[ROM] "GENERIC" SC v2.0 USER/USERDEBUG - S905x2 / S905x3 - AndroidTV 9

[yakaaithiri]

Try it but only DEBUG version because you will be able to open terminal and reboot to recovery to flash stock rom.

Sure . i am gonna try the debug version only . waiting for my Micro usb A to A cable to be delivered.

Is there a way to flash ATV via TWRP ? any zip or backup file please share.

Folks, will this rom work with A95X F3 Slim ? . Its a Amlogic S905X3 device.

Have anyone tried it already ? . Is there a way to backup the current rom if something goes wrong ?

I have taken the backup . Is there TWRP backup or TWRP flashable zip available for ATV ? Can someone please share if so ?

TWRP_3.2.2_Android_9.0.zip Download and copy to external sdcard or usb drive. Boot into recovery and apply update (This will not overwrite stock recovery). You will be able to do a backup but you should have a stock firmware available so you can burn to sdcard in case thigs go really bad!

But I thought s905x3 supported L1. Is it possible that some boxes with same SoC don't support it?

No.. 99% of the boxes out there with a s905x2/x3 does not support L1

superceleron sorry for nagging so much, but one last question - I put a simple "android tv" splash as "bootup" logo, and after flashing it, it is shown correctly - but only during first boot. After that if I reboot, it shows me messed up superceleron logo, even though I have not even taken the logo partition from your ROM. I took only the "system" and "recovery" partitions. I am not able to debug how this bootup logo is getting overwritten and where. Any suggestion?

That one you need to figure it out by yourself hehe

ye i forgot... my roms were made for L1 so it as tee/optee since is needed for L1 support (the boxes that support it)

I have upload SC2 rom (userdebug version) for T95 Max+ here:

[drsam007]

superceleron I have a breakthrough. Seeing that "vendor" partition had lot of differences, I took only "system" partition from your ROM, and it works beautifully! I also did vendor partition cleanup by comparing what was there in your ROM. Thanks for all the work. This ROM is now far better than the stock - which was crap.

So, T95Max+ users, if anyone wants SC2 ROM, do let me know. I'll upload it somewhere.

EDIT: typo

Did some more debugging. If I do "logcat" on serial console, I can see following in the log:

So, I compared "vendor" partition of stock rom with SC rom, and I can see that there is no keystore related items in stock (e.g. /vendor/bin/tee-supplicant, /vendor/lib/optee*.ko, etc.)

[ 23.046960@2] init: couldn't write 4035 to /dev/cpuset/camera-daemon/tasks: No such file or directory

there is something wrong in the build you doing, if you ever get the error above there is issues in the apk's of the mix you doing!
There is not much i can help when that error happens, it can be a lot of things.

Thanks for the tip. I actually just used the system, vendor, product, odm and vbmeta PARTITION files from your ROM. Even if I take everything from your ROM except DDR.USB, aml_sdc_burn.UBOOT and _aml_dtb.PARTITION, the issue is same. I'll try to debug more. Thanks for all the help.

I have done some more debugging. I compared the serial output with that of stock rom. There are many differences, but I think main issue starts when it tries to enabled wifi. On working stock rom:

aml_wifi wifi: [usb_power_control] Set WiFi power on !
aml_wifi wifi: [pci_reinit] pci wifi reinit!
aml_wifi wifi: [wifi_power_ioctl] Set sdio wifi power up!
aml_wifi wifi: [wifi_power_ioctl] wifi interface dev type: sdio, length = 4
dhd_module_init: in Dongle Host Driver, version 100.10.315.3 (r771911)
======== dhd_wlan_init_plat_data ========
dhd_wlan_init_gpio: WL_HOST_WAKE=-1, oob_irq=84, oob_irq_flags=0x418
dhd_wlan_init_gpio: WL_REG_ON=-1
dhd_wifi_platform_load: Enter
Power-up adapter 'DHD generic adapter'
wifi_platform_set_power = 1
======== PULL WL_REG_ON(-1) HIGH! ========
aml_wifi wifi: [extern_wifi_set_enable] WIFI  Disable! 482
aml_wifi wifi: [extern_wifi_set_enable] WIFI  Enable! 482
BT_RADIO going: on
AML_BT: going ON
wifi_platform_bus_enumerate device present 1

But in case of modified ROM, it is:

aml_wifi wifi: [usb_power_control] Set WiFi power on !
aml_wifi wifi: [pci_reinit] pci wifi reinit!
aml_wifi wifi: [wifi_power_ioctl] Set sdio wifi power up!
