[Galaxy Tab 7.7 Android Development] daniel_hk:
Last August, my friend asked me to fix a stuck sim card for this Tab. After that he ask me to install a new system on it. I just do what normally flashing a rom will do, factory reset. After that is a few days of stuggling! He send the Tab to repair and brought a new one. Surprisingly, the dealer replace the motherboard and return it the next week! I was thinking that the support of Samsung is quite good. Feeling uncomfortable, I brought it form him.

Later, I found that It was cause by the faulty chips which Samsung installed. That's why they change the motherboard for me. Its there fault!

This time is much worse, nothing shows up when I press the power button or plug in the charging cable. I think the bootloader is corrupted. May be casued by the recovery I was working on last night.

:(

I hope it can be repaired or I can get another one in a reasonable cost. Otherwise, I can't continue the development anymore... We are on holiday now. I'll send to the dealer in a few days and keep my fingers crossed.

I'll try to finish what I started in any possible way I can. The same friend got a Nexus 7 3g now. He agree to borrow his p6800 to me. But this can only be temperately.

If anyone is interested to help or take over, please feel free to let me know.

I suggest firstly, that wait for service what is gong to do!Will see after that.I cross my finger for you, also.
[Galaxy Tab 7.7 Android Development] carlo67:
ok

which veersion of pa is better for p6800 [pa2.55 or pa3]?
[Galaxy Tab 7.7 Android Development] carlo67:
I installed pa2.55 it is looked good so far . but I got problem with 1 app https://play.google.com/store/apps/...NvbS5uZnllLnJlY292ZXJ5bWFuYWdlci5saWNlbmNlIl0.

this app doesn't work with pa255

does anybody knows other apps like that?
[Galaxy Tab 7.7 Android Development] carlo67:
hi

I have Apex launcher and Titanium Backup ★ root pro.I made a tb backup in cm9 . I restored all of apps and data and it went well on pa. but

I would like to know how to restore all the widgets on pa?
[Galaxy Tab 7.7 Android Development] daniel_hk:
for p6800, pa255 is better for daily driver. Telephony and bluetooth for pa3.0 is not working yet.

for p6810, if you don't use bluetooth, pa30 is a nice choice. It got many new features.

I just have a look on the app Recovery Commander. "Incompatible to your device" appears on the Play store. I think its idea is quite good！But I don't have the Tab to test it for the time being. What kind of issue you have on it? It may be just some settings changes like directory bind.

Widgets are not just simple link. They can't be restored. You have to added it again...

Goodluck !
[Galaxy Tab 7.7 Android Development] gazjglusk:
Can I suggest that if anyone is worried about bricking, then it is a good idea to backup from CWM or Titanium (or any other) to be set to External SD. This is easily done in CWM and in preferences in Titanium.

Default for both is Internal SD and if you have to flash back to stock rom (as I did 3 days ago) you will lose everything on Internal SD.

Another one is ..I use Sygic Aura and the Aura folder with all maps etc is on Internal SD. Once fully set up, copy it to Ext SD as backup ...copy it back to Internal SD and the App works immediately.

This is probably the same with other apps.

Re: [ROM][p6800/p6810/i815] Jellybean Custom ROMs (9/2/2013))

Is data working on any of the i815 roms?
[Galaxy Tab 7.7 Android Development] carlo67:
ok

Recovery Commander was working well with cm9

why I can restored all of widgets with cm9 and tb.?

what about i restored cm9 image back on but this time I don't do factory reset and wipe.?

because I have lot of widgets about 50 . I won't redo them again :(
[Galaxy Tab 7.7 Android Development] daniel_hk:
I don't know if its your case but the content of the internal sdcard is still there. It was moved to /sdcard/0 directory for multi-user support in 4.2.1

After restoring to stock or 4.1.2, you can move them back from /sdcard/0 to /sdcard，I do it all the time when switching back to 4.1.2. I use ES with hidden files on. All the data and settings are preserved.

For double insurance, I also have a backup on PC too.

Goodluck !
[Galaxy Tab 7.7 Android Development] daniel_hk:
You may try an easier way. You can just restore the /data partition, to see what happen. I forgot if CWM support it but TWRP can.

This way you don't have to re-flash everything again.

If doesn't work, you can do factory reset afterward. Still no need to re-flash rom & gapps. The system is still there.

Goodluck !
[Galaxy Tab 7.7 Android Development] sbalu:
I do not understand you.Bricking and backing up datas is two different thing.When tab is became a brick than unfortunately you can not do nothing with it.Even can not switch to download or restore mode.Obviously the method you've written for restore datas when internal sd card has been wiped (factory reset), was very good idea.As for me, I always try to do so, but if you have lots of programs, applications, usually something always lost.In my opinion, the best method would be for the whole system is a working nandroid backup.Maybe TWRP will do it.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Sorry, I don't have the i815 to test but I think its probably not working on 4.2.1 too.

But I think data in pa2.55 is ok. I don't have report yet.

I'll give you a definite answer when I have one.

Have a nice day !

Wifi tether is not working for me

Any idea?
[Galaxy Tab 7.7 Android Development] daniel_hk:
The built-in wifi-tethering is not working.

I built the paTether.apk to support it for pa2.55. However, data is not yet working on 4.2.1, it has to be fixed before any tethering to work.

This is one of my priority, I'll look into it later.

i am talking about this app (paTether.apk) on pa2.55 and also does not work
[Galaxy Tab 7.7 Android Development] carlo67:
unfortunately I don't have TWRP because it doesn't support for p6800. I have CWM.

I don't know any about restore the /data partition, can you explain more please
[Galaxy Tab 7.7 Android Development] daniel_hk:
I am using TWRP on my p6800 all the time. download 2.3.1 from the following link:

http://techerrata.com/browse/twrp2/p6800

use 2.3.1 which is stable. 2.4.0, 2.4.1 didn't boot on my p6800.

flash it with Odin, Mobile Odiin.

I haven't use CWM for months and I don't have the Tab to try it for you now.

If you can't find the way to restore /data only, you have to restore to cw9 and re-flash again.

Goodluck !

Seems silly that this is hidden on a CM ROM.
[Galaxy Tab 7.7 Android Development] johnnobts:
had to switch back to skyhigh ics rom (a great rom btw). While I love the CM10.1 Rom Daniel, the phone is still too wonky for practical use. While I can make calls and hear other people just fine, everyone else I talk to (ATT network) says there is lag and echoing going on and they are annoyed when I call them. Happy to switch back to CM10.1 if these bugs can be squashed. Just giving you a heads up.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have a quick test on 320MHz, work but feel some heat generated. CPU can't U/V too much on this setting. I don't want to add voltage to GPU because it is already hot.

By default, cpu O/C is not activate seems no need to change. I'll include the 300M GPU as standard too.

Might consider a version of programmable kernel later. To add a UI in settings is not difficult but too easy is not always a good thing. Add a file to /sys/power may be my approach. Some cpu/gpu related files are already there. Seems appropriate.

Find out the use of those files would be interesting.

Just installed 12th april version on top of 7th april version and had problems with screen colour on most apps and also touch screen not working properly.

I have done a clean install of 12 april and gapps and my settings. Screen colour problem is no longer there.

However on boot or reboot, touch screen does not respond until I flash sleep on/off, then everything works fine.

Edit : I had set touch sensitivity to 100 (settings/advanced). If I reset back to 50(default), then problem disappears.
[Galaxy Tab 7.7 Android Development] lomniom:
I use directly the link tablet to download the update, but I can't use the mega link. Box also can't be clicked directly using the tablet. And Baidu failed after 30% something. So until now I still can't test the 1204 version. I only can download from dht.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't understand you exactly but using the Chrome browser is OK.

I use MEGA as an example.

After clicking site3, You go to the desktop version at bottom left.

Long press the file you want to download. A menu will appear with the download option.

Click the download and check the File transfers menu at the bottom.

I include some screenshots.

Box is similar.

Possibilities are there waiting for us to explore. Preconceptions always block our minds. Patience and listen with an open mind are what we needed.

Good luck!

Daniel, have you given thought to building CM10 alongside CM10.1? Aorth seems to be building that for the Gtab plus right now since it seems more stable. I'd love to try that and see if its mroe stable for the i815
[Galaxy Tab 7.7 Android Development] daniel_hk:
PA2.55 and CM10 is almost the same but pa2.55 has Tablet mode. Wifi of cm10/pa2.55 was no better than cm10.1. Sleep of death is worse than cm10.1 but cm10/pa2.55 can access hidden ssid.

Aorth mainly changed the wifi driver in the recent build. He was also the one maintaining the cm10 for 7.7. He may post 7.7 builds later.

I was thinking about a new build for pa2.55 but there is no update in the cm10 source since january. The only thing may try is the the wifi driver. I also run out of harddrive space to hold another build...:eek:

Just found a new sensor driver for i815. Don't know if it can fix the auto-brightness...

[Galaxy Tab 7.7 Android Development] 11nn93n9:
I tried to install pa2.55 the past weekend. After installation, it runs. However, I was unable to access the external microsd card. So I installed a third party file manager but still cannot access the card.

Finally, after plugging it into the computer, I confirmed the card is still OK and files are still there. Then, the tablet crashed and I was unable to boot. It gets stuck in the Samsung logo. I tried to boot into recovery, unsuccessful. Installed stock ROM 4.0.4, still unable to boot. But now I can get into recovery. Installed a custom recovery and formatted the /data folder, which does not make a difference. Wipping caches, no help. Now all the options seems are running out. So I took the risk to do a factory reset. It boots after this factory reset.

I used PA 2.55 before, don't know why this time it causes such a serious issue. It could be the third party file manager that mess up the data directory.

Thanks for your help. I bravely did a factory reset after flashing the Hongkong version stock ROM ICS 4.0.4. And now it boots ok.
[Galaxy Tab 7.7 Android Development] currway:
great work

Hello Daniel, i've flashed PA3.15, 12 Apr kernel , and some moderately conservative PimpMyRom tweaks.

What can i say, now it's a huge improvement compared to the pre GPU duplicated step bug fix that you've applied. It's real jelly bean butter now, no questions asked !

I was struggling with simple navigations on between home screens and apps closing/opening on the older builds of CM10.1 ROM, but now on my new set up, it's totally as buttered as it can be.

It's as buttered as my i9100G on an optimised 4.1.2 Touchwiz !!

Very pleased and very glad to follow your journey of porting CM10/PA up to this stage now, you must be a proud dude :)

Hi Daniel!

Just another information and maybe useful git for you: As written original Siyah kernel was not updated for long time and therfore not compatible with maliv2 r3p1 drivers. Now in the i9100 section someone revamped siyah kernel (without this quick'n'dirty workaround to change libs as rush85 did) to be compatible with new drivers and cm10.1 libs!

Besides the old-slow CM kernel and dorimanx git, now a second source for future kernel tweaks is available

[Galaxy Tab 7.7 Android Development] scubajeff:
just flashed 4/12 ROM to replace stock ICS. It's almost perfect except for the following issues:

1. screen orientation sensor seems to have a little bit lagging, especially when after receiving calls, takes serveral seconds before going back to portrait mode from the default landscape mode for phone app; also experience this lagging at lock screen;

2. ambient light sensor sometimes boost the back lit to maximum without any significant lighting change;

3. sony MW600 Bluetooth: can receive and hang up calls, mic is good and can be heard quite nice on the other side, but no sound coming thru. the earpiece, can see the calling number but not the caller ID; music sounds good, and finally i can see the song title on MW600 (this can't be done on stock ICS ROM), but the play/stop, pre/next key has no effect at all;

4. Jabra SP5050 Bluetooth: can receive and hang up calls, but no sound coming thru. the speaker neither. sounds like the Bluetooth stack in this ROM can send whatever data to the device but can't receive anything back.

This ROM is marvelous, thank you very much Daniel!

Downloaded and installed. I am using twrp 2.4.3.0. Smooth installation. I then wiped everything. It boots up without any issue. Once it boots up, I powered it off and installed gapps. Bluetooth works. It paired my M155 at my first attempt. My Jawbone era took a few tries. I had a hard time to have the tab 7.7 to see it at first. It even refused with a error msg of pin error. But I tried subsequently, and it paired finally. Somehow the screen looks sharper with this version than ICS 4.0.4. Maybe it is due to color saturation? Wifi works smoothly. What a great accomplishment.
