Hello guys. I have unbricked the D800 using "very partition method" and it worked, I have download mode again. Stupidly enough after I fixed it I applied "very partition method" again because I was trying to get my PC to recognize the proper drivers. After that the screen went dark but the phone is working properly, I have flashed a rom successfully, although I couldn't see anything on the screen I knew I was in download mode because the correct drivers where diplayed on windows device manager. During boot I see the LG logo for half a second and when I press power button I also see the screen for half a second (asks to insert sim card) but then it goes dark again. It boots up normally, double knock working, touchscreen working, makes sounds, charging etc. I don't know if this is a hardware problem, maybe a short circuit caused some damage on the motherboard? or if it is a software problem. But apart from that the device seems to be working fine. Any help appreciated

I have obtained a water damaged Lumia 520. I opened it up and dried it while also clearing any oxidation from the various contact points. The phone displayed the bolt+gear icon on screen but the screen kept flashing and fading. I figured the phone needed the firmware to be reflashed so I downloaded the software recovery tool and it detected the phone and flashed the firmware without error. Then the phone actually worked albeit with a black screen, I could hear the little noises and stuff so it was working under the black screen. I figured that maybe the screen could be salvaged by cleaning the contacts and letting it dry up completely, but after I put the phone together it wouldn't work anymore at all, it basically turns on for a few seconds and turns itself off. The software recovery finds it and I can reflash the firmware but it still doesn't work. I tried checking all the internal connectors but now there doesn't seem to be any way to make it work even with the dead screen.
Is there something I need to touch on screen to make it work? I never had a Windows Phone so I don't really know and I can't see the screen. And do you geniuses know what might be wrong with it and how can I tell if it's just the LCD that has been killed by the water or if the motherboad might be FUBAR as well? What could be causing it to turn off after a few seconds? The battery is definitely not dead as I left it to charge for a long time.
Actually I just managed to "fix" it. The screen comes on after I cleaned the contacts and messed with it a bit, it just looks really bad and it's full of line but I can see what's on screen and use the phone. My issue now is that the bolt+gear icon appears at every reboot and doesn't go away. The only way I have to boot the phone normally is to hold camera and volume down after I reboot it. What does this mean? Other than that the phone seems to be working perfectly once it actually boots.
I just managed to bring it back to life completely. Screen contacts were water damaged but I managed to get them working again and now the screen is perfect. It kept getting stuck on the bolt+gear icon after every reboot because the volume+ button was stuck but I managed to unstuck it and now the phone is perfect. So yeah if you have a flashing screen after water damage check the contacts, if your phone doesn't boot and keeps getting stuck on that icon try to unstuck the volume+ button.
Question 1. This just happened right now my s5 is starting up and sometimes it shows the s5 startup powered by android sometimes not after that it proceeds in starting up with the usual sound effects but the problem is the screen is just plain black. Now i believe my phone is proceeding to the homescreen cause i tried to ring it and it did plus my ringtone music played. I tried pulling the battery multiple times and start the phone but still same result. I also tried the taking the battery off and pressing the power button for a minute. also tried the safe mode, but none of them worked. What do you think? is it a firmware or a hardware issue?
Question 2. Im still not sure the cause of the problem. Because of the black screen issue i I wanted to backup my files saved in the phones memory. However my phone is locked through my fingerprint and I guess because of that when I connect my phone to the pc im unable to access my files. Is there anyway I can access my files through a pc and unlock it using my phone's fingerprint alternative password?
TIA
If the initial logo sometimes won't show up, it sounds more like hardware as that is not part of the ROM
If your phone is secured by fingerprint, wait for it to boot, press the home or power key to wake it up, then swipe like normal, if it's just a faulty screen, the fingerprint swipe should still work

hey thanks alot swiping the through the black screen unlocked my phone. so do you think it is a hardware issue I assume its the LCD?
but if ever the LCD is broken , the finger scanner should also not be functional? or im wrong?
The finger scanner is a separate button (Home button)
There are two parts to the screen iirc, the digitizer (Touch) and the panel itself for displaying, could be just the panel if the digitizer is still working
You can use this to control your phone without a screen, might help

i'm experiencing the same problem again. Before I guess after 40-50 restart I was able to open my s5 with a screen, but now it happened again and the difference is that when I boot it the "Samsung s5 powered by android" rarely shows and it will proceed until the home screen with a black screen?
i have already removed the battery, charged it, changed battery, boot it in recovery and safe mode but still all i'm getting is a black screen.
Any idea how to fix this? Is this a hardware issue already

Hi kenchii17
As you didn't provide answer to @*Detection* 's suggestion for backup, here comes another:
[TOOL] Tickle My Android
To get rid of all this inconvenience, I would suggest a complete reinstall. Clear everything through Recovery and then flash a new Stock ROM via ODIN.
Nice regards.

Hi,
unfortunately I have a problem with my Galaxy S5 running CM.
Some days ago, the power button got stuck in the case so that it was pressed for quite a long time. When I tried to turn the phone back on it only showed the logo for a while, vibrated and rebooted.
I tried to boot the phone in safe mode which didn't help and then in 'transfer mode' (sorry, I don't know the right term. I think it's the mode where I transfer a custom ROM). The latter without connecting to a computer so it said something like 'transfering, don't turn off' for a while. Eventually, I had to turn off the phone cause nothing happened.
Now, when I try to boot the phone it just vibrates and stays black. Not even a LED flashes. When I connect it to my PC it vibrates and the PC recognizes something but doesn't show any connected hardware. It just installs a driver.
People at a repair store said the screen is dead but I don't really believe it because there was no physical damage of any sort.
Is there a way to repair my phone?
If you turned it off mid flash you have no ROM. There's nothing to boot. Use volume up, power and home while booting. Load recovery. Flash the ROM and don't stop it. If it doesn't work get a different ROM and try again
Hey, I broke my op2 screen so I bought one from ebay, teared it apart all correctly (i'm a computer technician), installed the new screen, all fine but a weird symptom appears:
- It boots and shows the Oneplus logo then screen all black. I know it booted cuz the touch buttons work and i can ear the sound of unlocking etc. Also if i plug into the pc I can easily access its memory.
- If I try to enter recovery I know it enters too but the screen is all black, the only mode I can see the screen is fastboot mode and it stays and acts normally.
- I did a full reset on the phone back to stock via adb, thinking it was software, its all stock now, still the same occurs
Im out of ideas so I just think the screen is faulty from ebay, did this happened to anyone?
Thanks in advance
Accidentally laid on my screen for 20 minutes and it started making random inputs and not registering any of my touch inputs. The screen was flickering a bunch so I figured it was hardware related and opened up the phone. Everything was fine internally. The phone turns on, but the screen does not and does not register touch. The notification LED lights up when I plug it into the computer showing that it is charging (shown as a portable device in Device Manager) and the fingerprint sensor registers touch. Sadly it is not in USB debugging mode so it is not seen by ADB or MiFlash.
I am running the January patch of crDROID. Initially flashed an EDL package (Axon7_LOS15.1_180925_B12Oki_TWRP_LABS1.3_FULL_EDL.zip) and then installed crDROID with TWRP. Could it be software related or did my screen just die? I was thinking of trying to factory restore or reflash, but I figured I would see if anyone has any similar experiences first. Sorry for the noob question.
EDIT: Messed around with it again. Unplugged the battery so my alarm would stop going off. Plugged it back in and now the display works but doesn't recognize touch. If I drag down from the top, I can get the notification bar to come down about a quarter of an inch, but that's the extent of touch it recognizes. I think I'm gonna try and dirty flash at some point using a mouse to navigate the screen, but it's looking like I must have just damaged the digitizer. Anyone have any idea?
