Hello. I got recently BD-H8509s. Its on firmware version 1013.
Is is possible to install SamyGO or root this device?
When i used DNS 46.101.161.175 it shows me that im offline (cannot connect to network). And when i try firmware update (downgrade), im getting error 800.
Thank you.
BD-H8509s support
UART found
So, i found service guide, and conncted uart (green dots on diagram).
It seems to be working.
I also pulled up instead of pulldown some secure pin. Idk what does it do, but device did boot in non-secure mode so i left it pulled up.
I found CFG (BOOTCFG) pin which is pulled up by default. When i connect it to gnd, device doesnt boot. When i connect it to gnd after boot process starts, i got into shell, but i wasnt able to send any commands. Idk if i dont have priperly connected TX(pc) to RX (samsung), or its expected behavior.
For uart there is missing ic on bottom side of pcb, which seems to be ttl<->rs232 adapter. But soldering on mcu side of those resistors seems to do the trick.
That side of resistors from capacitor side is from left: 3.3v, RX, TX. And i scaped solder mask left from 3.3v resistor for GND, so i can connect max3232 (uart to rs232) from that one spot on PCB.
From log it seems like i have firmware from year 2017, and root is working up to 2015? So i would need to downgrade first.
This is 1007.1 (from 2015) firmware:

Is there any downgrade package for this BD player? Is it even supported by SamyGO?

Re: BD-H8509s support
Is firmware downgrade, ans patched firmware with samygo available for this bd player? If so, i guess its behind paywall.
Ik ok to donate, but im not sure if its even supported.
