Hi

If you've done a nandroid backup, flash it.
If no backup, you can safely flash with odin a 4.2 ROM from sammobile.

Done the both because of some problems with kitkat and worked fine even if I'm on kitkat now with everything working fine.

I was wondering the same thing myself cause i tried several times with different Stock ROM's without any success??

When you are trid to flash it comes up with some kind off authenication error (The only ROM i able to flash is the 4.4.)
And i am not even able to Root without getting stuck during boot. Tried several senarios.
CF-Root causes boot lock
T
ried Also : recovery_6.0.4.7.tar.md5
Then i get this Warning: kernel is not seandroid enforcing

Status for SE for Android:
Enforcing + type details

Build no:
KOT49H.I9295XXUCNE4

I read somewhere that a Stock ROM with modified files could do the trick:
http://forum.xda-developers.com/show....php?t=2715435

Maybe such a ROM would do the trick? Maybe someone else has done this work already.

i hope so - cause It kinda sucks running a Stock ROM

revert to 4.2.2
hello,
i have a GT-I9295
i have updated from 4.2.2 to 4.4.2 PDA: I9295XXUCNH2 released 7 aug. via odin 3.09
had to do a factory reset to get wifi working, etc..
i then wanted to revert back to 4.2, but i couldn't, and still can't... i did the following:

- flash with odin the 4.2 from sammobile: error: NAND Write Start!!.....<ID:0/004> Complete(Write) operation failed. soft brik, Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again.
- tried to reflash the 4.4 firmware i already had with odin...same error.
- couldnt boot the phone again untill i flashed cwm 6.0.5.0
- installed carbon rom from cwm no problem. did reset, wipe cahe, format system, etc. i now have the not seandroid enforcing message when booting and entering recovery, but everything works.
- tried to flash again with odin the 4.2 official, still no luck. same error right after nand write.

i remember downgrading from 4.4 PDA: I9295XXUCNE4 to 4.2 PDA: I9295XXUBML3 with no problems a while back on my other i9295 via odin.
is the bootloader different in this version of 4.4 i flashed than the one i flashed a while back?
the weird thing is that i get the same write failure with reflashing 4.4 with odin.

any thoughts?
thank you
