[MENTION=8017516]Kunal Gautam[/MENTION]: Thanks for the hint. Using fstrim really speeds up the device, although I set my device to do the trim twice daily...

However, I wasn't able to get it running with beans gapps nor ABS Tweaks. I used TWRP 3.2.0-0 from the link provided as well as the deltadroid gapps base version. So far, my device is running smoothly - thanks a lot [MENTION=5153662]Android-Andi[/MENTION] for this awesome rom!

Hello,

yesterday i've read in the Oreo thread for the Galaxy S2 phone, that it is possible to switch between standard Android and low Ram version. Just read here:

https://xdaforums.com/android/software-hacking/mod-low-ram-property-patcher-android-t3737373

I'm testing Andis version now in low-Ram configuration. Hoping it can be usefull for other users.

------

Edit: same as before, after a restart it could be that it is lagging. I've made a bugreport, which parts are interesting?

In recovery i found out that, after having lags, i can't format cache partition - it said it wasn't mounted. When i try to mount it manually, the path was on D: SD Card. After putting it back on C: formatting works, ant the tab 2 was ok again. I'll check this when the problem occurs again.

Congratulations to those who cooked this ROM, it works great even if unofficial. But I noticed a small problem when I make a call with the active data network and also wi-fi. Let me explain better ... I happened that the call fell after a few seconds with the appearance of an error and the signal disappeared ... I restarted and then I removed the data connection and the call no longer fell. I then tried to make the call with active data network and wi-fi turned off, the call did not fall but the data connection was turned off by itself. Finally, and I think it depends on the same problem, I noticed that GSam battery detects excessive consumption by "mobile data" ... even greater than the kernel and the operating system. For the rest, the ROM is perfect considering the age of the tablet. Congratulations again for the job.

I just tried to make a call with the wi-fi enabled and the call drops after a few seconds

Hello everybody,

I'm just passing by here in my quest to update a Android tablet of a neighbour of mine, and see that you guys are experimenting with getting LineageOS 14.1 running smoothly on the Galaxy Tab 2.

First a small introduction of myself, my name is Jasper, I have been a LineageOS developer in the past for some time for eg. LG Optimus G and LG G2.

I see somebody is experimenting with the Low Ram option, this is definitely the way to go, seen the specs of this device.

How is it working out, need any assistance?

Also you could try make use of Zram. I've done that as well with LG G2, and even more modern devices (like Xiaomi Mi 5, which I own right now) make use of Zram by default.

Check: https://review.lineageos.org/#/c/LineageOS/android_device_lge_g2-common/+/19288/

Of course Zram needs to be enabled in kernel build, and maybe for this kernel needs some updating too.

Trouble with SU

Hi [MENTION=5153662]Android-Andi[/MENTION]

First of all, thank you for your great work above this 'old' device.

I have a little question about the SU package for gaining root access on my tab.

I have installad the Lineage OS 14.1 with Gapps package 'micro' on my GTP3110 (wifionly).

When i try to install the SU package on posted on the first page of this thread (for the version 14.1, sure) i've a problem: after the download of the zip file, i copy that on my tab, then restart in recovery for flashing it.

In the recovery, after selecting the file, it start to flash and after a while a receive the following message:

Opening update package...

Verifying update package...

E: footer is wrong

E: signature verificaion failed

Installation aborted.

I've tryed many solutions without success (downloading new one, tryed different package etc..).

Can someone help me getting rid of that issue?

Thank you!

Hi,

I tried this ROM and the AOSP and both are great!

Everything goes well until the first offline battery charge. After that, the tablet goes with lag, with the CPU always at 95%-100% all the time!

I tested a lot (with clean flash all the time) and it´s a real strange thing, but it´s happening on my Tab 2 - 7´´ with the Lineage and the AOSP ROM too (with Slimkat all goes well with offline charge, for example).

So, does anybody know how can I turn off (or change) the script that does the offline charge on this ROM?

Thank you in advance!

I'm a novice at this rom upgrade stuff.

I have 2 P5110 tablets and firstly tried upgrading the stock roms to CM13 & gapps-600-base-20151114-1-signed but both units keep crashing and rebooting. I didn't want to completely wipe the old roms and loose data & apps so just overwrote existing roms.

Having failed with CM13 I saw this thread and have flashed 1 unit with Lineage 14.1 & open_gapps-arm-7.1-micro but on rebooting it seems stuck in a boot loop with the blue arc and circle moving right to left (doing this hours before turning off). I flashed using twrp-2.8.5.0-p5110 as the newer unified version wouldn't run and I couldn't find the .tar version only a .tar.md5 which I wasn't sure would flash with odin so I flashed the zip version using the older twrp. Perhaps this is the problem?

Perhaps you've already addressed this issue in a previous reply but I haven't had time to read every posting.

All suggestions eagerly awaited.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] john99ap:
First of all, you should always do a clean flash when switching roms.

Second, Odin can flash .tar.md5 files.

Best you can do is install the latest unified twrp, then wipe system/data/cache/dalvik cache and install whatever rom you want.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] rebgershon:
Many thanks for your speedy reply.

I did try to flash the md5 file but there was no boot into recovery. When you say do a clean flash I presume you mean losing everything installed already?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] MetalIris:
Clean flash: wipe system, cache, data, dalvik cache. If you're trying to do TWRP via odin you need the .tar one.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Taranis:
I use this tablet and some older version (4-8 months old; EDIT: probably 6.0) of this ROM and I'm getting a lot of slowdowns, especially when multitasking. Same slowness was on older builds too, I haven't tried the latest one (I have to modify a boot.img before installing).

I use it in my car, 1-4 times a week. I use 1 app in background (uses GPS to show nearby police) and Google Maps, sometimes music in the background (that are just 3 apps, but freezing as hell). And Google Maps are killing my tablet on this ROM. I have to wait like 20-30 seconds (staring at logo), then wait another 15 seconds to load a map. I know that this tablet is not new, but I wonder if I should switch to KitKat. Priority in my case is multitasking speed and performance. Actually the Google Maps are the worst. Like it was handled by CPU only. Sluggish and like 100% of CPU is used in the background.

What would you recommend me?

Going back to KitKat or update to newer build (staying on Marshmallow)? Not sure if KitKat still works with Google Maps, but a long time ago I remember it was a bit faster, but that might be due to older APKs...

Buying another tablet would be big issue, because I have it installed permanently.

PS: I don't have many apps, I reboot it regularly. I have 3G version.

My point is just to say that's is a pity to let this device without any LineageOS rom update as it is known an old but good device, quite largely spread (and hence many users), the TWRP image is also available. I mean, there is everything we need, many prerequisite to make support of Galaxy Tab 2 not so hard. That's why I was looking for co-maintainers so that we can together still support this device.

---------- Post added at 11:35 AM ---------- Previous post was at 11:06 AM ----------

I'd like to sum up what is the situation of the Galaxy Tab 2 (7" and 10").

TWRP for p5110 (Galaxy Tab 2 10" Wifi) is discontinued but it has been continued as unified TWRP espressowifi. This espressowifi version of TWRP works on: p3110, p3113, p5110 and p5113.

LineageOS is no more available as an official build for Galaxy Tab 2, but there is some builds that has been made, up to recently, by [MENTION=5153662]Android-Andi[/MENTION]

this page from Android-Andi is proposing LineageOS 11, 13 and 14.1

[MENTION=4122877]curiousrom[/MENTION] preferred to stick to LineageOS 13 as he found LineageOS 14.1 too laggy

I personaly be willing to continue support LineageOS for Galaxy Tab. Eventually officially if possible. If anyone volunteer to join me in this task, please tell me!

If you like to continue official you'll have a lot of fun:

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] gratindauphinois:

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Android-Andi:
Feel free, source is open. On Oreo a lot changed which doesn't make it easy to get it booting and in a working state. You can't get JellyBean driver and blobs to work forever. Old DDK. Kernel side there's a bunch of backports needed. And so on.

Nougat doesn't even work as it should (lot of lag, RIL needs a workaround because it's not properly fixed) I am not sure if it's the right way to jump on a more complicated base yet. But feel free.

To keep this thread for what it was made for: development related questions, answers and news for LineageOS14.1,

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] hollandais:
Some of us already tried an os15 rom. OK, it works, but that's the only thing I can say. The tab became very, very laggy, unexpected reboots an not enough memory. So if the only thing you want is telling your friends that your old tab is charged with OS15, OK. But if you want to use also your tab as a daily tab, try another ROM. My experience, and I have some, is that the best ROM for our device is an Android 6. And I prefer RR 6.x.....
