Camera not found occasionally connected - Nexus 4 Q&A, Help & Troubleshooting

Hi my nexus 4 has this problem, the camera does not connect but sometimes connects and works for a few minutes or only once when used.
Normal it worked before but switch to CM13 and install some device drivers soon I started to give this issue
Return to the ROM Chroma and was the same with any camera
I returned to the stock 5.1.1 but still the same
¿Could you help me?

I would suggest see what happens after you run your device in the safe mode. If your camera works well in the safe mode then your drivers/apps are at a fault and all it needs is a factory restore. If not, something is definitely wrong with it. Steps to access the safe mod:
Press & hold the Power button.
In the box that opens, touch & hold Power off.
You'll see a “Reboot to safe mode” box. Tap OK.
Your device will start in safe mode. You'll see the words "Safe mode" in a box at the bottom.

Thank you for responding , to enter safe mode first thing I tried was the flash down the notification bar.
After 5 seconds set on the flash signifca what the camera is connected after that switch it off and turned to light
Not returned to turn more , even when the flash icon was on, some help?

How to get into Download Mode

Samsung Vibrant Download Mode
Method 1 (without ADB):
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen (screen turns on when plugged in) EX: Shows a battery, shows error messages if bricked, etc. Shows anything.
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold both the volume up and volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!
This is how I got into download mode to fix my 'odd' brick.
Method 2 (with ADB):
1. Turn your phone on
2. Go to Settings -> Application Settings
3. Enable Debug Mode
4. Plug your phone into your PC
5. Install Android SDK
6. Open Command Prompt
7. Type: cd C:\android-sdk-windows\tools
8. Type: adb reboot download
Either of these methods *should* get you into Download mode. After that you should be able to use Odin to revert to stock, tar and instructions here:
http://forum.xda-developers.com/showthread.php?t=734475
Or flash anything with Odin.
I am in a situation where I rooted my phone but never made a recovery and now I did a factory reset and I only get a force close loop when booting and cannot do anything. I am not able to get into debugging mode to use ADB and the hardware buttons are not working any suggestions on how I can fix this
The only thing i did was remove some bloatware which is why I did not do a recovery since I wasnt removing anything important. Phone worked fine until I tried to do the factory reset now everything just force closes and cannot do anything
I turned my phone on then removed battey. hold vol up and down together then plug the phone in via usb to pc, should enter download mode after a few seconds (don't press the power button at all)I use odin to flash back to stock.
THANKS!
This saved my ass lol I was lookin at it like wtf? cuz odin failed and then when i reloaded and tried again nothing happened so i unplugged. I don't know what I was thinking when I did it, but I did lol.
Thanks again bro

just Odin back to stock and start over there is realy no other way to fix fc
OP: what youre doing in your hardware button combinajtion method is lettinf it boot, then pressing the up+down vol and doing a hardware reset (by holding power key). You can cut oout a step by holding tthe up down keys when you plug in. It should boot to download automatically.
Also, you should mention in your post that the button combination is different for people who flashed gingerbread bootloaders..
Another thing, i believe the newer android sdk moved the adb package to C:/android-sdk/platform-tools/ ..
To tthe person with the force close issue, read the OP, go into download mode and use odin to flash to stock.

Apparently I forgot to add the line to put it back in, Wow D: Atleast theres clarification ,Thanks for that. Will add it
@tanmay, Dark grey? That means the phone isnt completely powered off, Theres still backlight, Has to be completely powered down, I do hope its done in download mode. Anything flash related is purely in download mode to assure 100% safeness
but it doest help(((.it seems it is turning on but no download mode image.is it normal?
we know that we have to put it back....but the screen lightens up to dark grey and no download mode.what to do?

i think that he's saying that the phone isn't going in download mode after putting back the battery......but if he didn't put the battery back in then he just had a blond moment
Check and see if you can enter recovery mode or if its broken. Vol Up + Home , Then 1 sec gap, Hold power till it vibrates, Make sure theres no backlight or thats not completely shut down.
@rit, Well yeah :\ Cause you know, Phone without a battery and hoping it will turn on--Just no comment there rofl
could you go into download mode?my screen is still lightened gray

did you wait for the latona process to pass completely?
may i unplug the usb cabel?i am absolutely noob
same here...my phone goes completely off...then i press the three buttons as mentioned for download mode...then the screen backlit(dark grey) appears and i lay here frightened and unhappy!!
and is it possible to cancel the flashing process and return back?if yes writ me how please

yup..it was totally over...i earlier flashed into xxkb3..it was no problem then...dunno what happened now...SAD
plus i have my usb cable removed
Mines works perfectly o.o Flashed mine before making the guide. Hence the guide.
1. Take out the battery. 10 secs just to be safe. There should be no light. Or phones still alive.
2. Yes the 3 button combo is annoying, But its the only options android has given us. Recovery mode can break but it can be restored. Download mode is your highest prior. I dont know if your battery is low. If it is then use a direct power supply, phone will turn on without a battery. See how far it gets to turning on.
3. Replace the battery and retry the same, the pit file shouldnt harm the phone in any way.
4. See if you can enter Download mode.
Also i hope you flashed it when it was in download mode. The android digging picture should have been there when you flashed the pit or any other file. If you flashed it on a black screen *happens when adb server keeps the com port alive* it bricks the phone.
if there appeared pass on the odin, it means yes.yeah?

yes you can remove the usb............may i suggest taking off the battery for a while.........go for a walk , catch your breath and come back maybe it will work then!
Yeah, That means it worked. The pit file is just to prepare the phone.
See if this helps you in anyway

i removed the usb cabel. then tried to go in download mode.i am in download mode now,the image appeared and now connect ub again and continue the process?

[Q] i9505 s4 button problems

hi, I have just registered and looking for some help if at all possible,
I have a galaxy i9505 S4 and recently the Home button seems to come and go, and the power button the same, and also the screen keeps lighting up every minute for about 10 secs, if i remove the battery I can restart the phone, and also the home button works to start the phone in factory reset mode, so i feel it might be a software problem rather than hardware.
is there any way to get the phone to reinstall the firmware, as factory reset didnt help
the phone is on orange (EE) UK
thanks for any advice or help given.

hi, thanks for the reply,
the home button just dont work, single click, and holding it in for the task manager dont do nothing either, but if i turn off the phone and hold the home, vol up, and power button, it boots into reset menu fine.
on and off the power button dont work, and i have to remove the battery to restart it.
the screen just lights up every minute for about 10 secs as if it has a notification, but there is nothing there, it drains the battery to empty in about 5 hours.
cheers.

If u want to reflash firmware,
First u have to install Samsung kies app on yr PC here:http://forum.xda-developers.com/showthread.php?t=2038555
Then install Odin3 on yr PC here:http://forum.xda-developers.com/showthread.php?t=1728605
Download yr stock 4.2.2 firmware from XDA/Sammobile. (make sure it is in .tar.MD5 format)
After finish downloading yr firmware version, open odin.
In Odin, Make sure that ONLY AutoReboot & F.Reset Time is ticked in Odin options.
Load extracted file (.tar.MD5) as PDA in Odin.
Turn off your phone, press & hold POWER+VOLUME+DOWN buttons until phone boot into Download Mode.
Connect phone to the computer and wait for the drivers to be installed. You will see blue or yellow indicator in left top corner of Odin, with phone connected to port: COM:x
Click START and wait until you see GREEN indicator [PASS], flashing is finished.
Then, it will reboot itself. U can unplug yr USB cable.
That's it.

hi, I have just done upgrade and initialisation from Kies, and it redownloaded and reinstalled the latest software, took ages, and the button is still not working, so i guess it will have to go to the shop.
cheers for all your help, the button only works before the OS has started, as i can get into recovery menu.
thanks again.
mechanical or hardware problem
That seems pretty much a mechanical problem (button broken) or hardware issue (shortcut somewhere? could explain the screen problem...)

the buttoon does work, but only to get the phone into recovery mode at startup, so physically the button works, just not when the phone is powered into the android os.
Im a bit out of ideas.

It's a faulty button mate.
You don't need to use the home button to boot to recovery or download mode on the S4.
You can simply press volume up+power (recovery) or volume down+power (downloadmode) no need for home button at all.
This is why you think it works.

It's very true mate.
YOU DO NOT NEED HOME BUTTON TO BOOT TO RECOVERY, SIMPLE.
Your issue sounds different to the OPs.
If you refer back to his first post, he said his power button doesn't do ANYTHING.
"the home button just dont work, single click, and holding it in for the task manager dont do nothing either, but if i turn off the phone and hold the home, vol up, and power button, it boots into reset menu fine"
Yours works.

[Q] Phone will not boot, nor enter recovery mode HELP!

Was attempting to switch back to stock messaging app, and was using some old rom (mint jelly) with Titanium backup/rooted. I made the following changes :
unfreeze messaging app
restart bluetooth pairings
uninstall beauty face
uninstall best face
and then restarted my phone, and will not come back on? What the hell?
Will not enter recovery, at all. Just stays frozen on SAMSUNG. Not amused, please help if you can
Are you sure you are pressing the correct buttons? Volume UP + Power, when the device vibrates release the Power button and when 'Recovery Booting...' blue text appears release Volume UP button.
If you still can't enter the recovery mode there is only one option left: flash stock firmware with Odin!

however there doesnt look like much i can do with recovery mode. the only backup is a year old and might as well be reflashing. is there some way to get into safe mode and maybe undo the changes i made in TitBackup?
To start Safe Mode you have to Power on the device with the Volume DOWN button pressed, until it boots up

Cannot enter recovery mode

Hi friends,
I have a Samsung galaxy J5 2016 (SM-J510F/DS). It is continuously rebooting, it reaches till android home screen and reboots from there. While in the home screen it shows a msg (Android is Starting.....), and then it reboots. I have observed that all the button presses and touch is working for a short duration in between the reboots. I have searched all over internet and tried numerous ways to enter to recovery mode, download mode, nothing is working. My home button is also not working. Can somebody suggest me a way to enter to recovery mode so that I can do a clean wipe and start new. Please help. Thank you.
Hi,
Did you tried to make reset from within phone settings ? May be you are able to enter Recovery Mode after that!
( My Samsung Galaxy J 3 pro was almost in the same condition rebooting again & again, One Repairer even said that the display has gone but I was able to enter the recovery mode > Bootlaoder > Download Mode & flashed latest stock rom with ODIN > Working perfect now! )
I turned off the phone before it reboots. Once it was completely off, I pressed ''Volume Up + Home + Power'' Buttons all together, released them as soon as anything appeared / flashed on the screen, an installing update screen appeared & then I was right in the Recovery Mode with all the options.
Thanks.
Thank you for the reply, but my home button is not working.
boyuljalok said:
same case as me. theres a third party apps that let you go to recovery mode google "Ultfone Android System Repair" i recommend you to download on their official site, the only problem that this app has is your phone need to be on if its off the app wont detect it

you can try something extreme like shorting home button contacts, but it might be a bit difficult.
