[ROM] Beelink GT1 / Alfawise S92 Stock & Nano Nexus ROMs (Android 7.1)

[TAOKTC]

Note that formatting as internal storage has always had some drawbacks, including losing access to internal /sdcard on the eMMC (which is usually much faster than SD storage).

There really should be no difference in behavior between Stock/Nano variants and the underlying OEM firmware (GT1_704N0 or TX8 Max), since the feature permissions (/system/etc/permissions) are unchanged. There are some significant changes for the TVStock variant for Android TV, but not for external storage.

The only thing that makes any sense is the change in behavior from Marshmallow to Nougat because of the changes to platform.xml above.

Thanks Magendanz for these precisons

So, there were some changes to the platform.xml file on Nougat, but these are shared by OEM firmware (GT1_704N0) and the new ROM based on the T8X Max.

This segment has been removed:

<permission name="android.permission.READ_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>

<permission name="android.permission.ACCESS_ALL_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
<group gid="sdcard_all" />
</permission>

And there's a new note here:

 <!-- These are permissions that were mapped to gids but we need
to keep them here until an upgrade from L to the current
version is to be supported. These permissions are built-in
and in L were not stored in packages.xml as a result if they
are not defined here while parsing packages.xml we would
ignore these permissions being granted to apps and not
propagate the granted state. From N we are storing the
built-in permissions in packages.xml as the saved storage
is negligible (one tag with the permission) compared to
the fragility as one can remove a built-in permission which
no longer needs to be mapped to gids and break grant propagation. -->
<permission name="android.permission.READ_EXTERNAL_STORAGE" />
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" />

So, has anyone tried reverting to the Marshmallow permissions?

Thanks Magendanz for your response. For information, I tested your rom under Marshmallow "[ROM] Beelink GT1 / Alfawise S92 Stock & Nano Nexus ROMs (Android 6.0)" and my SD card works properly with ES file explorer, Mi Explorer or Kodi. With your Marshmallow rom.
I hope we are going to succeed to solve this problem because your rom will perfect for me ;-)

For me also: I can see SD card in total commander and copy files, but cannot see in ES file explorer? Strange and air mouse sometimes stop for a second.

Thanks Magendanz for your great rom ;-)

I have GT1 Ultimate and it works perfectly but I have the same problem that some users with my SD card (Sandisk 64Gb).
I can see my SD card in the settings,
if I format it as removable storage I can see it and access to the files via the icon 'download' but I can't see it with ES file explorer, Mi Explorer or Kodi.
if I format it as device storage and define it as defaut, I can see it it and access to the files via ES file explorer, Mi Explorer or Kodi but I lose my internal memory !
I tested this rom Android 7.1 and TV Android 7.1 and it is the same problem.
I tested with the stock rom (7.1.2) and my SD card works correctly so it is not a problem of SD card. With the stock rom, I can access to my internal memory and my SD card.

Can you help me to revolve my problem, I would like to access to my internal memory (32Gb) and my SD card (64Gb) ?

Thanks

Awesome! If it's not fixed in the OEM firmware for the next update, I'll roll these in. Thanks for contributing to the effort!

Thanks. I did as i would my phone and flashed latest supersu in twrp. . Few things ive noticed, system sees the micro usb card inserted and with system explorer i can access files but using root explorer or solid explorer it see but wont connect. Checked all permission, etc. Lots of stuttering when using airmouse. Can't use remoteIME app to control device.

QUOTE=Magendanz;n666004]New build today, based on a new foundation. Let me know what you think!

Known Bugs:Bluetooth audio performance is awful on my Sony headphones. This needs to be fixed in underlying OEM firmware

First of all thank you for grate rom. Finally I have found good A7 rom for GT1 Ultimate.
Then about Bluetooth audio:
I replaced the following files (without lib64) with corresponding permissions and rebooted, then it works nice. BT.zip

The underlying OEM firmware is already rooted, so you can type "su" in Terminal and it just works. If you want the SuperSU gatekeeping prompts, you'll have to figure a way to replace the su binary that's already there. (For example, you could delete it and try SuperSU binary update again, but I haven't tried that yet.)

[jfive74]

hey. how to activate root? flash in twrp? installed supersu from play store and message say "su binary occupied". Thanks.

[otenet70]

In my case, the USB or Card is visible in the File Manager but Kodi does not see it

Disable amcodec and it will work.............

And yet KODI 17.4 does. Very strange.
