No, CM has not officially merged bump for the v500 yet. But, this works:

Edit: CM12.1 is now bumped.

Ive *finally* figured out why most of the games wont install from the Amazon App Store. There appears to be a conflict with lollipop's ability to move applications to the sdcard and Amazon App Store. But, there is a way of temporarily fixing it.

Open terminal and type:

su
umount /storage/sdcard1

Now the sdcard is unmounted and all the games can be installed from Amazon App Store. Physically removing the sdcard would also work.

Edit: removed outdated files and replaced with instructions using terminal commands.

A bug I've found is that live wallpapers don't work; the screen becomes proper screwed up. I'll post a screen cap when I get a chance!

Hey guys,

For use as a daily driver, would you recommend sticking to CM11 M12, or is it ok to jump to latest 12 or 12.1 nightlies?

It will be for my Dad, so looking at ROM that won't need to be updated for a while...

Cheers,

Su

Ive *finally* figured out why most of the games wont install from the Amazon App Store. There is a conflict with lollipop's ability to move applications to the sdcard and Amazon App Store. But, there is a way of temporarily fixing it. If you go to Settings --> Storage and unmout the sdcard, then go back to the Amazon App Store, you can install EVERYTHING. So... wait, there is no "unmount" button in the storage settings you say? Ive patched framework-res.apk from today's nightly CM12.1 build (20150420) to add the "unmount" button back in the storage settings like it should be. I dont know why CM has not yet merged the patch I submitted to add this button back in.

Now that's a nice find. The problem is not only with the Amazon app store but with all apks not downloaded through the Play Store. Some install, some not. I've verified this with CM 12 by removing the sd card. I did not have this with AOSP 5.0.2, 5.1 and Stock Lollipop. So this seems to be a bug in CM 12, 12.1 (besides the inability to remove the SD card by software).

BTW: Another obscure bug I encountered in 12.1 is that the date of the reviews in the Play Store (German) is MMDDYYYY (it should be DDMMYYYY). Tried different gapps for 5.1.

There were some problems, but they seem fixed in the new cm12.1 from today (21.04).

Brightness works + playstore keeps crashing everytime I try to start it.

Is there any reason why the newest nightlies don't appear under setting - about tablet - cyanogen updates?

Hi
Currently on 21/04 nightly. Getting random reboots, access internet site, suddenly tab reboots. Has also happened when I was on 18/04 and accessed settings to check for cyanogen updates (which by the way) were showing not available .

Have you tried replacing trebuchet as the launcher? I've had much less problems using Google Now Launcher or Nova Launcher.

CM12.1 has been updated to Android 5.1.1 with latest nightly build.

Updated to 20150422 nightly (dirty flashed over 20150418) and left the tablet on over the night: Battery stayed at 89% over 7 hours. I am facing no stability issues so far.

Great job!

 

[RobaL4]

Currently I flash every Nightly and it is stable so far. Bluetooth reconnecting issue persists, everything else is working fine.

You mean you flashed cm12.1 without wiping cm12 right? I wanna try cm12.1 but don't want to wipe everything.

No. When I first installed CM12.1 (The nightly from 20150416) I did a clean install. Doing so is always recommended when installing a newer version of android.
