Are you using the stock recovery or TWRP?

You need to perform a full wipe (system, data, cache, dalvik cache) in order to go down, which will wipe everything except your internal storage. You can use Titanium Backup to make a backup of your apps and then restore them after you've flashed the cm-12.0-YNG1TAS2I3 zip. Titanium requires root, so if you don't have root you'll need to flash SuperSU in order to use it.

Why do you wanna downgrade good sir? is there some problems?
im still on kitkat 4.4, and since the new update to COS12.1, i've been considering to upgrade, but still trying to consider the pros & cons here

Question 1: before you flashed the rom, what wipe options did you select?
Question 2: can u get into the bootloader?
I wiped cache and dalvik. (and I did factory reset to)
and yes, I can even start CWM, but I can't find my backup

So it's not in a bootloop anymore? I use TWRP not CWM but I wouldn't think that updating versions would change the source destination path of the backup. Sidenote: after I rooted and backedup my G for the first time, the auto generated name (which was that time/date stamp) had a weird date of sometime in the 1970's and I wasn't able to use that backup because it didn't backup the /system data for some reason. I could still see the backup tho, just not use it

Nope, no bootloop, I hold the powerbutton for 5 seconds. But that I can't find my backups is the real problem, I really can't find my backup anywhere (I can use a filemanager in CWM)

I can't say where the backup went but if u freshly unlocked and rooted it before backing up, there can't be that much data lost! You would need to just reflash the stock firmware and backup if that is your intent; to have a stock backup :laugh: and I'm happy it's no longer in a bootloop. I would suggest going forward to save nandroid backups to usb-otg storage device so it can't be wiped from the phone.
I flashed the stock rom with this guide (http://forum.xda-developers.com/showthread.php?t=2542219) but I am still stuck in bootscreen..
So flashing roms doesn't go well.. What now? (thanks for helping!)
And now my phone can't even see my internal storage anymore...

I faced a similar issue and i have found a answer another user gave me after countless "did you wipe this/ DID YOU WIPE THAT? responses"
what i did was i downgraded to JB 4.3 img ad once i flashed that and it booted up and flashed the philz edition cwm and then i was able to insatll a custom rom.
before this i was on stck 4.4.2 and NO custom rom booted past bootlogo until this solution.
btw i donwgraded to 4.3 in fastboot and flashed custom rom in cmw.

When you downgraded to JB did you also wipe the internal SD or did you just flash system and kernel via fastboot?

Ideally you should wipe everything and then clean install the ROM. To retain your data and apps, you can take backup using titanium backup or take backup of data partition using BMM then restore (though I am not too sure about BMM method if it really works perfectly).
If you don't want to wipe then you can try to dirty flash the 6.0 ROM on the existing version. Just don't perform format or wipe, just flash the ROM+Gapps. see If it goes well.

Even if there is OTA support in the ROM then also it doesn't mean that the phone will be updated automatically like how it happens in case of official firmware updates. The OTA in most of the custom ROMs just downloads the ROM file on your phone, thats it. Rest you will have to manually install/flash the ROM using that downloaded file like how you maybe doing it now. OTA just cuts the step of finding and downloading the ROM file from internet. So IMO its not a feature which matters much.
Ok bro...thanks a lot for sharing the info and for the timely response...

Perhaps it's time for you to clean flash? Idk. Sounds like it's bootlooping. 5.9 gapps was 4.4.3. Meanwhile version 6 is 4.4.4. Sometimes its best for you to start afresh to avoid any issue.

No option other than clean install. That type of issue why its always recommended to clean flash the newer versions.
To have little bit of hope, backup the data partition using BMM then later try to restore the data partition using that backup once you successfully flash the ROM. If it works then all is good and if it doesn't then....

What are the steps you are following? Are you flashing using BMM? Which system? What GApps version? Try not to reboot between ROM and GApps flashing. Flash only minimal GApps.
I haven't faced any such issue with any of the ROMs so far. I just follow the BMM guide word to word.
Right now I am having 5.10 build and its pretty much stable and almost bug-free for me on System 1. There are few experiments going on in the builds after 5.10 so I would recommend you should also flash the 5.10 build.

[Q] update with root?

Just wondering if anyone is working on a flashable 5.0.1 update or knows how how to update stock 5.0 (rooted) without a data wipe.
I've unrooted and flashed the stock recovery, but it's saying the binary is wrong when i try to update?
U cant update using air push if ur rooted u can simply flash a 5.0.1 custom rom

If you're flashing system, you may as well directly flash 5.0.1 system

Bootloop

I was trying to get back to CM11 from CM12.1.1. I flashed CM11 33R; the flash was successful but it won't boot into system and was giving some process error. I tried to wipe the dalvik cache but no relieve. So I restored the CM12 backup and it was successful too but the OnePlus One went into bootloop. Please help genius minds!
Running Android 5.1.1
BTW, I forgot to mention, I did it via TWRP recovery and not fastboot.

Yes I did a full wipe. Wiped dalvik,data, cache and system. I've downgraded to CM11 before too but this never happened.
My guess would be that the needed firmware and baseband for cm11 were not flashed correctly.
What is your TWRP version?

The TWRP version is 3.0 0-0
The best idea would be to wipe fully (system, data, cache, dalvik cache) with TWRP, then flash the stock images for CM11S.
