Just install it. I haven't even opened the app yet. Try to get the backlight issue when screen off.

Normally I get it when I press the button then move my tab like triggering screen rotation.

Now I cannot replicate the backlight issue after installing Kernel Tuner. I don't do any mod or install any other apps before.

So maybe you should test a couple of days if you see the backlight issue, since C-o-M is still enjoying his holiday season :D
[Galaxy Tab 8.9 Android Development] linw:
I've been trying to reproduce the backlight problem but only managed to see it once in 40+ attempts (Kernel Tuner NOT loaded). So, for me, it is a pretty rare condition thus making it hard to test the Kernel Tuner idea. Tried all sorts of tablet rotations, slow and fast, but it seems pretty stable. Wonder whether the 14 Jul update had any effect??

chienline, can you still reproduce the problem without Kernel Tuner loaded?
[Galaxy Tab 8.9 Android Development] chienline:
Don't know..

I'll try tonight. I'll uninstall the Kernel Tuner and reFlash Unofficial CM-10.1.2 build 07-14 :) and report back here :fingers-crossed:

edit:

well I do it just right now, can't hardly wait until night :D

* uninstall Kernel Tuner

* flash CM-10.1.2 Unofficial Build 07-14 [GT-P7300]

* Wipe cache

* Wipe Dalvik Cache

I see backlight on about once in five tries.

Now I'm going to grant superuser permission to KernelTuner and I'll see if I can reproduce this backlight issue..

[MENTION=3191888]linw[/MENTION] : do you have any other tuning apps installed? other kernel apps, setCPU, overclocking/undervolting tools?

edit 2:

Okay. So I do a more comprehensive test on this issue. [MENTION=3191888]linw[/MENTION] maybe you are right it is random when you say you get one after 40+ tries.

Yes. After reboot, it takes me some time [maybe 40+ like you said] to have the first one. But then it is more often to have the next.

So the best that make sense to me is : when our tab is exhausting doing hard works and begin to slow down, that's when we have a bigger gap between screen off and rotation that can cause this backlight issue.

Then installing tuning apps make the cores works more interactive and narrower the gap.

We'll see what C-o-M get when he get back.

I used to swing-flip my cover just after I press the power button, so now I practice to slow down my move :D
[Galaxy Tab 8.9 Android Development] linw:
It's just too random for me to find a pattern. Did my usual push button and swing it down on its edge to the floor beside me yesterday and it gave a backlight problem but hard to reproduce on purpose. Makes it hard for C-o-M.
[Galaxy Tab 8.9 Android Development] martin707:
Correct. The pattern is too irregular. I would assume this is a graphical issue because of its nature. All fingers pointed to the Tegra driver.
[Galaxy Tab 8.9 Android Development] chienline:
Well, I'm not so sure either. But in my test:

* put your tab in landscape; screen off; screen on -> I can see my lockscreen fired up directly.

* put your tab in landscape; screen off; put your tab in portrait; screen on -> I see black screen with backlight on for a very short period [less than or 1 second] before the lockscreen shows up and then rotates, just like the backlight issue.

That's why I guess the issue is : it is rotating just before the processor sleeps that brings the backlight on [either by Tegra driver or by OS].

Can someone explain the downgrade process to me in layman's terms. I read and reread the 2 and 3rd posts in this thread but I am worried I am going to brick my tab.
[Galaxy Tab 8.9 Android Development] upconvert:
You're probably not going to brick your tablet. Worst case, you'll lose your files, so back up the sdcard to a pc.

I'm gonna assume you have adb. If not, google it. Make sure that adb.exe is set in your windows path.

Boot your tab to recovery, plug it into your pc

Open a command window on your pc.

type adb devices, and make sure your device comes up and says recovery.

Enter the command adb shell. This will open a shell, allowing you to manipulate the sd card files like in a linux terminal window. You can google linux commands to find out more about the syntax for copying, cutting, or moving files. You can also type ls to list the files in the current directory and use the the cd command to change directories.

You should have a # as a command prompt, indicating root access. If not, type adb root.

Enter the rest of the commands from post 2. They will navigate to the sdcard folder, remove the folders that are no longer needed, move all of the files from /sdcard/0 to /sdcard, and then delete the (now empty) /0 folder

Then just flash your ics rom as normal.
[Galaxy Tab 8.9 Android Development] shiko80:
I've seen that you have already updated your repository. Can we expect a new build soon?

Hi C-O-M,

Sorry to burst the bubble, I've just flashed it and 3G/Data toggle is still missing after the flash. I'm absolutely sure I've flashed the correct P7300 build (P5).

Just to give you a scenario on what's going on my side:

1) After flash, tablet reboots and goes to the SIM card PIN (I always secure my sim cards)

2) Then I unlock the screen proceeding to the desktop

3) I notice that the Network bar is full but all grayed out. No H+ or 3G logo on top of the network bar.

4) I proceed to the settings and Data configuration. There are statistics but no Data toggle to turn on.

You see, the ROM detects the SIM and the network. What's weird is that the 3G isn't turning on or have the option to turn on.
[Galaxy Tab 8.9 Android Development] C-o-M:
Can you please try this: (in CWM)

1) Make a backup

2) Format system

3) Wipe data

4) Flash CM

5) Flash GApps

6) Reboot

If it still doesn't work then, can you send me a logcat and dmesg?
[Galaxy Tab 8.9 Android Development] C-o-M:
It's buildable, but my build doesn't boot yet.

I'm also not able to save an APN.

Thx for ur work
[Galaxy Tab 8.9 Android Development] C-o-M:
Can you please send me a detailed bug description (steps to reproduce, expected result, actual behavior and logcat plus dmesg)? I don't own a 3G tab, so it's hard to see the issue for me.
[Galaxy Tab 8.9 Android Development] orlith:
Yes of course but unfortunatly I won't be able to give you that before 2 weeks . Away from the tablets now :(
[Galaxy Tab 8.9 Android Development] shiko80:
I have a P7300 and the same issue. At startup I have to put in my PIN, then GSM/network is on, but the modem seems not to be able to make any connection.

If I switch off and on the modem I only could see the following in the logcat, but still no connection.

setMobileDataEnabled(false)

I have made a logcat and dmesg...

[Galaxy Tab 8.9 Android Development] shiko80:
Do you want me to do further tests or try another ROM. Otherwise I would like to go back to a ROM with working 3G, because I need it again. Thanks!
[Galaxy Tab 8.9 Android Development] chienline:
I have 3g works here. Well I don't really try the connection. I put a prepaid card which is still active but with zero credit.

Here I have blue 3G signal and mobile data option available.

I did dirty flash since the first JB-4.2.2.
[Galaxy Tab 8.9 Android Development] shiko80:
I also have full signal and I also can receive text messages, but I can not connect to the web, that's the big issue.
[Galaxy Tab 8.9 Android Development] chienline:
I have the blue icon, if it doesn't lie then I should have internet connection :D
[Galaxy Tab 8.9 Android Development] shiko80:
Same here, but no connection. Why don't you try it??
[Galaxy Tab 8.9 Android Development] martin707:
The blue signal icon means it can connect to Google Services. If you have a working 3g but no data subscription, why would it show blue? You're the only one with a "working" 7300.
[Galaxy Tab 8.9 Android Development] chienline:
Yah, I'm confused too, why only me have it working :confused:

I just read my prepaid SIM features that I still have free 10MB every morning from 5 a.m. to 9 a.m. on 3G network.

My SIM card is still active until November. 3 months ago I bought it when my wifi network was broken.

Just now I try to reload this page on 3G and it works. Then it turns grey and a message that I have zero balance :D

Seems like operator it reloads my page well before checking my balance :D

I'll try my free 10MB tomorrow morning and confirm if I have my internet connection working or not :)
[Galaxy Tab 8.9 Android Development] martin707:
Strange indeed. BTW, can you double check the CyanogenMod Version number found in the About Tablet?

Mine is 10.1-20130627-UNOFFICIAL-p5

Thanks!
[Galaxy Tab 8.9 Android Development] chienline:
I have it works really. With the latest build 08-06.

And as I mention before, dirty flash, no wipe since the first JB 4.2.2 build.

Strange huh :confused:
[Galaxy Tab 8.9 Android Development] shiko80:
My Version is 10.1-20130806-UNOFFICIAL-p5. But I have made a full factory reset before flashing.

So either I go back to the previous version or flash another kernel.

Can you please check if you have any APNs available?
[Galaxy Tab 8.9 Android Development] chienline:
edit: sorry.. I pressed wrong quote button :D

The screenshot of my APNs ...

Yeah, maybe you should try several builds back then flash the latest without wipes. search this thread for the first JB 4.2.2, I can't remember well the date, but I just did dirty flash since that build, without any wipes or reflashing the gapps, just the rom itself :)
[Galaxy Tab 8.9 Android Development] ealax:
I started to try CM 10.1 and I just installed the latest update and I notice.

no 3G, no APN (adding it manually doesnt work either)

and I tried OTG connector and doesnt recognize the USB stick.

any ideas? I will try to load an old stable version of CM 10.1 to see if at least the 3G works

thanks
[Galaxy Tab 8.9 Android Development] chienline:
Yeah, maybe you should try

* Full wipes

* Flash RC2 build.

* Flash Gapps

* Reboot System and see if 3G and APN works

* If it works then back to recovery and flash latest build without wipes :)

My Samsung USB adapter works good with any flashdisk I have [4GB, 8GB, 16GB].

Use any file explorer with ROOT capability enabled. Find under /mnt

If it still doesn't work try to install USB Host Controller from PlayStore and mount the flashdisk manually :)
[Galaxy Tab 8.9 Android Development] shiko80:
So I have dirty flashed back to CM10.1 final, 3G was working again, dirty flash again to latest version.

No 3G and APNs are gone again :crying: [MENTION=3081699]C-o-M[/MENTION]: Please please help us
[Galaxy Tab 8.9 Android Development] chienline:
Maybe you should try Full Wipes first and flash stable/Final version, then gapps. Then you could dirty flash on the latest.

I read on some CM threads that many people encountered tons of bug especially when dirty flash from different JB version.

Let's say JB 4.1.2 to 4.2.2, or 4.2.2 to 4.3.

Well.. sure it is kind of boring to restore the apps and shortcut/widget on homescreen

If that doesn't solve either, then you should back to stable 3G version and wait for new build from C-o-M :D

I have no idea why only me have it working :rolleyes:
[Galaxy Tab 8.9 Android Development] ealax:
This doesnt work for me either, so I will stay on RC2 for a while until COM fix it :(

after completing a full system wipe, i realized that the scale of the dock icons factor the framerate of the desktop homescreen transitions. The lower the scale, the more responsive it is.

Sloooooooowwwwww....

Hey guys -

After flashing a few ROMS, notably this Cyanogenmod here but the symptoms persist with Paranoid as well - my GT8.9 is slow as it gets.

I typically have to force reboot to get it back to responding after a while. Application switching takes up to a minute at the best of times...

Based on other tests it seems pretty clear that this is I/O, file system related.

Is there a way to check how my drive is formatted (sorry, this tablet has seen many mods and I can't recall all I did before) and what is the recommended format for Android 4.2 or Cyanogenmod 10.*?

Any tips what to test or how to sort out a slow file system? Wiping/reflashing doesn't seem to help a lot...

Thanks!
[Galaxy Tab 8.9 Android Development] Idlekilla:
[MENTION=601705]beluga[/MENTION]: For me Safarikings 4.3 ROM has been the fastest ROM so far (on par with CM9). Perhaps give that a try?
[Galaxy Tab 8.9 Android Development] C-o-M:
Seems like your storage is kind of broken. There might be two reasons: Either you flashed or did a factory reset from an unsafe kernel and got the EMMC brick (that would be a problem). Or your system just needs to be cleaned up.

For the latter, there are some tricks to try warning: each of them will delete any content on your tab, including /sdcard!:

Format all partions in CWM: mounts and storage -> at least do "format /system", "format /cache" and "format /data and /data/media". A factory alone is not enough as it doesn't format the partitions

Flash stock ROM in ODIN with re-partion on. This should recreate all partitions from scratch (though AFAIR the re-partition option is somethings ignored, depending on the ROM you flash)

Install stock recovery and do the factory reset (can also be done from the menu inside the stock ROM). Because of the EMMC brick bug, TRIM is disabled in CWM. The only way to clean the storage on hardware level is to use Samsung's recovery (Samsung says it's safe, nobody can verify that, good luck...)
[Galaxy Tab 8.9 Android Development] -beluga-:
Ok, thanks! I guess I'll proceed with this to do a proper reset (the tab used to run fine on stock back in the days) and then maybe give SK 4.3 a shot as Idlekilla suggested. Sigh, sounds like a bunch of work... :)
[Galaxy Tab 8.9 Android Development] Idlekilla:
Or try the new AOKP 4.3. It's even smoother. :)

Building ROM

Hey C-o-M,

I tried out the build method for 10.2 in this post and it worked just fine. Thx.

I thought I might see if simply changing all the occurrences of '10.2' to '10.1' and then trying to build that would work. (I was very optimistic. :o)

It didn't.

I guess there is a different method required for building 10.1 vs the one for 10.2?

(Is this the method that requires an external ARM tool-chain?)
[Galaxy Tab 8.9 Android Development] C-o-M:
I never did anything else. Replace CM10.2 with CM10.1 in the repo init command and the the local manifest.

Hi c-o-m, didn't understand if the last release is the nightly or 10.1.2...I guess the nightly right? did you already post the poll somewhere about which rom develop?
[Galaxy Tab 8.9 Android Development] C-o-M:
The nightly is newer than the 10.1.2 as you can see from the build dates.

As I said before, I will do a final 10.1.3 build with the fixes backported from 10.2 (those might bring the reboot issue, but I don't care that much).

Regarding the poll: the incorporation of cyanogen made my decision. I'll concentrate on AOKP until it's clear what's going on there. At the moment I'm a bit disappointed. About the #drama, about the fact that a few guys decide what's going in or not (in fact that already has been this way before, they had there secret forums and nobody knew what they are planning), about not telling what the goals of cyanogen Inc are, about the question how they are going to get the money back. I spent some hundreds of hours to bring recent CM versions on this tab. I never wanted anything back. In fact, I don't even use the tab on my own. I just did it because I can (and I got this tab very cheap :D). And I'm happy that a few guys like my work and use it. But I did that all for the community, not for a company with secret plans...

As promised, I'll do one final build. But maybe this will be the last one. We will see. In any case, the sources are open, if anyone is willing to grab it and continue the work - feel free.
