[Q] Downgrade from CM11 to CM10.2

ioannis_m said:

I've tried to downgrade my Galaxy S in order to take some backup from the nandroid that I kept (msgs,call log etc) to sms backup and then to upgrade again to 4.4.

I first flashed through .zip 3.3.0.s semaphore kernel (my last 10.2 snapshot was patched) in order to flash snapshotM1 = jb gapps.The kernel was flashed with no problem but when i tried to flash the rom it got aborted (red triangle).

What further must I do to downgrade to 10.2?

Thanks in advance.

I've read from other users that in order to restore an 4.3 (10.2 in our case) nandroid i first have to put a 4.3 kernel on the phone (after factory reset/wipes etc) .When i do that the kernel goes like a butter into the system and when i try to flash the nandroid i'm getting an aborted sign with the red triangle .(my phone says to me no nono no no )

So if i want to go back i simply load the nandroid without the kernel?

I just flashed the previous nandroid (10.2) with total success and no errors.Just flashed it from kit kat to Jellybean without any kind of kernel flashing.
I guess it was wrong to flash previous kernel after all.

Flash CM10.2 from recovery (workaround: restore a 10.2 backup or flash a 10.2 kernel before flashing) ==> so this should work ...have you tested that?
