Re-partitioning necessary?

Hello all.

First of all - BIG thank to developers for a port on to P7500. Tablet feels much faster and snappier now with aosp-5.1.1-p4-20150729

I gave it a try last time some month ago and it was much more buggier, rolled back to CM. But now it just works. Great!

As I read, apps in v.5 take more space comparing to v.4. Would it make sense to increase system partition?

If yes, is Odin + customized pit file is the only way? Who could create such file with, let's say 2GB system partition? I really don't mind having smaller data area, but want to avoid space issues in system.

My partitions now, after full wipe/install:

Cache:

total - 440.95MB

used - 7.5MB

Efs:

total - 11.80MB

used - 8.14MB

Data:

total - 12715.62MB

used - 1862.17MB

System:

total - 568.89MB

used - 490.57MB (86% !!!)

Thank you and have a nice day.

Lollipop 5.1.1 on Tab 10.1 / 3G

Hi

I tested all 3 ROM's and everything I tested works so far. :o

Everything except 3G. It asks me to insert the SIM card, but it is still inserted.

Would be great if you have any idea.

Note:

I'm not an expert. I followed the installation guide.

Currently I installed

- twrp2870-20150814-p4wifi.tar.md5

- aosp-5.1.1-p4tmo-20150814.zip

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

I see you flashed the p4wifi version of twrp. Does it make any difference if you flash the p4tmo version?
[Galaxy Tab 10.1 Android Development] klorgfasder:
Hi sherpya,

Thank you for that! I can confirm that the sim card is recognized on my p7501 and internet connection is working (H, 3G, ...).

Cheers,

Klorgfaser

PS: On a side note, my APN list was completely empty (already so with build 20150729), so no data connection; I had to create it manually (copied the info from the phone) and got connection. K.

Flash p4tmp to get 3G

Hi

I flashed "p4tmp" this morning and there is no difference. Android is not detecting the SIM card.

It appears a note on the upper left site of the screen "No SIM card - No Service" (in German "Keine SIM Karte - Kein Dienst")

I also tried to take the SIM card out of the Slot and placed it in afterwards. Still no SIM card detected.

Any more help would be appreciated.

Installation of "p4-20150814-radiofix.zip" did solve the problem.

Great job. Thanks for helping out.

APN?

Hallo Stoger.

Did you manually entered APN etc as klorgfasder wrote?

It helped me with aosp-5.1.1-p4-20150729
[Galaxy Tab 10.1 Android Development] Stoger:
3G connectivity Lollipop 5.1.1 for GT-P7500

Thanks for your comment.

I tried to add an APN, but there are 2 reasons I'm not able to finish that.

1. activating/deactivation APN in APN settings is always disabled

2. APN is asking for a provider password, which I don't know

Afterwards I changed language in my TAB to US-English. And that was the magic thing.

Afterwards everything was working perfect. (I knew that German is a difficult language, but for TAB's a ell ?)

Thank all of you for your immediately help. Great forum.
[Galaxy Tab 10.1 Android Development] ep3k20a03:
Yea. I just did a full wipe. Installed p4wifi-20141120, reboot, flash GApps, then SuperSU BETA-2.27, and reboot. When I launch SuperSU I get a message saying that there is no SU binary installed. I used the same flash method but flashed BETA-2.25 on p4wifi-20141114 and was able to retain root. Gonna see if I can find a working root method. Doh.....
[Galaxy Tab 10.1 Android Development] Dr asphalt:
Because most of of people have dame issue to install new upgrade i've extract only same app from system like browesr.

Now browser work well except sometime colse itself while i click to download from a link....but i don't know if it is only my random freeze.

By the way, when i open the new file update i' ve see that there are many directory duplicated with different date is it normal or can give same problem during the installation?

Another things, why the DPI is set to 160?? Is it becouse with the original Tab settings became to large or because is not yet optimized.
[Galaxy Tab 10.1 Android Development] cmwoody:
I had the same problem.

SU wouldn't re-root the P4, giving the lost binary error.

Used the 10.1 Odin tool to re-install twrp, did full wipe after then re-installed 5.0 and g-apps. Super SU hooked after bootup no problems.

Thanks to the OP, this makes this old tab new again.
[Galaxy Tab 10.1 Android Development] ep3k20a03:
Can you please direct me to which 10.1 Odin tool you are referring too? Thank you!
[Galaxy Tab 10.1 Android Development] cmwoody:
Specific for galaxy tab 10.1. Cannot post link because I have too few posts here. System won't let me. I'll pm it to you.

Make sure you have GApps and 5.0 Lollipop files on page one located in the P4's memory

Extract and run Odin in the file.

Turn on P4 in Download mode, plug into pc.

Wait for drivers to load and install. One or both d/l from windows so you may need to be connected to the internet.

When Odin lights up and says, "Added", press the PDA button and load the .tar from the file (either wifi or cdma version)

Press start, P4 will reboot.

Boot to TWRP, Wipe Cache, etc...

Install 5.0 and GApps

Boots up hopefully as mine did and works great.

Install SuperSU
[Galaxy Tab 10.1 Android Development] decatf:
Yes, SuperSU is broken on 20141120. I was trying to integrate Koush Superuser into this ROM a couple days ago without any success. But something has gone wrong since SuperSU is also now not working. I'm going to run a completely clean build again.
[Galaxy Tab 10.1 Android Development] ep3k20a03:

Touchscreen non-responsive in certain boot conditions

LOVE the ROM. It is very smooth, the smoothest I've seen in a long time.

Run into one issue. If I boot the tablet (on the 1114 version) while it is plugged into the charger OR my bluetooth keyboard is on and in range, the touchscreen is completely non-responsive when it finishes the boot. If I turn off my bluetooth keyboard and do not connect the charger, it will boot and everything is fine.

Hello [MENTION=4404851]decatf[/MENTION]

awesome work here. I'm trying to port Lollipop to p5wifi. I started to port your ROM (it was easy, but unfortunately in p5 we need to rotate the screen and the old code is gone) but I want to modify some stuff. Can you post all your sources (manifest, kernel...)? I saw your github, but I'm a bit confused how you are building this ROM, which sources are you using etc.

Thank you!
[Galaxy Tab 10.1 Android Development] Kazryu:
Please help, for some reason when i connected my p4 to pc win 8

It doesnt recognize it, there's a beep sound when im connecting it

And after a few minutes it comes out but i cant copy the file or whatever it is

It just keep disappearing from my explorer

Any solution about this? Will appreciate it! :fingers-crossed:
[Galaxy Tab 10.1 Android Development] decatf:
SuperSU should be working again in 20141122 build. It took longer to do because my computer bluescreened mid build causing the Ubuntu VM to get corrupted. The only additional change is a work around so microphone recording will work.

Current changelog: -- November 22, 2014

[fixed] SuperSU daemon not running

[fixed] Include a work around to enable microphone recording

The charger causing a power on is a bug. It's not any Lollipop feature that I know of. I'm still investigating the issue.
[Galaxy Tab 10.1 Android Development] jaibar:
First, many many and lots of thanks for your work!

I had this charger booting device "feature" on two different devices (HTC glacier and some LG optimus), and in both cases it turned out to be a kernel problem, if I remember correctly (was eons ago).

---------- Post added at 09:24 ---------- Previous post was at 08:54 ----------

[Q] Can the latest version (nov22) be dirty flashed over previous build, followed by supersu 2.16?

[EDIT] Had to reflash both gapps and SuperSu. No biggie, although all the widgets and shortcuts that I've previously added were gone.

Multi user seems to work fine [emoji3]
[Galaxy Tab 10.1 Android Development] Dr asphalt:
Thanks for new update. Works well.

I ve install over the Old without a wipe...only reinstall the superuser and than gaps.

All go like the "decatf" ad said

Black screen on unlock

First off Big up to decatf for compiling such great Rom so quickly for our ageing plucky wee GT 10.1 tab :highfive:, it just refused to go quietly, and to all the hard working talented guys/gals here at xda developers, amazingly talented group of people ;).

Now to business, out-with list of reported issues, anyone else having black screen issues when trying to unlock the tab with this rom?, reading through posts and haven't seen anyone else mention it so far, came from nameless kk 4.4.4 and also tried omnirom kk 4.4.4, never had this issue before flashing this rom, did a full wipe each time, but has occured on every build of this rom for me, unfortunately I cant grab a log when it happens cause screen won't come back on, having to holding power button 20-30 secs to reset it.

I know this is not a hardware issue, and googling it, it always seems to be a rom specific issue. not high on the list of current bugs granted, more irritating than anything, a but anybody else having this issue?, any help or suggestions greatly appreciated.
[Galaxy Tab 10.1 Android Development] decatf:
Thanks for the heads up. I've been looking in the kernel and the Android frameworks code. It turns out there is a new feature in Lollipop to boot from charger but it is not enabled by default. It is only for one specific device at the moment. I reverted the code anyways but the problem still exists. So the issue lies deeper some where.

AOSP does not have any feature for backing things up during a dirty flash. That comes from scripts added by custom ROMs. So that means it's necessary to reinstall gapps and root after a dirty flash.
[Galaxy Tab 10.1 Android Development] Nash123:
Installed it today on my Wifi-tab. Works great. Thanks! :)
[Galaxy Tab 10.1 Android Development] klorgfasder:
That drove me crazy for a while, too - until I realized that that option is disabled as long as the new APN is not saved. So I entered the info, chose 'Save` from the top right menu and then was able to select that single APN in the list...

PS: Never got aked for a password, though.

PPS: Was all in German, too; provider was o2
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Something I noticed since the 20150814 update is, that quite a number of tools no longer can see or tally background and system processes. They all report zero processes to clean up in the background. Has any additional security items been added to disallow cross-process information flow? I did skip the previous release, but I could not find any applicable info in both sets of release notes.

Is it just me, or do other users of your perfect ports notice this non-important 'feature change'?

By-the-way: this last 20150814 release is much smoother in graphical processing on games. Still have to do some benchmarking, tho'...
[Galaxy Tab 10.1 Android Development] FCKöln:
It seems i am getting closer to it. I found this change while going through the commit logs and copied the missing sec_keyboard binary to /system/bin/ on my device and started it with "./sec_keyboard /dev/ttyS0 &", plugged the tablet in to the keyboard dock... et voila.. keyboard is working :D

EDIT: Some additional changes to startup sec_keyboard on boot and some discussion about sleep/reboot issues with sec_keyboard
[Galaxy Tab 10.1 Android Development] DoktorImEinsatz:
Does not boot

I'm coming from CyanogenMod. I wanted to have a new Android on the system. So I installed like specified:

I downloaded

twrp2870-20150814-p4wifi.zip

aosp-5.1.1-p4wifi-20150814.zip

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

UPDATE-SuperSU-v2.46.zip

Then I performed:

flash TWRP

reboot into new TWRP

perform Factory Reset

wipe Cache and System

install the ROM

install gapps

install SuperSU

reboot into the ROM

I even created appropriate MD5 files. MD5 verification in TWRP was ok. But the system does not boot. It is stuck at the Samsung boot screen. I already flashed several times. At first I used the tmo version. Since then I learned that it is meant for T-Mobile. I hope this is correct.

Is there anything I can do/try?

Thanks!

UPDATE: I was not aware of the difference between the versions (tmo, wifi, bare). But now I think I need the normal ROM. So I once again flashed TWRP and ROM without 'wifi' in the name. But still no success. What am I doing wrong?
[Galaxy Tab 10.1 Android Development] Olivier V:
Perhaps you should be sure which tab you have. Is it wifi only, does it have a Sim slot? Wifi only is the 7510 or p4wifi. Sim slot means you have the 7500 or p4. The p4tmo was only sold in the USA if I'm not mistaken.
[Galaxy Tab 10.1 Android Development] DoktorImEinsatz:
I am sure I have the P7500 aka p4. But I did not know which ROM file I had to use for the device. There is no mapping device id to ROM file on the start page. But now I know...

In the meantime I tried to flash Omni 5.1.1. The symptom is the same: I'm stuck at the boot logo. I even installed CWM and restored an old backup. But it's still the same: The P7500 is stuck at the boot logo. So: any hints?
[Galaxy Tab 10.1 Android Development] TvBIFI:
did you get any errors during flashing ?

on my 7501 i´ve flashed first the twrp for P4 not wifi or P4tmo.

then i´ve flashed the P4 image.

after that wipe and factory reset.

then i took about 2- 5 minutes for the first boot.
[Galaxy Tab 10.1 Android Development] DoktorImEinsatz:
No. But in the file explorer of TWRP is saw that in some directories the directory '..' was missing. This led me in the right direction: The filesystem /data was corrupt. So I tried to repair it. But TWRP was not successful. Finally I formatted data, restarted the tablet – and I got the boot animation!

I am so glad the system works again. Thanks for your help! And for the record: A soft brick might be caused by a corrupt filesystem on /data.

p4-20150814-radiofix.zip needed for SIM detection

I'm late to this thread but thanks for posting the p4-20150814-radiofix.zip, sherpya. I have a 7500 on a UK carrier. 3G fails with no SIM detected. I can't get the SIM to work on this ROM without this radiofix.zip.

I did erase & reinstall the ROM, restored to stock, tried the p4, p4tmo and wifi TWRP versions in the first post & none would support the SIM. If you need logs I can revert & try to get some, but I couldn't get anything to crash of relating to the SIM/3G. It seems like you know what is going on, but I can test just tell me what info is useful.

Also thanks decatf & the other contributors, It's nice to refresh this Tablet with another OS.

[Galaxy Tab 10.1 Android Development] God_King_Nation:
Amazing work! Are you going to implement this into the new version decatf? I really need the keyboard dock working. Also, great job on the rom. Unbelievable that lollipop is faster than stock honeycomb. I also have two questions about the video driver. Isn't it possible to get proper drivers from a device with the same hardware? Not sure if even possible but it's just an idea, how do you guys live with those last videos? On regular video players like MX player or can play 480p video without lagging, but on YouTube only at 360p and lower does it not lag. Still great rom for a 4year old device !
[Galaxy Tab 10.1 Android Development] Nazdreg:

[Galaxy Tab 10.1 Android Development] stkt2ya:
Works great!

This is my first post although I have been creeping these pages for a couple of years now, I just figured I'd read and would no doubt eventually find the right answer somewhere... So technically I'm not a noob per say, I'm more like a veteran beginner...

Anyway, I essentially went with the install instructions although I initially took a couple other alternate routes to get there (Only thing I was confused about at first was the install TWRP first step, I originally thought that meant the Play Store app. It didn't). Nonetheless it still worked, that is until I screwed it up trying some different video settings in D/O, I was trying to get a game I like to play, Maritime Kingdom, running on this thing, thus far I haven't been able to, and this ultimately appears to be no exception.

After a few hours trying to repair my 'in over my head' mess I just went back and started from the beginning, as instructed on the first page. It works like a charm and took less than 10 minutes, I was even able to have Google restore all my apps for me so I'm happy to not be doing that.

I instead figured I'd come on here and thank decatf and all the others whom have pitched in here and there to lend guidance. Good job and keep up the good work! I'm stoked to be out of that lame-azz, bloated, Rogers infested ICS.

GT-P7500r

[Galaxy Tab 10.1 Android Development] mikep666:
Hi

First a big well done to decatf a I have also resurected a dying gt-p7500 - All works well except no GPS and no SIM detected.

Roms Used

aosp-5.1.1-p4-20150814.zip

p75xx-gapps-L-5-6-15.zip

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

Added

p4-20150814-radiofix.zip

Adding the radio fix fixed the SIM detection and GPS started working

The only glitch I have seen so far is that the gapps caledar app refuses to sync calendars and behaves strangely, asking for an account then claiming it is allready registered, which it is ie My Google accounr !. Gave up and loaded Google Calendar from play store and all is usesabel

Performance is good (as good as the original Samsung Stoke Honecomb and and ICS also mush faster than CM10 JB

Widevine DRM question

Hi,

many thanks to for this ROM, it is really awesome on my p4. I have a question concerning Widevine DRM. I'm trying to use the MagineTV app (for TV live streaming from magine.com). When I try to start a stream, it tells me that the Widevine DRM libs are missing. The app works on previous Android version (I checked with Kitkat and JellyBean ROMs), so I tried to check if the Widevine files are in the correct locations. When I move

/system/vendor/libwvdrm_L3.so

/system/vendor/libwvm.so

/system/vendor/mediadrm/libwvdrmengine.so

in this ROM (aosp-5.1.1-p4-20150814) to

/system/vendor/lib/libwvdrm_L3.so

/system/vendor/lib/libwvm.so

/system/vendor/lib/mediadrm/libwvdrmengine.so

then MagineTV does not complain about missing Widevine libs but tells me that "An error has occurred." (so, I guess, it detects Widevine now but something still goes wrong) and in logcat I can find the following messages related to Widevine:

E/WVCdm ( 156): App set unknown byte array property securityLevel
E/MediaDrm-JNI( 3342): Illegal state exception: Failed to get property: Unsupported scheme or data format (-2006)

Any ideas if/how this can be fixed? Or is it not possible to use Widevine on p4 with Lollipop?

Many thanks,

[Galaxy Tab 10.1 Android Development] God_King_Nation:
Heya [MENTION=4404851]decatf[/MENTION], I'm having some trouble connecting to a wifi network.

The wifi network I want to connect to is the school network. It is a hidden network so I tap add network, choose 802.1x, and then the name of the network.

EAP method is PEAP, no Phase 2 authentication and CA certificate is (unspecified).

My Identity is my pupil number and my password is my pupil password. I am 100% sure that I filled everything in correctly.

Even though I do this, the network won't even show up in the list of scanned wifi networks or connect to it.

My phone is running Cyanogenmod 11 Kitkat 4.4.3 from here. I did the exact same steps and on my phone, and it connected on my phone.

- I know I can use the same pupil number on different devices, as a classmate has shown me, so that's not the problem.

- I tried using Hidden SSID enabler, but that didn't work.

I think this ROM doesn't have a certain wifi certificate, but I'm not sure how to check which one my phone is using for the network, or how to install that certificate on this tablet.

If anyone can help me please post!

Thanks in advance !

Edit: Solved by switching advanced settings on and off and not usig a keyboard with autocorrect.
