i have just bought one, BTV-DL09 currently on Emui 5.

Bootloader is locked. I will get that unlocked.

Can you clarify after bootloader is unlocked what are the steps to upgrade to 17.1.
Read through some posts where people have went 15 first...Not clear on what the procedure is or what version twrp i need first.

My media pad is currently on emmui 5. The keyboard was missing but was able to dowload keyboard from playstore/

Tablet is showing as model number d-01 j and version NRD90m test-keys

Tablet is working fine apart form rotation is now not working. ( using a rotation manager to help with this at present)
Bootloader was unlocked, i get the device waring at the start but i'm pretty sure its locked. Some fastboot commands that i cant run. like flashing twrp again.

I would like to do a couple of things

  1. Upgrade to 17.1 - Can i do this with what have at present after unlocking bootloader. Flash twrp, wipe and install the Ziip?
  2. Will i be able to fix the rotation? Does lineage have asny of dtata files like sensorhub etc...
some guidance would be great on next steps.

I guess rotation does not work because of the test-keys firmware that's been flashed into the tablet. You'll get it to work in Lineage.

I'm not sure how to proceed in your case, it seems you have Japanese model... I think some people has done it before, maybe you could search in the forum.

The tablet had been converted from JPN version. When I originally got it, it had c100 firmware

The problem is, file downloads for firmware are difficult to get. I did find EMUI 5 which is needed before going to Lineage however it didn't rotate, no default keyboard and it is the test keys.

I can again revert to EMUI 4, the main issue with that is the wifi sucks on it. The speeds drop on it where as on emui 5, the wifi is fine.

I gues im not sure does it matter if its test keys or not. As long as it is EMUI 5 then it should upgrade.

On a side note, on thios build I can no longer access Project Menu,, tried the calculator method which didnt work. No dialler installed by default.

After you use lineageos a d rotation no longer work. You need to flash something back to the original.

I forgot what's the "something" is tho.

시스템은 twrp 터치에서 종료됩니다.

해결책은 어디에도 없었습니다.

나와 같은 케이스 문제가 있는 사람은 없습니다.

다른 버전을 설치했지만 동일한 증상이 발생했습니다.

방법을 알려주세요.

The system shuts down at twrp touch.

The solution was nowhere to be found.

No one has the same case problem as me.

I installed a different version, but the same symptoms occurred.

Please let me know how.

Wi model? if so did you install the boot image?
12. If your device it's BTV-W09 please install now boot_btv-w09_xxx.img
( Install -> Install Image -> choose "boot_btv-w09_xxx.img" -> Select Partition to Flash Image: Boot )

    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. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

    Reporting Bugs
    • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
    • If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.
