You can dirty flash.
[Galaxy Tab 10.1 Android Development] liter1:
Amazing rom! I'm impressed of the speed and no bugs were found (for now :eek:)
[Galaxy Tab 10.1 Android Development] animusFL:
ok , I can't get the last build 20150127 to keep root, dirty or clean install. No SuperSU binary and SuperUser is installed?? Wazzup?
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
You need to download and install the latest and greatest zip-file of Supersu with TWRP after installing ROM and gapps (see first post for links)
[Galaxy Tab 10.1 Android Development] fase77:
This ROM is awesome :good:

Any way to delete the extra empty screens? Also, was anyone able to use 3g, SMS and phone calls?

Thanks, I really appreciate the hard work by the developers and contributors :)
[Galaxy Tab 10.1 Android Development] aduhai:
You can use 3g , SMS but not a phone call.
[Galaxy Tab 10.1 Android Development] honhan0904:
For extra emty screen, use nova launcher

3g sms work find

Phone call? Buy a phone bro
[Galaxy Tab 10.1 Android Development] fase77:
I don't want extra screens, I want to get rid of the extra ones. I'll try nova launcher though, thanks.
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Nova Launcher allows you to delete the screens, similar to stock method. You modify screens and drag empty ones to waste-icon centre top. You'll see when you do it. Love Nova Launcher...

Does anyone here get issue when flash zip build 31.1 p4

It got error

It say: set perm fail

Twrp 2.8.0.0
[Galaxy Tab 10.1 Android Development] fase77:
I'm testing it right now and so far it looks good. Anyone having slow app installation? They download fast but the install process takes at least 2-3 times longer than ICS!
[Galaxy Tab 10.1 Android Development] rahimskala:
Archive firmware has not been touched, I gave an error when I archive to firmware wanted to remove unnecessary.TWRP 2.8.3.0
[Galaxy Tab 10.1 Android Development] honhan0904:
[MENTION=745155]decal[/MENTION]f could you have a look on those zip.

Tried download 3 time and dont work o.o
[Galaxy Tab 10.1 Android Development] Prowler665:
The download is workin' fine, just tested it.

Have a look at the md5-hash of the file you downloaded. It is supposed to be 29e412e36acd4b0977cbffd128406d00 p4-lollipop-20150131.zip.

If you need a utility for windows just google "windows md5 hash"...

[Galaxy Tab 10.1 Android Development] honhan0904:
That strange

I have downloaded 3 times and it still say set perm fail

What i have to do now?
[Galaxy Tab 10.1 Android Development] animusFL:
Thanks, that did it. I didn't know there was a new version out.
[Galaxy Tab 10.1 Android Development] honhan0904:

Revert Fix On-Screen keyboard

[MENTION=4404851]decatf[/MENTION], been using this Rom since the first day it popped up on XDA, and am very grateful for the work you are putting into our device. Just a quick question, what was the reason for the revert:

Revert "WindowManagerService: Fix On-Screen keyboard popups when hw-keyboard is present"

In the build from the 27th of Jan and does this come back?
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Keyboard did not come up after sleep to unlock when using passwd. Default "soft" keyboard was disabled by default. So chicken and egg problem when upgrading.

[MENTION=4404851]decatf[/MENTION], First i have to say, Thanck You Very Much for your ward work !!:D:D

My Galaxy Tab 10.1 was on official release of 4.0.4 and now with this ROM is much faster !! On oficial in Antutu Benchmark i get 9490 points, and now i get 13570 points :fingers-crossed:

Is much faster and no lag, but i´m having some troubles with usb connection to my PC...

When i transfer files from windows to the Tab, sometimes i lost connection and the files doesn´t transfer to my tab :crying:
[Galaxy Tab 10.1 Android Development] honhan0904:
Delete
[Galaxy Tab 10.1 Android Development] eushaun99:
Probably a bad cable...try using another cable.
[Galaxy Tab 10.1 Android Development] Melo19:
With you transfering usb filies is working well ? If yes, then i will need a new cable..
[Galaxy Tab 10.1 Android Development] decatf:
I have that problem with USB connect dropping too. I don't know where the issue is. To prevent it from disconnecting, open the internal storage in a file manager on a computer. When the internal storage is opened on a PC then it will not disconnect.

It's annoying but there isn't much to go on. All I know is that it started happening where around when TWRP 2.8.0.0 was released. So some time back during the Kitkat days.
[Galaxy Tab 10.1 Android Development] eushaun99:
It was just something that popped into my head. Its been a long time since I transferred something via USB so not really sure tho. If you do have an extra cable lying around then it doesn't hurt to try it. But the problem should be what decatf said.
[Galaxy Tab 10.1 Android Development] ZeroDs111:
Hi, can help me? I have a 7500 Tablet, is not mine, is from my girlfriend, so the Tablet has Android 3.2 and i want to update it, Can you explain me how to do this? The Tablet doesnt have root , is pure stock.

Other question, The Bluetooth (Transfer files) Wifi (Connect to the network) Camera etc. works fine? She is not an advanced user

Thanks a lot :D
[Galaxy Tab 10.1 Android Development] Backe888:
Welome. This is not a thread to explain the first steps.

There are a lot of threads which explain what to do in detail. Read those first, and if after that you still have questions, post them in these threads.

We will be happy to help you then, but first you will have to do your homework, we cant do everything for you.

Search for threads that explain how to root, how to use Odin, and about firmware compatibility. Those are my hints.

There are also a lot of youtube videos that show things for beginners. They were very helpful to me at the beginning when i wasn`t sure about stuff.

And a last tip. Since you want everyting to work fine, stick to 4.4.4 versions("Nameless" is my preferred, "Omni" is good too). Android 5.0.2 is still missing a lot of features(for now) for this tablet .
[Galaxy Tab 10.1 Android Development] jaibar:
There are specific threads explaining how to root the tablet, just look for them.

However, are you sure you want to do this to your girlfriend's tablet?? If it is working fine and she is happy with it, and something goes wrong- Murphy's law and all that- you know the drill: guess who's gonna sleep on the sofa? [emoji14]

Seriously, going all the way from stock HC to rooting, installing recovery, maybe cm10/11 before going to LP is not rocket science, but lot of steps to go wrong. Samsung did it more complicated those days than new devices like nexus. Myself, I did it like two years ago and don't even remember which method, nor have I kept the required files.

And you say she is not an advanced user, she probably doesn't care about rooting, recoveries or has fingers twitching for flashing every time a new build is up. If she just uses it for casual things maybe best leaving device as is? Some features she is used to may not work or be buggy.

Good luck! [emoji1]

[MENTION=3599815]jaibar[/MENTION] [MENTION=4508654]Backe888[/MENTION] I really apreciate your answers, and you make me think in a very interesting point, maybe is better just upgrade to ICS with the Samsung stock firmware and nothing more, I will read the threads, thanks a lot for the ideas :D
[Galaxy Tab 10.1 Android Development] rsantiag:
Just installed on my P7500 ..

Hi all,

Just intalled on my p7500 and it looks like if i bought a new device!!! wow!! I was using the ICS Stock rom, which is BTW the worst rom I saw, and the change is incredible!!!

Excelent work!! Thanks!!
[Galaxy Tab 10.1 Android Development] murtok:
First of all, thanks for the amazing job so far. This ROM brought the old Tab 10.1 back to the present day.

Everything other works fine for me but bluetooth audio stops working after being connected, but not used, for some time (half an hour / hour) and the only cure I've found is to reboot the device. The other thing related to BT audio is that there are periodical silent gaps or connection glitches when playing in the interval of a few seconds. Both of these issues, or at least similar ones, have been already reported earlier in the posts #594 and #628.
[Galaxy Tab 10.1 Android Development] honhan0904:
This rom so amazing

I dont feel lag anymore

Thanks for your amazing work decaf

[Galaxy Tab 10.1 Android Development] Prowler665:
Noob-friendly guides part 665 - from stock to rock

Since most of it is written here already anyway, here are the missing parts...

Part I - Preparing HC

This will get you root and CWM on HC:

Download stuff needed

Latest Samsung-drivers

Odin

bootloader and recovery according to your device from here. For model 750x use p4, for 751x use p4wifi.

Vintage Superuser. This might work with a recent SuperSu too but I didn't test it.

Install the usb-drivers and make sure you can connect to the tab from your pc.

Boot the tab into download-mode while still connected to your pc.

Shutdown the tab.

Boot up the tab and hold down the power and volume-down keys until you see the two android icons.

Stay on the icon that has 'Downloading...' written on it and use the volume-up key to enter.

Use the volume-up key to confirm the warning. Wait while windows is installing the device-drivers if needed. If ready, there should be a message on your tab '==> Connected! ...'

Use Odin to flash the recovery. Do

NOT

touch the bootloader yet.

After starting Odin, there should be a com port listed under "ID:COM" and a Message saying "<ID:=/0xx> Added!!"

Make sure only "Auto Reboot" and "F. Reset Time" are checked.

Check PDA and select the recovery-file you downloaded earlier.

Hit the Start-button and wait for the tab to reboot.

Sit back and have a coffee, you're almost done with part I...

Place the Superuser-3.1.3-arm-signed.zip file on your tab and boot into your recovery (this should be CWM now).

Flash the superuser zip-file. Have a look at part II on how to do this.

This step is only needed if you want to make backups under HC using TitaniumBackup. You can omit it if you want to get rid of your user-apps anyway.. :eek:

Part II - Installing Lollipop.

Have a look here on how to do this.

The only additional thing you will have to do when coming from HC is flashing the bootloader. You can do this in Odin, simply make sure to tick Bootloader instead of PDA this time. Do this after you made your backups on HC / flashed the final rom and before you start LP for the first time.

On a p4 you might have to update the modem too. Flash using Odin as PDA if needed.

If you update your tab to ICS using Kies first you can omit updating the bootloader/modem, but you might lose your user-apps and settings since I don't recall if this includes a factory-reset :confused: It most probably will thou...

If you have problems with 3G on Lollipop, have a look here on how to setup an APN.

Nevertheless, if anything goes wrong big time you have a backup right?

And of course you are doin' all of this at your own risk ;)

Regards
[Galaxy Tab 10.1 Android Development] honhan0904:
Must install ics first for bootloader update

After that just followed Prowler665 instruction
[Galaxy Tab 10.1 Android Development] Prowler665:
How about readin' the post before quotin' :confused:

The guide is intended to be able to make backups using TitaniumBackup on HC first.

You wanna tell your spouse her favorite apps and highscores/bookmarks are gone? Good luck mate...

Any Solution to this?

Did you find any solution to this problem? If yes please help me. I have tried everything but this doesn't get solved. I am using CWM 6.0.4.6 on Samsung GT- I9300I. The installation gives status 6 error and the log says: "unknown function "block_image_update 1 parse errors"

Thank you.
[Galaxy Tab 10.1 Android Development] Olivier V:
Well, why are you trying to flash a ROM that is meant for a tablet on your galaxy S3 mobile phone? That's just asking for problems and it will never ever work.

Sent from my Z1 Compact
[Galaxy Tab 10.1 Android Development] L3R0N:
Hi [MENTION=4404851]decatf[/MENTION], would you mind adding in the rotation fix from Omni so that this ROM can work on the Tab 8.9? Its already added into AAccount's OmniROM and it works great. We (the Tab 8.9 Users) would be mighty grateful to you if you did.

Have a look here for the fix. Its a series of 6 Patch Sets. Looking forward to a response from you.

Regards,

L3R0N
[Galaxy Tab 10.1 Android Development] Pukat:

[Galaxy Tab 10.1 Android Development] gunner33333:
Some apps are designed for phones and cannot be downloaded onto wifi-only devices. If I install the p4 ROM on my p4wifi, will I be able to install these apps?

I've tried both the google play store and sideloading the apks and they don't work. Strangely, I used to have these apps in Omnirom 4.4.4 and in an earlier version of this Lollipop (no longer on the download list) and I have backups of them in Titanium, but they will not restore from the backups in this latest Lollipop. One of them is the NASA app and the other is Yik Yak (I know that's a really crappy app that I can certainly live without, but there may be others I might want in the future).

Anyone know a solution?
[Galaxy Tab 10.1 Android Development] eushaun99:
Exactly. Lucky it failed or else you would have a bricked phone.
[Galaxy Tab 10.1 Android Development] ZeroDs111:
Wooow thanks so much Guys you are really the best!!! Thanks a lot really :D

Ps. If i want to update to Kit Kat is the same right? just a KK Rom instead a LP rom?

Thanks again :D
[Galaxy Tab 10.1 Android Development] Haseeb-I9300I:
No No I am not flashing this ROM in my phone. I'm flashing the one made for my phone. I got the same error so I thought if he could offer any help.
[Galaxy Tab 10.1 Android Development] Olivier V:
Then it's better to ask your question in the right forum. Each device behaves differently and each custom ROM maker adds his own cherry picks from different places and therefore aosp for this tab isn't the same as aosp for the galaxy s3.
[Galaxy Tab 10.1 Android Development] Haseeb-I9300I:
Ok ! Thanks ! I have already posted the question there.
[Galaxy Tab 10.1 Android Development] 1stHTCphone:
First of all. Thank you very much for this excellent ROM. Awesome!!!

Question, I know that playing HD video will lag on our tab cuz outdated drivers. But now the video just freezes with sounds in the background. I tried the usual disable hw; force gpu; nupalyer..etc. with no luck. Any idea? At least in KK I could still watch choppy HD YouTube...LOL... Thank you!
[Galaxy Tab 10.1 Android Development] Prowler665:
The guide will work for everything from ICS to LP.

As soon as you have the ICS-bootloader/modem and TWRP installed on your tab, flashing any new ROM is easily done via TWRP only. The only exception is HC. You will have to flash an HC-stock rom via odin to downgrade the bootloader again.

As someone new to this do not, neverever, omit the (nandroid-)backups. They will let you return to a working device in no time if something goes wrong while tinkering around ;)

Regards
[Galaxy Tab 10.1 Android Development] eushaun99:
Change to 480p. Not HD but still quite clear for me.
[Galaxy Tab 10.1 Android Development] decatf:
I've added it. I don't have a build to post yet since there is some other changes which are causing problems that need to be straightened out.
[Galaxy Tab 10.1 Android Development] L3R0N:
Thanks. looking forward to your new build so I can test on my 8.9. :) :good:

Mount USB not working

Thank you so much for this ROM!

I do have an interesting problem that when I try to conned a USB flash drive to the tablet, it doesn't mount it. If I go to Settings -> Storage and try to mount the USB drive, it pops up "USB Device Removed". However if I use terminal emulator and mount the USB drive using "mount -t vfat /dev/block/sda1 /mnt/usbdrive" it does mount and I can see the contents of the flash drive. I can only see the contents through terminal emulator, File Explorer shows /mnt/usbdrive empty. Any ideas? Thanks in advance!
[Galaxy Tab 10.1 Android Development] stressor:
Can this ROM be apllied on GT P7501

First of all:

Thanks for your work.

I searched the Thread and didn't find a hint,

if this rom can be flashed on the GT P7501 (3G).

Really appreciate a short answer ;)

Thx

Sly
[Galaxy Tab 10.1 Android Development] decathlon:
I had the same problem.

Just install Stickmount app from the playstore and you should be good to go.

It worked for me. I think it is a measing feature in AOSP because if im not mistaken the Nexus 6 also has this problem.

---------- Post added at 03:24 PM ---------- Previous post was at 03:21 PM ----------

I also have the 3g version but my device model is P7500 (or P4 in the forum)

Are you sure that yours is P7500?
[Galaxy Tab 10.1 Android Development] honhan0904:
P7501 is german version

And it still can use p4 rom
[Galaxy Tab 10.1 Android Development] Prowler665:
The differences are only cosmetic to circumvent legal issues brought up by apple when the "iPad-killer" hit the market :D

Internally the GT-P7501 is identical to the GT-P7500 (p4). The same goes for the GT-P7510/7511 (p4wifi). Just make sure you don't have a 'Galaxy Tab 10.1 T-Mobile' (SGH-T989), that's a p4tmo and has to be build seperately.

one stupid question sry, is this rom not rooted?

stupid sry forget to install the UPDATE-SuperSU-v2.45.zip
[Galaxy Tab 10.1 Android Development] honhan0904:
When flash cook rom i always flash gapps and supersu after flash rom.

If you got problem about miss root, try flash update root again

Regard
[Galaxy Tab 10.1 Android Development] Prowler665:
No, this rom is not rooted by default. Have a look at the first page for a link to the latest SuperSu-zip.

...ooops, too slow ;)

Once you have installed GApps and SuperSu there is no need to flash them again when doing a 'dirty' flash. The GApps are taken care of by an backup-script provided by the ROM and SuperSu by it's own backup-script (if installed). Simply have a look at the SuperSu settings and look for 'Custom ROM'.

Regards
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Good Job!

Any reason not to build TWRP 2840? Seems it fixes a few bugs of 2830. Not complaining though. Is the new AOSP Launcher3 'better' than Nova Launcher?

Downloading as we speak, and will play around with both the rebuilt TWRP and ROM. Again many, many thanks for doing this ungrateful job over and over again and still (hopefully) have a good feeling about having all these people put new life in the old/ancient Mastodont called Galaxy Tab 10.1.

A job well done, Sir!
[Galaxy Tab 10.1 Android Development] kashortiexda:
[MENTION=4404851]decatf[/MENTION] are you presently running f2fs ? I have tried it on my Note2 and S3. So far f2fs on lollipop has caused a lot of grief for a lot of ROMs. Does the updater script cater for either ext4/f2fs install ?

Arter97 in S3 i9300 kernel/recovery has a very advanced f2fs implementation, using Samsung f2fs latest code... in case you are interested to explore
[Galaxy Tab 10.1 Android Development] decatf:
I am using it. What problems occur on other devices?

The F2FS in this kernel is backported from kernel 3.4. It is the latest version.

TWRP 2840 has been buggy. I'm waiting for them to fix up some things.

The launcher you use is up to you. I think Nova is probably faster than the stock AOSP launchers. I use the old AOSP launcher myself.
[Galaxy Tab 10.1 Android Development] kashortiexda:
Other users reported data loss (I never had this) I got several freezes and lags. Let me pm you some links so I don't clutter your thread.

Perhaps different sdcard, or poorly implemented.

I don't mean to detract users but just wanted to share my personal experience of f2fs with lollipop.

That said, your work is impeccable and you've probably nailed it.

Thanks for your work on this ROM, its amazing, new life for this old baby
[Galaxy Tab 10.1 Android Development] decatf:
Well F2FS is not my work. It's the work of Samsung and the kernel developers. And as I posted in the changelog the F2FS for this kernel is from the grouper kernel (aka Nexus 7 2012). Someone else backported it for kernel 3.1.10 which is the same kernel version as this device. So it is not much work to merge it in.

My real goal here is to get SELinux working. This kernel already had F2FS since it is a fork of twa_priv's kernel. But that old stuff related to F2FS was breaking SELinux. I was trying get that fixed and I figured I'd take the opportunity to use the latest version of F2FS since it is officially supported in Lollipop.
[Galaxy Tab 10.1 Android Development] honhan0904:
But when i flash this rom root still there but gapps gone

I have to re flash gapps everytime when update new build by decaf
[Galaxy Tab 10.1 Android Development] Prowler665:
Thats strange... I just updated build 20150131 to 20150208 by simply flashing the ROM. SuperSu as well as the GApps are still there, just like they should. I am still using TWRP 2.8.0.0 thou. I couldn't make up my mind to upgrade TWRP for now.

The first thing you should see when flashing a new ROM is "Running backuptool.sh" and towards the end of the process "Running backuptool.sh restore" ...thats when, among others, /system/addon.d/70-gapps.sh is executed.

This file takes care of backing up the GApps before installing the ROM and restoring them when done. Please check if the file exists on your tab and if there are any errors or messages regarding the backup while installing the ROM.

If the file is not provided by your GApps zip-file, or causing any trouble, consider using some other GApps. Independently of the ROM usually the GApps either provided or recomended by the OP work best.

To get a log of the flash-process in TWRP hit Advanced/Copy Log to SD before you reboot.
