[SOLVED] Need help to build an unofficial nougat /e/ROM for the Samsung Galaxy Tab 2, espresso3g GT-P3100, GT-P5100, espressowifi GT-P3110, GT-P5110, GT-P3113, GT-P5113

/e/OS Devices UnOfficial Builds

Hello,
I do not have material resources (and not yet experience) to build an /e/OS image for the ROM of a Samsung Galaxy Tab 2 7" WiFi GT-P3110 espressowifi
I have installed the official Replicant 6.0
(works slowly and without wifi and camera)
and the Android-Andi’s UNOFFICIAL LineageOS 14.1
(works very well after some reboot, but with the Lineage’s gogol leakage)

I really like /e/ and I should be happy to run it on my child’s tablet

we have a wiki for building lineageOS for this device
https://wiki.lineageos.org/devices/espressowifi/build

we have a technical description for this device

https://github.com/LineageOS/lineage_wiki/blob/master/_data/devices/espressowifi.yml

GitHub - LineageOS/android_device_samsung_espressowifi

on XDA, there are this Tab 2 general forum, this entry-point forum, and this working ROM forum

some recent well working versions are already aviable for this device
unofficial LineageOS 14.1 espressowifi
unofficial LineageOS 14.1 espresso3g
built by a german guy Xda-profile / Github-profile
And also exist an overclocking kernel

I don’t have the good computer, so I need some help
@builders thank you by advance for your help

Well, I’ve updated all my local sources and compiled a fresh build of LineageOS 14.1 - is it really worth?
Android 7 never had a good performance on our old loved device.

It was abandoned on Android 4.1.2 by Samsung in most regions, only a small amount of user got official 4.2 builds.

We’ve brought Android 4.2, 4.3, 4.4, 5.0, 5.1,6.0 (including all subversions) to it.

Isn’t it time to say R.I.P. Tab 2?

I’ve made 2 adjustments and the build is again compiling. I’ll upload it to my androidfilehost account once it’s ready - but don’t be sad if it’s a slow thing in the end…

I’ve also patched my 4.4.4 ROMs a little bit, going to recompile them too. Maybe you better stick to an 4.4.4 or 6.0.1 Rom as the performance is a lot better on those.

Just my 2 cents.

I suspect that the performances will not allow for complicated games, that’s not my intention.

Your version of LineageOS 14.1 is fully functional for basic functions (if you are indulgent with the machine).

As I said, I’d like a port of /e/ on this device to simply enjoy the advances in privacy

My 2$ ( inflation)
I purchased a new tab for work. 8 am I punched in, scanned docs on a new car. 8:45 tab hit the floor. Thank God I have insurance. That tab stays home with mama.
My 5113 survived this long. Grandkids used for hockey ( practically). @Android-Andi your 6 builds are pretty good. Seems the guys at ua updated things in December. Everything is good.
Thanks for the build.

I am one of those who “work” at UA (unpaid) :wink: for all of us private life changed and development isn’t active as it was in the past.

Yesterday i took the whole day to update my local sources again and Update 7.1 (April 2020 ASB) and 4.4 ROMs with some security updates. Only on UA Jenkins is currently not working.

Btw. For Nougat builds on Ubuntu 18 people might run into an compilation error depending on flex which can be solved by Cherry-Picking https://review.lineageos.org/c/LineageOS/android_prebuilts_misc/+/229452
else you need to run export LC_ALL=C

thanks for sharing infos,

lineage-16-0-20240709-unofficial-espresso3g-zip

Working:
-Charger when tablet is powered off
-Sensors
-Audio
-Vibration

Not working/Known problems:
-WiFi
-Tablet can’t wake up, it needed to be force rebooted to work again (it’s earlysuspend fault)
-Sometimes crashes occurs (and displays colorful tv noise)
-Files app is crashing (android can’t mount /sdcard)
-Can’t do screenshot

Won’t fix:
-Camera (because I already tried to use 3.0 kernel but it doesn’t boot and in 3.4 the kernel, camera does not work)

If I missed smth, tell me + provide logcat Grinning face :grinning:

from the same period
we already have :

[CUSTOM BUILD] Samsung Galaxy Tab 2 (espressowifi / espresso3g) for /e/OS-Oreo and Pie

Problems:
Many things WILL BE BROKEN considering this is an early build. Please report the issues so we can fix them.
Cameras will NOT work, as we are using a newer 3.4 kernel for Pie!
GPS
The tablet does not charge from 0% according to some users (https://xdaforums.com/t/rom-aosp-8-1-oreo-unlegacy-android-unofficial.4323203/post-87301845). PLEASE DO NOT DRAIN IT COMPLETELY until a fix is found
First boot will take some time, have patience.

  • the tablet doesn’t wake up from sleep, it needs to be force rebooted to work again
  • wifi is broken, impossible to activate
  • the interface sometimes crashes, changing the theme also triggers the crash (and displays a beutifull colorfull tv noise [image] )
  • auto brighness don’t seems to work
  • the nav bar icons are glitchy
    THIS IS NOT A DAILY DRIVEABLE BUILD
    You tell [image]

For best experience on this device, android 6 based builds are recommended but it is not possible with /e/ sources that start with android 7.
