[ROM][7.1.2][OFFICIAL] LineageOS 14.1 - SM-T805

[gellmar]

LineageOS 14.1

LineageOS is a free, community built, aftermarket firmware distribution designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Those who already have installed the unofficial version - can they now simply use internal upgrade functionality to get on the official one?

https://wiki.lineageos.org/signing_builds.html#test-keys-to-your-own-release-keys-or-vice-versa yes it is possible.

Migration did not work for me:

Unofficial to official migration
Error: /data/system/packages.xml not found

Nonetheless, tried to flash the official zip what failed with ERROR 7. What to do now?

Do we need to root the t805?

Thanks

Do you mean rooting the stock firmware before flashing TWRP? No, not needed as zip will overwrite BOOT (kernel + ramdisk) and SYSTEM and CACHE and DATA will be wiped on factory reset.

If you meant not this but "should we flash addonsu after LineageOS", I'd say it is up to you, but I prefer having root access for DriveDroid and other root-only apps. If you need to pass SafetyNet, you can always turn it off in Developer settings.

 

[Maheshwara]

If you need to pass SafetyNet, you can always turn it off in Developer settings.

Or install Magisk ???

 

[gellmar]

Or install Magisk. But I made all official and unofficial builds to pass SafetyNet if root is turned off. Presuming you need root for special tasks, you can turn it on, do your work and turn it back off and SafetyNet will not suffer.

Thanks, I managed to flash it perfectly. Well the first time i had a error in TWRP. But I then tried again, this time erasing all internal data and it flashed fine.

Where I am stuck now is gApps. I get error 20 and ive tried various "fixes" in terms of install procedures found on xda.

What check boxes should we pick in the gapps site you've linked us to?

Any tips/advice?

Last time I checked with OpenGapps arm - 7.1 - pico it flashed fine right after LineageOS and addonsu. Try rebooting again into recovery and installing gapps I mentioned and factory reset again.

Arm or arm64?

edit: sorry just saw you said arm.

All installed now.

I was about to sell this tablet, due to lack of updates. But stumbling across XDA has no doubt forced me to keep this tablet, which I think is still a top tablet.

Anyway, ll seems good so far, many thanks for the hard work!

Hey J4G3D, I've got a T805 my kids use mostly for Netflix, or I put movies on it when we go on road trips. I'm gonna try this out!! I didn't see any detailed instructions in the first post so did you selected arm, 7.1 and Stock for the google apps?

Thanks.

Hi

I rooted my device, just because it seemed simple to do so. Here:

https://www.theandroidsoul.com/root...10-5-lte-sm-t805-one-click-cf-auto-root-tool/

-Then I loaded custom recovery.
-Backed up anything I needed backing up
-Put the rom file, gApps (arm, 7.1, pico) onto a sd card

1. Boot into Recovery Mode (TWRP)
2. Wipe > Advanced Wipe > Select On (enable tick) for Dalvik / Art Cache, System, Data, Internal Storage, Cache,
3. Swipe to Wipe at Bottom of Screen,
4. Back to Main start screen,
5. Wipe > Format Data,
6. Type 'Yes' and press blue checkmark at the bottom-right corner,
7. Go Back to Main Start Screen to -VERY IMPORTANT---> Install Rom and GApps,
8. After you have finished installing the Rom and GApps > Wipe Cache/Dalvik > Swipe to Wipe
9. Reboot System

Job done.

Battery life appears to be much, much more stable now too. Apps also appear to be more stable, sky news used to crash every time I used it, at least once. Now it doesn't

Only bug i can see so far are the weather app not showing as a widget on the main screen under the clock. All is set and the recommended weather widget downloaded, but the weather just don't seem to appear. Also when having a pin on the lock screen, its only unlock-able via landscape mode and not portrait mode.

I have a perfectly working weather setup (including lockscreen weather) using OpenWeatherMap provider:

0. Remove all other weather providers, if downloaded
1. Install the OpenWeatherMap provider from LineageOS Extras
2. On the main screen, long-tap to have widget panel appear, then press "Widgets".
3. Add cLock widgetby long-tapping it to position on Main screen.
4. Under cLock widget settings open, select OpenWeatherMap as weather source on Weather tab and press a gear to enter website API key. When a permission dialog for GPS pops up, enable High Accuracy mode (that's esssential!)
5. Press OK everywhere to apply settings (dont use back button!)
6. Go to Settings - Security - Lock Screen and tap the gear to see Lockscreen Options. Tick the "Show weather on lockscreen" mark.
7. Let it load the weather and enjoy the notification in lockscreen.

Once you remove the cLock widget off main screen, the lockscreen weather will disappear.

Lockscreen rotation is enabled in Settings - Screen - Screen Rotation - Enable lockscreen rotation.

Got it with this instruktion. Thanks. Running the migration script via ADB while system is running did not work, but doing it via recovery was fine.

Hey J4G3D, I had no luck. My Tablet however is an SM-T805W. It's a Canadian LTE tablet with Rogers as the carrier. I've been doing some reading and it doesn't look to good for my device. Haven't given up yet so the quest goes on!! Thanks for the instructions though!!

Cheers.
