This should root your phone .without installing custom backup software.refer to the second entry. Once rooted we can install twrp which is a graphical recovery software that will replace the stock recovery software.

Use root checker from play store to verify root.

Hi Daniel,

Excellent improvements again. Thanks you. Per your request, clean install does not initially show any significant identifiable performance differences and issues with Linaro .

One issue I have found is unlike either of the other ROMs (Slimkat and CM11) this ROM will not read or write a exfat formatted SD Card. The other issue I found is after pairing a bluetooth device and disconnect - upon reconnect the phone will automatically dial the last number dialed.

Also, the CM11 ROM does not have as good as the other ROMs for battery life. Regardless all are excellent. Thanks again for your efforts.;)
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Dear Daniel - huge thanx for your work and for new release of OmniRom.

I installed release of 12.04.2014 with only one wipe - wipe of Dalvick cache. No need in other two.

Some observations

+ Rotation issue is fixed

- Tablet still can`t make software reboot via menu.

If you try - It switches off. It can come to "Samsung P6800..." screen and switches off again

And you can`t switch it on on first, second. third, and more-more times...may be you will be able to make it on 10th time, but I am not sure.

Tab wil make software reboot if you switch power cable in it

Chrome fails

Installed the latest Omnirom and performance is great.

however, i am unable to use the following apps:

1. Chrome

2. Live media player (mdc)

Chrome open and stops automatically, Can you fix?

Thank you Daniel for providing the beautiful ROM
[Galaxy Tab 7.7 Android Development] daniel_hk:
exFat is not my favour but I just checked. Omni has code for exFat which is even newer than slimkat and cm11.(It might be the reason..:D)

I'll take a look later.. I need backup and reformat my tf card first.

Hello my friend,

I have try a few times since your first report. I don't have problem in reboot from power menu.

I guest you have flash on top of an old version. In this case your superuser binary is not activate. It might stuck at reboot.

If you install with my TWRP, root request will appear when reboot after flash. However, you won't get the superuser icon in notification as a clean flash. Superuser apk is working but you need to open it once to fix the binary (I guest it is a symlink problem).

Good luck!

A picture worth a thousand word... View attachment 2685636

If you restored Chrome from say TB, it might be cross platform issue. You might need to clear the data of the app in settings.

It is already mentioned in TB's help.

Live media player. Never try it before:confused: These kind of services are either blocked or very slow in my area. :cyclops:

Might be It's not compatible with Kitkat or else.

Good luck!

I hope this would be the last time I answer similar questions. That would be impossible, I know.. :cyclops:

It is impossible for me test every apk but I'll try if possible.

No, I can't fix it because there is nothing to fix. Even if there are issues for a particular apk, I don't think I'd try. Most of the apks don't have source and even if they have, it might not be rom related. Even if it is rom related, I might not know how to change the rom to work for a particular apk and not affect others. Settings like netfix may be but that's all I can/would do ;)

Don't misunderstand that I have hard feeling. No, I'm not. I cherish any report. Sometimes might feel frustrated when people don't read the posts and keep on repeating the same question. The kids nowadays are very lucky but sometimes fragile and dependent. Most of the parents will provide everyting. All they have to do is to ask or shout. I had been asked for the links of gapps or my other posts, complaining any site can't be downloaded, file can't be opened, etc.

In my life, most of the time we need to do it and/or figure out ourselves. No one would be there for us. We are lucky to have powerful and handy browsers and search engines. Read the posts or search it first is what I'm asking.

Now I'm too tired after a hard day's life...

Have a nice day! :)

UI problem

First of all thanks a lot for your great work.

A little problem though. After upgrading to the latest rom which fixed the rotation issue, I find that the User Interface changed a bit, meaning that fonts and menu sizes are all smaller than those in previous rooms. When I change SETTINGS >> DISPLAY >> FONT SIZE to HUGE, the font size is still smaller than what is comfortable for someone like me with poor eyesights. I am not sure whether this is a problem related to the graphic driver. I hope there is some setting which allows me to change to larger menu and font sizes.

thanks again for keeping my p6810 alive.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, new build set the global dpi to 182 (was 213). Slimrom claim it would be more stable for Kitkat.

You may change back with a root browser.

In file /system/build.prop, change the line back to 213

ro.sf.lcd_density=213

Everything (text and icon) will be enlarged. Need reboot.

If you just want larger text, try:

Settings > Accessibility > Large text

Good luck!

PS. Font size also work for me too. Don't know why yours doesn't work...
[Galaxy Tab 7.7 Android Development] wyfwyfwyf:
sorry for causing the confusion. When I change SETTINGS >> DISPLAY >> FONT SIZE to HUGE, it does enlarge the font size and the problem is just that it is still not large enough for me. Settings > Accessibility > Large text does the same thing.

I will try the ro.sf.lcd_density=213 setting. thanks for your advice.
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Daniel, hello again, i use yours CWM 6.0.4.5 - yes it offer to root device after install new release, i made it - the situation is same..

Will TWRP made by you or SuperSU-v.193_MOD.zip change something? - tryed CWM+SuperSU-v.193_MOD.zip = the same come to "Samsung P6800..." screen and switches off again

But if i long pree power switch and don`t push it off till OmniMan - it`s ok....

Daniel -

i installed your latest TWRP 2.7.0.0, after that i reinstalled 12.04.2014 release of OmniROM + made wipe of Dalvick and yes - root in 2 steps - before rebooting and in first startup via Play method.

But - result still the same

:confused:--------------->

Tab in the same way comes to "Samsung P6800..." screen and switches off again after first reboot after instal twrp+flash, the same situation

But if i switch in power cable and long press power switch and don`t push it off till OmniMan on the screen - it`s ok, i can boot up....

An one more -just now i nserted power cable when "Samsung P6800..." was already on the screen, niot before as always, - and it`s ok, i booted up into system...

Very strange

[Galaxy Tab 7.7 Android Development] daniel_hk:
1.25 is way too old... current version is 1.94. A link is posted earlier in this thread.

That's why I suggest TWRP. It will ask for root before reboot.

Hi Daniel!

I installed your latest omnirom version, I succeded to connect P6810 to my N7000 phone via bluetooth. I wanted to share my phone internet connection with my P6810, I succeded to activate internet sharing between both device but web surfing is impossible anyway, I got a "not connected" message on my P6810. did you succed to make this work? regards
[Galaxy Tab 7.7 Android Development] daniel_hk:
Most of the bluetooth services are from Bluez. I haven't try this way. Wifi-tethering is much more efficient. Faster and consume less power. I suggest you start hotspot in your N7000.

[Galaxy Tab 7.7 Android Development] eugenblack:
Thanks for KitKat on P6800!

Just finished smal (2 days) investigation - unfortunately should rollback.

Migrated from stock 4.1.2 with factory reset. Installed 2014/4/12 build with latest gaps.

Prioritised list of issues:

- Bricked after reboot when all apps from account installed by google. First reboot was ok. Then i rooted device by your zip, installed apps from TitanumBackup. Then rebooted. No startap animation - nothing. After connection power cable it start with old image of battery then transformed into 2d black and white battery. Factory reset fix all - device started normally. Then i started again but finished next day with same result.

- On network operators - network type it start from LTE and search nothing. If selected Auto 2G/3G - list of operators is empty. BUT! Default network detected and data exchange exists and works (3G and 2G).

- Display properties has nothing with our beloved SuperAMOLED. I can't find third party software to maintain it :(

- During scrolling lists some small lags present on left part of column. Like column divided into two parts and one shifted from other. But it is not smooth.

- Device was connected to power during night (5h) but finally reach only 80%battery level. I lost chance to investigate it because as i tried to reboot and ....

Sincerely

Hi Daniel, Wifi is faster but consumes more power than bluetooth

http://lifehacker.com/5967128/tether-your-phone-over-bluetooth-for-less-battery-drain

bluetooth tethering was working on your ParanoidAndroid 2.55cm version.

regards
[Galaxy Tab 7.7 Android Development] daniel_hk:
Can't say much about that. Omni has some residues. Sometimes you need to clear the cache if it can't boot.

Don't know what you meant by Display properties. If you meant the Advance property that can change to touch screen sensitive, vibrate intensity, display senario, etc. It is not compatible with kitkat. Similar devices like i9100, n7000 etc.had remove it from their device tree too.

I was asked to try. It just won't start. Everyone drop it for a reason, I don't want to waste time on this.

If you havent' disable the "alwyas scanning" metioned in TIPS(post#2), you might find drain.

Anyway, stick with whatever you were. It seems more suitable for you.

Good luck!

OK, anything written would become a fact...

I think it's a Russian proverb, "doveryai no proveryai" (trust, but verify).

I read the link you gave. I think it meant the device which provide the tethering.

Anyway, it state a point but without an explaination.

I would say most likely but device dependent. Need to pull out the spec. sheets for both chip to compare. :cyclops:

In your case, you use it as a client connecting to a spot.

By default, kitkat has the "scanning always" on. That means Wifi is never OFF. Even if WiFi is OFF, activities are still there.

In the driver level, wifi has wakelock and bluetooth doesn't.

I can standby with WiFi on for days. That's why I assume bluetooth consume more power. :p

Yes, need to be verified.

As I mentioned before, I only do the porting. I don't want to touch the bluetooth source too much. The Bluez team is working on it. They are surely more capable than me for this. Believe it or not, they have achieved a lot in these few months.

Stick with what you think suitable.

Good luck!
[Galaxy Tab 7.7 Android Development] tetafox:
Hi Daniel!

as you stated, wifi tethering is draining my phone, not my 7.7

I disabled the scanning always option but I cannot standby with wifi for days as you do. Do you have GAPPS installed on your device? Google + seems to be responsible for draining on mine...

regards
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah! Google+ is definitely a drain source. Mine too so I disable it all the time. If you have no account login, it would be even worst!
[Galaxy Tab 7.7 Android Development] tetafox:
is there a way to install your omnirom without GAPPS?
[Galaxy Tab 7.7 Android Development] ninekaw9:
Hi

I have weird kworker cpu usage randomly (can't find what causes it, but occur mostly when it get connected to wifi), and long blue bar cpu usage which make my tab 7.7 become very slow(I had to wait for 5 minutes to be able to play it). Reboot doesn't really help, the problem come back again randomly. This occur on all custom ROMs I have tried, OmniROM 4.4.2, SlimKat 4.4.2, CM11 4.4.2, also BeanStalk based on 4.2.2. Stock ROM doesn't have this problem, but slow GPU performance instead compared to this ROM, just saying.

Also for both stock ROM rooted and all custom rom, my tab 7.7 has random sleep of death problem, after press power button and let it sleep for a few minutes or sometimes for days (both stock rooted and CM based), the tab 7.7 won't wake up. When I was on stock ROM, it doesn't get hot while in sleep of death. For sleep of death in custom ROMs, sometimes it gets hot, sometimes it doesn't. I had to press power and volume up to force it to reboot.

I have 2 tab 7.7 in my home, another one is running on stock ROM and not rooted, and it have never encountered any sleep of death problem.

Another one that has a lot of problem, I also tried flashing stock rom non-rooted via Odin, didn't install much programs, for around 5 days, it doesn't have the problem, but I can't live without root, so I flashed custom ROM again.

And lastly, any Tab 7.7 (I have 2 tab 7.7 in my home) can't connect usb to MSI GE60 2OE(Mine, updated to latest bios)/MSI GE70 2OE(My friend, has exactly spec like the GE60), both usb2 and usb3 port, tried changing usb cable also. It doesn't have problem connecting any other android and apple devices. Both tab 7.7 connect usb to other laptops fine.

Anyone has the same problem like me, and managed to fix it? Is it possible that I have a faulty hardware.

Thanks

[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
I think your out of luck with exfat.

exFAT is an update to FAT32 file system and is commonly found on 64GB or larger sdcards. exFAT has a different and much more restrictive license compared to FAT32. Due to this restrictive license, we'll probably never see exFAT support in the Linux kernel. Many Android manufacturers (e.g. Samsung, HTC) have cross-licensing agreements with Microsoft that allow them to add exFAT support in Android, but that agreement doesn't mean that we're able to add exFAT support for your device in TWRP.

You can reformat your 64GB card to FAT32. You may need to remove the card from your device and use a computer to accomplish the reformat. You also may have to find and download a third party utility to format to FAT32 if you're using a Windows PC. The biggest downside to using FAT32 is that FAT32 doesn't support files larger than 4GB.

If you need a file system that can support files larger than 4GB and works in recovery, you pretty much have one choice: ext4. Unfortunately Android often doesn't handle ext4 formatted sdcards automatically. You'll probably have to mount the sdcard manually using a shell script, GScript (free app in the market), or an init.d type of script. You also won't be able to pop your sdcard into a Windows computer because Windows doesn't recognize the ext4 file system.

You're also welcome to try NTFS, but the majority of the time, NTFS will only mount as read-only in recovery. The Linux kernel doesn't have very good NTFS support either.

Wonder if you could dual partition your ext microsd card - first partition fat32, 2nd partition exfat and get the best of both worlds????

Installed 03.05.2014 (03 may 2014) version of Daniel`s OmniROM

Observations on Tab P6800 with TWRP 2.7.0.0 with OmniROM 03.05.2014:

All three wipes done. Clear Install.

Issues

1)

Tab still can`t reboot normally via Power Menu

. It comee to "Samsung P6800..." screen and switches off. But if you long press power switch and don`t push it off till round logo=OmniMan - it`s ok, you will be able to switch it on..

Tab wil make software reboot

more likely

if you switch power cable in it. When i saw it first time - i did not believe... but i saw it every time on 2 tabs. With normal Samsung 2a wall charger.

2) HUGE battery drain in

sleep mode

- more than 20% per night with switched on WiFi and GPS (sensor of device).

In 30.03.2014 release there was 1% per night

. http://xdaforums.com/showpost.php?p=51628247&postcount=186

In both cases, of course, Wi-Fi Scanning always In Settings > Wi-Fi > menu key > Advanced disabled

3) Today after night i founf my tab fully disgharged when it was plugged on to wall charger with low amperage - it can get only 500 ma from it. With other releases (04 and 12 of april) everything was ok.

4) Problems with mobile data transfer after reboot. Tab can`t finf SIM-card after reboot and i=you will ned to reboot it 1-2-3 times. Switching off Wi-Fi and rebooting цер switched off may be wiil help....

No response

I installed the 3 May version with the latest TWRP. Before that I was still on an older ParanoidAndroid. I have used my tablet a few times since this installation and it worked. But the last time it refused to be turned off.

Every time I turned it off it started itself again. Now the battery is completely empty and the tablet refuses to start. When I plug in the power it shows an empty battery but it doesn't charge. The tablet gets very hot. The only thing that gives some response is holding volume down with the power button and then it comes up in ODIN mode.

Any suggestions what I can do? Thanks in advance.
[Galaxy Tab 7.7 Android Development] GNUDroid:
So at least Odin download mode... That means that you can always go back to stock ROM. I actually do not know how you begin best to setup new

- I think back to stock ROM first and then doing the root and recovery action as first time coming to custom is the best/safest. (Google here xda)

- if you have a backup at your SD card you can restore after that your running custom ROM.
