bought it (got it 2nd hand). I had to wiggle it in order to get the phone charging.
I gave it to my girlfriend to use it for taking pictures n whatnot while outside of town. She returned it kinda Rambo-ish; the front of the phone basically fell apart.. the front metal grill surrounding it, at least.
Phone worked fine, except for the cable shorting out even more. My laptop shut down every time that happened, so I'm quite sure that's not what caused the problem I'll be explaining later on in this thread.
So let's get to the point, shall we?
My phone was really low on battery, something within the range of 2-5%. I tried charging it, but the wires shorted out again and the laptop died on me.. again, and again, and again..
I couldn't really bother with fiddling around with it until it starts, so I just unplugged it and left it that way.
The phone sat for a few days, my (main) laptop broke, so I decided to give the good ol' Facebook Messenger a go.. sadly, the phone would not turn on or start charging.
I removed the shrink-like wrap around the wires of the USB cable, cut the bad parts and twisted the color-matching wires in order. Sadly, the phone would still not charge.
I tried with another (self-made) USB cable... no luck whatsoever. Just to clarify; the blue wire on the one the phone comes with is ground, right? If not that could of caused the problem, since I connected the blue wire on the mini-usb to the black one on a standard USB plug.
I tried juicing the phone up a tad bit by running 5V on the battery for 15 minutes or so.. didn't really bother going for more, since it's kinda hard to keep 2 wires pressed against the battery for more than that. The phone powered up, but the display did not. There was the low battery sound, volume keys were functional, vibrating feedback was okay.. hell, the phone even took a screenshot when I pressed power button + volume down!
Sadly, that didn't solve anything.. even turned on, it would not charge. The 15-minute charge is good for a minute of red blinking light and fancy glowing buttons, nothing more.
Is the phone dead, or should I give it a hour charge directly and see how that goes?
Thanks in advance to everyone who replies!
i think it'll be good if you buy a universal battery charger for phone. so you can charge your battery without plugged to the phone

I am looking for more opinions before I spend cash I don't have on chargers that may not work.
If you or someone else is positive about the display not working because of not enough battery juice, then I'll manually charge the battery for an hour, even though it's uncomfortable as hell to hold 2 wires on the pins for that long.
What's bugging me is that it's not charging once it has just enough juice to power up everything, no display either. I'd like to know if it's doing that, because the battery is too dead to actually start charging up via the phone and whether the display just doesn't work or there's not enough juice for it.
Edit; I bought a chinese charger that charges the battery directly (2pins). The display still does not work and the phone will still not charge via the cable. Could it be a bad cable (and a dead display..)? It seems like the phone itself is responsive - I unlock it, press the "search" button and when I type on the keyboard (that I don't see), it vibrates with every pressed key.
Also, I can hear it taking a screenshot and the volume down/up buttons seem to be working fine.

this is exactly what's been going on with my phone as of a few days ago.
checked the time while it was plugged in, unplugged it...screen froze.
hasn't turned back on since.
the buttons on bottom light up, though.
i can take calls, use my unlock pattern (it takes me a few tries now that i can't see anything) and press the search key for google now.
for all intents and purposes...phone's fully functional...except i can't see anything going on.
i brought my phone into a sprint corp store, they changed the top housing for me screen and all for free.
it was really nice.
but, that didn't change anything.
screen still doesn't change anything.
they said the board probably shorted on screen lead.
have you figured anything out?

Nope, I'm still in the same situation.
Does yours charge?
My phone isn't recognized by my laptop at all, so I'm guessing something is indeed fried. I don't have the appropriate screwdrivers to open it up and inspect the board, otherwise I'd open it up and check it out.
If you have Torx T5 & T3 screwdrivers you should give it a go - post some decent-res pics over here and I'll at least visually inspect it.
I genuinely don't feel like spending more money for tools n whatnot for a phone that may be permanently dead.. planning on getting a second-hand S4 anyways. Waiting on a student loan and smashing this phone to pieces as soon as I get the cash for a new one. Can try and help out for yours if you manage to open it, though. Could be something as simple as a dead resistor that shouldn't be too hard to replace.
I tried the hillbilly method and hit my phone a few times against a wooden bench, that didn't seem to fix it. Pretty positive something's fried, but I'm also guessing it isn't a viable component, having in mind the phone functions normally, even though the display & usb port don't work.. hell, my phone woke me up at 3AM today, 'cause the alarm went off, lol!

[Q] Z2 died yesterday (out of the blue) - newbie here, any advice appreciated!

Hello,
I have an unrooted Z2. With around 30% battery left, I put it in the charging dock on my desktop yesterday evening. After 1 or 2 hours, I noticed that the phone is completely dead - no LEDs are blinking, no vibration, nothing. I tried pressing the power button alone, in combination with VolumeDown, VolumeUp, CameraButton, for more than 30 seconds each. I tried pressing down the tiny red button next to the SIM slot for awhile. Nothing. Phone is dead like a brick.
The only result I'm getting is when I plug it into my computer (ubuntu 14.10) - the LED bar on top is showing a constant red color in this case. Doing the button presses outlined above in this situation is also pointless.
I'm installing flashtool for Linux right now, the connection is pretty slow and it will take awhile. I hope to find out more afterwards. I'm a newbie when it comes to flashing sony phones, only found out now about flashtool. Any advice/tip on how to proceed, or if it even makes sense to dig into this, is highly appreciated.
Thanks in advance!
Hello,
are you perfectly sure your dock was connected properly and it hasn't discharged your phone? Maybe there was something wrong with it.
I had similar situation while I was low on battery and I was creating backup in recovery. Then I fell asleep and I have found my phone completely 'dead'. I connected it to the wall charger and nothing. No led, no nothing. I have even connected it to my pc and also nothing happened. Then I connected my Z2 to the wall charger and I left it like that. And after few hours, out of the blue, just turned itself on, just like my old Nokia n95.
I'm sorry it's not quite solution you looked for, but give it a try. Essential is to charge it via wall charger.
Good luck!
Do what @amon87 says OP. Charge it on a wall charger for a minimum of 3-4 hours; If that doesn't work, can you specify whether you were using a legitimate Sony dock or a third party dock? If it was third party, it could possibly have caused a hardware problem with your device via the magnetic charge pins (not extremely likely but not unheard of). Worst case scenario, send it back to Sony in the next few days. The warranty will cover it if you haven't caused water damage or anything like that.
Thanks for your replies! I also hoped for a sudden discharge, so I removed the device from the dock, plugged the USB in directly, and left it overnight - still nothing. Also, I have the original Sony dock, and have never exposed the device to any water.
Found out the model number in the meantime, it's D5303, if it's of any help. Flashtool does not see the device, unfortunately. I just found out that Sony describes an option to restore your device through the official PC companion app - I'll give that a try when I'm home, and will report back tomorrow.
Otherwise I guess my only option is the warranty.
There's also an option to quickly plug in and out charging wire to kick-start the battery. Unfortunatelly i have no further ideas to help you out.
Don't give your hopes up, try again. There's been a thread of a guy whose Z2 turned itself off and it seemed dead, but after a day or two it just turned on.
So, of course it's also not detected by Sony's "Bridge for Mac" app. Plugging it in and out brought also no results.
As the device is still covered by warranty, and I have yet not tampered with it, I've sent it in for repair! My pocket feels so empty now, i wonder how life is going to be without a phone. Apparently they need 5 - 10 working days.
Thanks for your kind support, guys!
Sorry to hear that. Hope it will get fixed!
