Full wipe is
- Wipe cache
- Wipe Dalvik cache
- Wipe User data/factory reset
- And manually format /system
If you do all these wipe you should not get any FC on any working custom rom. What recovery version you use?

6.0.3.1

First thing to try is reverse back to your last working recovery

How to do that?

Er.. maybe I get you wrong. You don't upgrade cwm recovery to new version, right? All you do is install new ROM and restore cwm back over it. Is this correct?
CWM recovery backup is not compatible across custom rom. I can restore CM 10.1 cwm back on CM 10.2 rom. But I got FC when try to restore data from CM 10.1 on AKOP rom. If you want to restore /data from difference rom, it's safer to use Titanium backup.

I use jellycream rom now.when i back to stock,i root and get unlock bl,after 2-3 days my phone got fc very often.

You got FC on what application? Clean install should not have that problem. If you post logcat maybe others can help you find out what the problem.

Ok bro,never mind,thanx for helping me.

Need HTC One Stock Recovery!

Hi. I really need the stock recovery.img for HTC One (AT&T) So I can OTA update. I lost my backups of the stock recovery, and need it. Anyone got it?
You need to factory reset and wipe data to do so

I had the same problem once. I backed up the original rom fine using CWM but when trying to restore it, it failed.
I then had to flash Stock rom to get the phone working.
From this reason I have flashed TWRP, although I always preferred CWM
Backup on TWRP is working good ?

Camera failed. Error....(Solved)

Ok so I've flash a couple of Roms in the past dew weeks...but now ..anything other than stock works with the camera.
As soon as I clean flash a new room and open the camera it says "camera failed"
I've tried clearing cache, wiping app data. .. Clean installs. Dirty installs...All kinds of installs lol. Wth!.
Any ideas?
Solved! Thanks to @Soooperstar for suggesting the fix initially.
***Solution***: flash the stock TW Kernel or any other TW based kernel from the threads and it should work.

I JUST STARTED HAVING SAME ISSUE GLAD YOU POSTED YOUR FIX :good:
Mine does this intermittently too. Just go into app manager and clear the data for the camera app and it starts working again. I haven't figured out what's going yet but this fixes it. When you flashed the kernal did you also wipe cache and dalvik?
If so that's probably what actually fixed it for you...
Nope. I didn't wipe. It has not happened at all after the kernel flashed and I fixed permissions.

If you are running MJ4 this will work for you.
Download the kernel attached at the link. https://www.dropbox.com/s/6q9vdr16qjw7g1c/SM-N900P_Stock_MJ4_Kernel.zip
Move the file to your SD or ext SD.
Boot into recovery
Select install
Find the kernel and swipe right to flash.
Reboot.

I recommend you to use TWRP recovery,because it has more options.
If you have root access on your phone you could use app called Flashify from Playstore.
When you download Flashify,put TWRP image on you sdcard and open and click on flash Recovery image option in Flashify.When you click that find twrp image on your sd card and select it.
Thats it.
Link for TWRP,click here.
I tried one app like that and i ended up with system wipe.

This means you did not have unlocked boot loader. Without boot loader unlock you can't install custom recovery or custom ROM. There is a recovery for locked boot loader but it only allowed to install Roms based off of your stock ROM. For anything else you need to unlock your boot loader first
