Thanks for linking this tool, the one in the pdf provided by Boyue wouldn't run and gave me congif errors no matter what. After an hour of scouring I came across this forum and was finally able to update my likebook mars.

Now to wait to download and install 2020090714.

ignore the rest of this just seo terms.
Likebook mars loading config file failed

I just ordered the Likebook Mars from Amazon. Presumably it comes with Android 6.0. Would it better if I upgraded it to 8.1 first thing or does it not matter?

Also, does Boyue provide OTA updates for Android 8.1 the way they do devices running 6.0?

@raygj
I am not happy with the update. I would like to go back to Android 6.0.
I solved the problem of formatting the 128 GB by formatting the memory card to NTFS under Windows. If the memory card is formatted as exFAT by default, the format will crash on Mars.
Calibre Companion: Under Android 8 it is no longer possible to simply copy the calibre directory onto the SD card. I cannot then give the path to the directory. But I can integrate the e-book reader as a wireless device in Calibre. It is important to specify the port address. It didn't work without it. So far it works, only very slowly.
Thanks for your help.

I would be interested in whether the Boyue Likebook devices under 8.1 also work with SD cards larger than 128 GB.
My Alita and Ares also work with Samsung 512 Evo Plus cards under Android 6.

Yes, no problem with that. I'm running Android 8.1 on my Likebook Mars with a 256GB Samsung SD card, no problems.

That's fine - in my Ares and Alita there are Samsung Evo Plus 512 and I don't want to lose this opportunity with Android update.

I need rotation control that works in android 8.1 . Whatever program I use, I select orientation enter any app and the orientation resets, then I see the programs controls on notification area has disappeared meaning it is closed when I open any program after that , for example rotation control pro. I need permanent orientation control at least.

After following the instructions, my T80D is stucked in a boot loop sequence. Before it, I could see a black screen with a white circle. Is it normal being in such state for several minutes? Somebody can post the dump files of the new version?

SOLVED: I repeated the same steps a second time. Now, it works!

It's very important to read the update instructions *very carefully* before doing the update since leaving out even the smallest detail can have bad consequences for your device. Upon doing that, you would not want to waste time setting up Mars under Android 6.0, only to have your work erased during the update.

As someone who did do the update, I cannot recommend it due to several unpleasant surprises. First, the SD Card support breaks for Samsung SD card formats. Second, and surprisingly, Boyue's own default reader is worse in the 8.1 update than it was in 6.0 - forcing me to rely on KO Reader in the Mars with 8.1. These issues lead me to suspect there are other problems lurking, and there hasn't been update to correct the reader or SD card issues. Finally, while I can be as happy as anyone that some sophisticated users, and users sensitive to the placebo effect that updating affords, report improvements in performance, I have noticed no benefit from the upgrade - only problems and frustration. To be safe, I got an Alita before updating the Mars, and use Alita with 6.0 now almost exclusively.

Good luck.

Folks want just android 8.1 and front light, they don't care reading app!. No one shows his reading experience.

Good luck.

But with 8.1 you can download more advanced apps. Have you tried anyone?

Upgraded to 8.0 then over wifi to 8.1 and now the device freezes 2-5 minutes after restart.

the first boot up is slow as it is checking all storage for errors.the second boot up should be fast.
if it is still very slow then do a factory reset.

Having updated countless android tablets & phones in the past, this is one of the easiest of them over all. Google play store comes enabled , and we can't disable it on the settings like before (but can be disabled with other programs) Installed feedly for rss reading, kindle for android for my collection on amazon, audible, files by google , telegram (for certain book groups) , kiwi browser (to be able to use desktop chrome extensions), voice aloud (for tts with other programs) and hidden settings for disabling enabling some programs easily (like play store) and of course tachiyomi for mangas

@patientxtr
- how to instal those "hidden settings" - it will come in handy to disable battery consuming stuff for sure!?
- also what launcher are u using?
- is KWGT widget possible?

Another interesting option once rooted is to monitor any suspicious app sending data in the background. Now you can debloat/disable unwanted apps and have full control of your system.

@2rl So how can we get rid of those battery sucking apps other way if Your idea doesn't work as we know?

ps. how is the battery life after upgrade (nd does anyone have original 6v. rom in case of failure?)

ps. @Motobylette am also thinking how are doing marses with 8.1 already installed while purchasing them o.o is it the latest good v or...

Hidden settings for miui (I know this is not miui but it works for some programs)
https://play.google.com/store/apps/d...han.sets&hl=tr

I disabled within it :

Android Keyboard (AOSP) -I use hacker's keyboard-
Google Play Services
Google Play Store

Some programs says that they need google play services to run, for example telegram but in the end they run with it disabled, so no need for me.
====

If you really want to disable stuff though, you have to use adb commands by connecting the device via usb cable to pc.

Here is some stuff I disabled and command I used -not the whole list-

Connect device via usb cable to a pc, have adb tools ready, enter command prompt.

adb devices
(to be sure device is connected and can be used via tools)

this is the output for me :
List of devices attached
CNBT80D20200600482 device

to list installed apps on the device enter this
adb shell pm list packages

and finally and example to disable any app from the list
adb shell pm disable-user --user 0 com.android.providers.telephony

change com.android.providers.telephony to any other app name, but of course be careful not to disable any important system app.

You can of course enable-disable google framework from the settings and after that if you disable these I listed below it would be better.

package:com.android.providers.telephony
package:com.android.providers.calendar
package:com.android.browser

(I don't use default browser, I use kiwi browser)

package:com.android.providers.downloads.ui
package:com.android.vending

(this is the play store, and again I don't use it I use aurora store which works with google framework and all these stuff disabled)

package:com.google.android.gms
package:com.android.inputmethod.latin
package:com.google.android.feedback
package:com.android.providers.blockednumber
package:com.android.providers.contacts
package:android.rk.RockVideoPlayer

(finally this is the video player installed on the device, tried it once , it is not practical so no need to have it here)

To enable any disabled app again from the adb command ,
example:

adb shell pm enable android.rk.RockVideoPlayer

IMPORTANT !!!! BTW you can enable stuff disabled with ADB commands with Hidden Settings BUT if you want to disable them again you have disable them from the command prompt.

The thing is other than google play store not much is needed to be enabled again for me so this is mostly a one time thing with adb tools\ disable stuff and forget. And also I updated two times via System Updates while this stuff is disabled and didn't have any problems.
