I've got an LG V20 (H990ds) with a damaged screen and/or main board. I want to recover data from it. The phone is encrypted. I know the PIN, but can't enter it.
I think the phone got some water in it. The screen comes up black, though I can see a bit of backlight, and get sounds that suggest it's functioning normally except for the screen. It has come to life further since it was damaged, with the display working, but not the touch-screen functionality, and on one occasion with full functionality. Unfortunately I didn't back up then, and it now won't come on at all.
I've bought another of the same model phone. Can I take the phones apart and use the new screen to access the data on the old phone? Is there a guide somewhere I can use for this?
Where is the internal SD card? Is it in fact a detachable item, or is it built into the main board? If it's the main board on the old phone which is damaged, what are my options?

If anyone can offer any advise/assistance, it would be greatly appreciated!!
I have 2 AT&T branded 8525 phones. Both have issues and I assumed I could make one good working phone from them.
Phone 1 had a touchscreen issue. It is not responsive what-so-ever. I tried the credit card trick, cleaning out the edges, hard reset, soft reset, etc... nothing seems to make it respond at all. Reflashed the ROM, but of course I am stuck at the "Touch Screen to Begin" screen.
Phone 2 works just fine, but when plugging in the mini usb charger the screen starts to fade to white (with many vertical lines appearing...but eventually the screen goes to white). If you wiggle the charger, it will clear up, but then go back to the fading white screen. If you leave it long enough on the white screen, it will lock up.
So I thought I could take the known good LCD from phone 2 and put it in phone 1. Yesterday I took both phones apart to do this. I placed the good LCD in the phone that had the possibly bad LCD. Put it all back together and found the touchscreen still does not work . So perhaps the LCD was fine and it was something else. I then decided to just take the motherboard from phone 2 and put it in phone 1 along with the LCD I just replaced (effictively moving the lcd and motherboard over to a new case). Same issue... touchscreen does not work. I assume moving the parts around eliminates a loose connection of some sort. I did make sure the ribbon cables were properly aligned and secured well. I am guessing something is wrong on the motherboard.
Does anyone have an idea of what could be wrong to prevent the touchscreen from working?
Oh...moving both the motherboard and lcd with the whitescreen issue(phone 2) over to the other phone (phone 1) casing didn't change anything at all either...so I assume that is not a connection issue with the cables. I also looked closely at the mini USB connector on the motherboard to see if there was bad solder or something that was making it act up. I am guessing bad hardware in both phones, but was hoping I could somehow make one of these phones work and junk the other. Sounds like I may have to junk both as the cost of parts is probably is silly.
Thanks for any help!!

I've got a Samsung Focus that no longer has a working display. It seems the rest of the phone functions perfectly, but I'm unable to see what is happening. I think the display is recoverable, but I'm not positive (it's almost like there's no power being sent to it).
So when I connect to Zune software, I'm unable to view my phone contents because I have a lock pin. This becomes problematic with a non-working display. So one solution to my problem is how can I remove this code OR factory reset my phone without getting screen conformations.
Secondly, would it be worth an investment to repair the screen by buying a new one? It seems to be about ~$130 online for new displays and I'm very comfortable doing modifications like this with mobile devices
Thanks!

What I suggest is read the diagnisis codes thread and see if you find something useful there (code, advice). Personally, I haven't heard of any code disabling the screen but there might be one. The hard reset combo from the wiki should cover that too, I think.
Now, that being said, I see 3 possibilities, higher probability first:
1. screen is damaged (and/or possibly something else). if it's broken, you can confirm.
2. screen connector/cord is loose (should be easy to fix)
3. software/code issue
1 is hardware repair
2 is easy fix, still hardware
3 is easier fix. here, you need a secondary phone, identical. you can perform the exact steps side-by-side to copy/make sure you got it right.
I know it's not a loose connector issue. I've triple checked that and have rubbed it all down in alcohol to make sure it wasn't a dirt issue. I also cannot do anything that requires the digiplex as none of it seems to be registered.
Things that work for sure:
Sound (internal speaker)
Power Button
Volume Buttons
Touch buttons on the front at the bottom (by windows key)
So the screen doesn't work but it's not broken?
I have a Galaxy S5 that belongs to my brother which has a cracked screen. It powers on fine and recently factory resetting itself but can't see the screen. I'm trying to recover photos from the device of my brothers son during the first year of his life. The photos are very important to him and I'm trying my best to recover them.
I'm using MobileEdit Forensics and other recovery software but having problems connecting to the device. I'm thinking it's because of USB debugging isn't enabled. Is there a command of the line code I can run to enable it?
Would replacing the screen be any benefit to me? Am I taking the right approach?
Thanks in advance for any help given.
Do you know if touching any part of the screen has any effect (even of you can't see what touching it does)?
Replacing the screen is an option, but it's an expensive option if there are other things that might/could work instead.
The reason I asked about whether the screen is still responsive is because if it is, you can simply get an MHL adapter from somewhere like ebay and use it to connect your device to a TV so that whatever is on the phone screen (even if you can't see it) will be on the TV screen. Then you can perform the retrieval from the phone by looking at the TV screen.
The MHL adapter I got to use with my phone cost me £5.
The galaxy s5 don't have a digitizer so probably if the screen is dead,then the touch function is too(as I know from my brothers note 3 witch has the same mechanism for the screen).
You said you did a factory reset on the phone.. If you did, wouldn't those pictures be deleted?
A good option is to try Samsung back up (I think it backs up pictures too) or other back up software the phone may have..
Another thing to try is if the phone have adb enabled then you could unlock it by:
Powering it on
Let it auto connect of to a wifi you have already given the password for it when the phone was workings (if WiFi was enabled last time the phone worked)
Log it to Samsung website and apply the'unlock my phone' option
Then connect it to the PC and obtain the pictures...
Tryed to see if the pictures are located in the SD card?
If nothing of this works then the only solutions remaining are repairing the screen or get it to a data recovery company..
Hope I helped you and good luck with it
Uh...The S5 *does* have a digitizer....In exactly the same way that *every* other touchscreen device ever produced does.

It doesn't.. It reads touch events directly from the amoled screen.. The digitizer is just a glass for the s5.. It does nothing, the phone can work too if you just remove the glass and it reads touches normally
The digitizer is the part of the screen that tells the device *where* the screen was touched ie the 'grid reference' of the interaction. If the S5 doesn't have a digitizer, what replaces it...without the digitizer how is the S5 going to know what to do when you touch the glass at a specific point...which app/function is being selected at any given location on the display if the device can't tell the location of the touch?
---------- Post added at 09:01 PM ---------- Previous post was at 08:51 PM ----------
The digitizer part of the screen exists...pure and simple. It is usually bonded to the underside of the outer glass panel.
If as you say, the touch works without the glass, then it's built into the amoled display....but it *is* present and a part of the screen, regardless of what part of the screen module it's built into.
That *may* well have implications for the touch functionality.
If it's just the 'backlighting' that has failed, but the touch functionality remains, then connecting the device to a TV via MHL should work.
If the screen is totally dead, an MHL connection will be pointless, and a new screen is probably the only option. But as has already been mentioned, if a factory reset has been performed, the chances are that what you are trying to recover has already been erased.
Alright, long story short... I've been a user of a D-802 for the last 4 years. I was unlucky enough for the phone to be dropped from 2nd floor at work (don't ask how), the panel housing the screen is bent in right upper corner, which ultimately means this; I've fixed the screen two times, for it to be broken in less than half a month. Even more so, I ordered a new screen a week ago and it broke because of the bent frame 10 minutes after fitting the screen, as in, simply putting on the rear plastic cover, which broke the screen and the flex cable. Took it over to a repair store, they told me the phone has a broken cable on the screen and a new screen costs 90 EUR (not really worth considering how old the phone is.) and the motherboard was damp, too.
Now what I've got is a glorified brick. It turns on, the screen is black/non responsive to touch and it's stuck in file transfer or charging mode. Not really a problem, as I was able to retrieve all the photos from the phone through USB connection, however, what I'm really after are the phone contacts in there. We're talking about 3+ year old contacts that have a monumental value to me and I'd see gladly see them backed up.
Now, the reason I hadn't backed the phone is because it's rooted, obviously.
Out of ideas so far, will be eternally grateful to anyone with suggestions.

I think the easiest way is the same way you rescued your photos from internal storage. Search the system partition for database files like contacts.db or other *.db-files. One should contain your contacts.
Good luck! :good:
Thanks, but no luck on that behalf. Already tried that, also didn't find much luck with adb or other software, as it all requests USB debugging to be turned on.
I have a Mi 9T that took a dive on its corner breaking the display which has degraded from unreadable half a display to black while being tasked to recover some data. Due to the phone not being used afterwards investing in a new screen is not really worth it but due to every option for me to see what is actually happening on screen and every option to remotely retrieve data is turned off it seems to be the only way. Now there are both AMOLED and LCD screens available, but it is not really clear to me if a LCD will just work directly, as it has no fingerprint scanner and probably different drivers.
They are half the money so if it gets me a working screen to enable remote access it is all I need.
Maybe have a repair shop retrieve the data be a better option. Any impact hard enough to damage the display can damage the mobo too.
Always redundantly backup critical data...
I just wanted to know if the display is an option, before I order one and take it apart to see if there is any more visible damage. It is not critical data, hence the cheapest option to retrieve it is the last resort at the moment. It should have been back upped but for some reason it turned out some stuff was not the last month or so.
It does still work, as I'm waiting for the battery to die and have an alarm go off twice daily. Wish it would just turn off instead of reboot with the power button.

Is there any knock-off screen that is advertised for redmi k20 but is definitely an LCD judging from price? If there isn't, then other screens for another phones probably aren't compatible (different connectors, different drivers, etc)
Also you need heat and prying tools, and screwdrivers to remove the mobo so connect the new screen.
Yes, it is listed as LCD on aliexpress for the MI 9t, pro and K20. They also sell the oled display but as the phone is going to be sold for parts I'm going for the cheapest option and just hook it up and not glue it in.
Disassembly is not an issue, it's not my first (and probably not my last). I just don't normally use different parts than what was in there.

If it was cheap enough you may try it, if the data is important. But note that the screen is quite fragile, and you probably want to disconnect the battery from the phone when trying out the screen after it has powered off.

Disconnecting the battery is something you should always try to do as soon as possible when working with electronics.. The good old day when you just popped it out...
My plan was to put it back together with the new screen but not bother with gluing everything in, try to pull the data off and then wipe it.
If you are from EU countries you can buy, plug it, get data or set it to work remotely with PC and send it back to get refund

It is turned off. And in what universe could we turn it on without a new screen?lol
