That's pointless, then you can ditch the whole tablet because EVERYTHING is obsolete by todays standards. The screen is low resolution, battery is awfully slow to charge, headphone DAC is full of noise, processor is ancient and makes everything slow, etc etc. To ditch features is not the point of this community, it is to make new software adapt to the old hardware so we can use it again.

I used the front camera a lot last year and this one taking college classes via Zoom. It's the only tablet I have, don't want to buy another one and make electronic waste when I know it's perfectly capable of doing things like Zoom, even if the other people can't see the details of my ugly face.


Ps: I say all of this to try boost morale, with total respect for the devs. I wish I can help more but I'm a noob, I do what I can but bug hunting takes me weeks, even for something simple like the bt bug I worked on. I will be helping with what I can but please, don't make this another "just web browsing" kind of release...
I can understand you. My situation was same last year but not so bad. Good thing my parents bought me a laptop this year for my school's, tuitions

And yes, we would be working on the stability issues and camera by using the 3.0.101 kernel on the Tab 2 with oreo. The only issue is that @Mighty have a weak laptop that almost cannot build roms. We have to ask for help from developers like @html6405, which as they have a lot of devices to maintain, won't be the fastest update speed.
Cameras are very unlikely, if @html6405 manages to get 3.0 kernel working with oreo there is some chance, but with 3.4 kernel its a no.
BTW, I'm already having a booting 3.0.101 Kernel with working OTG, dock keyboard and many more functions.
It's still unstable, because there are many other commits and backports to do.

I've fixed the camera hal partly, so that it's buildable, but the camera doesn't work so far (I think it's a hal problem),
also, I've found a partly RIL fix, but at the moment only the BASEBAND is known.

Because of other ROM updates, I think will proceed in november with this...

I'm using slim7. Never tired RR rom. Is it better than slim7 in overall performance?
Should I downgrade?

@Mighty is having problems with building the rom due to a weak laptop
If they are interested, they can use my computer to build roms.

Send me a DM or something so we can get going. I have no experience building android roms, but I have enough experience building web apps to automate it, with your help, so you can just upload the sources and get a build done by my hardware. Hopefully the delay of uploading the entire source code and downloading the artifacts is less than the time you save.

New Update for espresso3g!
Updated lowmemorykiller
We are using 64 bit binder, instead of 32 bit binder (which was for android 4.4)
Fixed wifi, no more patches needed!
Removed zram as it was causing freezes
You can install apks more than 100mb now
The build is ported to espressowifi. Post #175 is updated.
Thank you @Mighty for the stability fix. It is not until now for the tablet can be meant to be used as a daily driver.

As one may argue, in fact yes you can use zoom, but you have to say that your webcam is broken to your teacher or manager, with a stable OS that zoom (100MB+) can run on.

I mean, only few teachers insist one to show their face in zoom lessons, does they?

I know that many people need cameras but it's something I cannot fix, cameras are handled by the 2x Cortex M3 cores which are handled by a proprietary blob given by TI. The original was for 3.0 kernel which had camera support but the one for 3.4 kernel doesn't, ig we can ask TI for some solution but idk

    Hello,

    i've seen this thread some days ago, and did try it on my GT-P3110. Great work, some things what i found which could be checked from other users, if they occur there, too.

    - after using it for some hours with testing and installing/deinstalling apps the cpu keeps at 100 %
    - a tool shows that both cores are all time exact the same - does maybe only one core run, and is shown twice?
    - Edge browser or Chrome works. Whern trying to play videos, there is no sound, and acceleration seems to miss (?)
    - trying to use two apps from foreign tv, i got errors that streams could not start.

    In spite of Omni/LOS/RR 7.1 it seems not to freeze one core by rebooting the device. What could be done for checking the difference what has changed to get rid of the problem in the older builds?

    I wish i could be more helpfull, but i'm only an advanced user by now.

    For that error 7 problem while flashing, i've read somewhere in another thread to try this:

    In TWRP, open terminal. Write there:
    mkdir /cache/recovery

    After Enter the next try to flash ended fine, i'm writing with my tab 2 now.

    Regards
    The ROM is espresso3g the GT-P3110 one is espressowifi version

    EDIT: Try Restarting to the Recovery again (error 7)

    Somehow nothing was flashing properly on that even after rebooting recovery. It flashed properly after flashing the TWRP 3.3.0-2. Ill check again with the 3.4.0-0 maybe.
    Use the common twrp by Andi, http://andi34.github.io/recoveries_tab2.html

    @Mighty is correct. This option is not available in any aosp roms (at least for tab 2) I notced that earlier. In Lineage OS or Resurrection Remix, it is available.
    not only for tab2, it should be for no devices with aosp roms

    I don't see the option to enable "advanced restart" in the "developer options" .....
    Correct me if I'm wrong but dont think that's available in aosp roms, maybe in LineageOS it is

    Great to see that development continues!
    Thanks a lot @Mighty and @html6405 !

    From time to time I am reading on XDA or taking a look at our dev chat Channels, even if I am not a big help anymore.

    I am spending my rare spare time working on a OpenSource Photobooth project, mainly to run on a raspberry pi.

    My daughter was born end of August and now new, different challenges are waiting for me!

    Best regards

    Yeah, I agree with you. @Mighty, you better change your name to Almighty because many devs tried to build this rom but failed. Only you were successful to get the rom even booting in tab 2. That's really a big step forward.💯🏆⚡🎉🎆
    Haha, thanks a lot! It's my pleasure to work on tab 2, and many thanks to Ziyan, Andi, html6405 for helping me out!
