Hi everyone,
I recently bought a faulty Samsung Galaxy S3 with a smashed screen to repair it and then use it for myself on eBay. But the fact is that when I received the phone, even after charging, I could have no response from the phone, it means no sound, no vibrations, and no backlight, no LED. But when I connect a charged battery to the phone, it starts heating at the SIM/microSD zone part itself, without me pressing any button until the battery life is finished. Same response when plug the phone to the charger. I don't have any response from the phone while pressing buttons and it is not recognized by the computer. The seller told me that the phone fell and then it could not turn on, indeed. But do you think this situation is caused by a Sudden Death Syndrom on the motherboard? The motherboard heating by itself when battery is charged. At some point I know that the charger, the USB connector port and the battery work, but not more information.
Do you guys think it is worth buying a new screen to repair it in this situation?
Thank you.
Hard to know until you fit the screen .
But in your shoes and from your post i would cut your losses .
No point buying a new screen followed by buying a new motherboard .

Thank you for answering. I think I should borrow a S3 from a friend and then test its screen so that I know if I have to resell the phone or not. But the motherboard heating when connecting charger by itself seems weird to me. Anyway I have to try with a friend's screen.

Hello,
Saturday I went out, my HD2 only had like 5% battery life. I used it till it went black. The day after I wanted to recharge my phone but when I plug the microusb in to the wall charger, no led lights come up. When I press the power nothing happens. Stays black, it's like a dead stone now. I did not flash the phone for the past 2 months, it's running android already a long time now.
This morning when I pull the battery out and put it back in and push the power button then a VERY short vibration comes out of the phone but then nothing anymore the screen and leds stay dark. If I try it a second time nothing happens. So I think the battery is 99.9% empty and I can't charge it anymore through the microUSB. The only thing I can think of what happened is saterday I took a bath and my phone was lying on the edge of the bath, it did not fell in the bath offcourse. But there was alot of humidity in the bathroom because of no ventilation and warm water. The phone was working perfectly after the bath and stayed working untill the battery went to 0% when I was going out. Is my microUSB port water damaged? The stickers inside the phone are still white. (luckily). Anyone has an idea how to fix it or what the problem could be?
Remove the battery.
Connect to the power supply.
After a couple of minutes, plug in the battery (while the phone is still connected to the mains supply).
Ok I tried it.
Took battery out. Connected to usb power cable.
Waited +- 5 minutes. Inserted battery -> nothing happens.
Won't turn on, no led lights.
BUT I noticed a strange thing.
If NOT connected to power cable : Take battery out, reinsert. Power on, -> some milliseconds of vibration.
If connected to power cable : Take battery out, reinsert. Power on, -> nothing, no vibration.
So if it is connected to power cable phone acts completely dead when I reinsert battery and push power button. But if it's not connected then when reinserting the battery and I push the power button then a very short vibration is felt.
Weird ... is there something shortcircuiting the phone when connected to powercable??
Ok,
I found someone on my work who has an HD2 like me. So I tried to put a 70% charged battery in my HD2. Guess what ... same result. A little vibration and it stops .
So now I know it is not the battery. It's the phone itself. I've put it now in a bowl of rice and hope next morning it will be magically revived. Maybe when I took a bath saturday there formed some micro water bubbles inside the phone and it still isn't gone by now? I am out of ideas. If this rice thing doesn't work I'll send it to HTC repair centre. They won't notice my hspl because they can't even turn on the phone with a charged battery. I'll guess they'll swap the mobo .. again. My previous repair was because my HD2 was in a constant Carkit mode (also a hardware issue). Sigh
Can you get into Bootloader Mode (Press and hold the Volume Down button, then tap the Power button)?
Nope, it acts like dead meat, even with a charged battery I could try from my friend his hd2. My battery worked in his phone. So it is my phone who is broken.
Think some hardware is busted ... Maybe some circuit is broken ? I just don't know . Now they must repair it for the second time. The first time I got the "phone is always in carkit modus" issue which is also hardware related. I hope they will not make a problem to give me yet another motherboard and yet another IMEI . That will be my 3rd IMEI on this phone then.
Hope they pick it up tomorrow .
K Update to this post.
I've received my HD2 back from HTC repair with a new motherboard / IMEI.
All is working now again .
I am afraid it can happen again . This is my 3th IMEI / mobo now on this phone after owning it a year and 2 months.
They now also didn't put a new "VOID" sticker on the screw
Also no "water detector" anymore.
It seems like they are saying to me, now if the phone breaks again, you have no warranty anymore. It's not my fault the mobo suddenly dies . I doubt it they just "forgot" to put new void stickers on.
Never take cell phone in the bathroom.. especially if its a touchscreen.. the steam from hot water gets accumulated inside the phone and ruins it. My friend damaged his 2 handsets already.. now he doesnt take it in the bathroom anymore

There are water dector labels inside the phone and if they forgot the VOID label then that is their problem. You have twice returned the phone and by replacing the motherboard they have admitted that the problem is theirs. So they already have a history of faulty phones from you and since it has been repaired by them, then they would need to show a record of placing a viod label back on the phone.

Well I also think that was the cause the phone died later that evening.
I think the phone went dead sometime that night because of the water inside the phone. Luckily the water detection labels where still white .
I never will let it inside the bathroom again .
As for the void sticker problem, I will contact them to ask why they didn't put on new stickers. If they don't respond I saw you can buy such stickers on ebay .
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.

Hello Everybody
My phone was working fine until last night when the battery completely drained while i was playing a game and it turned of. After that i plugged it in and went to sleep. i woke up this morning and tried to turn it on and nothing happened. I took the battery out put it back in and it started charging. i left it there for 20 minutes and when i came back the phone is completely dead. no response. won't charge, wont turn on, wont vibrate. nothing
so if you could help me out with the problem that would be great. thank you.
The battery may have shorted itself. You can purchase a new one for ~$10 on Amazon.

Thanks for your help. I just got done testing my battery in a friends s4. Its not the battery. His battery doesn't turn on my phone and my battery is fine in his phone. Its my phone that has a problem. Any other suggestions you might have will be really helpful. Once again thanks.
Well, if a charged battery isn't making it turn on at all, then the logic board is probably malfunctioning/hard-bricked. The only solution to that is to replace the logic board. Your best option, if you are in warranty, is to contact customer support and have them send you a warranty replacement. If not, the best option is to purchase an S4 with a broken screen and swap out the logic boards (better be comfortable prying open your device).
Thanks for the help.

Hello,
I bought a cracked Galaxy S3 which I used for a few months before I tried to repair it, I have successfully replaced the glass only on a Galaxy S3 before.
Anyway I accidentally pulled the lcd in half, So I bought an LCD off Aliexpress and it arrived earlier today.
I just replaced it then and expected to put the battery in for it to turn on, But it won't....
I've tried plugging it into a USB, And not getting any response on the screen or from the computer. Also tried a wall charger and it's not showing up any picture..
What have I done to it? The battery wouldn't be dead because I didn't have it in while attempting to replace the glass
You can try a usb jig, otherwise a repair centre.

Make sure that the battery is charged then try booting in download mode.
Press and hold volume down, home and power button. If it boots you're lucky. if not, try the the usb jig suggested by boomboomer.
Search on how to unbrick (your device model) and start from there.

How could it have it been bricked from a front glass repair attempt?

Many glass repairs are ending up with a faulty phone .

I see, What causes this? I believe I applied more heat than I have previously. But i've also seen people using a heat gun
Is there any point buying a jig to test it?
All a jig does is access download mode if the three button method does not work .

Heat, heat is death to electronics.
Good news everyone, The phone miraculously turned on.
It was behaving erratically and not booting, Screen flashing on and off but after being charged up a fair bit it seems to be working fine
Thanks all
Hi. I was just browsing on my rooted galaxy s2. Suddenly the whole screen froze. It would not do anything, so i decided to take the battery out. When i put it back in, it turned on and was stuck on the "samsung galaxy s2 i9100" screen. So i decided to take the battery out and try again. This time it wouldnt turn on or charge. When i plug it in, it just gets hot, but there is no sign of life. I tried holding the power button and entering recovery and download mode. But its not recognised. I dont think its the battery because when i plugged it into a pc without the battery, it still wasnt recognised.
Before this happened, i was running the solo launcher and i was using a kindle paper charger for it.(first time i used this).
Please help me find a way to fix it without jtag. Usb jig won't work, its totally not functioning to anything except getting hot when plugged in.
Signs of life:
Gets hot when plugged in.
sadly bro,but it sounds like a motherboard is dead
if you have access to usb jig - atleast try it
if no joy - motherboard replacement

oh ok thanks, i am not under warranty, so could i just send it to a local repair store, or do i need to send it to samsung. If so, how much would it cost?
sent it to your local repair shop - it will be less expensive than samsung's service
you can also buy the mobo at ebay etc,and pay only for the procedure
idk about the price,mail the repair shop about that.
USB ports
When my phone was newer I had a lot of usb port trouble, overheating, failing to charge properly, even apparent bricking. I heard there was an issue with this port. I narrowed it down by sticking a small object into the USB port and levering the pin slot back up to the middle (preventing the short).
That fixed it for a while. Also fluff can create a short, so blowing it out can fix it.
It finally failed again, so I bought a $5 piece from ebay, watched a youtube video and fixed it properly.
So, try firstly blowing out the usb port, then using a toothpick to push it around a little. If that fixes your phone then all good
Yeah, that'll fix it
