It seems like on certain pure AOSP builds, you need to swipe from bottom all the way up to top of screen to unlock.

i only follow tutorial on andi only

Update:
If you want to fix your tab at your own risk, try this:
1. Download both espressowifi and espresso3g zip
2. Extract both
3. Put the META-INF folder from espressowifi zip, and all other files from espresso3g zip, into a single folder (The other files are not placed into the META-INF folder, but alongside one another in the folder).
4. Go into the folder (which should contain META-INF, system.img, and boot.img, maybe more), select all files, right click, then click compress into zip file. Then flash that zip.
5. Happy testing

I'm having confusion.

my device is samsung gt-p5100 3g.

but when i custom rom with espresso3g it never works

an error appears your device is espressowifi

What TWRP version are you using?

 

[Freemaurer]

EDIT: I got it to work. l had the wrong TWRP installed. Works also with TWRP 3.3.0-2.

Thanks to developers pushing this G.Tab 2 thru Android Oreo, but lm having trouble flashing the coffee onto the device GT-P5100 3G Europe. I followed all of the updated instructions from the first page of this Thread. Installed Odin to Comp, flashed the twrp, was successful.
I followed also the instructions after installing the TWRP that flashing multidisabler might be neccessary for it to unlock. That failed (picture).
Then tried flashing espresso 3G, also failed. Device was normally wiped and after also advanced wiped; dalvik,system,cache data. I watched this video (

), but it doesnt go thru the install like in the video.
Any solutions ?

you are using a older TWRP well that causes problems to install Android 8.1, you need atleast TWRP 3.4.0-0 to install it without problems

Thank you for response, but it didnt work with TWRP 3.4.0-0, it failed, but it was successful with TWRP 3.3.0-2

• I most often use twrp from andi, AOSP rom, SLIM, LineageOS, Omni, I tried and it's the same.
• the error is still the same
• and finally my roms returned to the default version
• and everything works normally, but im only use rom in version 4.1.2

Look at Page 19, I posted the solution where it worked for me. TWRP 3.3.0.-2 and coffee 3g 20220213

Yes, Firefox requires really high resources. It won't even work on my Lenovo tab with 2GB ram and a decent processor.
Maybe try Brave?

Latest Brave wont work. I installed Brave v1.35.100 , one of the first versions. It works fluid for a 1GB RAM (but dont get to excited). It crashed and rebooted the Tab when l tried to open Discord Web app.

To clear this TWRP confusion, after wiping system, data and so on, you cannot install a zip, you need to reboot back to recovery zip after that to make it work. I use twrp 3.4 myself and it has worked for me using this method and will work on all unified recoveries by Andi (https://github.com/andi34/samsung_galaxy_tab2_secrets/blob/master/FAQ#L11)

Latest Brave wont work. I installed Brave v1.35.100 , one of the first versions. It works fluid for a 1GB RAM (but dont get to excited). It crashed and rebooted the Tab when l tried to open Discord Web app.

I don't exactly know why this happens, even firefox crashes and makes the tab reboot. Hard point is to get the logs (maybe last_kmsg or some service that writes logcat to a file)

New builds are now available (UnlegacyAndroid 8.1). Both espressowifi and espresso3g has been built.

• If your model is P3110, P5110, P3113 or P5113, download the espressowifi build.
• If your model is P3100 or P5100, download the espresso3g build.

What works: Wifi, bluetooth, stereo audio, autorotate, sdcard, gapps, USB file transfer, battery status, hardware accelerated video
What doesn't work: Camera (drivers don't support kernel 3.4), gps, selinux, you tell me

DOWNLOADS:

• espressowifi
• espressowifi md5sum
• espresso3g
• espresso3g md5sum

The md5sum files are optional. Use them to verify the integrity of the downloaded files.

INSTALL GUIDE (espressowifi)
INSTALL GUIDE (espresso3g)

CHANGELOG:
- Implement F2FS support (Merge request)
- Apply GPU accelerated video patch
- Upstream changes (if any)

The previous build is available here
Build scripts for the device available here
Automated jenkins builds are nearing completion.

I tested it last night so l wanted to give my feedback.
Bluetooth is working with mp3 and pdf/word files, but wont support transfer even small APK files, it says its not supported by Galaxy Tab 2, works with wireless headphones.
charging is recognised after couple of minutes (battery icon gets lightning sign), Brave works, but only the first versions like Brave v1.35.100 - l invite you to try others starting from there, latest Brave wont even start. Discord Web app is not working, in fact it tries to load in Brave but then crashes the Tablet and reboots the sistem UPDATE: after that crash, l tried again, and possibly after it loaded the page once again, l got presented with a QR Code. Feels kinda slow, but i dont need it for anything else but reading text. Vanced works, l installed it thru latest Vanced Manager. It sets the first page with Videos quite fast. Background playback works but if yu exit to home screen, yu will only hear sound, "try new features" doesnt show in Settings even if its the latest version of Vanced (17.03.38 - Build - 01.55.00) ; that small video screen wont appear over other apps. Videos run smooth after they load a bit after few seconds, except the FPT videos, they are lagging, but he probably doesnt use compression on his video content. scrcpy doesnt work even with USB - tethering turned on in Dev settings. WIN-Comp pushes the command, Tab freezes and than shows "snow" on the screen, after which yu have to reboot it over Power button. And the last part; Windows wont let yu safely remove Tablet from USB.

holla!

to get logs you need to run `logcat` maybe through adb as in connected to a pc, or just through a terminal on the device, no worries if you dont know how, I'll try to get those myself on my device

First of all thanks for the detailed review! About bluetooth i never tried copying files so thats a nice catch. Charging works fine for me, on usb as well, dunno what the issue is (bad cable?). Why use web app when discord app exists? About Vanced, please contact their developers, I have no clue about that. About scrcpy, please send in some logs and maybe create an issue on their github, so even their devs can help us out! Windows wont let you safely remove the tablet, this is new I'll have to dig into this once i get time. Anyways I'll add these to my ever expanding list of todos

What TWRP version are you using?

TWRP 3.4.0

 

[ginore]

Can you confirm that the latest rom available for GT-5110 (wifi only) is ua_espresso-8.1.0-20220213?

most likely yes. whats the problem

 

[ginore]

no problem, the rom is very good, thanks!

I was just wondering if any updates had been made to the February rom.

Its still original Samsung cable. The device was barely used before, so its like brand new. Charging got little laggie after running thru sum processing with the apps. When its not connected to a PC right before, it shows "charging battery instantly. For the Discord, I will try the app also on the weekend, just wanted to pack as small amount of apps on that "1GB RAM bad boy" as possible, so just tried it thru Brave browser. But it worked eventually (l updated the first review). Will send you the logs or post it here on the weekend; l will try to get them over PC and also report it on Github. Vanced also. You (and other devs) actually resurected my old tablet, so lm glad l can help

stupid question:
how does this rom compare to others? is it as fast/nearly as fast?
also, ive heard about ways to optimize android compiler to make android run faster, would that be applicable here? (uber toolchain or something).
sorry this question is so noobish xd, i just got this tablet from e-waste and im trying to squeeze some speed out of it (it has some half decent speakers, so ideally for media consumption).
also, could anyone help point me in the right direction for a fast custom rom? just looking for decent battery life and usable speeds.
