Some people reported slow charging, switched to temporary to AOSP charger which doesn't have percentage view. Hope it charges faster now.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] DrTron:
Hi Guys,

I'm currently trying to revive an old Tab2 with a fresh OS. However, I seem to be stuck at installing the recovery. It's currently running TWRP 3.0.0.3, and I'm trying to update it to the recommended 3.2.0.0. Odin3 flashes the new TWRP fine and without errors, but booting into it shows it still runs the old one.

I tried:

- using different Odin versions - no avail.

- running fastboot from command line - tab is not detected.

- adb detects the tab in recovery, though, so the cable and connection work.

Any ideas?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CRNair:
If you are on TWRP 3.0.0.3, just download TWRP 3.2 zip version and flash it from recovery.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Android-Andi:
Could be the legend emmc brick if Odin can't update the recovery even if it shows it was successfully flashed
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] guest4711:
[MENTION=4444344]DrTron[/MENTION]: You could verify the emmc brick by deleting a file in TWRP (using filemanager or console/terminal). If the file is gone after reboot, you don't suffer on the emmc brick. If it's still there, the emmc is read-only - no chance to do anything before changing the motherboard or repairing the board...
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] DrTron:
Wow, you guys are really good (and dead-on). Thanks for all the input!

It really seems to be emmc-bricked. Files deleted in TWRP show up again after a reboot.

I admit that I already had my suspicions about a hardware error as the device (used as a weather station) worked flawlessly (though slow) through more than a year, and suddenly failed. So a software issue was not really to be expected.

I guess I'll go and look for a used tablet then.

Guys, i full wiped and installed the newest file.

Whats the best gapps for this, i used open_gapps-arm-7.1 micro from 20180128

But for some reason it keeps really laggy, any idea?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] john99ap:
Try pico version. If it continues to be laggy, don't flash any gapps at all.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] guest4711:
Have a look at the running processes - which one is eating your cpu?

You may use "top" in the terminal for this purpose or an app like OS Monitor (Monitor the Operating System) - https://f-droid.org/app/com.eolwral.osmonitor -.

Dock not working.

Hi

Tried a lot of versions and came by your version "lineage-14.1_espressowifi-7.1.2-20180131-1818.zip" and it work perfect except the docking function. When I set the P3110 in to dock I get the dock sound in the speakers in the device but the sound is never directed to the dock output connector, instead the sound comes out of TAB 2 (P3110). I have not found a version since a 4.4.4 CM version that worked, everything out there since does not work. I was hoping that you could take a look at it once for all. I know that it must be a bug in the driver somewhere but a compere with and old 4.4.4 should reveal the problem. I am a software engineer my self and if there is any thing I can do to help find the bug please let me know. I have not tried to build a kernel "yet" but I have thought about it lots of times. :cowboy:
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] 5m4r7ph0n36uru:
[SPOON FEEDING]

RULE NO. 1: USE THE THREAD SEARCH!

Dock isn't working and won't work on all version starting with at least LineageOS 13. This is due to the drivers that can't be proted to the higher base. If you are able to find a way porting them, let Andi know of it and he'll for sure integrate your port.

In a 3G version the demon is needed for the tablet to work properly on 3G, and may cause high loads on the CPU.

First, I would like to thank you for bringing new android to this old tablet.

Second, I have problem with playing videos from youtube, SD (via MX player) and Netflix. Its freezening, audio is playing but video is stopped and these kind of problems

Anyone have problems with playing videos ? I am not sure if this is not related to old GPU and chip and therefore it is something what cannot be fixed by ROM/SW/App....

I am using build from 31st of January 2018. for Samsung P5110

First of all, thanks for creating this ROM. I have installed it on my p3110 expressowifi and it functions well.

I understand, that dock isn't working due to incompatible drivers. I don't need the docking functionality, but I'd like to use the dock as charging stand. But if I plug the tablet into the dock, it is hanging like on LOS 13 where an irq/162-accesso blocked the CPU. Any ideas for workaround?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] mentat:
Greetings,

This is a very interesting idea... simply blocking, disabling or ignoring the media functions of the dock (with the exception of the charging function) in the ROM (or kernel).

I wonder, if this can be achieved through "boot time" or startup configuration files or parameters, so that is not necessary to re-compile the ROM (or kernel)?

Also, I read an interesting post from [MENTION=1540649]thekwijibo[/MENTION] (https://xdaforums.com/showpost.php?p=75582121&postcount=4) suggesting a hardware modification to the dock itself to disable all functions (with the exception of the charging function).

I wiped the dust of my EDD-D100BE (desktop dock) for a closer look, but have not (yet) found a way to open it (without destroying it) to investigate the hardware modification option.

Thanks.

Sometimes error 7 is appearing during Flash but rebooting to twrp a second time makes me able to flash this Rom but then.... the old Rom is booting ?

Also an update via twrp 3.2 to 3.2.1 flashing the image file to recovery does not work, rebooting is allways 3.2 and not 3.2.1 despite the flash seems to function via message from twrp 3.2...

To i have a emmc Problem? erasing a file from the internal sd does work...

i can boot the actual installed Rom but it is randomly rebooting at the start up soi can not use the tab...

Also saving back an old nandroid brings me always to a random reboot at the end of the backup from twrp and starting the old Ron?

However I don't know why and also see if there's nothing blocking your mic try removing your cover.

2. Try downgrading, do a full wipe and then install, clean install.

interesting answer for me. This build here were stable for about nearly eleven days on my tab 2 3110, daily hard use :) . And when it lags sometimes after a restart, i only restart into download mode, switch it off, an restart normal mode again - it seems to work.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] bluesaka111:
well no. If you have root manager installed, you must allow system processes / app to gain access to root and allow root during bootup or it will be extremely lag.

All the roms I tested AICP / Slimsrom / Omni / Stock 4.1.2 have this problem.

With all roms you should:

Only flash the Gplay bare minimum package and install root right after this (no wipe dalvik / cache between package install if you sideload them but you must manually wipe dalvik / cache before reboot into system).

Complete the setup wizard without internet connection will allow you pass through the setup wizard nearly rightaway (no setupwizard force close message) and you can turn on internet connection right after you complete the setup.

Check "Trust system user" in your root manager of choice and you will never encounter any performance hiccup during intense use or after reboot.

If you use SuperSU from chainfire, check "Enable Pro" if you are planning to use it on stock rom (TouchWiz) & TriangleAway.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] :
Undoubtedly the best up-to-date ROM here. Great work sir! Far much smoother than any other nought ROM. Just one bug, the recents screen shows the apps like this : (see the attached photo)

Edit : I just read this thread, and found many of you are facing lags. I faced them too. But now, I found some solutions and they really helped. No lag at all. I can play max payne at max graphics with no lags or frame drops. And yeah it also matter which GApps you use, I recommended beans GApps mini package.

How to fix lag?

1. Search google for 'ABS Tweaks'. Go to the xda thread and proceed as the instruction by the OP.

2. Search play store for 'fstrim' and install the app. Just set the automation timer for weeklies!

(UPDATE)

3. Search play store for 'Root Booster', download the app, set the mode to stable(stock) and enjoy. This app is so brilliant that made me to spend ₹62(0.99$) to unlock the pro feature, I highly recommend this method if you really want stability. Stock mode also works fine BTW.

Ta-da you have a galaxy tab 2 completely lag free.

Edit #2 : Just read the thread even further and found GApps related problems, such as

1. Setup wizard has stopped.

2. Beans GApps causing lags.

These are discussed below...

1. Well, setup wizard crash is an android 7.1.x problem, occurred with me with every nougat ROM.

- My solution : After flashing ROM and doing reboot to setup your tablet. Rather than setting it up, just connect it to the charger and leave it aside for 10 minutes and then setup.

- Reason behind this problem : This seems an internal issue in the master source code, as it occurs in many moto and Samsung devices. The device is unable to grant required permissions i.e. storage and telephone to the setup wizard. Giving sometime to the device allow it to set up the permissions.

2. Lags, well, all of us know that many of the tab 2 users(including me too, I am sorry) demanded the master dev(@Android-Andi) to release nougat ROMS, even with the known problems existing... There is no permanent solution however, the methods listed by me at the staring of this reply can really help. I have tried almost all of the GApps(including Beans GApps , slim zero GApps, open GApps, A-GApps and banks) but found Beans GApps the most reliable, but I suggest you should try all of them. I am listing the GApps, as per their features :

1. Stable, Daily use and feature full : Beans and Banks GApps

2. Minimal and performance : Slim Zero Revisited, A-GApps

Well, I think I have wrote a whole guide, LOL, but since this was necessary so I gave it my time. I may update it even further if I find other options.

Thank you,

KG
