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

[superceleron]

superceleron I checked stock firmware, and the kernel version is exactly same as that the one in your ROM (4.9.113). So I just replaced the system.PARTITION and vendor.PARTITION files in stock firmware with yours and flashed it. On first boot, it showed my original T95Max+ logo, and then it showed standard ATV boot animation. But it was stuck on that. I waited for more than 5 mins, but it was stuck. I rebooted to recovery, and it still has original recovery. I rebooted again, and now it showed your "freaktab" logo first, but it was all messed up - it was shifted by half, and colors were all greenish. But immediately after that it showed standard ATV boot animation. But again it was stuck. Do you know what could be wrong? I am able to flash back stock firmware so it is not bricked.

I did not try the other option of just replacing _aml_dtb.PARTITION from stock to your ROM, because I am not sure if the name in dtb is same as expected. I don't know how to extract the DT from that partition. I tried gunzip on PARTITION file and it gave _aml_dtb file which is binary blob. Then I tried "dtc" command with various -I and -O options, but none are working and it is not able to read the file. I tried running "dtc" command directly on "_aml_dtb.PARTITION" file too, but no luck.

Replace the boot.PARTITION with the one from my build, leave the stock dtb and uboot for now!
Ho and the messed boot logo is because in my rom the bits used is 24 and the one support by your stock uboot is only 16.
Also replace the product.PARTITION and odm.PARTITION.

Yes it "should" work if the dtb has the same name internal name as the uboot is waiting for, that is for the s905x3 devices : sm1_ac213_2g and sm1_ac213_4g

Great work on this rom. I have magicsee n5plus 4g/64g too which is supposedly DDR4. I hope the newer version of this rom works, but I am not trying yet until confirmed working.
I attach DTB and DTS for this box if it helps in anyway.
Also does this rom support mounting loop devices?

well about the loop can't tell since i didn't try it..
The DDR4 is not in the DTB is in the uboot, the only way for you to know is grabbing a serial output as soon as you connect the box!
Also that dtb is from the 1gb ram.

Not working on Magicsee N5 PLUS S905x3. Rom error while flashing.

Updated first post with v2.0, enjoy!

hoo i see, the issue in your box from my build is the emmc is not compatible with my DT...
Anyway just as soon as you turn on the box just keep pressing enter key in serial terminal until you get a shell, something like "g12a_u212_v1:>"
When that happen, just type "update" and press enter ( without the "" ) and connect the usb cable and voila you can flash the box!

Thank you so much !

yes you need to replace both partitions, system and vendor and hope the kernel of that stock rom is not that old!

Thanks, I'll try it. If it does not work then I'll try replacing dtb

Okay, thanks for SC and sagert.

Hello sagert:
How do I extract dtb from the factory firmware? and how to paste it into this firmware?
What tools do I need?

Using the Amlogic tool v6.0 .

[superceleron]

superceleron or another question - what if I replace just system.PARTITION in my stock rom with what is there in your ROM?

yes you need to replace both partitions, system and vendor and hope the kernel of that stock rom is not that old!

Hi SC, if I can provide the dtb files of this device, so will this device be supported in the next release?

no mate, it wont work like that unfortunately.

superceleron I have T95 Max+ S905X3 device. Most probably the DTB included in your img might not work with it. Would it work if I replace "_aml_dtb.PARTITION" file in level1 of your img with the one that I have in my stock ROM? Do I need to update/replace any other file?

Yes it "should" work if the dtb has the same name internal name as the uboot is waiting for, that is for the s905x3 devices : sm1_ac213_2g and sm1_ac213_4g

From your working firmware android 9, take dtb and paste it into this firmware.
