I've run into a major problem with this 5.1.1. It seems that eventually something happens that causes the app optimizer to happen at every reboot and it never successfully completes. In order to fix this I have to wipe data and cache.
[Galaxy Tab 8.9 Android Development] filipe_m:
I have a similar problem:

Each time i turn the tablet off to reconnect i have to press 6 or 7 times the power button. After that appears the logo of Samsung and after stays on a black screen.

I have to continually press power button to restart, this time everything works fine until it gets to optimize all applications... take a long, long time and start to work ok...

This happens each time i turn it off, repeated all the steps and the same order...

Any solution?

Thanks!!
[Galaxy Tab 8.9 Android Development] swaaye:
There's no solution that I know of. You should probably use a different ROM. The 4.4 Kitkat ROMs seem more reliable.

In fact, the first post of this thread has a LiquidSmooth 4.4 that seems to work well.
[Galaxy Tab 8.9 Android Development] filipe_m:
Which Kitkat you refer?

All who tried had problems with video recording in HD .... the results were videos with color spots
[Galaxy Tab 8.9 Android Development] jolinnard:
New update

After the summer, it's time to port latest from decatf. So, here it is:

decatf's AOSP ROM:

aosp-5.1.1-p5wifi-20150814.zip

aosp-5.1.1-p5-20150814.zip

decatf's GAPPS (without selinux contexts):

p75xx-gapps-L-7-17-15_selinux_OFF.zip

Figue kernel v18:

Figue-boot-v18-p5wifi-L.zip

Figue-boot-v18-p5-L.zip

Changelog:

- This time, I rebased the kernel to decatf's stable tree. Applied CPU OC/UV patches only. CPU governors and schedulers are the same as decatf's p4 kernel.

- Graphite optimizations seems to work fine :good:

- Disabled zram and KSM/UKSM.

Happy flashing.

Did a dirty flash (sorry), but tab stayed on bootscreen.

I got stuck on bootscreen as well with a clean install twice.
[Galaxy Tab 8.9 Android Development] jolinnard:
Did you flash p5 or p5wifi? If you dirty flash previous version it works again?
[Galaxy Tab 8.9 Android Development] L3R0N:
In my case I simply flashed Figue v17 and the Tab booted. And both versions got stuck on bootscreen for me. Don't know what went wrong.
[Galaxy Tab 8.9 Android Development] Nonomen:
P5wifi. Restored the TWRP backup.

[Galaxy Tab 8.9 Android Development] filipe_m:
I tried to install in the recovery and gave me an error...

Installation by adb went well.

The previous problem to turning on after being off no longer exist ... neither the optimization Apps issue...

A good improvement for me...

Only a problem with battery: shows 60%, after 20 minutes 15% i reboot the tab and shows 70%... need calibrate and hope it improves!!!

[Galaxy Tab 8.9 Android Development] jolinnard:
That's odd... I tested that kernel as usual (in my own tab).

Can you check if you have these files?

/system/etc/init.d/00random
/system/etc/init.d/99power_opt

and what permissions have? I removed two lines in kernel updater script (because latest decatf ROM doesn't have them). In previous ROMs those files cause boot failures.
[Galaxy Tab 8.9 Android Development] jolinnard:
Good to hear!

The battery is a common issue that I have since last year. Sometimes it seems charge in recovery helps to maintain battery calibrated. Sometimes it's a mess... Try to drain your tab until it powers off (for instance you can leave tab in recovery/Odin menu, when you start it with vol. up button), or in recovery set screen to max brighness and no sleep. Then boot with AC the tab again in recovery and wait until it's full. Shutdown the tablet again and leave the cable with Android started for some time. Then unplug and check if battery is consistent...

I unplugged battery twice too, and that gives me some cycles of good battery (battery chip needs a reset sometimes). But it's a bit difficult to open the tab... There are videos in youtube, but you need to be careful if you never opened a tab. The screen can be easily broken...
[Galaxy Tab 8.9 Android Development] filipe_m:
Thank you!!

I'll try!!
[Galaxy Tab 8.9 Android Development] librapt:
I did a clean install of the new build (I'm on p5), factory reset, flashed the rom, gapps and superuser. Tried to flash the new figue v18 too, but it gave me and error. After that, my tablet booted for like an hour straight. I was just about to decide this was a bootloop, it booted, but it was lagging so much, I couldn't even get past the first configuration. Tried to flash again without the kernel, did a factory reset, flashed the rom, gapps, superuser, but the same thing happened... I'm using TWRP (possibly 2.7.1.0?). Any thoughts? :(
[Galaxy Tab 8.9 Android Development] jolinnard:
Can you try with p5wifi ROM and kernel?
[Galaxy Tab 8.9 Android Development] L3R0N:
I have the issue as well. Currently using v17 and all is fine.

I have the issue as well and I tried both p5 and p5wifi roms and kernels. For some reason if I flash just the ROM only the Tab doesn't boot but if I flash the ROM and the figue-v18 kernel the Tab boots after a long while. There is huge lag when doing certain things while others just work...but it lags like 95% of the time and the other 5% is for things like returning to home screen and opening certain apps. I took a logcat while using the device in hopes that it might catch whatever is causing the problem. Check it out here

Also sometime back decatf said he was willing to build a kernel for our device however he doesn't know how similar the two devices are...I don't either but maybe you do since you build from his sources. Maybe if you give him that info he could also build us a TWRP as well.
[Galaxy Tab 8.9 Android Development] jolinnard:
Ok, back to stable build for now. I don't know why it's happen this lag in your p5.

Basically I just take decatf config and remove/add devices/chips/etc that p5 motherboard has. I can make a diff if decatf want, but I doubt that without a p5/p5wifi he can help. Anyway, you can give that config too, just adb pull /proc/config.gz ;)
[Galaxy Tab 8.9 Android Development] librapt:
Would you be so kind and give me a link to the v17? :) I can't seem to find it. Gonna try that, see if it works for me. Also, I have a cast stick for my TV, tried to cast my screen, but it just won't show any device in the cast screen setting... All my other devices (phone, laptop) can easily connect, the tab's the only one having problems... :( Do you have any suggestions?
[Galaxy Tab 8.9 Android Development] L3R0N:
Alright then I'll share our device config with him and see what comes out of it. I'm really hoping that its all he needs to build us a kernel and possibly a new twrp.

You can find v17 kernel here . I think screencasting is broken on these ROMs check the p4 thread I think decatf mentioned something about that somewhere.
[Galaxy Tab 8.9 Android Development] mightyfreak:
First of all thnx for the rom/kernel/recovery. I installed aosp-5.1.1-p5wifi-20150513.zip and everything works fine , except GPS doesn't work. Is there a fix for or is it only me.

Update: I installed GPS test and went outside for 15minutes and it's working! It was just me.
[Galaxy Tab 8.9 Android Development] bluefalcon13:
Jolinnard, thanks for the awesome work. This has breathed new life into my tablet. Just installed today, and using my e-textbooks is about a million times less painful!

On a side note, using the kernel you listed in the main post, SuperSU, and a 200mhz overclock, connecting the tablet to the keyboard dock results in an instant hard lock. Don't know if you are tracking that or not. Not a huge deal for me cause I just use the keyboard dock to charge my tablet.
[Galaxy Tab 8.9 Android Development] jolinnard:
Yes. Dock issue is a known bug. I don't have a dock to make tests and I don't know what could be the cause. If you have some logs or ideas to fix it I can try.
[Galaxy Tab 8.9 Android Development] bluefalcon13:
I'm not even sure it is logging the crash. Complete hard lock upon insertion. Can't even turn off the screen. Not a deal breaker by any means, but if you want me to dig for the logs I can. Just point me where to look.

Which is the latest ROM that 3G works at the 7300?
[Galaxy Tab 8.9 Android Development] asurabp:
Hmm i cant seem to download any nameless 4.4.4 rom in the op. :/

Sent from my tomato
[Galaxy Tab 8.9 Android Development] jolinnard:
Latest Nameless I built are here

I think that [MENTION=5944750]L3R0N[/MENTION] port some ROMs after those releases.
[Galaxy Tab 8.9 Android Development] L3R0N:
The one in your link is the last Nameless ROM for our device.
[Galaxy Tab 8.9 Android Development] :
I installed LiquidSmooth and decided to go back to ICS, but it wouldn't boot. I realised it was because the /system and /cache partitions were formatted as f2fs. I tried changing them back to ext4, and apparently it was successful, but it said it was still f2fs.

EDIT: Flashing NamelessROM formatted it back to ext4. Never mind.
[Galaxy Tab 8.9 Android Development] asurabp:
Thanks, but upon flashing nameless I always got stuck on boot logo. Tried both p5 and p5wifi already, always stuck.
[Galaxy Tab 8.9 Android Development] jolinnard:
Sorry, but I don't know what happen with only that info.
[Galaxy Tab 8.9 Android Development] asurabp:
Went to twrp (im using in the op), wipe data, system and cache. Flashed nameless then gapps then wipe cache to make sure then reboot system. Then all i got is a samsung logo. Using a p5 btw. Tried both p5wifi and p5 versions, none works for me. Redownloaded the rom thrice so i made sure my copy is not corrupted tho.

Sent from my tomato
[Galaxy Tab 8.9 Android Development] jolinnard:
Ok, so the ROM doesn't boot. Can you try to flash last decatf's AOSP and see if it boots?

Don't know what is happening with p5 devices lately...
[Galaxy Tab 8.9 Android Development] asurabp:
Was able to work again with my tab. AOSP boots nicely. Also I solved the problem, after I flashed nameless I just also flashed figure kernel and it boots fine.
[Galaxy Tab 8.9 Android Development] hewhomustnotbenamed:
Need help i understanding which build of the ROM to flash?

Could you please let me know if 4.4.4 nameless is better or 13/5 lollipop build?

Which build do you advise to use with this old tab 8.9?

performance is my main concern..and if possible layers or theme engine (to make it look better)

request you to link the ROM as finding the correct build to download is a bit difficult here (I'm not sure which one is the latest and correct ) thanks
[Galaxy Tab 8.9 Android Development] jolinnard:
I'm using Lollipop AOSP by decatf. Here you have all ROMs: https://mirror.lnx.im/android/galaxy-tab/ROMs/Lollipop-AOSP/

I can't say what's the best (or the quicker) ROM. I'm on Lollipop since long time ago. It works enough fine to keep this device as video watcher, reader or email/communication device. You can't have a complete smooth experience with this device. It's almost impossible with all modern apps and games. But if you only need a device to do a small and specific use (those things I said for instance), the tab still does the job. One trick could be don't flash gapps, tab will fly :) (or at least with less apps running in background... so greenify is your friend :)
[Galaxy Tab 8.9 Android Development] hewhomustnotbenamed:
Thanks for the gapps one :D I will not flash them now and will sideload all the required apps

yepp..this can be used for video watching.. some browsing :)

I flashed cm11 primarily for the theme engine (I like themes :P )

Is there any way u could put together a cm ROM? hw wd u compare 4.4.4 and 5.1.1 in terms of performance battery?

I used ur 15 may build..it was gooooood :) but didn't have layers of theme bcz it is aosp ..

---------- Post added at 06:59 PM ---------- Previous post was at 06:55 PM ----------

people mentioned some problems in the latest 20150814 build.. so which build are u using?

thanks
[Galaxy Tab 8.9 Android Development] L3R0N:
You are right on this one....I've been on a no gapps and greenify combo and this thing really flies. P4 threads have been pretty quiet lately tho....Marshmallow maybe? Would be a dream come true if that happened.
[Galaxy Tab 8.9 Android Development] jolinnard:
I'm not planning to play with this tab in the next few days/weeks. Very busy trying M for my Nexus 4 and 9. But, maybe if people in p3 do something interesting we can port to our tab too :)

I've never post a ROM that cause problems for me. The major problem is with p5 devices, my p5wifi always works good. There is also a permanent issue with Samsung dock. My recomendation is that you can try by yourself. We have an old (but functional) TWRP, so backup/restore are your best friend :)
[Galaxy Tab 8.9 Android Development] L3R0N:
I can port just the ROM for you and use the previous kernel with it while you're gone. Uh I don't have time to build the latest kernel from decatf tho....

Meanwhile my N6 and N9 be enjoying Marshmallow...:silly:

Hi,

try to update a bit my wife's tablet and now :

• can't boot stuck @ samsung GT logo

• Can't mount with CWMR or TWRP from 1st thread

i m trying to flash a stock ICS usinf Odin but there is better way or speedest way ??

regards
[Galaxy Tab 8.9 Android Development] L3R0N:
P5 or P5wifi? You'll need to flash an older version of the kernel that's bundled with the ROM (its what I did to get mine to boot). I cant suggest a fike to you since i dont know which version of the tab u got so you'll have to find them yourself or reply with your tab version and someone should be able to point you to the needed file. Some users have no problems and others get stuck on the boot logo. You'll need to side load the zip to the tablet tho cause we don't have mtp functions in our twrp. Good luck.
[Galaxy Tab 8.9 Android Development] lesscro:
Thx for feedback... i use lastest build from OP... use original TWRP 2.7.1.0 recovery...

P7310 Wifi > flash AOSP > Gapps > SUperSU > Xposed

Now works like a charm... waiting about battery drain...

Regards
[Galaxy Tab 8.9 Android Development] L3R0N:
The build in the OP is not the latest version. The latest version is 20150814 which can be found here. Seeing that you had problems with the kernel that's bundled with it then you can flash v17 which can be found here. If it gives you problems as well then v16 could solve them and it can be found here.

Happy flashing!!

L3R0N
[Galaxy Tab 8.9 Android Development] lesscro:
Hi,

thx for reply. i know that build on OP is not directly the last but boot like Omni (but issue with wifi)....

Build on OP seems work, only stuff give me strange effect is internet speed... seems very very long to make something, my wife download an app on playstore, 15 minutes for 47,5 mo...

Can i dirty flash last build (already have it) over build from OP or need clean install ?

I suppose i can because i come from same ROM then not needed to wipe somthing...

Regards

Edit / Can't flash any of your kernel... always "updater binary error" 17 test 3 and 16

and real latest build can't boot...

Can i edit like "zip attack" lastest build with boot img and extra config in rom zip or it include MD5 check ?
[Galaxy Tab 8.9 Android Development] jolinnard:
Hey, I was lost in M world... Sorry about the outdated OP. I will try to update. Do you still have any issue?
[Galaxy Tab 8.9 Android Development] lesscro:
Still can't flash kernel v17 then can't boot into last build... anyway my wife's tablet run good !

Cheers
[Galaxy Tab 8.9 Android Development] L3R0N:
Can you at least post a recovery log so we can see why it fails? Anyway you can replace the boot.img in the ROM zip with the one from the v17 kernel zip. Be sure to copy and replace system/lib/modules in the ROM zip with the ones from the kernel zip to ensure things like WiFi work. If you don't want to do that then post a recovery log here so we can look at it and fix whatever the error is.
[Galaxy Tab 8.9 Android Development] lesscro:
Thx for tips... i m fresh with those manips then don't worry no trouble here !!

Will send feedback later, my go out with table.. i willl prepare zip for flash mania !!

Anyway, i will post a log to help a bit !!

Ok but how I can copy to the tablet because I just enter in recovery and PC don't see tablet like external memory?
[Galaxy Tab 8.9 Android Development] lesscro:
CWMR or TWRP for me does not mount device as MTP on my W10...

I have flash original ROM via ODIN to restore a working version, copy all files in internal memory then flash TWRP (sorry this recovery is just perfect) then finally flash desired rom, gapps (open gapps for me) and SU 2.46 and XPosed !!
[Galaxy Tab 8.9 Android Development] L3R0N:
You can copy files to the device via adb with this command

adb push filename.zip sdcard

Or you can side load the ROM to your device. First in TWRP tap on advanced and tap adb sideload. Connect your tablet to your computer if its not already connected. Use this command to send the file over

adb sideload filename.zip

The ROM will be sent to your tablet and will automatically install once its done copying.

Regards,

L3R0N
[Galaxy Tab 8.9 Android Development] steno66:
I tried your method, installed original ROM, installed TWRP and reflash your version of ROM but the result is the same.
[Galaxy Tab 8.9 Android Development] steno66:
Thanks, but I have still error: executing updater binary in zip.....namerom

Hey guys just here to upload the latest ROM from decatf. I,m not taking over this thread I'm just helping out while [MENTION=2002216]jolinnard[/MENTION] is busy elsewhere. This uses v17 of [MENTION=2002216]jolinnard[/MENTION]s kernel and not v18 since so many have issues with that version and v17 seems less problematic. I've modded systemUI to remove the full screen album art for playing music. Also I've changed the size of the expanded status bar (see attached screenshots) cause imo it looks better and the toggles are easier to press. If you don't like it then attached is the unmodded systemUI. Use rootexplorer to push it to system/Priv-App/systemUI and set permissions to rw-r-r.

Heres the ROm : aosp-5.1.1-p5wifi-20151012
[Galaxy Tab 8.9 Android Development] lesscro:
This One uploaded solve issue with v18 kernel... The only things made ont this zip is to integrate boot.img and associated system/files...

I did but the problem still randomly happens. Battery works fine one time and the other it doesn't. Gonna try finding a replacement battery over the weekend to see if it fixes anything.
[Galaxy Tab 8.9 Android Development] lesscro:
i think you already made this but did u recalibrate battery ? did you check battery consumption graphic ?

Kernel issue or build issue !

My advice begin by change kernel and try to discharge tablet and make a full charge then try again, if persist change ROM !

Flashed back to stock and battery seems to be fine for now. Gonna leave it that way for a few days to see how it holds up and then will reflash lollipop.

Tab ROM damaged by updates

I have been using the Rom from this post a long time. Last night I got updates from playstore, I think the playstore was updated as well. Tab rebooted unexpectedly and started optimizing apps (151)

This morning same routine, I tried to boot into recovery but can't anymore. And when booting it gives the loadscreen like forever.

Had one succesfull boot, then it says, trying to start app and it hangs.

I am back in download mode, going to try install Stock and work my way from there.

Main question for this thread, had anyone else had this happen to him/her in the past. I have never seen my tab this messed up.

-----update----

After reinstalling stock twice, wiping three times, I finally got my tablet up and running again.

Hope it keeps working now.
