No rush. Just trying to be helpful. On a couple of the SM-T710 threads. I was wondering if you got the source code for the room to compile it or are u using something like Android image kitchen? From my standpoint this ROM is real stable, but the dev into Linageos forks is kind of stalled because of hardware issues like fingerprint.

It seems a lot of AOSP (Android open source project ) code is involved in Lineage and there is hardware issues with most if not all Samsung hardware running Lineage OS. Common problems across the board are fingerprint scanner , camera, Bluetooth, modem and wifi. And spen

Also most Samsung hardware had a hardware encryption implementation

I'm just trying to figure out if Samsung has any source code available , common hardware drivers , common modem hardware for their devices. They make so MANY varieties of the same device, it's like how many flavors of Intel processor you want to buy and which motherboard do you want to plug it into.

I am more into the driver layer in the kernel.

I used to complile a lot of kernels for FreeBSD routers I built. So Linux shouldn't be too different.

Since Android is open source , there just must be a Kernel compile process for Samsung hardware. That means there must be libraries for kernel hardware to be comipled in the Linux code.

However before we get to the Linux Kernel

The bootloader is doing something to load files, mounting hardware and memory and such.

Once the kernel is loaded the GTUI Graphic Touch User Interface is loading in the background. We call this Android. In essence is a shell, the things we see and interact to.

The launcher is just the desktop .

Just thinking out loud on my long weekend.
[Galaxy Tab S2 Android Development] BOIX:
Just wanted to say thanks for this rom and allowing my GT S2 8" to run well again.

I did notice a few minor issues/things, and after searching around, I'm still not clear whether they lie in the rom itself, or the apps.

* all amazon apps (amazon, kindle, audible, prime video, prime music) will not let me login.

- the error seems to be "Sign In Failure" "We encountered a problem signing in to your account"

* instagram won't play videos.

- even after tapping them on/off, closing the app and restarting.

Does anyone know if amazon prevents use of their suite of apps on this platform or with unofficial (modified) roms.

Lastly, thanks again. even with the minor issues this rom still works stably. Any updates on the next revision?
[Galaxy Tab S2 Android Development] Eliam77:
yes , very good work , can you do it for T715 ? :)

please :)
[Galaxy Tab S2 Android Development] tripLr:
All Amazon apps work on my device

Did you do a complete format of the user data too? And reinstall the apps?

Make sure you back up your photos texts etc to a SD card before u do a full wipe, or it's gone.

I have been using this ROM since it came out, and have no issues
[Galaxy Tab S2 Android Development] tripLr:

Is it possible to format data and cache to F2FS?

When I do it in TWRP it says operation not supported on transport endpoint, shows as F2FS but returns to EXT4 when rebooting
[Galaxy Tab S2 Android Development] vadar007:
Ok, so rooted T710. Have Odin on Desktop. Already have TWRP installed and verified I can boot to it. Are the next steps...

1) Unzip and copy contents of Poseidon ROM.zip file to T710

2) Put T710 in download mode, open Odin and apply BL_T710...md5 file

2) Reboot to TWRP and install boot.img file copied to T710
[Galaxy Tab S2 Android Development] vadar007:
Figure it out. Copy zip file to local storage. Boot to TWRP. Install Zip...all good.

Word of Caution. I started to uninstall some of the Samsung bloatware and ran into a problem when I tried to uninstalled Samsung Music (v16.2.08.22). Upon restart it hung on the SAMSUNG logo. Had to reinstall image and everything returned to normal. Seems to be some dependency on that service that locks up OS load process.
[Galaxy Tab S2 Android Development] georgesayer:
Firstly thanks very much for this, it is great the someone is developing for this excellent device.

I have a bit of feedback with the upgrading process I firstly upgraded twrp and then the bootloader as instructed, I then installed the ROM and the WiFi patch, but upon reboot it had unfortunately lost root.

I did however successfully re root the tablet by flashing SuperSU 'Latest(V2.82)' from the SuperSU website. (I am not allowed to post the url)

Not sure what happened, but all's well that ends well. :)
[Galaxy Tab S2 Android Development] flamand:
I don't know how this works, but is there any possibility to get the security updates incorporated? Unsurprisingly Samsung is not going to issue patches for the S2.

best of luck on your endeavors, Samsung Drivers are closed source present in the stock rom, you're free to download stock roms and take a look at them but they require a lot of experience to port them to Lineage, basically re-writing them
[Galaxy Tab S2 Android Development] ll3n1gmall:
Possible Malware Infection present

Our IPS noticed "ET POLICY Data POST to an image file (gif)" to the IP address 123.125.114.8 over port 80. There are no apps that appear to be initiating this connection. This is a means of exfiltrating data in a blank 1x1 pixel gif. I have cut network capabilities to all of my applications with an installed application firewall on the client (I don not use this device for much so there aren't many things installed to troubleshoot) and the connections are still being established. Once this IP was blocked at the network firewall new IPs begin to appear to other Chinese subnets that are also in or around Beijing. Here are the subnets that contain the offending IPs as per APNIC:

123.0.0.0/8

::ffff:123.0.0.0/8

111.0.0.0/8

::ffff:111.0.0.0/8

103.0.0.0/8

::ffff:103.0.0.0/8

180.0.0.0/8

::ffff:180.0.0.0/8

Clearly all IPs in these huge subnets aren't illegitimate, depending on your dealings with Chinese resources; but blocking these out was the only way to stop the bleeding. Once this was done I could still see the tablet attempting to call back out to these resources. Mainly to 123.125.114.8; but not only to that IP. I remember a supply chain report about malware being contained in the stock image for the Galaxy Tab S2. I was glad I was running this ROM when I heard that and didn't investigate. Now I wish I had been more thorough. I do not think the ROM developers planted malware; but more likely they used the already infected base from Samsung which unknowingly infected this Poseidon ROM as well. Which is a shame because I liked this ROM. If I had more time I'd do some forensics work and see about a potential fix; but its been too busy today and I need this device for a very specific purpose. So I threw LineageOS on it for the time being. If this gets identified and fixed please post back so I can check back. Hope this helps everyone! :)
[Galaxy Tab S2 Android Development] Ather:
That's really weird, and no i haven't added any malware in the rom either, are you rooted with supersu? Maybe that could be the issue since the app was now sold to some Chinese company
[Galaxy Tab S2 Android Development] ll3n1gmall:
Malware

I have magisk installed in this ROM. I thought it was used in Poseidon by default instead on supersu. SuperSu was sold to a Chinese company? I didn't know that.....sad :(

I sent it in service, can't be rapaired. I probably kill efs, it can't boot odin stock. It install without err but can't boot. Just restart when come to boot end.

So, I installed twrp 813, cm 15.1 or any derivative of it. Work perfectly. No reboot. Problem is gsm part for sure...

So I want to have twz rom, my idea is to flash 813 rom...

Would it boot?

This is something I was interested in for myself, a rom compile machine. while shopping on ebay, for used servers, i was suggestted this oldie but goody, a 4 x 8 core 32 core server in the 400 dollar range

this is what i am interested in funding [MENTION=494193]Ather[/MENTION] along with another device , provided we can ship to Bahrain, without much problems. So far there seems to be conflicting regs about shipping electronics to Bahrain.

I have a spare 4 core intel I5 laptop with a broken hinge, currently working on fixing, plus the one I am on an older HP with dual Athlon 64 bit cpu's but only 4 gb ram, that will NOT compile a rom. kernels yes, but not Roms.

currently compiling a 4.15.5 for my linux mint install on it.

I havent shared the gofundme on any other forums. Please post it with a link to this forum. [MENTION=494193]Ather[/MENTION], msg me and tell me a story about yourself and what happened, and why you like developing so I can add it to the story on gofundme. I want to update it this weekend.

The only difference in the 710 and the 715 is the Sim card.

So a person should be able to load the 710 and boot. PROVIDED

1. You have installed TWRP , and done a FULL backup of your currently running ROM , everything, modem boot system etc.

2. You can try to install the 710 posiedon ROM

If it fails, you can TWRP restore

Or,. Have [MENTION=494193]Ather[/MENTION] post his build process in detail, and if you own the 715, you can follow his instructions . I am interested in building my build server to accommodate ROM building for different devices. My laptop will Not compile that much stuff. Kernels only maybe.

If you can post your method, or build for the 715, it should load in the 710 . [MENTION=6005084]ripee[/MENTION] builds lineageOS single os for multiple devices.

I am working on my build server for devs to remote access. I currently have a memory error so it won't automatically reboot if there is crash. Also I need a couple more drives. I only have about 580 GB hard drive space. I have a 1 tb SSD on the way and I need some more memory. Sigh...

If you are patching the kernel and the root stuff in your Build, the insides are the same as the 710 except the modem/cell.

In theory whatever method u used will work.

If you make it, they will come.

FYI, Android Oreo is now running on a 32 bit note 4 snapdragon processor. Lineageos15.1 So the method they used can work with this device.
