screen wont turn on...

i dropped my phone and since then the screen refuses to turn on. it seems like everything is working fine except the screen. calls are coming through and im able to answer the call as long as i swipe at the right spot. is this something that can be fixed instead of swapping out the phone? if this cant be fixed and i have to get a new unit, can the sprint technicians be able to somehow transfer everything over to the new phone? btw, my phone is rooted with cwm installed and nandroid backed up to internal storage since i have no sd card installed.

If you can connect via USB you can grab the data from internal storage possibly, but it sounds like, at best, your display has a hardware issue ( strange that the touch works but the display doesn't)
But I see a trip to the phone store in your future.
If you can, I'd recommend booting to the boot loader (pwr-voldown) and using Odin to flash a stock from first so you can at least have the chance of getting a warranty replacement. ("Not sure what happennes, the screen just doesn't work anymore...")
Good luck.

Sounds like something with the connection between the LCD and the motherboard. You could get lucky and only have to reconnect the LCD's ribbon connection, however, if the LCD is cracked in any way, it would have to be a replacement, that is, if they allow replacements on cracked LCDs. Every ASC location is different. The only way to transfer anything would be to connect it to a PC, like he said in the above post, and hope it connects as USB storage by default. Copy everything to the desktop and then drag-and-drop onto the new phone's storage. But dude, get an SD card. It really makes EVERYTHING so much easier when transferring to a new phone.

The LED back light system and the touchscreen are independent of each other. Sounds to me like the connection to the back lights and the power got disconnected.

that is exactly what it seems like. can i take it into a sprint store and have it repaired or do i need to send it off?

As long as there is no physical damage then I would say its repairable. If you have ever seen a smartphone dissembled you should go check it out on you tube. Alot of the connectors are very small and easily popped out.

[Q] Why is my galaxy nexus w/ black screen read by ADB as device not found

I have a galaxy nexus, uses the Eclipse-2.1-toro-build4 rom (old I know, but it was smooth and worked for me, so I kept it).
Last night, after keeping it in my backpack during a bike ride, I went to go use it. The screen is black and I noticed a few solid color black lines running through the screen. Screen is likely dead, my guess.
I am able to boot up the phone fine. I see the L..E.D. notification light come on, and when I get new emails (I left it on wifi the last time I used it), I'll hear notifications...
But, when I try to connect my phone through usb and attempt to connect to it via adb, I'm getting a device not found. I've connected my phone dozens of times using this method without a problem.
Anytime I issue a command with adb from my computer (ubuntu 12.04), it gives me the device not found although the device is connected via usb. This happens even when the galaxy nexus is displayed in nautilus, so it's clearly connected to the computer.
Any idea how to access my sdcard with adb then or to troubleshoot why it's not being read?

Does your phone have a screen lock? Try pressing the power button to unlock it and see if you can find the unlock button (assuming the touch screen still works). If you have a pin, it might be quite hard to get it
I can't access adb whilst my phone is locked. I think it is a security measure.

HTC One X with black screen but working charging LED, Softbuttons and MTP Access

Hi everyone,
first off, I've spend days now trying to find a fix. If I've missed anything, I'm sorry, it wasn't for lack of trying.
Here's the situation: I have acquired an HTC One X earlier this year which has worked quite flawlessly. I went ahead and unlocked the bootloader and installed a custom recovery. However, since I handed the phone off to my not-so-techy sister I did not use a custom ROM, and after the HTC update failed with the custom recovery I reversed that as well. The device should now be stock everything with unlocked bootloader.
After a few months my sister encountered heavy problems, though. She described them as battery related (wouldn't turn on correctly) and eventually she moved to a new phone. Now I have gotten the device back and I am trying to fix it. After charging it I managed to have it boot once. However, I but it to the side and wanted it to load some more. Ever since then the screen doesn't come on. The charging LED seems to work fine (eventually switched from red to green, too, indicating that the device is fully charged) and the button backlight still works, too. Most significantly though, the device is recognized as MTP device in Windows: I can access all the data in the storage without problems.
I have read that there is an issue with the HTC One X and the display connector so eventually I went ahead and took the device apart. It's lying in front of me now in pieces, but I still couldn't get the screen to come alive. The obvious conclusion would be to buy a new screen but the device doesn't feel like it's worth the investment. Besides, I would like to know for sure that it's the screen before I do anything.
So I turn to you guys and ask if you have any idea how I could access the phone via my computer. I tried to boot it up in bootloader mode but due to the strange standby methods HTC is using and not seeing anything on the screen I haven't been able to do that yet: Whenever I connect my USB cable it's recognized as MTP device, not ADB. Debugging seems to be deactivated so that doesn't seem to be an option. Does anyone have any idea how I could get the phone to talk to my computer (i.e. get into the bootloader or ADB screencast for sure)? With my Galaxy S I could simply plug in this dummy micro USB and would be sure to end up in download mode.
Any help is appreciated!
tl;dr: HTC One X screen is dead but LEDs work, is recognized as MTP device. How to make it talk to the computer?
Thanks,
rien

Alright, sometimes just posting stuff like this helps already. I was now finally able to get the phone into fastboot (apparently) and it's reacting to the fastboot commands. I suppose the next step is to load CWM and connect via adb. This way I can at least do a factory reset.
Does anyone have any ideas regarding the original issue with the screen? Especially since it does seem to work occasionally. And doesn't show any fragments...
Can I enable USB debug mode from within the recovery to work in the system?

5T with broken/black screen - need help switching to MTP

Hey XDA Family,
I've been searching everywhere even here but I need help. My phone was dropped and the screen is broke/black. It still works as I can receive calls and able to answer with headphones. LED lights still work.
I have previously enabled USB debugging but never switched to default USB behavior to MTP. It's set for USB charging.
My goal is to use Vysor to view my phone screen and kinda-sorta semi use it temporarily until I can replace/fix it.
Some other tidbits - it was powered off and on - so it's on that initial screen where it requires Pattern Unlock.
Am I SOL? ADB doesn't recognize any device (and it won't because it's not in MTP mode).
Is there any tool I can use to force switch to MTP? I read stuff about Miracle-box.... not sure if that will work.
Any help will be appreciated.
Thanks.

I am still stuck. I tried ADB once again but still no go.
Even if there's a way to factory reset the phone so that the lock screen is removed may help. Remember, I have no screen. to view.
Has anyone heard of an OTG adapter that has an HDMI out so that potentially I can connect a monitor?
Thanks again.

Through Fastboot/ADB
If you have TWRP installed (command line should work if recovery doesn't work) it sometimes gives access to the storage when in recovery mode (hoping you don't have a password). If you turn off the phone then start into bootloader (power + volume up) then from your PC use the fastboot commands to restart in recovery (https://tektab.com/2015/10/31/android-bootloaderfastboot-mode-and-recovery-mode-explained/).
Once you think you're in recovery try to connect the USB and see if it picks up the storage.
If that fails you can try to do the same stuff using the adb commands instead of the fastboot commands, it's a little trickier but i think you should be able to use an adb pull command to extract the files from your phone, if you get it to work then you can also reset the phone to factory through the commands. This way you won't give whoever is fixing it access to all your data.

If the phone itself isn't broken you can always order a replacement screen and either replace it yourself or have someone who knows how to do so, unless you had planned on getting a new phone.

Thanks, I'll try that and let you know if it worked.
I wasn't planning on replacing my phone... just fixing the display.
It's been a week now and I am still trying to scrounge up the cash to get it fixed.
Anyone know how much OnePlus charges for an official replacement? I have a phone repair shop nearby that quoted me $155 (USD). Seemed a bit pricey.

I'd see if you can pay them to just install the screen, I went to a local shop about a year ago and they charged $35 for just the labor, as I already had the parts.The screen is like $150 or so on ifixit, which is about right for an OLED like the 5t has.

Question Screen not working unable to get into the phone

Hi, I need help and looked almost everywhere for answers. For the past few days, I've been trying to recover the photos and videos on my phone. The screen went completely black last week and I've restarted it thinking this would fix the problem. It didn't and now I can't even get past the PIN unlock. The phone still works when connecting with an HDMI cable, but I'm unable to get past the pin unlock.
I tried using an HDMI adapter hub and connected with a keyboard to no avail. The keyboard powered on, but anything I tried pressing on my keyboard the phone didn't respond to the keys, numbers, and all. Also even tried using a mouse.
I also tried using Samsung Dex, but I just couldn't get past the startup PIN.
What can I do to retrieve my files?

A data recovery specialist may be able to retrieve them.
Always regularly and redundantly backup critical data.Another disadvantage of not having a SD card slot as it's data if unencrypted it would by accessible

Thank you for your kind response. Would it be possible to have the screen fixed then I'd be able to have a working phone?

You're welcome.
Perhaps. That may increase the risk of data lose though. If it was me I would have written the lost data off already. I've lost a database that was 30 yo and not replaceable. Some lessons are learned the hard way.

Man, that's a terrible and awful lesson to learn. But you are right, that's the hard way. I'm going to try one last thing, I can't give up, I'm going to purchase a wireless keyboard and pray that I can type my pin in.

You can also connect a USB mouse, but then you have to find out where on the screen the numbers normally appear.

I'm thrilled that my solution worked! I'm now using Samsung DEX in combination with a universal adapter hub, a wireless mouse, and keyboard, and transferring files to an external SSD. I am grateful for the advice provided by others.
Edit: After further exploration, I've realized the solution was even when the screen was black. I can still swipe up and type my pin blindly while using Samsung Dex. (The screen isn't active when not in Dex, but in Dex, it works somehow.)
Edit2: The only way to get past my pin was to blindly type my pin like this the way to get access to my phone data was to blindly accept the access from computer. (I say blindly because I could not see the what I was pressing and it was just through memory that I was able to do it)
Edit 3: If you are suffering from a dead screen issue and are unable to access the data from your phone, there is still hope. But first, you must remember your pin and where each press goes. Although you cannot see your screen, swipe up (this would allow you to type your pin). Type your pin, and if done correctly you have unlocked your phone (although you cannot see this). You should however be able to access your phone through Samsung Dex, see your screen, and access your files. Sometimes Samsung Dex just doesn't want to work. It's okay, now, connect your phone to your computer. You should see your internal storage. If not, then your phone is asking permission. (You can't see this) Simply tap on the bottom right of your phone to OK the permission. I hope this was helpful. Thank you
Some notes; a day before my screen went completely black, the top half of my phone was not touchable (the touch screen just didn't want to work.) I was very lucky the bottom half to type my pin was still working even though I could not see (just through memory).

Kindly change the thread to SOLVED thank you
