The following I posted in the old CM11 thread as I did not know this one existed. How come one of you did not mention it in that thread? So for those of you not visiting that thread, here is what I posted.

Well, I finally broke down and installed Sullin's CM12.1. Here are the basics of what I did. I used Philz_CWM-jcs-dm-tenderloin-20140317 to install the 12/26 Rom and the gapps-511-base-20151205-1-signed.zip. I had Sullin's 11/16 CM11 Rom installed previously. Now Philz CWM has a really neat feature under "Wipe Data/Factory Reset" labeled "Clean to Install a New ROM". This allows you to jump around between Roms like AOKP, CM and Evervolv without having to totally wipe out everything and start over like before. I don't think TWRP even has this feature. Needless to say, I now have CM12.1 and Gapps installed and so far, everything I have tried works. I don't know if anyone else knows about or has tried the following. I had made a Nandroid backup of my CM11 install. I used Philz CWM and did a restore of just the data part of the backup. Everything, data, apps, settings, all home screens restored perfectly with the exception of a couple of app icons. I just had to drag them back from the app drawer to fix that. This is not the first time I have installed a Rom cleanly and used this method to recover all my stuff.

So far, Wifi, camera, and sound all work flawlessly. I've played Netflix and YouTube videos with no glitches, hiccups or hesitation. I have not tried Blue Tooth yet, but others have confirmed it works. I've had no BSD's or random Reboots. Since the performance tab is missing, I used CPU Control from Rom Toolbox Lite to up the CPU to 1782MHz. The default speed when I checked it with RTL was 384/1512MHz. I/O scheduler is set at bfq and Governor to interactive. The only thing I have noticed is occasionally, there is a small lag either when starting an app or closing one. After giving the tablet a few hours to settle down, sleep battery drain is running -6/-7mA, just like CM11 was.

I can say I was not sure that using CWM to install CM12.1 would work. But the fact that I already had a data media Rom installed and I had used TPTB to increase the /system to one gig, I was not afraid to give it a shot. Philz CWM-DM does all the work for you. Unless something unforeseen crops up. I see no reason to go back to CM11. CM12.1 does everything I need it to do and it does it well. Last but not least, I reran Antutu Benchmark and it clocked in a 20,000. That's a nice jump from my CM11 score I posted previously.

Not bad.

Below is part of a reply I posted that may help you uunderstand using CWM to install CM12.1 without using TPTB:

Yeah, I have always preferred CWM over TWRP. One thing I saw in TWRP I wish CWM would adopt is doing a "Data Only" backup. I believe you can do the same thing in CWM, but it is a bit tricky. Same goes for restoring just data from a full Nandroid backup. You have use Custom Restore from SDcard and then uncheck restoring everything except Data, select the backup you want to use and then only select data.ext4.tar when prompted. You may see several other files with similar names but with "a" "b", etc on the end of the file name, depending on the size of the data backed up. Do not select them.

I've never tried it, but if you select Custom Backup to SDcard, uncheck all but "Backup Data", you should get a backup of all your apps, settings and data that you should be able to restore to any Android Rom you install or if you have to do a CM Rom clean install for some reason. Again, I have only done this with CM Roms, but I see no reason why it would not work on Evervolv or other Roms. I've done this on CM10, 10.1, 11 and now 12.1 and it worked like a charm. Sometimes an app's icon on the home screen turns generic. Just drag the app from the app drawer again and all fixed. And when I say everything gets restored, I mean everything. Wifi access points, all home screens with all apps just like before, all settings for apps, games, etc.

P.S. If you have any questions about using CWM to install CM12.1 or to do a data only restore, feel free to ask. I' m sure I left something out or did not explain everything fully. TPTB v42 is an awesome tool, but if you already have a data media Rom installed, CWM will do the job very nicely. FYI, I did have /system size increased to 1024mb, but that was strictly on a whim and when I was running CM11. I just checked my TP volumes with TPTB and cache shows size as 200 with 16 used. System shows size as 1024 with 592 used. So 800mb should be enough, but if you have issues increase it to 1024mb.
