I'm going to give this ROM a try! Yesterday I tried an experimental CM12 on a TMobile Note 3 and found it surprisingly usable. When using the TMobile ROM some apps would force close but if older versions of those apps were used (ICS-era) for example, the apps would run fine.

Off we go!

UPDATE: This rom is great! WiFi is fast, works on 5GHz, camera took a picture. SuperSU 2.25 installed via .zip works, have root. ES File manager (lastest version) is working fine.

I notice the screen breaks up sometimes when rotating the screen. The breakup appears as a bunch of little vertical lines on the screen. It almost looks like an effect.

Off to have some more fun!

UPDATE2: Video output seems to be not working: YouTube, Dice Player, Gallery. As another poster indicated, I too get sound, no video -- streaming or local. Might try a fresh reinstall.

P6800 just refuse to die... Thanks Daniel...
[Galaxy Tab 7.7 Android Development] mr-bond:
hi daniel the last rom is very lag and Heavy After the test its Not suitable for everyday use just to late you know thanks.
[Galaxy Tab 7.7 Android Development] LSD DREAMER:
I use mine daily. No problems or even lag on my side p6800. Try a clean install.
[Galaxy Tab 7.7 Android Development] ColBill:
I was have lag problems also. I will do a clean install. Part of my problems i think is the gapps i'm using - could you tell me which version of gapps are you using? Thanks
[Galaxy Tab 7.7 Android Development] mr-bond:
late me know what Happen after a clean install thanks
[Galaxy Tab 7.7 Android Development] mr-bond:
i have Try a clean install and its very lag and Heavy Iam going back to stock rom for now.
[Galaxy Tab 7.7 Android Development] deani77:
You can try 2nd latest updates. It work well for me right now. Been using it since it been released. Download and install latest update, then go back to it.
[Galaxy Tab 7.7 Android Development] p3dboard:
Cm 12.1 i believe is out now, and it's way more smooth than 12.0 was on my galaxy s2 phone, so i think it will be the same on our galaxy tab 7.7
[Galaxy Tab 7.7 Android Development] p3dboard:
The first bug I have found is settings>sound crashes for me. But video playback works, and memory management is fantastic

Edit: also, this could be related to the above bug, when you turn down the volume, normally on my phone, when it gets to no volume, vibrate mode turns on. The vibrate settings are also under sound. It may be not a bug, just a default behaviour. The vibrate for alerting doesn't activate when you hit zero volume

Edit: nuplayer has problems with seeking in videos. Workaround is to enable developer options, turn on awesome player, and then disable hw overlay and enable gpu for 2d.

Edit: Workaround for wifi forgetting details each reboot is the same as i mentioned in omnirom 5.1 test build, use wifi manager app to enter the connection details.

Edit: i have found that stock browser is much smoother than chrome which seems to hang at times. A bug in stock browser, if you set the default page in its settings to show most visited sites, it gives access denied when trying to show this (unless that's caused by ad block which i have installed)

Edit: i don't seem to be getting hardware acceleration in the browser for video playback, mp4 embedded content, youtube is just black but audio plays.
[Galaxy Tab 7.7 Android Development] Steve_max:
I'm getting some incredible slowdown (like the device remaining unresponsive for about 30 seconds between touches), followed by ANRs from (mostly) Google apps. Also, Performance Control just force quits. This happened when I first installed CM12 with PA gapps (that was a clean install of the 14 March build), kept going after formatting system and installing the latest CM12.1 with the linked gapps. Will factory reset and see if it helps, and report back.
[Galaxy Tab 7.7 Android Development] Edwrib:
wifi manager app?
[Galaxy Tab 7.7 Android Development] Zakyz:
Can you guys explain me how to clean install the latest rom? Just found out that this device is still working lol. It's still on android 3.2 Honeycomb.
[Galaxy Tab 7.7 Android Development] p3dboard:
Its an app in the play store, although I have found that under cm12.1, it doesn't remember the WiFi settings every boot. It worked better on omnirom

---------- Post added at 12:09 PM ---------- Previous post was at 11:49 AM ----------

You first need to flash a kitkat compatible recovery. If you look in the thread for twrp and cwm recovery, I believe the latest is 2.8.6.0 for twrp. You should also have the custom ROM .zip, Google apps .zip and I normally have supersu .zip files. I believe there are some step by step instructions around. Be aware that this ROM still has bugs to be worked out, the Android 4.4.4 Roms are more complete. However there is a Google play services issue with the CyanogenMod 11 based ROMs (android 4.4.4) - I have a script to re-enable a service that was disabled, which stops the constant battery drain from Google play services. cm 12.1 (Android 5.1) doesn't require this fix however

Compatibility with Xiaomi Mi Band (Mi Fit APK) ?

Hi :)

First, I want to thanks for the great rom, beautifull, and really fun.

But I experience a bug really anoying ...

I want to use this rom with the Xiaomi Mi Band, but the Mi Fit APK look like having problem with the bluetooth of this rom :/

My problem is when I want to appear the Mi Band in the application Mi Fit, this application still unable to detect any Mi Band arround.

My system bluetooth see correctly the Mi Band, and I appaired it on the system, but still not found in the Mi Fit application.

I tried with 3 differents Mi Band, and still with this problem, when in another smartphone the Mi Band are correctly found.

If any one have an idea ?

Thanks
[Galaxy Tab 7.7 Android Development] Steve_max:
I don't think the Tab 7.7 has the hardware to connect to Bluetooth 4.0 / BTLE devices such as the Mi Band. The protocol is more recent than the device.
[Galaxy Tab 7.7 Android Development] WolwX:
I see, but in the system I can see all my different Mi Band when I do a scan, that's normal ?

Hello dev [MENTION=4948627]daniel_hk[/MENTION],

We are facing a bug (highlighted in red below) that you faced before and would like to know how did you fix it as it will save us time.

2014/11/29
- latest CM-12.0 source, Android 5.0.0_r7 (LRX21Q)
- BLuez port for Lollipop. Working but can't stop after started.
- New RIL libraries hacked from i9300, mobile data still not working...
- Add the PerformanceControl app for our devices (needed ROOT)
- disable PIE checking to allow old executable blobs
[COLOR="Red"]　　- Rotation glitch is fixed. No more flickering when rotation.
[/COLOR]

Devs are working on [ROM][SM-N900][BETA][CM12][UNOFFICIAL] CyanogenMod 12 and there are Rotation glitch/flickering when rotation. (vertical lines of previous frames).

Is it Opengl (buffer) issue?

Thanks in advance :D
[Galaxy Tab 7.7 Android Development] daniel_hk:
I don't have a band so I can't tell which type/protocol. Bluez might not support bands yet.

Yes, It was caused by opengl in cm-11. My cm-12 doesn't have it. I don't know if it is the same bug.

I remember I used a different method in ScreenRotationAnimation.java to solve it. In cm-12, the file is inside frameworks/base/services/core/...../server/wm

It is not straight forward. Better tell your developer to PM me for detail.

Good luck.

Hi danial ,,,

You are really a great and intellegent man here I used all your room on p6800 but I faced a probhlem with all,,,

sch i815 - Data wont connect properly is confirmed.

Tablet sees the local 4g network and sees the strength of it. I get an exclamation mark on top of the signal strength bars when it tries to connect. The install was fine - Loaded all my apps at once and that went well also - While using I did notice a lot of lags - I might go back and try a fresh load with just the gapps and use it for a bit - then slowly add apps testing as I go along for the lags. When I say lag I am referring to the tablet becoming non responsive for a few seconds up to lags as long as forcing you to hold the power button down for a reset.

Been following the roms just not been ringing in - hope all is well - we live in trying times
[Galaxy Tab 7.7 Android Development] p3dboard:
Just letting you know i am experiencing some lockups / freezes during restore of apps from the play store.

Edit: after the install of all my apps it seems to have stabilised. The playback of videos in a browser still seems like hardware acceleration is not working still.
[Galaxy Tab 7.7 Android Development] p3dboard:
Done some more playing. If you enable awesome player instead of nuplayer, and set GPU rendering for 2d and GPU instead of he overlay, then most of the hw acceleration is working. YouTube works great, MX player works with hw acceleration, but some internet video sites like YouTube if accessed via a browser are not working. ROM seems pretty stable for me. Thanks Daniel. Hopefully these minor bugs can be ironed out. Camera video capture works great as well.

tnx danial

Thanks danial this version is more stable then the previous hope this room will be become official one day

I have noted the following three prblms hope u will solve them next time

1 battery consume more then stock

2 after capturing a photo in 16:9 size camera stop working when nned to restart camera for the solution

3 video seeking prblm
[Galaxy Tab 7.7 Android Development] p3dboard:
If you turn on awesome player in developer options instead of nuplayer you can work around the video seek problem

[Galaxy Tab 7.7 Android Development] p3dboard:
Downloading new build to test it out. Hopefully, the reboots / freezes are gone in this build and i can switch from Android 4.4.4 to 5.1.1 for daily use. Thanks Daniel.
[Galaxy Tab 7.7 Android Development] p3dboard:
I just worked out that my freezing and I/o issue is to do with having my micro SD card mounted. If I unmount the SD card, my lag and general performance issues go away. Android 4.4.4 didn't have this issue. My card is a 32gb class 4, Kingston brand. Possibly with it mounted, something is constantly accessing the card? The I/o performance of the card is much slower than internal memory. I have checked via CPU monitor that the mediacscan completes, so it doesn't seem like its media scanner that's the issue.

Any idea's on what this could be?

Can anybody help me with a hint?

Thank you,

[Galaxy Tab 7.7 Android Development] p3dboard:
You probably need to flash twrp, instead of cwm recovery. It's in the threads, i like the twrp interface better anyway and it's updated regularly where as cwm isn't anymore.

Thanks for the hint. With TWRP 2.8.6.0 the upgrade was succesful.

Developer Options

Flashed successfully. But I can't find "Developer Options" anywhere in Settings. How to enable root?

UPDATE: Oops, just found out how to enable.
[Galaxy Tab 7.7 Android Development] uli-hh:
It is the same as in KitKat. Go to Settings>About phone and hit the build number 7 times to unlock things.
[Galaxy Tab 7.7 Android Development] sanykool:
Ok, I test it for two days. Actually, the great job was done by daniel_hk, but...

1) The problem (black screen) with hardware video decoding should be added to known issues, I think. Workaround: Use VLC Player with forced software decoding option.

2) Hungry apps often freeze. E.g. the trick with "ok, google, route me home" takes eternity before navigation really starts, you gonna be home already by that time.

3) Phone app is too slow and unresponsive. I could not hang up the call for long several seconds.
[Galaxy Tab 7.7 Android Development] deani77:
Most of the issue was due to our old hardware... It was a miracle it can survive until 5.1.1 version.... Samsung already abandoned us long time ago.

Thanks to Daniel for make it happened.

As for hardware decoder you need to tick use awesome player and disable hardware overlays... Been using this setting with MX Player without problem so far...
[Galaxy Tab 7.7 Android Development] Phobos Exp-Nord:
No matter what is the reason, this is a valuable problem and should be at least highlighted. Really, it's not possible to play youtube or social network videos, and offline videos are played in software mode which drains battery much faster.
[Galaxy Tab 7.7 Android Development] deani77:
I have no problem watch YouTube or watch video using hardware decoder....

Sent from CM12 GT-P6800
[Galaxy Tab 7.7 Android Development] Phobos Exp-Nord:
Can you please point me somehow to the ROM image you've used, as I experience the problem with Omni 5.1 and also tried some CM 12, but without success.

Upd. Nevermind, just found that the absolutely latest CM12.1 offers not perfect but optimal video playback features: with enabled HW overlays and disable NU it allows to play youtube with linear filtering, VLC with full hardware and MX in software (MX works in hardware without HW overlays, but this makes youtube videos resized with nearest point filter).
[Galaxy Tab 7.7 Android Development] SPVlover:
After CLEAN Install, here are my findings..

Well, first of all, THANK YOU Daniel for your fantastic work.

I've had some issues with this latest build, notably the I.o problem, freezes and difficulty to use the tab in general because everything was sooooo slow if it even worked( read the thread for detailed description of the problems).

Now however, I have decided to start completely new.

I've mounted and wiped system, cashes and data several times to be sure, through TW recovery (latest).

I've reinstalled this lates CM12.1 ([ROM][p6800/p6810/i815](2May2015)CyanogenMod 12.1 Unofficial) build, the gapps from omni (5.1.1 i believe) and the super su update 2.36.

after the first setup, the thing files. no memory problem, no freezes, No nothing.

Its very very usable in all aspects.

Just as a heads up, try this combo , install one after the other (I've rebooted recovery after each install)

I am a very happy camper with this so far.
[Galaxy Tab 7.7 Android Development] p3dboard:
I took your advice and tried cm 12.1 again with the delta gapps. I was using older pa gapps. So far it's behaving nicely, no i/o lockups. I have tested real racing 3,as it's fairly resource hungry and it seems ok. Will see how it goes over the next few days. May have been an issue with the gapps, and not cm 12.1
[Galaxy Tab 7.7 Android Development] massdown:
how is it going with your tablet ?! have you noticed any slow down in performance

i've the stock rom on my 7.7 and want to be sure when install the lollipop that there is no delay in performance .
[Galaxy Tab 7.7 Android Development] p3dboard:
I didn't experience any of the old I/o freezes during my testing, but I deliberately kept a few google apps like google+, google search off my installation, as I know these can cause a bit of issues at times. I had a few issues with video playback still, so I went back to slimkat 4.4.4. I also found that chrome wasn't as fast as under slimkat. Definitely much better than my last test of this rom

If you do it right there will only be TWRP-Recovery.

[Galaxy Tab 7.7 Android Development] uli-hh:
If you go to the TWRP-thread you will find the download links for the latest TWRP2.8.6.0. There are 2 different files available. One zip-file and one tar-file. Underneath the download link you can find the explanation for the different files:

Tar format: flash with Odin or Mobile Odin

zip format: flash in CWM or earlier TWRP

So because you have already installed CWM you simply download the TWRP zip-file and save it on SD memory. Then boot into CWM and install TWRP from these zip-file.

If you now boot into recovery again you'll be in TWRP-recovery and you can install the Lollipop rom correctly.

Did you notice that with lollipop 5.1.1 there is the performance control app installed and the CPU speed normally is reduced to 1200 MHz. So you can first set the CPU performance to max there and see if your tab is quick enough then.
