The gapps used is Base-gapps build from Daniel-hk but I have tried open gapps in 1st page of this thread, pls choose open-gapps-arm-6.0-nano-20151124.zip, it is really fantastic !!! Work so well with Daniel-hk Omni 6.0 rom build 20151124. Everything fast, smooth ...and display really Marshmallow :)

My way to up new rom:

Use TWRP 2.8.7.1

ROM: omni-6.0-20151124-HOMEMAKE.zip

GAPPS: open_gapps-arm-6.0-nano-20151124.zip

Both 2 zip files above should keep inside micro sd card

Get in TWRP and do steps following:

_ WIPE:

- Dalvik cache

- Cache

- System

- Data

- Internal storage ( because tab 7.7 now mostly for experimental so don't keep any data inside :))

_INSTALL:

- Choose ROM & GAPPS (from micro sd card) then flash

- After flashing then wipe Cache & Dalvik cache

- Reboot System

- During reboot it may hang Omni logo, just keep it run teen minutes and press Start button to restart, it will pass Omni logo fast then optimize all apps and get in setting

- Start setting till finished then set up micro sd card by portable storage funtion (after finished setting sd card logo will appear on start bar, left corner)

- During start using and install more apps, device may be crashed and restarted sometimes, be patient and slowly ....do not angry or worry :)! and remeber recharge tab to full and you can see how well it works!

-GOOD LUCK!!!

does the camera works for u with last build for 6200?

i have done a clean intall with base gapps 14/11 and pico gapps then factory reset with sdcard & sim all work fine & xposed framework but camera issues
[Galaxy Tab 7.7 Android Development] uli-hh:
Camera is working so far. Back camera screen has a green line in the left. but only on screen not on the photos (known issue). Front camera photos are upside down.

I still have the auto rotate problem: after waking up from standby the auto rotate function does not work anymore. Only a reboot brings is back.

I've had some unexpected reboots when installing/starting apps or doing something in settings.

Dear Daniel_hk: rom works so well so far, I have changed a lot apps, disable some, install more than ten new apps, it is still work very fast and smooth but seem just camera have problem, easy to crash and hang on, even I try 4,5 camera apps from thrid party still same problem...after crashing and restart it cause system be slow and heat out more...Just let you know! :)
[Galaxy Tab 7.7 Android Development] p3dboard:
That's because the /system partition can't fit anything bigger. It's where the gapps are being installed. I normally just use pico or nano, or Aroma if i want to choose which gapps are installed

I haven't used this device for some time, but I should say you have done a great job [MENTION=4948627]daniel_hk[/MENTION] ,thank you . I've flashed last build of DU on my p6800 yesterday and so far it's been good. The only problem I'm facing is that I can not send or receive files via wifi which nowadays is very essential. I understand this problem existed even in cm12, is there any hope that this can be fixed in future ?

Also I noticed sometimes UI can become a little slow so I changed min cpu frequency to 500 and it seems that UI is more responsive. I think maybe we should change governor settings for better results (I'm using ondemand and row).

What governor and IO scheduler are you guys using ?
[Galaxy Tab 7.7 Android Development] Lokomia:
I installed the Omni ROM. I think it is better than the CM or DU ROMS. However the tablet gets too hot. Any way to solve it? I tried reducing the maximum CPU frequency but it was not good.
[Galaxy Tab 7.7 Android Development] p3dboard:
I am just using ondemand, i have enabled 300mb of zram (edit: I found that using the built in Ad blocker and leaving zram off is better - the Ads suck up to much ram) using kernel auditor from the play store, as i find this helps with apps like chrome, otherwise when memory fills up, the app either crashes or the system becomes sluggish or reboots.

Sounds like something is running in the background keeping your device awake and probably high cpu usage. Download wakelock detector and supersu to see what's keeping your device awake, and try cpu monitor which is attached to an old post to see what's using up your cpu. It could be a google app like photos trying to upload photos or something else.
[Galaxy Tab 7.7 Android Development] Harrison Le:
For my device P6800 and DU 20160525 is really awesome so far!

And I have recognized that we can not ask an weak old man have to carry heavy things :)

Our tabs were old and low configuration, pls let it be wore a nice suit and do relaxing, don't force it works hard!

Just have an request to [MENTION=4948627]daniel_hk[/MENTION] do an wifi patch to fix the wifi connection be better :)

For anyone that hasn't tried it, Screen Casting / Chromecast seems to be working fine in DU (I just found that it was also working on my old Galaxy S2 under Cyanogenmod 13, so I thought I would test the Galaxy Tab 7.7). I tested mirroring to Apple TV / Clone dongle (Ezcast) via Clockwork Mod's Screen Mirror App (no Audio, just image). Google Chromecast should hopefully do audio as well

Wi-fi troubles

Hi Daniel

Thank you very much for your great efforts.

I've installed cm-13 on my P6200 and I'm happy.

But one thing is terrible: every time it loses wi-fi connection after a long timeout (more than 5 hours). The device's wi-fi system remains on and no network is connected to. I can tap on a network in quick list and it connects immediately.

Have you any idea?

Thank you
[Galaxy Tab 7.7 Android Development] menitin91:
For wifi password forget issue on lastest DU rom, i googled a bit and got ans about making ro.securestorage.support=true to false in build.prop but since i didnt got any such line in build.prop i added it . And it seems after reboot wifi password was still there . (Tried it on P6200).

But it goes after randome reboot.

And thanks daniel for all your wonderful roms .
[Galaxy Tab 7.7 Android Development] p3dboard:
I found that when I wake my device after its sleeping, the Wifi doesn't auto reconnect, but in general, if I toggle the Wifi on and off then it does reconnect. Occasionally it doesn't remember the password.

I just found this post (http://android.stackexchange.com/qu...-forgetting-all-wifi-passwords-after-a-reboot) about devices forgetting wifi passwords after reboot, and if you have a Root File explorer (I am using Es Explorer Pro in Root mode), and you look at /data/misc/wifi/wpa_supplicant.conf you can see all the Wifi connections that your device knows about and the passwords (in plain text). Since my device wpa_supplicant.conf still has the correct details for my wifi, I think that by turning wifi on and off it must re-read this file contents, and thus it knows the correct password to reconnect and it does so. However it seems like its in the process of coming out of sleep that maybe its not re-reading the stored passwords from this file?
[Galaxy Tab 7.7 Android Development] Zets89:
I don't know if someone reported that before, but what's wrong with my p6200. I tried Omni CM and DU and all of them has the same issues (with Delta and Open gapps):

Random soft reboots, and sometimes when there's sound, it crashes, gets stuck and a little part of second gets in like a loop, then I have to force a reboot more than twice per day.
[Galaxy Tab 7.7 Android Development] Niticha:
Omni and CM have problem with wifi-hotspot.

DU with wifi-hotspot=OK.
[Galaxy Tab 7.7 Android Development] braddock69:
P6800:

when i try to install the newest DU always i have errors with the Gaps "not configured".. when i install the omni or cm with same gapps all is ok.

are there specially gapp package for DU?

i tried the open gapps nano and delta gaps... alwys same issue with DU. on omni and CW all is ok :(

i maked advanced vipe and all is clean and fresh
[Galaxy Tab 7.7 Android Development] Harrison Le:
You may do something wrong or some flashing steps not correct!

How you can use CW to flash MM roms with successful!!!!
[Galaxy Tab 7.7 Android Development] braddock69:
i tried this morning other open gapp package for the DU. before i tried the nano and now with the micro package was no errors.

all works fine now
[Galaxy Tab 7.7 Android Development] GNUDroid:
i think this problem had been addressed already. it is related to the limited size of system partition.

bur good that you already found a solution for yourself.

personally i prefer smallest gaaps, pico. this because, if yotube, calendar and such stuff is installed afterwards via playstore, it is easier to use greenify to freeze them.
[Galaxy Tab 7.7 Android Development] braddock69:
thanks for help. yes i prefer the smallest gaps too. on my s4 mini i installed the nano. but on the 7.7 was not possible. i tried so many times with wipe, format and all. the crazy thing is that the omni and cm was installed without any problems with the delta gapps or open nano. but the DU with deltagapps and open nano was not possible. i think i tried 10 times always on a wiped and formatet tablet. was not possible. but with the micro was all ok... dont understand this, but now all is working fine :)
[Galaxy Tab 7.7 Android Development] Harrison Le:
My old man P6800 is really happy to last 2 newest MM roms : CM13 - 20160609 and OmniROM 6 - 20160621, all work well and wifi connection also perfect, just manage RAM seem Omni 6 is better than CM13, try the same apps then comparison and see free RAM on both MM roms as bellowing pictures ( dark theme is Omni and CM is other) :
[Galaxy Tab 7.7 Android Development] F R Harris:
On P6200,

Flash Latest DU, Opengapps Pico, ViperDD+ Sony Beats all together never occur random boots such in Omni rom, and no permission error. The ViperDD+ mod seems to make the default system sound of DU louder (on my P6200 without the mod i could barely hear the screen lock/unlock and home sound). However, using the MoboPlayer (or the system default player) after one or two movies the sound breaks. Like it was muted or something, a reboot fix this issue. When listening to Spotify all day long the sound problem doesn't occur at all, only when watching movies.

All in all, DU is really good alternative.
[Galaxy Tab 7.7 Android Development] p3dboard:
I just noticed that when it didn't auto reconnect with toggling the wifi switch that /data/misc/wifi/wpa_supplicant.conf had a value of disabled=1 against the wifi entry. I didn't manually disable the wifi ssid, so some process must have flagged it as disabled. Either manually removing disabled=1 and rebooting, or telling it to forget and reconnecting makes the disabled=1 go away
[Galaxy Tab 7.7 Android Development] braddock69:
P6800:

with OmniROM 6 - 20160621 all works perfect for me too, i tried OmniROM 6 - 20160621 after the newest DU.

but OmniROM 6 - 20160621 have a problem to read the sim. after start you give in the pin from simcard and happens nothing. then i found out that your sim needs after you give in one time the pin, the PUK to restore the default simpin. i tried different sims and always the same issue. with cm and du all is ok with reading the sim.

i815 SIM Card not recognized

Just wiped - loaded new Omni with gapps. could not format 64GB microsd card for internal use but could for external. Was not sure if i should even be able to?

During initial setup with SIM card already in device acted as if it was not.

Should I be flashing something else for this to work or is this where we are at?

Feels somewhat reactive to touch with small delays here and there. Played with performance setting a bit and got better - will coninute to play with these,

**Just loaded newest CM and it also reports no SIM card found**

I know this device has not always been the easiest to cooperate for connecting 4G.

Wow this release on this tab
[Galaxy Tab 7.7 Android Development] Harrison Le:
I am used end, I don't know about "pin from simcard", "the PUK to restore the default simpin ".... But my P6800 during setting it have recognized simcard and can call/ receive and connect 3G,it worked ferfectly! So what problem with simcard on this omni 6 rom?
[Galaxy Tab 7.7 Android Development] braddock69:
when i start tablet with omi and you come to give in the pin, then happens nothing after pin done. then sim is locked and i need puk. with cm and du no problem, only with omni

OTA Updates

Do the OTA updates work in the Omnirom? Or do I have to use TWRP to get the latest version? If that is the case, I guess I have to install gapps again...

Do the OTA updates work in any of the ROMS?
[Galaxy Tab 7.7 Android Development] aemee:
On a P6800 with the latest DU update.

Wiped clean /system, /data and both caches.

Flashed ROM, Pico Gapps and V4A.

I keep getting freezes/crashes and sometimes reboots when WiFi has connected to an AP. After reboot, if WiFi is not turned off ASAP, it will again freeze/crash or reboot as soon as it connects to an AP. From what I can tell, this happens at random and I am unable to use WiFi for a random period of time before it no longer causes any problems. This happens daily.

I would like to provide a logcat or something for detailed information but I do not know how. If anyone could provide me with information on using app-based logging, it would be very much appreciated.
[Galaxy Tab 7.7 Android Development] p3dboard:
There's no OTA updates, you just have to flash them via TWRP each time Daniel publishes a new build.
[Galaxy Tab 7.7 Android Development] p3dboard:
The best way to capture all the debug information is via the adb interface. You have to enable USB debugging in developer options on your tablet, and then you plug your device in via a USB cable to the computer. Look at http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378 for some information on getting the tools for Windows (http://xdaforums.com/showthread.php?p=48915118#post48915118), Linux or Macos.

Once you have the ADB tools installed, you can run "adb logcat" (https://wiki.cyanogenmod.org/w/Doc:_debugging_with_logcat) and then start up your Android Device (which is attached via the USB cable), and the Android Debug Bridge interface will pass the log data via the USB cable to your computer where you can capture it. You may need to install some ADB drivers for the p6800 under Windows as well.

From memory I think there's some information about this in the Rom Development area that Daniel made.

Hope that helps you capture the issue. I've also noticed that sometimes toggling Wifi on and Off on my P6810 under DU causes a reboot, but I don't get stuck in a constant reboot cycle, it normally just comes back up after a reboot and continues working for a while (eg I had a reboot today, but hadn't had a reboot for a week or so).
[Galaxy Tab 7.7 Android Development] pokazef:
Hello Daniel,

I'm currently using cm-13.0-20160609 on my P6810 and I must say I like it a lot! It's a very nice system, thanks a lot for the release.

My main problem is a nasty wifi bug: every time the outbound wifi traffic goes above about 300 kilobytes per second, the kernel locks-up.

I can very reliably reproduce the problem:

cat /dev/zero | pv -q -L 200k | nc somehost discard # works fine
cat /dev/zero | pv -q -L 300k | nc somehost discard # locks-up

I have tried the above from a debian chroot, so I'm pretty sure it's not android-related. Now the next step would be to get the kernel output somehow, but I don't know how to do that. Is there some easy way of getting a serial port on that device?

Thanks in advance.
[Galaxy Tab 7.7 Android Development] daniel_hk:
That is a known issue. Sending data to a samba host might have problem. App like ES file explorer always fail. Other app like Astro is OK. It was working in KK so it is most likely an issue of our driver since LP or MM. I had traced netd and wpa_supplicant and found nothing yet. Since other apps can survive, I decided to put it aside.

I agree that console port is the best way.

But, there is neither documentation nor circuit diagram which might provide hints. The only thing we got is the generic driver in the kernel source and the pin assignment of the 30 pins port. I have been trying various way to get the serial console working for 2 years. It is not likely using the audio jet as Nexus. There is no signal out in the serial pins of the 30-pins too. I had also tried puting extra code in the kernel, rerouting the console to USB or to a file, etc. Still no luck yet...

Any suggestions are welcome.
[Galaxy Tab 7.7 Android Development] pokazef:
Thanks for the fast answer :)

I found this tread that talks about hacking together a serial connector from the accessory port (for galaxy tab). Have you tried something like this already? I have some experience with the serial console on my Odroid, but hacking a cable like this is a whole new level...
[Galaxy Tab 7.7 Android Development] daniel_hk:
I haven't read it but I think I had tried many more.

If you study the kmsg, you would find the console is hard wired to ttySAC2 in the bootloader.

I made a cable from an existing charging cable. I connected a CRO to the few potential pins. I got nothing after various settings. It might require a pattern or sequence (or an external potential like Nexus) to activate but there is zero info.

After I quit trying the console, I have added extra debug codes to the driver but it just crashed before anything could be recorded.

There is a TESTMOD for Athero 6kl chips. It would fail that too.
[Galaxy Tab 7.7 Android Development] pokazef:
Yep, that doesn't look good. Even assuming we can get the kernel output without frying the tablet in the process, it would still require fixing the wifi driver...

I guess I'll just have to cope with limiting the wifi speed for now.

Thanks again! :)

So satisfied with Omni6 20160621 over 2 weeks and just tried DU 20160707 few hours, it have some issues :

- apps were hung so often while starting, have to reboot then work but seem not smooth and most seriously is Google photos app, it hang all the times while starting even after reboot :(

- same issue to the last build: no memo the wifi password after reboot it's 100% have to retype password

- checking storage & USB found out DU's system files is too big, it's almost triple compare to Omni6 20160621, photos bellowing first is Omni second is DU :
[Galaxy Tab 7.7 Android Development] p3dboard:
Du is showing the system partition size,but omnirom isn't, that's most of the size difference. Notice omnirom is only reporting a 12.95gb size,where as du is showing 16gb

Fix for DU rom video seek, probably omnirom as well

For anyone interested in fixing the video seek issue in Du and Omnirom, i have only tested DU, but omnirom should also work, just extract the three omx video decoder files in the attached omx.cm13-decoder.zip files to /system/lib/omx, replacing the existing files with the ones from Daniels cyangenmod mod 13 rom, set the file permissions to "rw r r" (same permissions as existing files) and video seeking should be fixed for mp4, wmv and avc videos, like videos captured and played in the gallery.

To fix Google Play Drm video playback, i have also attached the 3 updated files that need to go in /system/vendor/lib to replace the existing files. Set the file permissions the same as the original files, once that's done, move the folder in /vendor to /system/vendor and using the App named Folder Mount(root) in the play store, mount /vendor to point to /system/vendor. After that Google play Movies and Drm content in YouTube will work.

These changes require root access and a root file explorer.

Just for any wanting to fix these bugs.

[MENTION=4948627]daniel_hk[/MENTION] may eventually incorporate the code changes that cm13 has that fixes the video seek issues, but there's a quick fix.
[Galaxy Tab 7.7 Android Development] prisoner881:
I see I'm not the only one having issues with the DU 6.0.1 latest build. The ROM flashes fine using TWRP 3.0.0.2 and boots great, pre-rooted and all. But as soon as I try installing GAPP, I get nothing but FC's by Google Play Services and Setup on every boot. I've tried every package I can reasonably find including the ones referenced in the first post and all of them do the exact same thing. Hell I even tried sideloading the Play Store and Play Services APK out of desperation and those FC'd as well. This is on my P6210 WiFi-only Tab 7 Plus.

I'm trying OmniROM now to see if it's any better and I also downloaded the previous 6.0.1 build of DU. If OmniROM works fine then I'll try the older DU build and see if it still bombs with GAPPS.

Any help would be appreciated.
[Galaxy Tab 7.7 Android Development] p3dboard:
Yes, i have the same issue with the current open gapps, i use an old 2016-01-27 open gapps package for Android 6.0,which doesn't have this issue, after that there was a change at some point and gapps always crashes. I have tried Daniel's suggestions about using adb to correct the location permissions but it doesn't work / fix the gapps crash for me.

The older gapps package is my work around. Someone posted earlier how to download an older package, after that google will update it to the current version by the play store.
