Oh wait, I'm sorry I get it now. I don't have an original adapter, but it's good as long as it has enough power right?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Correct as long as it gives enough power it should be fine since charging from 0% is handled by the bootloader which we do not change anyways!

But better safe than sorry just don't let it go to 0%

Can you also recommend something similar to ResurrectionRemix, but this time for Galaxy Note 10.1 (GT-N8010) ? I don't search for the latest, but for the lightest and fastest suitable solution for such old tablet. Thank you in advance!
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] An2rejKK:
Thanks for this rom, can i use it and add some by me Samsung ported apps, and do some litle tweaks and kernel changes? I would give you credits.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] codingPotato:
Hello codingPotato here,

Thank you for the great efforts put into making this rom. I just got my hands on one of these little old tablet and as a developer I want to tinker with it of course. The tablet is very slow and hard to work with given its specifications and old hardware. However, I think it may be possible to get decent performance out of it to a point where it is useable. At this point this rom barely works and it's not good for anything other than flexing that you have android 8.1 on such an old device. I hope that I will be able to collaborate with you to achieve my goal of making it useable.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Yeah feel free to!
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Would love to achieve that goal myself! 8.1 is much smoother than 7.1 plus we're using Android Go configs (specifically made for weaker devices with <1GB RAM). The sources are public and open and I'd love some contributions to make the device better! <3
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] An2rejKK:

Hi everyone,

Thanks for the rom, I’ve installed it and it works pretty well, needed android 8 or higher.

One issue.

When the baterry is fully charged and tablet is connected the screen turns on and it does it on and on. Can this be turned off. I tried to find the setting ‚Turn on screen when fully charged’ to toggle it off but it’s not there.

Any tips?

Thanks

hey everyone

just want to ask, how do i enter download mode?

i already tried volume up and power button, nothing

volume down and power button, also nothing

my power button is a bit scuffed up (i had to use a screwdriver to turn it on), is there any way i could boot into download mode by force so i can install twrp?

edit: found out that my other volume button is dying, i'll try to do it with multiple screwdrivers

edit 2: it finally worked, even though no one replied!

Hi guys, new to this forum, and very much needing your help!

i have a P5100, and I am trying to upgrade it as per the instructions in the very first post.

I installed TWRP 3.4.0.0, tried flashing espresso3g, no luck : Zip file is corrupt!

Tried downgrading TWRP to 3.3.0-2 : same result.

What could have gone wrong?

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] RDS5:
it would be useless anyways, most treble roms are moving to arm64.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] LR7875:
not mentioning the best we can do to get it to work on treble probably only be A-only, which is dead since A12. what we actually have a meaning to do now is to compile an android 9-13 rom for it and maybe blind build it for other ti omap devices probably idk if that would be a good idea.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] maxime49:
Hi guys, I'm encountering a semi-brick issue with my Samsung Galaxy Tab 2 GT-P5110 wifi which I left at 0% battery and I've tried the procedure you mentioned without success.

My Samsung GT-P5110 wifi is running a custom ROM Lineage 8.1 (ua_espresso-8.1.0-20220213).

Despite leaving it connected to the official charger for over 11+ hours, the screen remains black, with only the backlight functioning. It is impossible to access to download or recovery mode,

Additionally, I've attempted leaving it disconnected for over 11+ hours before attempting to start it up, but there's been no change.

I've tried the technique of letting the device decharge and trying again and it doesn't work.

The only sign of life (except backlight functioning) occurs when I follow this step :

First check your wall outlet, charger, cable are working or not.​

If yes, Then plug the cable to ur tab and pc​

then press power button for at least 10 seconds,​

then while holding power button press volume down button for another 10 seconds​

then release the volume button while still holding the power button for more then 10 seconds.

the battery icon will appear.wait for some time b4 releasing the power button.

This turns the battery and loading logo on and off in a loop.

Any further suggestions or insights would be greatly appreciated. Thank you for your assistance.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Lenilam:
Hello everyone.

As I am French, I apologize for the translation, which was done with an automatic translator.

I hope that someone will be able to inform me about my problem, knowing that this tablet is obsolete, and that this discussion thread is dated.

for information:

I installed the Rom on my Samsung Galaxy Tab 2 10.1 GT-P5110 wifi.

TWRP is installed, and the tablet is rooted.

it works, but the playback of movie videos whether local or YouTube are really jerky, as if there was no GPU hardware acceleration, or that the GPU was not used, moreover the processor is 100% when playing.

I tried VLC unable to play correctly.

I tried MX player, no better, normal because only the SW decoder is selected which is a software decoder from what I read so it is the processor that works and not the GPU, I wanted to activate the decoder HW (which uses hardware or HW+, but it tells me that they are not supported, for information the codec used by MX player are ARMV7 Neon, the default codec.

I don't understand, yet this ROM has integrated GPU acceleration.

I haven't seen anyone mention video playback issues in this thread.

There you go, thank you in advance if you take the time to respond, especially since for the moment this is the only ROM with Android 8.1 that I have found to run my banking application on this tablet.

a second problem, which is a bit problematic, is that the tablet does not charge when the tablet is turned off, and I plug in the cable, the logo is displayed once without showing any animation and loading, and disappears and then the screen stays slightly on, and does not turn off.

The only way to recharge it is to charge it when the system is started.

ah yes, I forgot, if you know of a different custom ROM with Android 8.0 minimum, which works well, I'm interested, thank you ;
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
This is the only 8.0+ rom that i know of, and i dont know of any other developers still making roms on this device. I'll be soon getting back on Lineage 16 and more once i get spare time :D

About the video acceleration, I did add few patches https://github.com/MightyM17/android_frameworks_av/commit/2df86cce763e0e5135fcdef3ed34fcf5f4c3efa8 which should have gotten video working (it worked for me during testing) so not really sure whats going wrong there, will test it again.

The charging is a known issue, try not to get the tab to 0% (charge it beforehand) the bootloader should set the flags for charging and it should work but seems like android isnt initialising the display https://github.com/MightyM17/androi...mmit/006c87bf8a4fc1a38816b239a0e951c828963b28 lets see if this works

OP simply means the person who owns the thread/started the thread, meaning Mighty is the OP here ( OP stands for original poster) and hes telling you to read post #1 in this thread to know what are the known issues, as OP stated clearly that camera will never work as these old camera drivers are incompatible with a 3.4 kernel that this kernel uses and requires probably due to some broken functionality with older kernel, and also that theres an issue with the tablet abt the tablet not charging when powered off, and for that fix seems to be known

I had tried

LineageOS 11-espressowifi

the camera is working(no film), no sound, can charge.

camera is not working, no sound, cannot charge.

ua_espresso-8.1.0-20211021

camera is not working, got sound, cannot charge.

The charging means when the power off.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] LR7875:
Nookhd is omap 4470 according to Wikipedia.

Devices with the same SOC should be Galaxy S2 I9100G (Notice the 'G'), motorola droid 3/Bionic/ RAZR and kindle fire.

All of these are running on android 6 or 7.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Yeah I know but nookhd is the only omap4 device running Oreo so I didn't have an option there (no omap4430 device runs oreo)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] LR7875:
Well even nookhd oreo build did not get the wifi working.

The 'fixed' is for fixing bootloop, not wifi.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Oh right, i thought nookhd had wifi my apologies
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] LR7875:
Well is it a coincidence or not................................?

Does the nookhd build use the same 3.4.0 kernel?

If that is a case, upgrading to a even newer kernel like the P75xx tab 1 10.1 does, or hacking and use the original 3.0.101 kernel that the galaxy s2 i9100 exynos does, might be the only useful lead thouh that is truly a daunting task.

Also did the sailfish os kernel 3.4 work WiFi? If that has WiFi we might have the last hope of getting kernel 3.4 working.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Sailfish with 3.4 kernel is well another task, check the sailfishos-porters, I cannot ssh nor telnet there now.

For the other option of using 3.0 kernel, I dont really know if that will work :(
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] html6405:
Sure, this also should work, my exynos4 devices are all running with 3.0.101 Kernel and this perfect with android 9 and also very good with android 11.

But there's much work to make it compatible.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] html6405:
When I started with oreo, there were many problems so that I decided to not publish it and moved directly to android 9. (There was a local build, only for me)

All the new changes which came with oreo were improved in Android 9, so it was easy to overtake the work nearly direclty to pie and proceed there.

It maybe was more an OS like Windows Vista 😂.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] LR7875:
Yes agreed.

More like an windows 8 ( version number matches)

@Mighty

Well in my opinion the next to try compiling Android 9.0 or newer with kernel 3.0.101 and see if it works. I know nothing about the problems and work needed so, forgive me as I am a noob if I requested too much.

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

Congrats on getting a successful build of android 8.1!

I have already flashed the ROM and I did some tests. Internet is not working but this is known however Bluetooth internet also isn't working but yet I was able to pair my Bluetooth headphones and they worked so Bluetooth could be half broken?

System sounds are not heard through the built in speakers but when I tried running a simple app like angry birds it ran and worked fine, there was audio through the built in speakers. So far it seems like this is going to be a great ROM once wifi will function! :)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Mighty:
Yeah, internet itself seems broken and its most likely a kernel issue, we are missing some stuff for oreo (which we dont know what :()

Hey Mighty and all people that are helping him getting things to work:

Thank you very much!! That is very cool getting Oreo to work on our Galaxy Tab 2.

Updating the software of some old hardware that still works perfectly rather than trashing it, is the spirit.

Just for the record:

I did install your ROM and so far it works fine, except the stuff that is missing.

I tried if internet works with an USB network device, as some older ROM from Andy do work with it, but it turned out that it was not working either.

Keep up the good work. I'm keeping fingers crossed that you iron out the open bugs.
