[Discussion] SM T819 - Lineage OS - A possible starting point! - Galaxy Tab S2 General

I have been waiting quite some time for a custom rom for SM T819 but I haven't see much progress in this. I looked for a device with similar specs for our device and came across this device which already has a Lineage OS build available. Its practically the same device but with a different screen size.
LeEco Le 2 Specs: http://www.gsmarena.com/leeco_le_2-8053.php
LeEco Le 2 Lineage OS Github Repo: https://github.com/LineageOS/android_device_leeco_s2
It will be a good starting point as I think for getting a custom rom for this device with a great potential. I have read that having spec devices is a great start to porting a ROM from one device to another without specifically building it from the source. However it includes a few build prop tweaks and changing few lines on kernel which I have no technical expertise.
Looking forward for your thoughts.

It's true, personally I don't have this tab but I had experience with a Tab I used which was similar in specs with S4 Mini ..
You'll get bugs though and you can base device tree from the Leeco Phone to build ROMs

Anything new here?
Seems like @tuxing built a modified T813 LOS build for himself, but of course no LTE in there. https://forum.xda-developers.com/showpost.php?p=73992901&postcount=552

i really hate the lack of support for LTE Tablets :/

Hi guys, I don't know if i am on topic but 'cause of this lack of ROMs for the T819, can I install the one for the T813? I know there is no LTE, but if I wanna try the ROM can I install it or it is incompatible with the T819?

Not that easy, but I had a nice chat session with @LuK1337 and he explained me how to get things built and boot on T819: https://forum.xda-developers.com/tab-s2/general/guide-build-lineageos-15-1-t819-t3721477
It's not that difficult as I thought. @LuK1337 told me it's simple and even I managed to get it working.

[09-06]SailfishOS & Multirom. How to set up guide

Hi sailors out there
When I'm going to read through the available sailfish threads the question about how to set up multirom & sailfish have been asked many times. So I thought I'm writing this little guide. I describe the procedure along the nexus 4 mako. But it have to be very similar on other devices like nexus 5 for example. The important parts that differs from mako are the kernel and modem image you've to use. I will describe the easiest way in my opinion. Experienced users have more capabilities to reach the goal. I will not describe how to install twrp recovery and unlock bootloader. Both are prequesites. Please use xda search or google to get this. But this little guide want's to be simple as possible. So let's begin .
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Beginning:
First we have to detect you're actual setup and where you want to go. Because nexus 4 is up to date I think the most common goal is to run android 4.4 as primary and sailfish os as secondary. Atm I have only paranoidandroid 4.4 on my device and will show you how to get everything working.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Requirements / Download following parts:
kernel aosp: http://d-h.st/A99
kernel cm: http://d-h.st/CCn
aosp = android open source rom. Ask in you're rom thread what version you're on with the rom
cm = cyanogen mod rom. Ask in you're rom thread what version you're on with the rom
Modem for nexus4 in version 0.84: http://d-h.st/cIJ
or
through an app in play store: https://play.google.com/store/apps/details?id=com.bpear.makomodem&hl=de
sailfishOS ea4: http://releases.sailfishos.org/sfa-ea/sailfishos-mako-release-1.0.8.19-EA4.zip
cm 10.1.3: http://get.cm/get/aWH
Multirom manager in play store: https://play.google.com/store/apps/details?id=com.tassadar.multirommgr&hl=de
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Before we're going on check up the following
1. All zip's you've downloaded have to be transferred on the device
2. Apps from play store are installed
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Installation process
Reboot in twrp recovery
Flash the new kernel
Flash the modem 0.84 in twrp. Or via the modem flasher from playstore. It's you're decision.
Boot back into android
Proof the functionality in android withe the new modem and kernel. Wlan working? Bluetooth? NFC?
Open mutlirom manager. Follow the installation steps.
After some time you'll be back in android. You have now the right modem, kernel and and a twrp multirom version on you're device
After this. Please reboot back into twrp recovery
There select the advanced button.
Then the multirom button
Select add rom and mark up the entry sailfish os
Press next.
Now you can choose two zip files to flash
zip1: Select the cm10.1.3 zip file
zip2: Select the sailfish EA4 zip file
Installation process is beginning.
After this select reboot
You automatically went into multirom where you can cancel the automatic boot process for the primary rom. Then you can select which rom you want to start.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
And the most important thing is to read: http://forum.xda-developers.com/jolla-sailfish/general/qa-sailfish-n4-thread-devices-t2727330 for further question before you ask. I have described there many things to start with sailfish. If you find this useful think about to press the thanks button.
I'm a bit confused why do you insist on updating the modem? I checked my modem version and it is newer so I imagine there is no need to update. Also why use such an old version ov CM?
Just asking because I did all according to your instructions except I used newer CM build and didn't update my modem firmware as it was already newer. But for some reason Sailfish wont boot. It just hangs showing Google at start.

Also I stated in first post why I only described the way I've did
Ahh ok nevermind got it working once I used the older CM image. Wifi seems not to be working but I guess that is because I didn't downgrade my modem firmware. I guess I'll wait for a more stable builde or better yet buy a Jolla phone. Just like having the nexus 4 as I can test bunch of operating systems on it.

Ok thanks for the hint. I used to be one of the early adopters of Jolla, but couldn't use it as my daily phone so I sold it, but now that the OS has matured I think I maybe swithing back. Even though I still think Nokia N9 had far better UI experience. If only some would port N9 UI to Sailfish

I feel the same, don't know why, but i just loved the N9 and the way the OS worked. I am not saying that sailfish is bad or something, but there Are somethings missing ...

They've practically done nothing since pre-release to improve and refine the UI, and so many incredibly basic features are missing (voicemail notifications, global copy and paste etc). The pulley menus are ropey and the active covers feature hasn't really been made use of much. They seem to be mainly concentrating on the Jolla Launcher for Android, which will definitely make them higher profile ... but if all their software engineers and UX guys are working on that instead of Sailfish itself, then it seems like cutting off their nose to spite their face.
I'm not a fan of Android and I can't see myself ever using WP or iOS, but the lack of progress and their production priorities are a bit dispiriting. I'm hoping that they're holding a lot of big and waited for improvements for update 1.1 (October).
Anyway, I'll keep it as my main phone for a bit longer, despite the fact that I have a Z3C coming early next week. Hope to see a decent Sailfish port for it soon.

Don't think I'll regret getting the Z3C, from a hardware perspective ... held one the other day, as a friend had been gifted one by Sony. It's absolutely superb. Granted, I despise Android .. but for when the Jolla ****s itself / runs out of battery / when GPS or a camera is needed / roaming / skype /outdoor use, I can suffer it until there's a Sailfish port.
Hopefully as work is already under way for the One Plus One, the identical SoC used in the Z3 & Z3C won't be too much additional work.
For all the moaning and groaning about Mediatek, I'm guessing the simplest and best port of Sailfish will probably be for the Meizu MX4, as there'll be an Ubuntu ROM for it, and libhybris is used by Ubuntu Phone ...
Also, hopefully future iterations of the HADK will smooth out some of the problems porters are facing.

it's the same for me...
The SoC in your z3c and 1+1 is actually the same as in z1c, I guess – 8974 vs 8974ac – only higher clocked.
You should not suppose that mediatek SoCs will be easier in general just because of is one working device. Jolla runs a Snapdragon and it works perfectly, most of the devices sailfish is currently ported to run snapdragons – with very different results.

I wasn't saying Mediatek in general will be easier (though it's possible), but any device with an official Ubuntu ROM certainly will (should) be - Meizu MX4 (Mediatek) is the first of those.
P.S. The Z3C is fantastic ... though unfortunately in black as opposed to the red I ordered (it's being swapped tomorrow).
Thank you very much for these instructions. i have one question though. In order to download CM 10.1.3, it says to click that link which takes you to download CM installer app. Ive used that app before and as far as I kmow, it doesnt let you choose which version of CM you want to install, instead it just sets you up to install the newest CM 11. I downloaded 10.1.3 from their site. Either way, no big deal.
Also, which kernel do I download to install? Aosp or CM?
Thank you
Still up to date
Hi,
are these steps still up to date or should we follow a different set up guide to install the latest sailfish OS on the Nexus 4? Because most, if not all, the links on the first page end up 404...
Bluetooth sync from Jolla to Nexus 4
Flashed my Nexus 4 with the factory 4.2.2 from google with radio .48 and then flashed cm-10.1-20131003-SNAPSHOT-TREATFORCOOPER-mako-signed.zip because that seemed to be the 10.1.3 mentioned in the guides to end up flashing the latest sfos from this guide http://forum.xda-developers.com/nexus-4/development/rom-sailfish-os-community-port-t2969823.
I didn't try calling, it has 3G network working and wifi is working but I can't seem to get the contacts from my Jolla phone using the Bluetooth sync from the settings.
Anybody has some advice on this?
Just had a good look at the wiki of devices on the mer website and found out the bluetooth is not yet working on the Nexus 4...
Works perfectly on my oneplus one

[Q] [Request] Custom rom for Changjiang S1

I'm using this phone for a while, but since it is made in China and lack supports
It is still in 2.3.x branch, which contains some known security issues
So, I'd like to know how to build a custom rom for it, my friend told me Slim is one of the most stable custom ROM on the run, and fits my minimaist style, can you give me some advice?
P.S. I've been looking into many Chinese sites, but still I can't get the full list of device tree
EDIT: seems it is a mtk6516 CPU with dual SIM
it has some different model names:
Meizu G11
Chianjing A007 or V7
found some maybe useful specs.

[Request] A Clean OS for the Tab A 7.0 (SM-T280)

Hello there
As the title tells you, i would like to have a clean OS for the Galaxy Tab A 7.0 (SM-T280)
With clean OS i mean a completely debloated rom without any extras. As slim as possible. Just a launcher and Core GApps (Playstore + Maps)
Maybe a debloated ROM or a debloation script. or a List of removeable Apps
I notices that the LTE version of the tablet, the SM-T285, allready got some non Touchwiz roms.
CM13 by Jedld and CM14.1 by Jedld
The best what could happen would be, if a developer from the T280 could make it compatible.
Jedld said:
SM-T280 Users: Unfortunately this rom would probably not work on it since the SM-T285 and SM-T280 have different kernels and slightly different hardware. I don't have access to this device so it would be hard for me to port it over. However I believe there are a lot of similiarities in the device tree that can be shared. If a dev with the SM-T280 is interested I can probably help.

Greetings!
A month ago i inquired about the likeliness of a ROM for the 280. There was some work being done on it but unfortunately it stopped. As long as devs don't have the device, no work will be done for it. So unless we (requesters) bundle and buy a 280 for a dev (something unlikely to happen) we can only hope.

Could we build a custom rom from the sourcecode provided by Lenovo?

Hi,
As the owner of a Nexus device, I am used to regular OS updates with included security patches. Since my Android Lenova Book has not updated yet, I started to look around
to see what could be find on the internets about that. I did not find much, but on the Lenove website I did find the Open Source Code for our Book.
http://support.lenovo.com/nl/nl/products/Tablets/Yoga-Series/YOGA-Book/ZA0V?tabName=Downloads&linkTrack=Mast:SubNav:Supportrivers%20and%20Software|Drivers%20and%20Software&beta=false
After downloading and unzipping it, to me it seems that these are the prop files you need to create a custom / updated rom. Since I am not that savvy on the subject, I only compiled a few roms, It would be nice if somebody could tell me if this is indeed the code that is needed to compile an updated rom and what steps should be taking to make this happen?
gr.

I, too, would love to see this happen.
I own the Windows version, but I've been flirting heavily with the idea of dual-booting. The major obstacle at the moment appears to be that Remix and the other x86 android builds don't recognize or support the halo keyboard. I'd love to have a ROM or something I could install to get the proper Android experience.
I'm down for this... providing my Book arrives soon (in AU so it'll take its time). If I find anything, or get enough free time to throw together a custom ROM I'll update. But I can't guarantee the latter (custom ROM from myself) as it will be a big learning experience.

Have you had a look at the current version of Android Lenovo provides? That certainly does support the Halo keyboard.

Building Lineage OS for the Samsung Galaxy Note 4 (N9100, trlteduos)

Hello xda community,
I would like to try my hands at building Lineage OS for the Galaxy Note 4 Duos. I was a little surprised that there seems to be not even an unofficial build for it (or cyanogenmod for that matter). Is there some technical reason why it hasn't been attempted yet that is specific to the Duos?
Otherwise, I'd be happy if someone could point me in the right direction. Maybe someone who already did it for a different model could post a basic guide since I have no experience yet in this area.
Speaking of it, my current level of experience is that I have rooted and flashed roms on android phones a few dozen times, and developed a handful of apps for android. So hopefully it's not too far outside of my skill-level.
Thank you in advance.
You can take a look at Note 4 General section, a new thread was made on how to build LinageOS for the Note 4 N910F/N910G. N9100 will not support 2nd sim if im not wrong, you need a dev who want to work on this project
Try this:
https://drive.google.com/open?id=0By...llGSnVyVDVfRlE
I downloaded this from the Chinese website. The latest build is 29 April. Donno why. Give it a try.
Thank you very much, I'll give it a try when I get to it.
Btw. the url is incomplete, I'm trying the original thread.

Kind of. Fingerprint and HDR camera don't work, which was expected, but for some reason phone calls don't work for me, I can call and receive, but there is no sound on either end. Otherwise everything seemed fine and the phone performed relatively well.
