Hi everybody, I need all of your brains, because my brain stuck at this point.
Yesterday I got a phone (Samsung Galaxy A3 or model SM-A310F) from my neighbor with an damaged display. He told me the phone fell into water, but run after drying normal (I saw a video, isn't the phone water proof?) but then it fell to the ground and since the phone doesn't recognize any touch. I checked it and told him that I need to take a look inside because the glas is in a perfect state, I could see anything on it but, as I said, no functional touch. Hard-Keys are working fine.
The first thing what I does, was to restart the phone with "Vol- and Power". I thought the phone were now bricked, because the boot-up seems to be endless. After I let the phone work for approximately 5-10 minutes, the Samsung logo comes up and Android was there but again, with no touch.
So, as I said, I opened the phone, took a look inside and was very confused, because two wires were broken and some electrical parts near the display plug and the plug itself had a white covering, I think from the water damage before. Anyway, the phone is running but after I opened it, the screen got black and never come back. I cleaned up the parts and the plug and tried again, now when I press home or power, the screen is flickering on the left for a short time and is then black again.
At this point I said him that the phone is broken, because it is not clearly if the screen is broken and/or the mainboard, too (because of the white covering).
My neighbor asked me to recover the files and the contacts. I told him it is hard, but not impossible. My plan was to install a recovery, boot into and to adb pull all the files to my computer.
But: USB Debugging is DISABLED and the oem lock is on, too, so I failed trying to install twrp with odin. I just get a fail.
New for me: you can control your phone with your computer mouse and keyboard, so I thought, I can just accept the MTP request and simply drag and drop the files... but nope, the request just pops up, when I connect the phone to the computer. So I can't use my keyboard AND the connection to my pc...
Adb doesn't recognize the phone, because of the disabled usb debug (and even if I can figure it, I need to accept the debug dialog while connecting).
So, this is your part, anybody, any Idea to install something or just to recover the files?
My ideas:
Mirroring APK (to mirror the screen to my PC, explored that with MyPhoneExplorer)
Custom Recovery for stock recovery flashing (flashable zip)
Downgrading (but will definitly stuck in a bootloop, because I can't delete the data)
...
What do you suggest?
Buying a new screen isn't an option. I don't know anybody who can "borrow" me his screen.
I'm really a android geek, not someone as you are, but more than "normal users", so if it difficult, it is not a problem.
I also accept some tips with the screen part. I attached the picture, which I tooked for him. There you can see the white covering AFTER cleaning (it is almost there at some spots... I don't want to break more).
Thank you alot!
Kisses from germany =)
Sorry! I posted it in the wrong sub =( Can anyone please move it?
Ah I would like to update this thread:
I bought a new display, had some problems anyway but now I got a new phone =)

Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance
Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]
Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you
actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something
Hi. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.
My Xperia fell today and when I picked up I saw the screen was broken (im talking about the inner part which is the LCD I believe)
Its kinda like this [Seach on youtube "My LCD Xperia X8 Cracked" since I can't post links ] (That is not my device but the problem seems to be the same, even tho on mine its only a small part (just the top edges))
Everytime I turn on the phone now it just shows the lanes then turns itself off.
Is there any way to fix it? If so, would I have to buy a nex LCD? And if so, would it be hard to change it myself? I live on a small town and trusting your device to some technician is like giving away your money.
Thank you ^^

Thank you for the fast reply. Yeah I think I'll try checking my warranty even tho I believe is off warranty already as I have this device for over a year now.. I'll prolly end up changing the LCD however, is it sure that changing the LCD will fix the problem or it might have another broken thing inside there? Today I just tried to turn it on and it won't even turn on now it just pops the red LED when I press the button (I think it ran out of battery, but then I try to charge it and it won't).
Thank you again

I have the same issue every time the phone dies from lack of battery. after poking it a bit on USB (connect it for 20-30 times) I saw that the device sometimes switches on in Flash Mode and after a while, FlashTool wil recognize it and do s strange thing. It allows you to start flashing what you want but after starting to gather device info, it freezes. after doing this a few times (10-15 times) Windows recognizez new device and the FlashTool asks to choose my device. Then the phone reboots and starts up in Android.
Usually this works and phone starts to charge but today after it started it was not charging and the batt level was saying Batt 0% and that it won't last if unplugged. I've left it like taht for an hour but still nothing. Then I decided to reboot the phone from the power button menu and after restart it started charging. It took a while but then it returned to normal and now it works again.
I have this issue only on custom kelners both NAA and ALFS but it's ok on stock kelner...
It would be great to find a fix for this as it is very annoying and time taking just to make the phone start charging...
Actually I charge mine via USB connected to my PC everyday (as its more comfortable) but I tried to charge it with the regular charger plugged in to the wall's socket and it charged.
I guess I'll buy a new LCD and try to change it myself.
Hello Everyone!
So i'm really stuck over here. I have an international Samsung Galaxy Note N-7000 that is working but with a black screen!
First of all i want to discuss exactly what i have done:
1.i had a problem with the charging port where it works sometimes and most of the times doesn't. So i decided to order a new charging port to replace the existing one.
2. When i received the new charging port i instantly started to dissemble the device (The device was working perfectly before starting replacement)
3. After i removed the old one and installed the new, i turned on the device and it showed only a black screen, then after some time i saw the touch buttons light, but still the screen is black:crying:
4. so i decided to return back the old charging port and this time when i turned on the device it sounded like it's booting and working but still with a black screen. The phone even received call and the touch screen is working but with black screen.
What do you guys think has just happened to my phone? could the new charging port cause any problems with the motherboard?
i'm really stuck and don't wanna go to a service center
I have recorded a video of the problem. Please see it below
since i'm new over here, i'm not allowed to post youtube link.
please head to youtube and type my username and watch the video : nadeaa0a
thank you very much
My younger brother always liked to disassemble things with a hammer wondering after why it wasn't possible to assemble it the other way around.
It took him a few years to understand that real knowledge of things is a clear advantage.
Go to a service center and get help from a professional instead of making it ...

maybe you disconnected the wire you were changing ports ! don't worry and don't freak out just take to any shop and they will check it i don't think the screen is burnt because if it was it would be more expensive ! go to any shop and ask them to change ports and check the screen
for what you described, my best guess would be either you unplugged the lcd and didnt plug it back in properly.... or you damaged the flex for the lcd... the charging flex wouldnt cause the problem... just inspect the lcd flex and plug for damage... if no visible damage plug it in again and try it again... lets hope its just not plugged in right...
I have the same problem
Hi,
I have the same problem. I had never disassembled my phone and the screen slowly turned purple and started blackening out. It was fully functional. This I knew because I connected it to my Windows 7 computer and used Android Commander. I ordered a new screen complete with bezel etc. I have two batteries, the first didn't even charge after I put it in the phone (it had drained totally during the wait for the new screen), the second was partially charged and allowed the screen to boot. It is however behaving like the first screen did before it went black, that is purple. I am sure I have not done anything wrong with the connections. Could it be the batteries? or the adapter flex? I just hope it is not the mainboard. It is not on warranty and we don't have that many honest phone specialists around where I live. I am almost sure others have experienced the same problem and someone on xda knows what the problem is. If you do I would be indebted.

it shows as color black, or nothing (like locked device)? I used to face this problem too with my infuse 4G, but it was because of installing custom rom. Had problem with few rom i installed but nothing happen on my stock one. If your device is just not lighting up(like locked device), then i guess because of ROM, but i'm not sure yet. But if it shows "color black", then i don't know.
THIS IS NOT A SOFTWARE BUG. Its the Screen flex or the ribbon. Disassemble the back part, and take a look at the flex or the ribbon connector of the screen, clean the conector with a tooth cleaner with alcohol and let it dry for a few minutes. Put it back on and mount the back part again. Test it, it should work.
Same thing here: changed the usb port, booted fine, had issues with the sim, turned off took it apart again to check, put it back on and black screen.
Yea having the same issue here, dismantling the usb module and put in new one, power up black screen!! The menu and back button did lights up, and the phone is working too, can hear the booting tone, anyone got any solution for that yet?

I have unplugged and replug back few times, same result. Guess most probably i have damaged the flex cable. Replacement part seems too pricy to change, rather buy a new phone.

Hello XDA,
So a Moto X 2014 was dropped from the height of a couch to a carpeted floor earlier today (my friends moto ). He picked it up, inspected it and then resumed using it after seeing no evidence of damage(no cracked screen). Next he turned the screen off. After a bit, when he went to turn the screen back on, it would not. The haptic feedback still works when hitting the home key and other parts. I can even drag up to get to google now, then start typing into the search bar. All of this is done by feel, without the screen being on at all. Also of course "ok google" works too. The phone also gives sound feedback. So now you guys get the picture here, only the screen does not work, and the digitizer does. I have two questions here:
1. How?
Why on earth would the phone still work until the screen was turned off?
2. Is there any way to fix this?
My hypothesis was that the display connector somehow became ajar due to the drop, which would require a teardown, which we will not do. Would a battery disconnect help at all. I think we may be willing to risk peeling off the back to disconnect the battery.
The phone is most likely going to to be returned, however if there is something we can do which might work possibly via software on the computer that would be great.
Thank you XDA so much for your help!

Enter boot loader. Turn off your phone and then press enter and volume down. After that with the volume down go to "factory" and press volume up to select it. Your phone will restart with out radio signal and a Commserver app on your status bar, there you can select the first option and check all the system hardware. Hope it helps.
Regards
I can't access the bootloader because the screen will not turn on. I would not know what I was selecting. That is the source of the problem. Thanks though.
Is there a way to do a factory reset over usb with adb? Also I cannot find the required drivers.... anyone out there?

Yeap. But first download minimal adb and Fastboot drivers then search for the firmware of your phone
The command is
Fastboot flash system system. img
I think you need to unlock your bootloader in order to flash even stock system files
Since you dropped it it is rarely possible that software is "broken" better to do is sending to motorola asking for warranty (if no signs of drop are visible) an hope.
Hello
I have purchased a p30 pro recently. Yesterday, while using phone, suddenly the screen colors got washed out, then after some minutes the screen went full black. I believe touch is working, just the screen sometimes draw some subtle vertical lines and no image appears.
I'm not much concerned if the phone works or not in the future, but i have very important files in the phone that i need to retrieve and i believe if i send the phone to a service center it will be reseted.
Any suggestions of what i should do?
I've tried:
- Pressing the power button 20 seconds while phone is connected to tv whith an usb-c - hdmi adaptor. Huawei logo appears on tv but after that screen flickers with black. If i was able to have the pin screen there would've been great as could install an app to send fles to cloud after.
- Tried with the PC suite HiSuite, but since mobile is locked with pin, it cannot connect to do backup.
- Tried to insert the pin in "blind" by touching screen
Would appreciate if someone could help. Is there any way to enter the initial pin to have access to mobile, but without using screen?
Thanks
P.S. Phone didnt felt or anything, just subtedly washed on the faucet with just water as it was bit dirty (like 10 hours previous to failture). Wasnt submerged either. Will try to put it on a rice bowl eventually, but an IP68 phone (Pro) i find strange, i have done that several times on my old S8 and never had an issue.
Phones are NOT waterproof. Have seen several liquid damaged iPhones and Galaxy phones. Most likely the phone is liquid damaged. Second likelihood is damaged display. Rice will make it worse. You’ll need someone, a mobile phone repair technician, to open it up as soon as possible and remove the corrosion with IPA or an ultrasonic cleaner. The longer you wait, the worse the corrosive damage becomes. Look for a shop that's competent enough to remove the rear glass without cracking it. Franchises are generally less reliable.
You can use HiSuite to retrieve files or even preview the contents of ur display , thing is you have to find a way to press the accept button for the usb authorization when asked from the phone.
EDIT: Just saw you used the method but your phone is locked with a pin so i would suggest to try the blind method to unlock the phone.
Solved, thank you all
Was able to unlock and backup everything, was lucky
