I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!

If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.

The last 3 weeks we with @bonuzzz worked hard to make stable firmware for t820 and t825 tablets.
Finally, it's time for the first release.

Instructions
1. Install twrp
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps

Work
Almost all working

Known Issues
Sound\mic during calls

Thank you so much

I hope the ROM is always better, as soon as I have some time I install it to report any bugs :)

Hi,

i've installed the ROM yesterday and i used it today in case of a working day.
I have noticed that he unfortunately does not switch to LTE - despite full receipt. The tablet uses at most HSDPA, which makes the ROM for me currently not really usable.
It is also a bit slower than the stock ROM, but tolerable - only the network connection is still a hindrance.

I bought the tab because I thought, as a flagship this device will surely get the lineage OS.
I am still very enthusiastic and really thankful that someone has made such a great ROM for this tablet- many many thanks to the devs!!!

regards
Ralf

Edit: after reinstalling this ROM is found the switch to change the preferred connection type to LTE. So i go on using it :)

Ok so, I gave the rom a chance and to be honest it works quite well.
Kudos to Valera and Bonuzzz for the effort, this is looking very promising.

I don't use the S-Pen nor the phone-calling stuff so, my experience with this build doesn't include those two.

General usage feels snappy, I only had some trouble while playing video streams on the stock browser and firefox. The problem went away while using chrome.

Tried a couple of HDR 4K files on MX Player and they seemed to play nicely.
Played around with the settings, everything cool.

The only problem so far is a huge battery drain during normal usage.

Aside from that, this is an excellent beginning.
Considering this is just a 1st release, it's very stable.

If you need any kind of testing, I'm more than willing to help.

kainanmaki,

Thanks for the initial testing. I have not flashed this ROM yet. I'm still observing a bit before I do so.

I'm curious, how do you define normal usage? Also, are you able to quantify the huge battery drain?

Thanks much!

Well, you should. At least it could give you a good idea of what to expect when the rom is ready.
I have never used lineage on a tablet so I wasn't sure what to expect.
For starters, normal use is just what you can imagine, youtube, chrome, mx player (hdr stuff), headphones, couple of silly games.

After checking how stable it was, tried Xposed -sucessfully- and every module worked fine (amplify, bootmanager, rootcloack, xnotify,youtube adaway). The drain is severe, you could literally notice the % going down ridiculously fast.

What's worst, my normal app usage and settings are designed to not duplicate what I can already do on my HTC 10.
So no GPS or Bluetooth, almost no applications doing sync stuff that I already have on my smartphone. (Gmail for e.g)
I always force wifi to sleep when display is off. Again, I don't need another device duplicating my smartphone.
LTE data is also off most of the time (and LTE works as expected per Speedtest -70 mbit-)
But again, settings are tweaked to maximize battery, while using it and while sleeping.

I have used BetterBatteryStats to take some measures, the drain is related to the core of the OS services.

A simple comparison with Stock. I just have started debloating touchwiz (very happy with the progress there too TBH), and barely scraching the surface of what can be done on stock, BBS is reporting 6.25 minutes per 1% of battery. Roughly 10 hours of battery of non stop use. After removing 85% of Samsung bloatware and its services, it's going to look even better. Samsung never ceases to amaze me with their never ending junk. So again, the rom is not ready for primetime. But that could change fast.

IMHO, you should install TWRP and do a backup of stock stuff and take a dive. Even if Lineage feels like android for smartphones, still works wonders. And you can go back to touchwiz in 3 minutes...

EDIT: Forgot to quantify the drain. The android energy forecast estimated 3-4 hours for a full charge. Closer to 3....

    Valera, is the project dead like the 820 version?
    Click to expand...
    Click to collapse

    Hi all
    Sorry, there were some problems for family reasons. It was take a time.
    The project is not dead.

    I will say more - last month there was a very active development of the oreo (lineage 15.1).
    And we were ready to publish the oreo (820+825), but there was a problems with the battery for now.
    Current status of the oreo:
    working: wifi, bt, sdcards, sound, vibra, sensors, mtp, spen, hw in videoplayers
    half working: ril + gps: samsung has own way for ril, it's differ from other companies. I used ril libs from note8 qcom variant + gps from leeco - only in this case gps working great, ril - sms\calls\ussd working, mobile data dnw. And still need fix problem with sounds in calls.
    all great, but battery drain is the main problem right now, it's lost about 40% by night. Hope very soon all will be ready.

    To disable FRP Lock, you have to enable OEM unlock in Developer options.
