[Galaxy Note 10.1 (2014 Edition) Android Developmen] jm997:
I feel that this should be added to the sticky, or somewhere very visible at least in this thread.. All newer versions of TWRP (anything newer than 2.6.3.3) really do not work on our device, and may actually harm it.

In my case, they "sort-of" bricked my device (lt03wifi, SM-P600 32GB) after a few days: Everything was working but the screen remained black. So sound, ROM, touchscreen, etc. was all working but the screen remained completely black. Download mode, recovery, etc. all worked, but the screen remained completely black even in recovery/download mode. Even the Samsung boot animations were not shown! No amount of resetting, holding the power button, etc. would work.

It fixed itself randomly after rebooting about 30 times the first two times, after the third time I had to open up the device and pull the battery. But every morning after letting it charge overnight, the screen would turn on once or twice and then go black. Note that pulling the battery is really not the same as holding the power button for X seconds, even though Samsung says it's the same. It just isn't.

Is this a hardware issue/Temasek ROM issue?

I'm 100% sure this is not a hardware issue. I am not the only one that had these issues, there are some other forum posts suggesting that the TWRP recovery was the issue for them as well. I'm also fairly sure it is not a problem with the Temasek ROM itself.. All latest versions of this ROM work perfectly fine with TWRP 2.6.3.3, and I have not had this issue in the past 4 weeks since installing 2.6.3.3 (using Temasek v14.3, 20150701-lt03wifi). I waited for weeks to post this forum post to make sure that it really is not a hardware issue, and have tried numerous combinations including going back to stock ROM/recovery (which also fixed the problem). It may be a problem with the combination of CM 12.1 ROM + TWRP, but I don't know as I did not test a lot of ROMs besides this one.

Is this the "sleep of death" issue?

No. It's not the same as the "sleep-of-death" issue that some users have. That one is in fact a hardware problem, and the LCD turns back on after rebooting. Also it seems that with the "sleep-of-death" only the LCD backlight is affected, and not the LCD itself (users report that the LCD is working but the backlight is not on). And finally, it is not the same as the "dark spots" that some people are getting in the lower left side of their displays. Those are also a hardware issue.

Why 2.6.3.3?

After the first time, I went back to the stock ROM/recovery and I let everything be for about a week: no black screens, everything was fine. Then, I installed TWRP 2.8.7.0 and the morning after I had the black screen problem again. So I pulled the battery (by opening up the cover on the back), went through all the threads again, and tried several older versions of TWRP down to 2.7.0.0 (pulling the battery every time). All of them had the same black screen issue after 24 hours. I also tried old versions of this ROM to rule out the ROM itself. I've seen several people recommend the 2.6.3.3 version for this device, and indeed it absolutely fixed this issue. I don't know why, but if you have this issue going to the 2.6.3.3 version after pulling the battery should absolutely fix it.

More details?

I think the problem has to do with the battery charge indicator built into TWRP, the one that turns on the screen and shows a battery charging image when the tablet is off. I think I saw the image a few times right before the screen went black, but not always. Obviously I can't be sure, but it may be a starting point for anyone looking to fix this bug in TWRP.
