[ROM] [UNOFFICIAL] LineageOS 13 |ASUS Memo Pad HD 7 (me173x) [MT8125]

[filus]

After having had several problems with the latest versions of magisk on this device, I have successfully tested the root by flashing via recovery of addonsu, the official root method of lineageos. By doing this in the developer menu you will be able to activate the root and manage permissions. Attached both the root and the unroot. I haven't tested the unroot but it should work too. If the rom developer wants, he can attach this alternative root method on the front page.

I wanted to know if other users have had problems with crashing or closing after opening with the latest updates of some apps. If so, what could be the cause? Example: Voice Aloud Reader and Youtube Vanced... In the case of Voice Aloud Reader if I manually install the apk it doesn't crash after opening it, if I install it from the play store it crashes after opening. By chance you should change the device name to build.prop to avoid problems with updates?

Does anyone have an issue with the device rebooting itself after you have shut it down?
The tablet does this without plugging it in.

Thank you

Hi, great job. On my version with the LG additional kernel everything works except BLUETOOTH. It is visible and recognizes the devices, it pairs only in appearance but does not communicate. With the version "ASUS_ME173X_AOSP_20160929.zip" everything works, but once you switch to 12 or 13 the bluetooth does not work. I have tried the different tips already posted above to fix wifi problems without solving the problem. How can I solve. Sorry for my immature English.

Hi all,
I've just tried to download the "Unlock_Bootloader+install_Recovery.zip" through the download links but the link that opens up says no mirrors found. Does anybody have the file they can pass on? thanks

Rectification: the tablet does not communicate with mouse-like input devices. I've tried with different devices and it doesn't work with mice. For example: with my smartphone it communicates and exchanges data, but with a Trust or other brand bluetooth optical mouse, even if it recognizes it, it does not paring.
How can I fix it please?

Hello & thanks to @superdragonpt for the efforts to prolong the usable life of this tablet. I have one question - the HW is already very dated and the CPU governor "hotplug" does not help with the responsiveness of the device. Is it possible to change the default to "performance" (or maybe "interactive")? Even if this will shorten the battery life.
I used the terminal in TWRP to change the governor in /sys/devices/system/cpu/cpuX/cpufreq/scaling_governor, but apparently Android resets it at boot - even with root and an app to set the governor Android defaults to "hotplug" unless the app is explicitly set to change it at boot...
I am planning to give the tab to a casual user and I really do not like the idea of a rooted device in their hands...

I've noticed this also... GAPPS on this tablet makes it extremely slow.
App updates have been increasing their memory footprints .

Wait for my next release, several issues caused by the low ram ( 1GB only) of this device have been greatly improved ( but don't expect miracles ofc)

nope

Well it does have an ancient BT chip, probably just not compatible with some recent devices, Currently i do not have bt mouse to test it out, works ok with my bt keyboard ...

Yeah you can use Kernel Adiutor app ( or similar app) to change CPU governor on-the-fly, yeah thats normal to default to hotplug at reboot, you could set "x" gov to be set at boot, but you do need to keep the app+root to do that.
Changing default gov to performance isn't an good idea, this is one of those matters where everybody haves their own opinion.
Hotplug can be very conservative indeed, i'll check some govs i've used on other MTK's to see if they can be usable here, i also don't like hotplug that much.
i did already worked a bit on sakuractive gov, for this device, had to do some fixs for it to build and be usable, but i just can't remember why i haven't merged the commit into my main branch... Need to re-check that


cheers

Good day. After installing magisk on a tablet with an LG screen, the tablet reboots cyclically. However, if you flash the kernel again, the tablet will boot again, but without root ... You know how to solve this problem?

 

[superdragonpt]

I've been testing today, the latest magisk builds.
Tested every build on clean flash:
Builds v24.x and v25.x do NOT work on this device. The inclusion of vmbeta for latest android versions, broke compatibility for older Android versions ( at least for MediaTek)

Magisk v23 works fine, as always


Added this note to F.A.Q.


Cheers

Hi. After an update my tablet is still turning on randomly after shutting down.

This man is more dedicated to keeping this ****ty old tablet alive and updated than I am to my career lmao
Seriously tho, thank you for your efforts, I've been using this tablet as a secondary monitor for years now, it's perfect for keeping discord open on the side

The only problem is that it runs out of battery and turns off from time to time, even tho it's constantly plugged in... Am I the only one facing this problem? Hopefully this latest build fixes that, I'll update you on the matter after I flash it.

Turning off while it's plugged in?
Well i never faced that issue...

About keeping this tablet alive, well i can now say for sure, that this device is not going to die on an Marshmallow release hehe

 

[Evg4oxw0lF]

I'm sorry to bother you, but you haven't tested Bluetooth on this tablet. for some reason it does not work for me on the latest firmware version, but it worked properly on the previous one...

Weird ...haven't made any changes on Bluetooth.
I'll check if bt is working on my side ( don't use it that much really)

Thanks for pointing it out, the June 2022 build indeed got Bluetooth broken by mistaque.

 

[superdragonpt]

Build 20220718

Fixed Bluetooth, that got broken by mistaque on 20220629 release


Cheers

 

[superdragonpt]

Edit. Wrong thread

 

[superdragonpt]

I can now reveal what has been my main project in development for quite some time ...

Still in Alpha but already got some things working

This has been extremely hard to get it to boot ...
I guess this very very old kernel 3.4.5 was never meant to reach this far haha

cheers
