This is an unoffical alpha build of CyanogenMod 12.1 for Tab-plus. Let's have the first taste of the colorful Lollipop. :)

Please read "Note on reporting issues" first

For change log, source & donation, please refer to my GalaxyTab 7.7 thread. You may vote for the next ROM to port there.

Note on reporting issues:
1. You need a Factory reset/wipe data after flashing.
2. ART requires longer to boot. Wait for at least 10 mins. in boot animation before hard reset.
3. Check the know issues in my GalaxyTab-7.7 thread first.
4. Post as detail as possible here. Which rom, which model, what happen, etc...
5. With a screenshot and/or video is better.
6. Don't send to my Paypal e-mail. I seldom check it.

Tips:
1. Use ONLY my TWRP2.8.6.x or above to flash.
2. See the 7.7 thread for details

This rom is for users with experience. If you don't know how to flash, please try other ROMs first.

Hasn't worked :( Could you flash it in Heimdall, @daniel_hk?
5.0 use different way to flash. Without modifications, old methods are not working.

I think updater-binary not execute. The same updater-binary works on 7.7. Might be another security reason.

Can you (or anyone) copy the TWRP log to sdcard and send it to me?

1. Reboot to TWRP.
2. Flash the Rom.
3. Copy the log:
Advanced button > Copy log to SD button.
The file recovery.log will be in /sdcard

Oh I understand now why it uses block_image_update().

I will do it after I get home, but there is no other error messages on the screen.

@daniel_hk, here is the log file.

Code:
-----------------------------[cut here]---------------------->8
I:Zip contains SELinux file_contexts file in its root. Extracting to /file_contexts
I:Legacy property environment initialized.
about to run program [/tmp/backuptool.sh] with 2 args
Not backing up files from incompatible version: 12
run_program: child exited with status 127
about to run program [/tmp/otasigcheck.sh] with 1 args
  erasing 212992 blocks
    blkdiscard failed: Invalid argument
  writing 92710 blocks of new data
write failed: No space left on device
lseek64 failed: Invalid argument
I:Legacy property environment disabled.
E:Error executing updater binary in zip '/sdcard/cm-12-20141129-UNOFFICIAL-p6200.zip'
Error flashing zip '/sdcard/cm-12-20141129-UNOFFICIAL-p6200.zip'
Updating partition details...
E:Unable to mount '/system'
I:Actual block device: '/dev/block/mmcblk0p9', current file system: 'ext4'
I:Data backup size is 58MB, free: 12027MB.
I:Unable to mount '/external_sd'
I:Actual block device: '', current file system: 'auto'

It must be due to system.transfer.list OR block_image_update();

Oh yeah, and another thing, the system partition is not correctly formatted AFTER installing CM12 so some ROMs which do not format /system during installation crash with 'Unable to mount /system' too. I presume it's because blkdiscard did not do its job.

I get the same on TWRP 2.8.0

Sreen Rotation

So now that we are into lollipop I figure some light on the screen rotation glitch from KitKat has been shed.
Was the issue inherent to KitKat and therefore the reason the glitch is gone with lollipop??
OR was the culprit causing the glitch fixed outside of the lollipop - ?
If so could the fix be back ported to the kit kat roms to fix the glitch in them??

Just Curious but a non rotating glitch in the latest Omni Kit Kat would be awesome.

    Hi Daniel,

    I was wondering if you are considering developing Android M for the Galaxy Tab series. Thanks!:D
    There is always a possibility. M is quite different from the older version. I believe that's why it is not 5.2 but 6.0.
    I took a look last week. There are a lot of work to do. If I can make it work on my 7.7, I see no reason to left tab plus behind.
    At the mean time, many developers are working on the first custom rom. None succeed yet but I believe soon. ;)

    @daniel_hk
    Everything is working fine including the wifi thething I so dearly wanted but just one more issue short.
    Baseband Unknown seems to be back in this build.
    Tried flashing again and all that and still a bummer.
    Anyone getting this also?


    Me also get this problem when i flashed yesterday.
    also when i checked with *#06#, no imei was shown, only "MEID" at top left of pop-up window and "OK" button at lower left.

    I think I found the problem.
    Solution:
    Use a root broswer (eg. ES file explorer, set the /system to r/w) to edit the file /system/build.prop
    delete the line: ro.telephony.ril_class=SamsungExynos4RIL

    It works for t869 too!

    Good luck!
