Hi!
How can I downgrade my phone to CM12?
I flashed the bootloader and Radio, flashed the last nightly and gapps and wipe dalvik/cache but I get 'Android.process.media has stopped'.
Must I do a full wipe to downgrade?
Thanks in advance.
I would also wipe data (not a full wipe) because there were many changes from 12 to 12.1.

Thanks Daniel. I will wipe data and system partitions.
There is a lot of difference from CM 12 and CM 12.1?

Finally, don't work the wipe for me. I had to recover an old nandroid of cm11 and update it to cm12.
Now I have an stable cm 12 nightly build... but it wasn't easy

Hi !
I have installed on my xoom wifi MZ604 Team EOS ICS ROM.
How to update the ROM?
I mean: How to update the nightly build?
My is Eos-wingray-47 build and i want to update to 48.
I need to flash it as a normal ROM?
And what about the G-APPS? Just flashing it?
no need to wipe? thanks
Wipe the cache and Dalvik Cache. Flash the new nightly build and then flas the Gapps. Do not reboot between flashing the nightly and Gapps.
That's how I have done it for every build since they got the camera working and not had a problem.
So I have to wipe?
No you don't need to wipe data, just the cache and Dalvik Cache (it's recommended that you do this to make sure old cache information won't cause issue with updated info).
OK...
And when flashing the G-APPS i dont need to wipe,right?
just cache?

No need to wipe anything when updating Gapps if you flash Gapps immediately after you flash the Eos Nightly.
It depends if you are changing versions of Gapps. If you are just reflashing Gapps after flashing each nightly then no. If you are flashing a different version of Gapps it depends. You need to look at the release notes for that version. If you were running version 9.x and upgrading to a 10.x version a full wipe was needed. Incremental 10.x upgrades, say from 10.1 to 10.2, did not need a full wipe.
The biggest thing that I have seen cause problems is that people are rebooting between flashing the nightly and Gapps. This is what I recommend.
-reboot into recovery
-perform a backup
-wipe the caches
-flash the new nightly
-flash Gapps
-reboot
I always perform the backup. Yes it takes some time, but when something goes wrong you always have the ability to revert back to a good working state. Well worth the few minutes it takes to have that peace of mind.
If I would like to update to latest nightly of CM12.1 do I have clean wipe or simply flash the latest zip?

i can only answer this surely if you tell us which rom/ version you currently using .... but if you allready on CM12.1 update this way:
(dirty install):
backup current rom (in case of problems)
in recovery install the new update
wipe cache + dalvic-cache
now, if you get any issues or FC's etc... you will need a clean install (fatcory reset / data wipe)
remeber this rom is still under development so sometimes a clean install in fact is needed...
I'm trying to flash the latest /bacon nightly zip file on top of the stable cm12.1 with TWRP 2.8.6.0 and I'm getting an error that said cannot install this and advice me to do a factory reset instead. What do I do wrong?

What exactly are you trying to flash over the top of? When you say stable do you mean the stock ROM (Cyanogen OS 12.1)? If so, you can't do that, they're different ROMs. When going from the stock ROM to a nightly (or vice versa) you need to wipe properly (system, data, cache, dalvik cache) first.

Thanks for the answer, this I was after.
I installed CM 13.0 Nightlies since the 12.1 Nightlies stopped so and it seemed great at first, Doze, Now on Tap, etc. But ever since i have been running CM13 nightlies there have been too many problems, for now, and random reboots. Is there any way to downgrade back to CM12.1 snapshot(preferable b/c more stable) or nightlies without loosing all my data? Thanks in advance.

First, perform a backup of your existing setup, and then perform a clean install (wipe /data and /system; TWRP is recommended). Next, try flashing the ROM and see if it installs; if it installs without any issues then congratulations! Now just flash a Google Apps package, and then reboot.
Only your internal storage will be safe! But it is recommended to backup atleast once if in case anything goes wrong.
+1. Follow the above procedure and that should do it. Why do you want to downgrade ? cm13 is pretty stable as it is.

He probably did not read why these reboots occur and when they started.
Being up2date with the current development is mandatory when using a custom rom...
Very confused.
At CM site latest stable is showing this:
cm-13.0-20160819-SNAPSHOT-ZNH5YAO0IN-bacon.zip (366.21 MB)

The first one is CyanogenMod without gapps & less features than the second one with is inclued Cygn next camera & galery , live lockscreen , gapps , cortana , microsoft hyperlase and munch more but isn't updated daily or weekly like CM13 only one update per month so choose your camp
CM13.0 is the community version and COS13.1 is the commercial version by cyanogen. You can also get images from the official website https://cyngn.com/support

I am using CM14.1 and it's definitely better than CM 13 or COS 13 (also they are not being updated now). It is updated regularly. As of now it has not all the features of CM13 as it is still in early development stages. Also, it may contain bugs but it is definitely a daily driver material for me.

thanks, so CM14.1 nightly is definitely an upgrade for CM13, right?
will I need to re-install everything after flashing 14.1 over CM13? will I get OTA for new built after or have to do it manually and re-install everything again?
I think I have TWRP, what is the correct way to go from CM13 to 14.1 nightly? sorry, am a newbie on flashing and afraid to brick the phone,
thanks again,

Yes you will get OTA almost everyday since it's nightly. And no you don't have to re-install anything again with every update.
For Flashing CM 14.1 you must clean install. In the process you loose all your data including internal storage, apps, call logs, messages, everything.
Go to TWRP recovery > Wipe > Advanced Wipe > Select Dalvik/ART cache, system, data, cache > Swipe to Wipe
Then you can flash CM 14.1 zip and gapps.

lastly, battery life is most important to me, CM14.1 or resurrection remix? thanks again

While flashing you'll see 2 lines of 'Unknown log' or somethong like that in Red color, just ignore that.
Use 7.1 nano gapps.
Battery life is not that great but yeat it's decent. Although standby time is good. I don't know about ressurection remix since i haven't used it. But it is based on CM14.1 only so i assume it os goos too.
