There is very little possibility of getting Miracast working. Other screen casting technology might work. Miracast requires the device to support two important things. One of which is a newer audio HAL so that remote submix support can be added.

The second is WIFI Direct. This one is very broken on our device. To fix it is impossible because the kernel WIFI driver is a massive complex of code. On top of that, Samsung deviated greatly from the stock implementation. So backporting fixes from upstream kernel are impossible to accomplish. I have tried to fix it back in KitKat without any success.

Chromecast might work? I think someone already mentioned trying it but it was only working with a couple of apps. I'm not familiar with how it works but if Chromecast also depends on WIFI Direct then we are out of luck. I was under the impression that it didn't use it though.

Thanks a lot decatf!Smooth ROM with no problems re: dirty flash over the old ROM with reinstallation of gapps and superSU, wiping dalvik cache afterwards b4 rebotting system. WIFI SSIDs and passwords intact as well! Kudos for a job well done and your efforts to keep our tab up-to-date. Happy New Year!

Thanks a lot decatf! Smooth ROM and no problems after dirty flash over the older version. WIFI passwords intact. Steps followed: installed experimental version, gapps and superSU then wiped dalvik b4 rebooting system. Kudos for a job well-done and your efforts in maintaining our tab up-to-date. Happy New Year!
[Galaxy Tab 10.1 Android Development] orkan95:
Any idea why some people have the issue of loosing their WiFi credentials with the newest built and some people don't?

Also one other issue: the ROM doesn't store it's settings into my Google account. So I need to manually adjust everything after a clean installation. In "settings > backup&restore" the option "backup account" (I hope the translation from German fits) is inactive/grey.

Yeah, I can't wait to flash this. Can someone please reupload the rom?
[Galaxy Tab 10.1 Android Development] decatf:
I've put up a new p4wifi rom. I had taken down the first release since people were having problems getting back into recovery.

It's now using the old installer script. So you can install it the usual way. Wipe. Install the ROM. Then reboot. The p4 ROM will be shortly.
[Galaxy Tab 10.1 Android Development] CraigWiggins:
First impressions- overall good

I upgraded from the CM4.4.4 rom, which was "perfect" in that it ran everything.

Overall, the flow and speed of this rom is quite good- especially given the hardware age. I *DO* have a Netflix account, and can verify that it runs great on this rom.

Bluetooth audio, however, is not working. It pairs with my Memorex MW212 speaker, but the audio does not go through. This was working on the CM kk rom, and works on either Omni or Nameless, though I forget which (sorry), both KitKat.

I already had TWRP installed, and the flash went without incident, though I also noticed the inability to boot back to TWRP without the "two finger" hardware method, which always works. I'll flash on your update, or more likely just wait for the next update.

Great job and thanks! I once again have the most advanced device in the house.
[Galaxy Tab 10.1 Android Development] tomerstern:
Thanks so much!

Just installed the new file using CWM 5.5.0.4 and it worked perfectly.

Recovery

I just flashed it last night with CWM and I got the dead android image where the recovery should be. Does anyone have any easy tips for me to get back my recovery? Also will all my files get wiped? Thanks for the help
[Galaxy Tab 10.1 Android Development] MicheyM:
I am currently on stock 4.0.4 and rooted along with CWM 6.0.3.1 , would it be possible for someone to tell me (here or via private message) how exactly i can backup and then install this (step by step) please! I am sorry, i have not installed a rom before and help would be much appreciated!
[Galaxy Tab 10.1 Android Development] l_4Fhit_l:
I would watch a tutorial on CWM. Esentially you need to make a backup through CWM and install a zip file.
[Galaxy Tab 10.1 Android Development] Gil81:
If I was u, I would first update to twrp recovery. It is the best recovery for this device, in my opinion. Twrp 2.7 is very stable and the recovery I use to flash all ROMs.

1) Download twrp recovery from here. Scroll down on post 1 until you see slim recovery. Pick the correct version for ur device..( p4=3g tab )(p4wifi= WiFi only tab )

1a) Now check the md5 of the recovery zip download ( if it has one ). FYI: Es file manager is good to use for checking this

1b) Boot to recovery and wipe cache and dalvik cache. ( dalvik cache is under advanced )

1c) Flash/install the twrp recovery zip..when it is finished. Go to advanced and pick Reboot recovery. Done.

1d) After twrp boots back up. You can now make your backup. Directions at bottom of post.

2) Download this ROM and gapps from links in OP.

2a) Check md5 on both downloads.

3) Boot to twrp recovery and pick wipe..then pick Advanced.

3a) Select cache,dalvik,data and system..( Do Not Wipe Sdcard ) I do this twice.

4) Flash/install ROM you downloaded..after it is done. Pick wipe cache and dalvik. Then pick home.

4a) Now pick reboot...next pick recovery. Device will reboot back into twrp recovery.

5) Do the ROM install again..wipe cache and dalvik after, again.

6) Now go back to install and pick the gapps package zip..install that zip.

6a) When it finishes..wipe cache and dalvik. Pick back.

7) Pick reboot...or go to your home page and pick reboot, then system. Device will reboot to newly installed ROM.

8) Go make a snack and let the device chill out...it will take 5 minutes plus for this ROM to boot.

Whoops..forgot to tell you how to make a backup in twrp.. After you pick reboot recovery and twrp boots up. Pick backup. Leave the selected options ticked and make your backup. Easy Peezey..Lol

---------- Post added at 08:07 PM ---------- Previous post was at 07:36 PM ----------

If you can't get to recovery the manual way...then just Odin a recovery tar.

After it finishes..the ROM won't boot..but you should be able to boot to recovery and flash a ROM to get you back up. Then redownload the rom from the new link and try again. I would flash twrp 2.7 to use for the next flash and all flashes there after.

No data will be lost.

---------- Post added at 08:14 PM ---------- Previous post was at 08:07 PM ----------

Whew...lol

OK. I'm really liking some of the new features I see with 5.0

ROM is smooth and pretty responsive...

But no theme engine is a deal breaker for me.

Great job though dev...looks great. Can't wait to see where this rom goes from here.:good:
[Galaxy Tab 10.1 Android Development] SystemDoctor:
So after the tab boot I just flash gapps right?

EDIT: NVM, I'll just redo the installation if this fails. Is it alright if I flash gapps after boot?

---------- Post added at 10:46 AM ---------- Previous post was at 10:17 AM ----------

Successfully booted Lollipop! Now it's to to SuperSU!
[Galaxy Tab 10.1 Android Development] Gil81:
Some ROMs OP ask that you boot the new ROM up and let it settle for a bit..(5 to 10) minutes. Then boot recovery and flash gapps. Some say you can flash gapps directly after you flash the ROM. Then boot up.

I myself always flash the gapps after I have let the ROM settle in for a bit.

And you always flash the ROM first.

Updated Recovery Deletion

I got my computer/odin to recognize my tab by changing the position of the device because the USB cable is sort of messed up. I then flashed an older version CWM (4.0.0.4) which I used to initially root my Tab and everything passed and all. Then when I went to my recovery, I had the dead android thing again. I'm thinking the old recovery is just not compatible with this OS hence why it was deleted in the first place. I tried finding other recoveries but I had no luck. Odin log:

<ID:0/003> Initialzation..

<ID:0/003> Get PIT for mapping..

---------- Post added at 01:45 AM ---------- Previous post was at 01:16 AM ----------

I also tried some other older custom recoveries..... still no luck.
[Galaxy Tab 10.1 Android Development] decatf:
I use pershoots old recovery when I need to. He still has them hosted on his site. http://droidbasement.com/galaxy/roms/cm10.1/

Use the recovery.tar.md5 under the directory for the version of the device you have.

Edit: Technically there should be no problem using old software since the hardware has not changed ever. If the USB cable is indeed bad then there's a chance of bad data transfer when flashing.

Build 20150101

p4wifi-lollipop-20150101.zip

Mirror

p4-lollipop-20150101.zip

Mirror

Changes:

Fix memory leak in system_server when screen on/off. reference.

Add DSPManager app

Add missing Java library needed for Bluetooth

Add the new Lollipop audio HAL

Add audio remote submix policy

Build the standard audio policy manager instead of the legacy audio policy manager

Fix email combined view crash

Additional notes:

- For p4 tablet users who downloaded the 20141227 experimental build: I am sorry but I bungled that build. The new audio HAL didn't even get included because I didn't remove the old one. The current build should be compiled properly now.

- I am including the new audio HAL in regular builds now. To go back to the old ICS audio just install the p75xx-ICS-AudioHAL-20141222.zip package.

- The new audio HAL doesn't support audio input effects processing yet. I can't even find any application that uses it so it's untested. Therefore it is not enabled.

- SPDIF out is not supported in the new audio HAL because I have no reference on how it is supposed to be implemented.

-

If there are any problems with the new audio HAL then please save a logcat and send it over.

If we can get it working without many problems then we can get rid of the old ICS audio blobs forever. This will make it easier to port present and future ROMs.

- Bluetooth file transfer wasn't working because there was a Java library missing.

- Audio remote submix is required for wireless display. The built in wireless display is NOT working. However, remote submix might be useful for other things like Chromecast. I am not sure if it needs it but those who have Chromecast or try with it please report your results. And send over a logcat if it doesn't work.

- WIFI breakage: I can't reproduce the WIFI problem that happened with the 20141227 experimental build. But if you're still having problems then trying deleting the config file in /data/misc/wifi/wpa_supplicant.conf. You need root access to delete it.

su -
rm /data/misc/wifi/wpa_supplicant.conf

Or enable root access mode in CMFilemanager and delete it through there. The wifi configuration and your access point passwords are stored in this file. After deleting, it will be recreated on reboot.

Experimental TWRP build:

Changes:

Merge changes from Omnirom/android_bootable_recovery

I was searching for a fix for Netflix error -9 which sprang up for me this week on my Galaxy Tab 10.1 wifi running p4wifi-lollipop-20141222 posted by decatf --- and on my Nexus 4 running Resurrection_Remix_LP_v5.2.6-20141229-mako posted by Rodman01.

It looks like it's two DRM related libraries. I can't tell much more than that at the moment. It seems like proprietary libs but if it does fix something with Netflix then I could add it to the build.

The memory leak bug is marked by Google to be fixed in a future Android release. I have added a patch from CyanogenMod that addresses the issue. There is no guarantee that it is fixed properly.

p75xx-Lollipop-AudioHAL-20141230.zip was removed because it is included in 01/01 build. Try removing the device and pairing again. In Settings>Bluetooth long press on the device and press "Forget".

[MENTION=4404851]decatf[/MENTION]: I have used your AOSP build since the start and I am mightily impressed in your product. Stability and smoothness throughout. The only drawback is an app-quit (Hay Day for example), throwing me without any notification back to the home-screen. As this only happens VERY sporadically it is both hard to trace/logcat and not really an issue. Could be related to the memory leak bug, but not sure.

Loading your 1/1/2015 release now on one of the p4wifi's (got a few), and I prefer this release over the Omni version of [MENTION=2931572]AAccount[/MENTION]. No real reason, just a little bit smoother (as far as I can see). Testing the TWRP 2.8.3 as we speak...

Love the product, and keep up the good work of getting the "Mastodont" p4(wifi) a new lease on life. Coming from the Nameless 4.4.4 I still need to get used to some of the vanilla setups (like extended reboot options missing for going directly to TWRP and one or two more), but hey, apps can take care of all that. Running Nova launcher. Overclocking with the old 0.7.0 device control works dandy and is stable up to at least 1400. Not sure if the latest Device Control App will work fine on this Lollipop release, but not really willing to take the risk.

Thanks again and looking forward to new LP releases.

-- EDIT --

[MENTION=4404851]decatf[/MENTION]: It seems your build date (of the 20150101 release) is still on 22/12/2014 (and the other date in the info is on 25/12/2014 - kernel date?). The newer ROM image is larger, and I tried to flash both the xda-download and the mirror download one to see if that made any difference: no diff in date. Is this an omission, or just intended to be so?

Where are you checking the build date? The kernel date did not change because there were no changes to the kernel so it was not recompiled. Thus the kernel date remains when it was last compiled.

Is there something wrong with the p4 20150101 build?

Usually there has been more downloads on the p4 build. But the 20150101 build currently has 290 downloads compared to 2816 for the p4wifi build. I double checked the MD5 for the p4 build (174ceb903d82ba60ae1f5bdb52fd2fab).
