Re: BD-E Debug Console [FOUND] + Setup Menu [FOUND]

Hello,
I've just receceived my BD-E8300, and the first thing I did was opening it
I tried to locate the debug console signals as I did with my BD-D8900.
It seems that Samsung worked to hide them a little more :
I spent a few hours trying to find the signals with my oscilloscope... without any success
The signals MUST be somewhere and I came to the point that the debug console might be disabled by default in the setup menu (which is surprising for a debug console that must be the first thing to work).
Unfortunately, I was not able to enter the setup menu. The KEY_FACTORY network method doesn't work anymore...
Firmware is up to date (1006).
Has anybody entered the E-series setup menu ?
Thanks

I did not find it yet...
- About the debug console :
I removed the heatsink to see if the signals were there. Some resistors under the heatsink, but still no signal...
- About the setup menu :
I started to objdump exeDSP to see if I could find something about it.
@Denny,
The magic code to start the debug menu on the console is still in the code
" 26120b8 616e6420 21212100 32303038 39393939 and !!!.20089999"

I found the debug port for the BD-E8X00
I didn't see it the first time I checked the signals; that's why I thought it was well hidden; in fact it's not
I used a minijack connector that I placed in the cable holder hole.
The 100 ohms resistors on the connectors are not really necessary (already on the board), but it's just an aditional protection.
and here it goes !

Wow, great findings, must have on wiki!
Now just check Is the shell input limited as on c and d series. Also how about (memory) registry write/read to patch memory...

Thank you Juziz28 !
Yes, the console only accepts hexa
I didn't find anything to patch memory in TDM.
Also, no shell in TDM...

Yes, same as C and D. Hope we can unlock this soon as for other series

It seems someone already did.

Edit:
It seems he did also BD-D5300...
https://twitter.com/zibri/status/138045175741165568
I wonder why he didn't release anything and as I see he is banned from this forum.
