Camera failed warning on 4.4.2

Hi I hope you can help me with this,

I was on a custom 4.3 rom running on old bootloader. I then
updated to 4.4.2 rom but my camera is not working only a black screen and giving
me a warning message " Camera failed" and once that happens
the whole system lags. I've read around that it could be a hardware
problem but when I switched back to the 4.3 rom the camera is working
smoothly again. I have tried 3 different 4.4.2 custom roms but same issue persists.


My question is could this have anything to do with my bootloader? I am planning
on flashing a stock 4.4.2 firmware with the new bootloader to see if that helps but what
worries me is if this doesn't help then I have no way anymore to go back to
a 4.3 firmware where my camera still works. Can you help me point to a solution
to this problem? Or which stock firmware I should flash to test if my camera
will work on that firmware.

Did you fully wipe before flashing?

What custom rom did you flash? Do you use the correct modem for the old bootloader?

I have tried Phoenix ROM, GoldenEYE , ECHO ROM, I am not sure if
I am using the right modem though I just flashed the file suggested on this page.

I'm on the Phoenix rom and it's running stable for me. I am also running on the old bootloader.

I had troubles at first after upgrading to 4.4.2, but after I wiped /system in recovery, everything worked.

You could try it. Make sure to backup /efs to your external sd or pc. Backup your entire internal sdcard, because it will be wiped. I didn't know that, so I lost everything on my sd :P

Perform a full wipe. Then wipe /system from the recovery (i used clockwork recovery). After that just flash and don't install any tweaks in aroma.
