Cameras not working anymore :( - General Questions and Answers

Hi there!
I'm fixing my friend's Oukitel K6000.
I replaced the screen, power & vol flex cable and when I switched the phone on, it doesn't recognize the cameras anymore (don't know whether it did before the screen was cracked).
Tried everything: all tricks which can be found with Google search, replaced the main camera, made the factory reset, reflashed the ROM. Still there's no camera app available (they've also disappeared from settings). When I'll make tests @ the boot section, everything else works except the cameras. It gives an error "adckIFInit Fail"
Is there anything else to be done? Is the main board damaged and time to buy a new one?
I'd be very grateful if someone could help me with this issue. Thanks in advance!

Wierd Screen Issue

Hi,
I've flashed my phone (HTC Touch Pro) with Hardspl and then the latest Energy ROM.
Everything went perfectly and I was impressesd with how simple and easy it was and how much difference the ROM made to the phone.
Today, while using the camera, the screen went blank.
I tryed turning the phone off, pulling battery and a hard reset but its still the same.
Even after hard reset, the screen is blank but if i press the power button, on the second press, I get a flash of whats on the screen and then it goes blank again.
Should I try to reflash the phone again?
I've searched but not found the same issue
Thanks
The touch screen is still working and sometimes i can see the display, but its very dark and hard to read. Is the flex cable that needs changing?
Why would it stop working so suddenly?
Should i take it apart to reseat it?
Ok, I've found the same issue in a few other peoples phones but they seem to have beeen resolved by sendin the phone back under warantee.
I dont have that option unfortunatly so need to find a fix.
The only thing wrong with the phone is the screen backlight that suddenly failed
Can anyone help me or point me in the right direction please? I cant find a definite diagnosis anywhere
New Flex cable?
New Screen?
Pray?
Thanks
Back to stock SPL and stock ROM
Still no luck

[Q] Touchscreen stopped working on Nexus S

Hi all
Today I was trying to get my nexus s onto the official ota ICS update by flashing it manually, following guides other people had had success with.
I was on the cm9 ics beta, so I had to flash the full rom of 2.3.6.
This worked completely, however I think the ota update file I downloaded was corrupted, as flashing didn't work, it said something about signature verification failed. So I redownloaded it, from the same link, and the new one was bigger. I tried that, and the same error. I tried wiping data/factory reset etc, and I accidentally started to flash a cm7 rom I had on my phone.
I stupidly did a battery pull as it started to flash (the back cover was off already), and now my touchscreen doesn't work. I was able to successfully flash other roms including the 2.3.6 I downloaded, and I couldn't do the first setup procedure (touch the android to begin). I tried cleaning the screen very carefully with 90% isopropyl alcohol, the same stuff I use to replace thermal paste on cpus.
It still doesn't work. I am hoping it is a software issue that can be fixed otherwise I have to return it.
Someone please help
I have used the search function and none of the solutions I found worked.
(UPDATE) I rebooted again, and when the phone booted into cm7, the "internet" icon(the globe picture) on the bottom left of the dock was in the "pressed" state(orange). It was like the phone thought I was holding my finger on it, which suggested a hardware issue. I cleaned it again and nothing changed. Then I held the phone in the landscape position. When the screen rotated, the button stayed pressed. So the phone doesn't think "this part of the screen is being pressed" it thinks "this internet icon" is being pressed. Rotating the phone again and again didn't change anything, the icon was still pressed in.
Defiantly a software issue. I would try to unroot and reroot. Then if it is still not working, try to format the SD card. You may want to considering buying a USB to micro USB adapter to help you, considering then u could plug in a mouse. I have one just in case I need it.
Thank me if any of this helped
Also try and keep this updated with new info. If I can't help, maybe someone else can.
Sent from my XT862 using XDA App
Thanks techno-update, I will try that. I haven't "unrooted" before, Is that just typing fastboot oem lock or whatever it is instead of fastboot oem unlock?
Also, I found a youtube video with the EXACT same problem.
v=zpfE15Xw_os&feature=related
Skip to 3:15, and you will see when he opens the power menu, the phone thinks he is pressing on one of the options, but he isn't.
I will let you know how unrooting and rerooting goes.
Thanks
(UPDATE)
I tried unrooting and then rooting again. It still does the same thing.
Even in cwr I can't use the capacitive buttons to navigate menus, does that rule out software problems? I am really hoping its just a software problem :/
I need my phone for an outing tonight (im in australia, its 5pm now) and I would appreciate it if some genius could solve this
I am usually the "go to fix it IT guy" in my area, but I can't figure this one out. I have tried formatting the phone, reflashing the mod etc.
Is there some more aggressive COMPLETE wipe or something that fully wipes the phone?
UPDATE 2
Guys please help,
I just flashed zulugen mod, as it has the trinity kernel, I don't know much about android os, but I hoped that that might replace the touchscreen driver or something. The rom flashed correctly, but touchscreen and the capacitive buttons still don't work. Please help
Guys, is there some sort of system partition where the touchscreen drivers are kept or something? And when I pulled the battery as it was flashing cm7, it corrupted these?
Is there some way to fix this?
bump
bump. I need help with this urgently. Is it possible the connections for the screen came loose inside? I would crack it open but don't have screwdrivers for the 3 smaller screws on the last layer of plastic before the pc board.

Help - Screen stays black even after reset!

Today I noticed I couldn't hear incoming calls, but they could hear me.
I have cyanogenmod 9 alpha 3 release, and tried reformatting, and reinstalling alpha 5 to no avail. Even called tmo to check if it was a network issue with no luck. Then I noticed my screen go shut off upon opening the keyboard. It would go on and off as if the connection was loose. Now it is permanently off so I followed the directions to factory reset through hardware buttons and am pretty sure it did reset. However, this will just keep me stuck at the recovery mod screen as I know from previous wipes.
My questions are the following:
Is my phone gg'd?
If I hook up a tv out cable to the audio jack, will I be able to see the screen on a tv for reformating to stock rom for tmo replacement?
If I send in my phone with a dead screen, will they know I installed a custom rom and tell me this was my fault?
That's about it.
Thanks.

Display replaced ---> now every 9 seconds it goes black

Hello my friends,
long story short, I totally destroyed my screen, so I ordered a new one from ebay, for my XT1032, replacement went without problems, everything works perfectly but screen turns black for 0.4 second every 9 seconds (aproximatelly) - do you have any experiences with this behaviour? Or any suggestions where is the problem?
Aditional information:
1. as I said, phone version is XT1032 and the new display too (I have not found any difference between old and new one)
2. I checked contacts 3 times, I think, everything should be well connected
3. touchscreen, cameras, battery, speaker, sensors are working as they should
4. I tried to factory reset, didnt help
5. I have old Cyanogenod 6.0.1., so I have made some customisation
6. My last guess is that as I made different customisations to the software side of my phone, maybe the new screen isnt set up for something like that, and I need to do the same customisation from scratch, with the new display.
EDIT 1:
Display in Bootloader and Recovery is working without turning black
I tried to factory reset and flash a different ROM, but didnt work and display still turns black
(I wanted to destroy it because new Moto G gen5 came out , I tried hard to destroy it, but everything is working perfectly, just screen was unusable, so I said: Hell yeah, this phone is godlike, I will keep it )
Thanks for any suggestion.
So old screen doesnt do this strange black screen, so definitelly it is an issue of the new one. My last guess was that something can be wrong with the proximity sensor, but it turns out that probably it is not the problem. I will try to return the display. I have enough and I end this.

Black screen except for camera? J7 Crown. no USB debugging. Recovery mode access

Situation: Samsung Galaxy J7 Crown. Never messed with. USB Debugging not enabled No special permissions (no ADB). I am able to access the Android Recovery screen. Obviously wipe cache partition didn't help, nor Lacking storage booting. Other than the Recovery and download screen: I get the Power/Restart icons when booted normally. Reset works, but power doesn't turn the phone off. No phone calls, Yes notifications. Camera from lock screen comes on (triple click on home button) and touch screen works.
I've tried to trace out the lock pattern in the hopes its still working outside this specific situation. No indication that it is.
All i want is a few sentimental pictures. Although after an entire day of frustration, finding out that the only thing that works is the camera is kinda funny and ironic.
Ive looked on XDA forums, but I'm having no luck w/ exact situation, although I'm sure someone has been in the same situation or similar enough.
Spent all day looking at options (Odin?) and nothing looks like it would work out for me.
Knowing the camera works, makes me hopeful that a mirror would work? No reaction to lock screen pattern makes me think not.
Additional (maybe irrelevant) info. Shows up on home WiFi while Find My Mobile said it was offline (makes sense with Notifications/no calls)
Any advice? Just point me in the right direction if there is one.
If not i hope you appreciate the Irony here. Thanks
(I used to be not so bad tech support, but haven't been keeping up as of late, and today was a painful reminder. Take pity on me.)
Black Screen Except Camera - Galaxy J7 Crown
Hey there anick22! I was so glad to see a search result with something referencing the camera working, on an otherwise completely black screen! I was super bummed to see that noone had replied to your plea for help with this insane problem!! I hope you found a solution by now!!
My 2 month old Galaxy J7 Crown suddenly went black on me one day, and it didn't happen as a result of a drop, or spill, or any other damage. I don't recall having put any new or different apps on it, recently, either.
The triple click of the Home button does open the camera, and the screen lights right up, perfectly. It takes it's usual beautiful pics, and I'm able to use all of the camera functions. I'm even able to view any photos I took during that particular session, buy not any prior pics, because I'm unable to unlock the phone.
"Hey Google!!" also reacts, and will display the result of any question that I may ask it, but I'm unable to go into the answers, without the ability to unlock my phone.
I have been able to get the phone into safe mode, while attempting to power it off, by pressing the power button, and then tapping on "power off" (although this hasn't worked every time I've tried). While in safe mode, "safe mode" is displayed in the bottom left hand corner, but nothing else appears on the screen.
Upon powering up the phone, all of the normal things happen. It shows "Samsung" and goes on to the blue screen to show the "Trac Fone" logo, but once the phone is booted up, the screen is black!!
PLEASE tell me that you were able to find a solution to this!!! I went and purchased a new Moto G7, (since I had a Droid Turbo 2 in the past, and it was amazing!!), and I'm beyond ready to get back to my J7 Crown!! PLEASE HELP!!
Thanks so much!!!
By the way, I'm a newbie here, as If you couldn't tell!!
