Front camera FW Null after flashing custom ROM & recovery - Android Q&A, Help & Troubleshooting

Hi
I recently flashed my SM-J701F(Samsung Galaxy J7 Nxt) with TWRP for Samsung Galaxy J7(2016 Exynos).
My device stuck in a bootloop after that, and I had to install this custom ROM https://forum.xda-developers.com/ga...rom-nemesis-nougat-port-j7-2016-v1-0-t3655621
Thankfully the ROM is good and most things work as they should, but now the home button isn't functioning, and the camera app is misbehaving
It says "Server error occurred. Restart camera" everytime I click a photo, and the Front camera is simply blank.
When I checked the Camera firmware, it showed "NULL" for the front camera (Front cam fw ver: NULL).
please help

[Q] Samsung Galaxy S II, Camera Not Working and Screen is Black

My Samsung Galaxy SII had been working fine, no issues at all until two days ago I went to take a picture and the camera won’t work, the camera screen is black and hanged up when I press to take a picture for a while then I just keep getting some error messages like force close, and media server not responding. I've tried to clear the cash and data for the camera application but nothing happened, I wiped the cash from the recovery mode without any success. Also I downloaded the app GalaxyS2 Camera Firmware Update and after installed and open the app freeze after the message of turning the phone to the airplane mode then nothing happened.
I tried other apps using camera some of the not working at all, and some recording some videos with the black screen on but after finishing recording it showed me what recorded but even this happened after long time of waiting for the app to do recording.
I tried to do the test for the camera using the code *#0*# for the back and front cam but get the error message of "activity factory test not responding (wait or Close)" then Camera failed. I searched over the web but most of those who had the same problem mentioned that they did factory reset with no luck.
My phone running:
Andriod version 4.0.3
Basedband I9100XXLPX
kernel version of 3.0.15-I9100JPLPF-CL644992

Build number IML74K.JPLPF.
Hopefully I will find a solution

I did a Factory reset from the recovery mode and it works for awhile and the closed with media scanning running error then I unmount the SD Card and now it works perfect, and when I mount it again the error message comes again..
I think the problem from the beginning with the SD card, so for anybody faced this first start with un-monunting the SD card and see what is happened first before he/she loose his/her other apps.

[Q] Strange problem with camera, works partially on fxp not on stock

hi all, i'm experiencing a weird problem with my camera:
on fxp (from 210 to 212) only main camera runs, when i try to switch to secondary it stops and ask if i want to kill the app, if i say yes and restart camera it says "unable to connect to camera" untill i reboot my xperia U
after that i tried with stock sony fws: the stock camera app never runs, while others (eg: pudding camera, camera fx) runs, but only with main camera...
i have also relocked bl in order to test again stock fw but without results...
any idea?

(Can't connect to camera) S3 i9301 with CM12

Some days ago I installed a Resurrection Remix Rom (I actually don't know which one, sorry. I just know that it's got Lollipop) and when i went to the camera it said: <<Can't connect to camera>>
I still had warranty, so I installed the stock rom (I checked the camera and it still didn't work) and I sent the phone to the company. IMPORTANT NOTE: In the warranty ticket it said <<SOFTWARE ERROR>>
The only camera I can use is the "selfies" one
When I received it, the error was fixed, so I tried to install another ROM, so I installed CM12. But... I got the error AGAIN and I haven't got warranty anymore
That's what I tried
-Install Reset Camera and Camera (CMFix) (Camera CMFix didn't open and I had Restart Camera Installed :v)
-Checking if an app is having troubles with the camera
-Rebooting in safe mode
-Holding down the volume/power/back
-Clearing Data and Cache of the camera
-Removing my SD card
-Renaming the DCIM folder
- youtube. com/ watch?v=Fa9qggQJ990 (I can't even access to that menu ._.)
-Find “Use NuPlayer” and uncheck it & restart
-Using other camera apps
-Disabling the Google Camera and using the default one
-EDIT: I installed the Stock Rom with odin and did a factory reset. I even did a "system reset" with odin. AND IT STILL DIDN'T WORK OMFG. Then I tried to update the camera firmware (youtube. com/ watch?v=Fa9qggQJ990) because I've got KK now, but the "Phone/CAM FW Ver Check" is disabled. I googled my camera Cam FW Ver and it's not old
Thank you, I'ts a really annoying error. My S3 is giving me too many troubles, I'm starting to hate it... But I can't buy a new one :crying:
OHMYGOD I CAN'T FIND A WAY TO FIX THAT ERROR HELP PLEASE
//reposting because nobody answered :v
LOGCAT:
shri b. com/S3fzYuWo9IrOo9K?v=nc That's the logcat of the KitKat Camera

If you're confident that its not a software issue, then go ahead and unroot your phone and show it once (sometimes the problem maybe that the camera slot just got loose). But 'can't connect to camera' is common from cm12 onwards. Maybe its a kernel problem. The fact that stock firmware also failed is something abnormal. Even in a few Touchwiz roms, kernel changes led to cameras not working.
Anyway, If you're still on stock rom do to the dialer and enter
*#7353# quick test
*#*#4636#*#* for test and information
*#34971539# for Camera Firmware Update and
*#7412365# Camera Firmware Menu

I did *#7353# and tested the camera and it told me Can't connect to camera again, I can't choose "Phone to CAM FW Write (Main)" in *#34971539# and *#7412365# and *#*#4636#*#* didn't work
I guess It's a kernel problem
Thank you so much!
