I had Cyanogenmod 11 installed on my S4 and about a week in the front camera stopped working. I went ahead and did a clean install again and the issue persisted. Two days ago I decided to just flash the stock rom back onto the phone and I used odin to flash the stock rom to get it exactly how it came out of the box. The front camera still does not work, and now I discovered the back one works but when I try to turn on HDR it freezes and crashes like the front camera. It says "warning camera failed". I've reset app preferences and took the SD card out but nothing fixed the issue. Any other things I could do to fix this?
Hi everyone.
I have an LG G Flex 2 (H955) that suddenly went on a fritz. It used to be rooted fine, it was on default firmware, 10 something (wouldn't OTA due to rooting), no issues, but as I am a heavy user, enabled multiuser, had a bunch of apps installed and running it started to slow down on occasion, but nothing unexpected. Anyway, few days back, it shut down on its own while I was typing a message and the phone entered bootloop - on it's own. I decided to cut my losses and did the factory reset the hardware way, it booted up, did the "optimizing apps thing", got to welcome screen and - froze - then just restarted. It's been doing that ever since. Sometimes it boots all the way and then freezes and starts, sometimes it gets stuck on LG logo, sometimes even boots and works for a minute or two but still freezes and reboots.
I can access Download mode, and HW factory reset. I flashed several stock ROMs I found with LG flash tool 2014. It goes without a hitch, boots up, again gets to the welcome screen and reboots. I tried to to the dd cmd way to flash the only system.img I found online, but I get a security error at boot. It gets fixed when I flash the stock ROM again with flash tool. I am at my wits end. I have no warranty, I have no backed up original dump. With my limited knowledge I have somewhat of a hunch that one of the partitions might be corrupted as it boots most of the time but as it tries to write or read something from somewhere (hence showing the Welcome screen) it dies.
Would anyone have a suggestion as to what I might try next, or had a similar experience?
Thank you all very much in advance for any help.
Have you tried this tool with the appropriate image?

Hi and thanks for the tip. However, no, I have not tried this method as my device is H955, International version, and I am not keen on messing up the phone worse then it already is.
I will look it up in more detail, but as far as I can see it only pertains to the H950 (ATT version)
Edit: I looked it up in detail, and the developer removed the H955 support as there is a KDZ for it and he claims the .kdz is a much better option - however - .kdz does not work for me. It flashes the rom all right, both in Normal and CSE Flash modes, but the problem persists. Turns on (if I'm lucky), freezes, reboots and so on.
D'oh, didn't see the H955 part. :-|
Sorry to hear you are still stuck, can't offer much more unfortunately.
I know one of the flashing modes does a reset, but maybe a reset after the flash might help.. i think it's, from powred off, down plus power until the lg logo then release and then hold power on its own until you get to a recovery screen where you can reset.
you probably already tried that I'm guessing though. taken memory card out if you're using one?

Hi and thanks for yet another tip. However, you guessed right - I tried everything - reset from the recovery, before the flash, after the flash, in the middle of flash, with memory card, without memory card, tons of times - you name it, I've tried it. And still, it boots up (sometimes, though), freezes and go bye-bye. I'm completely out of ideas. If I could somehow rebuild partitions from Download mode, or use ADB, or push some image I found and flash it directly, but there is no way to push files to phone in Download mode (and 5.1.1. disabled external memory, so that is out of the option too).
It seems I'm stuck for now. I'm wondering if the repair guys have some tricks up their sleeves, perhaps with those hardware boxes, jtag something or other...
im on same boat with h955p, any solution?
the battery is the problem 100%. i had the same problem and i managed to fix it with buying a new battery and replacing it. 10$ on aliexpress plus you get the tools and it is really easy to replace.
hi. i was stuck in this situation. you can reflash the original stock rom back from LG UP software. at me this was the problem. my friend have a korean model and at him the 4g data connection was the problem...i was on the update of the marshmellow and freeze and reboot...factory reset didn't do something cool and keeps rebooting...but i was smart and lucky and my brain was thinking at the reflash of the phone...so i was to the reflash so my phone was completely and fully functional...no freeze , no reboot...and look for the v20a italy firmware (stock rom)...i say this because this v20a italy rom is so f***in stable and no battery drain...better than other stock rom marshmellow. Thanks me later.
Hello I have an issue. I soft bricked my phone and installed a kdz with lg up to fix. Now my phone's rebooting for no reason at no set interval and services stop randomly. Everything else functions well. But I would like to try again I think I used improper kdz file. I have a LG G Stylo T-Mobile but there are 3 options I don't know what one I should use.

I had that same issues. Just go to recovery.(Volume Down+power) The stock recovery will blink for a sec and reboot. After that everything should be back to normal. Which kdz did you flash?
Hi All,
I have rooted my Moto g turbo xt1557 (Just to enable screen casting). After rooting my flash light and camera was not working. I tried to flash with Stock ROM... Camera was working for some time. After couple of hours, rear camera is showing, Please restart your camera error... Flash light is working for 10 sec max... Then automatically it's getting off...
I tried all the basic steps like wipe/clear data/factory reset/camera enable and disable.... No luck.... Even I tried to unroot my phone.. nothing gave a fix..
But my front camera is working like master.... I m sure it's nnot a hardware problem....
Can someone help me to fix this issue.....
Update: Today i have updated the mobile. After that i booted into recovery and wiped the Cache Partition. After that camera was working for some times. Later it came to same state. Camera Error: Please restart the camera...
Can some one help me quickly????
I have a sm-g930a s7 at&T. about 2 weeks ago my camera and flashlight quit working. I have tried the following:
disable smart stay
, reboot phone.
went to camera app, force stopped, cleared cache, cleared data, restarted phone
, restarted in safe mode, camera still not working in safe mode.
cleared system cache, wiped data, did factory setup. camera not working
Changed the software on phone using odin. flashed G930AUCUBCTB1. Odin worked, Camera not working still. I was considering trying a ball peen hammer, but not there quite yet.
My backup phone is a s7 edge with a beautiful pink line.
Any idea where to go from here?
I have the same problem, open camera and I get a black screen followed by a "camera failed" message. Tried different apps. Actually replaced the rear camera. Reset phone back to factory stock. Did all of the "other" stuff. Nothing works. The problem started shortly after the last (February) and final OTA update that ATT did. Anyone have anything I can flash to my phone with ODIN? It is a SM-G930A Baseband G930AUCUBCTB1.

Try installing a different camera app and see if that works. If it doesn't, it could very well be the camera itself.

I have tried 2 or 3 different camera apps. No help. I forgot to say that the camera will actually come on very very occasionally.
