[Oppo Find 7 and 7a] Scratchling:
So my earlier fiddling, yesterday:

1.2.7i → CM12 29/3 → Stuck Boot Animation
1.2.7i → CM12 21/2 → Stuck Boot Animation
1.2.8i → TWRP Root Process → CM12 29/3 → Stuck Boot Animation → CM12 21/2 → Fix Perms → Stuck Boot Animation →Remove Bootanimation zip → New Bootanimation Still Stuck → Wipe Dalvik data cache system → Black Screen → Cm12 29/3 → Bootanimation Stuck
1.2.8i → Wipe Dalvik/Data/Cache/AndroidSecure → CM12 Flash → wipe same set → Stuck Boot Animation → Swap Layout(why not) → Stuck Boot Animation
1.2.8i → Unify → Still Bugged → De-Unify.....Use this as "clean start".

1.2.8i → fastboot.exe boot Gummy....→ Install CM12 29/3 → Factory Reset Wipe → Boot direct to bootloader → swapLayout → Booting.........STUCK → UNIFYbootloader → Stuck....

This is where I stopped taking notes, and f'cked it up further.

Then, to get her back, unbrick method. This is the only thing thats gone smoothly. Unbrick tool is reliable and worked excellently, I'd highly advise everyone who's romming has it ready in case its ever needed. Restores 1.2.5i with all partitions etc as new. Delish.

Regarding unified storage and CM12. Im sure it can be done, but Im also pretty sure Mosfets instructions arent 100% complete. I followed em to the T and still got the mini partition ruining things. Maybe this is something he started with slightly different to me, or 7 vs 7a, or what, I dunno, but for the life of me I cant get unified without that little runt.

1- IMPORTANT! Clean instal ColorOS 1.2.8i (I downgraded from 2.0.7i beta) search for it in the Oppo Forums.
2- Install Gummy-CWM-based-touch-recovery-find7.img in fastboot mode (rename to recovery.img for practicity and flash in fastboot mode in the known manner).
3- Install CyanogenMOD 12 last nigthtly with the Gummy-CWM-based-touch-recovery already installed.
4- I used the Coldbird method -- partitiontool.zip -- to unify storage just run swaplayout.BAT with the phone in fastboot mode (Coldbird tutorial search for it in the third party development forum for Oppo Find 7 in the Oppo forums if you dont know what are you doing ) ---- during this proces I only get a black screen for 5 or 6 minutes, wait for the tool to end the process the phone reboot itself ----.
5- Let run the first boot of CyanogenMOD 12 with unified storage.
6- Install the recovery unify-recovery-2.7.1.0-find7v2.zip just run installrecovery.BAT in fastboot mode. (Same Coldbird tutorial on the Oppo forums If you do not understand what I'm talking).
7- Enter in recovery and install gaaps of your choice clean cache and davlink then reboot and enjoy!
8- DONE!!
9- OPTIONAL flash the lastest TWRP for Oppo Find 7 in fastboot mode.

Then in another thread:

Not included in above? And anyways theres more, as even doing so does not get you a working unified storage without the spare partition.

Anyways, right now I'm on CM12 31/3/15. And having problems.... (rips hair out).

TB restores keep getting stuck

Cellular connection is poor/highly erratic

Icons for apps disappear from homescreen after every reboot

At this point Im heavily tempted to just go back to COS for my own sanity. But I know how good this phone can be with a decent FW setup and non botched partitions. Maybe nameless is where I should be looking...
