The download servers and build servers will be undergoing maintainence over the coming few days.

That means that downloads for espressowifi and espresso3g builds may not be available through the pavela.net domain. Once the maintainance is done, it should allow the build server to be up more reliably.

More information about server status is available here: https://status.pavela.net/

And the Jenkins build server with espressowifi and espresso3g builds and their logs can be viewed here: https://jenkins.pavela.net/

I've uploaded the latest builds to a mirror. Use these links if the pavela.net domain is down. These builds are the same as the ones uploaded earlier, just in a mirror while the download server will be going through maintainance.

DOWNLOADS:

espressowifi

espresso3g

Once maintainance is done, automated builds for espresso and espresso3g and access to more builds for more devices should be available soon™

Hi everybody!

I'm sorry for any misunderstanding. I don't speak English very well, so my translation can be strange.

First: I wanna thank you for the developers. You have ressurrected a great Samsung Tablet. This 8.1 version is so good!

I came here because I wanna ask one thing: There is some way for use a custom kernel in this tablet? This version is running unbelievably for the hardware in it. But a "upgrade" would help a lot in games.

I saw in the "Kernel toolkit" that the processor is running at the frequencies; 300, 600, 800 and 1008 MHz. Would have able to increase them? If so, thank you. If not, thank you too, because this version is great! Thank you for all the effort and dedication.

Anyway: I'm sorry for my bad English.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
theres likely a way to compile the kernel from source with an overclock, but i dont know how, although some searching for ti omap custom kernels should help.

i wouldnt recommend it tho, because this tablet lacks a temperature sensor, so it'd easily overheat and die.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Star_and_Moon:
Thanks for the reply!

Oh, I see. Do you know some compilation here, in XDA?

I hope that in the future there will be a custom kernel for it. But for now, this rom is already impressing me a lot for its speed.

Hello, thanks for all the work on this ancient tablet!

There seems to be quite the jelly scrolling effect going on in System Settings. I have yet to install gapps, so I haven't checked to see if it happens anywhere else. Is this a known issue?

Hello everyone. I'm having trouble with my P3113 where after flashing the Feb 2022 build of the 8.1 rom (with TWRP 3.3.0.2 i believe) It worked but the battery was showing 0% so i naively powered off the tablet and it's not powering on back. When the tablet attempts to do offline charging, it just shows a black screen which is using the battery as it tries to charge. I tried leaving it on the charger to see if it could get some charge but the results were a very hot tablet and no charge. It can't even boot into TWRP anymore. I was reading where someone mentioned that TWRP 3.4 was the recommended TWRP needed to do this. I failed in that aspect. Have i just bricked it?

PS: something similar like this happened when i was attempting to flash unlegacy 6.0 that did not have offline charging screen but that did not require newer twrp.

Or basically you just need to charge your tablet for hours (11+ hrs for me) then you can turn it on
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Alotheone:
Could this still work with a non-genuine cable?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Yxles:
Yes it should, just left it to charge for hours. It's fine when the screen stays on black screen just left it there
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Weird issue about not being able to charge from 0% sorry for the problem, i'll look into it later, for now i'll put a warning

And as your tablet gets very hot, some cooling solutions like a stand + fan may be useful to prevent permanent hardware damage
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
especially to the battery! you do not want it to expand (screen can pop out or worse, note 7).
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Alotheone:
I'm back after 3 days and i have some things to share.

I tried the 11+ hours of charging starting last Friday and ended last Saturday: It did not work. I wanted to try it again but i had somewhere to be at the time so i left the tablet off the charger and went my merry way. Monday evening when i came back i tried charging it and it showed the battery charging icon and then just shut off, which was a good thing (from my experience installing UA 6.0.1). After allowing it to charge for 20 minutes, it finally turned on. I learnt that i must never allow the tablet to reach 0% whilst on this 8.1 rom and never try to charge it when powered off.

I'm honestly impressed at the performance of the rom with gapps (pico). Battery life is also amazing for a decade old tablet on this 8.1 rom. There are some things i noticed so far:

1. I realized that the tablet was killing the apps upon leaving them, turns out that hardware acceleration in developer setting is turned on by default. Turn it off and you'll see apps stay in the recents app menu.

2. When going on a app and leaving it, in the recent apps menu the app preview is very distorted.

3: When using the clock app in the form of stopwatch or timer, the notification will not show and a pop up notification about "developer warning" will show.

Those are my experience with the tablet (P3113) so far with the February build of the 8.1 rom.

For any future builds please add offline charging screen if possible.

PS: i also noticed that my battery drains by 2% mostly instead of the usual 1%. IE: From 77%-76%-74%-72%.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
The charging issue was also on UA 6.0.1?

1. "hardware acceleration in developer setting is turned on by default" that wont affect killing apps right? It most likely is due to Oreo Go configs that we use.

2. Known issue, I havent found a fix yet.

3. Could you explain a bit more?

https://github.com/Unlegacy-Android...s/base/core/res/res/xml/power_profile.xml#L61 tells android that betters is 6860mAH which might be the cause.

Thanks for the review!
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Alotheone:
Your welcome for the review. To further explain:

1. The whole killing apps thing was happening for me before i activated developer settings. I really wanted to stop it from happening so i searched the whole settings for a fix which lead me to developer options. After activating developer options and looking through it, i noticed that hardware acceleration was turned on by default, so i turned it off and the killing apps problem was rectified.

3. I noticed that usually when using stopwatch or timer, a notification would always show up in the status bar. When trying to set a timer or start stopwatch and exiting the app on the tablet, the notification would not show and the pop up message would say something about developer warning as shown in one of the screenshots from my previous post. Again, i must say this rom is amazing. Its faster than most of the 6.0.1 roms i've used in the past.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
@Mighty wheres the latest build for this tablet? (espressowifi's latest build is febuary 13, which is before the SELinux patches)

i could build them myself, but are the instructions identical to those for unlegacy android? (just syncing your repos instead)

also, couldnt we try overclocking this tablet? i know it doesnt have a temperature sensor so its a little dangerous, but a slight overclock could help alot. id like to overclock that miserable gpu but i dont know where to start with powervr overclocking (ive built overclocked kernels only for mali g31/cortex a53 s905y2, which isnt a very hard chip to develop for)

EDIT: i found the opp table for the omap4 (found it by looking at overclocked gpu kernels for other omap4 devices), so overclocking this tablet shouldnt be very hard at all, however its quite dangerous as it lacks a temperature sensor.

still, i might do it at some point since i think it would be kinda funny.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Daniel071:
Yes, my build is outdated and I will work on building updated versions with the latest patches when I have to time to do so.

Have a look at my post here:

https://xdaforums.com/t/rom-aosp-8-1-oreo-unlegacy-android-unofficial.4323203/page-15#post-86354459

And look at the build guide section, where I put instructions and guides on how I built for espressowifi.

Here are the build scripts I use for espressowifi and espresso3g. android-build-scripts (Github)

And yes, you can make the change in the opp table for overclocking and build it if I remember correctly, but not recommended.

I'll post it here as well.

Spoiler content hidden.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
There was an overclocked kernel at one point, somewhere in xda is the thread and its sources, about overclocking the gpu, https://github.com/andi34/android_omap4_pvr-source/commit/918432a71ddb2428ea87caf70f23ca70c2daaea2
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
the local manifests would throw an error (fatal: duplicate path device/samsung/espresso in /home/xx/android/lineage/.repo/manifest.xml) as the manifest.xml was including some other manifests that pointed to /device/samsung/espresso, so i had to remove those lines too

EDIT: my build computer is running linux mint 21 (which is ubuntu 22.04) and that seems to be a bit of an issue compiling older android as it seems to still use some python2 code. (probably also old code for other stuff that might not play nicely with newer compilers/interpreters)

i downgraded to python2 and i hope thats the only error i get, as im quite tired from the new years. its 3am and id really like to sleep..

also ill try to compile for both wifi and 3g variants, however i can only test on the wifi variant (dont own a 3g)

oh and yea, happy new years everyone!
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Catfish78:
After a while, i've retried the build on my tab 2 wifi. By now, it's running not that bad for a now ten years old tablet. Funny for me is, that some apps (i've flashed gapps, too) won't work first, but do work fine after an first update by the play store.

One thing i do not unterstand is, that my Browser downloads something and saves it, but if i try to localise it, it's not there. Hitting the "download ready" message opens it anyway, and i can save it somewhere.

Until now, this Android was working fully stable.

Helping to get another working version with last updates: until now, i am too stupid to get that procedure done.. I've failed a year ago with it.

Just as an idea: i've charged it in twrp for testing purpose, but not under 15 %. Maybe someone likes to try that, if in trouble?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
im using brave browser (chromium based) and it works fine, what browser are you using?

its not so hard, its mostly just the fact that 8.1.0 is outdated build wise (still uses jack to build) so it doesnt work properly under modern linux distros.

i had to spin up an ubuntu 18.04 vm just to get it to build successfully, and the build doesnt even boot anyways.

@Mighty did you ever test the patches you added for SELinux? because my tablet wont boot with the build i just compiled, and im wondering if ive done something wrong.

i have built android multiple times in the past so i sorta half know what im doing, but in this case i honestly dont know if i did something wrong or if there's something with your code
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Yes I did test SELinux and it worked fine for me, I might have the build somewhere xD

Wdym it doesnt boot? Goes back to twrp? Bootloops?

Anyways once 8.1 has bugs squashed, which I have no idea how (power saver, cold booting etc) we could easily go to 9.0
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
it shows the galaxy tab 2 screen, flashes and then shows black

i had this happen previously when i flashed the wrong kernel, so theres something probably wrong with the kernel, and i thought it was SELinux.

i guess not, seems like ive done something wrong.

wait, whats wrong with power saver?

also, we should probably work on moving to lineageos sources, since they're quite a bit easier to work with than UA/AOSP (UA is abandoned too)

EDIT: im going to try using 16.04 (the version UA used to build) as i know that sometimes newer compilers can cause issues with source code, although i feel thats unlikely if you got it to compile too.

what are you using to compile this? im honestly really stuck here as to why my build wont work but yours will, since we're working off the same code..
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Catfish78:
Don't hit me, i'm using Edge. The alternative, Firefox, which is on my main phone, is not working here until now. Edge works fine, only that download issue is a problem in my case . There are some graphic errors by showing empty tab bars, but that's ok.

Maybe i'll give it a try again, if i find the time. I don't own fast PCs, but i think it will be fast enough for it, with some extra time.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
may i ask why you are using edge? 😅

also, if i remember correctly, firefox did work (slowly) on 6.0.1

anyways, edge is chromium based so i dont get why it doesnt work while all other chromium browsers work, so its probably an edge issue and not a problem chromium and this rom. (ive used brave to download games and stuff and it works perfectly fine, even with big files ~700mb)

maybe when you want to download something you may want to switch to a different browser, or just use a different browser entirely.

this bug does sound like a microsoft bug tho, so its not really got to do with this rom specifically.

also, those graphical issues with the tabs is something to do with this tablet's gpu/gpu driver, the SGX540 behaves strangely in lollipop+ for whatever reason, its not slow or anything but just buggy and bizarre, so this stuff is to be expected and nothing really scary.

aight, if i manage to succeed id be glad to help.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Yup gonna move to Lineage (sources are on my git :P), will just build on my laptop now ssince im pretty bored :D

So if its showing a black screen, can you connect usb and does it get detected, also can you hear any audio? Maybe the display is being blocked by SELinux (its very irritating)

Regarding power saver, i dont remember the exact issue, but it just fails to turn on
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
i noticed those, what's their current status? i kinda wanna try those too..

i thought that too, but the backlight was on and i expected it to dim, but it didnt. also i somehow lost the usb cable for this tablet, and im now only able to charge it (i charge it with an iphone 30-pin connector)

oh, last time i tried it i think it worked but i dont quite remember..

ill try that out.

EDIT: once again it doesnt boot even building with 16.04, which device did you test your SELinux build on @Mighty? mine's p5113 (espressowifi)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Gimme some time to build it then, currently i took up halium xD

Cant do both at the same time
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
building lineageos or UA with SELinux?

i might try to build lineageos, since ive got spare computers i can run the build process on. (although ive been busy with some other things)

also, i noticed you were working on postmarketos for this tablet, how's that going? does it have gpu support yet? (obviously with the proprietary gpu drivers)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Catfish78:
I'm using Edge because i have my reason , and, as told, i use other browsers, too. :-) .

Edge works on the Tab 2 stable, only this "my download is not in the download folder (or anywhere else)" makes me unhappy. On other reflashed, old tablets/phones Edge do work without issues. I do not really need the Tab 2 as a daily driver, just thought about silent users which tries this build.

If i would get enough time, i would like to learn how to build those aosp/lineageos or else OS alternatives by myself. But i'm more of an physical worker than working at software. I'm barely just too old i think.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Nah, Halium/Ubuntu Touch and LineageOS, anyways I'll work on Lineage today hopefully

Yeah postmarketOS is going great we got a community release and support for all Tab 2 (P3xxx and P5xxx)

GPU support is here - https://gitlab.com/pvrports/pvrports/-/tree/v22.12
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
aight, tell me how it works out

ill most likely try to compile it too

oh, ill probably install it once i find my usb cable.

this tablet has mainline too?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Catfish78:

Hi everyone.

I tried to install gapps arm 8.1 stock but tablet havn't enough system space but i have 12 gb free space

What can i do ?

thanks
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
its referring to not enough free space on the /system partition

install a smaller gapps package, or dont use gapps at all (i dont and it still works fine).

if you use a big gapps package and it was able to install onto the system partition (eg. by resizing the size of the system partition in the pit file) it would likely crash anyways, so you'll need as lightweight as you can get.

With pico It work but it's too slow

Which roms Is faster ?

Maybe with Android 6 marshmallow?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] luchettodj94:
The dhollmen rom based on marshmallow is the more stable, is also pretty fast (there was couple rom that were faster than this but in long term they were not that good, speacially in heat and battery) and it have an amazing battery span, there is also a custom kernel but i didn't tried it yet.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
be careful messing about with the cpu

for whatever reason (probably to cheap out) there is absolutely no thermal monitoring on the omap4430 therefore it can literally cook itself, so be careful..

yeah, the old lineage 14.1 i used has some sort of problem and never fully shuts down, if I press power off there is a certain chance of it heating up out of nowhere and almost burned my house down, if it have some thermal solution it won’t be so apparent.

no unfortuneatly thats the build i was using, but i hadnt applied mighty's changes properly and it doesnt seem to have worked.

or maybe it has, but my charger is unable to provide enough amperage

most likely if you have a 1A charger, you should be able to charge from 0%

but just play it safe and dont discharge to 0% on espressowifi until a tested build is released with these changes
