there's an update on the russian forum

lineage-16.0-20190608-UNOFFICIAL-TB8703.zip

Lineage code update (round battery icon, new wallpaper application, night mode)

Update init scripts, fixed launch of some services

enforcing selinux

Build from pooled sources with Lenovo Ta4 10 plus developers, link to https://github.com/lenovo-devs

I installed it, seems to me that it drains the battery a little faster.

After succesfully wiping/installing rom/signing boot/installing GApps etc, the tablet boots for the first time and after the welcoming screen, tries to find a wifi network....and nothing happens.

What did there go wrong?
[Thinkpad Tablet Android Development] highwaystar_ru:
2019-06-08

Updated Lineage code. (circle battery animation, new wallpaper app, Night mode)

Updated init scripts, fixed startup of some services

enforcing selinux

removed telephony apps for wifi version

First test build from common sources together with Lenovo Ta4 10 plus developers : [MENTION=3208754]codeworkx[/MENTION] and [MENTION=9613333]yener90[/MENTION] . Common sources link https://github.com/lenovo-devs

Please do backups and report of success install especial on wifi version (have one report of bootloop after install on wifi version, but not confirmed).
[Thinkpad Tablet Android Development] wbn1:
Wifi version

Installed the first time on top of 2019-05-10 build and no boot loop.

Just now I made a clean install and still no boot loop.

Telephony apps are gone indeed.*

To me it seems the battery is discharging faster. Something wrong with my tablet..

*edit: shouldn't com.android.messaging and com.android.mms.service also be removed ?

[MENTION=7737930]highwaystar_ru[/MENTION] Absolutely amazing work. Please let us know how we can donate :)

Clean flash the 2019-06-08 version after removing 2019-05-10. Magisk installed. Everything working fine so far.

Edit: Wifi version
[Thinkpad Tablet Android Development] alex_under01:
Note to self and to others.... Wiping is fun but it's not to be overused.

My conclusion is that instead of wiping ONLY what's necessary (Dalvik/System/Cache) I was wiping EVERYTHING, thus deleting (I assume) essential files (drivers???) that every device needs, regardless of recovery type or ROM, to function properly.

Reflashing the Stock Rom and redoing the procedure from the beginning, wiping ONLY what's supposed to be wiped, solved everything.

So folks, DON'T OVER-WIPE :silly:

Hi, OpenGapps for Android 9.0 (Arm 64), nano release works fine for me.
[Thinkpad Tablet Android Development] jk77:
Wifi version:

- run magisk uninstaller zip in twrp

- dirty flashed the new version

- flashed su addon (since I had no use of magisk, if somebody knows how to get dolby back working, i'm interested btw)

- cleared cache and dalvik

- signed boot

-> all fine !

Thanks a lot highwaystar_ru !!
[Thinkpad Tablet Android Development] wbn1:
I installed Dolby atmos from this thread. The

magisk version doesn't work

, but the twrp one works quite nice. It backs up the files it modifies and it has an uninstaller that restores them, just in case.

You need to remove the AudioFX app ( org.lineageos.audiofx ) via adb or Terminal.

stole the idea from yener90's thread for the tab4 10 plus.

Compatibility for tab 4 8 plus

Hey. I have a Lenovo tab 4 8 plus (tb-8704x). I was wondering if this ROM is compatible for my tablet as there is no custom ROM for this device and the stock ROM is boring. I guess both are have the same specs.

Thanks in advance:good:
[Thinkpad Tablet Android Development] highwaystar_ru:
tb-8704x requires some kernel work and require actual device to test it, no one of current developers has it.

Hi,

I've upgraded to v16 and everything works fine, except that I can't apply for root access.

I've tried flashing magisk and SuperSU and according to the log in TWRP everything is installed ok, but when rebooting back and opening SU, for example, it says root cannot be found or alike.

Any suggestions?
[Thinkpad Tablet Android Development] rauliordache:
Hi :)

Before upgrading to LOS 16 (Pie) - currently I'm on crDroid Android 8.1, (Lenovo P8 - 4G version) I have some questions:

1. Does it still have the problem with the RTC Clock while there is no SIM card/internet connection? (back to default value of 1970 1st Jan after every boot)?

2. How much RAM is used by the system ? Currently - Android 8.1/crDroid - the system uses 800-900MB (after booting). Just as an idea.

3. [MENTION=7892893]wbn1[/MENTION] says there is a battery drain problem on LOS 16. Is this confirmed (on all Lenovo P8 devices)? On crDroid I can achieve 10 hours (!!!) of navigating+phone+occasionally streaming on an Extreme Power Saving mode - which is incredible. - with no battery drain problem.

I really want to try LOS 16, but your experience is the best feedback, before flashing it! :D.

Also, from my experience, I will try the cleanest flashing possible:

- flashing the stock ROM via QFIL

- flashing TWRP

- flashing LOS 16 (after full wiping).

(so I will not flash LOS16 just after wiping on the actual TWRP) .
[Thinkpad Tablet Android Development] wbn1:
1. I don't have this issue on the F version

2. almost 1gb right after booting

3. the issue with the battery has to be on my end, maybe the battery has became faulty. If I unplug the tablet while it's charging and it hasn't reached 100%, it will drop 4% of charge in a few minutes. I usually let it charge to 80%, and it will drop to 76% after a few minutes. I also see that discharging sometimes is not 1% at a time, it sometimes skips some numbers (44-43-41-40-..-30-28-27). This happens 3-4 times from 80-20%. But again, this could be my battery showing signs of wear. Out of all custom ROMs for this tablet, LOS gives best battery life.
[Thinkpad Tablet Android Development] Mhden2x:
In general, I find that Pie ROMs seem kind of laggy on this device. Did you guys notice it too?
[Thinkpad Tablet Android Development] rauliordache:
Thanks for feedback.

Reading the russian forum, it seems that the notifications (via SMS/WhatsApp/etc.) are not triggered while the tablet is in sleep-mode. After turning on the screen, all notifications come in cascade (emails, SMS, etc.). Both on crDroid and Lineage (Pie version). I'll try to investigate.

Also, the LED does not blink when a notification occurs.

I'll try to sumarise the bugs collected from users:

=== 26 Jun 2019 ===

= Both crDroid.20190505 and Lineage 16.0/20190608 =

1. The notification problem while screen is off.

2. Lagging in some games (also mentioned above by [MENTION=4841473]Mhden2x[/MENTION]).

3. LED indicator absent while a notification occurs.

4. [few users] Slower Wi-Fi Internet Speed (than 8.1 Lineage/crDroid)
[Thinkpad Tablet Android Development] wbn1:
I also noticed this. With channel bonding on for the 2.4Ghz band I was downloading with ~12 mb/s before switching to Pie. Now it went down to 9-10 mb/s. Tested near the router.
[Thinkpad Tablet Android Development] rauliordache:
Yep, exactly this complaint was stated. Maybe it's a Pie problem (and not from custom ROMs Lineage/crDroid/etc.).

Interestingly, the bad performance (lagging in games for example) is not generated by a low-memory/low-device specs. I really think that Pie (as a standalone OS) is not mature enough - in general, for all devices -.

[Thinkpad Tablet Android Development] carlosgreg88:
Thank you very much!

I installed this Recovery and it worked, I installed your Pixel Experience ... later I test this lineage..I have doubts about which is better.

I do not know if it was just me, but the stock rom was with several bugs ... incompatibility with several apps ... too bad, nor was using the tablet ..
[Thinkpad Tablet Android Development] rauliordache:
I don't know yet if the delayed notifications/SMS/etc. are due to Android Pie itself, or a custom ROM problem... any clues?
[Thinkpad Tablet Android Development] rauliordache:
Later edit:

After trying both Lineage 16.0 and crDroid based on Android Pie, I come with a feedback.

There are some problems with Pie (in general, not device-oriented), and some problems with custom ROMs. I will group into general/specific sections.

General issues:

1. In both ROMs (and confirmed that it's

not

a custom ROM problem but Android 9.0), the CPU is idling at 100%.... It's abnormal to have CPU(all cores) at @2GHz in idle (no foreground tasks, and background tasks set to minimum). In battery saving mode, 4/8 cores stay at @~1GHz. [img attached] + GPU at 560 Mhz without any game/GPU app in foreground.

2. Digital Wellshiting app should be killed with first ocassion...

Specific issues:

1. In crDroid (20190505):

- 8-10 seconds of screen flickering/unresponsiveness/black screen while switching from Battery Saving mode (extreme) <-> Normal Mode. With default wallpaper, it's better. With others, it's criminal. [no problems in Lineage].

- The hotspot function works .... limited. Maximum 1-2 Mbps. Need further investigation...

2. Lineage (20190610):

- Works better than crDroid (maybe due to the Launcher/Home which is lighter than crDroid version)

- System uses ~1.0GB RAM after booting up (vs. 1.4-1.5 in crDroid).

- Despite of these, it's lagging in some apps (Waze, for example). But, I think it's a Pie problem.

All in all, we cannot compare any Pie ROM with

crDroid 8.1,

for example, which is working exceptional.

In Pie, there are some overlaps regarding notifications. There are some notifications settings in Do Not Disturb settings, other settings in Notification menu, and also, we can find specific notification settings for each app. This is a bull**** for an operating system. After tinkering with all settings, there are no problems.
[Thinkpad Tablet Android Development] carlosgreg88:
Hello could you help me?

I installed the ROM lineage, I was using the pixel experience, I made a wipe and installed it.

But it does not have google services .. and I can not install them .. how do I solve this?

Why do not you have google services?

Does anyone use without google services?

I read before installing that says something about google services, but I did not understand ..

Sorry, I'm an amateur, I'm learning.

[Thinkpad Tablet Android Development] rauliordache:
I have found some bugs in the latest Lineage 16.0 (20190608):

- while the phone is off and is charging, pressing the Power button shows only the "battery icon" without % level. So, we cannot find the level of charging when it's off.

- the battery saver mode is not persistent after rebooting the device, even though, afterwards, the icon (and the menu settings) shows an active battery save mode .... How I found that? Using Phone Tester/CPU-Z, we can see that in battery saving mode the phone uses 4 cores at max @1Ghz, at peak. Enabling this mode, and restarting the tablet, we can see all cores (8) at max @2Ghz. So it's in normal mode.

If it's not possible to have a persistent battery saving mode after rebooting, just revert the UI/setting's text to normal mode, so as not to mislead the user.

- all in all, something (maybe a system package?) is maintaining all the cores at @2Ghz (or 4 cores @1Ghz in power saving mode), even though there are no work to do. As I said above, just opening an app like Phone Tester/CPU-Z (so one foreground task) elevate the CPU at max.

If you want to use Netflix from the playstore, you will need to install Magisk, so that your SatetyNet cts profile check passes. Otherwise, you can use the older netflix apk and just install that.

If you do install Magisk (you will need to flash it from recovery and sign the boot loader) after you boot, you need to clear the Google Playstore and Google Play services application data, so that it rescans your device and reports that your device is Certified in the playstore (you can check this in the Playstore settings area, your devices certified status).

Only Certified devices get the official Netflix app updates now in the playstore.

That way you can use the 7.20 build of netflix rather than the older 6.26 build

You install on pie?

And how can remove audio FX with terminal?
[Thinkpad Tablet Android Development] wbn1:
if you have root type this in terminal:

if you don't have root, use adb and type:

IDK how titanium backup removes packages, never used it myself, but you might need to restore audiofx with titanium and then use adb/terminal

Hi all,

I've found an issue (but I cannot confirm if it's ROM related or a general Pie problem):

Let's say, we are starting a GPS Testing app. At first glance, we can see 33-34-35 sat's (GPS, Glonass, Beidou and 1-2 from Galileo GNSS). TTFF = 1-2s - very good.

But, after some seconds /1 min, the Beidou GNSS disappears.

The GPS/Glonass are ok, while Beidou is...let's say volatile. So from 29/33-34-35 it goes down to 11/26 ....

Tried both with Force raw GNSS measurements ON/OFF.

===========

Also, I think it does not support dual-band freq, but it's okay (you can see in two of the pics). I just don't know why the Beidou GNSS is so volatile...
[Thinkpad Tablet Android Development] unreallove:

PLEASE don't think me as a trouble-maker or anything like that

The problem with offline charging is not a custom ROM related, but Android Pie.
